Outdoor rainproof and heat dissipation power distribution cabinet

Abstract

The invention discloses an outdoor rainproof and heat dissipation power distribution cabinet. The outdoor rainproof and heat dissipation power distribution cabinet comprises a base; the top of the base is connected with a cabinet body through damping supporting columns; a plurality of annular dustproof nets are uniformly arranged at the bottom of the side wall of the cabinet body; the annular dustproof nets are used for preventing dust from entering the cabinet body from an air inlet; the position, positioned in the air inlet, of the bottom of the inner side wall of the cabinet body is connected with the annular dustproof nets which are matched with the inner side wall of the cabinet body; a protection net connected with the inner side wall of the cabinet body is also arranged at the internal bottom of the cabinet body; the protection net is positioned above the annular dustproof nets; a motor is also fixedly arranged at the internal bottom of the cabinet body through a bracket; a fanblade is fixedly mounted on a motor shaft at the top end of the motor; a top cover is fixedly connected with the top of the cabinet body; the top cover adopts an inverted V shape; and a plurality of heat dissipation holes are uniformly formed in the top cover. By virtue of the damping supporting columns, the cabinet body is connected with the base, thereby protecting electronic elements in the power distribution cabinet; and by virtue of rotation of a fan, active air sending and heat dissipation can be performed, and a high heat dissipation effect is achieved.

Description

technical field [0001] The invention relates to the technical field of power equipment, in particular to an outdoor rainproof and heat dissipation power distribution cabinet. Background technique [0002] The power distribution cabinet can also be called a distribution box. In a popular sense, a power distribution cabinet is a cabinet that integrates electrical components for power distribution. The power distribution cabinet mainly has two functions: one is to distribute and control the electrical equipment, and the other is to provide power-off protection when the circuit is overloaded, short-circuited and leaked. When the line fails, it is beneficial to control the fault range and also It is convenient to quickly find out the fault point and eliminate it in time without large-scale power outage. In addition, it is convenient to place various protective devices in the power distribution cabinet, such as fuses (fuses) to prevent short circuit, air switches to prevent overl...
