PROBLEM TO BE SOLVED: To provide a storage capacitor module which never mars the function as a whole of the capacitor device even if one part goes wrong and also is hard to cause short-circuit accident, etc., during maintenance and inspection. SOLUTION: This capacitor.module(10) for accumulation of electricity is equipped with a capacitor.cell(C) for accumulation of electricity such as an electric double capacitor, etc., a bypass current path(BP) to this capacitor .cell(C) for accumulation of electricity, a switch(SW) which connects either the capacitor cell(C) for accumulation of electricity or the bypass current path(BP) selectively to an output terminal(T1), and a control signal input terminal(CNT) which is supplied with a control signal to this switch (SW), and this can cut off a faulty capacitor module from the capacitor array consisting of these connected in series by forming a bypass current path selectively only in the faulty capacitor module. |
