Abstract (en)
[origin: EP3309809A1] A direct-current interruption apparatus of an embodiment includes a current path, a commutation element including a first semiconductor switch, a second semiconductor switch, a conductive path, and a nonlinear resistor. The current path includes a first switch and a second switch which are non-semiconductor devices and connected in series, the first switch having a first withstand voltage, and the second switch having a lower withstand voltage than the first withstand voltage. The commutation element has one end connected with a connection node of the first switch and the second switch and includes an element having a charge/discharge function and connected in series with the first semiconductor switch. The second semiconductor switch is between and connects with the other end of the commutation element and one end of the first switch which is opposite to the other end of the first switch connected with the second switch.
