Abstract
本实用新型公开了一种220kV配电装置的布置结构。常规变电站的220kV侧主母线使用比较多的是管型硬母线及软导线，由于裸导线是布置于空气中，因此导线相间距离必须保证足够的安全距离，进而增加了配电装置的占地面积。本实用新型的特征在于，从GIL管型母线上分别垂直引出A、B、C三相套管，GIL管型母线的一侧设有三个处于同一直线上的隔离式断路器；所述的三个隔离式断路器与GIL管型母线平行布置，所述的三个隔离式断路器分别与GIL管型母线的A、B、C三相套管采用软导线连接。本实用新型一方面大大减少了配电装置的占地面积，另一方面提供了一种高可靠性、低故障率、维护量少的配电装置布置形式。
The utility model discloses an arrangement structure of a 220kV power distribution device. The 220kV side main busbars of conventional substations mostly use tubular hard busbars and soft wires. Since the bare wires are arranged in the air, the distance between the wires must ensure a sufficient safety distance, which increases the footprint of the power distribution device. . The utility model is characterized in that three-phase bushings A, B, and C are vertically drawn out from the GIL tubular bus, and one side of the GIL tubular bus is provided with three isolated circuit breakers on the same straight line; the three Two isolated circuit breakers are arranged in parallel with the GIL tubular busbar, and the three isolated circuit breakers are respectively connected to the A, B, and C three-phase bushings of the GIL tubular busbar with flexible wires. On the one hand, the utility model greatly reduces the occupied area of the power distribution device, and on the other hand, it provides a layout form of the power distribution device with high reliability, low failure rate and less maintenance.
Description
Technical field
The utility model relates to power system device, specifically a kind of arrangement of 220kV power distribution equipment.
Background technology
Conventional outdoor substation 220kV power distribution equipment adopts conventional outdoor equipment mostly.220kV conventional equipment quantity is many, overall dimensions large, it is wide to take up an area, and the tie point between equipment is many, causes the hidden danger point of fault many.Easily there is corrosion in the factor impacts such as equipment climate environment, shortens service life of equipment, having used a large amount of isolated switchgears in transformer station at present, need to often carry out repair and maintenance, greatly affects power supply reliability.
At the 220kV of conventional substation side main bus bar, present stage is used many have hard bus of cast and two kinds of wires of flexible conductor, the wire of these two kinds of patterns is all exposed to be arranged in air, particularly in the more serious area of some damage ratios, just need to often carry out cleaning.Because plain conductor is to be arranged in air, so wire phase spacing must guarantee enough safe distances, and then increased the floor space of power distribution equipment.
Utility model content
Technical problem to be solved in the utility model is to overcome the defect that above-mentioned prior art exists, and provides a kind of arrangement of 220kV power distribution equipment, to reduce the floor space of power distribution equipment.
For this reason, the technical solution adopted in the utility model is as follows: a kind of arrangement of 220kV power distribution equipment, comprise GIL tube type bus, it is characterized in that, from GIL tube type bus, vertically draw respectively A, B, C three-phase sleeve pipe, distance between adjacent casing is 3-4m, and a side of GIL tube type bus is provided with three isolated circuit breakers on same straight line;
Described three isolated circuit breakers and GIL tube type bus are arranged in parallel, and horizontal range is between the two 3.5-4.5m, and three described isolated circuit breakers adopt flexible conductor to be connected with A, B, the C three-phase sleeve pipe of GIL tube type bus respectively.
As the further of technique scheme improved and supplemented, the utility model is taked following technical measures:
Described GIL tube type bus is erected on a plurality of erection columns.
Distance between adjacent casing most preferably is 3.5m.
Described isolated circuit breaker and the horizontal range between GIL tube type bus most preferably are 4m.
The beneficial effect the utlity model has is as follows: greatly reduced on the one hand the floor space of power distribution equipment, a kind of high reliability, less trouble, power distribution equipment arrangement form that maintenance is few are provided on the other hand.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
Fig. 2 is the end view of Fig. 1.
Fig. 3 is floor plan of the present utility model.
In figure, 1-GIL tube type bus, 2-A phase sleeve pipe, 3-B phase sleeve pipe, 4-C phase sleeve pipe, the isolated circuit breaker of 5,6,7-, 8-erection column.
Embodiment
Below in conjunction with specification drawings and specific embodiments, the utility model is described in further detail.
The arrangement of 220kV power distribution equipment as shown in the figure, from GIL tube type bus 1, vertically draw respectively A, B, C three-phase sleeve pipe 2,3,4, distance between adjacent casing is 3-4m, and a side of GIL tube type bus 1 is provided with three isolated circuit breakers 5,6,7 on same straight line; Described three isolated circuit breakers and GIL tube type bus are arranged in parallel, and horizontal range is between the two 3.5-4.5m, and three described isolated circuit breakers adopt flexible conductor to be connected with A, B, the C three-phase sleeve pipe of GIL tube type bus respectively.Described GIL tube type bus 1 is erected on a plurality of erection columns 8.
Below only with regard to the utility model preferred embodiment, be described, but can not be interpreted as it is limitations on claims.The utility model is not only confined to above embodiment, and its concrete structure allows to change.All various variations of doing in the protection range of the utility model independent claims are all in protection range of the present utility model.
