Description

technical field [0001] The invention relates to a combined switch cabinet. Background technique [0002] The main function of the switchgear is to open and close, control and protect electrical equipment during the process of power generation, transmission, distribution and power conversion in the power system. The components in the switchgear mainly include circuit breakers, isolating switches, load switches, Operating mechanism, transformer and various protection devices, etc. There are many classification methods of switch cabinets. For example, according to the installation method of circuit breakers, it can be divided into removable switch cabinets and fixed switch cabinets; or according to the different cabinet structures, it can be divided into open switch cabinets, metal-enclosed switch cabinets, and metal Closed armored switchgear; according to different voltage levels, it can be divided into high-voltage switchgear, medium-voltage switchgear and low-voltage switch...
