Title: IMPROVED HIGH-POWER THYRISTOR
Abstract:
A high-power thyristor. The thyristor comprises a thyristor base (1), a ceramic circular shell, a protective layer (2), a chip (3) and a thyristor cover (4) which are arranged in sequence in an axial direction, wherein a rubber sleeve is wrapped around the outer edge of the chip (3); the protective layer (2) and the chip (3) are buckled into the ceramic circular shell in sequence; and a temperature sensor is arranged in the axial direction of the thyristor. By additionally installing a precise temperature sensor on the chip of the thyristor, the real-time monitoring of the temperature of the chip of the thyristor is realized, and the temperature measurement deviation can be reduced, forming intuitive real-time temperature data, and providing reliable conditions for junction temperature protection and other intellectualized functions of a direct-current converter valve.
