Medium-voltage side hybrid gas insulated switchgear (HGIS) distribution device for ultrahigh voltage intelligent substation

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
