Ring main unit for outdoor use

Abstract

The invention discloses a ring main unit for outdoor use. The ring main unit includes a cabinet body. A radiating port is arranged in the center of the top part of the cabinet body. A fan is fixedly connected to the center of the top part of the inner cavity of the radiating port in a crosswise manner. Springs are welded on two sides of the top part of the cabinet body vertically. A protection cover is welded to the top part of the springs. Air vents are arranged on two sides in the bottom part of the cabinet body. Waterproof covers are welded to the bottom parts of the outer walls on two sides of the cabinet body. According to the invention, through arrangement of the cabinet body, the radiating port and the fan, air flow in the cabinet body can be accelerated effectively, and heat dissipation efficiency of electric devices in the cabinet body can be improved. Through the arrangement of the springs and the protection cover, snows accumulated on the top part of the protection shade canbe shaken off through shaking the protection cover in heavy snow weather, so that influence on the ring main unit by snow can be reduced effectively. Through the arrangement of the waterproof coversand a sponge filtering board, water is made to flow along the outer walls of the waterproof covers, so that the rainproof effect of the ring main unit is improved effectively.

Description

technical field [0001] The invention relates to the technical field of ring network cabinets, in particular to a ring network cabinet for outdoor use. Background technique [0002] The ring network cabinet is a group of high-voltage switchgear installed in the steel plate metal cabinet or made into an assembled spaced ring network power supply unit. Its core part uses load switches and fuses. It has simple structure, small size, low price, and can be Improve power supply parameters and performance and power supply security and other advantages. [0003] Because some ring network cabinets need to be installed outdoors, in order to increase heat dissipation, traditional ring network cabinets often adopt the natural heat dissipation method of setting louvers on the side walls or door panels, while traditional louvers have no additional protection measures, poor waterproof performance, and lower When it rains, rainwater easily enters the cabinet and causes electrical malfunctio...

AI Technical Summary

Problems solved by technology

[0004] The purpose of the present invention is to provide a ring network cabinet for outdoor use, which has the advantages of good heat dissipation effect and rain and snow protection, and solves the problem that the traditional ring network cabinet has poor protection effect on the electrical appliances inside the cabinet when it is used outdoors
