    Abstract: An ignition device such as a spark plug (10) having center and ground electrodes (16, 18), at least one of which includes a firing tip (20, 22) formed from an alloy containing iridium, rhodium, tungsten, and zirconium. With the inclusion of tungsten and zirconium in the alloy, the percentage of rhodium can be kept relatively low without sacrificing the erosion resistance or reduced sparking voltage of the firing tip. In one embodiment, the firing tip (20, 22) contains 2 wt % rhodium, 0.3 wt tungsten, 0.02 wt % zirconium, and the balance iridium.

    Abstract: Представлен разрядник для грозозащиты элементов электрооборудования или линии электропередачи, содержащий разрядное устройство (дугогасительное устройство), высоковольтный электрод, низковольтный электрод и внешний технологический искровой промежуток, служащий для подключению разрядника к высоковольтной сети, который образован между высоковольтным электродом разрядника, и электродом высоковольтной сети, а также защитный промежуток, образованный между низковольтным электродом, подключенным к низковольтной части дугогасительного устройства и высоковольтным электродом. Защитный промежуток образован таким образом, что его канал разряда развивается между пятном электрода, с которого развивается разряд при подключении дугогасительного устройства к высоковольтной сети, и низковольтным электродом. Благодаря тому, что при срабатывании технологического промежутка между электродами на конце электрода образуется расплавленное металлическое пятно, и в пространстве вблизи него - плазменное проводящее облако, создаются благоприятные условия для пробоя защитного промежутка. Он пробивается при относительно низком напряжении, существенно меньшем, чем разрядное напряжение защитного промежутка известной конструкции между холодными электродами.

    Abstract: The present invention relates to a device for emitting acoustic pulses. The device, according to the invention, comprises an enclosing structure having at least one reversibly deformable wall and adapted to be put in contact with a liquid of propagation of acoustic pulses external to said enclosing structure. The enclosing structure is arranged so as to define, at least partially, an internal volume confined with respect to said liquid of propagation. Said internal volume is filled, at least partially, with a conductive liquid having an electrical conductivity lower than 5 mS/cm, at a temperature of 20 °C. The device, according to the invention, also comprises an assembly for generating acoustic pulses comprising at least a pair of electrodes, including a first electrode (or anode electrode) and a second electrode (or cathode electrode) spaced one from another. Said first and second electrodes are arranged so as to be in contact with said conductive liquid and so that a separation space between said first and second electrodes is occupied by said conductive liquid. Said first and second electrodes are electrically connectable to a power source and are adapted to receive electrical energy from said power source so that an electric discharge is generated between said first and second electrodes and, consequently, an acoustic pulse is generated and it is transmitted to said liquid of propagation of the acoustic pulses through the deformable wall of the enclosing structure.

    Abstract: The invention relates to an integrated flue-support construction (2) for a Marx generator (1) comprising several generator stages (3). According to the prior art, a flue (2) for purifying the air of switching spark gaps (4) is arranged separately from a support structure for the switching spark gaps (4), impulse capacitors (5) and series and parallel resistors (7, 8). According to the invention, the flue (2) adopts a supporting function for the switching spark gap (4) and individual or all electrical components (5-10) of the impulse wave switching circuit. According to one form of embodiment, the flue (2) consists of a triangular cylinder support construction (2), the side walls (11) being formed from insulating panels (11) and each receiving one of the electrical components: a switching spark gap (4), an impulse capacitor (5) and resistors (7, 8). The advantages of the invention are as follows: less complicated construction measures and reduced costs, compact construction with a small flue cross-section surface (22) and therefore, low self-inductance of the impulse wave switching circuit and a simple production process, simple transportation and simple handling due to the plug-in modules (14) for at least one generator stage, respectively.

    Abstract: 本发明提出一种光纤引入的光脉冲触发气体开关,解决了现有的电触发的气体开关和激光触发的气体开关因要求较高的脉冲幅值/激光束能量导致触发系统复杂、可靠性不足以及成本较高的问题。该光纤引入的光脉冲触发气体开关,包含至少一个触发间隙和一个自击穿间隙;每个触发间隙均并联光导开关,并相应配置光纤用于引入光脉冲触发。本发明充分利用光导开关触发要求低及气体开关高电压、大通流的优势,利用光纤引入的光脉冲触发光导开关,使得气体开关可在光纤传输的低能量光脉冲(可小于200μJ)作用下受控触发,大大简化触发系统规模及复杂度,促进脉冲功率源技术的发展与应用。
