Abstract

The utility model discloses armored moving alternating-current metal switch equipment which comprises a cabinet body and a central withdrawable component. The cabinet body is divided into a breaker chamber, a bus bar chamber, a cable chamber and a relay chamber through metal baffles; the central withdrawable component is installed in the breaker chamber through a guide rail and a propelling mechanism; heaters are respectively installed in the breaker chamber and the cable chamber; a grounding copper bar is arranged at the bottom of the cable chamber; and pressure release channels are arranged on the side walls of the cable chamber and the bus bar chamber. The armored moving alternating-current metal switch equipment can prevent condensation and high voltage from being produced inside the equipment, so as to avoid risks; and as the grounding state is good, the safety of operating personnel is guaranteed when the operating personnel contacts the cabinet body.

Description

A kind of armored withdraw type AC metal switchgear

Technical field

The utility model relates to a kind of electric control appliance structure, is specifically related to a kind of armored withdraw type AC metal switchgear structure.

Background technology

Armored withdraw type AC metal switchgear is applicable to that 3～10KV exchanges the usefulness that electric energy was accepted and distributed in conduct in the electric power system of three-phase 50Hz single busbar connection, can be widely used in all types of power plants, in transformer station and the industrial and mining enterprises.

Armored withdraw type AC metal switchgear of the prior art is owing to adopt closed structure, cabinet inside in the bigger climatic environment of high humility or variations in temperature is easy to generate condensation and causes danger, cabinet inside also is easy to generate high-pressure phenomena, in addition, because traditional armored withdraw type AC metal switchgear is not provided with special ground connection copper bar, ground state is bad, causes security performance poor.

The utility model content

The purpose of this utility model is to provide a kind of armored withdraw type AC metal switchgear, solve in the above-mentioned background technology that traditional armored withdraw type AC metal switchgear inside is easy to generate condensation and high-pressure phenomena causes danger, and the bad relatively poor problem of security performance that causes of ground state.

For achieving the above object, the utility model by the following technical solutions.

A kind of armored withdraw type AC metal switchgear, comprise that cabinet and middle can extract parts out, described cabinet utilizes metal partion (metp) to be divided into breaker chamber, bus-bar room, the cable vault, relay bungalow, described middle can be extracted parts out and utilize guide rail and propulsive mechanism to be installed in the breaker chamber, this middle structure has been saved the space of breaker chamber, and more help the installation of cable, be with the remarkable distinguishing characteristics of traditional product, in order to prevent in the bigger climatic environment of high humility or variations in temperature, to produce the danger that condensation brings, the utility model is installed heater respectively in breaker chamber and cable vault, so that can prevent when in above-mentioned environment, using that corrosion from taking place, in the bottom, cable vault the ground connection copper bar that links to each other with each earth element is set, this ground connection copper bar can run through adjacent each cabinet, and well contact with cabinet, the sidewall of described cable vault and bus-bar room is provided with pressure release passage, room pressure can be discharged.

As a kind of improvement, described ground connection copper bar size is 10 * 40mm.

As a kind of improvement, the top of described cabinet also is provided with little bus-bar room, conveniently switchgear is coupled together.

The utility model has following beneficial effect owing to adopted above structure:

1. in breaker chamber and cable vault, be provided with special heater, even make that inside was not easy to produce the condensation phenomenon when switchgear was worked in the bigger climatic environment of high humility or variations in temperature;

2. the sidewall at cable vault and bus-bar room is provided with pressure release passage, room pressure can be discharged, and prevents because the device interior hypertonia produces dangerous;

3. in the bottom, cable vault special ground connection copper bar is set, ground state is good, guarantees the safety when operating personnel touch cabinet.
