GB/T 6115.2-2002 in English

《GB/T 6115.2-2002电力系统用串联电容器 第2部分:串联电容器组用保护设备》由TC45（全国电力电容器标准化技术委员会）归口，主管部门为中国电器工业协会。
GB /T 6 115的本部分适用于每相10M var以上的串联电容器组用的保护设备。保护设备是指串联电容器装置主回路中的器件和附属设备，它是串联电容器装置的一部分，但装于串联电容器外部。串联电容器部分的要求由GB/T 6115.1-1998给出，GB/T 6115.1-1998的1.3和7. 6提及保护设备。

Scope

This part of GB/T 6115 is applicable to the protective equipment for series capacitor banks with each phase above 10Mvar. Protection equipment refers to the devices and auxiliary equipment in the main circuit of the series capacitor device. It is a part of the series capacitor device, but it is installed outside the series capacitor. The requirements for series capacitors are given by GB/T 6115.1-1998, and 1.3 and 7.6 of GB/T 6115.1-1998 mention protective equipment. The protective equipment involved in this standard includes the following items: - overvoltage protector; - protective spark gap; - non-linear resistor (varistor); - bypass circuit breaker; - isolating switch; ——Current limiting damping equipment; ——Discharging reactor; ——Potential transformer; ——Current transformer; ——Signal column; ——Relay protection, control equipment and platform-ground communication equipment. see picture 1. Chapter 3 presents the principles involved in the use and operation of series capacitors. Examples of fault conditions are given in Chapter 3. Examples of wiring diagrams using different overvoltage protection principles are given in 2.1.
