摘要

湿度传感器用于监测变电站和开关柜保护系统环境中的湿度水平。高湿度导致保护场电气设备故障。为了监测开关设备和保护系统中的湿度水平，制作了一种简单廉价的微型湿度仪。将聚乙烯醇亲水性水凝胶膜沉积在谐振频率为433.92 MHz的表面声波器件上，制成传感器。用矢量网络分析仪研究了湿度从0 ~ 99%RH变化时传感器的响应特性。灵敏度低于30%RH，适用于气体绝缘变电站。

A Sensitive Surface Acoustic Wave Sensor for Monitoring Humidity for Substation Application

Humidity sensor is required to monitor the moisture level in the environment of substation and switchgear protection system. High humidity causes failure of the electrical apparatus in the protection yard. Simple inexpensive miniature humidity has been fabricated to monitor the humidity level in the switch gear and protection system. The sensor has been fabricated by depositing hydrophilic hydrogel film of polyvinyl alcohol on the surface acoustic wave device with resonating frequency of 433.92 MHz. Response characteristics of the sensor have been studied with vector network analyzer with the variation of humidity from $\sim 0$ to 99%RH. The sensitivity below 30%RH is suitable for gas insulated substation application.
