Detailed Description

The principles and features of the present invention are described below in conjunction with the following drawings, the examples given are only intended to illustrate the present invention and are not intended to limit the scope of the present invention.

It should be noted that, unless otherwise expressly specified or limited, the terms "mounted," "connected," and "connected" are intended to be construed broadly, as if they were connected either fixedly or removably, or as integrally formed structures. To those of ordinary skill in the art, the specific meaning of such terms in this patent may be understood as appropriate.

Taking the 110kV zijin station in the valley city of xiangyang as an example, two power supply incoming lines, fen zizi line and zibai line, of the 110kV zijin station are both located on one section of bus, and the original violet protection line on the two sections of bus needs to quit operation due to the mode, so that the station has the risk of the power grid. According to the requirement of a dispatching mode, the Fenzilian cable needs to be adjusted to a two-section bus, the existing interval of the two-section bus is a main transformer interval and an original purple protector, the scheme analysis and design are needed to be carried out when the interval is adjusted to which interval, and partial primary equipment and line equipment adjustment is carried out simultaneously. And selecting the optimal scheme for adjusting the interval by analyzing the current situation of the station and comparing and selecting various schemes. Finally, a novel door-shaped framework cable platform is developed to optimize the interval adjustment scheme.

The current interval arrangement is successively purple, main transformer interval, subsection, fen purple, main transformer interval and white purple from the west, south to the east and north, and particularly refer to fig. 4.

The construction is influenced by the existing transformer substation layout and the pole and tower arrangement outside the substation, the work is difficult and heavy, and firstly, the space available in the Zijin substation is very small. Secondly, the transformer substation is put into operation for 40 years, and the framework, the tower material and the ground lead are corroded, so that a plurality of potential safety hazards exist; thirdly, the line outgoing of the line outside the station is complex, a civil house near a line corridor is subjected to a seam insertion, and any path change can involve crossing the civil house; fourthly, the power failure construction time is short, and the construction must be finished in a short time, so that the power utilization of the purple gold supply area is ensured. Fifthly, the tower position of the existing 35kV cable terminal is used up and occupies the original 110kV outgoing tower position. The normal incoming and outgoing lines of 110kV are influenced. Sixthly, after the interval adjustment is finished, the maintenance safety of personnel needs to be considered.
