牵引变电所开关设备安全在线监测系统研究

Online Monitoring System for detecting security of switch device in the traction substation

本文主要研究了牵引变电所内GIS设备中SF6气体浓度及其分解物的在线监测系统,该系统通过检测分析SF6气体浓度及分解产物,及时、有效地发现设备内的潜伏性故障,并进行设备故障定位。该系统的研究包括两个方面:硬件设计和软件设计。硬件设备是便携式气体检测仪,其中包括光离子检测、电化学传感器、多路传感器等模块。软件系统定义了各个模块之间的算法操作流程。

This paper mainly studied on the Online Monitoring System for concentration of SF6 gas and its decomposition products in the GIS equipment within the traction substation. The latent mulfunction in the machine could be timely and effectively discovered, and located by detecting the concentration of SF6 gas and its decomposition products. The study of the System included two aspects, such as hardware design and software design. Hardware device was a portable gas detector, which included photoionization detection module, electrochemical sensors module, multiple sensor modules and so on. Software system deifned the operational lfow of algorithms between the various modules.
