Description

High voltage vacuum circuit breaker bracket device with rhombic fins

technical field

The utility model belongs to the technical field of high-voltage electrical appliances and relates to a high-voltage vacuum circuit breaker, in particular to a support device for a high-voltage vacuum circuit breaker with rhombic wings.

Background technique

Reciprocating high-voltage vacuum circuit breaker switches are widely used in high-voltage and various fields of national economy. Among the parts of high-voltage vacuum circuit breakers, the opening and closing cams are conductive components and also key parts in high-voltage vacuum circuit breaker switches. The traditional support The frame is installed on the vacuum interrupter to conduct electricity, but because of its small surface area, the heat dissipation is not good, and the temperature rises and overheats easily after long-term use, which will cause the insulating parts to burn, which is unsafe and causes great waste; and the conductivity is not good. High, but also cause power loss, uneconomical.

Utility model content

In order to overcome the problems of heating, low conductivity, and power loss in the upper bracket, the utility model adopts the idea of installing the upper bracket. The specific technical scheme is as follows:

A high-voltage vacuum circuit breaker support device with rhombic fins, including a vacuum interrupter (1) and an upper support (2), characterized in that the upper support (2) is installed on the vacuum interrupter (1), And connected by screws (3), the upper bracket (2) can cooperate with the closing action of the vacuum interrupter (1), and the upper bracket (2) has a plurality of rhombic fins (4) for heat dissipation.

Further, the rhomboid fins (4) are distributed symmetrically, with 9 pieces on one side.

Further, the material of the upper bracket (2) is copper, and the material of the screw (3) is steel.

Further, the upper bracket (2) is T2 red copper, and the steel material of the screw (3) is Q235.

Compared with the prior art, the useful technical effect of the utility model is that the utility model can realize a higher ampacity of the high-voltage vacuum circuit breaker, significantly improve the conductivity, and reduce the contact resistance; multiple rhombic fins can increase the heat dissipation area and reduce the The vacuum interrupter room rises and generates heat, which reduces the heat accumulation of the entire circuit breaker circuit.
