a power cabinet

Abstract

The invention discloses an electric power cabinet. An air port is formed in the upper part of the side wall of the electric power cabinet; the air port is a normally-closed vertical type louver air port; a dust removing cabinet is also arranged behind the electric power cabinet; the dust removing cabinet comprises a top cover, a bottom cover, a side plate, side ribs and filtering cloth; the filtering cloth is arranged on three surfaces, and the uncovered regions on the top cover, the bottom cover and the side plate are covered with the filtering cloth; the side plate is provided with an air outlet pipe; the air outlet pipe is provided with an air outlet fan; an outer pipe body connected with the internal space is arranged on the back plate of the electric power cabinet; the air outlet pipe is embedded in the outer pipe body; a limiting bump is arranged on one surface, which faces to the electric power cabinet, of the side plate; a limiting groove matched with the limiting bump is formed in the back surface of the electric power cabinet; and movable wheels are also arranged below the dust removing cabinet. According to the electric power cabinet, the dust removing cabinet is also arranged behind the electric power cabinet, so that the external air with relatively high dust content can be filtered by the filtering cloth of the dust removing cabinet and becomes clean; and therefore, the electric power cabinet can be applied to occasions with relatively high content of dust, and the normal operation of the internal electrical system can be ensured.

Description

technical field [0001] The invention relates to the electrical field, in particular to an electric cabinet. Background technique [0002] The power cabinet is a commonly used power infrastructure, which is equipped with a large number of power components; because the power cabinet will generate a lot of heat when it is working, the internal temperature is too high to easily affect the normal operation of electrical components. People can find out that many power cabinets are disclosed on the website of the State Intellectual Property Office, such power cabinets are as disclosed in patents 201310370187.X, 201310315992.2, 201510766091.4, etc. [0003] The existing power cabinet relies on outside air as the cooling air to cool the internal electrical components. The air inlet of the power cabinet is generally equipped with a filter screen, which is inconvenient to use in places with a lot of dust, such as the field with a lot of dust, textile workshops, In construction sites, ...

AI Technical Summary

Problems solved by technology

[0003] The existing power cabinet relies on outside air as the cooling air to cool the internal electrical components. The air inlet of the power cabinet is generally equipped with a filter screen, which is inconvenient to use in places with a lot of dust, such as the field with a lot of dust, textile workshops, In construction sites, flour mill raw material workshops, brewery raw material workshops, etc., dust is easy to block the narrow filter screen, which makes the cooling air source intercepted and affects internal cooling. If there is no filter screen, the dust directly enters the inside of the power cabinet, causing Abnormal electrical system
