Cov qauv tseem ceeb hauv tsev rau lub tshuab nqus tsev Circuit Court breakers yog

JP3855-96 "Txhua yam kev mob rau 3.6-40.5kV AC High Voltage Vacuum Circuit Breakers"
DL403-91 "Technical Conditions for Ordering 10~35kV Indoor High Voltage Circuit Breakers"
Nws yuav tsum raug sau tseg tias tsis muaj cov qauv tshwj xeeb hauv IEC tus qauv uas sib haum rau Tuam Tshoj JB3855, tab sis tsuas yog siv "IEC56 AC High Voltage Circuit Breaker". Yog li ntawd, cov qauv rau lub tshuab nqus tsev vacuum breakers hauv Suav teb yog tsawg dua los yog nruj dua li IEC cov qauv hauv qab no:
(1) Rwb thaiv tsev theem: Test voltage IEC Tuam Tshoj
1min fais fab zaus tiv taus voltage (kV) 28 42 (ncej rau ncej, ncej rau hauv av) 48 (nruab nrab pob txha)
1.2/50 impulse withstand voltage (kV) 75 75 (ncej mus rau ncej, ncej rau hauv av) 84 (nruab nrab pob txha)
(2) Kev tiv thaiv hluav taws xob ntawm lub tshuab nqus tsev cuam tshuam tom qab kev ntsuas hluav taws xob ua tiav: tsis tau teev tseg hauv IEC56. Raws li cov kev cai ntawm JB3855-96 nyob rau hauv Suav teb, lub rwb thaiv tsev muaj peev xwm ntawm qhov tawg ntawm lub tshuab nqus tsev Circuit Court breakers tom qab ua tiav cov hluav taws xob lub neej xeem yuav tsum tsis txhob tsawg tshaj li 80% ntawm thawj theem rwb thaiv tsev, uas yog, lub zog zaus ntawm 1min 33.6kV thiab cuam tshuam ntawm 60kV.
(3) Kev sib cuag kaw thiab thaws lub sij hawm: IEC tsis muaj kev cai, thaum Tuam Tshoj txoj cai yuav tsum tsis pub tshaj 2ms.
(4) Kev ntsuas tam sim no rau qhov ntsuas kub nce: Hauv IEC tus qauv, qhov ntsuas tam sim no sib npaug rau qhov ntsuas tam sim no ntawm cov khoom. Qhov ntsuas tam sim no tau teev tseg hauv DL403-91 hauv Suav teb yog 110% ntawm qhov ntsuas tam sim no ntawm cov khoom.
2. Lub ntsiab technical parameters ntawm lub tshuab nqus tsev vacuum breakers tuaj yeem muab faib ua ob yam: kev xaiv thiab kev ua haujlwm tsis ua haujlwm. Cov qub yog siv los ntawm cov neeg siv khoom tsim thiab xaiv; Cov tom kawg yog hais txog cov yam ntxwv ntawm txhua yam lossis kinematic ntawm lub Circuit Court breaker nws tus kheej, uas yog cov cim qhia kev ua haujlwm thiab kev hloov kho.
