Embodiment 1

[0076] This embodiment provides a miniature circuit breaker control structure, such as Figure 1-4 shown, including

[0077] A motor 1, a rotating wheel 34, a transmission mechanism and a control assembly arranged in a housing 3;

[0078] motor 1;

[0079] The transmission mechanism is connected with the motor 1 through transmission;

[0080] The opening drive mechanism is used to drive the opening of the miniature circuit breaker;

[0081] The closing drive mechanism is used to drive the miniature circuit breaker to close;

[0082] A control component, connected to the motor 1, for controlling the rotation of the motor 1;

[0083] The control component controls the transmission mechanism to establish a transmission relationship with the opening drive mechanism or the closing drive mechanism when the circuit breaker is opened or closed, and when the circuit breaker completes the opening or closing operation Then drive the transmission mechanism to break away from the tran...

Embodiment 2

[0134] This embodiment provides a miniature circuit breaker control structure, which is an improvement on the basis of Embodiment 1. The difference between this embodiment and Embodiment 1 is that the structure of the opening drive mechanism is different and the structure and function of the control assembly different, such as figure 2 as shown,

[0135] The opening drive mechanism in this embodiment includes:

[0136] A driving block 26 is arranged on the slider 25;

[0137] The tripping rod 36 passes through the arc-shaped through hole 361 provided on the housing 3, and extends into the circuit breaker for triggering the tripper in the circuit breaker 9;

[0138] The tripping driver 42 is capable of rotating, and is used to move the tripping rod 36 in the arc-shaped through hole 361;

[0139] The tripping rod 36 moves in the arc-shaped through hole 361 and has an initial position for releasing the tripper in the circuit breaker 9 and a trigger position for triggering the...

Embodiment 3

[0156] This embodiment provides a miniature circuit breaker control device, such as Figure 1-3 As shown, it includes a housing 3 and the MCB control structure set in the housing 3 as described in Embodiment 1 or 2.

[0157] Since the MCB control device of this embodiment has the MCB control structure of Embodiment 1 or 2, it also has the advantages described in Embodiment 1 or 2.

Abstract

The invention provides a miniature circuit breaker control structure. A control component controls a transmission mechanism to establish transmission relation with a switching-off driving mechanism or a switching-on driving mechanism in switching-off operation or switching-on operation on a circuit breaker, and drives the transmission mechanism to disengage the transmission relation with the switching-off driving mechanism or the switching-on driving mechanism after the circuit breaker finishes the switching-off operation or the switching-on operation. Because the transmission relation is disengaged, the internal components of the miniature circuit breaker control structure can not prevent the action of the switching-off mechanism or the switching-on mechanism of the miniature circuit breaker, so that after the miniature circuit breaker is controlled to carry out the switching-off operation or the switching-on operation, the handle of the miniature circuit breaker can still be manually operated to realize the switching-off operation or the switching-on operation. The miniature circuit breaker control structure provided by the invention does not affect the manual control way of the original miniature circuit breaker and can still be manually switched-off and switched-on when having faults, thereby improving the safety performance.

Description

technical field [0001] The invention relates to the technical field of electrical switches, in particular to a miniature circuit breaker control structure and a miniature circuit breaker control device including the structure. Background technique [0002] The miniature circuit breaker is the most widely used terminal protection device in the building electrical terminal power distribution device. The miniature circuit breaker is composed of opening and closing mechanism, contacts, protection devices (various releases and current heating components), arc extinguishing system, etc. [0003] Its working principle is: use the protection device (release) and the current heating component to realize overload and short circuit protection. When the current passing through the coil in the current heating component is greater than the set current value, the moving iron core of the electromagnetic release will act , Push the striking lever to hit the operating mechanism, unlock the o...
