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 220 kV outdoor GIS double-flying outlet layout structure is composed of four GIS outlet intervals 1 and two outlet frames. The four GIS outlet intervals 1 are connected by two horizontally arranged busbars 2, and the GIS outlet Interval arrestor built-in. The three phase wires 8, 9, and 10 of each GIS outlet interval are placed horizontally, one phase wire 8 is perpendicular to the bus bar 2, and the other two phase wires 9, 10 extend in a straight line and bend outward, so that the three outlet sleeves The tubes are arranged in a vertical line, the horizontal distance between adjacent phase lines is 0.5-0.7 meters, the distance between adjacent bushings is 3.0-3.5 meters, and the distance between the center of the outlet frame and the outlet bushing is 3.3-3.5 meters .

[0028] The outlet frame is compos...

Abstract

The invention discloses a 220kV outdoor 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 220kV GIS bus is reduced.

Description

technical field [0001] The invention relates to an arrangement structure and an outlet frame of electric equipment, in particular to a 220 kV outdoor GIS double-flying-fly 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 l...
