[0002] Instrument transformers, also known as instrument transformers, are a general term for current transformers and voltage transformers. They are primary equipment that connects primary and secondary electrical systems. Instrument transformers convert high voltage and high current of the primary system into low voltage and low current for use by measuring instruments, relay protection and automatic devices of the secondary system. They are both the communication element between the primary and secondary systems in the power system and the isolation element.

[0003] See attached Figure 1 The present invention relates to a mutual inductor, which comprises a carrier and a copper column. A through hole is provided in the middle of the carrier, and a column is provided at one end of the carrier. Two pins are provided on the top of the column. When inspecting the mutual inductor, the copper column needs to be passed through the through hole into the carrier, and then the two ends and the pins of the copper column are inspected one by one by a hand-held electric clamp. This inspection method cannot inspect the copper column and the pins at the same time, so the inspection efficiency is very low. At the same time, visual fatigue is easy to occur during manual inspection, resulting in missed inspection or false inspection, and the inspection quality cannot be guaranteed.

For ordinary technicians in this field, the specific meanings of the above terms in the present utility model can be understood according to specific circumstances.

[0040] See attached Figure 1 , discloses a structure of a mutual inductor, the mutual inductor 39 comprises a carrier 1, a copper column 2 is provided on the carrier 1, and a column is provided at one end of the carrier 1, and two pins 3 are provided on the top of the column. Now, the copper column 2 needs to be inserted into the carrier 1, and the two ends of the copper column 2 and the pins 3 are energized for detection. The specific scheme is as follows;

[0041] See attached Figure 2-5, shown is a transformer detection device, including a base plate 4, on which a conveying unit, a detection unit and a picking unit are arranged in sequence, wherein the picking unit includes a return slide 38 bolted to the base plate 4, and a carrier 22 for carrying a transformer 39 is arranged in the return slide 38, and a path is provided for the carrier 22 through the return slide 38, and the return slide 38 is composed of a plurality of limit stop bars connected end to end, and a first push plate 18, a second push plate 19, a third push plate 20 and a fourth push plate 21 are respectively arranged at the four corners of the return slide 38, and the first push plate 18, The second push plate 19, the third push plate 20 and the fourth push plate 21 are located on the other side of the base plate 4 and are respectively equipped with a push drive cylinder 28. When in use, the push drive cylinder 28 drives the first push plate 18, the second push plate 19, the third push plate 20 and the fourth push plate 21 to move alternately, thereby transporting the mutual inductor 39 along the return slide 38 to the detection unit for detection. It can be seen that the mutual inductor 39 is picked up to the detection unit by the conveying unit instead of manually, thereby reducing the labor intensity of the staff, saving a labor force, and reducing the detection cost;

[0042] See attached Figure 6 As shown, the carrier 22 includes a bottom plate 23, two vertical plates 24 are arranged in parallel on the bottom plate 23, the top bolts of the two vertical plates 24 are installed on the carrier plate 25, and a receiving cavity 26 for placing the carrier 1 is opened on the carrier plate 25, and a through hole 27 is arranged at the bottom of the receiving cavity 26. When placing the mutual inductor 39, the carrier 1 is placed in the receiving cavity 26, and the copper column 2 is passed through the through hole 27 from the carrier 1, so as to replace the manual hand-held mutual inductor 39 for detection;

[0043] See attached Figure 7 As shown, the detection unit includes a first gantry 5, on which a first sliding drive cylinder 7 is vertically installed, and an output end bolt of the first sliding drive cylinder 7 is installed with a first clamping drive cylinder 12, and the first clamping drive cylinder 12 is located directly above the carrier 22, and an insulator 29 is connected to the output end bolt of the first clamping drive cylinder 12, and a first electric clamping claw 15 for detection is provided on the insulator 29, and when in use, the mutual inductor 39 is transported to the bottom of the first clamping drive cylinder 12 by the conveying unit, and then the first sliding drive cylinder 7 drives the first clamping drive cylinder 12 to move downward so that one end of the copper column 2 is placed between the two first electric clamping claws 15, and then the first clamping drive cylinder 12 drives the first electric clamping claw 15 to clamp the copper column 2;

[0044] The detection unit also includes a second sliding drive cylinder 8 located below the first sliding drive cylinder 7, the second sliding drive cylinder 8 is fixed on the substrate 4, a second clamping drive cylinder 13 is provided on the output end of the second sliding drive cylinder 8, the output end of the second clamping drive cylinder 13 is connected to the second electric clamp 16 through an insulator 29, and a third clamping drive cylinder 14 is provided on the top of the output end of the second sliding drive cylinder 8, the output end of the third clamping drive cylinder 14 is provided with a third electric clamp 17 through an insulator 29. When in use, the first sliding drive cylinder 7 and the second sliding drive cylinder 8 act simultaneously, and the second clamping drive cylinder 13 and the third clamping drive cylinder 14 are driven to extend toward the carrier 22 through the second sliding drive cylinder 8, and the other end of the copper column 2 and the pin 3 are respectively placed on the second electric clamp. 16 and the third electric clamp 17, at this time, the first clamping drive cylinder 12, the second clamping drive cylinder 13 and the third clamping drive cylinder 14 act simultaneously to clamp the two ends of the copper column 2 and the pin 3. It can be seen that when the mutual inductor 39 is detected, the push drive cylinder 28 is used to transport the carrier 22 carrying the mutual inductor 39 along the return slide 38 to the bottom of the first sliding drive cylinder 7, and the mutual inductor 39 is detected by the simultaneous action of the first electric clamp 15, the second electric clamp 16 and the third electric clamp 17, thereby replacing manual labor to detect the two ends of the copper column 2 and the pin 3 one by one, and replacing manual labor with mechanical detection, thereby improving the detection efficiency, and also eliminating the occurrence of missed detection and false detection due to visual fatigue in manual detection, thereby ensuring the quality of detection;

[0045] See attached Figure 7 As shown, in order to realize the detection of the mutual inductor 39, the first electric clamping jaw 15, the second electric clamping jaw 16 and the third electric clamping jaw 17 are provided with a terminal 30. When in use, the terminal 30 is connected to the cable to make the first electric clamping jaw 15, the second electric clamping jaw 16 and the third electric clamping jaw 17 energized and then detect, and at the same time, the insulator 29 is used to avoid the danger of the whole device being energized;

[0046] See attached Figure 2 , Attachment Figure 3As shown, a pickup unit is provided on one side of the substrate 4 located at the detection unit, and the pickup unit includes a second gantry 6, a synchronous pulley group 33 is provided on the second gantry 6, one end of the synchronous pulley group 33 is provided with a driving motor 34, and a connecting block 35 is connected to the synchronous pulley group 33, and a third sliding drive cylinder 9 is installed on the connecting block 35 by bolts, and a pickup drive cylinder 31 is provided at the output end of the third sliding drive cylinder 9, and a pickup clamp 32 is provided at the output end of the pickup drive cylinder 31, and a conveyor belt 11 is provided on one side of the substrate 4 located at the second gantry 6, and the conveyor belt 11 is driven by a motor. When the mutual inductor 39 fails to meet the test of the detection unit during use, the mutual inductor 39 on the carrier 22 is grabbed by the picking drive cylinder 31 and transported to the conveyor belt 11 for collection under the cooperation of the driving motor 34 and the synchronous pulley group 33, thereby avoiding the mixing of defective products into qualified products due to human negligence;

[0047] See attached Figure 2 , Attachment Figure 3 As shown, the substrate 4 is located on the other side of the detection unit and is provided with a fourth sliding drive cylinder 10 through a column. The output end of the fourth sliding drive cylinder 10 is provided with a top block 37. When in use, manpower only needs to pre-insert the copper column 2 into the carrier 1, and then transport it to the bottom of the top block 37 through the return slide 38, and then the top block 37 is driven by the fourth sliding drive cylinder 10 to press the copper column 2 into the carrier 1, thereby realizing the mechanized installation of the copper column 2 on the carrier 1, which not only improves the degree of mechanization, but also replaces manpower to ensure the quality of the installation of the copper column 2.

[0048] See attached Figure 8 , Attachment Fig. 9 As shown, during the inspection, the copper column 2 is first pre-inserted into the carrier 1 of the mutual inductor 39, and then the mutual inductor 39 is sequentially placed in the accommodating cavity 26 of the carrier 22 in the roundabout slide 38, and then the push drive cylinder 28 drives the first push plate 18, the second push plate 19, and the third push plate 20 to alternately push the carrier 22 carrying the mutual inductor 39 clockwise. When the mutual inductor 39 reaches the fourth sliding drive cylinder 10, the top block 37 is used to press the copper column 2 into the carrier 1, and then the carrier 22 is pushed to the detection unit. The first sliding drive cylinder 7 and the second sliding drive cylinder 8 are simultaneously driven to push the first clamp 22 respectively. The holding drive cylinder 12, the second clamping drive cylinder 13 and the third clamping drive cylinder 14 move toward the mutual inductor 39 until the two ends of the copper column 2 and the pin 3 are respectively placed between the first electric clamp 15, the second electric clamp 16 and the third electric clamp 17, and then the first clamping drive cylinder 12, the second clamping drive cylinder 13 and the third clamping drive cylinder 14 act simultaneously to clamp the two ends of the copper column 2 and the pin 3 for detection. When the detection is unqualified, the third sliding drive cylinder 9 is used to cooperate with the picking drive cylinder 31 to grab the defective products and collect them on the conveyor belt 11, while the qualified mutual inductors 39 can be collected by the staff.

[0049] It should be noted that the first sliding drive cylinder 7 and the second sliding drive cylinder 8 are both slide cylinders, and the first clamping drive cylinder 12, the second clamping drive cylinder 13, the third clamping drive cylinder 14 and the picking drive cylinder 31 are all clamping cylinders.
