Mobile / Stationary
TF transformer oil reconditioning unit are manufactured with a welded, painted steel chassis. The frame can be adapted as a mobile or stationary unit. The TF series is available for some models as a mobile unit on a trailer, for transport on public roads or as a stationary unit delivered with or without cover plates or canopy. Also delivered assembled in a container of any size is another possibility. Typically a 10-foot storage container.
Filtration and heating
An oil heater with several heating elements heats the oil to desired temperature by means of indirect heating of the oil. The heater also partially functions as a heat accumulator and prevents major temperature changes during operation. The heating elements are thermostatically controlled and automatically heat the oil to the set temperature. The heating group has high capacity and a large heating area but with a low surface effect of 1.0 Watt/cm² to prevent hot spot cracking of the oil.
Particle filtration is done with a cartridge filter. It is easy to change the filter cartridge in the filter housing and the 7" HMI screen gives an alarm to the operator when it is time to change the filter cartridge.
TF filterpatron filtrerar transformatorolja enligt SAE ARP4205, CST kod 08/04/01.
Degassing
The degassing principle is based on an even flow of oil over specially developed Raschig rings. With this process, a controlled and highly efficient degassing is obtained.
Single stage degassing
Avgasning i ett steg med lamellvakuumpump. Vid genomkörning reduceras vattenhalt och partikelmängd. Trycket i vakuumavgasaren ska inte understiga 1 mbar. Behandling av oljan ska ske säkert och med ett tryck som är högre än transformatoroljans ångtryck. Detta för att minimera riskera att plocka bort tillsatser som tillverkaren adderat till isoleroljan t.ex. inhibitor etc. Därför har vi ingen rootspump i våra standardutrustningar.
Accessories
Standard equipment included in the TF-series transformer oil reconditioning units:
- Inlet hose 10m incl. lockable camlock (Autolock)
- Outlet hose 10m incl. lockable camlock (Autolock)
- Suction nozzle for oil filling (Use with barrel or IBC)
- Hoses for draining the system
Options
- Process monitoring via router/sms/GSM. With this technology, you can read measured values, operating functions, receive any operating alarms and carry out troubleshooting in real time.
