Embodiment Construction
[0021] An embodiment of the present invention provides a circuit protection device, comprising: a gas discharge tube having at least two electrodes, that is, a first electrode and a second electrode; a third electrode movably connected to the second electrode through a bimetal; When the working temperature is a normal temperature, the third electrode is electrically connected to the second electrode; when the working temperature exceeds the normal temperature, the bimetal strip is deformed so that the third electrode is connected to the second electrode The two electrodes are disconnected from the conductive connection.
[0022] Wherein, the gas discharge tube can be a diode or a multi-electrode tube; the normal temperature t is subject to the temperature range that the application environment of the circuit protection device can withstand, that is, t<T, and T is the application of the circuit protection device The limit temperature that the environment can withstand, and the ...
