The invention relates to a switch cabinet and an interlocking mechanism thereof. The switch cabinet comprises a cabinet body, wherein the cabinet body is equipped with an upper door, a lower door andan interlocking mechanism for realizing the sequential opening and closing of the upper and lower doors, the upper door is provided with a bolt, the interlocking mechanism comprises an interlocking plate arranged on the cabinet body in a manner of moving up and down, the interlocking plate is provided with a bolt adapting portion adapted to the bolt, and the bolt adapting portion and / or the bolt are / is each provided with an inclined matching surface used for pushing the interlocking plate to move in the up and down direction when the upper door is closed; the interlocking mechanism further comprises a transmission member arranged on the cabinet body in a manner of moving in the front-rear direction, a pushing member is arranged on the transmission member or the lower door, the pushing member comprises a stopping surface used for being in stopping cooperation with the interlocking plate in the front-rear direction so as to prevent the lower door from pushing the transmission member, andthe interlocking plate has a stopping position and an avoidance position on the up and down moving stroke; and the interlocking mechanism further comprises a locking buckle, the transmission member is connected with the locking buckle, and the locking buckle has an upper locking position and an unlocking position at which the interlocking plate returns to an initial state when the lower door is opened.
Description
technical field [0001] The invention relates to the technical field of electrical cabinets, in particular to a switch cabinet and an interlocking mechanism thereof. Background technique [0002] Power equipment with a higher voltage level must have safety protection devices to ensure the safety of operators, such as switchgear, the rear door panel is usually designed as an upper and lower door structure, and only the lower door operation is performed during normal maintenance, ignoring the upper door. Whether it is locked or not, the operator will have the risk of accidentally opening the door and entering the live compartment. In order to ensure safety, the door opening sequence of the switchgear must be controlled: only the upper door can be closed before the lower door can be closed, otherwise the lower door must be opened before the upper door can be opened. [0003] Therefore, it is very necessary to propose an interlock mechanism capable of controlling the door openin...
