Abstract

The invention relates to the technical field of switch cabinet main bodies, in particular to a switch cabinet for arcing and pressure relief. The switch cabinet comprises a pressure relief cabinet andat least one switch cabinet main body which are arranged side by side, a pressure relief chamber is arranged in the switch cabinet body, and a pressure relief opening communicated with the pressure relief chamber is formed at the lower portion of the side face of the switch cabinet body. The pressure relief cabinet comprises a cabinet body and a plurality of filtering assemblies, the lower part of the side surface of the cabinet body is provided with a connecting port, and the top is provided with a discharge port communicated with the external environment. The cabinet body is internally provided with a pressure relief channel bypassing the interior space of the cabinet body, the two ends of the pressure relief channel are respectively communicated with the connecting port and the discharge port, and the cabinet body is arranged at the side part of the switch cabinet main body. The connecting port is communicated with the pressure relief chamber, and the multiple filtering assembliesare arranged in the pressure relief channel at intervals. A melt conveyed from the pressure relief chamber is filtered out by the filtering assembly and is left in the cabinet body, so that the melt cannot be sprayed to the people and objects below the melt.

Description

technical field [0001] The invention relates to the technical field of switch cabinets, in particular to a switch cabinet used for arcing and pressure relief. Background technique [0002] As a kind of electrical equipment, switchgear is mainly used for switching, controlling and protecting electrical equipment during the process of power generation, transmission, distribution and power conversion in the power system. Once the arcing fault such as internal short circuit occurs during the operation of the switchgear and the gas and burnt melt produced by the arcing fault cannot be discharged in time, it is easy to cause injury to the on-site operators and endanger the personal safety of the on-site operators. [0003] Such as figure 1 and figure 2 As shown in Fig. 1 , the measures for the common medium-voltage gas-insulated switchgear 1′ on the market to deal with the gas and burned melt produced by internal arcing faults are basically to introduce the gas and burned melt ...
