● Design feature
▶ The vacuum interrupter circuit breaker and load switch module are encapsulated by epoxy resin. Modular integrated main circuit with manual and electric three-station disconnector.
▶ The vacuum interrupter circuit breaker module has the ability to open and close short-circuit current.
▶ There is a visible fracture in the closing grounding position of the three-station disconnector, and the disconnector and the grounding switch can quickly open and close the short-circuit current.
▶ The epoxy resin insulated air chamber box sealed by three-station isolating switch can pressurize dry air by 0.04Mpa. It is equipped with a pressure gauge to monitor the internal pressure online to prevent leakage and extravasation, and to protect the isolating switch and grounding switch.
