DETACHABLE PRIMARY POWER CONNECTIONS FOR TWO MODULES OF GAS-INSULATED HIGH-VOLTAGE SWITCHGEAR Russian patent published in 2015 - IPC H02B13/00 

FIELD: electricity.

SUBSTANCE: invention relates to electrical engineering. The gas-insulated high-voltage switchgear has the first module 1 and the second module 2 containing gaseous cavity 15, 16 made as a high-pressure vessel with at least two phase conductors. The first module is connected to the second module so that the first gaseous cavity and the second gaseous cavity are separated from each other hydraulically by an insulating body 26 while phase conductors in the first module are connected electrically with phase conductors of the same electric potential of the second module. Both gaseous cavities for each phase conductor have attaching hole, which surrounds the respective phase conductor and is outputted to a flange-shaped transition section 19, 20. The flange-shaped transition section of the first module is made with potential mechanical detachable connection with flange-shaped transition section of the second module. At least two phase conductors in the first module are made with potential electric connection of at least two phase conductors of the same potential in the second module through a detachable pluggable connection 12. At that two gaseous cavities are separated from each other by the compound insulating body.

EFFECT: improved connection of two modules.
