Abstract

The invention discloses an installation climbing piece for a direct-current supporting capacitor. The installation climbing piece is mainly composed of an installation climbing plate member, a first welding nut and a second welding nut, wherein the installation climbing plate member comprises an installation climbing plate member body, first installation holes and second installation holes, the installation climbing plate member body is an integrated structure, the first installation holes are arranged on the surface of the installation climbing plate member body, the second installation holesare formed in the two small side faces of the installation climbing plate member body, first welding nuts are welded to the inner walls of the reverse sides of the first installation holes of the installation climbing plate member, and second welding nuts are welded to the inner walls of the reverse sides of the second installation holes of the installation climbing plate member. The installationclimbing piece is simple in structure and convenient to operate, and can meet the operation requirements of the direct-current supporting capacitor during production, installation, transportation andmaintenance.

Description

technical field [0001] The invention belongs to the field of capacitor structures, and in particular relates to a mounting board for DC support capacitors. Background technique [0002] The DC support capacitor is a key component of the converter, which plays the role of stabilizing voltage and filtering on the DC side of the converter. At present, high-voltage and large-capacity DC supports are required in high-power converters such as tens of megawatt-class high-voltage converters, high-speed train converters, high-power STATCOMs, and DC capacitors for flexible DC transmission projects. capacitor. [0003] In recent years, these DC support capacitors have gradually adopted a dry structure. The common features of this type of capacitor are high voltage, large capacity, and heavy weight. The largest DC support capacitor reaches 210kg. In the process of manufacturing, transportation, installation, and maintenance of this type of capacitor, the installation of one of the me...
