Indoor alternating-current metal armored removable switch equipment cabinet

Abstract

The invention is suitable for the technical field of switch cabinets, and provides an indoor alternating current metal armored movable switch equipment cabinet which comprises a cabinet body, a first partition plate and a second partition plate which are oppositely arranged in the cabinet body. The first partition plate and the second partition plate divide the cabinet body into an air inlet bin, an air outlet bin and a containing cavity capable of containing electric appliance elements, when the air inlet pipe, the air outlet pipe, the heat dissipation pipeline and the suction device work, air in the cabinet body is sucked into the air outlet bin, heat is discharged along the air outlet pipe communicated with the air outlet bin, and therefore the heat dissipation effect of the electric appliance elements is improved. And simultaneously. Cold air in outside air enters the air inlet bin along the air inlet pipe, enters the corresponding first air guide pipe along the air inducing hole formed in the first partition plate, reaches the corresponding second air guide pipe along the first air guide hole formed in the first air guide pipe and enters the containing cavity along the second air guide pipe, and therefore heat exchange is completed. And rapid heat dissipation processing is realized.

Description

technical field [0001] The invention belongs to the technical field of switch cabinets, in particular to an indoor AC metal armored removable switch equipment cabinet. Background technique [0002] At present, the metal armored central removable switchgear is also referred to as the central cabinet. It is a high-voltage power distribution device with a maximum working voltage of 3.6 / 7.2 / 12kV. It is an indoor complete power distribution device for a three-phase AC 50Hz single-bus section system or a double-bus section system. It is used to receive and supply and distribute 3.6-12kV network power, and to control, protect, monitor and measure the power circuit. The central switchgear is mainly used in power plants, power transmission of small and medium-sized generators, and secondary substations in power systems. Power receiving and transmission, power distribution of industrial and mining enterprises, and starting of large high-voltage motors. [0003] The existing central ...

AI Technical Summary

Problems solved by technology

[0004] The above-mentioned existing technical solutions have the following defects: the electrical components in the central cabinet will generate a large amount of heat energy during the working process, and the circulating air flow cannot effectively dissipate the internal heat, resulting in internal heat accumulation and affecting the use of electrical equipment
