Scope: Auto-switching tunable filter cabinet for a more stable load change, the harmonic content of relatively small power system

For industry:

1 apply to rapidly changing loads: such as iron and steel industry, welding machine load and the industry that using elevators, driving.

2 thyristor switching tuned filter with fast switching capability can be used to support the distribution system voltage , improvement of load power factor.

3 thyristor switches have no mechanical wear, operation with no noise, and has advantages of no transient .

4 The control signals can be sent directly from the load to the tuning filter, which means that the power factor improvement with minimal delay.

5 control system make the minimal time of and removal of the tuning filter only be *0ms in all segments
6 Each tuning filter consists of a capacitor and a reactor in series, the two components form a series resonant circuit, the resonant frequency below the lowest harmonic frequency present in the system (such as **0Hz, **0Hz).

7 choice of tuning filter depends on the control requirement , and in accordance with the required amount of reactive power compensation and load types, the load can be symmetric or asymmetric, can also be connected to the linear-voltage or phase-voltage.

8 In order to make power factor correction of high-speed welding machine achieve the best possible results, the control signal directly sended from the welding machine to the tuning filter, the tuning filter power factor compensation is based on the needs of reactive power.
