Problems solved by technology
[0002] Due to sunlight and self-heating of the outdoor power distribution cabinet, the temperature inside the cabinet is likely to rise, and what is more, it will cause the electrical components inside the power distribution cabinet to burn out. In order to prevent this from happening, the existing power distribution cabinet The cabinet generally punches louvers on the side wall of the power distribution cabinet, then adds a cover, and adds a filter to the louvers
This kind of power distribution cabinet is only ventilated through the shutters, and the power distribution cabinet can only dissipate heat locally. , its dust-proof effect is not good, and it is easy to affect the normal operation of the equipment; if the power distribution cabinet installed on the roadside or in the green belt uses this structure, when the sprinkler passes by or it rains, water can easily enter the distribution cabinet from the shutters. In the electric cabinet, the electrical components in the power distribution cabinet are burned, causing unnecessary losses

The invention discloses a power distribution cabinet with good dustproof ventilation performance. The power distribution cabinet comprises a power distribution cabinet body, wherein the power distribution cabinet body comprises a head cover and side plates; the power distribution cabinet is characterized in that an air outlet is formed in the surface of the head cover; the upper surface of the head cover is connected with an air outlet device through a bolt; the air outlet is located in the air outlet device; a plurality of air intake ducts are formed in the side plates; arc-shaped baffle plates are arranged at the outer sides of the air intake ducts; the inner side of each side plate is connected with an air inlet device through the bolt; and each air inlet device corresponds to the positions of the air intake ducts. According to the power distribution cabinet with good dustproof ventilation performance, through arrangement of the air inlet devices and the air outlet device at different positions, a convection current can be formed in the power distribution cabinet body, so that the ventilation and heat dissipation effects are relatively good. The inside of the power distribution cabinet body can be isolated from external air by a cavity formed by a partition plate; filter holes in filter pipes can filter relatively large dust particles; and then dust particles are filtered through filter nets, so that the filtering effect is relatively good.
Description
technical field [0001] The invention relates to the technical field of electric equipment, in particular to a power distribution cabinet with good dustproof and ventilation performance. Background technique [0002] Due to reasons such as light and self-heating, the outdoor power distribution cabinet can easily increase the temperature in the box, and even cause the electrical components inside the power distribution cabinet to burn out. In order to prevent this from happening, the existing power distribution The cabinet is generally punched with shutters on the side wall of the power distribution cabinet, then a cover is added, and a filter screen is added to the shutters. This kind of power distribution cabinet is only ventilated through the shutters, and the power distribution cabinet can only be partially dissipated, and the heat dissipation effect is not good, and the electrical components inside the power distribution cabinet will still be burned due to excessive tempe...
