Product Detailed
ZN85 indoor high voltage handcart type vacuum circuit breaker 1.High quality, competitive price 2.Certification: ISO9001

ZN85 indoor high voltage handcart type vacuum circuit breaker

1.General

ZN85-40.5 type indoor high voltage vacuum circuit breaker is appropriate to 40.5kv,50Hz threephase current system, applicable to break loading current ,over load current ,fault current inmining industrial enterprise, power station, transformer substation. The layout of circuit breakerand operating mechanism are assembled up and down, which reduced the depth of circuit breakereffectively. Three poles interrupter and jointed charged body are isolated by epoxy resin insulator.This composite isolate structure meets the requirement of air and creepage distance and decreasedthe circuit breaker volume. Main conductive circuit ,vacuum interrupter, moving and fixedconductive joint are mounted in the cylinder, which makes the distance of each pole is only300mm.Main circuit electrical joints are reliable all fixed joint. Specialized designed springoperating structure is fixed in the frame of circuit breaker. This simple design makes the outputcurve and performance greatly matches to 40.5kv circuit breaker. The overall layout is reasonable,simple and free of maintain. It can be used in frequent and harsh operating condition.

2. Ambient conditionAmbient temperature: max +40°C min -15°C(conveyance under -30°C is allowed)Altitude: ≤1000mRelative humidity: daily average relative humidity: ≤95%; monthly average relativehumidity≤90%, daily average saturated vapor pressure ≤2.2*10-3 MPa,monthly averagevalue ≤1.8*10-3 MPaEarthquake intensity: ≤8 degreeThe installation should be free from fire, explosion, severe vibration, chemical corrosion andserious pollution
