Abstract
在触点分开时，产生电弧，用动灭弧罩插入静灭
弧罩里，迅速剪切电弧。该法可研制高压无油开关，
代替目前油开关。该法可在低电压大电流情况剪切
所产生电弧。
Description
本发明，是一种灭弧新方法-剪切断弧法。
目前普遍采用是磁吹法和油浸法来切断触点分开时产生的电弧，以及真空灭弧等方法。但在高压设备中需要少油开关（即油浸法）该开关跳闸次数受限油即变质、甚爆炸等危险。
本发明剪切断弧法，就是克服上述缺点，特别是在高压设备中，该法可研制一种无油、触点寿命较长的高压开关。低压也可使用，如在大电流场合。
图〈1〉，剪切断弧法，动灭弧罩〈1〉，动触点〈2〉，静触点〈3〉，静灭弧罩〈4〉。
（a）动触点〈2〉与静触点〈3〉接合时。
（b）动触点〈2〉与静触点〈3〉分开时，产生电弧〈5〉。
（c）动灭弧罩〈1〉向前运动，插入静灭弧罩〈4〉里，切断电弧〈5〉。
