Any changes or adjustments to their relative relationships, without substantially altering the technical content, should also be considered within the scope of the invention.

[0055] like Figure 1 and Figure 2 As shown, the present invention provides a remote emergency opening and closing device for a circuit breaker, comprising:

[0056] Fixed bracket assembly 10 is used to provide mechanical support and installation reference;

[0057] The electromagnetic drive module 20 is mounted on the fixed bracket assembly and is used to perform non-contact electromagnetic drive on the opening and closing operation mechanism on the circuit breaker cabinet door.

[0058] The power supply module 30 is mounted on the fixed bracket assembly and is used to provide operating voltage to the electromagnetic drive module.

[0059] The remote control module 40 communicates wirelessly with the electromagnetic drive module and is used for remote control of the electromagnetic drive module.

[0060] The output terminal of the power module 30 is connected to the electromagnetic drive module 20, and the remote control module 40 communicates wirelessly with the electromagnetic drive module 20.

[0061] In this embodiment of the invention, the electromagnetic drive module and the power supply module are installed on the circuit breaker cabinet door by a fixed bracket assembly. The electromagnetic drive module operates the open and close buttons on the circuit breaker cabinet door according to the control commands of the remote control module to achieve remote control. The power supply module provides the working voltage to the electromagnetic drive module to ensure the normal operation of the electromagnetic drive module.

[0062] This invention sends a remote control signal to the electromagnetic drive module via a remote control module. The electromagnetic drive module then sends control commands to the drive motor and electromagnetic coil based on the remote control signal. The drive motor operates and operates the trip button via an electromagnetic actuator, thus tripping the circuit breaker. This achieves remote tripping, ensuring operational safety and making the tripping operation smoother and more convenient, reducing the risk of tripping failure due to mechanical jamming or other problems.

[0063] See Figure 2 The fixed bracket assembly 10 includes:

[0064] A support frame 101 is provided with a slide rail 111, and a mounting slot 112 is provided on the slide rail 1411.

[0065] Electromagnetic chucks 102 are symmetrically distributed at the bottom of the support frame 101 and are used to establish a detachable magnetic connection with the circuit breaker cabinet door.

[0066] In this embodiment of the invention, an electromagnetic control module is mounted on the support frame. The support frame is installed on the relay cabinet door using an electromagnet chuck, without damaging the relay cabinet door. The module is easily installed and disassembled by using an electromagnet that is energized to adhere to the support frame.

[0067] See Figure 3 The electromagnetic drive module 20 provided by the present invention includes:

[0068] The slider base 201 is mounted on the slide rail 111 and can move along the slide rail 111;

[0069] The electromagnetic coil 202 is mounted on the sliding base 201 and is electrically connected to the power module 30;

[0070] The electromagnetic actuator 203 generates axial displacement in response to changes in the electromagnetic field of the excitation coil, which is used to trigger opening or closing operations.

[0071] The drive motor 204 is used to drive the sliding base 201 to move above the opening or closing button;

[0072] The drive controller 205 is used to receive control signals from the remote control module 40 and control the electromagnetic coil 202 and the drive motor 204.

[0073] The slider base provides support for the electromagnetic coil and electromagnetic actuator, which are mounted on the slider base. As the slider base moves along the slide rail, it drives the electromagnetic actuator to move. When an emergency trip is required, the electromagnetic actuator operates the trip button to complete the trip. The remote emergency tripping device for circuit breakers provided by this invention can also achieve remote closing operations. Specifically, when the circuit breaker is in the open state, a closing signal from the remote control module controls the drive motor to move the slider base to the closing button position, controlling the electromagnetic actuator to operate the closing button to close the circuit breaker. This invention achieves remote control of both tripping and closing, is convenient to operate, requires no manual operation, saves time, and improves operational efficiency.

[0074] In this embodiment of the invention, the remote control module 40 includes:

[0075] Remote controller 401 is used to generate control signals for opening, closing, and position adjustment commands.

[0076] The wireless communication module 402 is used to send control commands to the drive controller 205.

[0077] The wireless communication module can use short-range wireless control methods such as WIFI, Bluetooth, and LoRa antennas, or it can communicate via the Internet, 4G / 5G, etc.

[0078] See Figure 1 At least two sets of electromagnet chucks 102 are provided and symmetrically arranged on both sides of the support frame 101. The load-bearing capacity of each electromagnet chuck 102 is 50kg. The power module continuously supplies power to the electromagnet chucks, so that they are tightly attached to the circuit breaker cabinet door. When it is necessary to remove the electromagnet chucks, the power supply to the power module and the electromagnet chucks can be disconnected.

[0079] The electromagnet chuck 102 is connected to the support frame via an adjustable bracket 103. The adjustable bracket 103 is an adjustable metal bracket that fixes the electromagnetic drive module with bolts and has an insulating layer to insulate the electromagnetic drive module from the relay cabinet door.

[0080] To ensure the reliability of the remote emergency tripping device for the circuit breaker, a safety detection unit 206 is also included, which is used to detect the system installation status and the electromagnet attraction force to ensure safe and reliable operation.

[0081] In this embodiment of the invention, the power module 30 includes a DC power conversion unit 301 and a backup battery 302 to ensure continuous power supply in emergencies. The DC power conversion unit is connected to an external power supply to power the electromagnetic drive module. The backup battery prevents the electromagnet chuck from losing power when the external power supply is disconnected. The backup battery is a rechargeable battery; when the external power supply is normal, the backup battery can be charged to ensure reliable power supply to the electromagnet chuck.

[0082] The remote control module provided by this invention adopts bidirectional communication technology and can receive feedback signals of opening and closing status.

[0083] The remote control module controls the relay switching via wireless signal, which enables the power module to supply power to the electromagnetic drive module. The chuck electromagnet generates magnetic force to fix the system position, and the trip coil generates mechanical action to trigger the circuit breaker trip button.

[0084] This invention uses bolts to fix two 50kg suction cup electromagnets and a trip coil to a bracket. A power module supplies power to the suction cup electromagnets, making them firmly attached to the switch cabinet panel. A remote control device controls the trip relay, so that in an emergency, the trip coil is activated, pushing down the emergency trip button on the switch cabinet panel, thus achieving the function of remote tripping.

[0085] This invention enables remote and rapid operation, features a stable and non-deformable device structure, reduces safety risks for operators, ensures personnel safety, is easy to install and dismantle, and simultaneously improves the stability and reliability of power grid operation.

[0086] This invention enables remote and rapid tripping of the circuit breaker in the event of a control circuit disconnection, solving the problem of inconvenient operation of existing emergency tripping devices, optimizing the operation process, shortening the tripping time, improving the efficiency of power grid fault handling, reducing power outage time and scope, and reducing economic losses.

[0087] See Figure 4 This invention proposes a method for remote emergency opening and closing of a circuit breaker, comprising the following steps:

[0088] Step S1: Fix the system to the circuit breaker cabinet door using an electromagnet chuck;

[0089] Step S2: Send a trip command via the remote control module;

[0090] Step S3: The electromagnetic drive module receives the trip command and controls the electromagnetic coil to drive the electromagnetic actuator to operate the trip button.

[0091] Step S4: The remote control module sends a closing command;

[0092] In step S5, the electromagnetic drive module controls the slider bracket to move along the slide rail to the position of the closing button, and controls the electromagnetic coil to drive the electromagnetic actuator to operate the closing button.

[0093] Furthermore, although the operations of the method of the present invention are described in a specific order in the accompanying drawings, this does not require or imply that these operations must be performed in that specific order, or that all the operations shown must be performed to achieve the desired result. Additionally or alternatively, certain steps may be omitted, multiple steps may be combined into one step, and / or one step may be broken down into multiple steps.
