The Operation Sequence Of Vertical Fuse Disconnector Cannot Be Reversed

1. When operating vertical fuse switch disconnector, nhrt40 vertical fuse switch disconnector manufacturers should first check the actual disconnection position of the circuit breaker of the corresponding circuit, so as to avoid pulling and closing the isolating switch with load.
2. When the line is shut down and powered on, the isolating switch should be pulled and closed in order. When operating the power outage, the circuit breaker should be pulled first, then the line side isolating switch, and then the bus side isolating switch. The power supply operation sequence is opposite to the power outage sequence. This is because when an erroneous operation occurs, the above sequence can reduce the scope of the accident and avoid artificial expansion of the accident to the bus.
3. During the operation, if the transmission rod of the isolating switch is seriously damaged or other serious defects, it cannot be operated, and the on-duty personnel must check the opening and closing position, synchronization status, contact touch depth and other items on site phase by phase to ensure the correct operation and position of the isolating switch.
4. The isolating switch should generally be operated in the main control room. When the remote control electrical operation fails, manual or electric operation can be performed on site, but the permission of the stationmaster or technical person in charge must be obtained and it can only be carried out under on-site supervision.
