There are many equipments with rapid and frequent load changes in the industry. However, AC contactors can not meet the immediate needs of the reactive power switching of the system, thus thyristor fast compensation switching device that adopts the operational concept of "zero-crossing switching" can be applied, which can realize the fast switching without inrush current and arcing to reduce the interferece of inductive reactive power on the power grid.
KLD-TSC series thyristor switch is characterized by no mechanical wear and tear and no noise during operation, and has the advantage of practically no transient process. It means that the equipment has the smallest delay for power factor improvement and the control system ensures the capacitor banks of all segments switch on or off in the shortest time of only one cycle.
It is mainly applied to fast and frequent changes in reactive power, and scenarios with inrush current limit and voltage fluctuations. The product has built-in thermal protection, and LED indicators for switching display.
No inrush current for zero-crossing switching, built-in over-temperature protection, frequent switching, no noise, integrated and convenient installation, fully sturdy and durable cast structure, automatic start/stop built-in cooling fan, display of the switching status by LED indicator.
Bolt type push-in fixation
Combined with SC type cable lug for connection
Fixed with 8mm Allen wrench
It is recommended that torque should not exceed 15N.M
Three-phase thyristor switch adheres to the principle of 2 controls and 3 switchings, thus phase B will not be converted, and each phase of the switch can be controlled independently to realize single-phase compensation.
