Description

A kind of self-adhering transposed conductor integral high-temperature bending strength experimental provision
Technical field
The utility model relates to a kind of material property experimental provision, especially for the experimental provision that detects transformer self-adhering transposed conductor high-temperature bending strength, belongs to the transformer technology field.
Background technology
At present, self-adhering transposed conductor has obtained extensive application in transformer, the insullac that has cohesive force in the skin brushing of each root transposed conductor, after the insullac drying, tens transposed conductors can be bonded to one, cementability therebetween is used to strengthen the bulk strength after transposed conductor is made coil, prevents that coil deforms when transformer is subjected to rush of current, improves the stability of transformer operation.Conventional art thinks that self-adhesion lacquer its performance after drying much variations can not take place, but new discovering is true really not so.Because conventional intensity detection can only be carried out at normal temperatures, therefore, the integral bending test of self-adhering transposed conductor also only limits to carry out at normal temperatures at present, experimental data can only reflect the performance under the normal temperature state, shortage is with the experimental data of temperature rising self-adhering transposed conductor performance change, this final performance parameter to the check product, still carry out deep research on this basis and all lack strictness basic data accurately, this becomes very stubborn problem in industry.In fact, because transformer moves at a certain temperature, the running temperature of transformer is far above room temperature, rising with temperature, therefore the transposition line bond properties changes and causes its bending strength to change, the bending strength that conventional sense data at ambient temperature can not accurate response transposed conductor under the transformer running temperature.
Summary of the invention
Technical problem to be solved in the utility model provides the self-adhering transposed conductor integral high-temperature bending strength experimental provision that a kind of simulation is carried out under the transformer service condition.
The alleged problem of the utility model is solved by following technical scheme:
A kind of self-adhering transposed conductor integral high-temperature bending strength experimental provision, its special feature is: it is made up of the oil bath chamber 8 of mechanism for testing 1 and splendid attire silicone oil 9, described mechanism for testing comprise base 12, crossbeam 2, guide pillar 15 and display instrument 14, crossbeam and two guide pillars are slidingly matched, the affixed pressure head 4 in crossbeam place, described oil bath experimental box is positioned on the base, be provided with bearing 11 in it, it is affixed with base 12 at the bottom of the oil bath experimental box case that bearing runs through, bearing top is provided with crooked test support 10, be provided with heating 7 in the oil bath experimental box, pressure transducer 3 is installed on the crossbeam.
Above-mentioned self-adhering transposed conductor integral high-temperature bending strength experimental provision is set up stirrer 13, and mixing arm immerses in the interior silicone oil of oil bath experimental box.
Above-mentioned self-adhering transposed conductor integral high-temperature bending strength experimental provision is set up thermopair 6, and described thermopair immerses in the silicone oil of oil bath experimental box.
The utility model can't reflect at existing self-adhering transposed conductor integral bending strength test its high-temperature behavior the problem specialized designs a kind of experimental provision of analogue transformer running environment, utilize this device to experimentize, can obtain self-adhering transposed conductor transposition line bending strength data under transformer temperature range of operation condition, these data are objective, reflect the performance characteristics under transposition line in working order accurately, the error of having eliminated conventional sense data and real data not to be inconsistent and having caused, thus reliable design considerations provided for improving transformer performance.The utility model is simple in structure, is easy to realize, and is workable.
