2.Product Features

2.1 Stable, reliable and endurable

The biasing arc-suppression coli is of a completely static strycture  without any moving parts inside, featuring a long service life. The controller is controlled by a computer, with the electromagnetic compatibility index up to class IV,so it is stable and reliable.

2.2Higher regulation precision and fast response

  The computer can instantly monitor the grid capacitor current featuring high accuracy, the core magnetic permeability can be changed by means of applying DC excitation current,and the reactance value can be adjusted in the millisecond level with live high voltage, which features fast response ,with the compensation response time no more than 20ms.

2.3Dynamic compensation, with damping resistors not required

The automatic tracking dynamic compensation is adopted to have the compensation resonance suppression less than 5%after a single phase is grounded, which has fundamentally eliminated the seies resonant over-voltage in the compensation system with no additional damping resistors needed,so there is no resistance collapse or burning due to control dead zone.

2.4Electric controlled  stepless continuous and static adjustability

   The biasing arc-suppression coil can apply DC exciation current to change the core magnetic permeability so as to change the reactance value of the arc-suppression coil, and adjust the inductance value at the power speed according to a certain measurement and calculation curve in case of live high voltage,so there is no tap and stepless ,continuous and static adjustment can be achieved.

2.5Simple structure ,space-saving ,low failure rate,easy maintenance and basically free of maintenance

   Compared with traditional loop and capacitance-tuning arc-suppression coils ,it only had one side equipped with grounding transformer, arc-suppression coil, wall-penetration bushing, isolation switches and other auxiliary devices ,and all tuning and operating tasks are to be completed by the control system, which had reduced the fault points of such equipment as load switches, damping cabinets and capacitor banks ,as well as maintenance work ,to have basically achieve maintenance-free effect.

3.Structure:

  The THT-PXHK biasing magnetic arc-suppression coil automatic tracking compensation control system consists of the following three parts:

Grounding transformer ,biasing magnetic arc-suppression coil and computer control cabinet ,in which the grounding transformer and arc-suppression coil can be dry type or oil-immersed ,and the computer control cabinet had standard careen body,on which automatic tracking compensation controller ,instrument panel and rectifier devices are equipped,with the shape as shown in figure3.
