Problems solved by technology

[0002] At present, the high-voltage components of the EMU (such as figure 1 The shown vacuum circuit breaker 6, high-voltage isolating switch 10, high-voltage grounding switch 5, etc.) are usually scattered and installed on the roof of the vehicle, and the installation space can be freely matched, which is easy to implement, but because the high-voltage components are exposed outside, the external environment has great influence on its use. It is often affected by environmental factors such as wind, dust, rain, snow, smog, etc., causing pollution flashover of the high-voltage components on the roof, and even some serious problems such as explosions. At the same time, the above-mentioned high-voltage components are accelerated. The deterioration and failure of the EMU is not conducive to the improvement of the wind resistance performance of the EMU

Abstract

The invention discloses a high-voltage equipment box of a D-series high-speed train and the high-speed train provided with the high-voltage equipment box. The high-voltage equipment box comprises a box body and a incoming cable terminal, a lighting arrester, a to-transformer cable terminal, a high-voltage isolation switch, a to-other-compartment cable terminal, a vacuum circuit breaker and a high-voltage ground switch which are arranged in the box body, wherein the box body comprises a first side wall, a second side wall, a third side wall and a fourth side wall, the first side wall and the second side wall are opposite to each other, and the third side wall and the fourth side wall are opposite to each other. In the high-voltage equipment box disclosed by the scheme, a high-voltage part is arranged in the sealed box body, the influence of an external environment on product application is eliminated, the insulation capability is greatly improved, the serious problems that pollution flashover occurs in the high-voltage part on a roof caused by environmental factors such as wind, dust, rain, snow and haze when the high-voltage equipment box is originally arranged externally and even some parts are exploded are prevented, and a quality accident caused by environmental influence can be further effectively prevented.

Description

technical field [0001] The invention belongs to the field of rail vehicles, and in particular relates to a high-voltage equipment box for an EMU and an EMU equipped with the high-voltage equipment box. Background technique [0002] At present, the high-voltage components of the EMU (such as figure 1 The shown vacuum circuit breaker 6, high-voltage isolating switch 10, high-voltage grounding switch 5, etc.) are usually scattered and installed on the roof of the vehicle, and the installation space can be freely matched, which is easy to implement, but because the high-voltage components are exposed outside, the external environment has great influence on its use. It is often affected by environmental factors such as wind, dust, rain, snow, smog, etc., causing pollution flashover of the high-voltage components on the roof, and even some serious problems such as explosions. At the same time, the above-mentioned high-voltage components are accelerated. The deterioration and fail...
