Abstract

The invention relates to a misoperation prevention interlocking device of a low-voltage drawer-type switch cabinet, which comprises an interlocking control handle, an interlocking connecting lever, a hanging pin, a lockpin, a lockpin bracket, a wire-incoming plug operating hole and a lockpin hole; the interlocking control handle is sleeved at the upper end of the interlocking connecting lever, and the lower end of the interlocking connecting lever is connected with the end of the lockpin through the hanging pin; the lockpin bracket is arranged in the middle of the lockpin, and the lockpin can move on the lockpin bracket through a reciprocated way; the lockpin hole is arranged at the top end of the lockpin, namely, the side of the main wire-incoming plug operating hole; and when a wire-incoming plug is in the position of complete splicing, the top end of the lockpin is just locked in the wire-incoming plug operating hole through the lockpin hole. The invention remedies the defects of the prior GEAPLUS 2.0 MCC low-voltage drawer-type switch cabinet and provides the misoperation prevention interlocking device which has simple structure, complete function and convenient use, the successful operation can be ensured when operation procedures are right; the operation is unsuccessful when operation procedures are wrong, and the accidents can be prevented from happening effectively.

Description

【Technical field】 [0001] The present invention relates to an anti-misoperation interlocking device for low-voltage switch cabinets in power supply equipment, specifically, an anti-misoperation interlocking device for low-voltage drawer-type switch cabinets, especially a low-voltage drawer-type switch dedicated to GEAPLUS2.0MCC The anti-misoperation interlocking device of the cabinet. 【Background technique】 [0002] GEAPLUS 2.0MCC low-voltage switchgear is an imported low-voltage switchgear. In its drawer cabinet, the power supply circuit is mainly composed of a busbar, an incoming plug that can be separated or plugged independently, a circuit breaker, an outgoing plug that moves synchronously with the drawer, and an outgoing line. Socket composition. When the power supply drawer unit is in the working position and the circuit breaker is closed and running, if there is no interlock device, it is easy to cause misoperation such as the separation of the incoming plug with the ...
