Description

Technical Field

[0001] The utility model relates to the technical field of current testing equipment, in particular to a high-precision large-current testing tooling. Background Technique

[0002] To ensure the normal operation of electromagnetic flaw detection equipment, the modules responsible for alternating current and direct current inside electronic equipment need to be tested and calibrated. Among them, shunts are usually used for the direct current modules, and current transformers are used for the alternating current modules. To ensure the quality of the flaw detection equipment and the sensitivity of flaw detection, a ring-shaped test block is also needed to test the important performance of the equipment during the test. Therefore, the ring-shaped test block also needs to be tested and calibrated. The starting current tooling is used to test the current generated by the equipment at the moment of startup. The detection of the starting current is a necessary test item in the testing of many electrical equipment. Especially for some equipment with high power supply requirements such as high-speed rails, too large starting current will directly cause the equipment to be broken down and even affect the operation of other equipment. Some existing starting current testing toolings are composed of scattered power supplies, circuit boards, cables, etc.

[0003] The existing publicly disclosed patent (publication number: CN219935938U) discloses a current testing tooling, including a frame body. The frame body includes two columns. Conductive bars for connecting with magnetization electrodes are arranged on both columns. A driving member is arranged on one of the columns. A fixed copper bar and a sliding copper bar are arranged between the two columns. A test rod for sleeving a ring-shaped test block is arranged between the fixed copper bar and the sliding copper bar. One end of the test rod abuts against the fixed copper bar, and the other end abuts against the sliding copper bar. The sliding copper bar is slidably connected with the frame body. The fixed copper bar is fixedly connected with one of the columns. The upper end of the fixed copper bar abuts against the conductive bar on the corresponding column. A driving member is arranged on the column not fixedly connected with the fixed copper bar. The driving member is used to drive the sliding copper bar to move between the two columns. When the sliding copper bar slides, the upper side of the sliding copper bar always abuts against the conductive bar. Clamping and energizing can test the components on the test rod, and the test rod can also be replaced with a shunt.

[0004] However, there are some problems in the use of the existing current testing tooling. There is a lack of a measure for overall adjustment and protection in the current testing tooling on the market at present. As a result, problems such as unstable current and reduced accuracy are likely to occur in the current testing environment, making the overall testability of it low and not convenient for use.
