Description
(1) technical field
The present invention relates to the Local Members of a kind of transformator, particularly to a kind of transformator arm-tie.
(2) background technology
Along with the development of China's power system, transformator individual capacity and electric pressure are also improving constantly, in order to meet
Transformer core and the lifting of device body, the requirement of carrying, simultaneously take account of insulation, the manufacturability of assembling, usually used by folder from top to bottom
Arm-tie couples together.The stray transformer flux total amount determined when transformer capacity and impedance voltage is excessive and tends to integrated distribution
Time, usually can cause bigger stray loss in hardware, when unit total losses density is excessive, these metal structures
Part will produce hot-spot phenomenon.To this end, how on the premise of guaranteeing arm-tie and assembling construction machine intensity thereof, reduction is drawn
Stray loss in plate, is one of eternal problem of each transformator project planner.
(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 simple in construction, processing technology are strong, assembling side
Just, mechanical strength is high, can effectively reduce stray loss in arm-tie and avoid the transformator arm-tie of hot-spot.
The present invention is achieved through the following technical solutions:
A kind of transformator arm-tie, including iron core, iron core is respectively arranged at two ends with folder up and down, it is characterized in that: iron core is upper and lower
The folder both sides at two ends are connected by least two arm-tie respectively, are equipped with interval, arm-tie and folder between the most adjacent two arm-ties
Arm-tie insulating barrier it is provided with between part.
Arm-tie, arm-tie insulating barrier and folder are connected by arm-tie axle.
Arm-tie axle outer sheath is provided with insulation sleeve.
It is equipped with insulating stay between the most adjacent two arm-ties.
Arm-tie is three, is spaced apart 10mm between the most adjacent two arm-ties.
Arm-tie shaft end is provided with cover plate.
The invention has the beneficial effects as follows: reduce the width of arm-tie, efficiently avoid traditional structure and made when groove milling
The arm-tie become deforms, is difficult to the difficult problem such as correction, assembly process process difference, has stopped leakage magnetic flux through the notch in traditional structure arm-tie
Time in arm-tie, produce circulation, under the effect of leakage magnetic flux, effectively reduce the size of eddy current winding simultaneously；Simple in construction, add
Work manufacturability is strong, easy to assembly, mechanical strength is high, can effectively reduce in arm-tie stray loss and avoid hot-spot, it is adaptable to
Large and Medium-sized Power Transformer.

In figure, 1 iron core, 2 folders, 3 arm-ties, 4 intervals, 5 arm-tie insulating barriers, 6 arm-tie axles, 7 insulation sleeves, 8 insulating stays, 9
Cover plate.
(5) detailed description of the invention
Accompanying drawing is a kind of specific embodiment of the present invention.This embodiment includes that iron core 1, iron core about 1 are respectively arranged at two ends with
Folder 2, folder 2 both sides at iron core about 1 two ends are connected by least two arm-tie 3 respectively, between the most adjacent two arm-ties 3 all
It is provided with interval 4, between arm-tie 3 and folder 2, is provided with arm-tie insulating barrier 5.Arm-tie 3, arm-tie insulating barrier 5 and folder 2 are by arm-tie axle 6
Connect.Arm-tie axle 6 outer sheath is provided with insulation sleeve 7.It is equipped with insulating stay 8 between the most adjacent two arm-ties 3.Arm-tie 3 is three,
Interval 4 between the most adjacent two arm-ties 3 is 10mm.Arm-tie axle 6 end is provided with cover plate 9.
Use a kind of transformator arm-tie of the present invention, the mechanism produced according to eddy-current loss, and take into account processing technique
Property, by the arm-tie adjacent with transformer core 1 final stage lamination by opening magnet isolation tank together in the middle of the monolithic arm-tie of traditional transformer
Structure is improved to the design of three arm-ties 3, and three arm-ties 3 are arranged side by side, at a distance of 10mm between adjacent two arm-ties 3, and
Carry out spacing with insulating stay 8.The two ends up and down of each arm-tie 3 respectively have an arm-tie hole, and arm-tie assembling is first by three
Arm-tie 3 arranged in parallel is placed on iron core 1 (the folded level of iron core 1 and other assembling process are slightly)；Then place in the end of arm-tie 3
Good arm-tie insulating barrier 5, place folder 2 on the top of arm-tie insulating barrier 5, wherein arm-tie insulating barrier material selection high density,
The T4 cardboard of descreening；Then being placed in the installing hole that folder 2 pulls up board shaft 6 place by insulation sleeve 7, wherein insulation sleeve 7 selects
Make by the polyester resin plastic plate material with certain toughness；Finally arm-tie axle 6 is penetrated successively insulation sleeve 7, arm-tie insulation
Layer 5, arm-tie 3 are to be fixed together arm-tie 3 with folder 2.Arm-tie insulating barrier 5 and insulation sleeve 7 is used between arm-tie 3 and folder 2
Isolate, cut off the closed-loop path being made up of arm-tie 3, folder 2 etc., reduced and be directly entered arm-tie 3 from folder 2
Leakage magnetic flux, it is to avoid vented fire magnetic flux is produced circulating current in this primary Ioops.Arm-tie insulating barrier 5 and insulation sleeve 7 is utilized to incite somebody to action
After arm-tie 3 comes with folder 2 insulation, reduce and be directly entered the leakage magnetic flux arm-tie 3 from folder 2, the most effectively stop simultaneously
The circulation that traditional structure produces due to vented fire flux interaction in the loop that arm-tie and folder are formed.
