真空有載分接開關
Vacuum type on-load tap-changer
本開關適用于交流10kV, 50Hz或60Hz，設備最高電壓在12kV及以下，額定電流在400A及以下的三相油浸式變壓器。本開關采用真空管來替代了傳統的銅鎢合金來轉換負載電流，故解決了開關切換頻繁，電弧觸頭燒壞，絕緣油的炭化問題，提高了機械，電氣壽命。延長了檢修周期，降低檢修成本。
The switch is applicable to three -phase oil-immersed transformer with AC 10kV, 50Hz or 60Hz, equipment highest voltage of 12kV and below and rated current of 400A and below. This switch uses vacuum tube to replace the traditional copper tungsten alloy to change the load current, so it solves the problems of frequent switch, burn out of arc contact, carbonization of insulating oil, then improves the mechanical and electrical life. The maintenance cycle is prolonged and the maintenance cost is reduced.
