High-low-voltage switch cabinet with automatic protection function

Abstract

The invention discloses a high-low-voltage switch cabinet with an automatic protection function. The high-low-voltage switch cabinet comprises a cabinet body and a machine seat, wherein connecting blocks are fixedly connected onto the bottoms of the left and right sides of the cabinet body; support rods are fixedly connected onto the inner walls of the two sides of the machine seat through fixingblocks; the connecting blocks are inserted and connected onto the support rods; a first strong power spring and a second spring power spring are connected onto each support rod in a sleeving way; thetop end of the first strong power spring is fixedly connected onto the top end of the support rod; and the bottom end of the first strong power spring is fixedly connected with the upper surface of the connecting block. Through the arrangement and the mutual matching of the cabinet body, a fan, a ventilation pipe, a multi-way pipe, an air suction head and a temperature sensor, the problem that theexisting high-low-voltage switch cabinet cannot timely and effectively discharge heat is solved; and through the arrangement and the mutual matching of a dry powder fire-fighting box, a conveying pipe, a spray head, an electric control valve and a smoke sensor, the problem that the existing high-low-voltage switch cabinet cannot perform fire hazard control on inside electric appliance elements issolved.

Description

technical field [0001] The invention relates to the technical field of high and low voltage switch cabinets, in particular to a high and low voltage switch cabinet with an automatic protection function. Background technique [0002] With the development of society and the continuous advancement of science and technology, people's living standards have been greatly improved, and the basic equipment has become more and more perfect. All aspects of modern life are inseparable from electricity. The use of electricity is convenient for people's basic necessities. In power equipment, high and low voltage switch cabinets need to be used frequently. As the name implies, high and low voltage switch cabinets are equipment connected to high-voltage or low-voltage cables. Generally, power supply bureaus and substations use high-voltage cabinets, and then step down through transformers and then go to low-voltage cabinets. From the low-voltage cabinet to the power distribution box, there ...
