Outdoor AC vacuum circuit breaker is used to make and break load current, overload current and short-circuit current in 12kV,50/60Hz power system. It's applicable for substations, industry and mining, urban and rural electricity power networks, especially applicable in occasions with frequent operation and automatic power distribution network. It accords with the standards of IEC62271-100 &GB1984 AC high voltage circuit breaker, GB/T 11022 HV General technical requirement of switches and control apparatus.
Ambient Temperature:-40ºC~+40ºC
Altitude:≤2000m
Wind Pressure: no more than 700Pa (equal to 34m/s wind speed
Maximum Temperature Drop: no more than 25ºC
There will be have dew under the condition of high temperature low down hastily.
The use of silicone rubber tube, so that the insulation distance between terminals is sufficient, the external insulation characteristics are excellent.
It can be matched with the controller to realize remote control, telemetry, remote signal and rolling, and realize the "four remote" function
Operating mechanism of newly designed small electric spring mechanism
An explosion-proof device is installed on the top of the box
