Abstract

The utility model discloses a kind of 35kV power distribution equipments using GIB busbares, including main transformer, step down side is connected with 35kV busbares using GIB busbares, GIB busbares(1)With potting breaker(3)End of incoming cables connects, potting breaker(3)Leading-out terminal be connected with shunt reactor;The GIB busbares are built-in with disconnecting switch(2);The reactive-load compensation of the 35kV main transformer low-pressure sides uses yi word pattern dry type air core shunt reactor;Step down side replaces conventional open style bare bus bar, GIB built-in disconnectors using GIB busbares, while uses potting breaker, that is, improves electrical equipment reliability, and reduces the probability that main transformer has a power failure, and integral layout more flexibility, saves floor occupying area.

Description

A kind of 35kV power distribution equipments using GIB busbares
Technical field
The utility model belongs to power distribution equipment technical field, is related to a kind of 35kV power distribution equipments using GIB busbares.
Background technology
Continuous with China's power grid construction scale expands, and the anxiety of land use resource, the site choosing of substation Difficulty is selected also constantly to expand.The floor space of substation is smaller, is more conducive to the addressing of substation, and has saved the soil of preciousness Ground resource.The general plan layout and size and apparatus-form of outdoor substation are closely related, and power distribution equipment uses GIS device Space can effectively be saved, be greatly reduced general layout size, low-voltage reactive power power distribution equipment floor space ratio compared with Greatly, to the appropriate type selecting of idle power distribution equipment equipment, compact arrangement requirement can be met, it is possible to reduce the occupation of land face of substation Product.
Utility model content
For problem and shortage existing for current substation's general layout, there is provided a kind of 35kV using GIB busbares matches somebody with somebody Electric installation.
The utility model uses following technical scheme:
A kind of 35kV power distribution equipments using GIB busbares, including main transformer, step down side are used with 35kV busbares GIB busbares connect, and GIB busbares 1 are connected with 3 end of incoming cables of potting breaker, and leading-out terminal and the shunt reactor of potting breaker 3 connect Connect;The GIB busbares are built-in with disconnecting switch 2.
The reactive-load compensation of the 35KV main transformer low-pressure sides uses yi word pattern dry type air core shunt reactor.
The yi word pattern dry type air core shunt reactor arrangement, it include A, B, C three-phase single-phase reactor 4 and The support insulator of each phase, three-phase reactor are arranged according to C, A, B order in line-styled, are arranged in the single-phase electricity in centre position Anti- device sets two neutral terminals, is connected respectively with being arranged in the single-phase reactor on both sides.
Using the utility model of above-mentioned technical proposal, has the following advantages:Step down side is replaced using GIB busbares Conventional open style bare bus bar, GIB built-in disconnectors, while use potting breaker, that is, electrical equipment reliability is improved, and drop The probability that low main transformer has a power failure, integral layout more flexibility, saves floor occupying area.
Brief description of the drawings
Fig. 1 is the utility model section layout drawing.
Fig. 2 is the utility model main transformer and low-pressure side power distribution equipment area floor plan.
Wherein 1 is GIB busbares, and 2 be disconnecting switch, and 3 be potting breaker, and 4 be single-phase reactor.
Embodiment
A kind of 35kV power distribution equipments using GIB busbares, including main transformer, step down side are adopted with 35kV busbares Connected with GIB busbares 1, GIB busbares 1 are connected with 3 end of incoming cables of potting breaker, the leading-out terminal of potting breaker 3 and parallel reactance Device connects;The GIB busbares are built-in with disconnecting switch 2.
The reactive-load compensation of the 35kV main transformer low-pressure sides uses yi word pattern dry type air core shunt reactor.
The yi word pattern dry type air core shunt reactor arrangement, it include A, B, C three-phase single-phase reactor 4 and The support insulator of each phase, three-phase reactor are arranged according to C, A, B order in line-styled, are arranged in the single-phase electricity in centre position Anti- device sets two neutral terminals, is connected respectively with being arranged in the single-phase reactor on both sides.
The naked mother of conventional open style is replaced using GIB busbares using technical solution step down side provided by the utility model Line, GIB built-in disconnectors, while use potting breaker, that is, electrical equipment reliability is improved, and reduce the general of main transformer power failure Rate, integral layout more flexibility, saves floor occupying area 1700 square metres.
Above-described is only the preferred embodiment of the utility model, it is noted that for those skilled in the art For, under the premise of the utility model general idea is not departed from, some changes and improvements can also be made, these should also be considered as The scope of protection of the utility model.
