Abstract

The invention disclosed by the invention belongs to the technical field of operation of circuit breakers in central cabinets, and specifically relates to an interlocking mechanism for operating trolleys of circuit breakers in central cabinets. The right side of the top of the trolley mounting plate is connected with a buckle lock frame by bolts, and a connection reinforcing rib is sleeved between the fixed frame and the buckle lock frame, and an inner telescopic rod is plugged into the inner cavity of the connection reinforcement rib. The right side wall of the inner telescopic rod is integrally formed with a limited block. The present invention installs a connecting reinforcing rib on the trolley mounting plate. When installing the central cabinet, the connecting reinforcing rib is along the middle lock hole on the central cabinet. Align and put in, after the center cabinet is fixed by pulling out the pull block, loosen the pull block to realize the locking of the connecting block, and complete the snap connection with the connecting rib, and directly turn the pull block to complete the locking effect , Improve the fixing strength of the center cabinet.

Description

technical field [0001] The invention relates to the technical field of operation of a circuit breaker in a central cabinet, in particular to an interlocking mechanism for an operating trolley of a circuit breaker in a central cabinet. Background technique [0002] With the vigorous development of my country's electric power industry, at present, the KYN-28 cabinet type accounts for about 1 / 4 in the field of power transmission and distribution in my country, which is quite a huge proportion. Usually the KYN-28 cabinet type is equipped with an ordinary running trolley as standard. Due to the low structural strength of the trolley design, unreliable interlocking, light body, and high center of gravity, it results in low efficiency, high labor intensity, poor interchangeability, and safety and reliability. Low; circuit breaker drop damage and personal injury often occur, causing certain economic losses and safety risks to the majority of users; therefore, an interlocking mechani...
