The main difference lies in the small capacity of the voltage transformer, typically only tens to hundreds of volt-amperes. Currently, the production and error verification testing of electromagnetic voltage transformers are carried out separately. After production, the electromagnetic voltage transformers are transported by truck to other workshops for testing, increasing manpower and material resources.

[0003] Chinese patent CN218213402U discloses an error verification device for a 10KV electromagnetic voltage transformer. This technical solution avoids the tedious verification of electromagnetic voltage transformers by performing error verification during the production of the electromagnetic voltage transformer. The detachable installation facilitates the maintenance of the error verification device, and the electric telescopic rod can be used to adjust the height of the error verification device according to the height of the staff, thus improving its applicability.

[0004] However, this electromagnetic transformer calibration device does not have a guiding and limiting function during use. The electromagnetic transformer is prone to deviation during transportation, which requires staff to straighten the electromagnetic transformer before testing, increasing the workload of staff and reducing the efficiency of electromagnetic transformer calibration.

[0028] In this embodiment, during the process of multiple rotating rollers 2 carrying and conveying the electromagnetic transformer, the first electric telescopic rod 6 extends, causing the receiving box 7 to descend, which in turn causes the two limiting plates 13 to move to the corresponding positions of the electromagnetic transformer. After the drive mechanism works, the two limiting plates 13 can be moved closer to each other. After the inner side of the limiting plate 13 contacts the side wall of the electromagnetic transformer, the position of the electromagnetic transformer can be corrected.

The surface of the receiving box 7 is disassembled and provided with a second maintenance cover plate 28 by several second bolts 27.

By using the connection of the vertical plate 11, the distance between the two limiting plates 13 can be adjusted, which is convenient for adapting to different electromagnetic transformers for limiting work.

During this process, the first electric telescopic rod 6 extends, driving the receiving box 7 to descend, which in turn drives the two limiting plates 13 to move to the corresponding positions of the electromagnetic transformer. After the drive mechanism works, the two limiting plates 13 can be driven to move closer to each other. After the inner side of the limiting plate 13 contacts the side wall of the electromagnetic transformer, the position of the electromagnetic transformer can be corrected. After the limiting plate 13 contacts the side wall of the electromagnetic transformer, it can remain without deviation during subsequent continuous transport. After the electromagnetic transformer moves to the corresponding position of the calibration device body 22, the operator can insert the connector 24 into the interface of the electromagnetic transformer to perform calibration work.
