[0035] To make the objectives, technical solutions, and advantages of the embodiments of the present invention clearer, the embodiments of the present invention will be further described in detail below with reference to the accompanying drawings. Here, the illustrative embodiments of the present invention and their descriptions are used to explain the present invention, but are not intended to limit the present invention.

[0036] To facilitate a clear description of the technical solutions of the embodiments of the present invention, the terms "first" and "second" are used in the embodiments of the present invention to distinguish the same or similar items with essentially the same function and effect. Those skilled in the art will understand that the terms "first" and "second" do not limit the quantity or execution order.

[0037] Traditional circuit breaker testing includes DC insulation resistance testing and AC withstand voltage testing. Both tests require separate devices, each equipped with an output port, and each device has a size of 0.036m². 3 The independent device is bulky, which is not user-friendly and results in low operating efficiency.

[0038] This invention relates to an integrated, multi-functional intelligent cloud circuit breaker sequential control testing instrument. It features a structural innovation that enables automatic switching between DC and AC voltages, allowing the same device to perform two tests sequentially.

[0039] Figure 1 This is a schematic diagram of a high-voltage conversion device for circuit breaker sequential control detection in an embodiment of the present invention, as shown below. Figure 1 As shown, the device includes a plug fixing module, a control module, a switching module, and a step-up transformer module.

[0040] The plug fixing module is used to fix the plug of the high-voltage line of the circuit breaker.

[0041] The control module is connected to the switching module and the step-up transformer module. The control module is used to: receive control commands and transmit the control commands to the switching module and the step-up transformer module.

[0042] The switching module includes a first end and a second end. The switching module is used to control the connection of the first end or the second end to the plug fixing module according to the control command transmitted by the control module. The first end includes a DC power supply and the second end includes an AC power supply.

[0043] The step-up transformer module is connected to the switching module. The step-up transformer module is used to step up and transform the voltage of the DC power supply or AC power supply according to the control instructions transmitted by the control module.

[0044] Figure 2 This is a specific example diagram of a high-voltage conversion device for circuit breaker sequential control detection in an embodiment of the present invention. Figure 2 The specific structural features of the plug fixing module and the control module are shown. For example... Figure 2 As shown, the plug fixing module may include a high-voltage plug cover, a high-voltage line fixing seal, and a high-voltage line socket. The high-voltage line socket is used to fix the plug of the circuit breaker's high-voltage line, and the high-voltage line fixing seal is used to seal and fix the circuit breaker's high-voltage line. The high-voltage plug cover is used to cover the plug of the circuit breaker's high-voltage line, ensuring the smoothness of the interface of the intelligent cloud circuit breaker sequential control detection instrument and promoting electrical safety.

[0045] In one embodiment, reference is made to Figure 2 The high-voltage line fixing seal and the high-voltage line socket adopt a retractable honeycomb structure.

[0046] In this embodiment, the high-voltage line fixing seal serves a sealing and fixing function. Its internal expandable honeycomb structure secures the high-voltage line, achieving a stable line connection. The high-voltage line socket functions to fix the high-voltage line plug. It primarily uses a honeycomb structure of a special material on its inner side to fit the high-voltage plug, providing high-voltage insulation and a tight connection between the plug and the high-voltage line.

[0047] Continue to refer to Figure 2 The control module may include a control panel, a panel sealing ring, and a panel socket. The control panel receives control commands and integrates connectors for various test items and data transmission connection points. The panel sealing ring seals the control panel, primarily sealing the gap between the panel opening and the socket. The panel socket secures the control panel to a designated location. For example, the panel socket is fixed to a conversion base connected to a chassis, allowing the high-voltage conversion device to stand stably upright.

[0048] In one embodiment, the switching module is specifically used to: control the first end to connect to the plug fixing module via a first stepper motor, or control the second end to connect to the plug fixing module via a second stepper motor, according to the control command transmitted by the control module; wherein the first stepper motor and the second stepper motor are connected to the control module.

[0049] In this embodiment of the invention, the switching module adopts a retractable honeycomb structure. The complementarity of the honeycomb structure enables the switching block of the test module to play a key role in both AC and DC modes of the high-voltage conversion device, and the connection is tight after switching. The honeycomb structure is made of a special material, which provides safe insulation in a confined space, improving the safety factor and ensuring the safety of the high-voltage testing process.

[0050] In a preferred embodiment, the high-voltage conversion device is in the shape of a three-dimensional L, wherein the first stepper motor moves in the vertical direction and the second stepper motor moves in the horizontal direction.

[0051] Figure 3 This is another specific example diagram of a high-voltage conversion device for circuit breaker sequential control detection in an embodiment of the present invention, as shown below. Figure 3 As shown, the system includes a high-voltage line fixing module (including a plug fixing module and a control module), a honeycomb structure, a stepper motor (1), a stepper motor (2), and a high-voltage line. Stepper motor (2) moves vertically, carrying the DC high-voltage line and connecting to the contact point inside the elliptical dotted coil. Stepper motor (1) is located below the right-hand honeycomb structure, driving the honeycomb structure to move, and also connecting to the contact point inside the elliptical dotted coil. The two stepper motors cannot be connected to the high-voltage contact point simultaneously; one needs to be moved away before the other enters the site for connection. The high-voltage line is an AC high-voltage line, connected to an AC step-up transformer. When the step-up transformer is working, the stepper motor drives the honeycomb structure to move horizontally.

[0052] In this example, the high-voltage conversion device is shaped like a three-dimensional L. During implementation, one stepper motor moves vertically and another moves horizontally. The vertically moving stepper motor moves upwards, creating space for the horizontally moving stepper motor, allowing the AC power supply and the high-voltage plug to connect. Conversely, the horizontally moving stepper motor moves backwards, causing the DC power supply to move downwards and connect to the high-voltage plug.

[0053] In one embodiment, the step-up transformer module includes a step-up transformer and a silicone-insulated high-voltage wire, wherein the step-up transformer is connected to a DC power supply and an AC power supply via the silicone-insulated high-voltage wire.

[0054] Figure 4 This is another specific example diagram of a high-voltage conversion device for circuit breaker sequential control detection in an embodiment of the present invention, as shown below. Figure 4 As shown, a step-up transformer, high-voltage lines, and a honeycomb structure are illustrated. The step-up transformer functions as a DC / AC voltage converter. The rubber-insulated high-voltage lines serve as connectors, and the high-voltage lines, protected by silicone sheath insulation, are connected to the stepper motor and the step-up transformer. Figure 4 medium and high voltage lines and Figure 3 The medium and high voltage lines are connected together because the stepper motor is moving. This high voltage line is flexible and has external insulation protection. It moves with the stepper motor within a certain distance. The straight-line length of the high voltage line has a margin to ensure that it can move safely.

[0055] In one embodiment, the volume of the device is between 0.01 cubic meters and 0.02 cubic meters.

[0056] For example, the volume of this high-voltage conversion device is 0.014 m³. 3 Compared to traditional devices, the traditional rotating threaded structure, while ensuring insulation, suffers from a large size due to length requirements (according to standards, a certain length is required to meet insulation safety requirements). This invention utilizes a miniaturized high-voltage conversion device to complete the testing tasks that previously required two independent devices, reducing the overall size by 80%. This invention cleverly employs a scalable "honeycomb" structure to achieve automatic switching between DC and AC high voltage. The special material of the "honeycomb" structure ensures sufficient and safe electrical insulation gaps within the confined space. The digital intelligent operating program enables online collection of test data, remote data transmission, and remote control—multifunctional testing capabilities that lay the foundation for real-time analysis of high and low voltage test results and for operators to issue timely and correct operating instructions.

[0057] In one embodiment, the control module includes a network module; specifically, the control module is used to: communicate with the user terminal through the network module and receive control commands sent by the user terminal.

[0058] For example, a stepper motor carrying both AC and DC high-voltage lines is controlled by control commands sent from a user terminal, enabling automatic switching and remote control of AC and DC voltages.

[0059] For example, intelligent operating procedures control step-up transformers to achieve intelligent operation, remote control, data collection, and transmission functions.

[0060] In summary, the high-voltage conversion device for circuit breaker sequential control testing in this embodiment of the invention is connected to digital programs on terminals such as computers and mobile phones, realizing functions such as port sharing, DC / AC high-voltage conversion, online collection of test data, remote data transmission, and remote intelligent control. It enables real-time analysis of test results and remote operation. The high-voltage conversion device uses new materials and a stretchable honeycomb structure to achieve safe insulation in a confined space. One high-voltage conversion device has the testing functions of two existing independent devices, and its compact size saves 80% of space. The high-voltage conversion device is mainly used to switch between DC voltage and AC high voltage, and to perform DC insulation resistance testing and AC withstand voltage testing of the circuit breaker.

[0061] In this embodiment of the invention, high voltage refers to a voltage exceeding a set threshold, which is set according to the actual situation.

Finally, the experimental data is automatically uploaded to the cloud, and an experimental report is automatically generated and downloaded and printed from the cloud.
