[0028] The present invention will be further described below with reference to the accompanying drawings.

[0029] Figure 1 FIG. 1 shows the structure of an electrical equipment performance testing device 100 according to an embodiment of the present invention. Figure 2 This is a schematic diagram of the system connection of the test system control device 3. Figure 1 and Figure 2 As shown, the electrical equipment performance test device 100 of the embodiment of the present invention includes a support frame 1, a power module assembly 2 and a test system control device 3. The power module assembly 2 is movably arranged on the top of the support frame 1 and is used to form an electrical connection with an external safety tester 4; the test system control device 3 is movably arranged above the power module assembly 2 and is used to connect to the electrical equipment 5 (combined with the power module assembly 2). Figure 5 and Figure 6 As shown) to form an electrical connection, the test system control device 3 is provided with an electrical safety test system 3a (combined with Figure 2 As shown), the test system control device 3 is configured to be able to move toward the power module assembly 2 under the drive of an external drive device to form an electrical connection with the power module assembly 2, so that the electrical equipment, the electrical safety test system 3a and the safety tester 4 are connected to form an electrical safety test circuit.

[0030] The electrical equipment performance test device 100 according to the embodiment of the present invention can be applied to the performance test of an air conditioner. Figure 5 and Figure 6 As shown, before the test begins, the tester connects the power module assembly 2 to the safety tester 4 and uses a wiring tool to connect the test system control device 3 to the air conditioner 5. The electrical equipment performance testing device 100 is turned on, and the test system control device 3, located above the power module assembly 2, moves toward the power module assembly 2. When the test system control device 3 reaches the power module assembly 2, the power module assembly 2 detects the position of the test system control device 3 and establishes an electrical connection with it. Because the test system control device 3 includes an electrical safety test system 3a, the electrically connected power module assembly 2 and test system control device 3 connect the electrical equipment, the electrical safety test system 3a, and the safety tester 4 to form an electrical safety test circuit, thereby initiating the electrical safety test.

[0031] Through the above-mentioned configuration, the electrical equipment performance test device 100 according to the embodiment of the present invention has the following advantages: 1) During the entire electrical safety test process, the tester only needs to connect the wiring before the test begins, and no manual operation is required during the test process, thereby achieving automatic testing of the electrical safety of the electrical equipment. This not only directly reduces the investment in labor costs, but also effectively ensures the personal safety of the tester in a high-voltage test environment. 2) During the test process, the electrical equipment performance test device 100 according to the embodiment of the present invention is configured to be movable. In this way, during the test process, the test system control device 3 and the power module assembly 2 can be in a synchronized moving state. Through this configuration, the electrical equipment performance test device 100 according to the embodiment of the present invention can be better adapted to existing dynamic production lines, thereby enabling the electrical equipment 5 (such as an air conditioner), the test system control device 3, and the power module assembly 2 to be in a mobile testing state, thereby effectively saving test time and improving test efficiency.

[0032] It should be understood that, in combination with the above description, the moving directions of the movably arranged power module assembly 2 and the movably arranged test system control device 3 should be in the same direction to ensure that the two can be in continuous contact, so as to achieve synchronous movement of the two under continuous electrical connection.

[0033] exist Figure 2 In the preferred embodiment shown, the test system control device 3 may also be provided with an operating test system 3b, combined with Figure 1 As shown, the electrical equipment performance testing device 100 may also include a control device 6 disposed on the test system control device 3. The control device 6 is electrically connected to the electrical safety test system 3a and the operational test system 3b, respectively. The control device 6 may be configured to, after the electrical safety test circuit is disconnected, switch the test circuit to connect the electrical equipment 5 to the operational test system 3b, thereby forming a loop for the operational test system 3b. According to the present invention, the electrical equipment performance testing device 100 of this embodiment further includes an operational test function for the electrical equipment. In conjunction with the above description, after the electrical equipment 5 (e.g., an air conditioner), the test system control device 3, and the power module assembly 2 have been moving and tested for a period of time, it can be understood that the electrical safety test has concluded. At this point, the power module assembly 2 is disconnected from the test system control device 3, and the control device 6 switches the entire circuit so that the electrical equipment is directly connected to the operational test system 3b, thereby forming a loop for the operational test system 3b. Specifically, the switching method may be to switch the entire test circuit to the voltage and current values required for the operational test to implement the operational test. After the operational test is completed, the entire system is shut down, and the tester disconnects the wiring fixture from the electrical equipment, concluding the entire test process.

[0034] Through the above-described configuration, the electrical equipment performance test apparatus 100 according to the embodiment of the present invention integrates electrical safety testing and operational testing. Testers only need to assist in connecting test fixtures such as the grounding fixture and the grounding clamp to the electrical equipment 5 before the entire test to establish an electrical connection between the electrical equipment 5 and the test system control device 3. By setting an electrical safety test position and an operational test position, the electrical equipment performance test apparatus 100 according to the embodiment of the present invention enables the energized module assembly 2 and the test system control device 3 to be connected and disconnected at the corresponding positions, and the control device 6 to be switched to the operational test position. The entire process requires no human intervention, thereby not only enabling the electrical equipment to sequentially pass the electrical safety test and operational test, but also further ensuring the personal safety of the testers.

[0035] In a preferred embodiment, the control device 6 can also be configured to switch to the operating test circuit before starting the safety tester to test whether the connection terminals of the electrical device 5 are in good contact. This configuration can further ensure the safety and accuracy of the test.

[0036] exist Figure 3 In the preferred embodiment shown, the power module assembly 2 may include a mounting plate 21, an electrical connection assembly 22, and a sensing device 23.

The test system control device 3 may be configured to contact the sensing device 23, and the sensing device 23 may be configured to control the electrical connection assembly 22 to electrically connect to the test system control device 3 after contact with the test system control device 3. With this configuration, in this embodiment, the position of the test system control device 3 is determined by contact between the test system control device 3 and the sensing device 23. Thus, after the sensing device 23 is accurately positioned, the electrical connection assembly 22 is controlled to electrically connect the electrical connection assembly 22 to the test system control device 3, effectively ensuring the accuracy of the connection between the two.

[0037] exist Figure 4 In the preferred embodiment shown, the electrical connection assembly 22 may include a limiting component 221 and a solenoid valve 222 provided on the mounting plate 21. A probe 223 is provided in the limiting component 221 for sliding in the vertical direction. The probe 223 is connected to the solenoid valve 222 via a spring member 224. The solenoid valve 222 is electrically connected to the sensing device 23 so as to control the on and off of the solenoid valve 222 via the sensing device 23 to release and retract the probe 223. Through this arrangement, the probe 223 can be quickly docked and retracted through the cooperation of the spring member 224 and the solenoid valve 222, thereby further improving the connection speed and effectively improving the test efficiency.

It should be noted that the speed and direction of the guide rail 11 driving the power module assembly 2 to move in the horizontal direction under the drive of the driving device should be the same as the moving speed and direction of the test system control device 3 to achieve synchronous movement. At the same time, the guide rail 11 should have a preset moving stroke, which can be understood as an electrical safety test area that enables the test system control device 3 to continuously dock with the electrical connection component 22. After the guide rail 11 moves, it can be driven by the driving device again to move the power module assembly 2 to the initial position, waiting for the next docking test.
