Abstract: Introduction was made to the structure and working principle of XHDCZ type arc-suppression coil. This paper expounded two cases of XHDCZ type arc-suppression coil faults, the site disposal method and the cause the fault occurring. Aiming at the problems existing in arc-suppression coil running, this paper presented some countermeasures, which means to guide a pass better when the equipment is checked and accepted. The products should be strictly installed and the improvement of damping resistance and its control circuit is still the key point of arcsuppression coil grounding system.
Key words: arc-suppression coil; damping resistance; protection unit; silicon controlled; piezoresistor
