Description

Technical Field

[0001] This utility model relates to the field of disconnecting switch technology, specifically a disconnecting switch that is easy to disassemble. Background Technology

[0002] Disconnect switches generally refer to high-voltage disconnect switches, that is, disconnect switches with a rated voltage of 1kV and above. They are often simply called disconnect switches. Outdoor disconnect switches are the most widely used high-voltage electrical appliances on power lines. They are mainly used to isolate the power supply of distribution lines during maintenance to improve operational safety. They have a clear isolation break and are mostly installed on overhead lines and substations. There are two main types of outdoor disconnect switches: one is phase-by-phase operation, where an insulating rod is used to pull open the disconnecting blade to isolate the power supply; the other is three-phase linkage operation, where an insulating rod is used to pull the manual mechanism, which opens the disconnect switch through the transmission components to isolate the power supply.

[0003] Currently, most existing outdoor disconnect switches are fixed using a combination of threads and bolts. This makes disassembly of the device very troublesome when maintaining the outdoor disconnect switch. Moreover, the staff must turn off the disconnect switch before each maintenance, but the disconnect switches are usually located at a high position, which greatly increases the difficulty of maintenance and also increases the danger during later maintenance.
