Electrical "five defenses"

Update date:2018-05-04 Source:MAXGE

In order to ensure personal and equipment safety, five kinds of anti-misuse functions should be provided for electrical equipment.

Electrical "five defenses"

1, to prevent load points, combined isolation switch. (Circuit breakers, load switches, and contactor closing states cannot operate isolation switches.)

2, to prevent misclassification, misuse of circuit breakers, load switches, contactors. (Only operating instructions and operating equipment can operate on operated equipment)

Electrical "five defenses"

3. Close the circuit breaker and load switch when the grounding switch is in the closed position. (Only when the grounding switch is in the open state, can the isolating switch or handcart be moved to the working position to operate the circuit breaker and the load switch is closed)

4, to prevent accidental grounding switch when charged. (Only after the circuit-breaker is in the open state, can the isolation switch or handcart be operated to retreat from the working position to the test position in order to close the earthing switch)

Electrical "five defenses"

5, to prevent mistakes into the charged compartment. (Open the door into the compartment only when the compartment is not powered)
