Description

Technical Field

[0001] The utility model relates to the technical field of high-voltage isolating switches, in particular to an anti-loosening high-voltage isolating switch. Background Art

[0002] High-voltage disconnectors are important switchgear in the electrical systems of power plants and substations, and must be used in conjunction with high-voltage circuit breakers. Disconnectors are suitable for indoor installations with three-phase AC 50Hz and rated voltage 12KV. They are used to connect, disconnect or convert lines when high-voltage equipment is under voltage but under load. Its main functions are to ensure the safety of high-voltage electrical appliances and devices during maintenance work and to isolate voltage.

[0003] The high-voltage isolating switch needs to be installed on a corresponding mounting base for use, but the friction between the contact part between the high-voltage isolating switch and the mounting base is relatively small, which causes the high-voltage isolating switch to loosen easily, and this needs to be improved.

[0007] The fixing mechanism includes a fixed box, a rotating rod, a movable rod, a rotating ring, a spring, a turntable, an insertion rod, a screw, a movable plate, a guide rail, and a clamping assembly. The rotating rod is installed on the fixed box, the movable rod is installed on the inner side of the rotating rod, the rotating ring is fixed on the outer side of the rotating rod, the spring is installed on the front of the rotating ring, the turntable is installed on the front of the spring, the insertion rod is fixed on the turntable, the screw is fixed on the rear of the rotating rod, the movable plate is installed on the outer side of the screw, the guide rail is installed inside the fixed box, and the clamping assembly is fixed under the movable plate.

[0012] Preferably, the limiting ring is welded to the bent rod, and the number of the sockets is twenty-four.

[0013] Compared with the prior art, the beneficial effects of the utility model are as follows:

[0014] By setting a fixing mechanism, when using the device, the device is placed on a corresponding mounting seat, and the turntable is pulled forward. The turntable drives the movable rod and the insertion rod to move, the spring is stretched, and the turntable can be rotated when the insertion rod moves to the corresponding position.
