如何防止变压器绝缘老化?

使用环境和年限直接影响变压器的寿命,那么如何防止变压器绝缘老化就成了我们华淼人值得注意和解决的问题了。
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、济南变压器厂家http://www.jnwdsh.com运行中的变压器应检查和部位渗油现象,变压器本体无积水,以防止水分和空气进入变压器引起变压器绝缘老化损坏。
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、变压器的呼吸器的油封应保持一定油位并保持畅通,干燥剂保持干燥,保证吸湿效果良好。
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、定期检查保证变压器的防爆膜、安全释压阀完好,防止与空气直接连通,造成变压器的油中水份含量增大,使油的绝缘性能变坏。
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.
4、在给变压器补油时,应注意储油柜中的油质合格,防止补油而引起油质恶化,并且禁止由变压器的底部给油箱补油,防止空气和油箱底部杂质进入变压器身中,特别是防止金属杂质进入变压器内部。
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、当轻瓦斯保护动作后发出讯号时,要及时取气进行检验,以判明成分,并取油样进行色谱分析,查明原因,及时排除。
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、运行中的变压器轻瓦斯保护,应当可靠地投入,不允许将无保护的变压器投入运行,如工作需要将保护短时停用,则应有措施,事后应立即恢复 。
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、要对变压器绕组温度、上层油温进行重点监视,当接近报警温度时,要及时对负荷、冷却器及环境温度等进行对比性综合分析,并进行有效控制,争取做到及时发现变压器内部的潜在故障。
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、对油流指示器指示位置要仔细检查,一旦发现潜油泵停运要及时开启,否则油温会很快升高威胁变压器安全运行。
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、经常检查变压器的避雷器动作记录器,并做好动作次数记录,发现避雷器动作后,应设法停运变压器并进行检查。
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、对变压器本体油样孔螺栓要重点检查,防止检修人员取样后未紧固造成漏油。
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.
