Power electrical switch cabinet with good waterproof function

Abstract

The invention relates to the technical field of power electrical equipment, and discloses a power electrical switch cabinet with a good waterproof function, which comprises a cabinet body and a cabinet door; a waterproof rubber pad is arranged between the cabinet body and the cabinet door, and a support rod is fixedly arranged at the top of the cabinet body. The invention discloses the power electrical switch cabinet with the good waterproof function; a servo motor, a PVC waterproof cloth, an iron sheet, an iron core and an electromagnet formed by electrifying a coil are arranged; during raining, a rain and snow sensor senses rain and sends information to a controller; the controller issues a command to a pulse encoder to send out a pulse to enable the servo motor to rotate forwards, so the PVC waterproof cloth wound on a winding drum is put down, and the controller controls an electromagnetic switch to switch on a circuit of the coil, so that the coil is powered on to form the electromagnet with the iron core; the electromagnet attracts the iron sheet, so the PVC waterproof cloth seals a heat dissipation groove; it is prevented that in rainy days, wind that carries rainwater enter the cabinet body, and components in the cabinet body are affected with damp or short-circuited.

Description

technical field [0001] The invention relates to the technical field of electric power equipment, in particular to a power electric switchgear with better waterproof function. Background technique [0002] The power electrical switchgear plays a very important role in the power system. Modern power systems have higher and higher requirements for power quality, and correspondingly put forward higher requirements for the reliability of the switchgear. The switchgear is a complex The system has complicated components inside. The switchgear is mainly composed of circuit breakers, isolating switches, load switches, operating mechanisms, transformers and various protection devices, and some electric switchgears are installed outdoors. [0003] 1. Considering the heat dissipation of the internal components of the electric power switchgear, the existing technology generally has cooling holes or cooling grooves on the cabinet body, and this cooling hole or cooling groove is generally ...
