Abstract

The invention discloses a medium-voltage side distribution device for an ultrahigh voltage intelligent substation by employing HGIS equipment. The medium-voltage side distribution device mainly comprises HGIS equipment compact type double-row back-to-back arrangement; the distribution device is formed by a combined framework and a large-span bus beam framework; road optimization arrangement is formed in the field of the distribution device; and a wire outlet bent frame, a wire inlet bent frame and a bus beam are designed into an integrated combined framework by employing the dual-bus or dual-bus sectioned wiring type HGIS distribution device. The distribution device has the characteristics of reducing the floor area of a substation, particularly an intelligent substation, saving the steel amount and reducing the total engineering investment, is suitable for engineering design and construction of the ultrahigh voltage intelligent substation, and is particularly suitable for the medium-voltage side by employing the design of the dual-bus or dual-bus sectioned wiring type ultrahigh voltage intelligent substation.

Description

technical field [0001] The invention relates to a power distribution device using HGIS equipment on the medium voltage side of an ultra-high voltage substation, which is suitable for the design of an ultra-high voltage intelligent substation, especially suitable for an ultra-high voltage intelligent substation with double busbars or double busbar segmented connection type on the medium voltage side Design; belongs to the technical field of power transmission and transformation engineering design. Background technique [0002] The smart substation is based on the digital substation. By adopting advanced sensor, electronics, information, communication, control, intelligent analysis software and other technologies, a digital unified application platform for all information collection, transmission, analysis and processing of the whole station is established to realize the digitalization of the substation. Advanced application functions such as automatic operation control, equip...
