Description

Technical Field

[0001] The utility model relates to the technical field of high and low voltage switch cabinets, in particular to a dustproof high and low voltage switch cabinet. Background Art

[0002] As an important part of the power system, high and low voltage switchgear undertakes the key task of connecting high or low voltage cables and is widely used in various outdoor environments. In order to ensure its normal operation and extend its service life, the maintenance of high and low voltage switchgear is particularly important. Most existing switchgears have obvious deficiencies in dust and rain protection, which directly affects the operating safety and service life of the switchgear. The maintenance of high and low voltage switchgear usually requires opening the cabinet door, which puts forward higher requirements for dust and rain protection. If the dust and rain protection performance of the switchgear is not good, then the dust, rain and other impurities from the outside will invade the inside of the cabinet, causing damage to the internal electrical components and even causing failures. In addition, if the switchgear is exposed to the external environment for a long time, if there is no effective dust and rain protection measures, its shell and internal electrical components are also prone to corrosion and damage, thereby shortening its service life. Many switchgears are simply equipped with ventilation holes. Although they meet the heat dissipation requirements to a certain extent, they are incapable of rain protection performance. Once encountering severe rain and snow weather, rainwater can easily invade the inside of the cabinet through the ventilation holes, causing damage to the electrical components. At the same time, due to the unreasonable design of the ventilation holes, the heat dissipation effect of the switch cabinet is often unsatisfactory, resulting in excessively high temperatures inside the cabinet, further aggravating the aging and damage of electrical components.

[0003] After searching, the existing patent (publication number: CN219611033U) discloses a "high and low voltage switch cabinet assembly for mining, including a cabinet body, a cabinet door is installed on the upper end of the cabinet body, a control display device is installed on the cabinet door, and a fixed frame is detachably connected to the cabinet door through a connecting assembly, an observation window is provided on the fixed frame, and a transparent glass is installed on the observation window: a dust cleaning assembly is installed on the cabinet door and is used to clean the dust on the outer surface of the transparent glass. By setting the fixed frame, the transparent glass can be installed on the cabinet door, so that the display screen and button components of the control display device are dust-proofed by the fixed frame and the transparent glass, so as to prevent the dust in the mine from entering the control display device and affecting the normal use of the control display device. In addition, by setting the dust cleaning assembly, the dust adhered to the outer surface of the transparent glass can be cleaned, so that there is no need to manually wipe the transparent glass manually, thereby making the operation convenient."

[0004] Although this patented technology reduces the number of cabinet opening operations by providing transparent glass as an observation window and a dust cleaning component for the observation window, it lacks heat dissipation and has no dust prevention and reduction measures to avoid cabinet opening operations, resulting in limited heat dissipation and dust prevention capabilities. Therefore, technical personnel in this field provide a dustproof high and low voltage switch cabinet to solve the problems raised in the above background technology. Utility Model Content

[0005] The purpose of the utility model is to solve the shortcomings of the prior art, which include simply setting an observation window and an observation window dust cleaning component, lacking active heat dissipation capability, and lacking dust prevention and reduction measures when the cabinet is opened.
