As shown in fig. 1, in one embodiment, a high voltage detection apparatus 10 for a transformer includes: support 300, first insulating strip 100, second insulating strip 200, first guide 120 and second guide 220, first insulating strip 100 with second insulating strip 200 set up in on the support 300, first insulating strip 100 with second insulating strip 200 is parallel, first insulating strip 100 dorsad first storage tank 110 has been seted up to the one side of support 300, second storage tank 210 has been seted up to second insulating strip 200 dorsad the one side of support 300, first guide 120 set up in first storage tank 110, second guide 220 set up in second storage tank 210. A large number of transformers are arranged on the first guide piece 120 and the second guide piece 220, pins on one side of each transformer abut against the first guide piece 120, pins on the other side of each transformer abut against the second guide piece 220, and then high-voltage test pens are electrically connected to the same side of the first guide piece 120 or the second guide piece 220, so that high-voltage test can be simultaneously carried out on the transformers, and the detection efficiency is improved. And through setting up first storage tank 110 and second storage tank 210 for each transformer can arrange in an orderly manner, makes the detection more quick, accurate.

In order to better place the transformer on the first conductive sheet 120, as shown in fig. 1, in one embodiment, a plurality of first pin slots 130 are formed in a surface of the first conductive sheet 120 facing away from the bracket 300, and each first pin slot 130 is located on the same straight line. The pins of the transformer are confined by the sidewalls of the surrounding first leg grooves 130 by being placed in the first leg grooves 130.

In order to better place the transformer on the second conductive sheet 220, as shown in fig. 1, in one embodiment, a plurality of second pin grooves 230 are formed in a surface of the second conductive sheet 220 facing away from the bracket 300, and the second pin grooves 230 are located on the same straight line. When both sides of the transformer are restricted by the first leg groove 130 and the second leg groove 230, the placement of the transformer can be more stable.

Since the pins on both sides of the transformer are generally aligned, in order to allow the transformer to be simultaneously sunk into the first pin and the second pin, as shown in fig. 1, in one embodiment, each of the first pin slots 130 is aligned with one of the second pin slots 230. When a pin on one side of the transformer is sunk into the first pin groove 130, a pin disposed opposite to the pin is also sunk into the second pin groove 230.

Since the two rows of pins on both sides of the transformer are generally parallel, in order to limit the pins on both sides of the transformer, as shown in fig. 1, in one embodiment, the straight line of each first pin slot 130 is parallel to the straight line of each second pin slot 230. When two pins are placed in the first pin or the second pin on the transformer, two rows of pins arranged in parallel on the transformer are correspondingly placed in the corresponding first pin or the second pin.

In order to accommodate more types of transformers, as shown in fig. 1, in an embodiment, a plurality of sets of third pin grooves 140 are formed in a surface of the first conductive sheet 120 facing away from the bracket 300, a straight line where each set of third pin grooves 140 is located is parallel to a straight line where the first conductive sheet 120 is located, a plurality of sets of fourth pin grooves 240 are formed in a surface of the second conductive sheet 220 facing away from the bracket 300, an axis where each set of fourth pin grooves 240 is located is parallel to a straight line where the second conductive sheet 220 is located, each set of third pin grooves 140 is aligned with one set of fourth pin grooves 240, and a distance between each corresponding third pin groove 140 and each corresponding fourth pin groove 240 gradually increases from one end of the first insulating strip 100 to the other end of the first insulating strip 100. Because the distances between the pins on the two sides of different transformers may be different, by arranging the opposite sets of the third pin slot 140 and the fourth pin slot 240 with different distances on the first conductor and the second conductor, different transformers can be placed in the third pin slot 140 and the fourth pin slot 240 by changing the positions of the transformers, so that more different types of transformers can be stably placed in the third pin slot 140 and the fourth pin slot 240.

Since the number of pins on both sides of many transformers is two and four, respectively, in order to better adapt such transformers, as shown in fig. 1, in one embodiment, each set of the third sub-slots 140 includes two third sub-slots 141, each set of the fourth sub-slots 240 includes four fourth sub-slots 241, and the distance between the two third sub-slots 141 is equal to the maximum distance between the two third sub-slots 141. The number of the corresponding group of the third leg slots 140 and the fourth leg slots 240 is set to two and four, respectively, so that the transformer is better placed on the first guide piece 120 and the second guide piece 220, and in addition, the third sub slots 141 and the fourth sub slots 241 on two sides are distributed differently, and the third leg slots 140 and the fourth leg slots 240 in different groups.

Since the pins on the transformer may be slightly offset, in order to better fit the pins into the third and fourth leg slots 140 and 240, as shown in fig. 1, the cross-sectional shapes of the third and fourth leg slots 140 and 240 are circular in one embodiment. If the transformer pin is rectangular and the third leg slot 140 or the fourth leg slot 240 is also rectangular, the transformer pin may not be inserted into the third leg slot 140 or the fourth leg slot 240 when the transformer pin is deflected, and the circular third leg slot 140 and the circular fourth leg slot 240 can relatively better accommodate the deflected pin.

In order to adjust the distance between the first insulating strip 100 and the second insulating strip 200, as shown in fig. 1, in one embodiment, the bracket 300 includes a first division bar 310, a plurality of first inserting holes 311 are respectively opened at two ends of the first division bar 310, the first inserting holes 311 at the two ends are symmetrically arranged, and the first insulating strip 100 and the second insulating strip 200 are respectively inserted into two symmetrical first inserting holes 311. When the distance between the pins on both sides of the transformer is large, the distance between the first pin slot 130 and the second pin slot 230 on both sides can be increased by adjusting the relative position of the first insulating strip 100 or the second insulating strip 200 inserted in the first spacing strip 310, so that the pins on both sides of the transformer can be placed in the first pin slot 130 and the second pin slot 230.

In order to enable the first insulating strip 100 and the second insulating strip 200 to be placed on the bracket 300 more stably, as shown in fig. 1, in an embodiment, the bracket 300 includes a second division bar 320, two ends of the second division bar 320 are respectively provided with a plurality of second insertion holes 321, the second insertion holes 321 at the two ends are symmetrically arranged, each second insertion hole 321 is aligned with one first insertion hole 311, one end of the first insulating strip 100 is inserted into one first insertion hole 311, the other end of the first insulating strip is inserted into the second insertion hole 321, one end of the second insulating strip 200 is inserted into the other first insertion hole 311, and the other end of the second insulating strip is inserted into the other second insertion hole 321. By inserting both ends of first insulation bar 100 and second insulation bar 200 into first division bar 310 and second division bar 320, respectively, fixing is performed from both sides, so that first insulation bar 100 and second insulation bar 200 are more stable. It should be understood that the width of the first slot 311 or the second slot 321 opposite to each other on the first parting strip 310 or the second parting strip is set according to the actual first insulating strip 100 and the second insulating strip 200, so that the first insulating strip 100 abuts against the side wall of the first slot 311, and the first insulating strip 100 abuts against the side wall of the second slot 321; the second insulating strip 200 abuts against a side wall of the first socket 311 and the second insulating strip 200 abuts against a side wall of the second socket 321.
