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 the oil-immersed power transformer of 66kV～110kV electric pressure,
Usually require that the more and more of double earthing mode (ground connection after i.e. transformer core and folder are drawn respectively from oil tank of transformer),
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, between at the bottom of transformer body bottom and fuel tank, adopt
Isolated with insulant such as insulating boards, on the top of device body, simultaneously take account of transformator evacuation, lift by crane, carry, transport
Defeated wait working condition requirement, be designed with temporary positioning device in device body when design of transformer, i.e. transformator evacuation, rise
Hang, carry, under the process conditions such as transport, this temporary positioning device assembled consolidation, it is ensured that transformator becomes a rigid body, improve
It bears the ability colliding acceleration, and must be disassembled by this temporary positioning device in transformer test, operation phase, to guarantee
The hardwares such as apparatus for fixing transformer a little and reliable ground, thus reduce stray loss therein and avoid hot-spot phenomenon
Generation.But during repeatedly dismantling this temporary positioning device, one is to consume substantial amounts of human and material resources；Two be
In temporary positioning device unloading process, owing to the friction etc. between friction, spanner and the locating pin of screw thread will produce some metals
Powder, this is extremely disadvantageous to transformer insulation structure；Three is owing to this position is for being rigidly connected, to manufacturing tolerance, remnants
Deformation etc. require more harsh；Four is to run or under seismic acceleration effect, due to this temporary positioning device at transformator
Removing, 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, positioning seat
Inside being inserted with keeper, keeper top is provided with case lid, it is characterized in that: be provided with insulating washer in described positioning seat, location
Insert in insulating washer bottom part.
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 sewage sumps,
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, and crossbeam 2 welds
Being connected to positioning seat 3, be inserted with keeper 4 in positioning seat 3, keeper 4 top is provided with case lid 5, is provided with insulation in positioning seat 3
Packing ring 6, inserts in insulating washer 6 bottom keeper 4.Reverse frustoconic locating slot 7, insulating washer 6 inwall it is provided with in insulating washer 6
Being provided with sewage sump 8, insulating washer 6 outer wall is provided with oil seepage slot 9.Reverse frustoconic locating slot 7 within insulating washer 6 and insulating washer
6 generally eccentric settings.The internal reverse frustoconic locating slot 7 of insulating washer 6 is 3mm with the eccentric throw of insulating washer 6 entirety.Location
Part 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
