[0021] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.
[0022] Example 1
[0023] An intermittent aging test machine for capacitors, see Figure 1-Figure 4, including a testing machine 1, a placement plate 2, a first docking plate 3 and a display screen 4. A plurality of first docking plates 3 are arranged on the testing machine 1 by means of bolt connection. The first docking plate 3 is fixedly connected to the placement plate 2. A display screen 4 for displaying detection data is embedded on the front side of the testing machine 1. It also includes a connecting plate 5 and an isolation plate 6. Two connecting plates 5 are fixedly connected to the testing machine 1. The two connecting plates 5 are rotatably arranged with an isolation plate 6 together. The isolation plate 6 is rotated downward to isolate the capacitor. It also includes a foot pad 11. Two foot pads 11 are arranged at the bottom of the testing machine 1 by means of bolt connection. The foot pad 11 prevents the testing machine 1 from directly contacting the ground, causing the testing machine 1 to be damp, thereby affecting the normal operation of the testing machine 1. It also includes a pull rod 12. The pull rod 12 is arranged on the isolation plate 6. The pull rod 12 increases the contact area between the hand and the isolation plate 6, thereby facilitating the rotation of the isolation plate 6.
[0024] When the capacitor needs to be tested, the staff moves the test machine 1 to the appropriate position, the staff holds the pull rod 12 and turns the isolation plate 6 upward to open the placement plate 2, and then the capacitor is inserted into the first docking plate 3 through the placement plate 2. Subsequently, the staff turns the isolation plate 6 downward to close the placement plate 2, so that the isolation plate 6 isolates the capacitor to prevent the capacitor from being damaged by excessive temperature during testing. Then, the staff turns on the test machine 1 to test the capacitor, watches the display screen 4 and records the data, and finally determines whether the capacitor is aged based on the recorded data. When moving the test machine 1 to the appropriate position, the foot pad 11 prevents the test machine 1 from directly contacting the ground to make the test machine 1 damp.

The fixing frame 8 is provided with an air outlet pipe 9, and the air outlet pipe 9 is connected with the exhaust fan 7. The exhaust fan 7 is operated to extract the gas in the test machine 1. It also includes a second docking plate 10. The left and right ends of the placement plate 2 are fixedly connected with the second docking plates 10.
[0027] When testing the capacitor, the staff turns on the vacuum pump 7, which extracts the gas in the test machine 1 and discharges it through the outlet pipe 9, thereby achieving the purpose of quickly clearing the internal temperature and improving the efficiency of the test.
