Abstract

The invention discloses a reclosure mechanism of a disconnector. The reclosure mechanism of the disconnector comprises an electromagnetic mechanism, a transmission mechanism and an opening/reclosure execution mechanism. The electromagnetic mechanism comprises a closure electromagnetic device (2) with a closure iron core (1), and an opening electromagnetic device (4) with an opening iron core (3). The transmission mechanism comprises a transmission shaft (5), wherein the transmission shaft (5) is in linkage with the closure iron core (1) and the opening iron core (3), thereby rotating under driving the closure iron core (1) or the opening iron core (3). The opening/reclosure execution mechanism comprises a shifting rod (32) capable of driving opening and closure motions of a handle of the disconnector, the shifting rod moves under driving the transmission shaft (5). An electromagnetic protection device is used for connecting and disconnecting current of the electromagnetic mechanism. The reclosure mechanism of the disconnector is simple in structure, and has a good opening/reclosure effect.

Description

Technical field [0001] The invention relates to the technical field of circuit breakers, in particular to a circuit breaker reclosing mechanism capable of realizing manual and electric integrated opening and closing of the circuit breaker. Background technique [0002] At present, the manual and electric integrated reclosing mechanism of smart circuit breakers on the market mainly has two structural forms, one is a linkage mechanism, and the other is a gear and rack coordination mechanism. [0003] The linkage mechanism drives the linkage rod through the rotation of the motor output shaft, the linkage rod pulls the transmission rod, and the other end of the transmission rod is fixed on the opening and closing handle of the circuit breaker to drive the opening and closing handle to move forward and backward. The advantage of this mechanism is that the structure is relatively simple, but the disadvantage is that manual closing and opening cannot be realized without adding other devic...
