The use of the environment and life directly affects the life of the transformer, so how to prevent the transformer insulation aging has become our Chinese Miaoren worthy of attention and solve the problem.
1, the transformer should be inspected and parts of the oil seepage phenomenon, the transformer body no water, to prevent moisture and air into the transformer, causing damage to the insulation of the transformer aging.
2. The oil seal of the respirator of the transformer shall keep a certain oil level and keep it smooth. The desiccant remains dry and the moisture absorption effect is good.
3, regular inspection to ensure that the transformer explosion-proof membrane, safety relief valve is intact, to prevent direct communication with the air, resulting in transformer oil moisture content increased, so that the oil insulation performance deteriorated.
In 4, to the transformer oil supplement, attention should be paid to qualified conservator in oil, prevent oil supply caused by oil deterioration, and banned by the transformer to fill oil tank bottom, to prevent air and impurities into the tank at the bottom of the transformer body, especially to prevent the metal impurities into the transformer internal.
5, when the light gas pressure protection signal, to promptly take gas for inspection, in order to determine the composition and oil chromatographic analysis, identify the reasons, troubleshooting.
6, the operation of transformer light gas protection should be reliably put into, not allowed to put into operation without protection transformer, such as the need for protection will be temporarily disabled, there should be measures, should be immediately restored after the event.
7, we should focus on monitoring of transformer winding temperature, the temperature of upper oil, when approaching the alarm temperature, timely and comprehensive analysis comparison of the load, cooler and ambient temperature, and effective control, and strive to achieve the timely detection of potential transformer internal fault.
8, the oil flow indicator position should be carefully checked, once found submersible pump outage should be opened in time, otherwise the oil temperature will soon rise, threatening the safe operation of the transformer.
9, often check the transformer lightning arrester action recorder, and do the action record, found lightning arrester action, should try to stop the transformer and check.
10, the transformer body, oil samples, holes, bolts should be the focus of inspection, to prevent the maintenance personnel after sampling is not fastened, resulting in oil spills.
