The high-temperature bonding strength tester is characterized by simple structure and strong maneuverability.
Description
Technical field
The utility model relates to a kind of transformer material property experimental provision, and the experimental provision especially for detecting transformer heat bonding enameled wire high-temperature bond strength belongs to the transformer technology field.
Background technology
At present, heat bonding enamelling wire has obtained extensive application in transformer, and its adhesive property is used to strengthen the bulk strength that transposed conductor forms coil, prevents that coil deforms when transformer is subjected to rush of current, improves the operation stability of transformer.Adhesive test for heat bonding enamelling wire only limits to carry out under the normal temperature at present, and experimental data can only reflect energy normal temperature adhesive property, lacks the experimental data that how to change with temperature rising heat bonding enamelling wire adhesive property.In fact, because transformer moves at a certain temperature, the running temperature of transformer is far above room temperature, rising with temperature, the bonding enamelled coating performance of heat bonding enamelling wire can change, therefore and these variations can cause the transposition line mechanical property to change, the bond strength that the conventional sense data can not accurate response transformer running temperature lower wire at ambient temperature.
Summary of the invention
Technical problem to be solved in the utility model provides the heat bonding enamelling wire high-temperature bond strength experimental provision that carries out under a kind of analogue transformer service condition.
The alleged problem of the utility model is solved by following technical scheme:
A kind of heat bonding enamelling wire high-temperature bond 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 comprises base 12, crossbeam 2, guide pillar 15 and display instrument 14, crossbeam and two guide pillars are slidingly connected, the crossbeam place is provided with upper chuck 4, 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 down dop 10, is provided with heating 7 in the oil bath experimental box.
Above-mentioned heat bonding enamelling wire high-temperature bond strength experimental provision is set up stirrer 13, and mixing arm is immersed in the silicone oil of oil bath chamber.
Above-mentioned heat bonding enamelling wire high-temperature bond strength experimental provision is set up thermopair 6, and described thermopair immerses in the silicone oil of oil bath chamber.
Above-mentioned heat bonding enamelling wire high-temperature bond strength experimental provision, described crossbeam place is provided with sensor 3, and sensor signal is by display instrument 14 outputs.
The utility model can't reflect at existing enameled wire bond strength experimental method 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 the high temperature cohesive strength data of heat bonding enamelling wire under transformer actual motion condition, these data are objective, reflect the performance characteristics under heat bonding enamelling wire in working order accurately, for heat bonding enamelling wire practical function in transformer direct experimental verification has been arranged, eliminated that conventional sense data and real data are not inconsistent and the error that causes.The utility model is simple in structure, is easy to realize, and is workable.
