Description
Technical field
The invention belongs to the technical fields of wire and cable production, and in particular to a kind of anti-frequency converter multi-layer insulated electrical wire.
Background technique
Frequency converter is mounted on many electrical equipments extensively as effective variable velocity control device, and frequency converter is with number
KHz~tens of kHz are converted, these corresponding pulses can generate surge voltage, and there are following phenomenons for frequency converter surge, i.e.,
It is reflected at the beginning for the wiring that the discontinuity point of its transmission system internal impedance is for example connected or terminal etc., the result is that generating
It is applied with 2 times of voltage for being up to frequency converter output voltage.The output generated especially with the high speeds conversion element such as IGBT
The voltage gradient of pulse is high, so that even if connecting cable shortens, surge voltage is also high, and then the electricity as caused by the connecting cable
Pressure decaying is also small, as a result, generating nearly 2 times of the voltage of frequency converter output voltage.
In the electrical equipment coil of frequency converter relevant device such as high-speed transitions element, frequency converter motor, transformer etc.,
As magnetic wire mainly using the insulated electric conductor for being enameled wire.And as described above, in frequency converter relevant device, due to applying
There is nearly 2 times of the voltage of the frequency converter output voltage, therefore it is required that making as one of the material for constituting these electrical equipment coils
The frequency converter surge deterioration of enameled wire is minimum limit.
However, shelf depreciation deterioration is usually the phenomenon that electrical insulating material intricately generates following deteriorations: by the part
Caused by the deterioration of molecular chain scission caused by the collision of the charged particle of electric discharge and generation, sputtering deterioration, local temperature rise
Heat fusing or thermal decomposition deterioration, chemical deterioration caused by ozone etc. as caused by electric discharge.Therefore, because of actual part
Sometimes thickness can be reduced the electrical insulating material of discharge deterioration.
It is thought that the frequency converter surge deterioration of insulated electric conductor is also to deteriorate identical mechanism according to common shelf depreciation
And carry out.That is, the frequency converter surge deterioration of enameled wire is because the higher surge voltage of the peak value generated in frequency converter is insulating
The phenomenon that electric wire generates shelf depreciation, the film of insulated electric conductor is caused to deteriorate because of the shelf depreciation, i.e. high frequency partial discharge deterioration.
For nearest electrical equipment, it is desirable that insulated electric conductor as the surge voltage of hundreds of volt levels can be born.I.e.
The partial discharge inception voltage of insulated electric conductor must be above.Herein, so-called partial discharge inception voltage is using commercially available
The value that the device of referred to as partial discharge test device measures.Measuring temperature, the frequency of used alternating voltage, measurement sense
Degree etc. can change as needed, and above-mentioned value is measured at 25 DEG C, 50Hz, 10pC, and the voltage of shelf depreciation is generated.
The deterioration of the enamel-cover layer of the insulated electric conductor as caused by above-mentioned shelf depreciation in order to prevent, and not generated
The high insulated electric conductor of shelf depreciation, i.e. partial discharge inception voltage considers the tree for having low using relative dielectric constant in enamel-cover layer
Rouge and the method for increasing paint cladding thickness.However, for the resin of commonly used resin varnish, the phase of most of resin
It is between 3~5 to dielectric constant, there is no the especially low resins of relative dielectric constant.In addition, considering required by enamel-cover layer
In the case where other characteristics (heat resistance, solvent resistance, pliability etc.), actual conditions are may not can to select relative dielectric constant
Low resin.Therefore, to obtain higher partial discharge inception voltage, the thickness for increasing enamel-cover layer is indispensable.
However, in manufacturing process, increasing the number by sintering furnace, as conductor to increase the thickness of enamel-cover layer
The thickness of the overlay film being made of copper oxide on copper surface increase, the bonding force of conductor and enamel-cover layer thus can be caused to reduce.
For example, the number by sintering furnace is more than 12 times when the case where obtaining the enamel-cover layer of the thickness more than 60 μm.Pass through known to if
Sintering furnace is more than 12 times, then the bonding force of conductor and enamel-cover layer extremely reduces.
In order to improve the above problem, the Chinese invention patent of Patent No. ZL201380014979.1 discloses a kind of resistance
Frequency device surge insulated electric conductor, the insulated electric conductor is by the way that the enamel-cover sinter layer of certain specification and thickness is arranged in conductor periphery and squeezes out
Coated with resin layer makes insulating layer thickness membranization using additional at least 2 layers of structure, and makes it have higher shelf depreciation starting electricity
Pressure and excellent thermal aging resistance property.
Then currently, in today that electrical component is just developing towards miniaturization and lightweight, for electric product portability and
More stringent requirements are proposed for high availability etc., so that wherein element is also required to continuously improve, to adapt to its light weight
The requirement of change, in the electrical equipment of certain type, the insulated electric conductor for wherein anti-frequency converter is also in this way, some electrically set
Perhaps, anti-frequency converter insulated electric conductor in standby realizes certain lightweight；But the insulated electric conductor of anti-frequency converter surge is in guarantee property now
