Description

Technical Field

[0001] This utility model relates to the field of low-voltage electrical technology, specifically a small reclosing circuit breaker. Background Technology

[0002] In the operation of power systems, there is a crucial technical operation called reclosing. Specifically, when an overhead line fails, relevant personnel will quickly take a series of measures to clear the fault. Within a very short time after the fault is successfully cleared, the circuit breaker will be closed again. This key operation is called reclosing. As an efficient and practical self-restoring power supply method, reclosing has been widely used in the daily operation of power systems. By executing reclosing operations in a timely manner, power supply to users can be quickly restored, minimizing the time and scope of power outages, thereby improving the reliability and stability of the entire power system. In actual operation scenarios, the method of using gear transmission and mechanical linkage for position detection has certain limitations. When the mechanical mechanism malfunctions during the closing process, the detection mechanism will find it difficult to accurately determine the closing status, which will directly affect the judgment of the actual opening and closing status of the reclosing circuit breaker.

[0003] Therefore, a small reclosing circuit breaker is needed to improve the above problems. Utility Model Content

[0004] The purpose of this invention is to provide a small reclosing circuit breaker to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: A miniature reclosing circuit breaker includes a mounting base, on the outer wall of which a current sensor is provided, wherein two sets of current sensors are provided and are respectively located on the outer wall of the mounting base. A WiFi controller is installed on the outer wall of the mounting base, and a control panel is embedded in the outer wall of the WiFi controller. A small electromagnetic push-pull rod is installed on the inner wall of the mounting base.

[0006] As a preferred embodiment of this utility model, a gear set is installed on the inner wall of the mounting base, and a stationary contact is installed on one side of the gear set and on the inner wall of the mounting base.

[0007] As a preferred embodiment of this utility model, a motor is installed on one side of the stationary contact and on the inner wall of the mounting base, and a top cover is installed on the outer wall of the mounting base.

[0008] As a preferred embodiment of this utility model, a movable contact mechanism is rotatably connected to the inner wall of the mounting base, wherein the movable contact mechanism is located on one side of the gear set, and an arc track is provided on the inner wall of the mounting base.

[0009] As a preferred embodiment of this utility model, the drive shaft of the motor is threadedly connected to the outer wall of the gear set, and an input terminal interface is embedded in the side wall of the mounting base.

[0010] As a preferred embodiment of this utility model, an output interface is embedded in the side wall of the mounting base, the input interface and the output interface are respectively located on opposite side walls of the mounting base, and a conductive sheet is provided on the inner wall of the mounting base.

[0011] As a preferred embodiment of this utility model, the current sensor is located on one side of the output interface, and the control panel is electrically connected to the WiFi controller, the small electromagnetic push-pull rod, the motor and the current sensor via wires.

[0012] As a preferred embodiment of this utility model, the output end of the WiFi controller is connected to a gear set, wherein the small electromagnetic push-pull rod is located on one side of the moving contact mechanism.

[0013] The above technical solution connects the input and output interfaces to the circuit. When the switch is turned on, the motor drive shaft drives the gear set to rotate, which in turn drives the moving contact mechanism to move, so as to facilitate the opening and closing of the control device. When the device is turned on, there will be current in the line. When the current passes through the output interface, the current sensor will generate current data. At the same time, the current sensor generates an electrical signal that is transmitted to the control panel through the wire.

[0014] Compared with the prior art, the beneficial effects of this utility model are: 1. In this utility model, by connecting the input and output interfaces to the circuit, when the switch is turned on, the motor's drive shaft drives the gear set to rotate, which in turn drives the moving contact mechanism to move, facilitating the opening and closing of the control device. When the device is turned on, current flows through the circuit. When the current passes through the output interface, the current sensor generates current data, and the current sensor generates an electrical signal that is transmitted to the control panel via wires. When the motor starts, the current sensor on the output interface side does not generate a current signal, meaning that the set parameters are reached. In this case, the control panel controls the small electromagnetic push-pull rod to rotate, causing one end of the small electromagnetic push-pull rod to push the moving contact mechanism to contact the stationary contact. This ensures that the reclosing circuit breaker has a backup opening mechanism after the original opening structure fails, guaranteeing the normal operation of the device. This helps to solve the limitations of using gear transmission and mechanical linkage for position detection. When the mechanical mechanism malfunctions during the closing process, the detection mechanism cannot accurately determine the closing position, directly affecting the judgment of the actual opening and closing status of the reclosing circuit breaker.

However, the utility model can be implemented in many different forms and is not limited to the embodiments described herein. On the contrary, the purpose of providing these embodiments is to make the disclosure of the utility model more thorough and complete.

[0019] For examples, please refer to Figure 1-4 This utility model provides a technical solution: A miniature reclosing circuit breaker includes a mounting base 1, and a current sensor 2 is provided on the outer wall of the mounting base 1, wherein two sets of current sensors 2 are provided and are respectively located on the outer wall of the mounting base 1. A WiFi controller 3 is installed on the outer wall of the mounting base 1. A control panel 4 is embedded in the outer wall of the WiFi controller 3. A small electromagnetic push-pull rod 5 is installed on the inner wall of the mounting base 1.

[0020] In this embodiment, a gear set 6 is installed on the inner wall of the mounting base 1, a stationary contact 7 is installed on one side of the gear set 6 and on the inner wall of the mounting base 1, a motor 8 is installed on one side of the stationary contact 7 and on the inner wall of the mounting base 1, a top cover 9 is installed on the outer wall of the mounting base 1, a moving contact mechanism 10 is rotatably connected to the inner wall of the mounting base 1, wherein the moving contact mechanism 10 is located on one side of the gear set 6, and an arc track 11 is provided on the inner wall of the mounting base 1.

[0021] In this embodiment, the drive shaft of the motor 8 is threadedly connected to the outer wall of the gear set 6. An input terminal interface 12 is embedded in the side wall of the mounting base 1, and an output terminal interface 13 is embedded in the side wall of the mounting base 1. The input terminal interface 12 and the output terminal interface 13 are respectively located on opposite side walls of the mounting base 1. A conductive sheet 14 is provided on the inner wall of the mounting base 1.

[0022] The current sensor 2 is located on one side of the output interface 13. The control panel 4 is electrically connected to the WiFi controller 3, the small electromagnetic push-pull rod 5, and the current sensor 2 via wires, which enables the device to be powered on, thereby enabling the control panel 4 to control the WiFi controller 3, the small electromagnetic push-pull rod 5, the motor 8, and the current sensor 2 to operate.

[0023] The output of the WiFi controller 3 is connected to a gear set 6, and the small electromagnetic push-pull rod 5 is located on one side of the moving contact mechanism 10.

[0024] Based on the above structural features and connection relationships, the input interface 12 and the output interface 13 are connected to the circuit. When the switch is turned on, the drive shaft of the motor 8 will drive the gear set 6 to rotate, which will cause the gear set 6 to drive the moving contact mechanism 10 to move, so as to facilitate the opening and closing of the control device. When the device is turned on, there will be current in the line. When the current passes through the output interface 13, it will cause the current sensor 2 to generate current data. At the same time, the current sensor 2 generates an electrical signal that is conducted to the control panel 4 through the wire. The working process of this utility model is as follows: When the small reclosing circuit breaker designed in this scheme is working or running, the control panel 4 is electrically connected to the WiFi controller 3, the small electromagnetic push-pull rod 5, the motor 8 and the current sensor 2 through wires, so that the device is powered on, and the control panel 4 controls the WiFi controller 3, the small electromagnetic push-pull rod 5 and the current sensor 2 to operate. By connecting the input interface 12 and the output interface 13 to the circuit, when the switch is turned on, the drive shaft of the motor 8 drives the gear set 6 to rotate, which in turn drives the moving contact mechanism 10 to move, thus facilitating the opening and closing of the control device. When the device is turned on, current flows through the circuit. When this current passes through the output interface 13, it causes the current sensor 2 to generate current data. Simultaneously, the electrical signal generated by the current sensor 2 is transmitted to the control panel 4 via wires. When the motor 8 starts, the current sensor 2 on the output interface 13 side does not generate a current signal, meaning that... When the set parameters are reached, the control panel 4 will control the small electromagnetic push-pull rod 5 to operate, which will cause one end of the small electromagnetic push-pull rod 5 to push the moving contact mechanism 10 to contact the stationary contact 7. This will ensure that the reclosing circuit breaker has a backup opening mechanism after the original opening structure fails, so as to ensure the normal operation of the device. This helps to solve the problem that the position detection method using gear transmission and mechanical linkage has certain limitations. When the mechanical mechanism fails or malfunctions during the closing process, the detection mechanism will find it difficult to accurately determine the closing position, which will directly affect the judgment of the actual opening and closing status of the reclosing circuit breaker.
