Abstract

The invention provides a switch structure. The switch structure comprises a shell; an A phase pole column, a B phase pole column and a C phase pole column, the A phase pole column, the B phase pole column and the C phase pole column are arranged above the shell at intervals; the switch structure further comprises: an operating mechanism arranged below the shell, wherein an operating side of the operating mechanism is located on one side where a side face of the shell is located, an output end of the operating mechanism is in driving connection with a B phase pull rod of the B phase pole column, and the up and down movement of the output end drives the up and down movement of the B phase pull rod; and a transmission mechanism used for connecting the B phase pull rod with an A phase pull rod of the A phase pole column and a C phase pull rod of the C phase pole column, wherein the transmission mechanism is driven by the B phase pull rod to drive the A phase pull rod and the C phase pull rod to move up and down together with the B phase pull rod. The technical scheme of the invention effectively solves the problem of poor mechanical property coordination of a circuit breaker resulting from that the operating mechanism is located on the side face of a primary loop in the prior art.

Description

technical field [0001] The invention relates to the technical field of electrical equipment, in particular to a switch structure. Background technique [0002] Currently, if figure 1 As shown, the circuit breaker includes frame 1 and three-phase poles A, B, and C of the primary circuit 2. The frame 1 has a closing energy storage operating mechanism and an opening operating mechanism, and the three-phase poles of A, B, and C of the primary circuit 2 The poles are arranged longitudinally, and the closing energy storage operating mechanism and the opening operating mechanism simultaneously perform opening and closing operations on the A, B, and C three-phase poles through a pair of main crank arms 3 . [0003] Since the closing energy storage operating mechanism and the opening operating mechanism are located on the side of the primary circuit 2, the closer to the closing energy storing operating mechanism and the opening operating mechanism, the faster the closing speed, open...
