Abstract

The invention provides a thyristor assembly, a thyristor press-fit structure and a direct current transmission converter valve. The thyristor assembly comprises a plurality of thyristors, a pluralityof damping resistors and a plurality of radiators; the thyristors and the radiators are alternately arrayed, and the thyristors mutually fit the adjacent radiators; grooves are formed in the radiators, and the damping resistors are disposed in the grooves to fit the radiators. According to the thyristor assembly, the thyristor press-fit structure and the direct current transmission converter valve, effective heat dissipation of the thyristors and the damping resistors can be ensured.

Description

technical field [0001] The invention relates to the technical field of direct current transmission, in particular to a thyristor component, a thyristor pressing structure and a direct current transmission converter valve. Background technique [0002] Thyristors and damping resistors are the core components of UHVDC transmission. The heat dissipation performance of thyristors and damping resistors is one of the key factors for the reliable operation of converter valves. Therefore, it is particularly important to ensure the heat dissipation performance of thyristors and damping resistors. [0003] At present, there are mainly three types of thyristor press-fitting mechanisms, which are: belt structure, plate structure, and rod structure. Among them, the drawstring adopts a ring structure, and its structural strength is difficult to meet the requirements of the thyristor press-fitting force. Therefore, there are certain risks in engineering applications. The drawstring structu...
