Description
Technical field
The present invention relates to a kind of superpower high pressure high-insulativity ceramic cartridge, extra-high voltage direct-current transmission engineering can be improved
With the pressure-resistant and insulaion resistance of IGCT, belong to electric and electronic technical field.
Background technology
Extra-high voltage direct-current transmission has turned into the primary hand of Large Copacity, long distance power delivery and interconnection of large-scale power grids in China's power grid construction
Section, China's extra-high voltage direct-current (voltage is more than 7500V, and electric current is more than 6000A) technology of transmission of electricity is in a leading position ground in the whole world at present
Position.And core devices of the IGCT as extra-high voltage direct-current transmission engineering converter valve, its individual devices bear high pressure and insulation energy
Power is mainly determined by chip and ceramic package shell, is said in reason, as long as increase ceramics height and ceramic impeller quantity and depth,
With regard to creep age distance can be increased, so as to improve the pressure-resistant and insulaion resistance of shell, but limited by installation weight and volume, climb electricity
The increase of distance is also limited, and 6 inches of ceramic cartridge total heights applied to extra-high voltage direct-current transmission are limited at present
Within 35mm, creep age distance how in the case where not increasing installation weight and volume, increases the pressure-resistant of shell in 48mm or so
With insulating properties so as to improving the reliability of device long-play under high-voltage great-current state, it has also become the mesh tackled key problems in the industry
One of mark.
