Description
Technical field
The utility model is related to transformer manufacture technology, more particularly, to a kind of forced oil-circulation folder Oil Guide pipeline knot
Structure.
Background technology
Oil guiding box of the prior art is the structure for being welded in transformer lower oil tank bottom, the structure oil guiding box after welding
Inside there are a large amount of welding slags, welding slag is inconvenient to clear up and the hidden danger that causes the accident, installation procedure is complicated.
Forced oil-circulation Directed cooling be large-scale power transformer it is conventional be a kind of efficient type of cooling, can be fast
Speed, effectively transformer station high-voltage side bus when the heat that produces be dispersed into by transformer oil in cooling medium (air or water).At present,
Conventional forced oil-circulation guide frame has the following disadvantages：1st, due to being limited by space, axial fuel inlet mouthful quantity typically can only
4 are set, oil flow channel sectional area is small, it is simultaneously uneven into the oil stream inside winding in the case where transformer oil flow is determined
Weighing apparatus, regional area oil flow rate is spent soon, and oil flow electrification phenomenon easily occurs on high voltage product, is endangered transformer insulated：Office
Portion region oil flow rate degree is too slow, and the cooling to winding is insufficient, causes hot spot temperature of winding too high.Simultaneously in transformer oil can
The minute impurities that can exist, moisture can also be directly entered the high field intensity region inside winding, cause shelf depreciation, endanger transformer
Insulation；2nd, the metallic particles such as welding slag that oil box can be produced in welding, the space of oil box formation closing is, it is necessary to set after the completion of welding
Put operation hand hole to clear up metallic foreign body, waste time and energy and clear up difficulty.The metallic foreign body remained in the case where oil stream drives can
It can enter inside winding, endanger the safe operation of transformer；3rd, after transformer long-play, transformer oil can aging, production
The harmful substances such as oil generation mud.Because flow velocity of the oil stream in oil box is very fast, deposition is difficult.And it is deposited on that at winding terminal state
At the slow dead angle of a little oil flow rate degree, stopping up of oil channel is caused, is unfavorable for the radiating of winding.
Large-scale forced oil-circulation guide frame power transformer is used as the core high-energy equipment of project of transmitting and converting electricity, its Oil Guide
The structure quality of pipeline directly affects the technical performance and reliability of operation of transformer；And traditional technology is utilized in oil
Bottom portion sets metal Oil Guide pipeline, but with complicated, the difficult shortcoming of welding scarfing cinder, all in order to solve this problem
Most of manufactory all using method that three-phase integrated metal Oil Guide pipeline is set on lower clamping piece unshakable in one's determination, but its have the disadvantage from
Coil bottom is closer and is three-phase integrated, and stray field can be produced than larger added losses through metal Oil Guide road, even
Hot-spot can be produced on hardware, the reliability of operation for having greatly reduced transformer low.
Utility model content
Problem to be solved in the utility model is, for above-mentioned shortcoming of the prior art, propose improvement project or
Alternative, especially a kind of oil flow rate reduction, oily flow equalization, oil flow electrification phenomenon is not produced, is improved inside winding
Security, it is to avoid improvement or alternative of the stray field through metal Oil Guide pipeline.
Not enough for more than, we adopt in the design of SFP11-300000/220 non-excitation pressure adjustments structure of power transformer
With a kind of a kind of new new forced oil-circulation folder Oil Guide pipeline knot simple in construction easy to manufacture, convenient and practical
Structure.
To solve the above problems, the scheme that the utility model is used is as follows：A kind of forced oil-circulation folder Oil Guide pipeline knot
Structure, it is characterised in that the forced oil-circulation folder Oil Guide pipeline structure includes winding and folder web；Set below the winding
There is iron yoke cushion block；Coil supporting plate is provided between the coil of the iron yoke cushion block and winding；It is interval with the folder web curved
Plate and steel plate；Cardboard is fixed between the bent plate and steel plate；The cardboard creasing is into box；The folder web, bent plate
Surround a pipeline jointly with box；The pipeline is used as Oil Guide pipeline；The iron yoke cushion block and coil supporting plate enter provided with axial direction
Hydraulic fluid port；The axial fuel inlet mouthful is by Oil Guide pipeline and coil UNICOM.
Further, the forced oil-circulation folder Oil Guide pipeline structure according to above-mentioned design, it is characterised in that described
Folder web clamps winding by irony support plate；The irony support plate connection winding side is provided with magnetic masking layer.
Further, the forced oil-circulation folder Oil Guide pipeline structure according to above-mentioned design, it is characterised in that described
The two ends of box are connected with bent plate and Interal fixation respectively by insulated bolt.
Further, the forced oil-circulation folder Oil Guide pipeline structure according to above-mentioned design, it is characterised in that described
One end of folder web is provided with main oil inlet pipe.
Further, the forced oil-circulation folder Oil Guide pipeline structure according to above-mentioned design, it is characterised in that described
The bottom of folder web is provided with oil guiding box bottom.
Further, the forced oil-circulation folder Oil Guide pipeline structure according to above-mentioned design, it is characterised in that described
Oil guiding box bottom is mutually fixedly connected with folder web by welding.
Technique effect of the present utility model is as follows：The forced oil-circulation folder Oil Guide pipeline structure of the application utilizes folder abdomen
The Oil Guide pipeline of plate, bent plate and box formation instead of oil box, and then increase trapped fuel space, transformer oil be served very big
Cushioning effect.Make the hazardous material deposition such as minute impurities, moisture, greasy filth in transformer oil oil in the bottom of Oil Guide pipeline,
Avoid enter into winding and deposit and cause partial discharge phenomenon.The iron yoke cushion block and coil supporting plate use Oil Guide cardboard system
Into.
Structure design of the present utility model is not only simple to manufacture, cost is low but also reduces the added losses of transformer, is kept away
The reliability that hot-spot substantially increases transformer station high-voltage side bus is exempted from.
The forced oil-circulation folder Oil Guide pipeline structure of the application is utilized by folder web, bent plate and the molecular Oil Guide of box
Pipeline instead of metal oil box, it is to avoid the oil box that welding oil box is produced in welding slag, the forced oil-circulation folder of prior art is equal
It is to use to be welded, due to being the space of an opposing seal, because of the very difficult cleaning of welding slag that welding is produced inside it, and it is residual
If the welding slag stayed is not cleaned out, serious infringement can be caused to transformer, transformer service life is significantly reduced.
