Problems solved by technology

Because metal processing parts often have anti-corrosion coatings (such as galvanized, nickel-plated) in practical engineering applications, the secondary processing will destroy the original metal surface coating, rust the spring guide rod, shorten the service life, and cost the entire thyristor valve assembly more labor costs

Abstract

The invention provides a disc spring crimping measuring tool for thyristor valve strings and IGBT (insulated gate bipolar transistor) valve strings. The disc spring crimping measuring tool comprises a stress application lead screw, a jack, a support and a hydraulic source. The support comprises a bottom surface, a top surface and support rods, the bottom surface is parallel to the top surface, the support rods are vertically arranged between the bottom surface and the top surface, the jack is vertically penetratingly arranged on the top surface of the support, the stress application lead screw is vertically penetratingly arranged in the jack, and the hydraulic source is arranged at an included angle position among the bottom surface and the support rods of the support and is connected with the jack. The disc spring crimping measuring tool is characterized in that the jack is provided with a pressure sensor, and a transverse rod is arranged on the support rods and is vertically provided with a displacement sensor. Compared with the prior art, the disc spring crimping measuring tool for the thyristor valve strings and the IGBT valve strings has the advantages that matched grooves of spring guide rods can be machined by the aid of measured data of pressures and displacement of disc springs, so that each thyristor can be assembled at one step, damage to the spring guide rods can be prevented, and the work efficiency can be greatly improved.

Description

technical field [0001] The invention relates to a disc spring crimping measuring tool, in particular to a disc spring crimping measuring tool for thyristor valve strings and IGBT valve strings. Background technique [0002] The core technology of DC power transmission is concentrated in the converter station equipment. The converter station realizes the mutual energy conversion between DC and AC in the DC power transmission project. In addition to the same equipment as the AC substation in the AC field, it also has the following unique equipment: converter valve , control and protection system, converter transformer, AC filter and reactive power compensation equipment, DC filter, smoothing reactor and DC field equipment, while the converter valve is the core equipment in the converter station, and its main function is to perform AC DC conversion, from the initial mercury arc valve to the current electric control and light control thyristor valve, the unit capacity of the con...
