Visokonapetostne stikalne in krmilne naprave - 100. del: Izmenični odklopniki (IEC 62271-100:2008/A1:2012 (EQV) + corrigendum Dec. 2012)
Ta del standarda IEC 62271 se uporablja za izmenične odklopnike za notranjo in zunanjo namestitev, ki delujejo na frekvencah 50 Hz in 60 Hz v sistemih z napetostjo, višjo od 1000 V. Uporablja se samo za tripolne odklopnike v trifaznih sistemih in enopolne odklopnike v enofaznih sistemih. O uporabi dvopolnih odklopnikov v enofaznih sistemih in pri frekvencah, nižjih od 50 Hz, se dogovorita proizvajalec in uporabnik. Ta standard se uporablja tudi za upravljalne naprave za tokovne odklopnike in njihovo pomožno opremo. Vendar ta standard ne zajema odklopnika z zapiralnim mehanizmom za odvisno ročno upravljanje, saj ni mogoče določiti naznačenega toka, ki povzroča kratki stik, pri čemer je lahko odvisno ročno upravljanje vprašljivo zaradi varnosti. Pravila za odklopnike z namerno nesočasnostjo med poli so v obravnavi; odklopniki z enopolnim samodejnim ponovnim vklopom so zajeti v tem standardu.

Add, between the existing first and second paragraphs of this subclause, the following new
paragraph:
62271-100 Amend.1 © IEC:2012 – 5 –
For circuit-breakers with rated voltages higher than 800 kV, the standard d.c. time constant is

current for 50 Hz and 60 Hz.

Replace the existing text and note of this subclause by the following new sentence:
Subclause 4.7 of IEC 62271-1 is applicable.
4.101.2 DC time constant of the rated short-circuit breaking current
Replace the existing text before Note 1 by the following new text:
a) For circuit-breakers with rated voltages up to and including 800 kV
The standard d.c. time constant is 45 ms. The following are special case d.c. time
constants, related to the rated voltage of the circuit-breaker:
– 120 ms for rated voltages up to and including 52 kV;
– 60 ms for rated voltages from 72,5 kV up to and including 420 kV;
– 75 ms for rated voltages 550 kV and 800 kV.
These special case time constants recognise that the standard value may be inadequate
in some systems. They are provided as unified values for such special system needs,
taking into account the characteristics of the different ranges of rated voltage, for example
their particular system structures, design of lines, etc.
Add, after the existing Note 3, the following new text:
b) For circuit-breakers with rated voltages higher than 800 kV
The standard d.c. time constant is 120 ms. Note 3 is also applicable in this case.
4.102.1 Representation of TRV waves
Replace the existing seventh and eighth paragraphs of this subclause by the following new
paragraphs:
If a circuit-breaker with a rated voltage equal to or less than 800 kV has a short-line fault
rating, the ITRV requirements are covered if the short-line fault tests are carried out using a
line with a time delay less than 100 ns (see 6.104.5.2 and 6.109.3) unless both terminals are
not identical from an electrical point of view (for instance when an additional capacitance is
used as mentioned in Note 4 of 6.109.3). When terminals are not identical from an electrical
point of view, test circuits which produce an equivalent TRV stress across the circuit-breaker
may be used.
For circuit-breakers with a rated voltage higher than 800 kV, the ITRV requirements are
considered to be covered if the short-line fault tests are carried out using a line with a time
delay less than 100 ns and a surge impedance of 450 Ώ unless both terminals are not
identical from an electrical point of view (for instance when an additional capacitance is used
as mentioned in Note 4 of 6.109.3). When terminals are not identical from an electrical point
of view, test circuits which produce an equivalent TRV stress across the circuit-breaker may
be used.
Since the ITRV is proportional to the busbar surge impedance and to the current, the ITRV
requirements can be neglected for all circuit-breakers with a rated short-circuit breaking
current of less than 25 kA and for circuit-breakers with a rated voltage below 100 kV. In
addition the ITRV requirements can be neglected for circuit-breakers installed in metal
enclosed gas insulated switchgear (GIS) because of the low surge impedance. ITRV
– 6 – 62271-100 Amend.1 © IEC:2012
requirements can also be neglected for circuit-breakers directly connected to a busbar with a
total source side capacitance of more than 800 pF.
4.102.2 Representation of TRV
Replace the existing item a) by the following new item a):
a) Four-parameter reference line (see Figure 10):
u = first reference voltage, in kilovolts;
t = time to reach u , in microseconds;
1 1
u = second reference voltage (TRV peak value), in kilovolts;

t = time
