Problems solved by technology

[0003] 1) As mentioned above, both the lower plate 10 and the upper plate 11 of this indoor rectangular busbar fixing fitting are made of aluminum. Due to the low mechanical strength and poor flexibility of this material, it is often used during the actual installation operation. There will be a situation where the lower plate 10 and the upper plate 11 are broken;
[0004] 2) This kind of indoor rectangular busbar fixing fittings is generally processed by cast aluminum hot-dip galvanizing process. Because the process is relatively backward, and the manufacturer is in the need of cost control, the process is not strictly controlled, so it is inevitable that the surface of the fixing fittings There are a large number of defects such as sharp corners and burrs, and these defects will bring great hidden dangers to the safe operation of the equipment in the high-voltage electric field;
[0006] 4) When the high-voltage equipment is actually used, it is necessary to increase or decrease the number of layers of the indoor rectangular busbar 7 due to changes in load or carrying capacity. In this case, it is necessary to replace the indoor rectangular busbar fixing fittings of different specifications. It will lead to an increase in material costs, increase the labor intensity of maintenance personnel, and increase the power outage time, thereby reducing electricity sales and affecting the benefits of the power company.

Abstract

The invention discloses a variable-height energy-storage support fitting for an indoor rectangular bus. The variable-height energy-storage support fitting comprises a base, a screw, a spring, a stop copper plate, a bolt and two fixing rods. The base is composed of a long vertical plate, a short vertical plate and a horizontal plate. The middle of the bottom of the horizontal plate is provided with the bolt. The lower portion of the spring winds the outer circumference of the short vertical plate, and the upper portion of the spring extends outward in the linear form. The lower portions of the fixing rods are vertically inserted in the front and the rear ends of the short vertical plate, respectively. The stop copper plate is horizontally arranged upon the short vertical plate. Two ends of the stop copper plate are provided with holes allowing the fixing rods to penetrate. The bolt vertically penetrates the stop copper plate and the middle of the short vertical plate so as to fix the stop copper plate. The variable-height energy-storage support fitting has the advantages that the components are made of the materials equal to that of the indoor rectangular bus; compare with the aluminum, the copper material is better in ductility and flexibility and never breaks; fastening height is adjustable, so that the fitting is not required to change while increasing or decreasing layers of the indoor rectangular bus.

Description

technical field [0001] The invention belongs to the technical field of devices for power systems, and in particular relates to a variable-height energy storage type indoor rectangular busbar fixing hardware. Background technique [0002] At present, in the power system, discharge accidents such as flashover, short circuit, and breakdown often occur in high-voltage equipment, and the frequency of the above-mentioned accidents in the busbar barrel or busbar room is relatively high. The content of suspended components is quite different from the previous ones (such as salt spray and other suspended substances with more complex components), and it is also related to factors such as the small insulation distance. Therefore, the current indoor rectangular busbars are often fixed with fixing fittings. figure 1 It is a side view of a currently commonly used indoor rectangular busbar fixing hardware structure. like figure 1 As shown, this indoor rectangular bus bar fixing fitting i...
