Special-shaped external damage prevention device for circuit breaker platform, and installation method thereof

Abstract

The invention relates to a special-shaped external damage prevention device for a circuit breaker platform, and an installation method thereof. The device comprises an arc-shaped plate (3) which is located between two phases of a vacuum circuit breaker, one end of the arc-shaped plate (3) is connected to a vacuum circuit breaker box body platform, the other end of the arc-shaped plate (3) is connected to an isolation switch frame, and one end of the arc-shaped plate (3) is provided with a hook column connecting plate (1). The hook column connecting plate (1) is provided with a hook column (2)used for being hung into a lug hanging hole of the vacuum circuit breaker box body platform, and the other end of the arc-shaped plate (3) is provided with a magnetic attraction part used for being attracted to the isolation switch frame. Compared with the prior art, the installation method has the advantages that on the basis of not changing the existing structure of the vacuum circuit breaker, the arc-shaped plate design is adopted, and the hook column and the magnetic attraction part at the two ends of the arc-shaped plate are combined, so that the arc-shaped plate can cover the circuit breaker box body platform and the isolation switch frame, birds are prevented from nesting on the circuit breaker platform, and the effect of effectively preventing external damage is achieved.

Description

technical field [0001] The invention relates to the technical field of electric device protection, in particular to a breaker platform special-shaped anti-breakage device and an installation method thereof. Background technique [0002] Birds build nests on power lines, which can easily lead to overlapping of foreign objects on the lines, resulting in single-phase grounding or phase-to-phase short-circuit faults. With the rapid development of urban power grids, distribution line user units are relatively concentrated. In order to ensure the quality of line operation, poles Vacuum circuit breakers have been widely used in the construction of power lines. However, the position of the vacuum circuit breaker box platform and the frame with isolating knife gates, its numerous intersecting triangular structures are more likely to attract birds to build nests here. Breakage has become a major cause of vacuum circuit breaker breakout. [0003] In order to improve the defense perfor...

Problems solved by technology

[0004] The sonic bird repellent uses ultrasonic pulses that humans cannot hear to disturb the birds. According to the size of the protection area to be protected, ultrasonic bird repellents with different powers can be selected, but the construction cost of the sonic bird repellent is relatively large and cannot cover a wide range application;

[0005] The special-shaped bird repellent is to occupy the bird's foothold by adding a special-shaped bird repellent device, so as to prevent the birds from moving. The main structure of the special-shaped device has a thorn or an inverted T-shaped thorn. Most of the bird repellents are suitable for the cross-arm position of the foundation pole of the distribution line, and cannot be put into installation on the vacuum circuit breaker platform
