Abstract

The invention is a level pressure mechanism for series thyristor valve group, relating to the installing mechanism of thyristor valve, composing an outer frame by three fore bearing epoxy board and head-end flange and rear-end flange; on the side of the head-end flange, a pressure spring guide rod is jacketed with a disc spring; there is a disc spring protection piece arranged at the head end of the disc spring; there is a flow guide copper network and transition regulating circular aluminum arranged at the other end of the disc spring; on the side of the rear-end flange, a guide sleeve is connected with the rear-end flange; the guide sleeve is jacketed in order with transition regulating circular aluminum, the flow guide copper network, and a push guide rod from the head end to the rear end; there is a hexagonal bolt arranged on the outmost side of the rear-end flange; there are groups of water cooling radiators and thyristors alternatively connected in series between the head-end and rear-end transition regulating circular alumina. The invention can assure the force the thyristor valve group bears is uniform and the mechanical stability is excellent.

Description

technical field [0001] The invention relates to an installation structure of a thyristor valve, a core device of a static var compensator (SVC) in a power system and power electronics technology, in particular to a constant pressure mechanism of a series thyristor valve group. Background technique [0002] The thyristor valve is the core component of the static var compensator. When the thyristor valve group is working, it must ensure that it has good mechanical stability. In addition, the thyristor generates heat due to its own power consumption during operation. If appropriate measures are not taken to dissipate this heat, the temperature of the PN junction of the module die will rise sharply, resulting in deterioration of device characteristics, until it is completely damaged. [0003] In order to make the thyristor fully exert its rated performance and improve the reliability in use, it is necessary to select the radiator scientifically and install it correctly. Only b...
