This kind of capacitor utilizes hermetically-sealed construction. When the inner core is breakdown during the usage of capacitor, polypropylene film（BOPP）, the main material of core, is decomposed in the high temperature resulted from the breakdown, causing a lot of gas but cannot be released. The gas in the capacitor increases the inner pressure, which deforms the cover of capacitor and makes it bulge outward Since the rivet connects terminals, insulated bowl, sealing ring and capacitor cover as the assembly, other parts of this assembly move above with the capacitor cover. Copper foil sticks to the explosion-proof block which is fixed in the capacitor. When the capacitor cover moves above, copper foil cannot move and will be pulled off if the capacitor inner pressure meets a certain level. In this way, the core of capacitor disconnects with the outside power supply and breakdown of core is terminated, so as to activate protection.
1.The capacitor should be used under the rated specifications.
2.The capacitor should be installed in position with good ventilation and heat dissipation.Ambient temperature should not exceed 70℃.
3.The maximum voltage for the capacitor is1.1times of rated voltage,maximum curent is 1.3 times of rated current and maximum output is 1.3 times of rated output.
4.The capacitor should be used under altitude of 2000m.
5.The residual voltage when applying voltage should not exceed 10% of rated.
