Abstract

The invention discloses a thyristor valve block of a static var compensator (SVC), which comprises one group or more than one group of mutually-tandem anti-parallel thyristor unit modules, resistance-capacitance protection unit modules, plate unit modules, frames and insulators, wherein the anti-parallel thyristor unit modules, the resistance-capacitance protection unit modules and the plate unitmodules are fixed on the frames; each resistance-capacitance protection unit module comprises a capacitor and a resistor; the insulators are fixed on the frames; the insulators are used for supporting and fixing the frame of the thyristor valve block; and each anti-parallel thyristor unit module comprises a thyristor and a profile self-heat dissipation structure, wherein the thyristor and the profile self-heat dissipation structure are pressed and combined together, and the heat dissipation of the thyristor is realized by heat conduction and convection. The thyristor valve block described by the implementation mode in the invention has the advantages of small volume, simple structure assembly and few hidden troubles and is easy to detect and maintain, the valve block can determine the tandem quantity according to the actual capacity conditions of users, and the self-heat dissipation mode is especially suitable for the SVC with medium or small capacity.

Description

technical field [0001] The invention relates to a thyristor valve group, in particular to a static var compensator (SVC, Static Var Compensator) thyristor valve group which is applied in the field of high-power semiconductor power electronics and uses profile heat dissipation. The invention can be widely used in Electric railway, electrolytic aluminum, coal mine, port, electric arc furnace and other related industries. Background technique [0002] Static Var Compensator (SVC) is a fast, smooth and controllable dynamic reactive power compensation device without rotating parts. It uses thyristor-controlled reactors and power capacitors (fixed or group switching) in parallel. Capacitors can emit reactive power (capacitive), and controllable reactors can absorb reactive power (inductive). By adjusting the reactor, the whole device can smoothly change from emitting reactive power to absorbing reactive power (or reverse), and the response is fast. The static var compensator (S...
