Product Overview
The ZW6C-12 series vacuum circuit breaker is a high-voltage outdoor switchgear with a rated voltage of 12KV, three-phase AC 50HZ, and single-phase grounding protection function,
It is mainly used to disconnect and close the load current, overload current, and short-circuit current of rural power grids, urban power grids, and small power systems. The overall structure of this product is a three-phase common box, with a three-phase vacuum arc extinguishing chamber placed inside a metal box. It uses SMC insulation material for phase insulation and ground insulation, with reliable performance and high insulation strength. Smart circuit breaker of the breaker type. The basic type and coincidence controller are suitable for easily accessible power supply situations, the PT type and coincidence controller are suitable for situations without power supply, and the intelligent circuit breaker is suitable for radiation power supply and ring network power supply systems, helping the system eliminate instantaneous faults, automatically restore power supply, and also isolate permanent faults to achieve distribution network automation.
The intelligent circuit breaker has 1-3 reclosing functions, and the recloser parameters can be set;
The intelligent circuit breaker has the functions of closing surge control, overcurrent protection, and short-circuit quick break three-stage composite protection, and the parameters can be continuously set;
Intelligent circuit breakers have low current grounding protection function and parameters can be continuously set;
Intelligent circuit breakers can achieve wired remote control or wireless remote control under the pole. Used for three-phase power systems with AC frequency of 50Hz and voltage of 10-12kV, it is used for breaking and closing load currents. It has overload and short circuit protection functions, quick break protection functions, timed delay protection functions, automatic reclosing functions, and can also be equipped with lightning arresters or isolation switches according to user needs, that is, a combination of circuit breakers and isolation switches, hereinafter referred to as "combination intelligent circuit breakers" This intelligent circuit breaker comes with its own power supply, can be remotely operated nearby, and is equipped with CT and PT interfaces to meet telemetry requirements
