[0002] When installing the voltage transformer of the ring main unit cabinet, it is necessary to align the screw holes of the transformer with the screw holes on the mounting plate, and then bolts can be used to fix the transformer to the mounting plate. During the installation process, multiple people need to cooperate to control the alignment of the screw holes on the transformer with the screw holes on the mounting plate, which is relatively inconvenient.

[0003] Therefore, a device capable of assisting in the installation of the voltage transformer is needed to align the screw holes on the voltage transformer with the screw holes on the mounting plate, so as to facilitate the use of bolts to fix the transformer to the mounting plate. Summary of the Utility Model

[0004] The purpose of the utility model is to provide an installation device for a voltage transformer of a ring main unit cabinet to solve the above problems.

[0005] In order to achieve the above purpose, the utility model adopts the following technical scheme:

[0006] The installation device for a voltage transformer of a ring main unit cabinet includes a mounting plate and a device body. A chute is provided on the device body. A vertical plate is fixed on the mounting plate, and a connecting groove is provided on the vertical plate. A stop rod is slidably connected to the connecting groove and the chute. A connecting plate is fixed on the mounting plate, and a sliding rod fixed on the stop rod is slidably connected to the connecting plate. A limiting member for limiting the stop rod is provided on the connecting plate.

[0007] Preferably, the limiting member includes a fixed ring fixed on the connecting plate, and the fixed ring is threadedly connected with a sleeve block. The sleeve block is sleeved on the end of the sliding rod, and a matching member is further provided on the sliding rod to cooperate with the sleeve block.

[0008] Preferably, the matching member includes a spring sleeved on the sliding rod, and the sliding rod is slidably connected to a through hole provided on a moving block. A clamping rod is fixed on the moving block, and a transverse hole for the clamping rod to slide through is provided on the connecting plate. A clamping groove corresponding to the transverse hole is provided on the sleeve block.

[0009] Preferably, one end of the spring is fixedly connected to the stop rod, and the other end is fixedly connected to the moving block.
