浅析导电聚苯胺传感器对船舶封闭式组合电器中SF_6分解组分的气敏特性研究

Gas-Sensing characteristics of decomposition components in ship enclosed combinatorial conductors with conductive polyaniline sensors

船舶封闭式组合电器将电力系统变电站的断路器、互感器、母线等部件有机的组合成一个整体,是船舶的重要组成部分。六氟化硫具有良好的绝缘性能和灭弧性能,经研究发现,SF_6在常温下具有良好的化学稳定性,常常作为绝缘介质应用在船舶封闭式组合电器中。然而,随着电器运行年限的增加容易导致局部放热,进而导致SF_6气体发生分解,其分解气体与水蒸气及氧气发生化学反应,生成H_2S,SO_2等气体。聚苯胺材料是一种具有导电性能的高分子材料,常作为导电介质应用在传感器上,导电聚苯胺传感器对SF_6分解组分的检测具有高度灵敏性,有助于提高船舶封闭式组合电器的寿命。

Ship closed modular electrical substation circuit breakers, transformers, buses and other components of a combination of organic, is an important part of the ship. Sulfur hexafluoride has good insulation properties and arc extinguishing properties, the study found that at room temperature with good chemical stability, often used as an insulating medium in marine enclosed electrical appliances. However, as the operating life of the electrical equipment increases, it is easy to cause local exotherm, which in turn causes the gas to decompose. The gas decomposes chemically with water vapor and oxygen to generate gas. Polyaniline is a conductive polymer material, often used as a conductive medium on the sensor, conductive polyaniline sensor detection of decomposition components with high sensitivity, help to improve the life of marine enclosed electrical appliances.
