Matching ZN12 ZN68A types of VCB CT68 Spring Operating Mechanism for High Voltage Electrical Equipme

Description

Product Description
CT68 Vacuum Circuit Breaker Operating Mechanism

General
1.1 Type CT68-12、CT68-40.5 spring operating mechanism match ZN12-12、ZN12-40.5 and ZN68-12 indoor high voltage VCB.
1.2 It is spring energy storage operating mechanism. It can be operated by AC, DC or manual.
1.3 The circuit breaker that the mechanism matches adopts special contact material and interrupter with high breaking capacity and with very long electrical endurance.
1.4 The circuit breaker has simple structure, high breaking capacity, long endurance, all-round operating functions, no explosive danger and convenient maintenance. It is fit to control transport system and protect switch in powerhouse and transformer substation, especially fit to break important load or frequent operations in some places.

Condition of service:
1.Height above sea level: not exceed 1000M.
2.Circumstance humidity: max +40℃, min -25℃.
3.Relative humidity: daily average≯95%, monthly average 90%.
4.Earthquake intensity: Degree 9.
5.Installation place: no fire, no explosive danger, no serious corrosion, and no frequent tense vibration.
 
Technical features:
1.The modular functional units are designed in a rational structural layout and it is convenience In manufacture and maintenance.
2.The operating mechanism is developed specially for the domestic complicated weather conditions.
3. It is an enhanced operating mechanism for the users who needs high voltage and large capacity.
4. 27.5KV spring operating mechanism and circuit breaker assembly are for 63KA breaking generator protection circuit breaker.
 
Products with special requirements, specifications and dimensions that need to be improved can be designed and manufactured according to user requirements.
