概述 Overview

VGP-40.5 ( ZN85 ) 型户内高压真空断路器，适用于三相交流 50Hz, 额定电压 40.5kV 电力系统中，可供工矿企业、发电厂及变电站作为分合负荷电流、过载电流、
故障电流之用。
断路器是与操动机构采用上下布置结构，有效地降低了断路器的深度。
最新小型柜
为这种新型断路器专门设计的弹簧操动机构，安装在断路器框架内，其结构特点更适合断路器的上下布置形式，并成为断路器整体结构中不可分割的一部分，
机构设计简单，输出曲线及其性能更适合 40.5kV 真空断路器的特点和要求。
该断路器适用于频率操作及多种场合和运行条件比较苛刻的场所。
VGP-40.5 ( ZN85 ) indoor high voltage vacuum circuit breaker, suitable for three-phase AC 50Hz, rated voltage 40.5kV power system for industrial and mining
enterprises, power plants and substations as a separate load current, overload current, fault current Use.
The circuit breaker is equipped with the upper and lower arrangement with the operating mechanism, effectively reducing the depth of the circuit breaker.
品牌授权柜
The spring operating mechanism specially designed for this new type of circuit breaker is installed in the frame of the circuit breaker, and its structural features are GE
more suitable for the upper and lower arrangement of the circuit breaker and become an integral part of the overall structure of the circuit breaker. The design of
the machine is simple, the output curve and its performance are more suitable for the characteristics and requirements of 40.5kV vacuum circuit breaker.
The circuit breaker for frequency operation and a variety of occasions and operating conditions more harsh places.
