KLD-TSC Series

Thyristor Switch

Thyristor switching switch can respond in real time to the rapidly changing reactive power demand, and the zero-crossing switching function protects the compensation components.

PRODUCT OVERVIEW

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.

FAST ZERO-CROSSING SWITCHING WITH
BUILT-IN OVER-TEMPERATURE PROTECTION FUNCTION

Integrated structure makes the installation process more convenient,
and over-temperature protection function makes the use more safe.

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.

Integrated structure

Integrated assembly, small size, easy for installation, maintaineance and replacement.

Advanced technology

Zero-crossing switching mode avoids the impact of surge on the system, realizing fast and frequent switching in 1-20ms.

Status indication

LED indicates the switching status and visualizes the operation status.

Self-protection function

Built-in over-temperature protection function, and it automatically cuts off when the temperature exceeds 80℃.

BOLT TYPE PUSH-IN WIRING

Combined with SC type cable lug to make the
connection between primary conductor and switch more tight and secure.


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

SUPERIOR HEAT DISSIPATION PERFORMANCE

Integrated cooling fan with automatic start/stop function, along with the large aluminum alloy cooling base, accelerates the heat dissipation process.

MEET DIFFERENT COMPENSATION
REQUIREMENTS

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.
