ENERVAC developed the On-Line tap changer oil purifier filter (TFS-2) to reduce the carbon, water and metallicparticles in tap changers. These contaminants are produced by arcingcontacts during the transfer of loads from tap-to-tap in the tap changer compartment. By using this system, operation and maintenance costs are reduced and the system#8217;s reliability is improved. Load tap changer problems can be effectively reduced with the use of ENERVAC#8217;s on-line oil filtration system.ENERVAC开发的在线净油器的滤波器抽头tfs-2减少碳在分接开关水metallicparticles。些污染物的移到水头水头的开关室中产生arcingcontacts。使用本系统减少了操作和维护成本提系统的可性# 8217。有分接开关的可以使用8217有效低ENERVAC #在线滤油系统。
