[0039] Brief description of the usage process:

[0040] When in use, firstly, an external air circuit controller is connected to the air cylinder 6 and the telescopic cylinder 53, and then the utility model is suspended above the comprehensive test area of ​​the transformer by using the fixing frame 11, and the transformer 10 is moved to a specific position below the utility model by using a large transmission belt or a forklift (generally, a position indicator mark is set on the ground), and various test instruments of the comprehensive test are connected by using the connecting wire 91, and then the circuits of the test instruments and the transformer 10 need to be turned on.

[0041] When the circuit between the test instrument and the transformer 10 is turned on: the external air circuit controller is used to control the extension of the cylinder 6, and the slide 7 at the lower end of the cylinder 6 follows and descends, thereby driving the slider 8 and the connector 9 installed on the slide 7 to descend as a whole, until the connector 9 is embedded in the high-voltage connection post 101 and the low-voltage connection post 102 of the transformer 10, and the elastic spring 92 inside the connector 9 is embedded and clamped on the high-voltage connection post 101 or the low-voltage connection post 102, forming an effective electrical connection with the high-voltage connection post 101 and the low-voltage connection post 102, and the elastic spring 92 conducts the circuit between the high-voltage connection post 101, the low-voltage connection post 102 and the connection wire 91 through the conductive post 93.

[0042] After the circuits between the high-voltage connection pole 101, the low-voltage connection pole 102 and the connection wire 91 are connected, the utility model and the transformer 10 need to be relatively fixed to prevent vibration from causing the connector 9 to loosen and shift, thereby causing unnecessary safety hazards. At this time, an external air circuit controller is used to control the extension of all telescopic cylinders 53, and the telescopic cylinders 53 drive the upper part of the deflection frame 51 to deflect outward around the deflection rod 52, and then according to the lever principle, the lower part of the deflection rod 52 deflects inward, and then the beam rod 54 and the clamp rod 55 under the deflection rod 52 follow the deflection rod 52 to deflect inward, and the elastic sleeve 56 on the clamp rod 55 clamps the transformer 10, thereby preventing poor contact between the high-voltage connection pole 101, the low-voltage connection pole 102 and the connector 9 due to vibration shift, thereby reducing safety hazards and test errors.

[0043] Then, the comprehensive testing instrument connected to the connecting wire 91 can be used to test some comprehensive performances of the transformer 10. After the test is completed, the cylinder 6 and the telescopic cylinder 53 are reset by the external controller to transport the tested transformer away, and then the next group of transformers to be tested are placed at a specific position below the utility model by a large transmission belt or a forklift to carry out the comprehensive test of the next group of transformers to be tested. In this way, the streamlined comprehensive test of the transformer is completed.

[0044] When the transformer models are different, it is necessary to adjust the spacing of the slides 7 according to the transformer models, and to adjust the spacing of the connectors 9 under each group of slides 7 .

[0045] When adjusting the spacing of the slides 7, the spacing of the slides 7 is consistent with the spacing between the high-voltage connecting poles 101 and the low-voltage connecting poles 102 on the transformer 10. At this time, loosen the locking bolt 310, slide the slide 33 on the slide rod 32, and then change the spacing of the mounting seat 2 below the slide 33, and then change the spacing between the slides 7 installed on the mounting seat 2 through the cylinder 6. At this time, the indicator needle 35 and the scale line 39 are used to indicate the specific value of the spacing between the slides 7. After the spacing between the slides 7 is adjusted, re-lock the locking bolt 310.

[0046] When adjusting the spacing of the connectors 9 under each group of slides 7, the distance between the connectors 9 under each group of slides 7 is consistent with the spacing between each connection pole on the high-voltage connection pole 101 and the low-voltage connection pole 102 to be connected. At this time, loosen all the fastening bolts 82. After the fastening bolts 82 are loosened, the slider 8 and the connector 9 can slide as a whole in its corresponding slide 7. At this time, the position of the sliding slider 8 makes the spacing of the connectors 9 on it consistent with the spacing between each connection pole on the low-voltage connection pole 102 or the spacing between each connection pole on the high-voltage connection pole 101. After the adjustment is completed, re-lock the fastening bolts 82 to fix the relative position between the slide 7 and the slider 8 and the connector 9 thereon.
