1、Reduce the temperature
Oil-immersed transformers run for a long time, the temperature will rise, usually, the temperature is not easy to rise too high, but, if the long-term overweight operation, the temperature will be very high, then generally down, many insulation layer materials will be high temperature and embrittlement, therefore, reduce the temperature is to enhance the transformer life of a whole method
2、Prevent the working voltage from being too high
The requirements of oil-immersed transformer working voltage is not to exceed the rated voltage of 5, working voltage is too high then will prompt the oil-immersed transformer transformer core excitation current flow expansion, sometimes will promote the transformer core saturation, resulting in pulse current flux, promote the transformer core loss expansion and overheating. Too high working voltage will accelerate the embrittlement of oil-immersed transformers and reduce the service life of transformers, therefore, the working voltage should not be too high.
3、Avoid oil-immersed transformer load is very large
Oil-immersed transformer temperature is very big generally related to the load current of the load, the more load current, the higher the insulation layer temperature, on the contrary, the load current is small, the more low the insulation layer temperature. If the oil-immersed transformer in the load operation, a long time, the temperature will be very high, the internal insulation layer accelerated embrittlement, oil-immersed transformer use period will damage accelerated.
Comprehensive, if you want to enhance the use of oil-immersed transformers, it is necessary to run without load, in addition to avoid working voltage is too high, appropriate temperature reduction, pay attention to the usual maintenance of transformer machinery and equipment.
