Power distribution cabinet with lightning arrester

Abstract

The invention discloses a power distribution cabinet with a lightning arrester. The power distribution cabinet comprises a power distribution cabinet body, a lightning protection and rain shielding assembly, a heat dissipation adjusting assembly, hinges, a cabinet door, an observation window, a cooling fan, an observation window dust wiping assembly, a handle and a bearing. The lightning protection and rain shielding assembly is arranged on the outer wall of the top end of the power distribution cabinet body. Supporting frames are welded and fixed to the outer walls of the two sides of the topend of the power distribution cabinet body. Rain shielding covers are welded and fixed to the outer walls of the top ends of the supporting frames. According to the invention, through the arrangementof the lightning protection and rain shielding assembly, the lightning protection of the power distribution cabinet is realized. The damage caused by lightning stroke is reduced. The whole power distribution cabinet is sheltered from rain through the conical rain sheltering cover, so that the corrosion of rainwater to the power distribution cabinet is reduced. Through the arrangement of the heatdissipation adjusting assembly, the exhaust air rate can be adjusted. Therefore, the control over the heat dissipation amount is achieved. Through the arrangement of the observation window dust wipingassembly, the dust contaminated on the observation window can be automatically wiped and removed. The later observation by workers through the observation window is facilitated.

Description

technical field [0001] The invention relates to the technical field of power distribution cabinets, in particular to a power distribution cabinet with a lightning protection device. Background technique [0002] Power distribution cabinets are boxes in which voltage appliances are placed; collectively referred to as power distribution centers, they are centrally installed in substations of enterprises to distribute power to lower-level power distribution equipment in different locations. In the field of power distribution cabinets, due to the power distribution cabinets A large number of connectors and various electronic components are installed inside; it is widely used in the power equipment in the existing market, but the structure of the existing power distribution cabinet is relatively uniform, and the existing power distribution cabinet is often installed outdoors In use, thunderstorms are often encountered.

[0002] Power distribution cabinets are boxes in which voltage appliances are placed; collectively referred to as power distribution centers, they are centrally installed in substations of enterprises to distribute power to lower-level power distribution equipment in different locations. In the field of power distribution cabinets, due to the power distribution cabinets A large number of connectors and various electronic components are installed inside; it is widely used in the power equipment in the existing market, but the structure of the existing power distribution cabinet is relatively uniform, and the existing power distribution cabinet is often installed outdoors In use, thunderstorms are often encountered. The existing power distribution cabinets are not equipped with lightning protection and rain protection components, which are easily affected by lightning strikes and rain erosion. The inside of the power distribution cabinet often uses cooling fans to cooperate with ventilation holes to dissipate heat, but it cannot be exhausted. The adjustment of the quantity is not conducive to the later control of heat dissipation; the door of the power distribution cabinet is often inlaid with an observation window, and the power distribution cabinet is placed outside for a long time. The observation window is easily contaminated with dust and affects the later observation.
