High Voltage Isolating Switch Function
Date: | Read: 34
It is used to break load current and close short-circuit current, and is used to break load current, closed-loop current, no-load transformer and cable charging current, and close short-circuit current. The load switch equipped with High Voltage Disconnect Switc can withstand short-circuit current. The load switch-fuse combination with a tripping device and a high-breaking capacity fuse has a phase-off tripping function, which can cut off the short-circuit current and protect the equipment.
