Instructions for ZJA Two-stage Transformer Filter Core Purifier
2018/11/26 Viewers:
Common requirements of insulating oil for filter core purifier of ZJA two-stage transformer:
Generally, the dielectric loss of transformer oil measured at 90 C should be less than 0.5%. Naphthenic oil is a good material for manufacturing electrical oil because of its low pour point, good low temperature fluidity, good electrical performance, good thermal stability and thermal conductivity.
Indicators of insulation performance of oil filters for electrical appliances:
Insulation oil is mainly used for electrical insulation, mainly used in transformers, transformers, switches and other electrical appliances. Low temperature performance, oxidation stability and dielectric loss are the three main performance indicators of electrical insulation oil.
(1) Low temperature performance is the most important requirement index of insulating oil. It refers to the fluidity that oil can convection automatically in equipment, derive heat and cut off arc current instantaneously under low temperature conditions. Generally, the low pour point and low temperature viscosity of electrical insulating oil are required. The transformer oil is classified into three grades by the International Electrotechnical Association (IEA) according to the tilt point (the temperature at which the oil products are cooled in the standard tube until they lose their fluidity): - 30 60 ( The pour point of capacitor oil and cable oil is generally in the range of - 30 ~50 C.
(2) Oxidation stability is the second performance index of insulating oil, which is oxidized by heat and oxygen under electric field for a long time. In the past, naphthenic oil was used to produce oil with better oxidation stability under reasonable refining conditions, but the test proved that the oil with antioxidant and metal passivator had better oxidation stability.
(3) Dielectric loss is mainly a reference value of impurity content in transformer. It reflects the degree of dielectric loss of insulating oil under AC electric field. It is generally expressed by the tangent value of dielectric loss angle (Delta). TG delta is a very sensitive index, reflecting the degree of refinement, cleanliness and oxidative deterioration of oil. The value of TG delta increases when oil contains colloid, polycyclic aromatic hydrocarbons, or when mixed with water, impurities and oxidized products of oil. Generally, the dielectric loss of transformer oil measured at 90 C should be less than 0.5%.

The oil products with insulation performance mainly include transformer oil, oil switch oil, capacitor oil and cable oil.
Transformer oil is a kind of low viscosity oil, which is used in transformer and other equipment and plays the role of cooling and insulation.
(2) Oil switching oil is an insulating oil for oil-immersed switchgear, which used to be replaced by transformer oil.
(3) Capacitor oil is used for insulation impregnation or moisture insulation of capacitors (mainly power capacitors or electrostatic capacitors).
(4) Cable oil is a refined lubricant used for insulation, impregnation and cooling of cable, or a mixture of lubricant and other thickeners (such as soft wax, resin, polymer or asphalt).
