[0026] like Figure 1 As shown, this embodiment of the present invention provides a circuit breaker safety performance testing device, including a main unit 1. The main unit 1 internally houses a temperature acquisition module, a current acquisition module, and a leakage current acquisition module. One end of the main unit 1 is internally equipped with a temperature acquisition connector 101, a current acquisition connector 102, and a leakage current acquisition connector 103. Each of these connectors has an interface 2. The working status of the main unit 1 and its acquisition modules is checked to ensure the device is in normal working order. The temperature sensor, current sensor, and leakage current sensor are connected to their respective acquisition connectors, ensuring a secure and reliable connection. The main unit 1 is then turned on and enters standby mode, ready for data acquisition. When the circuit breaker is in operation, the temperature sensor, current sensor, and leakage current sensor collect the circuit breaker's temperature and current in real time. The collected data, including leakage current data, is transmitted to the acquisition module inside the device host 1 through the corresponding acquisition connector. The acquisition module performs preliminary processing on the received data, such as filtering and amplification, to improve the accuracy and reliability of the data. The processor inside the device host 1 further analyzes and processes the collected data, extracts key safety performance parameters, and judges and evaluates the extracted parameters according to preset safety thresholds to determine whether the safety performance of the circuit breaker meets the requirements. If abnormal data or parameters are found to exceed the safety threshold, the device host 1 will issue an alarm signal to prompt the operator to handle the situation. The device host 1 generates a detailed test report based on the collected data, analysis results, and alarm information. The test report can be stored in the internal memory of the device host 1 or uploaded to a remote server or data center via a network interface for backup and further analysis.

[0027] In this embodiment, as shown in Figures 1 to 3 Dustproof assembly is used to prevent dust from entering the inside of the docking port 2, and the dustproof assembly is connected with the docking port 2. The dustproof assembly includes two baffle plates 3 which are respectively rotatably connected at the top and bottom of the inner cavity of the docking port 2. The two sides of the baffle plate 3 are fixedly connected with guide blocks 301, and the inside of the guide block 301 is provided with a guide hole. The top and bottom of the two sides of the inner cavity of the docking port 2 are provided with arc-shaped guide cavities 201, and the inside of the guide cavity 201 is fixedly connected with an arc-shaped guide column 202 which has the same shape. The guide block 301 is slidingly connected outside the arc-shaped guide column 202. The outside of the arc-shaped guide column 202 is sleeved with a reset spring 203. One end of the reset spring 203 is fixedly connected with one end of the guide cavity 201, and the other end of the reset spring 203 is fixedly connected with the guide block 301. When there is no cable connector inserted into the docking port 2, the two baffle plates 3 are tightly attached to the top and bottom of the inner cavity of the docking port 2 under the action of the reset spring 203, forming a dustproof barrier to effectively prevent dust and other impurities from entering the inside of the docking port 2. When it is necessary to insert the cable connector for data collection, the operator aligns the cable connector with the docking port 2 and gently pushes it in. With the insertion of the cable connector, its front end will contact the baffle plate 3 and push it to move outward. At this time, the guide block 301 slides along the arc-shaped guide cavity 201 under the guidance of the arc-shaped guide column 202, while the reset spring 203 is compressed. When the cable connector is completely inserted into the docking port 2, the baffle plate 3 is tightly attached around the cable connector under the elastic force of the reset spring 203, forming a tight dustproof seal. At the same time, due to the clamping action of the baffle plate 3, the cable connector is stably fixed in the docking port 2, ensuring the stability and accuracy of data collection. When it is necessary to pull out the cable connector, the operator gently pulls the cable. With the pulling out of the cable connector, the baffle plate 3 quickly returns to the initial state under the action of the reset spring 203, forming a dustproof barrier again. Through the design of the two baffle plates 3 and the reset spring 203, the dustproof assembly can automatically close when the docking port 2 is not in use, effectively preventing dust and other impurities from entering the inside of the equipment, ensuring the cleanliness and service life of the equipment. The baffle plate 3 can provide a certain clamping force to the cable connector under the action of the reset spring 203, ensuring the tight connection between the cable connector and the docking port 2, reducing the signal transmission problems caused by loose connection or poor contact. The structure of the dustproof assembly is relatively simple, composed of baffle plates 3, guide blocks 301, arc-shaped guide columns 202 and reset springs 203, easy to manufacture, install and maintain. At the same time, due to the relatively simple connection and cooperation between the components, the maintenance and maintenance of the equipment also become easier. The addition of the dustproof assembly not only improves the dustproof performance of the equipment, but also indirectly improves the safety and reliability of the equipment. By preventing dust and other impurities from entering the inside of the equipment, the safety hazards caused by short circuit and other faults are reduced.

[0028] In this embodiment, as Figures 1 to 3 As shown, the top of the bottom baffle 3 has two first grooves 302 and one second groove 304, and the bottom of the top baffle 3 also has one first groove 302 and two second grooves 304. A guide roller 303 is rotatably connected inside each second groove 304. The surface of the guide roller 303 has a spiral groove, and the outside of the guide roller 303 is located inside the first groove 302. When the cable connector begins to be inserted into the interface 2, its front end first contacts the guide roller 303. Because the surface of the guide roller 303 has a spiral groove, it can guide the cable connector smoothly into the interface 2 and reduce the resistance caused by friction. Simultaneously, as the cable connector is inserted, the guide roller 303 rotates within the second groove 304, further enhancing the guiding effect of the cable connector. As the cable connector continues to be inserted, it pushes the baffle 3 outward. At this time, the guide block 301 slides under the guidance of the arc-shaped guide post 202 and compresses the return spring 203. Once the cable connector is fully inserted, the baffle 3, under the action of the return spring 203, tightly adheres to the area around the cable connector, forming a dustproof seal. Simultaneously, the design of the first groove 302 and the second groove 304 provides sufficient space for the guide roller 303, ensuring it does not interfere with the clamping action of the baffle 3. When it is necessary to remove the cable connector, the operator gently pulls the cable. At this time, the spiral groove design of the guide roller 303 helps the cable connector smoothly exit the interface 2, reducing wear and resistance caused by friction. As the cable connector is pulled out, the baffle 3 quickly returns to its initial state under the action of the return spring 203. The guide roller 303 and its spiral groove design make the cable connector smoother when inserted and pulled out of the interface 2, reducing the resistance and wear caused by friction and extending the service life of the equipment. The rotation of the guide roller 303 not only helps the cable connector to enter the interface 2 smoothly, but also corrects the insertion angle of the cable connector to a certain extent, ensuring its accurate docking with the interface 2. The design of the first groove 302 and the second groove 304 provides sufficient space for the guide roller 303, while not affecting the clamping function of the baffle 3. In this way, after the cable connector is pulled out, the baffle 3 can quickly return to its initial state, forming a tight dust barrier. Since the guide roller 303 is rotatable and located in the second groove 304, even if dust or impurities accumulate during use, its performance can be restored through a simple cleaning operation.

[0029] The working principle of this utility model is as follows: When no cable connector is inserted into the interface 2, the two baffles 3, under the action of the return spring 203, are tightly fitted against the top and bottom of the inner cavity of the interface 2, forming a dust barrier to effectively prevent dust and other impurities from entering the interface 2. When a cable connector needs to be inserted for data acquisition, the operator aligns the cable connector with the interface 2 and gently pushes it in. As the cable connector is inserted, its front end contacts the baffle 3 and pushes it outward. At this time, the guide block 301 slides along the arc-shaped guide cavity 201 under the guidance of the arc-shaped guide post 202, while compressing the return spring 203. When the cable connector is fully inserted into the interface 2, the baffle 3, under the elastic force of the return spring 203, tightly fits around the cable connector, forming a tight dust seal. At the same time, due to the clamping effect of the baffle 3, the cable connector is firmly fixed inside the interface 2, ensuring the stability and accuracy of data acquisition. When it is necessary to remove the cable connector, the operator gently pulls the cable. As the cable connector is pulled out, baffle 3 quickly returns to its initial state under the action of return spring 203, forming a dust barrier again. Through the design of two baffles 3 and return spring 203, the dustproof component can automatically close when the interface 2 is not in use, effectively preventing dust and other impurities from entering the equipment, ensuring the cleanliness and service life of the equipment. Under the action of return spring 203, baffle 3 provides a certain clamping force to the cable connector, ensuring a tight connection between the cable connector and interface 2, reducing signal transmission problems caused by loose connections or poor contact. When the cable connector begins to be inserted into interface 2, its front end first contacts guide roller 303. Because the guide roller 303 has spiral grooves on its surface, it guides the cable connector smoothly into interface 2 and reduces resistance caused by friction. Simultaneously, as the cable connector is inserted, guide roller 303 rotates within groove 304, further enhancing the guiding effect of the cable connector. As the cable connector continues to be inserted, it pushes baffle 3 outward. At this point, the guide block 301 slides under the guidance of the arc-shaped guide post 202, compressing the return spring 203. Once the cable connector is fully inserted, the baffle 3, under the action of the return spring 203, tightly adheres to the area around the cable connector, forming a dustproof seal. Simultaneously, the design of the first groove 302 and the second groove 304 provides sufficient space for the guide roller 303, ensuring it does not interfere with the clamping action of the baffle 3. When the cable connector needs to be removed, the operator gently pulls the cable. The spiral groove design of the guide roller 303 helps the cable connector smoothly exit the interface 2, reducing wear and resistance caused by friction. As the cable connector is removed, the baffle 3 quickly returns to its initial state under the action of the return spring 203.
