HIGH-TENSION SWITCHGEAR WITH METAL CASING AND COMPRESSED GAS INSULATION AND WITH AN INSULATED EARTHING SWITCH

摘要

in switches of high voltage gas insulated switches compressed using isolated ground (3) for applying voltages to the control.to this end, a ring (13) of insulating material in which is embedded a driver (14) with a bar (15) in contact with the pin switch (5) is arranged between the housing (6) and the enclosure (1). in order to improve the insulation, the insulation ring (13) is arranged in a metal ring (12) which serves as a support ring for receiving attachment (9).it is not interrupted by the bar (15) with a casing (17) of insulating material, which can greatly the ring (13) of insulating material of mechanical stress. the insulated earthing switches are used in high voltage switching devices and separated by metal plating of sf6 gas, compressed.
