GB/T 7330-2008 in English

《GB/T 7330-2008交流电力系统阻波器》由TC82（全国电力系统管理及其信息交换标准化技术委员会）归口，主管部门为中国电力企业联合会。
本标准代替ＧＢ／Ｔ７３３０―１９９８《交流电力系统阻波器》本标准规定了有关阻波器的定义、工作条件、要求、试验和推荐值。本标准适用于串接于高压和超高压交流电力线中的阻波器。本标准不适用于为其他目的在高压电力线上的电感器以及用于交直流换流站的阻波器。本标准与ＧＢ／Ｔ７３３０―１９９８ 比较，在格式及技术内容方面，原ＧＢ／Ｔ７３３０―１９９８ 基本保留了ＩＥＣ６０３５３：１９９８的格式及其技术内容，而在本版中做了较大改动，还增加了附录Ｃ。此外，在文字和图的细节上也作了一些修改。

Scope

This standard specifies the definition, working conditions, requirements, tests and recommended values of wave traps. This standard applies to wave traps connected in series in high-voltage and extra-high-voltage AC power lines. The device is used to prevent excessive loss of carrier signals with frequencies generally in the range of 40 kHz to 500 kHz under various conditions of the power system, and to minimize interference from adjacent carriers. This standard does not apply to inductors on high-voltage power lines for other purposes and wave traps for AC-DC converter stations. See Appendix A for relevant information on wave traps used in AC/DC converter stations.
