[0020] like Figure 1-3 As shown, a capacitor circuit board aging device includes a test frame 1, multiple placement seats 5, multiple wiring seats 6 and a heating component.

[0021] Specifically, the test frame 1 is composed of multiple insulating support plates 2 and four support columns 3. The test frame 1 is connected to a distribution box 4. The upper surface of each insulating support plate 2 is evenly provided with multiple placement seats 5. Each insulating support plate 2 is connected to multiple wiring seats 6. There are corresponding multiple wiring seats 6 on both sides of each placement seat 5. Each placement seat 5 is evenly provided with four limiting rods. A capacitor circuit board 7 is placed on each placement seat 5. The placement seat 5 can lift the capacitor circuit board 7, increase the contact area between the capacitor circuit board 7 and the hot air, and ensure the test effect; each limiting rod passes through the fixing hole on the corresponding capacitor circuit board 7, and the heating assembly is installed on the test frame 1 for testing the heat resistance of the capacitor circuit board.

[0022] Specifically, the heating component includes a bracket 8, a hollow support plate 9, a heating wire 10 and a fan 11. A magnetic seat 12 is installed on the two support columns 3 at the rear end, and each magnetic seat 12 is tightly attached to a corresponding magnetic part 13. The two magnetic parts 13 are connected to the bracket 8. A plurality of hollow support plates 9 are connected to the bracket 8. A heating wire 10 is installed in each hollow support plate 9. A plurality of fans 11 are also installed on the bracket 8, and each fan 11 is close to the corresponding hollow support plate 9; a plurality of ventilation holes 14 are evenly opened on the hollow support plate 9, and each fan 11 is close to the corresponding ventilation hole 14. The hot air generated by the heating wire 10 can circulate through the plurality of ventilation holes 14. Under the action of the plurality of fans 11, the hot air generated by the heating wire 10 is brought to each capacitor circuit board 7.

[0023] Specifically, each capacitor circuit board 7 is electrically connected to the corresponding multiple terminal blocks 6, and each capacitor circuit board 7 is connected in parallel with each other; each insulating support plate 2 is at an angle of 30° to the ground, which makes it convenient to observe the aging test of the capacitor circuit board 7; a power supply is installed in the distribution box 4, and the power supply is electrically connected to each capacitor circuit board 7, and the power supply supplies power to each capacitor circuit board 7. A relay is electrically connected to the parallel circuit where each capacitor circuit board 7 is located, and a relay switch 15 is installed on the front end surface of each insulating support plate 2. The switch 15 can control the switch of a single circuit without affecting other capacitor circuit boards 7 in the parallel circuit. Four sliding wheels are installed at the bottom of the bracket 8, and the bracket 8 can be conveniently moved by the four sliding wheels.

[0024] Working principle: First, place the capacitor circuit board 7 to be tested on the placement seat 5 so that the limit rod on the placement seat 5 can pass through the corresponding fixing hole of the capacitor circuit board 7. This can ensure the stability of the capacitor circuit board 7 during testing. Then connect the capacitor circuit board 7 and the corresponding terminal block 6 through wires, turn on the switch 15 and the power supply, and test the voltage resistance of the capacitor circuit board 7 to observe whether there are any abnormal phenomena such as leakage, overheating or noise;

[0025] Then, a heat resistance test is performed. The bracket 8 is moved and brought close to the rear end of the test frame 1 until the magnetic part 13 on the bracket 8 is in close contact with the magnetic base 12 on the test frame 1. Then, multiple heating wires 10 and multiple fans 11 are started. Under the action of multiple fans 11, the hot air generated by the heating wires 10 is brought to multiple insulating support plates 2. The hot air wraps around the capacitor circuit board 7, simulating the situation of the capacitor circuit board 7 in a heating electrical device. In this way, the aging test of the capacitor circuit board 7 is sufficiently comprehensive.
