Description
Technical field
The utility model relates to a kind of capacitor, and more particularly, it relates to a kind of Self-healing power capacitor.
Background technology
Self healing capacitor adopts single-layer polypropylene film as medium, surperficial evaporation the thin metal of one deck as conductive electrode.When applying too high voltage, polypropylene screen electricity weakness is breakdown, and breakdown point impedance obviously reduces, the current density flowing through sharply increases, and the coating that makes to metallize produces high heat, and breakdown point metallic conductor around evaporates rapidly loss, form coat of metal clear area, breakdown point recovers insulation automatically.
Capacitor unit group adopts the explosion-proof manufacture craft that stretches; when capacitor internal fault; can produce a succession of self-healing property collapse causes capacitor element internal pressure to increase; for avoiding causing capacitor case rupture; capacitor element internal structure is designed with pressure and breaks type dump mechanism (protective device); these protective devices are that nationality causes upper cover to heave by interior pressure increase, Copper Foil are pulled off and isolated from power, prevent that secondary disaster from occurring.
Wherein, internal pressure increases the two kinds of situations that include:
One, after self-healing process repeatedly, make thin metal gasification cause the permanent increase of internal pressure, and then pressure is broken protective device.
They are two years old; once or after the self-healing process of less number of times; thin metal gasification causes internal pressure to increase; but now not yet reach the pressure that pressure is broken protective device, yet the gasification of thin metal is declaring publicly it in the condition of high temperature, gas is in high heat expands state; now the expansion meeting pressure of gas is broken protective device; yet at gas, return to after normal condition, capacitor is actual is still operable, the thin metal of the part of just having volatilized.
Above-mentioned protective device adopts protection lead-in wire conventionally, and protection lead-in wire, after pressurized is broken, cannot engage again, and the second situation increasing for above-mentioned internal pressure, will cause misoperation, causes capacitor to reuse, and causes the wasting of resources.
