3. Operation manual

3.1. Operation description

Fig. 3.1.1 The simplified logic diagram of MAP 6

The main functional elements are mapped at a simplified logic diagram: 6 optical inputs and one optical out-put, 2 binary inputs and 2 binary outputs, TRIP and LOCK diodes. Optical sensors or outputs of another MAP6 devices can be connected to 6 optical inputs of device and all this signals will be summed. Logical summ is given to a fiber output and through memory area (it is not showed on pic. 3.1.1) to high rated power relay output (DO_1) and TRIP diode. Further signals from OI_1, OI_2 i OI_3 are summed using three-input system of auxiliary logical sum, and this sum is given to binary output DO_2. Signals of binary input block optical signals, and this state is signalling by LOCK diode. Protection tripping is signalling by continous light of TRIP diode and activating DO_1 relay output in 5s. This signal is repead every 1s, until the optical inputs are disactivated. If protection is activated by optical signal from IO_1, IO_2 or IO_3 input, also output DO_2 will be activated until multifunctional button will be pressed.

Reduction of supply voltage causes the reset of the device state and deactivation of the out-put relays. If the reduction of supply voltage occurred when TRIP signaling and relay output DO_2 were activated, then TRIP signaling and relay output will be restored after the reload of power supply.


3.2. Application examples

3.2.1. Circuit-breaker bay

Connection diagram of MAP 6 in switchgear bay equipped with circuit-breaker. 6 optical sensors are used, 2 in each bay: busbar bay, circuit-breaker bay and terminals bay. One of relay output can be connected directly to the breaker. Optional, second output can be connected to control bay device, for redundant protection and proper information about tripping by the bay control device. For example this configuration can be used in feeder bay, where opening of the circuit breaker cuts off an arc current. One of the optical inputs can be also used to connect the MAP 6 device placed in another bay, where opening of the circuit breaker does not cut off an arc current.

Fig. 3.2.1.1 Connection of MAP 6 in circuit-breaker bay

If you connect device as shown in Fig.3.2.1.2, you can adapt additional criteria of interlock for arc protection. In that case you should not connect MAP 6 device with bay control unit directly. Instead of this optical output of MAP 6 should be connected with optical input of bay control device and arc protection algorithm should be activated with additional criteria. This solution allows use much more optical sensors than using only of con-trol device.

Fig. 3.2.1.2 The insertion of additional criteria for arc protection


3.2.2. Arc protection with additional criteria

If you use external relays measuring voltage U < connected to the digital inputs, you can improve the selectiv-ity of security and adapt additional criteria for arc protection. Connection diagram for this configuration is shown in Fig. 3.2.2.1. An alternative way of implement an additional criteria using the bay control device with arc protection algorithm is described in section 3.2.1.

Fig. 3.2.2.1 The insertion of additional criteria for arc protection

3.2.3. Cascade connection

MAP 6 can be used to combine signals from many optical sensors. This is useful when many signals from opti-cal sensors need be passed for superior circuit-breaker bay. By using the MAP 6 signals from one bay may be added together and pass for the next bay by a single fiber optic cable, where they are summed with the sig-nals from sensors installed in this bay and via MAP 6 are forwarded in the direction of the circuit breaker bay. This configuration is named the cascade connection. This is possible thanks to a very small time of propaga-tion of the optical signal from the optical input to the optical output, which does not exceed 12 µs. Addition even of a few propagation times can give a totally negligible time delay of the transmission of information about activation even a distant optical sensor. This is a competitive solution compared to systems based on connections using communication buses. MAP 6 may be pre-installed with optical sensors in the modular and prefabricated switchgears, which mini-mizes the time required to make connections during launch of switchgear. This solution reduces arc protec-tion wiring tracks to individual optical connections between adjacent bays. Example of application of the MAP 6 devices for arc protection the switchgear with four bays is shown in fig. 6. Four cascade connected devices collect signals from 20 optical sensors. The sum of this signals is putted to the bay control unit in the supply bay. Locally in each bay, if arc fault is detected by sensors connected to one of six inputs, signal from DO_1 output is brought to own breaker, which can be open immediately. In this case, the opening of the local circuit breaker effectively cuts off the arc supply current without opening the circuit breaker in the supply bay. Therefore, minimum delay of operation of the arc protection algorithm is necessary. This delay is entered naturally with the use of additional criteria U < , because voltage measure-ments is needed to done. The illustrated configuration of devices allows to realize progressive arc protection and causes a selectivity of this protection.

3.3. Diagnostic

3.3.1. DOC – Device Operation Check

MAP 6 device is equipped with a mechanism to facilitate the control of the device operation (DOC - Device Operation Check) and correctness of fiber optic connections.

Holding the button for 5 seconds starts the DOC mechanism. Switching to operation check mode is confirmed by a LED TEST. Square wave a 1 Hz frequency is generated at the outputs DO_1, DO_2 and OO_1 in control mode. The beat of this signal turns on and off the TRIP diode. The testing signal allows also to check fiber cascading connec-tions. Ending check mode occurs automatically after 15 seconds.
