In an embodiment, the present embodiment provides an opening mechanism of a remote-controlled circuit breaker, which is mainly used for driving an emergency opening tripping button of the circuit breaker to release the charged state of the circuit breaker. Specifically, the emergency opening mechanism of the circuit breaker comprises a main body and a remote controller. The main body is used for being installed on a breaker cabinet, and the remote controller is used for remotely controlling the main body to perform pushing operation.
Specifically, the main body comprises a plug 4, a driving unit 3, a control unit and a wireless signal receiver. Wherein the driving unit 3 is used for pushing the emergency opening tripping button 5 of the circuit breaker. Specifically, the driving unit 3 may drive the plug 4 to rotate to push the emergency opening tripping button 5, or drive the plug 4 to move linearly to push the emergency opening tripping button, which may be specifically set as required. If a telescopic pneumatic cylinder can be adopted, when the telescopic pneumatic cylinder is used, an air pump connected with a rodless cavity of the telescopic pneumatic cylinder is started, or a switch valve between the rodless cavity of the telescopic pneumatic cylinder and an air source is opened, so that high-pressure air enters the rodless cavity of the telescopic pneumatic cylinder, and a piston rod is pushed to extend out. The driving unit 3 can also be a motor, when the device is started, a power supply is connected with a power supply end of the motor to supply power, and the motor rotates to push the ejector head 4 which is driven by a motor spindle to move, so that pushing is realized. Specifically, how the driving unit 3 drives the emergency opening and tripping button of the circuit breaker can be set according to requirements. In particular, in order to enable better precision driving, it is preferred that the driving unit 3 is an electric push rod.
The control button of the remote controller can send a brake separating signal to the wireless signal receiver after being pressed, and the control unit can control the driving unit 3 to drive the ejector 4 to move so as to push the emergency brake separating tripping button 5 of the circuit breaker after the wireless signal receiver receives the brake separating signal. After a control button of the remote controller is pressed, a control signal, namely a brake-separating signal is generated, the brake-separating signal is wirelessly transmitted to a wireless signal receiver through a wireless signal transmitter on the remote controller, the wireless signal receiver receives the brake-separating signal and then transmits the brake-separating signal to the controller, and the controller forms corresponding control response operation after receiving the brake-separating signal so as to start the driving unit 3, for example, after receiving the brake-separating signal, the controller controls the switch valve to be opened or controls an electromagnetic power switch between a power supply and the driving unit 3 to be closed. It should be noted that, the wireless signal transmitter and the wireless signal receiver may transmit signals wirelessly, specifically, may be a bluetooth-based transmission signal, a WiFi-based transmission signal, and the like.
In the remote control circuit breaker opening mechanism, when in use, the main body is fixedly arranged on a circuit breaker cabinet, and the top head 4 on the driving unit 3 on the opening mechanism is aligned with the circuit breaker emergency opening tripping button, so that when the driving unit 3 drives the top head 4 along the driving direction, the top head 4 can push the circuit breaker emergency opening tripping button. Then, at a remote position, the remote controller remotely starts the driving unit 3 by pressing a control button on the remote controller to drive the plug 4 to complete the operation. This remote control circuit breaker separating brake mechanism has set up the remote controller to and carry out wireless signal transmission's wireless transmitter and wireless signal receiver between remote controller and controller, so that operating personnel can leave behind the safe position as required, at the execution operation, and because wireless transmission, so little to staff's restriction, make easy operation convenient. In conclusion, the remote control breaker opening mechanism can effectively solve the problem that the emergency opening tripping button of the close-range operation breaker is unsafe.
Further, in order to improve controllability, it is preferable that the control buttons on the controller include a forward button, a backward button, and a pause button to control the driving unit 3 to advance, retreat, and pause, respectively. Namely: when the forward button is pressed, the driving unit 3 drives the ejector 4 towards the direction close to the emergency brake-separating tripping button of the circuit breaker; when the pause button is pressed, the plug 4 is kept at the current position and stops moving forwards or backwards; and after the back button is pressed, the driving unit 3 drives the top head 4 towards the direction far away from the emergency opening tripping button of the circuit breaker, so that the emergency opening tripping button of the circuit breaker can be reset.
Further, in order to better transmit the wireless signal between the wireless signal transmitter and the wireless signal receiver, it is preferable that the wireless signal is transmitted between the remote controller and the wireless signal receiver through the superheterodyne receiving module. The superheterodyne receiving module is adopted to realize high remote control sensitivity and long remote control distance, and the remote control distance can reach 50 meters under the condition of no obstacle. Specifically, the remote controller can optionally select two dc power supplies of 12V/24V with different voltage levels, and preferably select the driving unit 3 and the controller on the host computer, and can also optionally select two dc power supplies of 12V/24V with different voltage levels.
For more convenient use, it is preferred here that the body comprises a mounting 1, the mounting 1 being provided with a battery for powering said drive unit 3, control unit and said wireless signal receiver. So that an external power supply is not needed, and the operation is simpler and more convenient. Specifically, the battery may be a rechargeable battery or a non-rechargeable battery. Specifically, a battery case may be provided in the mount 1.
Specifically, if the mounting seat 1 includes a mounting groove for placing the battery, the mounting seat further includes a slot cover 2 covering the outside of the mounting groove, and the slot cover 2 is screwed to the mounting seat 1. So that it can be opened through the slot cover 2 to facilitate the discharge of the battery. For convenience of operation, it is preferable that the slot cover 2 is provided with a handle so that the slot cover 2 can be operated by the handle when being removed, and the entire main body can be operated by the handle when being removed. So that the operation is simple and convenient.
Further, in consideration of remote control, it is difficult to intuitively obtain the degree of remote control, and in order to avoid damage to the driving unit 3 or the emergency opening tripping button of the circuit breaker caused by excessive pushing, it is preferable that a pressure sensor is provided at the plug 4, wherein the control unit stops controlling the driving unit 3 to advance after a value detected by the pressure sensor is greater than a predetermined value. Specifically, a camera head may be disposed on the host machine for shooting the pushing state of the plug 4, a display may be disposed on the remote controller, and the remote controller and the controller may establish a wireless data connection so that a shot image of the camera head may be wirelessly transmitted to the remote controller and displayed on the display.
