Abstract
The utility model provides a high voltage contact module of a zinc oxide arrester measuring device. The high voltage contact module includes a high voltage contact block, a high voltage transition block, an insulating transition block and a high voltage isolation block which are stacked together sequentially from top to bottom. With a V-shaped groove and an arc-shaped contact surface adopted, the high voltage contact block can well contact with one end of a zinc oxide arrester and a high voltage generator. When testing is performed, the high voltage transition block and the insulating transition block between the high voltage contact block and the high voltage isolation block can form an equipotential body, so that current leakage can be prevented, and therefore, the high voltage components of the zinc oxide arrester can be excellently insulated from other components, and therefore, the problem of inaccurate measurement which is caused by signal interference can be avoided.
