Description
Technical field
The present invention relates to transformer manufacture technology, particularly relate to a kind of transformator forced oil-circulation guide frame.
Background technology
Forced oil-circulation Directed cooling be large-scale power transformer conventional be a kind of efficient type of cooling, can be fast
Speed, the heat of generation is dispersed in cooling medium (air or water) by transformer oil when effectively transformator being run.At present,
Conventional forced oil-circulation guide frame has the disadvantage in that 1, owing to being limited by space, axial fuel inlet mouth quantity typically can only
Arranging 4, oil flow channel sectional area is little, in the case of transformer oil flow determines, enters the oil stream within winding inequality
Weighing apparatus, regional area oil Flow Velocity is too fast, is susceptible to oil flow electrification phenomenon on high voltage product, endangers transformer insulated；Office
Region, portion oil Flow Velocity is too slow, and the cooling to winding is insufficient, causes hot spot temperature of winding too high.Simultaneously in transformer oil can
Minute impurities, the moisture that can exist also can be directly entered the high field intensity region within winding, cause shelf depreciation, endanger transformator
Insulation；2, oil box metallic particles such as the welding slag that can produce when welding, weld rear oil box and has formed the space of closing, needed to set
Put operation hand hole metallic foreign body is cleared up, waste time and energy and clear up difficulty.Under oil stream drives, the metallic foreign body of residual can
Can enter inside winding, the safe operation of harm transformator；3, after transformator long-play, transformer oil can aging, product
The harmful substances such as oil generation mud.Owing to oil stream flow velocity in oil box is very fast, it is difficult to deposition.And it is deposited on that at winding terminal circle
At the dead angle that a little oil Flow Velocities are slow, cause stopping up of oil channel, be unfavorable for the heat radiation of winding.
Summary of the invention
For solving above-mentioned technical problem, the invention provides a kind of transformator forced oil-circulation guide frame, oil flow velocity fall
Flow equalization low, oily, does not produce oil flow electrification phenomenon, improves the safety within winding.
The technical solution adopted for the present invention to solve the technical problems is: a kind of transformator forced oil-circulation guide frame,
It includes winding and lower oil tank；Described winding is arranged with lower pallet；It is provided with between described winding and lower pallet and leans on
First insulating end ring in outside and the second insulating end ring in the inner part, described first insulating end ring and the second insulating end ring are all by paper
Circle forms with multiple cushion blocks are bonding；The paper circle of described first insulating end ring is rectangular dielectric circle；Described rectangular dielectric circle is inner circle
Outer square structure；It is additionally provided with insulating barrier between described rectangular dielectric circle and lower oil tank；Described lower oil tank, lower pallet,
Rectangular dielectric circle and insulating barrier surround bottom grease chamber jointly；Lower pallet is provided with four axial fuel inlet mouths.
Described bottom grease chamber is provided with oil-feed supervisor in the side of lower oil tank.
Oil ring is formed between described first insulating end ring and the second insulating end ring.
Beneficial effects of the present invention: a kind of transformator forced oil-circulation guide frame of the present invention, cancel oil box, increase every
Plate, increases the space of grease chamber, transformer oil plays the biggest cushioning effect, makes the minute impurities in transformer oil oil, water
Point, the hazardous material deposition such as greasy filth is in the bottom of grease chamber, it is to avoid enter deposition in winding and cause partial discharge phenomenon；Add
Width, to oil-in, makes the cross section of total oil inlet passage increase, and transformer oil can enter inside winding from whole circumferencial direction, fall
Low oily Flow Velocity so that oil Flow Velocity and flow more equalize, it is to avoid the generation of oil flow electrification phenomenon.
