Description
Technical field
The invention belongs to power transmission and transformation fields, and in particular to a kind of ehv power transmission GIS breaker double-row type arragement construction.
Background technique
With the fast development of power grid construction, the scale of Ultra-high Voltage Substations engineering is increasing, and the Northwest is due to solid
The special natural environmental conditions such as some height above sea levels, the temperature difference are big, ultraviolet light is strong, using ordinary distribution device arrangement it is insufficient increasingly
It is prominent.Land reserved resources wretched insufficiency, the Frequent Troubles influenced in substation operation by particular surroundings improve land resource benefit
It is the project that power grid construction must face with rate, reduction project cost, guarantee substation operation safety etc..With regard to 750kV substation
Power distribution equipment design for, 750kV GIS breaker is one of common equipment of 750kV power distribution equipment, conventional arrangement side
Formula is "-" type, although as general one of design scheme, in extensive substation, because it takes up a large area, engineering
Frequent Troubles affected by environment after cost is high, equipment investment is run, influence the safe and stable operation of power grid.
Summary of the invention
It is an object of the invention to be directed to above-mentioned the problems of the prior art, a kind of ehv power transmission GIS open circuit is provided
Installation and maintenance access is arranged among two column GIS breakers in device double-row type arragement construction, female using across the road GIL pipeline in ground
Breaker is connect by line with two column main bus-bars, reduces main bus-bar length, and installation, maintenance are convenient, reduce project cost, run
Reliably.
To achieve the goals above, the technical solution adopted by the present invention 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 present invention is with 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, and 1,300,000 yuan of saving construction cost.Gram
Long-distance pipe bus has been taken because of the failure problems such as frequent gas leakage caused by unevenness of expanding with heat and contract with cold, a main bus-bar has usually been overhauled and causes
Interruption cost be about 12,000,000 yuan.The lateral dimension of power distribution equipment is smaller, can be good at main transformer and other
Power distribution equipment cooperation reduces lateral dimension 35%.Installation and maintenance access is arranged among two column breakers, and crane can
The channel is driven directly into, without turning round, can directly lift by crane breaker, crane tonnage is small, does not need across bus, lifting side
Just, a large amount of installation and repairing times have been saved, after tested, installation, repair time 25% can have been saved.The present invention uses GIL for the first time
Across the road scheme in pipeline bus ground, provides reference for successive projects, reliable for operation, has long-range dissemination.

Specific embodiment
Present invention will be described in further detail below with reference to the accompanying drawings.
Referring to Fig. 1-3, the present invention passes through breaker apparatus arrangement in optimization routine 750kV GIS power distribution equipment, drop
Low construction investment reduces occupied area, eliminates the hidden trouble, ensure that the operation of electricity net safety stable.
The present invention includes the GIS breaker 1 of two column arrangements in structure, and two column GIS breakers 1 are separately connected 750kV mother
Installation and maintenance access, the outside of two column GIS breakers 1 is arranged in line I 2 and 750kV bus II 3, the intermediate of two column GIS breakers 1
It is respectively arranged I branch bar 5 of 750kV outlet and II branch bar 6 of 750kV outlet, is respectively arranged on the outside of two component branch bus
One group of outlet structure, outlet structure include that the outlet casing tube 9, voltage transformer 7 and outlet being successively connected outward with main bus-bar are kept away
Thunder device 8.GIS breaker 1, two component branch bus, on the ground across road GIL pipeline bus 4, outlet casing tube 9,7 and of voltage transformer
Outlet arrester 8 is all made of 750kV voltage class.Two column GIS breakers 1 are managed from different buses by across road GIL on the ground
Road bus 4 connects.Installation and maintenance access arranges the lower section of across road GIL pipeline bus 4 on the ground, and installation and maintenance access can lead to
Cross crane.Power distribution equipment lateral dimension is smaller, can be very good with main transformer and other power distribution equipment area cooperations, crane can be straight
It connects and drives into the channel, without turning round, that is, be convenient to the GIS devices such as installation and repairing breaker.
Installation and maintenance access of the present invention is arranged among two column breakers, and small tonnage crane may be selected and can directly lift by crane two
Side breaker avoids the conventional medium-and-large-sized crane of "-" type scheme and repeatedly moves backward that turn to bring inconvenient, is more advantageous to installation inspection
It repairs, reduces GIS breaker installation period, and reduce project cost；GIL pipeline bus across road scheme on the ground is used for the first time,
Convenient for observation, maintenance, maintenance.The present invention reduces 750kV main bus-bar lateral lengths, and it is too long to solve Special environment bus
It expands with heat and contract with cold frequent principal fault problem caused by unevenness；It can be avoided the conventional medium-and-large-sized crane of "-" type scheme and repeatedly move backward and turn
To bring inconvenience, it is more advantageous to installation and repairing, reduces GIS breaker installation period, and reduce project cost.
The present invention can effectively solve the Northwest due to height above sea level, the temperature difference is big, ultraviolet light is strong etc., and special environment conditions cause
Long-distance pipe bus saves land occupation and investment because of failure problems such as gas leakage frequent caused by expanding with heat and contract with cold, and application prospect is considerable.
