Five-prevention interlocking design

Avoid opening and closing the isolating switch with load - the isolating operation hole is blocked by the interlocking plate after the circuit breaker is closed
Avoid mis-opening and mis-closing of circuit breaker and high-voltage load switch—after the lower cabinet door is opened, the circuit breaker can not be opened
Prevent live closing of earthing switch—the isolating and earthing operation hole is blocked by interlocking plate after closing of circuit breaker
Prevent power transmission with grounding switch – the interlocking plate after the circuit breaker is closed blocks the grounding operation hole
Prevention of straying into the charged compartment - the door of the cable room can only be opened after the grounding switch is closed first and then the circuit breaker is closed again
