Abstract
The utility model discloses a direct connecting device for a 110kV GIS (gas insulated switchgear) and an oil and gas sleeve pipe of a main transformer. The direct connecting device is characterized by comprising a four-way communicating pipe and two three-way connecting pipes, wherein the four-way communicating pipe and the two three-way connecting pipes are detachably connected. After the connecting scheme of the direct connecting device is adopted, the operation of a 11kV system of a fan room is stable, dust in a blast furnace region is more, in addition, the GIS and the transformer of a fan room substation adopts the direct sealed connection, dust cannot enter the GIS and the transformer, the regular machine halt for dust cleaning is not needed, the safe operation of the main transformer and the GIS is ensured, and the economic benefits are obvious.
Description
Technical field
The utility model belongs to electrical connection arrangement, and concrete is the connection set of 110kV GIS and main transformer oil gas sleeve pipe.
Background technique
The safe operation of blast furnace blower is very important to blast furnace production, guarantees that 110kV system reliable power supply in blast furnace blower room is most important.Blower fan master motor adopts the mode of connection of circuit-transformer-motor unit to power, supply transformer of every typhoon machine master motor configuration, article two, draw loop 110kV power supply and deliver to 110kV switch gear room, blower station, deliver to the first side of two main transformers in blower station through the 110kV switch.Wind machine room 110kV system has adopted fully closed combined electric unit (GIS), and modes such as GIS and the Placement of transformer mainly contain that aerial condutor connects with transformer, oil gas sleeve pipe direct connection and cable connection, that most of electric substation has adopted is comparatively convenient, aerial condutor and the transformer connecting mode of less investment.Because wind machine room mill-type construction restriction, 110kV GIS and 110kV transformer can only adopt and be arranged vertically, like this GIS with just compare being connected of transformer difficultly, have the electrical distance weak point, problem such as can't adopt that aerial condutor connects.
Summary of the invention
In order to solve above-mentioned the problems of the prior art, the utility model provides a kind of 110kV GIS and main transformer oil gas sleeve pipe direct connection device, and the technical solution of the utility model is as follows:
A kind of 110kV GIS and main transformer oil gas sleeve pipe direct connection device, it is characterized in that: it comprises a four-way connecting tube and two three-limb tubes, the four-way connecting tube is connected by removably with two three-limb tubes.
Three-limb tube described above is the right-angle tee connecting tube.
Four-way connecting tube described above, two three-limb tubes are connected with transformer respectively and import 110kV GIS connection mouth.
After adopting the utility model connection scheme, wind machine room 110kV system is stable, blast furnace zone dust is bigger, and wind machine room electric substation is connected owing to GIS directly seals with transformer adopting, dust can't enter, do not need regularly to stop and carry out deashing, guaranteed the safe operation of main transformer and GIS, economic benefit is obvious.
