Summary :

The authors have studied the Penning effect and direct ionization of charged gases, Ne and Ar, in a gas tube protector, which is equipped with the trigger of carbon line and (Ba・Sr・Ca)O-applied electrode, instead of the radioisotope, and have successfully realized a quite high-performance protector. The present study, which has been conducted on the mixing ratio of Ne and Ar as well as on the effects of gas pressure on the sparkover voltage for the impulse voltage at various ramp speeds and on the impulse life characteristics, has clarified the following points. (1) The impulse sparkover voltage can be held low, if the Ar concentration is limited to from 5 to 30% and the gas pressure is set to about 100 Torr. The increase of capacitance and rise of sparkover voltage is infinitesimal, even if the 10 1,000 µs, 100A impulse current has been applied 100 times. (2) Holdover voltage is approximately 80 V, when the 10 1,000 µs, 100 A impulse current and 350 mA DC current are applied. (3) Compared with a conventional radioisotope-charged protector, the newly developed protector has a low sparkover voltage for a high ramp speed impulse voltage, and its glow discharge time is extremely short.
