The invention relates to a surge protection device, comprising at least one surge arrester and one short-circuit switching device which is connected in parallel with the surge arrester, can be thermally tripped and is spring-pretensioned, wherein the abovementioned means form one physical unit. The thermal tripping means is arranged in the region where heating of the surge arrester is expected when it is overloaded, and operating or surge current does not flow through said thermal tripping means. The thermal tripping means is in the form of a stop part which releases an unlocking slide of the switching device in the event of thermal overload. The switching device has two opposite contact pieces, wherein at least one of the contacts is of moveable design and is under spring pretension in the closing direction of the switching device. The opening state of the switching device is maintained by the unlocking slide, which is released by the thermal tripping means to close the switching device.
104 Modular, exchangeable surge protection system US15477744 2017-04-03 US09875830B1 2018-01-23 Michael David Gattis
A surge protection system provides surge protection to one or more circuits. Each circuit is connected to power and a surge protection module bridges the circuit such that the surge protection module absorbs surges from the power and/or the circuit. Being that, after exposure to certain amounts of surges, the surge protection modules lose effectiveness for surge protection, each surge protection module is independently removable and replaceable by a user without risk of personal injury from shock caused by making personal contact with the power and/or circuit. In some embodiments, a filter circuit is provided to filter out noise on the circuit. It is anticipated that the protection module includes indicators to inform a user that the protection circuit is operational and whether protection has been lost. Further, in some embodiments, a fuse is provided to protect the circuit from over current.

One form of the invention provides a method and apparatus for preventing an extraordinary electromagnetic pulse from reaching and rendering inoperative an electrical component of an electrical power system, wherein the component is located in a conductive path of the system that receives the pulse. The method and apparatus comprises the steps or means for detecting the presence of the pulse in the conductive path prior to the pulse reaching and rendering inoperative the electrical component. The pulse is diverted around the electrical component with a low inductance, high current capacity circuit relative to the electrical component before the pulse can reach and render the electrical component inoperative. The foregoing invention may beneficially utilize a high-speed current shunt comprising a flat conductive metal strap having a defined current-measuring region, a tapered parallel-plate transmission-line matching transformer attached to the current-measuring region and an output via a coaxial cable.

Novel circuits for providing ride-through during unpredictable power line disturbances are disclosed in connection with low-power electronic devices. Such low-power electronics devices are typically subjected to undesirable lock-ups and reboots under momentary power line disturbances such as voltage sags, voltage swells, and other momentary line power disturbances. Diagnostics and visual indication are also integrated in the circuits to allow consumers to correlate equipment lock-up and malfunction with power disturbances, and to provide service providers with various analytics and historical data on the recorded disturbances. To reduce cost, the disclosed circuits utilize a simple DC capacitor without any additional power conditioning switches or converters. In one exemplary embodiment, the disclosed circuits are embedded inside a power line cord to provide a ride-through during the brief interval of time such power line disturbances occur.
