The terms and definitions as defined in GB/T 2900.13-2008, GB/T 2900.18-
2008, GB/T 5080 (all parts), GB 10963.1-2005, GB 10963.2-2008, GB 14048.1-
2012, GB 14048.2-2008, GB 14048.4 -2010, GB 14048.5-2008, GB 14048.6-
2008, GB 16916.1-2014, GB 16917.1-2014 and the following apply to this
document.
3.1.1
Reliability
It refers to the ability of the product to complete the specified function within
the specified conditions and within the specified time.
3.1.2
Failure rate
It refers to the probability of failure of the product within the unit time after
working to the time t.
3.1.3
success ratio, the residual current protection success ratio after the
environmental test, the short circuit protection success ratio, and the overload
protection success ratio as the reliability characteristic quantity.
4.1.2 Reliability leveling of the residual current operated circuit breakers
for household and similar purposes
It respectively uses the operation failure rate level, the residual current
protection success ratio, the success ratio of the residual current protection
after the environmental test, the short circuit protection success ratio, and the
overload protection success ratio as the reliability indicators.
Based on the value of the maximum failure rate λmax, the operation failure rate
level is divided into four levels (level 4, sub-level 4, level 3, and sub-level 3).
Based on the value of the unacceptable success ratio R1, the residual current
protection success ratio is divided into four levels (level 6, level 5, level 4, and
level 3), the success ratio of residual current protection after the environmental
test is divided into four levels (level 6, level 5, level 4, and level 3), the short
circuit protection success ratio is divided into four levels (level 6, level 5, level
4, and level 3), AND the overload protection success ratio is divided into four
levels (level 5, level 4, level 3, and level 2).
4.2 Reliability indicators for overcurrent protection circuit breakers for
household and similar purposes
4.2.1 Reliability characteristic quantity of overcurrent protection circuit
breakers for household and similar purposes
The overcurrent protection circuit breaker for household and similar purposes
uses the operation failure rate (λ), the short-circuit protection success ratio, and
the overload protection success ratio as its reliability characteristic quantity.
4.2.2 Reliability leveling of overcurrent protection circuit breakers for
household and similar purposes
It respectively uses the operation failure rate level, the short-circuit protection
success ratio level, and the overload protection success ratio as the reliability
indicators.
Based on the value of the maximum failure rate λmax, the operation failure rate
level is divided into four levels (level 4, sub-level 4, level 3, and sub-level 3).
