Explosion-proof safe inflatable ring main unit

Abstract

The invention discloses an explosion-proof safe inflatable ring main unit which comprises a cabinet body and a cabinet door, wherein a gas conveying cavity is formed in the side wall of the cabinet body, a gas inlet and a gas outlet which are communicated with the gas conveying cavity are formed in the inner wall of the cabinet body, and a gas supply assembly is arranged in the gas conveying cavity; and a water storage cavity is formed in the bottom part of the cabinet body, a first water conveying cavity communicated with the water storage cavity is formed in one side of the gas conveying cavity, and a first push plate matched with the air supply assembly is arranged in the water storage cavity. Water flow is used for cooling gas in the cabinet body, so that the temperature in the cabinet body is reduced, elements in the cabinet body are prevented from being affected by high temperature, and the service life of the elements is guaranteed.

Description

technical field [0001] The invention belongs to the technical field of ring network cabinets, in particular to an explosion-proof and safe inflatable ring network cabinet. Background technique [0002] The ring network cabinet is a group of transmission and distribution electrical equipment, which is installed in a metal or non-metal insulated cabinet or made into an assembled interval ring network power supply unit. Its core part uses load switches and fuses, and has a simple structure and small size. , low price, can improve power supply parameters and performance and power supply security and other advantages. [0003] The inflatable ring network cabinet is generally filled with sulfur hexafluoride gas. In order to avoid the leakage of sulfur hexafluoride gas, the inflatable ring network cabinet generally adopts a sealed structure. The ring network cabinet itself will generate a lot of heat when it is working. The sealed ring network cabinet The heat cannot be dissipated...

AI Technical Summary

Problems solved by technology

[0003] The inflatable ring network cabinet is generally filled with sulfur hexafluoride gas. In order to avoid the leakage of sulfur hexafluoride gas, the inflatable ring network cabinet generally adopts a sealed structure. The ring network cabinet itself will generate a lot of heat when it is working. The sealed ring network cabinet The heat cannot be dissipated, causing the heat in the ring network cabinet to continue to increase, causing damage to the equipment in the ring network cabinet and affecting the service life of the ring network cabinet; the existing inflatable ring network cabinets are generally equipped with windproof glass so that the staff can When the protective cabinet is opened, the working condition of the inflatable ring network cabinet can be observed through the windproof glass. The outside of the windproof glass is exposed, and dust will accumulate after a long time, which will affect the visibility of the glass.
