真空有载分接开关
Vacuum type on-load tap-changer
本开关适用于交流10kV, 50Hz或60Hz，设备最高电压在12kV及以下，额定电流在400A及以下的三相油浸式变压器。本开关采用真空管来替代了传统的铜钨合金来转换负载电流，故解决了开关切换频繁，电弧触头烧坏，绝缘油的炭化问题，提高了机械，电气寿命。延长了检修周期，降低检修成本。
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.
