The purpose of this utility model is that being directed to above-mentioned the problems of the prior art, a kind of 750kV GIS breaker is provided
Installation and maintenance access is arranged among two column GIS breakers, using across the road GIL pipeline bus in ground in double-row type arragement construction
Breaker is connect with two column main bus-bars, reduces main bus-bar length, installation, maintenance are convenient, reduce project cost, operation can
It leans on.
To achieve the goals above, the technical solution adopted in the utility model are as follows:
Installation and maintenance access is arranged in GIS breaker including two column arrangements, the intermediate of two column GIS breakers, and two column GIS are disconnected
It is respectively arranged a component branch bus on the outside of the device of road, one group of outlet structure, two column GIS are respectively arranged on the outside of two component branch bus
Breaker is connected from different buses by across road GIL pipeline bus on the ground.
The two component branch bus are I branch bar of 750kV outlet and II branch bar of 750kV outlet, ground overpass
A column GIS breaker can be set again on the route of road GIL pipeline bus connection I branch bar of 750kV outlet.
The outlet structure includes that the outlet casing tube, voltage transformer and outlet being successively connected outward with main bus-bar are taken shelter from the thunder
Device.
Outlet casing tube, voltage transformer and the outlet arrester is installed by electric power pylon.
The two column GIS breakers are separately connected 750kV three-phase bus, GIS breaker, two component branch bus, ground
Across road GIL pipeline bus, outlet casing tube, voltage transformer and outlet arrester are all made of 750kV voltage class.
The installation and maintenance access arranges the lower section of across road GIL pipeline bus on the ground, and installation and maintenance access can lead to
Cross crane.
Compared with prior art, the utility model has following the utility model has the advantages that reducing the lateral length of main bus-bar,
750kV GIS main bus-bar cost is higher, and about 20,000 yuan/single-phase rice, a complete string saves bus about 65m, saving construction cost 130
Wan Yuan.Long-distance pipe bus is overcome because of the failure problems such as frequent gas leakage caused by unevenness of expanding with heat and contract with cold, usually maintenance is primary main
Interruption cost caused by bus is about 12,000,000 yuan.The lateral dimension of power distribution equipment is smaller, can be good at and main transformer pressure
Device and other power distribution equipment cooperations, reduce lateral dimension 35%.Installation and maintenance access is arranged among two column breakers,
Crane can drive directly into the channel, without turn, can directly lift by crane breaker, and crane tonnage is small, not need across bus,
Lifting is convenient, has saved a large amount of installation and repairing times, after tested, can save installation, repair time 25%.The utility model is first
It is secondary that reference is provided for successive projects using across the road scheme in GIL pipeline bus ground, it is reliable for operation, there is long-range popularization
Meaning.

Specific embodiment
The following describes the utility model in further detail with reference to the accompanying drawings.
Referring to Fig. 1-3, the utility model passes through breaker apparatus arrangement side in optimization routine 750kV GIS power distribution equipment
Formula reduces construction investment, reduces occupied area, eliminates the hidden trouble, ensure that the operation of electricity net safety stable.
The utility model includes the GIS breaker 1 of two column arrangements in structure, and two column GIS breakers 1 are separately connected
Installation and maintenance access, two column GIS breakers 1 are arranged in 750kV bus I 2 and 750kV bus II 3, the intermediate of two column GIS breakers 1
Outside be respectively arranged I branch bar 5 of 750kV outlet and II branch bar 6 of 750kV outlet, the outside point of two component branch bus
Do not arrange one group of outlet structure, outlet structure include the outlet casing tube 9 being successively connected outward with main bus-bar, voltage transformer 7 and
Outlet arrester 8.GIS breaker 1, two component branch bus, on the ground across road GIL pipeline bus 4, outlet casing tube 9, mutual induction of voltage
Device 7 and outlet arrester 8 are all made of 750kV voltage class.Two column GIS breakers 1 pass through from different buses on the ground across road
GIL pipeline bus 4 connects.Installation and maintenance access arranges the lower section of across road GIL pipeline bus 4 on the ground, installation and maintenance access
Crane can be passed through.Power distribution equipment lateral dimension is smaller, can be very good with main transformer and other power distribution equipment area cooperations, hang
