Abstract
The utility model discloses a high-temperature-resistant large-current-resistant lacquered wire, which comprises a conductor layer and an insulated paint layer that is coated outside the conductor, wherein, the conductor layer adopts the silver-coated copper conducting wire, and also can adopt other conductors with low specific resistance, high heat conductivity and favorable processing property; the silver-coated copper conducting wire is coated with the high-temperature-resistant insulated paint layer; a self-stick paint layer that has high-temperature-resistant property and has binding property at a lower temperature is coated on the outer side of the high-temperature-resistant insulated paint layer according to the requirements. The lacquered wire can be used as the coil winding with strict requirements on temperature, load current, speed, small size, etc. The product of the lacquered wire has the advantages that the lacquered wire has good high-temperature resistant property, and can work reliably for a long time under the large current condition.
Description
Technical field
The utility model relates to a kind of novel electrical material, relates in particular to a kind of high temperature resistant, anti-big electric current enamelled wire.
Background technology
Along with torquer, motor, transformer, the continuous development of manufacturings such as engine, the continuous progress of the continuous variation of applied environment and science and technology, especially the development of aerospace industry, the special varnish envelope curve that needs high temperature resistant and anti-big electric current in increasing occasion, for example various angular speed sensers have obtained extensive use, because when the carrier movement angular speed is very big, coil is by big electric current, local pyrexia, cause localized hyperthermia, as use electric current to reach the lasting energising of 700 MAHs 2 minutes, and this accumulative total conduction time will be above 10 minutes, the common enamelled wire of Xiao Shouing can not satisfy these specific (special) requirements in the market, and therefore more exigence is a kind of high temperature resistant, the enamelled wire of anti-big electric current.
Summary of the invention
The purpose of this utility model is to provide a kind of enamelled wire high temperature resistant, the long-time reliably working of bearing great current that has.
Goal of the invention of the present utility model is achieved through the following technical solutions:
A kind of high temperature resistant, anti-big electric current enamelled wire, comprise conductor layer and be coated in the outer insulation enamelled coating of conductor, described conductor layer adopts the silver-plated copper lead, the conductor that also can adopt other to have low-resistivity, high thermal conductivity and possess excellent machinability, on described silver-coated copper wire, apply the high-temperature insulation enamelled coating, meet the enamelled wire insulated paint that heatproof requires as the high polyimide enameled wire insulating varnish of temperature resistant grade or other; Also can scribble high temperature resistant in the outside of described high-temperature insulation enamelled coating as required and have fusible self-adhesion enamelled coating under the low temperature slightly.
For making enamelled wire of the present utility model have characteristic high temperature resistant, anti-big electric current, must be from improving the insulating varnish thermal endurance and reducing conductor resistance rate both direction and start with, the preferred silver-coated copper wire of the conductor of this enamelled wire, the resistivity of silver is minimum in all metals, is 1.59 * 10
-8Ω m, therefore the thermal conductivity of silver can reduce the parts heating that high-current leading rises also greater than copper, and thermal diffusivity increases simultaneously, can also keep the copper cash good processing properties.
The utility model is high temperature resistant, the condition of work of anti-big electric current special varnish envelope curve is 250 ℃, continues 2min conduction time at every turn, can be interrupted energising and not damage operating current 700mA 6 times.The utility model enamelled wire can be used as to be used strict coil windings such as temperature, loaded current, speed, miniaturization.It is good that the utility model product has resistance to elevated temperatures, and it is good that the utility model product has resistance to elevated temperatures, work that can be reliably and with long-term under the big current condition and advantage such as tack is arranged.
