Product description
Parameters

The arc suppression coil is the single-phase reactor which is adjustable with electrical inductance. When it is under the multi-tap model, the capacity of the compensating current can be changed through the control of the inserted tapping point position with the on-load switch; and when it is under the tuning capacitor condition, the inductance current of the main winding can be adjusted through the change of the capacitance in the low-voltage winding of the arc suppression coil. The arc suppression coil is equipped with the secondary winding to be inserted into the damping resistance.

● Product Model and Performance Parameter

Product Model

Performance Parameter

XDZC and XDCR Dry-type Series

The voltage class is 6~35kV and the rated capacity is 27~4200kvar

XDZJ and XDJR Oil-immersed Series

The voltage class is 6~66kV and the rated capacity is 27~6500kvar

● Technology Feature

The dry-type series adopt the epoxy cast insulation system with no oil medium and excellent safety. The class of the coil for insulation and heat resistance is F, and the coil is casted into a solid entirety; the oil-immersed series iron eddy current is provided with small loss, low noise, and small volume, which can be used out of door with strong acclimatization ability. It takes the lead domestically.

 

 

● Application Scope

When the single-phase ground fault takes place in the three-phase electrical power system, the inductance current will be generated in the arc suppression coil to offset the capacitance current caused by the ground capacitance of the line, eliminating the continuous arc of the fault point due to the existence of the capacitance current, avoiding the expansion of the fault scope and improving the safety and reliability of the power supply system. It is suitable to the isolated neutral system with the voltage class of 6~66kV nationwide and under 33kV abroad.
