Embodiment Construction

[0026] The present invention will be further described below in conjunction with the accompanying drawings and specific embodiments.

[0027] Such as Figure 2-7 The shown 110 kV outdoor GIS double-flying outlet arrangement structure is composed of four GIS outlet intervals 1 and two outlet frames. The four GIS outlet intervals 1 are connected by a horizontally arranged bus bar 2 . The lightning arrester 10 of the GIS outgoing line interval is externally suspended on the outgoing line cross arm, and the phase line 8 in the GIS outgoing line interval is perpendicular to the bus bar 2 . The vertical outlet bushing part 7 is made up of a base 71 and three branch sleeves 72, 73, 74. The bottoms of the three branch sleeves are installed on the base and distributed radially. The inner chambers of the three branch sleeves are respectively connected to the The inner cavity of the seat body communicates, and the three branch sleeves are arranged in a vertical line (that is, the instal...

Abstract

The invention discloses a 110kV GIS double-dragonfly-type outlet wire arrangement structure. Although a GIS is adopted, the size of a total wire outlet side of a transformer substation is not reduced because of the width limitation of an outlet wire door frame of a conventional outdoor GIS. The technical scheme provided by the invention is characterized in that a wire outlet structure includes a vertical steel pipe pole and six wire outlet cross arms formed on the steel pipe pole. The wire outlet cross arms are all perpendicular to the steel pipe pole. The six wire outlet cross arms are distributed in three layers including an upper layer, a middle layer and a lower layer. Each of the layers is composed of two of the wire outlet cross arms disposed on two sides of the steel pipe pole respectively and the wire outlet cross arms in each layer are arranged in a staggered manner with the wire outlet cross arms on the same side and in the other layers. Double-loop vertical overhead wire outlet arrangement in the upper layer, the middle layer and the lower layer is formed through the cooperatively use of two GIS wire outlet intervals and the wire outlet structure. According to the invention, the wire outlet structure of the outdoor GIS power distribution device is simplified, the transverse size is reduced, floor space occupancy can be reduced distinctively and length of a 110kV GIS bus is reduced.

Description

technical field [0001] The invention relates to the arrangement structure and framework of electric equipment, in particular to a 110 kV outdoor GIS double-flying outlet arrangement structure. Background technique [0002] With the development of the power grid, the number of substations is increasing, the land reserve resources are seriously insufficient, and the cost of land acquisition and demolition is increasing day by day. Especially in some urban center areas, the cost of land acquisition is on the rise, and the selection of substation sites is becoming more and more difficult. Land saving in substations is an urgent problem to be solved at present. [0003] At present, GIS equipment is a kind of intensive power equipment, which has improved the shortcomings of conventional equipment layout, such as scattered large area, high failure rate, heavy installation, debugging and equipment maintenance, and long construction period. It has the advantages of compact layout, fr...
