- Abstract:
- There are plenty of intrinsic cation states on the surlace of nano-semiconductor crystals.When theerystals contact the transformer oil,surface states that can capture electrons easily are formed. In this paper TiO2 nano-powders with different surface modifications have been used to improve the property of transformeroil ( Kelamayi 25 ). The modifcation effeets of nano-power’s on insulating property of transformer oils havebeen investigated, And the modifying effects of TiO2 nano-powder with different concentrations on transformeroil have been studied. The breakdown property tests and fitting results show that TiO2 nano-powder can improve the breakdown properties of transformer oil and within some concentrations,the higher the concentrationof TiO2 nano-powder , the better the power frequeney insulating property of modifying transformer oil. Besides,The modifying agents play a key role in the dispensability of Ti0, nan-powder in the transformer oil. With theincreasing of nonpolar segment in the modifying agent, the breakdown property of the modified oils gets moreenhancements.
