ZN85-40.5 Indoor High Voltage Vacuum Circuit Breaker

Main Application

ZN85-40.5/T2000-315 type indoor high voltage vacuum circuit breaker (hereinafter referred to as circuit breaker), is applicable to three-phase ac 50 Hz, rated voltage 40.5 kV power system, available for industrial and mining enterprises, power plants and transformer substations as points and load current, overload current and fault current.

Circuit breaker and operating mechanism arranged up and down the body, effectively reduced the depth of the circuit breaker. Three-phase arc extinguish chamber and the associated charged body consists of three isolated root epoxy insulating tube, a composite structure, under the condition of normal operation of circuit breaker in meet the air distance and the creepage distance requirements, and effectively reduce the volume of circuit breaker, main electric circuit of vacuum arcing chamber and electrostatic conductive connection installed within the insulation cylinder, make phase spacing is 300 mm,The main circuit electrical connection adopts fixed connection, high reliability,insulation pipe installed in the breaker frame above. The overall layout is reasonable, beautiful and concise.Small size, flexible operation,reliable electrical performance, long service life, easy maintenance, convenient maintenance mechanism.

The circuit breaker is suitable for frequent operation and all kinds of bad operating conditions.

Main feature

1.the use of screw feed mechanism, labor-saving, stable, good self-locking performance.

2.Small size,flexible operation,reliable electrical performance,long service life, convenient maintenance, fewer times of maintenance.

Operating mechanism

1.ZN85 vacuum circuit breaker is an integrated 3AV3 spring operation mechanism, which is relatively mature,stable and reliable.

2.mechanism design is simple, the output curve and its performance is more suitable for the characteristics and requirement of 40.5 kV vacuum circuit breaker.

Installation

1.ZN85 vacuum circuit breaker installed in the switching cabinet can be fixed type,can also be drawn out type, with good adsorption
