Description

Tool is used in test of electrical device homonymy end

Technical Field

The utility model relates to the field of electric device testing jigs, in particular to a jig for testing the same name end of an electric device.

Background

The polarity discrimination of the transformer usually needs to be tested at the same-name end/different-name end, wherein the same-name end refers to the end with the same potential polarity in two (or more than two) windings at any time under the action of the same alternating magnetic flux, namely when the directions of the two windings are consistent, the winding starting points of the two windings are the same-name end, and when the directions of the two windings are opposite, the winding starting point of one winding and the ending point of the other winding are the same-name end.

For a common two-input and two-output four-terminal transformer, the common voltage comparison method is used for testing the same-name terminals, if the input terminals are (1) and (2) and the output terminals are (3) and (4), the input terminals (2) and (3) are short-circuited, the output voltage value between the input terminals (1) and (4) is measured by a testing system through 20V of the input voltages (1) and (2), if the output voltage value is larger than 20V, the input terminals (1) and (3) are the same-name terminals, otherwise, the input terminals (1) and (4) are the same-name terminals. In the operation process, four wire clamps of the testing equipment need to be clamped on four wiring terminals of the transformer in sequence, and the testing device is not suitable for rapid testing on the existing assembly line and cannot meet the high-efficiency production requirement of the assembly line.
