Transformer short circuit impedance test power line take-up and pay-off device

The invention discloses a transformer short-circuit impedance test power line take-up and pay-off device, relates to the technical field of transformer detection, and solves the problems that a power line of transformer test equipment in the prior art is easy to wind and pull other equipment or articles during take-up and pay-off, so that the test operation is inconvenient, and the take-up and pay-off working time is relatively long. According to the technical scheme, the device comprises an automatic winding mechanism and a data detection mechanism installed on the automatic winding mechanism, the automatic winding mechanism comprises a power line winding mechanism and a power line guiding mechanism, the power line winding mechanism comprises a frame type support, and a roller used for winding a power line and a driving device used for driving the roller are rotationally installed on the support. The power line winding and unwinding device is mainly used in the power line winding and unwinding process, the g
