Transformer high pressure pile head test electrode and transformer

The utility model provides a transformer high pressure pile head test electrode and transformer relates to the electric power part field, include: survey test bar and insulating sheath survey test bar's one end and are connected with high -pressure pile head line board, and the other end is the free end, and the free end is used for being connected with electric experimental test instrument, all are provided with the insulating layer outside the high -pressure pile head line board and outside survey test bar and the high -pressure pile head line board junction, the free end overcoat of surveying test bar is equipped with insulating sheath. Outside outside with surveying test bar and high -pressure pile head line board junction at high -pressure pile head line board all sets up the insulating layer, only expose the free end of surveying test bar, because winding electric tape takes off outside need not high -pressure pile head line board when the test, only need take off insulating sheath exposes the free end,
