Externally-hung type electrical cabinet

Abstract

The invention discloses an externally-hung type electrical cabinet. The cabinet comprises a cabinet body, a cabinet door, an efficient dust removal device, a lifting device, a sliding device and a heat dissipation device. The efficient dust removal device is arranged at the top of the cabinet body; a user starts an exhaust fan to work through a controller, the exhaust fan generates centrifugal suction force to extract dust in the box body through an air inlet window at the bottom of the box body, then, the dust is placed into a filter screen set through an exhaust port on the right side of theexhaust fan, the filter screen set is internally equipped with an activated carbon filter screen, a first-effect filter screen and a separation screen for carrying out layer-by-layer filtration on the dust, afterwards, an HEPA filter screen at the bottom of an air outlet window is used for carrying out final blocking and purification on the dust, the dust is left in the right end in the box bodyfor storage, and the user opens a top cover through a handle at the upper end of the box body so as to clean the dust in the box body. The dust collecting effect is good, the efficiency is high, and the problem that the electric cabinet works outdoors for a long time so that a large amount of dust is easy to accumulate inside the cabinet, elements are easy to damage and cleaning is inconvenient issolved.

Description

technical field [0001] The invention relates to the related field of electrical equipment, in particular to an external hanging electrical cabinet. Background technique [0002] The electrical cabinet is a cabinet made of steel to protect the normal operation of components. The materials for making electrical cabinets are generally divided into two types: hot-rolled steel plates and cold-rolled steel plates. Compared with hot-rolled steel plates, cold-rolled steel plates are softer and more suitable for the production of electrical cabinets. Electrical cabinets are widely used in the chemical industry, environmental protection industry, and power systems. , metallurgical system, industry, nuclear power industry, fire safety monitoring, transportation industry, etc. Electrical cabinets are also divided into indoor and outdoor. [0003] However, there are the following problems in the existing external hanging electrical cabinets: [0004] 1. The existing external-mounted el...

AI Technical Summary

Problems solved by technology

[0004] 1. The existing external hanging electrical cabinet, the electrical cabinet works outdoors for a long time, a large amount of dust is easy to accumulate inside, easy to damage the components, and it is inconvenient to clean

[0005] 2. The existing external hanging electrical cabinets are not easy to adjust the height of the cabinet when they are placed outside the cabinet, and affect the efficiency of later maintenance

[0006] 3. The existing external-mounted electrical cabinet, when installing or overhauling the modules in the electrical cabinet, is placed in a small internal space, which affects maintenance or installation

[0007] 4. In the existing external-mounted electrical cabinets, when the electrical cabinets are working outdoors, the internal modules generate a lot of heat. In addition to climate change, the internal temperature rises quickly and the removal is slow, which may easily cause damage to internal components or reduce their life.
