Description

Technical Field

[0001] The utility model relates to the technical field of electric power equipment, in particular to a fixing device for a high-voltage isolating switch. Background Art

[0002] A high-voltage isolating switch is a switching device that is mainly used for "isolating power supply, switching operations, connecting and disconnecting low-current circuits" and has no arc extinguishing function. Its main function is to ensure the safety of high-voltage electrical appliances and devices during maintenance work, and to isolate voltage. It cannot be used to cut off, input load current, and interrupt short-circuit current. It can only be used for certain switching operations that do not generate strong arcs. That is to say, it does not have an arc extinguishing function. During the use of the high-voltage isolating switch, a fixing device needs to be used to fix the high-voltage isolating switch.

[0003] As disclosed in a Chinese patent: A high-voltage disconnector fixing bracket, application number: CN202321503560.X, comprising a base, the upper surface of the base is fixed with opposing vertical columns, a slidable support rod is provided in the vertical column in the longitudinal direction, the top of the support rod is fixedly connected with a mounting seat, the surface of the mounting seat is rotatably connected with a switch, and an adjustment component is provided between the support rod and the base for adjusting the position of the support rod and fixing it. The high-voltage disconnector fixing bracket of the utility model, through the rotation of the synchronization rod, cooperates with the first bevel gear and the second bevel gear and the nut, so that the two support rods move in the longitudinal direction at the same time, which is convenient for operation and reduces the workload, and the support rod can be adjusted to any position within the length range of the slide slot to adapt to more situations.

[0004] However, in the above technical solution, in actual application, the high-voltage disconnector needs to be installed in various environments. In the above technical solution, the height of the support rod is adjusted by adjusting components and guided by the slide groove. This results in that once the high-voltage disconnector is installed in an environment with a lot of wind and sand, the wind and sand can easily enter and accumulate in the slide groove, affecting the performance of the slide groove, thereby affecting the adjustment effect of the support rod. In addition, high-voltage disconnectors are generally used in groups of several. In order to facilitate control, it is usually necessary to use a rotating column to connect the knife switches in a unified manner. At present, the rotating column and the knife switches are mostly connected by welding or bolts, and the connection method is relatively cumbersome. Utility Model Content
