The main causes of the rupture of capacitor insulator. (1)Mechanical injury; (2)Excessive residual heat during sintering of glass powder insulator; (3)The welding temperature is too high or the heat is not uniform.

The main causes of corrosion or fracture of capacitor leads. (1) Electrochemical corrosion occurs under the action of electric field in high temperature environment; (2) Leakage of electrolyte along lead wire, which causes lead wire to be chemically corroded; (3) The mechanical damage of the lead wi

Main causes of leakage of Capacitor. (1) Under the action of electric field, the impregnating material can separate the liberation gas to make the pressure in the shell one liter; (2) The welding between the metal shell and the sealing cover of the capacitor is not good; (3) The insulation is not we

Main failure Mechanism causing deterioration of Electrical parameters of Capacitor. (1) Damp or surface contamination; (2) Silver ion migration; (3) Self-healing effect; (4) Electrical aging and thermal aging of dielectric; (5) Volatilization and thickening of working electrolyte; (6) Electrode corr

Main failure Mechanism of Capacitor caused by Open Circuit. (1) The "self-healing" occurs in the lead position, which insulates the electrode from the lead wire; (2) The contact surface of the outlet line and the electrode is oxidized, resulting in low level open circuit; (3) Poor contact between th

Main failure Mechanism of Capacitor Breakdown. (1) The dielectric material has defects or defects, or contains conductive impurities or conductive particles; (2) Electrical aging and thermal aging of dielectric; (3) Electrochemical reaction in dielectric; (4) Silver ion migration; (5) Mechanical dam
