Embodiment 1

[0070] This embodiment provides a miniature circuit breaker control device, such as Figure 1-4 shown, including

[0071] The housing 3, and the motor 1, the rotating wheel 34, the transmission mechanism, the screw rod 24, the slider 25 and the control assembly arranged in the housing 3;

[0072] The motor 1 is arranged in the casing 3;

[0073] The transmission mechanism is connected with the motor 1 through transmission;

[0074] Screw rod 24 is driven by the transmission mechanism to rotate;

[0075] The slider 25 is arranged on the screw rod 24. When the screw rod 24 rotates, it can make a linear displacement along the screw rod 24. The slider 25 has a home position, an opening position and a closing position on the screw rod 24. gate position;

[0076] The control component is connected with the motor 1, and controls the rotation of the motor 1 according to the opening and closing control signal, thereby driving the screw 24 to rotate, and making the slider 25 do a li...

Embodiment 2

[0122] This embodiment provides a miniature circuit breaker control device, 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,

[0123] The opening drive mechanism in this embodiment includes:

[0124] A driving block 26 is arranged on the slider 25;

[0125] An arc-shaped through hole 361 is opened on the housing 3;

[0126] The tripping rod 36 passes through the through hole 361 and extends into the circuit breaker for triggering the tripper in the circuit breaker 9;

[0127] The tripping driver 42 is rotatably arranged on the housing 3 and is used to move the tripping rod 36 in the through hole 361;

[0128] The tripping rod 36 moves in the through hole 361 and has an initial position for releasing the tripper in the circuit breaker 9 and a trigger positi...

Embodiment 3

[0145] This embodiment provides a method for controlling a miniature circuit breaker using the miniature circuit breaker control device described in embodiment 1 or 2, including the following instruction control steps:

[0146] S1: The communication module 83 receives the opening and closing control signal and sends it to the controller 80, and the controller 80 controls the operation of the motor 1 according to the received control command to drive the circuit breaker to open or close;

[0147] S2: After the miniature circuit breaker completes opening or closing, the controller 80 controls the motor 1 to stop running;

[0148] S3: The controller 80 controls the running direction of the motor 1 according to the on-off state of the main circuit obtained by the detection module 81 so that the slider 25 returns to the original position.

[0149] The slider 25 is controlled by the controller 80 to return to the original position after driving the miniature circuit breaker to open ...

Abstract

The invention provides a miniature circuit breaker control device. Through movement of a sliding block on a screw rod, a switch-off driving mechanism and a switch-on driving mechanism are respectively driven to complete switch-off and switch-on operations on a circuit breaker; after the switch-off and switch-on operations are completed, the sliding block returns to an original position, and a transmission relation with the switch-off driving mechanism or the switch-on driving mechanism is disconnected; since the transmission relation is disconnected, an internal part of the miniature circuit breaker control device cannot stop the action of a switch-off and switch-on mechanism of the miniature circuit breaker any longer, thus, a handle of the miniature circuit breaker still can be manually operated to achieve switch-off and switch-on after the switch-off and switch-on operations of the miniature circuit breaker are controlled. With the miniature circuit breaker control device provided by the invention, the manual switch-off and switch-on still can be fulfilled on the condition of a fault occurs in the miniature circuit breaker control device without affecting original manual control of the miniature circuit breaker, and the safety performance is improved. Moreover, the invention also provides a method applying the above miniature circuit breaker control device to control the miniature circuit breaker.

Description

technical field [0001] The invention relates to the technical field of electrical switches, in particular to a miniature circuit breaker control device and a method for controlling a circuit breaker using the device. 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 operating m...
