摘要： A vacuum exhaust element of a vacuum switch has an ordinary withstand voltage because the vacuum vessel and power source element are grounded, therefore not requiring the high voltage to be taken into consideration. This way, the vacuum exhaust element is miniaturized and it is safe for a worker to touch the vacuum vessel and the vacuum exhaust element when performing maintenance and/or inspection.
