IEC TR 62757:2015+A1:2019是一份技术报告，涉及高压直流（HVDC）系统、静止无功补偿器（SVC）和柔性交流输电系统（FACTS）的变流器及其阀厅的防火措施。它主要供负责发布新换流阀和阀厅技术规范的公用事业公司和顾问使用。它涉及使用线路换向转换器（LCC）或电压源转换器（VSC）技术的HVDC项目中的火灾事故，大多数火灾和火灾事故的例子都来自这些项目。本技术报告还介绍了SVC和FACTS的换流阀和阀厅。本技术报告提供了在准备这些系统规范时需要考虑的一般建议。特定项目的具体要求需要明确规定，并由供应商和买方共同商定。该合并版本由第一版（2015年）及其修正案1（2019年）组成。因此，除本出版物外，无需下令修订。

IEC TR 62757:2015+A1:2019, which is a technical report, deals with fire prevention measures on converters and their valve halls for high voltage direct current (HVDC) systems, static VAR compensators (SVC) and flexible AC transmission systems (FACTS). It is intended to be primarily for the use of the utilities and consultants who are responsible for issuing technical specifications for new converter valves and valve halls. It concerns fire incidents in HVDC projects using line commutated converters (LCC) or voltage sourced converter (VSC) technology and it is from these projects that most examples of fires and fire incidents are taken. This technical report also addresses converter valves and valve halls for SVC and FACTS. This technical report provides general recommendations to be considered while preparing specifications for these systems. Specific requirements for a particular project need to be clearly specified and mutually agreed upon between the supplier and the purchaser. This consolidated version consists of the first edition (2015) and its amendment 1 (2019). Therefore, no need to order amendment in addition to this publication.
