Selection guide for DC circuit breakers 0

Types of DC distribution systems

There are three types of DC distribution systems (see the table).The operational voltage in conjunction with one of the three systems determines the number of poles taking part in current interruption.

Selection of a circuit breaker depends essentially on the distribution-system parameters presented below which are used to determine the corresponding characteristics:b type of system - determines the type of product and the number of poles connected in series for each polarityb rated voltage - determines the number of series poles taking part in current interruptionb nominal current - determines the rated current of the circuit-breakerb maximum short-circuit current at the point of installation - determines the breaking capacity.

Types of systemsEarthed systems Isolated systemsThe source has one earthed polarity (1) The source has an earthed mid-point

Comparison of series and parallel connection in terms of performance

Series connection of poles divides the voltage per pole and optimises breaking capacity for high-voltage systems.

Series connection of poles on a DC circuit breaker is the means to: b divide the system voltage by the number of polesb use the rated current for each poleb use the breaking capacity of the circuit breaker for all the poles.For example, a Compact NS630, 3P DC type, with the three poles connected in series, provides:b a maximum voltage of 750 V (250 V per pole)b a rated current of 630 Ab a breaking capacity of 100 kA / 750 V.Consequently, a 630 A / 250 V device can be used in a 750 V system.

Parallel connection of poles divides the current per pole and optimises the rated current for systems that do not exceed the withstand voltage of each pole.The maximum useable rating and the value of the magnetic setting are indicated on pages 110 and 111.

Parallel connection of poles, on the contrary, imposes the system voltage on each pole, but is the means to:b divide the current flowing through each pole by the number of polesb increase the rated current.For example, the same Compact NS630 DC 3P circuit breaker with three poles in parallel provides:b a maximum voltage of 250 V (250 V per pole)b a rated current of 1500 A (see table on page 111)b a breaking capacity of 100 kA / 250 V.Consequently, a 630 A device used in a 250 V system can handle 1500 A.

Calculation of the short-circuit current across the terminals of a batteryDuring a short-circuit, the battery discharges a current equal to

b Vb = maximum discharge voltage (battery 100 % charged)b Ri = internal resistance equivalent to all cells (a function of the capacity in ampere-hours).

Exampleb consider a set of four 500 Ah batteries connected in parallelb discharge voltage of one battery: 240 V (110 cells 2.2 V each)b discharge current of one battery: 300 A with a run-time of 30 minutesb discharge current of all four batteries: 1200 A with a run-time of 30 minutesb internal resistance 0.5 mΩ per cell, i.e. for one battery:Ri = 110 x 0.5 x 10-3 = 55 x 10-3 Ωb short-circuit current of one battery: Isc = 240 V / 55 x 10-3 Ω = 4.37 kAb neglecting the resistance of the connections, for all four batteries discharging the short-circuit current in parallel, the total short-circuit current is four times that of one battery, i.e. Isc = 4 x 4.37 kA = 17.5 kA.

Note: if the internal resistance is not known, it is possible to use the following rough approximation: Isc = kc where c is the capacity of the battery in ampere-hours and k is a coefficient close to 10 and always less than 20.

Other typical examplesb PABXs: Isc from 5 to 25 kA at 240 V DC with L/R = 5 msb submarine: Isc from 40 to 60 kA at 400 V DC with L/R = 5 ms.

L/R time constant

DB

1050

59

When a short-circuit occurs across the terminals of a DC circuit, the current rises from the load current (y In) to the short-circuit current Isc over a period of time that depends on the value of the resistance R and inductance L of the short-circuited loop.The equation determining the current in the loop is:u = Ri + L di/dtThe curve of I versus time is defined (neglecting In) by the equation:i = Isc (1 - exp(t/τ)) where τ = L/R is the time constant for the rise to Isc.Practically speaking, after a time t = 3τ, the short-circuit is considered to be established, because the value of exp(-3) = 0.05 is negligible compared to 1 (see the curve opposite).The lower the time constant (e.g. battery circuit), the shorter the time required for the current to rise to Isc.

To express breaking capacity, the interrupted short-circuit current with the following time constants is used:b L/R = 5 ms, fast short-circuitb L/R = 15 ms, standardised value used in standard IEC 60947-2b L/R = 30 ms, slow short-circuit.In general, the value of the system time constant is calculated under worst-case conditions, across the terminals of the generator.

Breaking-capacity values for:b Compact NS (table page 30) are the same for 5 ms and 15 msb Masterpact NW (table page 32) are indicated for 3 values, 5 ms, 15 ms and 30 ms.

Communication 0

COM option in Masterpact NW

The COM option is required for integration of the circuit breaker or switch-disconnector in a supervision system.Masterpact uses the Digipact or Modbus communications protocol for full compatibility with the SMS PowerLogic power-monitoring system. An external gateway is available for communication on other networks:b Profibusb Ethernet…

The COM option in Masterpact is made up of:

For fixed devicesb a "device" communication module, installed behind the Micrologic control unit and supplied with its set of sensors (OF, SDE ,PF and CH micro-contacts) and its kit for connection to XF and MX communicating voltage releases.

For drawout devicesb a "device" communication module, installed behind the Micrologic control unit and supplied with its set of sensors (OF, SDE, PF and CH micro-contacts) and its kit for connection to XF and MX communicating voltage releasesb a "chassis" communication module supplied separately with its set of sensors (CE, CD and CT contacts).Status indication by the COM option is independent of the device indication contacts. These contacts remain available for conventional uses.

Digipact or Modbus "device" communication moduleThis module is independent of the control unit. It receives and transmits information on the communication network.

Digipact or Modbus "chassis" communication moduleThis module is independent of the control unit. The Modbus "chassis" communication module makes it possible to address the chassis and to conserve the address when the circuit breaker is in the disconnected position. Consumption: 30 mA, 24 V.

XF and MX communicating voltage releasesThe XF and MX communicating voltage releases are equipped for connection to the "device" communication module.Remote-tripping functions (second MX or MN) are independent of the communication option. These releases are therefore not equipped for connection to the "device" communication module.

Communication with the circuit breaker Compact NS is possible using a number of hardware solutions:b Advantys OTB Modbus interface module with built-in inputs/outputsb SC150 interfaceb communicating auxiliary contacts.

A number of hardware solutions are available for the range:b Advantys OTB Modbus interface module with 12 inputs/8 outputs built in and expandable by adding optional modules from the Twido rangeb communicating auxiliariesThey replace the standard auxiliaries and connect directly to the Digipact bus, with three equipment levels:v communicating auxiliary contacts, comprising:- OF (on/off), SD (trip indication) and SDE (fault-trip indication) contacts- electronic module- prefabricated wiring.v communicating auxiliary contacts and motor-mechanism module, comprising:- OF (on/off), SD (trip indication) and SDE (fault-trip indication) contacts- MCH motor-mechanism module (220 V AC) (1)

- electronic module- prefabricated wiring.v communicating carriage switches for the chassis, comprising:- CE / CD (connected/disconnected position) contacts- electronic module- wiring connectorb SC150 interfaceUsing the SC150 interface, it is possible to integrate a device equipped with non-communicating auxiliaries into a supervison system.The SC150 interface is used to connect:v the auxiliary contacts on the circuit breaker (OF, SD, SDE, SDV, CD, CE)v the remote-operation system (on, off, reset) v one unassigned digital input.

SoftwareTo make use of the information provided by the communicating devices, it is necessary to use software incorporating a Modbus driver. Schneider Electric offers two solutions: the RCU utility and SMS software.

RCU utilityThis is a set of Modbus drivers that, in conjunction with a PC, can be used to:b view device status (on/off and fault trip)b view variables: currents, voltages, power, energy (instantaneous and maximum values)b remotely open and close the device.

SMS (System Management Software)SMS is power-management software to control and monitor LV and MV electrical installations.The SMS family includes a number of products offering different features for all types of applications.SMS can communicate with all intelligent devices in the electrical installation.

Common-point changeover contacts are used to remote circuit-breaker status information and can thus be used for indications, electrical locking, relaying, etc.They comply with the IEC 60947-5 international recommendation.

Functionsb OF (ON/OFF) - indicates the position of the circuit breaker contactsb SD (trip indication) - indicates that the circuit breaker has tripped due to:v an overloadv a short-circuitv an earth-leakage faultv operation of a voltage releasev operation of the "push to trip" buttonv disconnection when the device is ON.Returns to de-energised state when the circuit breaker is resetb SDE (fault indication) - indicates that the circuit breaker has tripped due to:v an overloadv a short-circuit.Returns to de-energised state when the circuit breaker is resetb CAM (early-make or early-break function) - indicates the position of the rotary handle. Used in particular for advanced opening of safety trip devices (early break) or to energise a control device prior to circuit-breaker closing (early make)b CE / CD (connected/disconnected position) - microswitch type carriage switches for withdrawable circuit breakers.

Installationb OF, SD and SDE functions - a single type of contact provides all these different indication functions, depending on where it is inserted in the device. The contacts clip into slots behind the front cover of the circuit breaker.The SDE function on a circuit breaker equipped with a thermal-magnetic trip unit requires the SDE actuator.b CAM function - the contact fits into the rotary-handle unit (direct or extended).b CE / CD (connected/disconnected) function - two parts must be fitted on the fixed and moving parts of the chassis.

Changeover contacts.

All the auxiliary contacts opposite are also available in "low-level" versions capable of switching very low loads (e.g. for the control of PLCs or electronic circuits).

MX or MN voltage releases are used to trip the circuit breaker.

MN undervoltage releaseThis release trips the circuit breaker when the control voltage drops below a tripping threshold:b tripping threshold between 0.35 and 0.7 times the rated voltageb circuit breaker closing is possible if the voltage exceeds 0.85 times the rated voltage. For a lower value, circuit breaker closing cannot be guaranteed.Circuit breaker tripping by an MN release meets the requirements of standard IEC 60947-2.

Time-delay unit for an MN releaseEliminates nuisance tripping due to transient voltage dips lasting 200 ms.It is used in conjunction with:b a 250 V DC MN release, control voltage 220/240 V ACb a 48 V DC MN release, control voltage 48 V AC.

MX shunt releaseTrips the circuit breaker when the control voltage rises above 0.7 x Un.Control signals can be of the impulse type (u 20 ms) or maintained.

OperationWhen the circuit breaker has been tripped by an MN or MX release, it must be reset locally.MN or MX tripping takes priority over manual closing.In the presence of a standing trip order, closing of the contacts, even temporary, is not possible.

Mechanical characteristicsb endurance is equal to 50 % of the mechanical endurance of the circuit breakerb the releases clip in behind the front coverb connection using wires up to 1.5 mm2, to integrated terminal blocks.

Wiring diagram of a point-to-point remote ON / OFF functionNote: An opening order always takes priority over a closing order.If opening and closing orders occur simultaneously, the mechanism discharges without any movement of the main contacts. The circuit breaker remains in the open position (OFF).In the event of maintained opening and closing orders, the standard mechanism provides an anti-pumping function by blocking the main contacts in open position.Anti-pumping function. After fault tripping or intentional opening using the manual or electrical controls, the closing order must first be discontinued, then reactivated to close the circuit breaker.When the automatic reset after fault trip (RAR) option is installed, to avoid pumping following a fault trip, the automatic control system must take into account the information supplied by the circuit breaker before issuing a new closing order or blocking the circuit breaker in the open position.

Electric motor (MCH) for Masterpact NW.

XF and MX voltage releases.

"Ready to close" contacts (PF).

Electric motor (MCH)The electric motor automatically charges and recharges the spring mechanism when the circuit breaker is closed. Instantaneous reclosing of the breaker is thus possible following opening. The spring-mechanism charging handle is used only as a backup if auxiliary power is absent.The electric motor (MCH) is equipped as standard with a limit switch contact (CH) that signals the "charged" position of the mechanism (springs charged).

Voltage releases (XF and MX)Their supply can be maintained or automatically disconnected.

Closing release (XF)The XF release remotely closes the circuit breaker if the spring mechanism is charged.

Opening release (MX)The MX release instantaneously opens the circuit breaker when energised. It locks the circuit breaker in OFF position if the order is maintained (except for MX "communicating" releases).

Note: whether the operating order is maintained or automatically disconnected (pulse-type), XF or MX "communicating" releases ("bus" solution with "COM" communication option) always have an impulse-type action.

Electrical closing pushbutton (BPFE)Located on the front panel, this pushbutton carries out electrical closing of the circuit breaker. It is generally associated with the transparent cover that protects access to the closing pushbutton.Electrical closing via the BPFE pushbutton takes into account all the safety functions that are part of the control/monitoring system of the installation.The BPFE connects to the closing release (XF) in place of the COM module.

This function opens the circuit breaker via an electrical order. It is made up of:b a shunt release (second MX)b or an undervoltage release (MN)b or a delayed undervoltage release (MN + delay unit).These releases (2nd MX or MN) cannot be operated by the communication bus.The delay unit, installed outside the circuit breaker, may be disabled by an emergency OFF button to obtain instantaneous opening of the circuit breaker.

MX or MN voltage release. Circuit-breaker response time at Un 50 ms ±10

Instantaneous voltage releases (MN)The MN release instantaneously opens the circuit breaker when its supply voltage drops to a value between 35 % and 70 % of its rated voltage. If there is no supply on the release, it is impossible to close the circuit breaker, either manually or electrically. Any attempt to close the circuit breaker has no effect on the main contacts. Circuit-breaker closing is enabled again when the supply voltage of the release returns to 85 % of its rated value.
