| Abstract: | By the thermopile infrared as temperature sensor,Precaution System for High-voltage switchgear has developed,which is based on MSP430 single chip as control and process core is designed in this paper.The system consists of temperature sensors,signal conditioning circuitry,microcontroller,RS485 network and PC component.System can achieve more than one switch cabinet contacts for real-time measurement of temperature and have temperature warning function.System of measurement error could reach 1℃ and under.Using RS485 network,the system may join in electric power control centre,the longdistance realtime monitoring of temperature of the contact inside the high voltage switchgear was carried out.The system provides over-temperature warning for high voltage switchgears,effectively prevent the occurrence of electrical fire. |
