Abstract

The invention discloses an extraction type function unit for a switch cabinet. The extraction type function unit comprises a fixing cabinet body and a mobile drawer. The fixing cabinet body comprises an upper layer partition plate, a lower layer partition plate, a cabinet base plate and a door panel. The upper layer partition plate and the lower layer partition plate are arranged in a matching and corresponding mode. The door panel is provided with a divide-shut brake hand shank. Two side ends of the upper partition plate and two side ends of the lower layer partition plate are respectively provided with sliding chutes with inward notches. The mobile drawer comprises a base plate, a breaker fixedly arranged on the base plate and side plates respectively fixed on two sides of the base plate. The side plates are provided with sliding rails matched with the sliding chutes. The mobile drawer is arranged in the fixed cabinet body in a movable mode through matching of the sliding rails and the sliding chutes. The function unit is standardized in structure and modularized in unit, is provided with a reliable mechanical interlocking mechanism, and is safer, more reliable, and more convenient to operate when used by a user.

Description

technical field [0001] The invention relates to a withdrawable functional unit for a switch cabinet. 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 power distribution equipment should have double-circuit outlets, and the "connection positi...
