Abstract

Monitoring the condition of oil-filled casing and other equipment with little oil is of great importance for the safe operation of power grid. In this article, through analysis of the existing hydrogen sensor selection, analysis of transformer bushing structure model, design a high-pressure oil casing in hydrogen gas on-line monitoring terminal which include LoRa, solidstate palladium alloy membrane hydrogen sensor and temperature sensor, the terminal can be real-time monitoring casing hydrogen content in the oil and the oil temperature, and real-time uploading data to the host. After application in substation, the effect is better. This paper describes the research status of hydrogen sensor and the application of wireless communication technology LoRa in electric power online monitoring and acquisition terminal, and introduces the software and hardware design of monitoring device in detail.
