The GDT can further include a sealing portion implemented to join the edge portions of the first and second electrodes to form a chamber between the inward facing surfaces of the first and second electrodes. The GDT can further include an electrically insulating portion implemented to provide a surface that covers a portion of the inward facing surface of each of at least one of the first and second electrodes such that a leakage path between the first and second electrodes includes a path on the surface of the electrically insulating portion.

摘要： The invention relates to a lightning and overvoltage protection device for data networks, telephony services, electroacoustic installations or bus systems having at least two grid-side input terminals and at least two output terminals, to which the load that is to be protected can be connected, furthermore having a gas-discharge surge arrester that connects the input terminals and an inductance located between the respective input and output terminal. According to the invention, the inductances are configured as current-compensated inductors having a core and a primary winding and a secondary winding, wherein the load current flows through the windings in different directions so that the respective magnetic fields cancel out. In the event of transient overvoltages, the arising surge current is bypassed by means of a switching device that then closes at one of the two windings, for example the secondary winding, in such a way that, owing to the winding through which current flows, for example the primary winding, the core reaches saturation and the coupling between the windings is released, with the result that no voltage is established across the load and the voltage applied to the winding through which current flows ignites the gas-discharge surge arrester.

摘要： An electronic apparatus and an overvoltage protection structure thereof are provided. The overvoltage protection structure includes a first signal transmission end and a second signal transmission end. The first signal transmission end has at least one first side, and couples to a protected component through a conductive wire. The second signal transmission end has at least one second side, wherein the at least one second side corresponds to the at least one first side and is adjacent to the at least one first side. Therein, there is at least one gap between the at least one second side and the at least one first side, and the gap is positively related to a threshold voltage of the overvoltage protection structure.

摘要： A multi-step tube (1) of a ceramic material comprises a tube body (1) of the ceramic material having an inner wall (11) located inside the tube body (1). A surface of the inner wall (11) is formed with a plurality of steps (2). The steps (2) are formed to extend differently far inside the tube (1). A multi-layered gas discharge tube comprises the multi-step tube (1). An inner electrode (31) is disposed on a step (21), and an outer electrode (41) is disposed on an outer surface (13) of the tube body (1). A disc (51) is partially placed on a step (22) and the inner electrode (31) between the inner electrode (31) and the outer electrode (41) so that, in case of an electrostatic discharge, the discharge will only take place in the center of the multi-step tube (1) and not at the border of the isolated ceramic disc (51).
