Abstract
The invention discloses an arrangement structure of a 220 kV distribution apparatus. A 220 kV side main bus of a conventional transformer station employs a tubular hard bus or a soft conductor more often, and since a bare conductor is arranged in air, it must be guaranteed that a sufficient safety distance is reserved for the distances among the phases of the conductor, thus the land occupation area of the distribution apparatus is increased. The arrangement structure is characterized in that an A-phase sleeve, a B-phase sleeve and a C-phase sleeve are respectively vertically led out from a GIL tubular bus, and one side of the GIL tubular bus is provided with three isolated type circuit breakers disposed at the same line; and the three isolated type circuit breakers are in parallel arrangement with the GIL tubular bus, and the three isolated type circuit breakers are respectively connected with the A-phase sleeve, the B-phase sleeve and the C-phase sleeve of the GIL tubular bus by use of soft conductors. The arrangement structure provided by the invention, on one hand, greatly reduces the land occupation area of the distribution apparatus, and on the other hand, provides a distribution apparatus arrangement form which is high in reliability, low in fault rate and small in maintenance amount.
Description
Technical field
The present invention 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.
Summary of the invention
Technical problem to be solved by this invention 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 used in the present invention 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 present invention takes 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 that the present invention 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 invention.
Fig. 2 is the end view of Fig. 1.
Fig. 3 is floor plan of the present invention.
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 invention will be further described.
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 just preferred embodiment of the present invention is described, but can not be interpreted as it is limitations on claims.The present invention is not only confined to above embodiment, and its concrete structure allows to change.All various variations of doing in the protection range of independent claims of the present invention are all in protection scope of the present invention.
