Description

A tooling for testing the aging of current transformers Technical Field

[0001] This utility model relates to the field of current transformer aging detection technology, specifically to a current transformer aging detection tooling. Background Technology

[0002] Current transformer aging testing refers to the process of detecting and evaluating the performance degradation of current transformers caused by factors such as time and environment during use.

[0003] For ease of testing, the test fixture of the current transformer is usually placed on a trolley, forming a flexible testing tool. Since there is no connection between the test fixture and the trolley, the test fixture is prone to displacement or even falling off when pushed out or accidentally touched during testing, which seriously affects the test results of the current transformer and poses a safety hazard. Summary of the Invention

[0004] This invention addresses the technical problem that the detection seat is prone to displacement or even falling off when the trolley moves or is accidentally touched during testing, ensuring the stability of the detection plate and effectively improving detection accuracy and safety.

[0005] The technical solution adopted by this utility model is to provide a current transformer aging detection fixture, including a frame, casters mounted on the lower end of the frame, a platform plate mounted on the frame, a detection plate mounted on the platform plate, and a detection groove mounted on the detection plate. It also includes a positioning seat mounted on the platform plate, wherein the positioning seat includes a positioning plate mounted on the platform plate, a positioning groove mounted on the upper end of the positioning plate, slide blocks mounted on the upper ends of both sides of the positioning plate, a slide groove mounted on the upper end of the slide blocks, a slide plate mounted on the upper end of the slide blocks, a slider mounted on the lower end of the slide plate and adapted to the slide groove, a screw mounted on the slide plate, and a clamping head mounted on the lower end of the screw.

[0006] The detection plate is set in the positioning groove, and the two ends of the slide plate are respectively placed on the upper ends of the two slide blocks and are slidably connected to the slide groove through the slider. The slide plate and the detection plate are vertically aligned, and the lower end of the screw passes through the screw hole and is fixed to the upper end of the clamping head.

[0007] The positioning groove has a groove structure that is open at the front and closed at the rear.

[0008] The detection slots are arranged in an equidistant array of multiple slots.

[0009] The positioning slots are arranged side by side and spaced apart, and are located between the slides.

[0010] The position of the clamping head corresponds to that of the detection groove.

[0011] The beneficial effects of this utility model are that it provides a current transformer aging test fixture, and adds a positioning seat to limit the test plate, ensuring the stability of the test plate and effectively improving the test accuracy and safety. Attached Figure Description

Detailed Implementation

[0017] As shown in Figures 1-4, this utility model provides a current transformer aging test fixture, including a frame 1, casters 2 at the lower end of the frame 1, a platform plate 3 on the frame 1, a test plate 5 on the platform plate 3, and a test groove 6 on the test plate 5. It also includes a positioning seat 4 on the platform plate 3. The positioning seat 4 includes a positioning plate 7 on the platform plate 3, a positioning groove 8 on the upper end of the positioning plate 7, slide blocks 9 on both sides of the upper end of the positioning plate 7, a sliding groove 10 on the upper end of the slide blocks 9, a sliding plate 11 on the upper end of the slide blocks 9, a slider 12 at the lower end of the sliding plate 11 and adapted to the sliding groove 10, a screw 13 on the sliding plate 11, and a clamping head 14 at the lower end of the screw 13. The test plate 5 is disposed in the positioning groove 8. The two ends of the sliding plate 11 rest on the upper ends of the two slide blocks 9 and are slidably connected to the sliding groove 10 through the slider 12. The sliding plate 11 and the test plate 5 are vertically aligned. The lower end of the screw 13 passes through a screw hole and is fixed to the upper end of the clamping head 14.

[0018] The positioning plate 7 is fixed to the platform plate 3 by welding, bolts, etc. The positioning groove 8 on the positioning plate 7 is adapted to the detection plate 5, so the detection plate 5 can be placed in the positioning groove 8. The positioning groove 8 limits the detection plate 5 and ensures that the detection plate 5 will not shake. The sliding plate 11 is slidably set above the positioning plate 7, corresponding vertically to the detection plate 5 placed in the positioning groove 8. The screw 13 on the sliding plate 11 rotates, driving the clamping head 14 to move down, clamping the detection plate 5 and further limiting the detection plate 5. The clamping head 14 is made of soft material, such as silicone or rubber, so it will not damage the detection plate 5. The sliding plate 11 can be manually pushed to the rear of the positioning plate 7 without hindering the placement and removal of the detection plate 5. It is convenient to use and simple to operate. This design can limit the detection plate 5 and improve the stability of the detection plate 5 on the trolley. The detection plate 5 is equipped with a matching printed circuit and connecting cable for electrical connection to the testing instrument for testing.

[0019] As shown in Figures 2-4, the positioning groove 8 has a groove structure that is open at the front and closed at the rear. This structure of the positioning groove 8 makes it easier to place and remove the detection plate 5.

[0020] As shown in Figure 1, multiple detection slots 6 are arranged in an equidistant array. This allows for the placement of more current transformers, resulting in higher detection efficiency.

[0021] As shown in Figure 3, multiple positioning slots 8 are arranged side by side and spaced apart, located between the slides 9. Each positioning slot 8 corresponds to a detection plate 5, which can be used flexibly according to the actual situation.

[0022] As shown in Figure 4, the clamping head 14 and the detection groove 6 are positioned accordingly. This ensures that the clamping head 14 will not press against the current transformer under test.
