Product Description:
LW3-12, LW3-12G I II I series outdoor high-voltage sulfur hexafluoride circuit breaker is a new type of outdoor high-voltage electrical appliance with sulfur hexafluoride gas as the interrupter and insulation medium. The operating mechanism is divided into (type 1) manual energy storage spring operating mechanism. (Type I) electric motor energy storage spring operating mechanism, (1] type) three types of DC electromagnetic operating mechanism, all kinds of operating mechanisms and the circuit breaker body are perfectly combined into a whole. Compared with other 10KV class outdoor circuit breakers, this product has obvious advantages such as simple structure, excellent arc extinguishing and insulation performance, small operating power, high rated parameters, long electrical life and non-maintenance period. The use of this product can not only reduce the occupied area, reduce the construction cost and eliminate the risk of fire, but also greatly improve the reliability of the power system. The circuit breaker has all the functions of the basic circuit breaker, and the recloser (or sectionalizer) type intelligent circuit breaker is formed when it is combined with a recloser controller or a section controller. Cooperating with T and reclosing controller (section controller), it has three-stage composite protection of closing inrush current control, overcurrent protection and short circuit quick break, 1-3 times of reclosing, small current grounding protection, wired remote control, and can also be used in Multiple functions such as wireless remote control under the pole, and the controller parameters can be continuously adjusted. It is an ideal choice for rural power substations, scattered point switches outside stations and simple metering switches.
