Description
Technical Field
[0001] This utility model belongs to the field of disconnecting switch technology, and specifically relates to a disconnecting switch handle. Background Technology
[0002] In the field of high-voltage electrical equipment, rotary disconnect switches are key components for circuit isolation, and the structural design of their operating mechanisms directly affects the safety and reliability of the equipment. The existing rotary disconnect switch handle fixing screws are located very close to the operating position, which poses a risk that the insulation performance may not meet the requirements, and there are safety risks when operating manually. Utility Model Content
[0003] To address the aforementioned problems, the purpose of this utility model is to provide a disconnect switch handle that is simple in structure, has high safety performance, and is easy to assemble.
[0004] This utility model is achieved through the following technical solution:
[0005] A disconnect switch handle includes an operating mechanism for operating the disconnect switch, and further includes a handle, a handle cover, and a fixing screw. The handle has a central hole. The handle cover is mounted on the upper surface of the handle. The handle is fixed to the operating mechanism via the fixing screw passing through the hole. Several grooves are provided around the upper surface of the handle. A protrusion that mates with the groove is provided at the bottom of the handle cover. An annular sealing ring is provided at the bottom of the handle cover corresponding to the hole. One end of the sealing ring contacts the bottom of the handle cover, and the other end contacts the upper surface of the handle, enclosing the fixing screw inside. A second groove is provided on the side of the handle where it connects to the handle cover. A third groove is provided on the contact surface of the upper surface of the handle where the handle cover is mounted, for limiting the position of the handle cover. Strip-shaped protrusions are provided on the left and right sides of the handle. The front end of each protrusion has a hook for engaging with the groove.
[0006] The beneficial effects of this utility model are:
[0007] This utility model has a simple structure, can be quickly assembled, has high safety performance, and is waterproof. Attached Figure Description
