As multichannel rail switches have the advantage of low inductance,less erosion of electrodes and high capacity for power transmission,etc.,theyoften play an important part in power transmission.In this paper,a multichannel rail switch,which has three electrodes,was developed.The length of the gap between the two main electrodes and the position of the trigger electrode with sharp edge can be adjusted.The distribution along the rail gapwere revised on the basis of digital calculation.In addition,the rail switchwas investigated experimentally.Expirimental results indicate that,whenthe gradient of the trigger pulses reaches more than 4.1 kV/ns,the rail-gapcan be broken down in multichannels,but the number of the channels is notas great as expected.Only when does the gradient get to 10 kV/ns,manychannels are created simultaneously along the DC charged rail switch.Therail gap can be operated in a wide range,it may be triggered down to 12percent of its self-breakdown voltage.

多通道轨道开关具有电感小、电极损耗小、通流能力强等优点,在能量传输中发挥重要作用。本文设计了一种主间隙和触发极位置可调的轨道开关,通过计算对电场进行了调整。定量地表明了不同情况下开关间隙中的电场分布,并在此基础上对开关进行了部分特性实验。在触发脉冲上升陡度达4.1kV/ns时开关即可以多通方式运行,当触发脉冲陡度达10kV/ns时,间隙中的通道数令人满意。轨道开关的电运行范围也很宽,最低运行电压可达其自击电压的12%。

When the rise time of calibration-pulse is a constant, the slope of calibration-pulse is increased with the amplitude of pulse. The effect of calibration-pulse slope on the measurement of partial discharge is discussed in this paper. It is pointed out that the effect is related to the capacity C 0. If C 0>500pF, the effect can not be ignored.

Under a certain electric field strength of steep pulse, plenty of micropores occur in the cell membrane. The number and diameter of micropore increase rapidly with the increase of electric field strength, the membrane breaks and the cell dies at last. This phenomenon is called as irreversible electrical breakdown (IREB). To research IREB of tumor cell, integrated with power electronics and conventional high voltage pulse generator, an energy-controllable steep pulse apparatus for tumor treatment is developed....

Under a certain electric field strength of steep pulse, plenty of micropores occur in the cell membrane. The number and diameter of micropore increase rapidly with the increase of electric field strength, the membrane breaks and the cell dies at last. This phenomenon is called as irreversible electrical breakdown (IREB). To research IREB of tumor cell, integrated with power electronics and conventional high voltage pulse generator, an energy-controllable steep pulse apparatus for tumor treatment is developed. The peak value, width, frequency and rise time of the output pulse can be adjusted independently, so the energy of the output pulse can be easily controlled. The apparatus is applied in cell experiment after a detailed analysis of its operating principle and debugging in laboratory. The experiment results show that the device works steadily and satisfies the demand of medical experiment.
