Cov txheej txheem & xeem rau SF6 Circuit Breaker

* Kev tshuaj xyuas lub cev
1. Cov kab hluav taws xob raug
2. Tshawb xyuas kev puas tsuaj rau
Tswj cubical & Cheebtsam
Lub cev loj
3. Kev pab cuam ntawm CB rau tag nrho peb Phase

* Kev kuaj hluav taws xob
1. Rwb thaiv tsev Resistance Test
Rwb thaiv tsev tiv thaiv ntawm Phase mus rau hauv av & Theem mus rau Theem thaum CB nyob rau hauv qhov chaw kaw
Rwb thaiv tsev tsis kam ntawm Phase rau Ncej thaum CB nyob rau hauv Txoj Haujlwm Qhib
Siv 5kV DC rau 1 feeb rau kev ntsuas kev tiv thaiv hluav taws xob & tus nqi yuav tsum siab dua 100Mohms

2. Tsis kam ntawm Kaw & Tripping kauj
Kev ua haujlwm ntawm kev kaw & tripping kauj yog tsim nyog los xam & nws yuav qhia txog kev noj qab haus huv ntawm ob lub coils.

3. Tam sim no rau Kaw & Tripping Chev
Xam cov tam sim no rau tripping thiab kaw lub kauj thaum ua haujlwm ob qho tib si.

4. Breaker Mechanism
. Txheeb xyuas phau ntawv ua haujlwm ntawm CB & nws yuav tsum yog Ok
. Cov xwm txheej Breaker yuav tsum raug

5. Caij nplooj ntoos hlav Charge Motor Tam sim no ntsuas & sij hawm
. Xam qhov pib & Khiav Tsav tam sim no ntawm Nominal Voltage & Zaus tus nqi
. Tsis tas li ntawd, xam lub caij nplooj ntoos hlav them nqi rau CB thiab nws yuav tsum ua raws li FAT daim ntawv qhia.

6. Circuit Breaker Timing Test rau Ntau qhov kev tawm tswv yim Voltage
Breaker Trip Timing yog qhov kev ntsuam xyuas tseem ceeb tshaj plaws rau CB vim tias txhua lub sijhawm tshem tawm qhov txhaum yog ncaj qha ntsig txog lub sijhawm mus ncig ntawm CB. Txhawm rau xam lub CB kaw & lub sij hawm tripping siv ntau qhov input voltage li 80V, 100V, 120V, 140V thiab lwm yam, thiab ntsuas qhov tshwm sim & nws yuav tsum yog raws li FAT daim ntawv qhia & sib npaug ntawm tus nqi rau txhua qhov voltage ranges.
Muaj ob peb kauj ruam uas yuav tsum tau ua raws li kev suav ntawm kev kaw & lub sij hawm tripping rau CB.
. Ntsuas lub sijhawm kaw CB rau txhua qib voltage
. Ntsuas lub CB tripping lub sij hawm rau tag nrho cov voltage theem ob qho tib si ntawm Trip Circuit 1 & Trip Circuit 2 raws li
. Ntsuas lub CB Kaw-Qhib lub sijhawm ntawm nominal voltage theem ob qho tib si los ntawm Trip Circuit 1 & Trip Circuit 2 raws li
. Ntsuas lub CB Qhib-kaw lub sij hawm ntawm nominal voltage theem ob qho tib si ntawm Trip Circuit 1 & Trip Circuit 2 feem.
