Abstract

The invention relates to a thyristor converter valve large component silicon stack structure comprising an outer frame and multiple heat radiators and thyristors which are installed in parallel insidethe outer frame. The outer frame comprises a pair of insulating pull plates which are vertically arranged and a pressing side installing block and a disc spring side installing block which are arranged on the two ends between the two insulating pull plates. Two parallel limiting bolts are arranged side by side on the outer side of the pressing side installing block, and a pressing side bus bar isarranged on the inner side. A disc spring assembly is arranged on the inner side of the disc spring side installing block. A disc spring side bus bar is arranged on the inner side of the disc springassembly. The thyristors are connected in series between two adjacent heat radiators and coaxial with the heat radiators. The same ends of the two adjacent heat radiators are connected in series by awater pipe, and the other end of each heat radiator is respectively connected in parallel with the water inlet pipe and the water outlet pipe. Double helical heat radiation channels are arranged inside the heat radiators. The thyristor converter valve large component silicon stack structure has a simple and compact structure and can avoid bending deformation of the silicon stack under the action of high temperature circulation and has the effect of heat radiation of series and parallel waterways.

Description

technical field [0001] The invention belongs to the technical field of thyristor converter valves, and in particular relates to a silicon stack structure of a large component of a thyristor converter valve. Background technique [0002] In the power system, the converter valve is a very important DC transmission equipment, and the thyristor is the core component of the equipment. In the converter valve, several thyristors and thyristor radiators are pressed together by great pressure to form a silicon stack assembly. As a key component of the converter valve, the structure and press-fit quality of the silicon stack component play a vital role in the safe and stable operation of the converter valve. [0003] Existing silicon stack components are mainly divided into two structures. The first structure uses two front and rear epoxy resin plates and the left and right end plates to form a frame, uses springs to suspend the radiator on both sides of the epoxy resin plates, and ...
