With the continuous development of infrared technology, infrared-based detection and diagnosis technology has become a new modern power equipment detection technology. Based on infrared technology, this paper proposed detection and diagnosis method of the transmission line porcelain insulators, including analysis on detection theory of IR imaging sensor, and infrared imaging map introduction. Through establishing porcelain insulator circuit calculation model, computing heating power of trouble insulators, this paper minutely analyzed the heating causes of trouble insulators. The paper provided a reference to the detection of transmission line porcelain insulators, which made it an important measure to ensure the safety and economic operation of electrical equipment.
In consideration of the slow development of informatization level of relay protection device system business process handling at present, upon the request of relay protection device full life cycle management, this text has put forward the anti-metal RFID technical system for relay protection device field management on the basis of RFID technology, covering the lectotype of tags and read-write device, tag encapsulation, safety protection method. which contributes to settle the problems in relay protection device management, avoid waste of resources, save the economic cost, significantly raise the relay protection management level and working effects, and improve the power grid running performance.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
