static switching modules unit
DESCRIPTION
1. The static switching modules of the JK3PSZT series are the basic building block for the construction of static capacitor banks for power factor correction purposes. These capacitor banks use thyristors instead of the classic contactors for the connection of each large group of capacitors and they are ideal in installations where the leakage current suffers quick and large fluctuations (load changes in intervals that can range from split seconds to 8 or 10 seconds). 2. The static switching units of the JK3PSZT Series have been designed to connect and disconnect capacitors in milliseconds. They can be used to build capacitors with various steps, or for the individual compensation of a load that must be compensated instantly due to connection / disconnection deficiencies, for example, in welding units, cranes, lifts, etc.TRANSCRIPT

The all series capacitor banks with staticsystem have been designed for Powerfactor correction purposes innetworks with fluctuating loads.
The variations in power are relativelyfast (in milliseconds) so that the switchingoperations are carried out by thyristors,which are connected to a voltage controlboard, so that the connection anddisconnection of the capacitor is carriedout with a zero voltage difference.
Transients are prevented between theconnection and disconnection of steps,obtaining the immediate response to theload fluctuations.
Functions and advantages of capacitorbanks with a static system
The functions or advantages of thiscompensation system are as follows:
Immediate response to the compensationrequest. The response time of the Powerfactor correction can be of a single networkfrequency cycle, thus achieving an almostinstantaneous compensation.
Elimination of start-up transients produc-ed by the capacitor's connection. The conn-ection takes place when the voltage networkmatches that of the capacitor when it is par-tially or totally loaded.
The lack of transients in the connection allo-ws us to eliminate gaps, flicker and any otheralteration generated by the connection's tran-sient.
Limited switching operations
Lower wear of capacitors and switching elem-ents, due to the elimination of transients andthe total absence of mobile mechanical parts.This is how we can greatly increase the work-ing life of the unit, as compared to conventio-nal electromechanical contactor units.
Connection of a static capacitor bankStatic capacitor banks are usually connectedto the general switchboard or secondary swit-chboards in the case of large-scale installatio-ns.
