Scope

NB/T 42065-2016 is the English-translated version of 真空断路器容性电流开合老炼试验导则.

NB/T 42065-2016 is a recommended Chinese energy industry standard that guides the capacitive current switching conditioning test of vacuum circuit-breakers.

It states the test requirements, the test methods, the characteristics of the test circuit and the treatment of the test results for the ageing test in which a vacuum circuit-breaker makes and breaks capacitor bank current.

It applies to vacuum circuit-breakers rated 7.2 kV to 40.5 kV at 50 Hz that have to switch capacitor bank current, and vacuum load switches and vacuum contactors used for the same duty may follow it as a reference.

The Chinese classification is K43 and the international classification 29.120.60. It cites GB 1984-2014, GB/T 2900.20-2016, GB/T 4473-2008 and GB/T 14549. Issued on 7 January 2016, it has applied since 1 June 2016.
