7 degree of fortification intensity of shake, its method particularly includes: in terms of interval width, for #1 inlet wire interval, #2 inlet wire interval, using level
The conventional gw4 type double-column horizontal open-type of replacement that is applied in combination of telescopic disconnecting switch and vertical-telescopic disconnecting switch is kept apart
Close；For #2 main transformer inlet wire interval, #1 main transformer inlet wire and i section pt interval, #3 main transformer inlet wire and iii section pt interval, using level
Telescopic disconnecting switch；For i, ii section bridge interval, ii, the disconnecting switch at iii section bridge interval adopt vertical-telescopic every
Leave pass；For i, ii section bridge interval, ii, iii section bridge interval, #2 main transformer inlet wire interval, add in the middle of bus downlead
Dress support insulator is to suppress wire windage yaw.At longitudinally spaced aspect, respectively it is spaced using the side increasing arrester or disconnecting switch
Method reducing longitudinal size, can also adopt gw17 horizontal retractable disconnecting switch using line side disconnecting switch, bus bar side every
Leave pass to reduce longitudinal size using gw16 vertical-telescopic disconnecting switch.
In sum, the present invention following advantage compared to existing technology:
The present invention 1) establish a kind of outdoor soft bus improved half-high distribution switchgear collocation method of new 110kv；2)
This kind of new distribution installation method had both remained the advantage that outdoor soft busbar distribution plant investment is saved, and further saves and accounts for
Ground area.More conventional outdoor soft bus improved half-high distribution switchgear, has saved 23.6% floor space.
