[0001] The present invention relates to the field of measurement application technology, and in particular to a high-precision AC impedance testing device and a control method. Background Art

[0002] The high-precision AC impedance tester is a comprehensive measuring instrument used to measure and analyze the AC impedance of the rotor windings of generators and phase-converting phase converters. Through a specially designed measuring circuit, it can automatically measure the AC impedance, power, frequency and other parameters of the rotor windings. In the calibration, verification and testing of AC impedance testers, the detection of the transition process (including transition resistance and transition time) measurement function is the most important test item.

[0003] Since the calibration system of the tester used in the test is different from the actual working condition of the motor rotor winding, the AC impedance tester needs to be constantly adjusted. The control switches on the AC impedance tester are mostly push-type or rotary switches, which are easy to use. However, when the parameters of the AC impedance tester are constantly adjusted, the operator's hand moves a large range, which makes it easy to misoperate the control switch, affecting the use of the AC impedance tester. Summary of the Invention

The middle of the bottom of the connecting rod 2022 is fixedly connected to a return spring 2024. The bottom of the return spring 2024 is fixedly connected to the inner bottom wall of the ball 2021. By setting the return spring 2024, the return spring 202 4 is fixed between the inner bottom wall of the ball 2021 and the bottom of the connecting rod 2022. The return spring 2024 supports the ball 2021. After the push switch 207 is operated, the elastic force of the return spring 2024 can reset the ball 2021 to its initial state, which is convenient for the next use of the power control component 2.

The bottom of the pressing rod 2025 passes through the arc groove 205 and presses on the top of the press switch 207, which can turn on the tester 1. The ball 2021 is turned in the opposite direction to turn off the tester 1. In this way, the power control component 2 can be prevented from being accidentally touched and causing the tester 1 to be turned on or off.

[0037] In the technical solution of this application, Figure 1 、 Figure 6 and Figure 7As shown, a mounting base 3 is embedded on one side of the tester 1, a socket 4 is embedded in the middle of the mounting base 3, a socket hole is opened in the middle of the socket 4, and a locking component 5 is embedded on the upper and lower sides of the interior of the mounting base 3.

A pressure plate 504 is fixedly connected to one side. After the connector of the test line is inserted into the socket of the socket 4, the rebound force of the thrust spring 503 pushes the movable plate 502, so that the pressure plate 504 is stuck on the outer surface of the connector, and the connector is firmly plugged into the inside of the socket. When the test line is in use, even if it vibrates, the connector in the socket will not be thrown off, so that the socket 4 and the connector can be firmly engaged, so that the tester 1 will not be interrupted due to poor signal transmission during testing, and can accurately and efficiently complete the calibration and detection work.

[0038] In the technical solution of this application, Figure 6 and Figure 7 As shown, the top and bottom of the socket 4 are provided with a penetrating square groove (not shown in the figure), the pressure plate 504 passes through the square groove on the side away from the movable plate 502 and extends to the inside of the socket hole (not shown in the figure), and both sides of the movable plate 502 are fixedly connected with a guide rod 505.

[0040] Specifically, such as Figure 1-Figure 7 As shown, a control method for a high-precision AC impedance test device includes the following steps:

[0041] S1. Insert the connector of the test line into the socket of the socket 4. As the connector continues to enter, the spiral structure of the thrust spring 503 is compressed, and at the same time, elastic force is generated. The movable plate 502 slides on the inner wall of the sleeve 501, and the guide rod 505 slides inside the guide groove 506, so that the two opposing pressure plates 504 are separated.

[0042] S2. When the connector is inserted to the point where it cannot move, release the connector. At this time, the rebound force of the thrust spring 503 pushes the movable plate 502, so that the pressure plate 504 is stuck on the outer surface of the connector, firmly inserting the connector into the inside of the socket.

[0043] S3. After the tester 1 is connected to the test line and power line as required, move the ball 2021 to the left in the on direction, the bottom of the pressing rod 2025 moves to the right at the top of the arc rod 204, and the connecting rod 2022 slides inside the slide groove 2023. After the pressing rod 2025 slides into the inside of the arc groove 205, it presses the ball 2021 downward, and the ball 2021 moves downward.
