摘要： The objective of the present invention is to provide an earth leakage circuit breaker which is capable of reliably detecting a leakage current of an alternating current component in a circuit as well as a leakage current of a pulsating direct current component and capable of blocking the circuit in response to the leakage current. The earth leakage circuit breaker according to the present invention comprises: a leakage current detection unit for outputting a leakage current detection signal according to the leakage current from a circuit; a conversion unit for outputting the leakage current magnitude of a fundamental wave component, a ratio of a third harmonic component, and a ratio of a positive pole peak current value to a negative pole peak current value, on the basis of the leakage current detection signal outputted from the current detection unit; and a control unit for comparing the leakage current magnitude of a fundamental wave component, the ratio of a third harmonic component, and the ratio of a positive pole peak current value to a negative pole peak current value, outputted by the conversion unit, with predetermined reference values to determine whether or not a leakage current of the alternating current component is generated or a leakage current of the direct current component is generated and to thereby output a trip control signal when it is determined that the leakage current of the direct current or alternating current component is generated.

摘要： The invention relates to a method for determining a value representative of the remaining useful life, RUL, of a capacitor, the method comprising the following operations:
- repeating for several iterations 1 to k, k being an integer greater than 1:
acquiring (301) environment measurements that are representative of the environment of the capacitor at a current iteration;
- based on previous environment measurements acquired at previous iterations 1 to k-1 before the current iteration, and on the received environment measurements at iteration k, calculating (307) at least one aging model;
- based on the at least one calculated aging model, determining (308-311) the value representative of the RUL of the capacitor

摘要： The present invention relates to a simultaneous inspection device of multiple secondary battery cell pouches, the simultaneous inspection device comprising: a support member installed for support; a movable member installed to face the support member; multiple pressing panels which are installed side by side between the support member and the movable member, and combined so that the gap between them can be adjusted by the back and forth movement of the movable member wherein the secondary battery cell pouches are inserted into each gap; a guide member for guiding the pressing panels to move in the direction necessary for adjusting the gaps; and a pressure driving unit for moving the movable member back and forth to pressurize and pressure-release the secondary battery cell pouch between the pressurizing panels on both sides.
