Abstract
Disclosed is a transformer wire inlet method under a 110KV enlarged inner bridge wiring mode. A bus in a primary transformer inlet wire internal architecture is parallel to a wire outlet direction; isolation switches whose two-side inner bridge intervals are close to one side of a primary transformer are arranged in the primary transformer inlet wire internal architecture and are arranged at an interval of 3 meters by taking a primary transformer inlet wire internal B-phase bus as a center, and then the isolation switches are directly connected with a bus above through wiring terminals; joint architectures of two-side outlet wires, side transformers and voltage transformer intervals are shifted to somewhere right above isolation switches whose two-side inner bridge intervals are away from one side of the primary transformer, and at the same time, the heights of the jointed architectures are decreased to 10 meters from 11 meters; and C-phase pillar insulators in primary transformer and side transformer inlet wire intervals are cancelled. According to the invention, the transverse widths of the primary transformer inlet wire intervals are reduced to 18 meters from 29 meters in the prior art, the transverse land occupation width of a whole distribution apparatus area is reduced to 52 meters from conventional 63 meters, the steel amount consumed by the architecture of a distribution apparatus is generally reduced by about 1.6 tons, and the land occupation area of the distribution apparatus is reduced by 17.5%.
Description
Technical field:
The present invention relates to transformer station's technical field, particularly relate to soft female semi-long type power distribution equipment 2 line 3 of a kind of 110 kv substations and become the transformer inlet wire method expanding interior bridge.
Background technology:
The arrangement of high voltage distribution installation is directly connected to other electrical equipment of whole transformer station and the layout of auxiliary equipment and the overall general layout at full station, and full station floor space is played conclusive effect.Therefore, build under the guidance of theory in current " resources conservation " and " environmental friendliness " type, nervous along with land used, especially urban land resource is rare, the environment of an inch of land is an inch of gold, seeks a kind of power distribution equipment arrangement taking up an area little, economical rationality and has become Substation Design field focus of attention problem to be effectively compressed transformer station and take up an area, to reduce resource occupation.
The power distribution equipment of expanded inter-bridge connection is become for soft female semi-long type 2 line 3 in 110 kilovolts of open airs of 110 kv substation, to compress power distribution equipment lateral arrangement a size of target to greatest extent, as a example by certain 110KV open air AIS transformer station (seeing Fig. 1-3), in its 110 KV distribution devices arranged, bridge and main transformer inlet wire interval transverse width are 29 meters, it is 63 meters that width is laterally taken up an area in whole power distribution equipment district, and it is provided with C phase post insulator in main transformer inlet wire interval, this system not only rolled steel dosage is big, and floor space is big, leverages this systematic difference.
Summary of the invention:
It is an object of the invention to provide a kind of transformer inlet wire method under 110KV expanded inter-bridge connection mode, it is spaced the relative position between the disconnecting switch of main transformer side and the connected mode etc. with main bus-bar by bridge in changing both sides, not only greatly reduce steel consumption, and greatly reduce the floor space in power distribution equipment district.
In order to solve problem present in background technology, by the following technical solutions, step is as follows for the present invention:
One, by parallel with outlet direction for bus in the framework of main transformer inlet wire interval；
Two, the bridge interval disconnecting switch near main transformer side in both sides is arranged at main transformer inlet wire to be spaced in framework, centered by the B phase bus of main transformer inlet wire interval, by spacing 3 meters layout, is then directly connected with top bus by binding post；
Three, the combined frame work of both sides outlet and side transformer, voltage transformer interval is moved to both sides Nei Qiao respectively be spaced away from, directly over the disconnecting switch of main transformer side, by 11 meters, combined frame work height being down to 10 meters simultaneously；
Four, C phase post insulator in main transformer, side transformer inlet wire interval is cancelled.
Main transformer inlet wire interval transverse width is compressed to 18 meters by the 29 of prior art meters by the present invention, width is laterally taken up an area by original 63 meters of boil down tos 52 meters in whole power distribution equipment district, additionally, combined frame work height is down to 10 meters from 11 meters, the overall power distribution equipment framework rolled steel dosage about 1.6 tons that reduces, minimizing power distribution equipment district covers an area of 17.5%.

Detailed description of the invention:
With reference to Fig. 4-6, the step that prior art is improved by the inventive method is as follows:
One, first bus in main transformer inlet wire interval framework 1 in prior art is arranged vertically with outlet direction and changes into being arranged in parallel with outlet direction.
Two, then bridge in both sides is spaced the disconnecting switch near main transformer side by moving to inside framework outside the framework 1 of inlet wire interval, the disconnecting switch 2 that i.e. will be close to main transformer side is arranged in the framework 1 of main transformer inlet wire interval, again centered by the B phase bus of main transformer inlet wire interval, by spacing 3 meters layout, then being directly connected with top bus by binding post, in two, in bridge interval, equipment arranges relative invariant position.
Three, the combined frame work 3 of both sides outlet and side transformer, voltage transformer interval is moved to both sides Nei Qiao respectively and be spaced away from directly over main transformer side disconnecting switch 2, combined frame work 3 height is down to 10 meters by 11 meters simultaneously,, in both sides, in bridge interval, equipment arranges relative invariant position.
Four, C phase post insulator in main transformer, side transformer inlet wire interval is cancelled.
Bridge interval inside conductor and electrical equipment safety net distance (A1, A2, B1, C) in terminal check main transformer inlet wire and both sides, verify side transformer and voltage transformer interval and outgoing line interval inside conductor and electrical equipment safety net distance value (A1, A2, B1, C).
The present invention by change the relative position between the disconnecting switch of main transformer side, bridge interval in both sides and and the connected mode of main bus-bar and both sides in bridge interval near voltage transformer side disconnecting switch relative to outlet and side transformer, the relative position of voltage transformer interval combined frame work, bridge in 110 KV distribution devices and main transformer inlet wire are spaced transverse width and are compressed to 18 meters by the 29 of prior art meters, width is laterally taken up an area by original 63 meters of boil down tos 52 meters in whole power distribution equipment district, additionally, combined frame work height is down to 10 meters from 11 meters, overall minimizing power distribution equipment framework rolled steel dosage about 1.6 tons, reduce power distribution equipment district and cover an area of 17.5%.
