THE POINTLESS DISCHARGING OF ACCUMULATOR AND ITS COUNTERMEASURE

    Graphical Abstract
    • Abstract
  • pointless discharging of the accumulator is a kind of recessive malfunction for the instruments charged by alternating or direct current used in seismological and geomagnetic survey.it may increase the frequency of the charging for the accumulator and shorten its service life.Taking DJ-1 earthquake recorder as example,we revealed the causes for pointless discharging of the accumulator,and analyzed the relationship between pointless discharging current and the wave-filtering capactiance as well as other factors quantitatively.The countermeasures are presented.
