A kind of automatic opening and closing device and method using inner shaft transmission

Abstract

The invention provides an automatic switching-out and switching-on device utilizing an inner shaft for transmission and a method of the automatic switching-out and switching-on device. The automatic switching-out and switching-on device comprises a circuit breaker and a control module, wherein the control module comprises a stepping motor, the transmission inner shaft, a rotating disc, bosses, a worm wheel, a worm and control circuit, and the control module is connected with the circuit breaker via the transmission inner shaft. The method includes a switching on method and a switching out method. The inner shaft is adopted to drive the circuit breaker for switching out and switching on, and closing synchronism of contacts of the circuit breaker is better. A switching-out and switching-on transmission system is provided with en enclosed structure, so that solid grains are prevented from entering to cause shutdown of a mechanism. The automatic switching-out and switching-on device is provided with a state indicating function, so that a work state of the circuit breaker can be directly displayed, and a user is enabled to see if the circuit breaker works normally or not clearly. The automatic switching-out and switching-on device is provided with a switching-on preventing function, so that misoperation of the circuit breaker is effectively prevented. The automatic switching-out and switching-on device is also provided with a mode switching function which supports the user to control whether automatic switching on is needed or not according to personal conditions.

Description

technical field

[0001] The invention relates to a circuit breaker control device, in particular to an automatic opening and closing device and a method thereof driven by an inner shaft. Background technique

[0002] The circuit breaker is a load device between the power supply and the load unit to protect the motor, transformer and transmission line. Used to protect power distribution circuits against arcing faults, ground faults, short circuit faults and / or overloads.

[0003] Circuit breakers are widely used in all walks of life. The inventors have done a lot of research and observed that the transmission device between the traditional automatic closing circuit breaker motor and the circuit breaker is relatively simple, the stability is not strong, and there is a relatively large gap. Security risks. The entry of solid particles causes the mechanism to be stuck, affecting the function of opening and closing. Contents of the invention

Embodiment

[0053] A kind of automatic pulling and closing method that adopts inner shaft transmission of the present invention is specifically as follows:

[0054] Closing process:

[0055] The level signal jumps from 0V to 220V;

[0056] The internal mechanism of the control module drives the triangular shaft to rotate forward until the circuit breaker is closed;

[0057]The internal closing mechanism reverses an angle to return the circuit breaker to a trippable state.

[0058] Winding up process:

[0059] The level signal jumps from 220V to 0V;

[0060] The internal mechanism of the control module drives the triangular shaft to reversely rotate at a certain angle, and the circuit breaker is switched on;

[0061] At this time, the circuit breaker should not be able to pass manual closing (anti-closing protection).

[0062] Closing allows:

[0063] In manual mode, the level signal jumps from 0V to 220V;

[0064] The internal mechanism of the control module drives the triangular s...
