Existing leading-out terminal adopts a word arrangement mode setting, and the same ABC three-phase returning back out in line is positioned at sustained height, more than its spaced apart size at least remains on critical value, therefore, causes existing framework width to be at least 24m; And in the utility model, three-phase being divided into phase and a two-phase, minute high and low layer leading-out terminal output, thus, can reduce spaced apart, thereby reach the object that reduces framework width.
As a kind of improvement project of the present utility model, the inlet wire side at aforementioned main transformer lead-in wire terminal place is provided with overhead, and the outgoing line side at leading-out terminal place is provided with outlet structure, and leading-out terminal connects corresponding outgoing line side by the wire being erected on overhead, forms one across framework; Aforementioned one returns back out line across arranging two on framework, high-rise leading-out terminal comprise one return back out a phase in line, another returns back out the two-phase in line, low layer leading-out terminal comprises that one returns back out other two-phase in line and another returns back out another phase in line.A framework operated by rotary motion two returns back out line, raise the efficiency, cost-saving, when arranging, a two-phase that returns back out line is returned back out to one of line with another and be placed together mutually, no matter make high-rise leading-out terminal or low layer leading-out terminal, all keep three-phase outlet, not only as existing framework, can realize a framework two and return back out line, and reduced spaced apart simultaneously, reduced framework width.
As another kind of improvement project of the present utility model, when the lightning protection device of leading-out terminal is arranged on GIS device interior, the outside of high-rise leading-out terminal is used for drawing leading-out wire, and inner side is for connecting the high cross-line at main transformer interval.
The utility model has the advantages that: two return back out line shares one across framework, and framework width is only 18m, and each outgoing line interval is arranged in the place of an interval width, has reduced to greatest extent the floor space in place, has met the requirement of power network development.

Embodiment
Below in conjunction with accompanying drawing, the utility model of take is applied to outside 220kV room distribution, and as example, the utility model is described in further detail.
As Figure 1-3, the utility model comprises more than one power supply unit, and described power supply unit comprises main transformer lead-in wire terminal, distribution equipment and leading-out terminal; Main transformer lead-in wire terminal connects the lambda line side of equipment in the main transformer interval in distribution equipment; Equipment connection leading-out terminal in outgoing line interval in distribution equipment; In main transformer interval, equipment divides and is located at the bus left and right sides and oppositely lays in equipment and outgoing line interval; Aforementioned leading-out terminal is double-deck leading-out terminal, comprises high-rise leading-out terminal and low layer leading-out terminal; It is overhead 9 that the inlet wire side at aforementioned main transformer lead-in wire terminal place is provided with, and the outgoing line side at leading-out terminal place is provided with outlet structure 8, and leading-out terminal connects corresponding outgoing line side by the wire being erected on overhead 9, forms one across framework; Aforementioned one returns back out line across arranging two on framework, high-rise leading-out terminal comprise one return back out A phase in line, another returns back out B, C two-phase in line, low layer leading-out terminal comprises that one returns back out B in line, C two-phase and another returns back out the A phase in line.As can be seen here, high-rise occur that end and low layer leading-out terminal include ABC three-phase, the mode comparison of still arranging with traditional yi word pattern, returns back out three in line and is staggeredly set due to same, therefore, has shortened the width of framework.
For the distribution equipment that is connected to a leading-out terminal, high-rise leading-out terminal 1 and low layer leading-out terminal 2 are located at the outgoing line side of a distribution equipment; It is overhead 9 that the inlet wire side of the distribution equipment in main transformer interval is provided with, and leading-out terminal corresponding to this distribution equipment connects corresponding outgoing line side by being erected at wire 7 on overhead.
Double-deck outlet outlet on the middle and senior level is arranged a phase (or two-phase) returning back out in line by strain insulator string 5 and high-rise strain insulator string 6, and low layer outlet arranges that by low layer strain insulator string 4 this returns back out the other two-phase (or a phase) in line; The outside of high-rise outlet is used for drawing leading-out wire, and inner side is for connecting the high cross-line 7 at main transformer interval.
Described overhead 9 have three, and three overhead 9 are located on place, distribution equipment place, and wire is crossed over distribution equipment overhead.
Wire, by main transformer tubular distance piece 3, by overhead 9 leap power distribution equipment overhead, oppositely causes outlet structure 8, forms the pattern of Dual-layer outlet.During plover type outlet maintenance, only need this interval to have a power failure.Different alternate band electrical distances are greater than 5m, and band electrical distance nargin is large, less on adjacent spaces impact.
This example adopts double bus scheme, and power distribution equipment adopts circuit breaker dually arrayed pattern, adopts outdoor fully closed combined electric unit (GIS equipment).Utilize the feature of GIS apparatus arrangement, pull open the distance of high-rise outlet casing tube and bottom outlet casing tube, compressed the lateral dimension of power distribution equipment, two return back out line shares one across framework, framework width is only 18m, and in same interval, out of phase equipment forms the outlet of plover type by high-rise and the double-deck outlet structure of bottom.
The utility model has been saved framework and material, has compressed occupation of land, has saved investment, effectively raises the utilization ratio in place in transformer station simultaneously.This power distribution equipment form is not limited by the grade of voltage, for adopting the transformer station of GIS equipment, circuit breaker dually arrayed all can realize the pattern of plover type outlet.
