Scope
Scope: This document specifies the system composition and functions, performance requirements, performance tests, detection implementation, and application requirements for characteristic parameter calculation and fault diagnosis of high-voltage switchgear coil current detection technology. This document applies to the technical requirements, performance testing, and on-site application of high-voltage switchgear coil current detection; Main technical content: This standard specifies the system composition and functions, performance requirements, performance tests, detection implementation, and application requirements for characteristic parameter calculation and fault diagnosis of high-voltage switchgear coil current detection technology. This standard applies to the technical requirements, performance testing, and on-site application of high-voltage switchgear coil current detection. This standard consists of 6 chapters, including scope; normative references; terms and definitions; detection system; detection implementation; and result application. The main structure and content of the standard are as follows: - Chapter 1 "Scope" explains the main content and scope of application of the standard. - Chapter 2 "Normative References" lists the 5 national standards and 1 power industry standard referenced by this standard. - Chapter 3 "Terms and Definitions" provides the terms and definitions related to coil current detection technology, which facilitates the understanding of current waveform characteristics and data analysis by standard users. It also introduces the concept of "first operation" of switchgear, which changes the long-term state of the actuating mechanism before the first operation. Detecting the coil current during the first operation makes it easy to detect potential problems with the actuating mechanism and other components. - Chapter 4 "Detection System" specifies the requirements for the detection system, including: - Section 4.1 specifies the
