T/CES 057-2021 Guidelines for Testing Dry Hollow High-Coupling Split Reactors

Scope

Scope: This document specifies the methods for routine testing, type testing, and special testing of dry-type hollow high-coupling split reactors, as well as the determination of test results. This document applies to the testing of dry-type hollow high-coupling split reactors with voltage levels ranging from 10kV to 500kV. Main technical content: This standard addresses the prominent issues of a lack of testing methods for dry-type hollow high-coupling split reactors with voltage levels above 500kV, insufficient equivalence testing methods, and technical standard gaps. It proposes equivalent testing methods that combine high voltage and high current, taking into account both cost-effectiveness and equivalence, to verify the performance of reactors. Based on technical specifications, it fills and improves the gaps in product testing guidelines and specifies the methods for routine testing, type testing, and special testing of dry-type hollow high-coupling split reactors, as well as the determination of test results. This standard applies to the testing of dry-type hollow high-coupling split reactors with voltage levels ranging from 10kV to 500kV. The main content of this standard includes: reactor test design and equivalence research; testing technology research; based on the determined test items and methods, researching the reactor's short-time and peak withstand current tests, insulation, temperature rise, mechanical life, etc.; clarifying measurement instrument requirements and result determination criteria.
