Secondary voltage leading-out device of voltage transformer

The utility model provides a secondary voltage leading-out device of a voltage transformer, and the device comprises a box body which is internally provided with an accommodation cavity; the partition plate is arranged in the box body and is connected to a secondary terminal of the voltage transformer body through an external wire, and the terminal row is externally connected to an alternating current voltage sampling meter to power the voltage transformer, so that the secondary voltage of the voltage transformer is led out of the high-voltage switch cabinet to be checked and measured. By comparing a measurement result with an original secondary circuit measurement result, whether a secondary circuit fault or a voltage transformer body fault occurs can be rapidly distinguished, the troubleshooting efficiency is improved, the power failure time of equipment is shortened, the interior of the box body is divided into the first cavity and the second cavity, the first cavity is used for containing the terminal str
