Switch cabinet

Abstract

The invention discloses a switch cabinet. The switch cabinet comprises a cabinet body and a door body, wherein a locking device is arranged between the cabinet body and the door body, a cable chamber, an instrument chamber, a bus chamber and a circuit breaker chamber are arranged in the cabinet body, the circuit breaker chamber and the bus chamber are both provided with pressure relief passages, grounding bars are arranged at the lower part inside of the cabinet body, insulation covers are arranged outside the grounding bars, a plurality of busbars are arranged in the bus chamber, contact boxes are arranged outside the busbars and comprise contact box bodies, fixed seats are arranged in the contact box bodies, and less than or equal to 4 umbrella skirts are arranged on the outer walls of the middle parts of the contact box bodies. The switch cabinet has the advantages that the switch cabinet occupies relatively small space, is easy to move, and can stand a high-voltage impact of 95kV, and the insulativity and the arcing performance inside the cabinet switch are improved.

Description

technical field [0001] The invention relates to the technical field of power transmission equipment, in particular to a switch cabinet. Background technique [0002] At present, with the progress of society, the requirements for electrical equipment are getting higher and higher, especially in areas with high altitudes and frequent warm and humid winds, condensation often occurs, and such areas have higher requirements for the insulation of switchgear. [0003] The technical problems existing in the existing switchgear are reflected in the following aspects: 1. The volume is large and takes up space; 2. The peak value of the high-voltage shock is 75kV, and it is difficult to deal with the impact of the high voltage greater than 75kV; 3. The insulation performance of the conductor installed inside the switchgear Poor, 4. The current switchgear is not equipped with a pressure relief channel, and the arcing performance needs to be improved; 5. The resistance value of the busbar...
