Foreword

This standard was drafted in accordance with GB/T 1.1-2009 given rules. This standard and GB/T 11022, GB 1984, GB 1985 together. To simplify the representation of the same requirements, this standard reg number 11022 consistent with GB/T . Supplementary content of these clauses are given in the same reference under the heading, and additional terms numbered starting from 101. This standard uses redrafted law revision using IEC 62271-108.2005 "Part 108 high-voltage switchgear and control equipment. the amount 72.5kV and above constant voltage AC high voltage isolation breaker. " This standard and IEC 62271-108.2005 main difference is reflected in. --- Rated frequency. According to the actual situation of China's power grid, removing the IEC 62271-108.2005 rated frequency of 60Hz; --- Rated voltage. According to China's power grid, the voltage range is divided into. 72.5kV, 126kV, 252kV, 363kV, 550kV, 800kV; --- Terminals static load rating. According to the level of the voltage level of the IEC 62271-108.2005 in Table 1 and the terminal rated current range of static load value Modify considered in a multi-column isolation breaker situation, circuit breakers and disconnectors side terminal side terminal static load value; --- Increased Chapter 12. Effect of the relevant requirements of the product on the environment; --- Appendix A Figure A.3 increase the circuit breaker and isolating switch interlock mechanism Fig. The chapters in this standard, the order of the arrangement with the IEC 62271-108.2005 agreement, the contents of most of the provisions of IEC 62271-108. 2005 same, except that the main difference has been given instructions.

1 Overview

1.1 Scope This standard applies to the design and installation indoors or outdoors and run at a frequency of 50Hz system rated voltage 72.5kV and above AC isolation circuit breaker. Note 1. The rated voltage 72.5kV AC isolation breaker may refer to this standard. This standard was confirmed GB/T 11022, GB 1984 GB 1985 and applicable sections of the requirements, but also gives a unique kind of attachment means Canadian requirements. This standard covers the OFF position while meeting the requirements of the circuit breakers and disconnectors devices. This standard describes in detail the requirements for isolation breaker function independent interaction and clear these requirements with the circuit breaker and the separate compartment Leaving the independent claim related to the difference between.
