F100 series on-line oil filtering device is mainly used for circulating filtration of transformer on load tap changer insulating oil. The device is used together with tap changer, which can effectively remove free carbon and metal particles in tap changer insulating oil under normal operation of transformer system, and reduce trace moisture, so as to improve the breakdown voltage and service life of insulating oil and effectively enhance the The safety and reliability of on load tap changer can reduce the times of power outage, prolong the maintenance period and improve the quality of power supply. 

Main characteristics of the device 
1. The control system adopts fx1s programmable control technology of Mitsubishi company, which has the functions of manual, automatic, linkage, timing start and operation time setting, and has the record of action times, total times of tap changer, phase sequence error protection, etc; Maintenance alarm and filter element replacement prompt, the control interface adopts Mitsubishi touch type f1020got full Chinese display, the man-machine dialogue interface is intuitive and easy to understand, and the operation is simple and convenient. 
Two stage filtration is adopted, with the former stage removing free carbon and other impurities, and the latter stage removing moisture. The two-stage filter elements are products of Italian filtrec SRL company or U.S. Norman company. The filter element accuracy reaches 1um, which meets the requirements ISO.NEPA And ANSI and other international standards. 
2. Box structure, with 2mm thick stainless steel plate as shell, rain proof design, high protection level, suitable for outdoor environment. 
3. When the temperature is lower than the set value (factory setting 0 ℃), the heater starts to work; when the temperature exceeds the set value (factory setting of 40 ℃), the fan starts to work; when the humidity is greater than the set value (factory setting 85% RH), the heater and fan start to work, to ensure that the device can work in a variety of environments and realize all-weather unattended operation.
