Thyristor Switched Capacitor system is designed for 0.4kV low voltage distribution network. It mainly includes the Thyristor Switches, Capacitors and Reactors, using as a new generation of compensation module with functions of energy saving, reduction of line loss, power factor enhancement and improvement of power quality.
LBT series dynamic switching unit refers to a kind of contactless rapid switch with high reliability, and it is used in dynamic power factor compensation equipment. It is especially applicable to switching occasions requiring rapid and no-wear switching. It is usually applied into occasions where reactive change is frequent, such as lifting equipment, elevator and electric welding machine.
