Claim 22:
23. A control system for controlling an interrupter, the interrupter being configured to be started by a startup current to interrupt a main electric circuit, the startup current flowing through an auxiliary electric circuit and having a current valve equal to or greater than a predetermined value, the control system comprising:
a driving unit including an intermediate electrical path to be connected to the main electric circuit; and
a driven unit to be connected to the auxiliary electric circuit,
wherein the driving unit is configured to, when an abnormal current having a current value equal to or greater than a prescribed value flows through the intermediate electrical path, use, as a drive source for driving the driven unit, the abnormal current flowing through the intermediate electrical path,
the driven unit is configured to supply the auxiliary electric circuit with the startup current by being driven by the driving unit,
the auxiliary electric circuit is connected to a current supply source configured to supply the startup current,
the driven unit is to be connected to the auxiliary electric circuit in series with the current supply source and is driven by the driving unit to close the auxiliary electric circuit,
the driven unit includes a semiconductor relay to be connected to the auxiliary electric circuit,
the driving unit includes:
a first winding forming at least part of the intermediate electrical path; and
a second winding electromagnetically coupled to the first winding, and

the semiconductor relay is driven by an induced current to close the auxiliary electric circuit, the induced current being produced in the second winding by the abnormal current flowing through the first winding.
