Technical Specification
Structure characteristic>>ZW8-12/T type outdoor high voltage vacuum circuit breaker
ZW8-12/T type outdoor high voltage vacuum circuit breaker is ZW8-12 series commom type. ZW8-12/T equipped with spring operating mechanism, with function of break and close the load current, over load current and short circuit current, etc. Circuit breaker equipped with disconnector can be composed of combined circuit breaker which has obvious fracture (hereinafter referred to as the "combination of circuit breaker"). The isolating switch adopts silicon rubber insulation jacket, the jacket has the characteristics of anti-wind, rain, snow, sand, dirt corrosion, can effectively prevent the isolation switch frozen and oxidation. The breaker can be equipped with the lightning arrester, the arrester according to user requirements can be installed in the inlet, either outlet side; The circuit breaker can be equipped with inrush current controller, which can equipped it with eliminate inrush current and over current function; The circuit breaker can be installed 2~3 pieces of measuring transformer.
>>ZW8-12/C type outdoor high voltage vacuum circuit breaker
ZW8-12/C type outdoor high voltage vacuum circuit breaker has all the functions of the basic type circuit breaker, equipped with recloser controller to comprise of recloser intelligent circuit breaker. The basic type and recloser controller equipped is suitable for easy taking power supply occasions. PT and recloser controller equipped is suitable for occasions without power supply. Intelligent circuit breaker is suitable for power supply system of radial power supply and ring power supply system, help system to eliminate the transient fault, automatic recovery of power supply, also can isolate the permanent fault, realize distribution automation. Intelligent circuit breaker with 1~3 times reclosing function, and parameters can be set; Intelligent circuit breaker with close inrush current control, over current protection and short circuit fast breaking three composite protection function, and parameters can be continuous tuning; Intelligent circuit breaker has the function of small current grounding protection, and the parameters can be continuously tuning; Intelligent circuit breaker can realize the wired remote control, also can be wireless remote control under the rod.
>>ZW8-12/PT type outdoor high voltage vacuum circuit breaker
ZW8-12/PT type outdoor high voltage vacuum circuit breaker has all the functions of the basic type circuit breaker, this circuit breaker is equipped with voltage transformer. Voltage transformer take power from the high voltage side of the line, according to the need to provide 220V, 110V, 100V voltage for itself or other control device; The circuit breaker (small hydropower type) can be used to monitor the line voltage, when over-voltage or under voltage, the controller automatically disconnect the circuit breaker, and can be widely used for small hydropower and main grid grid connected branch, realize the automatic isolation of fault and network monitoring; The circuit breaker (measurement type) can output 0.2 level accuracy voltage, current signal, is the ideal choice for rural substation, outside the station point switch and simple measurement switch.
>>ZW8-12/ electron PT type outdoor high voltage vacuum circuit breaker
ZW8-12/ electron PT type outdoor high voltage vacuum circuit breaker has all the functions of the basic type circuit breaker. The circuit breaker equipped with electronic PT, take power from CT to charge the battery, under the loss of voltage can be carried out multiple energy storage and on-off operation, and can provide the working voltage for external equipment; having close inrush current control, over current protection and short circuit fast breaking three composite protection, protection parameters can be set by user; not only can realize the wired remote control, also can be wireless remote control under the rod.
