A Plateau Vacuum Circuit Breaker Embedded Pole

Abstract

The invention relates an embedded pole of a plateau vacuum circuit breaker. The embedded pole comprises an embedded pole body (1) and a base (3) connected with the embedded pole body (1). An insulating pull rod (4) is arranged in the middle of the embedded pole body (1). The embedded pole is characterized by further comprising an insulating sealing element (2). One end of the insulating sealing element (2) is connected with the insulating pull rod (4), the other end of the insulating sealing element (2) is connected with the embedded pole body (1) and the base (3), and then an embedded pole inner cavity can be sealed. The embedded pole has the advantages that the insulating sealing element has a tower-shaped layered cross section and is pressed between the embedded pole body of the plateau vacuum circuit breaker and the base of the plateau vacuum circuit breaker, so that the creepage distance is increased, the insulating performance is improved, and the destructive discharge phenomena of creepage, flashover and the like are effectively avoided.

Description

technical field [0001] The invention relates to a solid-sealed pole of a plateau type vacuum circuit breaker. Background technique [0002] The plateau type vacuum circuit breaker is a switching device that turns on and off the no-load and load current in the high-voltage circuit, and can quickly cut off the fault current. As the core component of the plateau type vacuum circuit breaker, the solid-sealed pole has poor reliability and low safety factor in the harsh environment, especially in the environment with wind, sand, humidity, pollution and high altitude, the inner surface of the solid-sealed pole and the surface of the insulating rod It is easy to cause flashover, creepage and other phenomena to cause destructive discharge and damage the solid-sealed pole. [0003] Therefore, there is an urgent need for a plateau vacuum circuit breaker solid-sealed pole that is resistant to moisture, condensation, and pollution in the above-mentioned environment, so as to realize the...
