IEC 62146-1 ED2

Capacitors for high-voltage alternating current circuit-breakers - Part 1: General and grading capacitors

Апстракт

This part of IEC 62146 includes generalities of capacitors used on alternating current circuit-breakers and introduces specifications for grading capacitors. Regarding grading capacitors, their function is to control the voltage distribution across the individual interrupter units of a multi-break circuit-breaker.

This document applies to grading capacitors falling into one or both of the following categories for:

mounting on air-insulated circuit-breakers.
mounting on enclosed circuit-breakers (for example immersed in insulating gas, in oil, etc.).

The object of this document is:

to define uniform rules regarding performances, testing and rating;
to define specific safety rules;
to provide a guidance for installation and operation.

This document does not apply to capacitors not directly associated with high-voltage alternating current circuit-breakers.
