HIGH VOLTAGE ELECTRIC APPLIANCE

摘要

PROBLEM TO BE SOLVED: To provide a highly reliable high voltage electric appliance by inhibiting the deficient insulation mainly in a high voltage connection part. SOLUTION: In the high voltage connection part 13-11 of an ion beam processing observation pattern producing device 1 as the high voltage appliance, a filling material for preventing dew concentration and humidity absorption is filled in the gap 13-113 between a connection bushing 13-111 on the transmitting side and a flange 13-112 on the receiving side, so that the increase of leak currents is inhibited and the dielectric strength is increased.
