[0023] By setting the support plate 3 on the lower side of the console 1 as a retractable support plate 3, when it needs to be moved, it is first extended to the support plate 3 on the lower side of the transformer 2, and then the support structure 5 is retracted and extended, and the self-locking universal wheels 4 are used to alternately support the console 1 and the transformer 2, so that the console 1 and the transformer 2 can be moved at the same time. After support, they can be separated to avoid being fixedly connected together, which increases the workload of subsequent maintenance work. It is easy to use and has high practicality (the console, transformer, connection method and test method that constitute the power frequency withstand voltage test equipment here are all prior art and will not be repeated here).

[0024] In another embodiment, see Figure 1-4The lower support plate 3 of the console 1 includes a fixed plate 31, which is laterally fixed on the lower side of the console 1, and four support structures 5 are respectively arranged on the periphery of the lower side of the fixed plate 31. A sliding plate 32 is inserted and slidably inserted on the right side of the fixed plate 31, and four self-locking universal wheels 4 are fixed in pairs on the left side of the fixed plate 31 and the right side of the sliding plate 32. The sliding plate 32 can extend rightward to the lower side of the lower support plate 3 of the transformer 2, and can abut against the lower side of the lower support plate 3 of the transformer 2. A sliding cavity 33 is opened in the fixed plate 31 corresponding to the sliding plate 32, and a first limiting slider 34 connected with the sliding cavity 33 is provided on the left side of the sliding plate 32;

At the same time, during the retraction process of the support rod 52 of the transformer 2, the support plate 3 at the lower side thereof gradually moves downward until it abuts against the sliding plate 32. At this time, the control console 1 and the transformer 2 can be supported at the same time by the self-locking universal wheels 4 at the lower sides of the fixed plate 31 and the sliding plate 32.
