Abstract

The invention discloses a switch cabinet pull-out type functional unit with a sealing structure. The switch cabinet pull-out type functional unit with the sealing structure comprises a fixed cabinet body and a moving drawer. The fixed cabinet body comprises an upper-layer spacing board, a lower-layer spacing board, a cabinet body bottom board and a door face board, wherein the upper-layer spacing board and the lower-layer spacing board are arranged in a matched corresponding mode, a switch-on-off handle is arranged on the door face board, a sealing strip is arranged on an inner side frame of the door face board, two side ends of the upper-layer spacing board are respectively provided with a sliding groove, an opening of each groove faces inward, two side ends of the lower-layer spacing board are respectively provided with a sliding groove, and an opening of each groove faces inward. The moving drawer comprises a bottom board, a circuit breaker and side boards, wherein the circuit breaker is fixed on the bottom board, the side boards are fixed at two sides of the bottom plate respectively, sliding rails matched with the sliding grooves are arranged on each slide board, and through matching between the sliding rails and the sliding grooves, the moving drawer can be movably arranged in the fixed cabinet body. The switch cabinet pull-out type functional unit with the sealing structure is standardized in structure, modularized in unit, and provided with the reliable mechanical interlocking mechanism. Therefore, the switch cabinet pull-out type functional unit with the sealing structure is safer, more reliable, and more convenient to operate when being used by a user.

Description

technical field [0001] The invention relates to a withdrawable functional unit of a switch cabinet, in particular to a withdrawable functional unit of a switch cabinet with a sealed structure. Background technique [0002] Withdrawable functional units have been widely used in the output part of low-voltage switchgear, mainly because of their good interchangeability. When a functional unit fails, use the same type of spare drawer to replace the faulty drawer. The use of the feed-out loop is restored in a short time, and the efficiency is improved. At present, the domestic mainstream products are GCK, GCS and MNS imitated by ABB company. There is a certain gap in performance, it is inconvenient to replace functional units, the protection level is not high, and it is not suitable for use in harsh environments. The test location is not isolated from the connection location, which poses a safety hazard. [0003] According to market research, the withdrawable functional unit of...
