Product Description
Indoor 24kV High-voltage Fixed Type Circuit Breakers of Vs1

Indoor 24kv High-Voltage Fixed Type Circuit Breakers of Vs1 Series

Product Overview


VS1
(ZN63A) series vacuum breaker is of indoor high voltage switchgear suitable for 12kV .Three-phase power system with 50Hz frequency in order to protect and control electrical appliances, and especially suitable for frequent operation at rated current or incessant open circuit due to unique advantages of vacuum circuit breaker.
Spring operating mechanism and breaker body parts adopt integration design. Thank for this design, breaker not only can be a fixed installation unit, but also can be a withdraw-able unit with a specially pushing framework. For meet the requirement of XGN2, GG1A cabinet, the fixed type breaker can be install additionally interlock.

Special Operating Condition

Please consult with manufacturer on manufacturing technology when operating environment is the climatic environment with high altitude, high humidity and great temperature change or other special environment condition.
 
Packaging, Transportation and Storage Precautions

(1) Circuit breaker should be in the state of opening and energy storage spring in a state without energy storage when packing. It should be in the state of opening and energy storage spring in a state without energy storage when packing. And it should be fixed on the bottom of the wooden case, should have waterproof measures and complete package labels.
(2) Circuit breakers can't invert and avoid strong vibration, rain, surface damage, and components lost when transportation.
(3) When loading the circuit breaker, we suggest the following tools: crane, forklift and driving. When lifting the circuit breaker, we should not hook on the body or pole of the circuit breaker, but on the lifting hole which has the lifting mark.
(4) When circuit breaker has a long-term storage, it should be in a state of opening and energy storage spring in a state without energy storage and placed in dry ventilated indoor preventing from moisture, vibration control and harmful gas erosion, and regularly checked whether environment meets the requirements.
(5)When first use products after long-term storage, it need to have a power frequency withstand voltage insulation testing.
