Description
Technical field
The present invention relates to a kind of insulating of electric measurement of high pressure goods, more particularly, the present invention relates to a kind of thermosensitive colour-changing insulated product that the power equipment contact is protected.
Background technology
The power equipment of outdoor operation; because its live part is exposed; the get an electric shock generation of security incidents such as injures and deaths, foreign matter overlap joint short circuit, corrosion is creepage of the personnel that often have; not only can influence the safe operation and the personal safety of power equipment; and accident is in case take place; direct and the indirect economic loss that causes is unable to estimate, so the protection of the safe insulation of power equipment electric conductor is very important.The contact that the power equipment electric conductor is connected, along with the energising continuity of running time, because a variety of causes, contact resistance can become greatly gradually, and then makes the power equipment tie point overheated, to certain degree, can cause broken string even equipment explosion.Therefore forecast that safely and effectively contact is overheated, seem equally particularly important.
The power supply department past does not cause enough attention to above-mentioned two problems, the most direct performance is exactly that the electric conductor of outdoor equipment and tie point are not carried out any insulating protection and overheated early warning measure, continuous generation along with security incident, power supply department has more and more been paid attention to this two problems by analyzing accident cause.Most of power supply departments carry out insulating protection by spraying coatings, twine insulating tape and adding methods such as overlapping heat-shrink tube to electric conductor, and the insulating protection of docking point generally uses ceramic cap, material contracting with heat protection box, polymethyl methacrylate protection box and silicon rubber contact protection box etc.But the overheated early warning of docking point never has good method, at present mainly adopts wax to touch test method(s), rainy day to see that junction point method, snow sky see the snow fusion method and use methods such as infrared thermometer to check whether contacts generate heat.
Although above-mentioned conventional method can solve the insulating protection of electric conductor and contact, the problem of bringing is exactly that the heating detection and the early warning of contact is cumbersome.After adopting ceramic cap, material contracting with heat protection box, polymethyl methacrylate protection box and silicon rubber contact protection box docking point to carry out insulating protection, adopt wax to touch test method(s), rainy day again and see that junction point method and snow sky see that the way that the snow fusion method checks whether contact generates heat is not very suitable just.When using infrared thermometer, must stay a thermometer hole in the appropriate location of protection box, and if each contact all to survey, workload is very big.
Aspect colour-changing insulated product, it is that 99217725.1 Chinese patent file discloses a kind of electronic component that utilizes color to judge performance that the patent No. is arranged, it comprises electronic element and pin thereof, be coated with insulating barrier on the electronic element outer surface, be provided with the temperature-sensitive layer that one deck can produce different colours with the difference of electronic element temperature at insulating barrier outer rim place; The mixing material of temperature-sensitive layer for being made by the temperature-sensing color-changing material of powdery is attached on the described insulating barrier with coating method; The temperature-sensitive layer also can be a heat discoloration LCD panel, is attached on the insulating barrier in the mode of pasting.It is said:, can find and change bad electronic component early by observing the electronical elements surface change in color.But this variable color temperature-sensitive layer is a layering coating form, and very thin thickness, mainly is suitable for protecting indoor low voltage component.
Summary of the invention
Above-mentioned shortcoming at prior art; the objective of the invention is to provide a kind of thermosensitive colour-changing insulated product; this thermosensitive colour-changing insulated product has following advantage: variable color is effectively responsive; can make very thick and complicated planform, be adapted to the protection of outdoor various poor weather and High-Voltage Electrical Appliances node.
For this reason, technical solution of the present invention is a kind of thermosensitive colour-changing insulated product, this insulated product has the fixed shape structure, comprise thermosensitive chromotropic paint in the material of this insulated product, organic insulating material, and also comprise heat filling in the material of described insulated product, described insulated product is by comprising thermosensitive chromotropic paint, organic insulating material, heat filling is at the even mixing of interior raw material and curing molding and get, wherein said heat filling is the metal oxide powder that does not disturb the colour developing of described thermosensitive chromotropic paint, and described organic insulating material is a polyolefin, hot shortness's polyolefin, organic silicon rubber, ethylene-propylene rubber, polymethyl methacrylate, the simple thing of thermoplastic elastomer (TPE) or the mixture or the compound of some kinds of these simple things.
The present invention adopts heat filling to conduct heat and temperature in order to produce the planform complexity, to have the thermosensitive colour-changing insulated product of suitable thickness structure: filter out some chemical inertnesses, colour developing inertia and heat conductivility good metal oxide powder as heat filling on the basis of test.Therefore, goods of the present invention can guarantee that variable color is effectively responsive, and be convenient to make very thick and complicated planform, thereby more can be adapted to the protection of outdoor various poor weather and High-Voltage Electrical Appliances node than traditional thermal discoloration coating or film goods.
Be the above-mentioned principal advantages of further optimization and refinement goods of the present invention, the present invention improves and also comprises:
