Description

Technical Field

[0001] The utility model relates to the technical field of voltage transformer detection, in particular to a voltage transformer detection device. Background Art

[0002] Voltage transformer is an instrument used to transform the voltage on the line. At present, the voltage transformer is tested by clamping the pins with a clip. This test method has slow test speed and low efficiency. In addition, the clip is easily damaged when used for a long time, and the test is difficult and the tester is easily fatigued, which causes inaccurate test structure. Therefore, the existing Chinese patent with authorization announcement number CN207352151U discloses a voltage transformer test tool, including a fixed plate made of insulating material, a leg and an elastic contact, the legs are fixed at both ends of the bottom of the fixed plate, the fixed plate and the legs form a door-shaped bracket, and the fixed plate is provided with a mounting hole for installing the elastic contact. The mounting hole passes through the upper and lower surfaces of the fixed plate, and the elastic contact is arranged therein. The top of the elastic contact is lower than the upper surface of the fixed plate, and its lower end is connected to the test terminal of the voltage transformer tester through a wire. When the voltage transformer test tool of the utility model is used to test the voltage transformer, the tester only needs to hold the product with his hands and align the four pins with the four elastic contacts on the test work, which is convenient to operate. Furthermore, the contacts of the voltage transformer test fixture are elastic contacts, which are provided with compression springs, thereby ensuring the reliability of the contact and improving the accuracy of the test structure.

[0003] However, in actual applications, the above test fixture still has the following shortcomings: it is difficult to manually align the four pins of the voltage transformer with the conductive contacts before testing, resulting in low detection efficiency. In addition, the detection position is different for different models of the same voltage transformer, but the position of the conductive contacts in the above test fixture is fixed, resulting in the above test fixture being only applicable to one model of voltage transformer testing, and its applicability is extremely poor.
