Abstract

The invention discloses a switch cabinet mechanical interlocking matched set, which comprises a program lock and an interlocking piece. The program lock and the interlocking piece are arranged in a cabinet body and fixedly connected with each other; the cabinet body is provided with a breaker, a breaker chassis truck is arranged below the breaker and provided with a keyed end; the interlocking piece is movably connected with the program lock through a program lock pin; the interlocking piece comprises a linkage part, a rotating main shaft and a stop part which are mutually connected; the linkage part is movably connected with the program lock through the program locking pin; the linkage part comprises upper and lower linkage plates and a main shaft linkage blade; the upper and lower linkage plates comprise a plate bottom side, a linkage plate side and a fixed plate side which are vertical to one another; the stop part comprises a main shaft driving block, a push plate and a stopping pad block; the push plate comprises a wedged plate and a push rod; and the stopping pad block is provided with a thickening pad block. The switch cabinet mechanical interlocking matched set has the advantages of high reliability, high replaceability, simple structure, convenient operation and long service life.

Description

technical field [0001] The invention relates to a switch cabinet interlock kit, in particular to a switch cabinet mechanical interlock kit, which is particularly suitable for the mechanical interlock of two or more power sources in a high-voltage complete switch cabinet. Background technique [0002] In the existing production process of switchgear, especially in the production process of high-voltage complete switchgear, when more than two power supply lines are involved, it is inevitable to solve the mechanical interlocking problem of two or more power supplies , the traditional solution is often to install the program lock on the side of the matching circuit breaker, and then make a simple measurement on the side panel of the circuit breaker room in the cabinet and punch holes as the locking point of the program lock. [0003] The Chinese patent authorization announcement number is CN201038611Y, and the utility model patent whose authorization announcement date is March 1...
