Background

The insulation detection of the alternating current circuit in the secondary acceptance stage of the transformer substation is an important acceptance work, and the insulation degree among all branches is still measured by adopting methods of manual wire insertion, manual data reading, manual recording and manual discharging in the current stage. Because insulation measurement requires that insulation between the branches must be measured, insulation between the branches and the ground must also be measured, insulation experiment operation is complicated, the measurement frequency is a permutation and combination mathematical problem, and labor intensity increases exponentially with the increase of the number of the branches. In addition, after the measurement is finished, manual earth discharge is needed, otherwise, the risk of breaking down the protection device and discharging high voltage exists, so that the operation is complicated and forgetting exists. The repetitive manual wire plugging, manual data reading, manual recording and manual discharging work properties are simple and repeated, but the time and the labor are extremely consumed, and certain work risks exist.
