Sustainment of Insulation for High Voltage by the combination of Porcelain Insulators with cutting parts
抄録
A method of the sustainment of insulation for high voltage by porcelain insulators is to enclooe deeply both metal electrodes with the porcelain insulators. Therefore, the methode has a fundamental weak point of water stay after rainfalls. For avoiding the water stay, the porcelain insulators were cut in the radial direction. The sustainment for high voltage by the combination of the porcelain insulators with cutting parts are examined in this experiment.
It is found that the combination of the porcelain insulators with the cutting parts by rotation of above 15 degree alternately, sustains the same voltage as the insulators without cutting part do.
懸垂碍子の高耐電圧維持の方法は両方の電極を碍子の絶縁物で深く囲むことである。この方法は雨が降れば雨水が溜まるという基本的な弱点を持っている。この雨水が溜まるということを避けるため,碍子に半径方向に切れ目をいれた。この実験では切り欠き部をもつ碍子の組合わせによる高耐電圧の維持について調べた。切り欠き部をもつ碍子を交互に15度以上回転させた碍子の組合わせは切り欠き部をもたない同じ数の碍子と同じ電圧まで耐えることが分かった。
