COOLING OF HIGH-VOLTAGE DEVICES Russian patent published in 2012 - IPC H01B17/54 

FIELD: electricity.

SUBSTANCE: high-voltage system comprises a HVDC valve (34), including a liquid flow system (39, 40) of cooling to cool down this HVDC valve, and a high-voltage input (30) to transfer high voltage and intense current from the HVDC valve (34) cooled with fluid medium, besides, the high-voltage input (30) comprises an insulating body (12), which surrounds the electric conductor (31), electrically connected with the connector of the specified HVDC valve (34). The electric conductor (31) comprises a ventilation channel (32), which is adapted to cool down the input with the help of circulating gas fluid medium. The high-voltage system comprises a heat exchanger (300), connected with a ventilation channel and adapted for cooling of gas fluid medium. The heat exchanger is connected with the cooling system of the HVDC valve and is adapted to receive cooling water from the cooling system (39, 40) of the HVDC valve and to return heated cooling water into the cooling system.

EFFECT: improved cooling of high-voltage devices.
