Interlock Devices - High Voltage switchgear
- Only when the circuit-breaker is in the open switch state, the handcart can shift from the test/isolation position to the working position and vice versa.
- Only when the circuit-breaker handcart is at the test/isolation position, the ground switch can be closed.
- When the ground switch is closed, the handcart cannot shift from the test/isolation position to the working position.
- When the handcart is at the working position, the secondary plug is locked and cannot be pulled out. Only when the handcart is at the test position and the secondary plug has been pulled out, the handcar can be moved out of the Switchgear.
- Only when the ground switch is closed, the backdoor of the Switchgear can be opened.
- Only if the circuit-breaker handcart is at the test/working position, the circuit-breaker can be closed.
