The recloser is a high-voltage switchgear with self controlled protection function that can automatically perform disconnection and reclosing operations in the AC line according to the predetermined disconnection and reclosing sequence, and automatically reset or lock afterwards.
Product details
summary:
ZW32-12F outdoor high-voltage vacuum circuit breaker is used in three-phase distribution network systems with AC 50Hz and voltage of 12KV. The recloser is a high-voltage switchgear with self controlled protection function that can automatically perform disconnection and reclosing operations in the AC line according to the predetermined disconnection and reclosing sequence, and automatically reset or lock afterwards. It can achieve distribution automation without relying on additional control systems. This system can quickly segment and isolate faults, reduce the power outage range to a smaller size, and is the primary equipment for urban and rural power grid transformation. The recloser can be equipped with isolation switches according to user requirements.
This circuit breaker requires a voltage transformer.
Structural features:
◆ High sealing performance three-phase pillar fully enclosed structure:
◇ Stable and reliable breaking performance, without combustion and explosion hazards; Maintenance free, small size, light weight, long service life;
