[0074] Refer to Figure 1 and Figure 2 , a method for testing the inter-turn insulation of the electromagnetic wire 51 of a generator stator bar 5 and a method, based on the above-mentioned testing equipment for the inter-turn insulation of the electromagnetic wire of a generator stator bar, includes the following steps:

[0075] Isolate multiple electromagnetic wires 51 at the first end of the bar 5 with the battery device 4, so that only one electromagnetic wire 51 is arranged in one card slot 4101, and the heads of the multiple electromagnetic wires 51 at this end shall not contact each other;

[0076] Isolate multiple electromagnetic wires 51 at the second end of the bar 5 with a comb plate, and ensure that the heads of the multiple electromagnetic wires 51 at this end do not touch each other. One end of the comb plate 6 in the width direction is provided with multiple upper comb teeth 61, and the other end is provided with multiple lower comb teeth 62. Clip the multiple electromagnetic wires 51 between the multiple upper comb teeth 61 and / or between the multiple lower comb teeth 62. Make one electromagnetic wire 51 clamped between two adjacent lower comb teeth 62 or between two adjacent upper comb teeth 62;

[0077] The upper pressure plate 32 and the lower pressure plate 33 are close to the electric plate device 4, and the upper pressure plate 32 and the lower pressure plate 33 press the electromagnetic wire 51 on the conductive reed 42;

[0078] Every two conductive reeds 42 are connected to a resistance measuring instrument through an electric control switch. In this application, a pressure switch is connected between each conductive reed 42 and the electric plate device 4. Every two conductive reeds 42 form a detection unit. The two pressure switches of each detection unit are connected to an electric control switch, and the electric control switch is connected to the resistance measuring instrument. The resistance measuring instrument, the pressure switch, and the electric control switch here are all prior arts;

[0079] When the upper pressure plate 32 and the lower pressure plate 33 press the electromagnetic wire 51 on the conductive reed 42, the conductive reed 42 transfers the pressure to the corresponding pressure switch, turning on the pressure switch. At this time, the detection unit corresponding to this pressure switch is connected to the corresponding electric control switch, and then the on / off of all the pressure switches can be controlled in sequence to enable the resistance measuring instrument to detect the resistance value between every two electromagnetic wires 51, and then the resistance value between every two electromagnetic wires 51 can be tested in sequence to achieve the rapid testing of the inter-turn insulation of the electromagnetic wires 51 of the generator stator bar 5.

[0080] Refer to Figure 1 and Figure 2 In the embodiment of this application, through the coordinated cooperation of the electric plate device 4, the upper pressure plate 32, and the lower pressure plate 33, all the electromagnetic wires 51 on the bar 5 can be fixed on the electric plate device 4 at one time. Then, in cooperation with the resistance measuring instrument, the resistance value between every two electromagnetic wires 51 on the bar 5 can be tested in sequence, improving the efficiency of the inter-turn insulation test of the electromagnetic wires 51 of the bar 5.

[0081] The implementation principle of the inter-turn insulation test equipment and method for the electromagnetic wires of a generator stator bar in the embodiment of this application is as follows:

[0082] Respectively clip multiple electromagnetic wires 51 at the first end of the bar 5 into a card slot 4101, and ensure that the heads of the multiple electromagnetic wires 51 at this end do not touch each other. Isolate multiple electromagnetic wires 51 at the second end of the bar 5 with a comb plate, and ensure that the heads of the multiple electromagnetic wires 51 at this end do not touch each other.

[0083] The upper pressing plate 32 and the lower pressing plate 33 are close to the battery device 4 and clamp the battery device 4, so that the upper pressing plate 32 and the lower pressing plate 33 press the electromagnetic wire 51 on the conductive reed 42. When the upper pressing plate 32 and the lower pressing plate 33 press the electromagnetic wire 51 on the conductive reed 42, the conductive reed 42 transmits the pressure to the corresponding pressure switch, causing the pressure switch to turn on. At this time, the detection unit corresponding to the pressure switch is connected to the corresponding electronic control switch, and then the on / off of all the pressure switches can be controlled in sequence to realize the detection of the resistance value between every two electromagnetic wires 51 by the resistance measuring instrument. Furthermore, the resistance value between every two electromagnetic wires 51 can be tested in sequence. If there is a short circuit or the resistance value is less than the requirement, it means that there is a short circuit or low insulation value in the electromagnetic wire, and it is determined to be unqualified. Thus, the rapid test of the inter-turn insulation of the electromagnetic wire 51 of the generator stator bar 5 can be realized.
