More Information
Summary:The alternating current transmission circuit includes power supply circuit 11 and a switch circuit 12 coupled with the power supply circuit. The switch circuit includes a main control circuit 122, a surge/overvoltage detection circuit 13, and a first switch device 121 connected in series in the power supply circuit. The main control circuit 122 is signal connected with the first switch device 121 and configured to control on-off of the power supply circuit by controlling the first switch device. An input terminal of the surge detection circuit is connected with the power supply circuit, and an output terminal of the surge detection circuit is connected with the main control circuit. The first switch device may be a triac switching device. Various other embodiments are described (figs 3, 10 to 14, 17, 24). The protection arrangement may be provided with a power strip or socket (fig 31).
