Primary and secondary fusion complete sets of vacuum circuit breaker requirements:
1, The primary and secondary fusion complete set of circuit breaker consists of switch body, feeder terminal, power supply voltage transformer (or capacitance pickup module), voltage transformer, current transformer , connecting cable and so on.
2. The switch body, feeder terminals, and power supply voltage transformer are connected with aviation connectors through outdoor type fully insulated cables. The aviation socket exposed to the air must be sealed with sealing material for the metal conductor to improve its anti-condensation performance.
3, the cable connected to the power supply voltage transformer cable breaks need to be done to prevent rainwater immersion treatment, the installation of the upper U-type fixed (when using PT to take power). The controller side of the cable should be fixed under the U-type, to prevent rainwater down the cable into the plug (when using PT to take power).
