Description
Technical field
The utility model relates to the research fields of polypropylene film thermo parameters method, and in particular to a kind of polypropylene film temperature
Spend the measuring device of field distribution.
Background technique
Power capacitor plays irreplaceable role in current electric system, main application be filtering,
Reactive compensation.Polypropylene film is the primary dielectric material for being applied to power capacitor at present.Power capacitor is in operation
It is inevitably present electrode, dielectric heat phenomenon.One of the main reason for heat ageing is capacitor failure, the service life is with temperature
Rising and reduce.When environment temperature is higher, radiating condition is bad, capacitor internal temperature is higher, when overvoltage occurs,
Capacitor is easy self-healing, or even short circuit breakdown caused by self-healing failure occurs.
In the research of recent decades, some scholars are to the structural parameters of capacitor, metalized film parameter etc. expansion
Research, to reach the temperature rise purpose for reducing capacitor.However, by condenser dielectric polypropylene self-temperature field distribution
It studies less.
Utility model content
