JZ Small Online On-Load Tap Changer (OLTC) Transformer Oil Filtration Unit

  • In order to adapt to the voltage of a large transformer, and on-load tap changer needs to be installed to adjust the voltage of the transformer. The use of this tap changer greatly reduces the operating cost of the entire physical life of the transformer, improves the usability of the transformer, requires no refuelling and carbonization, and no need to replace contacts. 
  • Online On-Load Tap Changer (OLTC) Transformer Oil Filtration 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.

   Description


Application of OTLC Transformer Oil Filtration Unit

  • JZ Series Small Online On-Load Tap Changer (OTLC) Transformer Oil Filtration Unit is mainly used for the bypass circulation filtration of the transformer high voltage switch.

Introduction of OTLC Transformer Oil Filtration Unit

  • Small Online On-Load Tap Changer (OTLC) Transformer Oil Filtration Unit manufactured by Yuneng oil purifier ensures that the related main electric equipment works safely during the maintenance period. 
  • When the main system is under normal operation, at the same time, the oil filter can effectively adsorb the trace water in insulation oil and intercept small mechanical particles through the bypass circulation filtration system, and control the cleanliness of the insulation oil and increased the insulation strength of the oil; it can ensure the electrical parameter such as water content, breakdown voltage and cleanness, etc. of the insulation oil will not be reduced, and extend the maintenance period of the transformer high voltage switch, etc and the service life of the transformer oil.

Characteristics of OTLC Transformer Oil Filtration Unit

  1. Functions contain a manual, auto, timing start, remote control, alarm, etc.
  2. Small size, low noise, stable running, easy to install and tear down.
  3. Oil filters damage protection: The machine will be shut down when the sensor detected the dewatering and impurities filters are damaged.
  4. Stainless steel shell: corrosion-proof, erosion-proof, dustproof.
  5. Problem alarm and display screen, easy to maintain.
