Description

Technical Field

[0001] The utility model relates to the technical field of power equipment installation, in particular to a power capacitor clamping tool. Background Art

[0002] Power capacitors are mainly used to improve the power factor of the power system, reduce reactive power, thereby reducing line losses and improving the operating efficiency of the power grid. When installing power capacitors in the power system, they need to be fixed on a specific bracket to ensure the stability and safety of the capacitor.

[0003] After searching, Chinese patent announcement number: CN212192837U discloses a power capacitor clamping tool, including a base plate, a splint, a gasket and an adsorption rod, the top of the base plate is respectively provided with a fixed body and a movable body, the fixed body is connected to the top of the base plate by welding, the movable body is connected to the top of the base plate by a slide rail, and the inner sides of the movable body and the fixed body are provided with a mounting seat and a splint. This power capacitor clamping tool, by adding a splint on the inner side of the mounting seat and combining it with the gasket on the base plate, better solves the problem that the clamping tool is prone to different degrees of wear when clamping the power capacitor. Since the splint is made of rubber material, its outer surface is relatively soft. In this way, when it is clamped in contact with the power capacitor, no matter how strong the clamping force is, it will not cause wear on the outer surface of the power capacitor, which greatly improves the convenience during use. The overall structure is simple and the functionality is strong, which can well protect the power capacitor from wear.

[0004] During use of the above-mentioned equipment, by adding a clamping plate on the inner side of the mounting base and combining it with the gasket on the bottom plate, the problem of varying degrees of wear and tear on the clamping tool when clamping the power capacitor is better solved. However, power capacitors usually have different models. During actual fixation, the clamping device of the equipment cannot be adjusted in height, resulting in the inability to achieve the expected effect of fixing power capacitors of different heights. Therefore, a power capacitor clamping tool is proposed to solve the above problem. Utility Model Content
