Electric appliance of an electricity distribution system, method of manufacture of a device for high voltage and method for isolating a terminal of high voltage of an electrical appliance

摘要

Electric appliance of an electricity distribution system, method of manufacture of a high - voltage electrical apparatus and method for isolating a terminal of high voltage of an electrical appliance.The present invention relates to an electric appliance of an electricity distribution system which includes an electrical device (100) with a high - voltage electrical terminal (105), which can be energized, a housing for external insulation (115) and an insulator (200, 400, 500, 600 ).The carcass of external insulation (115) surrounds and isolates the electrical device (100) and includes an opening, through which the electric terminal of high voltage (105) stresses, so that at least part of high - voltage electrical terminal (105) is external to the housing of the insulation External (115).The insulator (200, 400, 500, 600) covers the electric terminal and is connected to the housing for external insulation (115) so that there is no way of current flow between a contact surface between the insulator (200, 400, 500, 600) and the housing external insulation (115).
