1. Introduction and Application
Series FYZ OLTC (On Load Tap Changer) Insulation Oil Purifier designed and produced by FUOOTECH Group since 2005 is mainly used as a bypass circulation filtering system of OLTC (the transformer high voltage switch.). It can timely filter the oil while the transformer operates normally, or it can automatically filter the oil after switching off the OLTC.
This equipment can efficiently remove the impurities, dissociated free carbon, water and oxides to ensure the quality of oil, thus it can guarantee the oil's insulation, increase the switching times, postpone the repairing period, decrease the power cut off times, ensure the voltage's quality and improve the safety and reliability of the OLTC.
2. Product Flow Chart
Purification flow: OLTC Oil Purifier → Oil inlet → Oil pump → Impurities filter → Dewatering filter → Oil outlet → OLTC oil purifier.
Small Online On-Load Tap Changer (OTLC) Transformer Oil Filtration Unit manufactured by FUOOTECH oil purifier company ensures that the related main electric equipment works safely during the maintenance period.
Online On-Load Tap Changer (OLTC) Transformer Oil Purification Unit can remove free carbon and metal debris during the normal operation of the transformer system, and reduce the moisture content in the tap changer oil, to ensure the breakdown voltage and service life of the oil, This improves the safety and reliability of the on-load tap-changer, thus extending the maintenance interval.

Note: 1. The dimension and weight will be changed with changing of technical specs.
2. All the specs can be customized according to client's requirements.
4. Features
1). Work online with on-load working transformer or high voltage switch.
2). High quality filters remove the particles, impurities and moisture effectively.
3). All-weather Structure Case and standard control box, Made of Stainless steel.
4). PLC with touch screen installed: Displaying the filter's status and machine operation status.
5). Positive and negative direction control of the motor, protection of over-load of motor start and phase-lacking.
6). Automatically run this machine once after the operation of OLTC, the operation time can be set according to requirement from 0-99 hours, but it is usually set as 30 minutes. Another way is to proceed the filtration works every day at a fixed time lasting two hours.
7). Small volume, light weight, low maintenance cost and time.

9. Warm Notice on OLTC Transformer oil filtration plant
1) When the oil filter is not full of oil, it is strictly forbidden to start online
2) Before starting, the inlet and outlet valves of the oil filter and the switch must be in an open status
3) After the oil filter is installed or overhauled, the user is required to switch on for trial operation to prevent accidents
4) Never start the equipment when the oil inlet and outlet shut-off valve is closed
5) If it is found that the water content of the oil remains high, even if the alarm is not reported, the cause should be found out, the fault should be eliminated, and the water removal filter element should be replaced if necessary
6) The oil pipes must be cleaned after welding
7) Maure sure the inlet and outlet hoses are connected correctly
8) Make sure the cable connection and input voltage are correct
