Description

Technical Field

[0001] The utility model relates to the technical field of transformer production equipment, in particular to an electrical performance testing device for a semi-finished transformer. Background Art

[0002] The transformer in the prior art is composed of a frame wrapped with enameled wire turns and a plurality of magnetic cores. The semi-finished transformer assembled by the turns, the frame and the magnetic cores not only needs to be encapsulated by glue filling, but also needs to be fixed by fixing parts before the finished transformer can be formed.

[0003] Before the semi-finished transformer is encapsulated by glue, the electrical performance of the semi-finished transformer must be tested first, so as to reduce the waste of labor and materials caused by defective products entering the glue encapsulation, and reduce the waste of materials and labor losses caused by rework and disassembly of defective products after glue encapsulation.

[0004] Since the semi-finished transformer is not encapsulated with glue, the electrical performance test cannot be carried out directly on the semi-finished transformer that has not been tightened.

[0005] The prior art uses a fixing clamp to clamp the top and bottom surfaces of a semi-finished transformer to be tested, and then performs an electrical performance test on the clamped semi-finished transformer.

[0006] Due to processing errors in the fixing clamps, or elastic deviations in some fixing clamps due to deformation, the magnetic cores in the clamped semi-finished transformer to be tested are offset, resulting in a smaller contact surface between the magnetic cores, or a gap between two adjacent magnetic cores, which affects the accuracy of the test results of the inductance test project, and thus leads to an increase in the amount of rework of unqualified inductance products, resulting in an increase in related rework costs and material waste.

[0068] The bottom surface of the pressing plate 262 is used to press downward against the middle of the top surface of the semi-finished product 103 to be inspected, and the two twisting claw clamps 2661 are used to clamp the two sides of the top of the semi-finished product 103 to be inspected.

[0069] Figure 1-7 It is a structural schematic diagram of the electrical performance testing device of the semi-finished transformer of the utility model.

[0070] In the figure, the direction indicated by the X-axis is the direction of the test rotating disk 21 for feeding and outputting the semi-finished product 103 to be tested that has completed the test. The loading station 210 and the unloading station 212 are located on a straight line passing through the center point of the test rotating disk 21 and extending along the X-axis line; the direction indicated by the Y-axis is the direction of the position of the inductance detection station 2111 relative to the X-axis direction, and the direction indicated by the Z-axis arrow is the upward direction.

[0071] It should be noted that the semi-finished product 103 to be inspected is a transformer semi-finished product whose top and bottom surfaces are clamped by a fixing clamp 101, and each station of the test rotating disk 21 is equipped with a placement rack 104 for placing the semi-finished product 103 to be inspected, and the two lead ends of the turns of the semi-finished product 103 to be inspected located at any inspection station 211 extend outward in a direction away from the center point of the test rotating disk 21 so as to be electrically connected to the corresponding inspection module 22.

When the semi-finished product 103 to be detected is pressed by the pressing jaw 266, or the semi-finished product 103 to be detected is pressed by the pressing jaw 266 and the rotating torsion motor 265 is rotated, the inductance detection value of the semi-finished product 103 to be detected changes and meets the quality requirements, it can be considered that the inductance of the semi-finished product 103 to be detected meets the quality requirements and can be determined as a qualified product.
