Abstract
The hardware platen on relay protective panels is the functional demarcation point and the blind spot of condition monitoring between protection device and the control circuit of primary equipments. Realizing the condition monitoring of the hardware platen is the basic need to promote the application of the ubiquitous internet of things in the relay protection specialty. In this paper, a method based on the Hall sensing effect is proposed to detect the state of the hardware platen in the substation, which can realize the automatic detection of the state of the hardware platen without disturbing the outlet control circuit. This paper first proposed the hall element selection scheme for hardware platen state detection, and then developed the configuration scheme of hardware platen state detection device for two kinds of the hardware platen, separated type and line spring type, designed hardware platen state detection integrated circuit, based on that an experimental platform was constructed and the validity and reliability of the proposed scheme was verified.
