Description
(1) technical field
The present invention relates to a kind of transformator, particularly to a kind of transformer body positioning device.
(2) background technology
Along with the increase of transformator individual capacity, for 66kV～110kV electric pressure oil-immersed power transformer and
Speech, usually requires that double earthing mode (ground connection after i.e. transformer core and folder are drawn respectively from oil tank of transformer) increasingly
Many, this technical measures contribute to reducing leakage magnetic flux stray loss in the hardwares such as folder, and stray transformer flux
Total amount its effect the biggest is the most notable.In the past, in order to implement this technical measures, at the bottom of transformer body bottom and fuel tank it
Between, use the insulant such as insulating board to be isolated, on the top of device body, simultaneously take account of transformator evacuation, lift by crane, remove
The working condition requirements such as fortune, transport, are designed with temporary positioning device, i.e. take out very at transformator when design of transformer in device body
Empty, lift by crane, carry, under the process conditions such as transport, this temporary positioning device assembled consolidation, it is ensured that transformator has become one just
Body, improves it and bears the ability colliding acceleration, and must be dismantled by this temporary positioning device in transformer test, operation phase
Fall, to guarantee the hardwares such as apparatus for fixing transformer a little and reliable ground, thus reduce stray loss therein and avoid office
The generation of portion's superheating phenomenon.But during repeatedly dismantling this temporary positioning device, one is to consume substantial amounts of manpower, thing
Power；Two is in temporary positioning device unloading process, will produce due to the friction between friction, spanner and the locating pin of screw thread etc.
Some metal dusts, this is extremely disadvantageous to transformer insulation structure；Three is owing to this position is for being rigidly connected, to manufacturing public affairs
Difference, residual deformation etc. require more harsh；Four is to run or under seismic acceleration effect, owing to this positions temporarily at transformator
Removing of device, device body is a weak spot.
(3) summary of the invention
The present invention is in order to make up the deficiencies in the prior art, it is provided that a kind of rational in infrastructure, mechanical strength is high, good manufacturability,
Production efficiency is high, reliability is high, the convenient transformer body positioning device of scrubbing.
The present invention is achieved through the following technical solutions:
A kind of transformer body positioning device, including the crossbeam being arranged at above iron core, crossbeam is welded with positioning seat, fixed
Being inserted with keeper in the seat of position, keeper top is provided with case lid, it is characterized in that: be provided with insulating washer in described positioning seat,
Insert in insulating washer bottom keeper.
Being provided with reverse frustoconic locating slot in described insulating washer, insulating washer inwall is provided with sewage sump, insulating washer outer wall
It is provided with oil seepage slot.
Reverse frustoconic locating slot within described insulating washer and insulating washer generally eccentric setting.
The internal reverse frustoconic locating slot of described insulating washer is 3mm with the eccentric throw of insulating washer entirety.
Described keeper is arranged over positioning cap.
The invention has the beneficial effects as follows: without the positioner of puller body in transformer test, running,
Add at this and the mechanical strength of whole device body, simplify production process；Increase simultaneously and to coordinate between crossbeam with case lid
Tolerance；There is the advantages such as rational in infrastructure, mechanical strength is high, good manufacturability, production efficiency high, reliability is high, scrubbing is convenient；
It is applicable to 66kV～330kV electric pressure and the oil-immersed power transformer for big-and-middle-sized capacity.
(4) accompanying drawing explanation
The present invention is further illustrated below in conjunction with the accompanying drawings.
Accompanying drawing 1 is the structural representation of the present invention；
Accompanying drawing 2 is the insulating washer main TV structure schematic diagram of the present invention；
Accompanying drawing 3 is the insulating washer plan structure schematic diagram of the present invention；
In figure, 1 iron core, 2 crossbeams, 3 positioning seats, 4 keepers, 5 case lids, 6 insulating washers, 7 reverse frustoconic locating slots, 8 collection
Dirty groove, 9 oil seepage slots, 10 positioning caps.
(5) detailed description of the invention
Accompanying drawing is a kind of specific embodiment of the present invention.This embodiment includes the crossbeam 2 being arranged at above iron core 1, crossbeam 2
On be welded with positioning seat 3, be inserted with keeper 4 in positioning seat 3, keeper 4 top is provided with case lid 5, is provided with in positioning seat 3
Insulating washer 6, inserts in insulating washer 6 bottom keeper 4.Reverse frustoconic locating slot 7, insulating washer 6 it is provided with in insulating washer 6
Inwall is provided with sewage sump 8, and insulating washer 6 outer wall is provided with oil seepage slot 9.Reverse frustoconic locating slot 7 within insulating washer 6 and insulation
Packing ring 6 generally eccentric setting.The internal reverse frustoconic locating slot 7 of insulating washer 6 is 3mm with the eccentric throw of insulating washer 6 entirety.
Keeper 4 is arranged over positioning cap 10.
Using a kind of transformer body positioning device of the present invention, case lid 5 and positioning seat 3 are directly by keeper 4 and exhausted
Edge packing ring 6 links together, its reverse frustoconic locating slot within insulating washer 67 and insulating washer 6 generally eccentric setting,
Its eccentric throw is 3mm so that the fit tolerance scope between transformer box cover 5 and iron core 1 upper cross-beam 2 is by original zero-deviation
(i.e. requiring that case lid 5 hole centre line overlaps with positioning seat 3 centrage) be extended to centered by insulating washer 6 integral central,
With its face of cylinder as radius of distance between internal reverse frustoconic locating slot 7 center so that assembly technology obtains further
Simplify.The assembling mode of this positioner is: weld the stage at crossbeam 2 and according to drawing requirement, positioning seat 3 is welded on crossbeam 2
On；In the transformator general assembly stage, the insulating washer 6 made in advance is put into positioning seat 3, then cover case lid 5, will be fixed
The afterbody of position part 4 rotates in the reverse frustoconic locating slot 7 within insulating washer 6 by the positioning screw hole on case lid 5, due to
This reverse frustoconic locating slot 7 has certain tapering, under the frictional force effect between insulating washer 6 and keeper 4, and felt pad
Circle 6 can be oneself positioning seat 3 in and rotate and regulate, to reach optimal locating effect.If encounter case lid 5 and folder crossbeam 2 it
Between owing to manufacturing or the bigger situation of residual deformation deviation, it is also possible to insulating washer 6 is individually revised, effectively stops
Do over again and cause general assembly to produce because the weld interval between fuel tank hole, location or regulation positioning seat 3 and crossbeam 2 is the longest
Process is detained.Being provided with sewage sump 8 additionally, due to insulating washer 6 inwall, outer wall is provided with oil seepage slot 9, and insulating washer 6 can collect oil
Hole, case location enters into the impurity in transformator or the metal dust produced during keeper 4 screw thread rotation, and can be
Easy cleaning during suspended core maintenance, considers the immersion oil manufacturability of this positioner simultaneously in the design process.It has structure and closes
Reason, mechanical strength height, good manufacturability, production efficiency height, reliability high.Insulating washer 6 is by the polyester resin of high intensity
Plastic plate makes, and this material not only has certain insulation characterisitic, and has certain toughness, contributes to decay iron core and passes through
Positioner is delivered to the acoustical power of case lid 5, and to reducing, transformer noise is significant；Insulating washer 6 has certain
Store up miscellaneous function.
