1、基于热电堆的高压开关柜接点温度测量装置的设计学 生 姓 名： 夏婷婷 学 号： 3091232217 专 业 班 级： 09供用电技术（2）班 指 导 教 师： 李培江 摘 要高压开关柜作为电力系统中非常重要的电气设备。现代电力系统对电能质量的要求越来越高，相应地对高压开关柜的可靠性也提出了更高的要求。随着电网的发展和设备技术的提高，10，35kV系统开关柜在电网中已大量使用。而开关柜的内部过热现象已成为开关柜使用中的常见问题，由于开关柜体的密闭性，在一些负荷较重的地区，存在开关柜的温升超标问题。开关柜的温升超标，直接影响设备的安全稳定运行，而且，过热问题是一个不断发展的过程，如果不加以控制，
2、过热程度会不断加剧，并对绝缘件的性能及设备寿命产生很大的影响。目前，对电力系统内部使用的开关柜，严格遵守设备采购程序及技术政策，确保入网的开关柜都通过型式试验，尤其对温升的要求比较严格。运行中，负荷通常都不会达到开关柜的设计满容量，开关柜的温升问题应该不会很突出，但是实际情况并不尽然。开关柜内部实际温升情况，尤其是母排连接等部位，通常总是比型式试验测出的数据高。就会影响设备的正常运行与维护，所以本次论文研究利用非接触式的热电堆的高压开关柜接点温度测量装置的设计。热电堆是一种热释红外线传感器，它是由热电偶构成的一种器件，利用这种原理来实现测量温度。关键词：热电堆；高压开关柜；温度测量 目 录摘
