概述 Overview

ZN85-40.5/T2000-31.5型户内 高压真空断路器(以下简称断路器),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 与操作机构采用上下布置结构,有效地 降低了断路器的深度。三相灭 弧室和相联带电体由三只独立的环氧树脂绝缘筒相隔离,构成复合绝缘结构,断路器 满足正常运行条件下的空气距和爬电距要求,并有效 地减小了断路器的体积。主导电 回路真空灭弧室和动静导电联接安装在绝缘筒内,使相间距仅为300mm。主回路 电气连接全部采用固定式连接,具有很高的可靠性。绝缘筒 安装在断路器框架上方。

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 特点更适合真空断路器上下布置形式,关成为断路器
整体结 构中不可分割的一部分。机构设计简单,输出曲线更适合40.5KV真空断 路器的特点和要求。

总体布局合理、美观、简洁。体积小巧、操作灵活,具有电气性能可靠、使用寿命长、检修方便、机构免维护的特点。该断路 器适用频繁操作及多种场合和运行条件比较苛刻的场所。

 ZN85-40.5/T2000-31.5 type indoor high voltage Vacuum circuit breaker (below said as VCB), is suitable for power system
with 3-phase AC 50HZ, rated voltage 40.5KV, it can be used as load current, overload current and fault current for mining
enterprises, power plant and substation.

The breaker and the operation structure is upper and lower layout, reduced the depth effectively.3-phase interrupter and associated live parts are isolated by three independent isolated epoxy insulating tube, act as the
composite insulation structure. This VCB can meet the requirement of air distance and creepage distance, and reduce the size of the VCB effectively. Leading electric circuit interrupter, static and dynamic conductive connection install in the insulating
tube which let the distance between the phase is only 300mm. All the leading electric circuit is fixed type, which makes the
connection very stably. Insulating tube install on the upside of the frame.The spring actuator specially designed for this type of new VCB, install inside of the frame, which  is more suitable for the
upper and lower structure, as an inseparable part of the VCB. The design of the VCB is simple, output curve is more suitable for the features and requirements f the 40.5KV VCB.

Overall layout is reasonable, beautiful, simple, with features as smaller volume, flexible operation, reliable characteristics,
long endurance life, easier inspection, free of maintenance, etc. It is suitable for frequently operation, suitable for the places in very poor condition.
