Portable transformer partial discharge detection device

The invention relates to the technical field of discharge detection, in particular to a portable transformer partial discharge detection device which comprises a shell, a discharge detection module and a data analysis module, the discharge detection module and the data analysis module are arranged in the shell, a detection head is arranged on the discharge detection module to detect discharge conditions and collect data, and the data are transmitted to the data analysis module through electric signals. A cover plate is arranged on the shell, a connecting mechanism is arranged between the shell and the cover plate, a tool box is arranged above the discharge detection module, and a rotating mechanism is arranged between the tool box and the shell. During use, an operator only needs to take out the detection head for use, the whole discharge detection module is prevented from being taken out, when the detection device is not used, a cover plate can be closed and clamped into a limiting groove through a limiting
