Description
Technical field
The present invention relates to capacitor preparation fields, more particularly to determine the polypropylene film electricity for being used as capacitor insulation material
The method and its application and verification method of heat ageing.
Background technique
With the rapid development of industry, either rail traffic, SVG, photovoltaic, smart grid, household electrical appliance etc.
Demand of the field to capacitor is increasing, and polypropylene film is widely used as the insulating dielectric materials in capacitor.It is poly-
Polypropylene film using and storage process in will inevitably by illumination, oxidation, thermal degradation the effects of, undergo aging
Journey.Film performance after aging declines, and has seriously affected the service performance of polypropylene plastics.Due to answering for its agine mechaism
Polygamy is also difficult to the variation of film performance caused by directly researching various senile causes at present, but is analyzed by testing
Research.Current degradation is mainly accelerated aging test method, it is to utilize ageing oven simulating natural environment in laboratory
Under certain aging actions carry out degradation, the method for obtaining test result.Currently, the general detection side of polypropylene film
Performance indicator in method " GB/T 13542.2-2009 electric insulation film part 2: test method " can not be intuitively anti-
Answer the aging as caused by electric stress and thermal stress in capacitor use process.Want electricity, the heat of accurate evaluation polypropylene film old
Change the long-duration experiments for needing for polypropylene film to be made capacitor and carrying out heating power-up.Such as made with polypropylene film
The voltage-capacity of the capacitor of insulating materials is 2200VDC-1000 μ F, and operating temperature is 70 DEG C, then according to " GB/T
17702-2013 power electronic capacitor " standard, durability experiment there are two types of method, a kind of method be under the conditions of 70 DEG C,
It is tested 500 hours under the conditions of 2200*1.4=3080VDC, another method is 2200*1.3=2860VDC item under the conditions of 70 DEG C
It is tested 1000 hours under part, if after experiment, condenser capacity decaying≤3% then judges durability qualification.And durability
What is mainly examined is exactly resistance to electric, the heat-resisting ability of polypropylene film.This has delayed finally sentencing for polypropylene film performance significantly
It is fixed, verifying expense is improved, the risk for increasing production and using.
Chinese invention patent publication number CN104749128A discloses a kind of old using infrared spectrum measurement polypropylene plastics
Change the method for time, comprising the following steps: (1) prepare two groups of polypropylene plastics samples；(2) first group is measured according to a conventional method to gather
The ageing time of each polypropylene plastics sample in Acrylic plastic sample；(3) using infrared spectrometer to each poly- in second group of sample
Acrylic plastic sample carries out infrared spectrum analysis, acquires spectral data, is drawn according to characteristic peak peak height and antioxidant content relationship
Standard curve calculates fit equation with Partial Least Squares founding mathematical models, that is, determines antioxidant content infrared spectroscopy point
Analyse equation；(4) polypropylene plastics to be measured is scanned with infrared spectrometer, the feature peak height of sample to be tested is substituted into antioxidant content
Infrared spectrum analysis equation, calculates antioxidant content, and reference standard data can determine polypropylene plastics ageing time.It should
Invention calculates polypropylene plastics ageing time using the oxidation preventive content that infrared spectrum measurement comes out, and the data obtained can only
For the durability estimation of polypropylene plastics under normality, the resistance to of (heating, power-up) polypropylene plastics is not used under specified conditions
Long property estimation.

Film, C1 group are underproof polypropylene films, and a variety of tests of A2 group, B2 group and C2 group are found, when experimental condition is with one
Determining A2 group and B2 group when temperature heating certain time, there is no variations, and the polypropylene film of C2 group hardens, and should add
500h needed for the hot time is far smaller than code test or 1000h, consequently found that polypropylene film harden temperature when
Contacting between intermediate node and the capacity attenuation rate of capacitor, and the mechanism hardened is the polypropylene film of C2 group by polypropylene
Certain macromolecular chains fragment into small molecule chain during polypropylene film is made in particle, these small molecule chains are specifically heating
Under the conditions of can volatilize, cause polypropylene film to be hardened, thus using the capacity attenuation rate of capacitor as measure polypropylene film it is resistance to
Polypropylene film for capacitor be individually heat-treated and then judges whether its bent angle alpha is greater than by the basis of long property index
30 °, the capacity attenuation rate of the bending angle and capacitor is established into corresponding relationship, this is core of the invention innovative point,
A kind of method and its application for quickly determining polypropylene film thermal-electrical aging are provided thus.
