T/CES 002-2018 High-voltage direct current protection test device technical guidelines

Scope

Scope: This standard specifies the basic technical requirements, test function requirements, inspection methods and acceptance rules, packaging, transportation, storage, marking, labeling, user manuals, and quality assurance for high-voltage DC protection test devices. This standard applies to the design, production, selection, and testing of protection test devices for DC transmission projects with voltage levels of ±500 kV and above. Main technical content: With the increasing workload of testing and maintenance of high-voltage/ultra-high-voltage DC protection systems, and the continuous advancement and deepening of the standardization work for DC protection systems, the need to conduct on-site DC protection testing using high-voltage DC protection test devices has become increasingly urgent. At present, there are no corresponding standards and specifications for high-voltage DC protection test devices, and there is still a lack of unified regulations for the technical requirements and conditions, test functions and performance, and inspection rules of DC protection test devices. This results in a lack of technical specifications for the design, manufacturing, bidding, and engineering application of corresponding test devices. To address this, it is necessary to formulate technical guidelines for high-voltage DC protection test devices to guide the design, production, selection, and testing of test devices, so as to better serve the construction and maintenance of high-voltage/ultra-high-voltage DC transmission systems and ensure the safe and stable operation of the power grid. In order to standardize the functions, performance, and other related requirements of high-voltage DC protection test devices, and to meet the needs of acceptance testing, commissioning inspection, and operation and maintenance of high-voltage/ultra-high-voltage DC protection systems, this standard is formulated.
