Abstract
The utility model relates to the technical field of GIS, specifically to a one-tank 110kV GIS comprising a circuit breaker, two current transformers, a disconnecting switch, two three-position switches and two buses. The current transformers are arranged on the two sides of the circuit breaker; the two buses are in transverse arrangement, namely the two buses are arranged in the same horizontal direction; the upper portion of one bus is connected with the disconnecting switch and the upper portion of the other bus is connected with one three-position switch which is connected with the disconnecting switch; and the other side of the disconnecting switch is connected with the current transformer on the right side of the circuit breaker. The one-tank 110kV GIS has the advantages of reasonable layout, compact structure, convenient assembly and low cost.
Description
Technical field
The utility model relates to a kind of combined electrical apparatus technical field, specifically a kind of case 110kVGIS combined electrical apparatus altogether.
Background technology
GIS combined electrical apparatus is the abbreviation of gas-insulating and fully-enclosed combined electrical apparatus, case 110kVGIS is a kind of common combinations electrical equipment altogether, this combined electrical apparatus is generally double bus scheme, current transformer is distributed in circuit breaker both sides, traditional double-bus is arranged up and down, a bus is connected with isolating switch, another bus is connected with three-station, in this structure, isolating switch and three-station can not be pooled in an interface, must three-station and isolating switch be pooled to after same interface with the interface of current transformer fetching realization again by two threeways are set, see Fig. 1, this structure not only gap length increases, the floor space in power station is larger, and owing to having increased by two threeways, see the label 6 in Fig. 1, improved cost, interface in this structure is more, not only easily leaks air, and has also increased installation time, has also increased the transport difficulty of equipment.
Summary of the invention
The utility model provides a kind of rationally distributed in order to overcome above-mentioned defect, and compact conformation is convenient for assembly, the common case 110kVGIS combined electrical apparatus that cost is low.
The technical solution adopted in the utility model is: a kind of case 110kVGIS combined electrical apparatus altogether, comprise circuit breaker, current transformer, isolating switch, three-station and bus, three-station, current transformer and bus are two, current transformer is separately positioned on circuit breaker both sides, the current transformer that is arranged on circuit breaker left side is connected with high speed grounding switch with outlet casing tube by a three-station, it is characterized in that: two described buses are transverse arrangement of turbo, i.e. spread configuration in same level direction, a bus top is connected with isolating switch, another bus top is connected with another three-station, this three-station is connected with isolating switch, the opposite side of isolating switch is connected with the current transformer of right of circuit breaker.
The utility model is by two bus horizontal direction spread configurations, a bus top arranges isolating switch, another bus top arranges three-station, this three-station is connected with current transformer by isolating switch again, the interface of such two buses is just pooled in isolating switch, recycling isolating switch docks with current transformer, having saved two threeways but still realizes bus and is connected with the conduction of interval equipment respectively, improvement due to each component layouts of the utility model, make Power station structure compacter, two threeways have also been saved, not only reduced cost, reduced the floor space in power station, simplified assembly manipulation, improve efficiency of assembling, also reduced interface simultaneously, reduced equipment leak rate.
Accompanying drawing explanation
Fig. 1 is the structural representation before improving.
Fig. 2 is structural representation of the present utility model.
Embodiment
Now by reference to the accompanying drawings the utility model is further described, Fig. 2 is a kind of embodiment of the present utility model, comprise circuit breaker 2, current transformer 3, isolating switch 4, three-station 6 and bus 1, three-station 6, current transformer 3 and bus 1 are two, current transformer 3 is separately positioned on circuit breaker 2 both sides, and the current transformer 3 that is arranged on circuit breaker 2 left sides is connected with high speed grounding switch with outlet casing tube by a three-station 6.In the utility model, described two buses 1 are transverse arrangement of turbo, i.e. spread configuration in same level direction.Bus 1 top is connected with isolating switch 4, and another bus 1 top is connected with another three-station 6, and this three-station 6 is connected with isolating switch 4, and the opposite side of isolating switch 4 is connected with the current transformer 3 on circuit breaker 2 right sides.
The housing of traditional isolating switch 4 is generally three way type housing, in the utility model, in order to facilitate isolating switch 4 to be connected with the bus 1 of its underpart, conventionally by isolating switch 4, to the pipeline of downward-extension, be that the downward notch portion height dimension that pulls out strengthens, and be connected with the conductor of bus 1 by the conductor of isolating switch 4 inside.Equally, the housing of traditional three-station 6 is also three way type structure, the utility model by traditional three-station 6 housings by horizontal change into vertical, be about to its 90-degree rotation, a pipeline horizontally set, its outer end mouth of pipe docks with isolating switch 4, a pipeline vertically arranges, its upwardly extending pipeline top adds cover plate, facilitate the installation of its inner components, the duct height size to downward-extension of its duct height size to downward-extension and isolating switch 4 is corresponding, the conductor that bus 1 conductor dbus of three-station 6 bottoms is crossed in three-station 6 connects, then be incorporated in isolating switch 4 and be connected with the conductor in isolating switch 4, such two buses 1 are just pooled in same interface and have all been pooled in isolating switch 4, and then be connected with current transformer 3 by isolating switch 4, realize being electrically connected to of equipment and bus 1.
Because the utility model is by two buses, 1 horizontal direction spread configuration, bus 1 top arranges isolating switch 4, another bus 1 top arranges three-station 6, three-station 6 is connected with current transformer 3 by isolating switch 4 again, the interface of such two buses 1 is just pooled in isolating switch 4, recycling isolating switch 4 docks with current transformer 3, the utility model has saved two threeways and has but still realized bus 1 and be connected with the conduction of interval equipment respectively, and due to the improvement of each component layouts, make Power station structure compacter, rationally, two threeways have been saved, not only reduced cost, also reduced the floor space in power station, simplified assembly manipulation, improve efficiency of assembling, also reduced interface simultaneously, reduced equipment leak rate.
The utlity model has rationally distributed, compact conformation, convenient for assembly, a kind of case 110kVGIS combined electrical apparatus altogether of feature that cost is low
