Capacitors for high？voltage alternating current circuit？breakers - Part 2: TRV capacitors
文件核验信息（付费前可核对）
标准范围（官方英文摘要）
IEC 62146-2:2023 is applicable to TRV capacitors used on high-voltage alternating current circuit-breakers with rated voltages above 100 kV with 50 Hz or 60 Hz.
TRV capacitors are installed phase to earth, either in parallel to the bushing on dead tank circuit-breakers, or immersed inside the circuit-breaker, or freestanding close to the circuit-breaker. Their function is to limit the transient recovery voltage (TRV) and the rate of rise of recovery voltage (RRRV) on the circuit-breaker. Capacitors in compliance with this document can be used as TRV capacitor.
This document applies to TRV capacitors falling into one or both of the following categories for:
- mounting on or close to air insulated switchgear (AIS) dead tank and live tank circuit-breakers, or
- mounting on gas insulated switchgear (GIS) circuit-breakers.
The testing for each of the above applications is in some cases different.
This document does not apply to grading capacitors installed in parallel to the chambers of the circuit-breaker, which are specified in IEC 62146-1.
This document does not apply to capacitors not directly associated with high-voltage alternating current circuit-breakers.
