Document Type and Number:
WIPO Patent Application WO/2021/218963
Kind Code:
A1
Abstract:
A thyristor element, a thyristor element assembly structure and a soft starter. The thyristor element comprises a gate assembly (80) and a chip packaging assembly (60). The chip packaging assembly (60) is provided with a blind hole (608) which is at least partially and fixedly connected to the gate assembly (80). The axis of the blind hole (608) is perpendicular to a chip (604) in the chip packaging assembly (60). The gate assembly (80) comprises a gate needle (803) extending from the interior of the gate assembly (80) and abutting against a chip gate of the chip (604); and a lug plate (801) extending out of the top of the gate assembly (80) and used for connecting the gate needle (803) and a lead (20). The thyristor element assembly structure comprises a first radiator (50), a second radiator (70), and a thyristor element sandwiched between the first radiator (50) and the second radiator (70). The first radiator (50) and the second radiator (70) are connected by means of an insulating fastener (10). A disc spring group (101) of the insulating fastener (10) is sleeved outside an insulating sleeve (103) and is located between the first radiator (50) and the insulating sleeve (103).
