Bypass operations can be used without power outages and to avoid the safety risks of disconnecting and connecting wires under load.

Some three-phase bypass load switches are too long and cannot be fixed on the pole, which is not conducive to on-site live operations. During on-site operations, multiple people are required to participate in the wiring of the three-phase bypass cable, which is inconvenient and increases the difficulty of construction.

[0031] Figure 3 It is a schematic diagram of the structure of the opening and closing control component in an embodiment of the present invention. DETAILED DESCRIPTION

[0032] In order to enable those skilled in the art to better understand the technical solutions in the present invention, the technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work should fall within the scope of protection of the present invention.

[0033] like Figure 1 and Figure 2 As shown, the embodiment of the present invention provides a single-phase bypass load switch device with a quick plug-in structure, comprising a housing 1, an arc extinguishing chamber 4 is arranged in the housing 1, the arc extinguishing chamber 4 is provided with a static contact and a moving contact, and a control mechanism 11 is also arranged in the housing 1; a quick plug-in connector is installed on the housing wall; The quick-plug connector includes a first quick-plug connector 7 and a second quick-plug connector 6; The first quick-plug connector 7 is connected to the static contact of the arc extinguishing chamber, the second quick-plug connector 6 is connected to the moving contact of the arc extinguishing chamber, and the moving contact of the arc extinguishing chamber is connected to the control mechanism through the insulating pull rod 10; The control mechanism includes a controller and a switch-on and switch-off control assembly; the lower part of the switch-on and switch-off control assembly is fixed on the inner wall of the housing; the switch-on and switch-off control assembly is connected to the insulating pull rod and the controller respectively; A detection module for detecting the state of the cable connected to the single-phase bypass load switch device is also provided in the housing. The detection module is connected to the controller, and the controller controls the action of the opening and closing control component according to the detection information of the detection module.

[0034] When a single-phase bypass load switch device needs to be installed, first fix the housing of the device in a suitable position. Then, connect the device to the external cable through the quick-plug connector. The first quick-plug connector is connected to the static contact of the arc extinguishing chamber, and the second quick-plug connector is connected to the moving contact of the arc extinguishing chamber. This quick-plug design makes the connection process simple and fast, without the need for complicated wiring work. After the device is connected, the detection module starts working and detects the status of the cable in real time. The detection module collects the current, voltage, temperature and other parameters of the cable through sensors and other equipment, and transmits these data to the controller for analysis.

[0035] The controller determines whether the cable status is normal based on the detection information provided by the detection module. If the cable status is abnormal, the controller will immediately send instructions to the opening and closing control component to disconnect the circuit to protect the safety of the power system. If the cable status is normal, the controller will keep the opening and closing control component in standby mode and wait for further operation instructions.

[0036] When opening and closing operations are required, the operator sends instructions to the opening and closing control component through the controller. After receiving the instructions, the opening and closing control component drives the moving contact of the arc extinguishing chamber through the insulating pull rod to perform opening and closing operations. The entire operation process is fast and accurate, ensuring the stable operation of the power system.

[0037] The single-phase bypass load switch device with a quick-plug structure proposed in the present invention realizes quick connection and disconnection between the device and external cables, as well as real-time monitoring of cable status and fault warning by introducing quick-plug connectors and detection modules, thereby greatly improving the installation efficiency, maintenance convenience and safety of the device.

[0038] In some embodiments, the first quick-plug connector 7 is connected to the static contact of the arc extinguishing chamber through the first fixed copper bar 2, and the second quick-plug connector 6 is connected to the moving contact of the arc extinguishing chamber through the second fixed copper bar 5; The moving contact of the arc extinguishing chamber is also connected with a soft connector 9; One end of the insulating pull rod is connected to the moving contact of the arc extinguishing chamber, and the other end of the insulating pull rod is connected to the opening and closing control component. The soft connector 9 is connected to the second fixed copper bus 5.

[0039] In some embodiments, Figure 3 As shown, the opening and closing control assembly includes an opening and closing pull rod 80, and the opening and closing pull rod 80 is provided with a metal disc 84, an opening coil 83 is provided on the upper side of the metal disc of the opening and closing pull rod, and a closing coil 85 is provided on the lower side of the metal disc; The bottom of the opening and closing pull rod is fixedly connected to two branch pieces with the same structure, and the two branch pieces are arranged at a set angle; The branch member includes an upper crank arm 86, a lower crank arm 87, a plug 88 and a closing buffer which are connected in sequence; the upper crank arm 86 is connected to the bottom of the opening and closing pull rod 80, one end of the closing buffer is connected to the plug, and the other end of the closing buffer is fixedly connected to the inner wall of the housing; The opening and closing control assembly also includes an opening buffer 89 fixed to the bottom of the housing. Here, the opening buffer structure is similar to the closing buffer, and also includes a buffer spring and an end cover. One end of the buffer spring of the opening buffer is connected to the end cover, and the other end is connected to a contact. When the opening and closing pull rod 80 performs the opening action and moves downward, the bottom end of the opening and closing pull rod compresses the buffer spring through the contact to achieve opening buffering.

[0040] The closing buffer includes a buffer spring 81 and an end cover 82; One end of the buffer spring 81 is connected to the plug 88 , and the other end of the buffer spring 81 is connected to the end cover 82 , and the end cover 82 is fixed on the inner wall of the housing.

[0041] Working principle: Use a push button switch or remote control switch to give the controller a signal.

[0042] When opening: the opening coil 83 is energized, and the metal disc 84 of the opening and closing rod induces a reverse current. The induced current generates an electromagnetic force in the opposite direction to the opening coil. The electromagnetic force pushes the opening and closing rod to move downward. When it moves to the bottom, the bottom of the opening and closing rod collides with the opening buffer. The opening buffer offsets the opening force, and the opening and closing control component keeps it in the opening position.

[0043] When closing the circuit breaker: the closing coil 85 is energized, and the metal disc 84 of the closing and opening lever induces a reverse current. The induced current generates an electromagnetic force in the opposite direction to the opening coil. The electromagnetic force pushes the closing and opening lever to move upward, and the closing and opening control assembly will be fixed in the closing position due to the resistance of the spring.

[0044] It should be noted here that the power module provides different voltages to the device. Usually, in order to provide sufficient current to drive the opening coil and the closing coil, a suitable DC power supply (DC Power Supply) needs to be selected. Therefore, the device also includes a power module, and the voltage and current of the power supply should be selected according to the specifications of the coil to ensure that the coil can work normally and generate sufficient electromagnetic force.

[0045] The power supply should be connected to the power input terminal of the controller. There is usually a power management module inside the controller to convert the input power into a voltage and current suitable for each component (including the opening coil and closing coil).

[0046] The controller needs to receive control signals from a push button switch or a remote control switch. These signals can be electrical signals (such as high and low level signals) or wireless signals (such as radio frequency signals). Push button switches are usually connected to the controller through wires. When the button is pressed, the level state in the circuit will change, thereby sending a control signal to the controller. The remote control switch sends signals wirelessly, and the controller needs to be equipped with a corresponding signal receiving module to receive these signals. There will be a signal processing module inside the controller to decode and process the received control signals. Based on the processing results, the controller will decide whether to send a drive signal to the opening coil or the closing coil. The controller sends drive signals to the opening coil and the closing coil through the output port. These signals are usually pulse width modulation (PWM) signals or DC voltage signals.

[0047] When the circuit breaker needs to be opened, the controller sends a drive signal to the opening coil, which energizes it and generates electromagnetic force. When the circuit breaker needs to be closed, the controller sends a drive signal to the closing coil, which also energizes it and generates electromagnetic force. The controller can also monitor the opening and closing status through components such as sensors or switches.

[0048] For example, sensors can be set at the opening buffer and closing position. When the opening and closing pull rods move to the corresponding positions, the sensors will send signals to the controller, indicating that the opening or closing operation has been completed.

[0049] The controller can further adjust the output or perform fault diagnosis based on these feedback signals. In order to ensure the safe operation of the system, the controller should also have safety protection functions. For example, when abnormal conditions such as power failure, coil overheating or sensor failure are detected, the controller should immediately cut off the output signal and issue an alarm prompt.

[0050] In some embodiments, the controller is further connected to an emergency opening button and an emergency closing button. When the controller determines the opening condition, the emergency opening button has the highest priority.

[0051] The device also includes a remote controller, and the controller is connected to a signal receiving module; The remote controller communicates with the controller via the remote control signal receiving module.

[0052] In some embodiments, the detection module includes a temperature detection unit, an input signal detection unit, and an output signal detection unit; The temperature detection unit is used to detect the temperature value in the device and send it to the controller; The input signal detection unit is arranged on the input cable connected to the quick plug-in connector of the device, and the output signal detection unit is arranged on the output cable connected to the quick plug-in connector of the device; Each signal detection unit includes a voltage detection unit and a current detection unit; the voltage detection unit is used to detect the voltage information of the corresponding cable and send it to the controller, and the current detection unit is used to detect the current of the corresponding cable and send it to the controller.

[0053] It should be noted that the controller is first initialized after startup, including memory clearing, register setting, communication interface configuration, etc. Then it performs a self-test to check whether the internal circuit, memory, communication interface, etc. are working properly. At the same time, the controller will check whether the communication connection with the temperature detection unit, input signal detection unit and output signal detection unit is successfully established.

[0054] The temperature detection unit continuously monitors the temperature value in the device and sends the temperature data to the controller. After receiving the temperature data, the controller compares it with the preset temperature threshold. If the temperature exceeds the threshold, the controller will trigger an alarm and may take protective measures, such as shutting down some functions or starting the cooling system. If the temperature is within the normal range, the controller will continue to monitor.

[0055] The input signal detection unit is set on the input cable connected to the quick plug connector of the device, and includes a voltage detection unit and a current detection unit. The voltage detection unit detects the voltage information of the input cable, and the current detection unit detects the current of the input cable. After receiving these signals, the controller performs signal processing, such as filtering, amplification, A / D conversion, etc., to obtain accurate voltage and current values.

[0056] In some embodiments, the housing adopts an integral casting structure, and the housing is provided with a front cover 102, a rear cover 103 and a top cover 101 with an opening and closing structure design; The first quick-plug connector 7 is connected to the front cover 102 by screws, the second quick-plug connector 6 is connected to the rear cover 103 by screws, and the control mechanism is arranged on the bottom plate. The front cover 102, the rear cover 103 and the top cover 101 are designed as an open-and-close structure.

[0057] In some embodiments, the device also includes a phase checker, which is respectively connected to the first quick plug-in connector and the second quick plug-in connector, and is used to check the phase of the cable connected to the first quick plug-in connector and the second quick plug-in connector, and the phase checker is connected to the controller.

[0058] In order to facilitate taking the device provided by the embodiment of the present invention, a handle 13 is provided on the housing.

[0059] In the embodiment of the present invention, a remote controller is used to send a remote signal to the controller, so that the controller controls the power supply of the opening coil or the closing coil, and then controls the opening and closing operations of the bypass load switch. An emergency opening button and a closing button are set in the control mechanism, and a power module is set inside the device to provide control power to the entire mechanism. When the external cables are respectively inserted into the device through quick connectors, the phase detector of the device will work, and it cannot be closed if they are not in the same phase. The device adopts a vacuum arc extinguishing chamber to ensure that the system can break the rated current. The device can be fixed to the live working pole with a rope or an iron chain. Setting a remote controller can remotely complete the opening and closing operations of the device.

[0060] The embodiment of the present invention further provides a single-phase bypass load switch control method with a quick plug-in structure, which is applied to the device described in the above embodiment, and the method comprises the following steps: When external cables are respectively inserted into the device through quick connectors, the phase checker of the device checks the phases of the connected cables and sends the phase check results to the controller; When the phase verification results are the same and the controller does not receive a signal from the emergency trip button, the controller receives the temperature value detected by the temperature detection unit, and compares the received temperature value with the set temperature threshold. When the temperature value is less than the set temperature threshold and the corresponding input cable voltage information exists, the controller outputs a control signal to control the opening and closing control component to complete the closing operation; When the phase verification results are different, the controller does not control the opening and closing control component to perform the closing action; When the controller receives a signal from the emergency opening button or receives an opening command signal input by the remote control, the controller outputs a control signal to control the opening and closing control components to complete the opening operation.

The execution order of each process should be determined by its function and internal logic, and should not constitute any limitation on the implementation process of the embodiment of the present invention.
