Njira ndi njira yowonera ulendo ndi kutsekanso kulephera kwa air circuit breaker(ACB)

Air circuit breaker(ACB) kupunthwa, kutsekanso kwalephera

1. Choyamba dziwani ngatiAir circuit breakersichinagwe mwangozi

Ulendo wopanda ngozi umatanthauza ulendo wopanda dera lalifupi kapena vuto lodzaza.Pali zifukwa zambiriAir circuit breakerosati kutseka.Choyamba, m'pofunika kudziwa ulendo chifukwa yochepa dera ndi mochulukira, kapenaair circuit breakeryokha kapena loop yowongolera ndiyolakwika.Pezani ndikuwona ngati deralo ndi lolakwika kapena ayichowotcha mpweyapalokha ndi yolakwika.
Pambuyo pozindikira vuto la wophwanyira mpweya, jambulani chophwanyira dera (amatanthawuzadrawer mtundu air circuit breaker) kuti awonedwe.

2. Universal mtundu circuit breaker wamba kukonza vuto

(1) Wowononga dera sangathe kutsekedwa chifukwa cha kutaya mphamvu mu chipangizo chopanda mphamvu.Ngati voteji ndi yotsika kwambiri kapena koyilo ya chipangizo chodumphira chopanda mphamvu yatha mphamvu, chophwanya dera chidzayenda ndipo sichingatsekenso.Zinthu zinayi zotsatirazi zitha kupangitsa kuti koyilo ya tripper ya undervoltage kutaya mphamvu.

• (1) Fuseti yoteteza dera imawombedwa, monga RT14, zomwe zimapangitsa kutsekeka kwa dera ndi kutaya mphamvu kwa coil yodumphadumpha ya chipangizo chopanda mphamvu;
• (2) batani lapafupi, kukhudzana ndi ma relay, cholumikizira chothandizira kukhudzana ndi mutu woyipa, kuwonongeka kwa gawo, kungayambitse kutsekeka kwa dera, kutayika kwa mphamvu ya koyilo;
• (3) Chingwe cholumikizira mu chipikacho chimasweka, ndipo phula la crimping ndi lotayirira komanso lotayirira, lomwe limapangitsanso kuti dera likhale lotsekedwa, ndipo koyilo yodutsa imachotsedwa;
• (4) Chifukwa cha koyilo ya kumasulidwa kwa undervoltage ndikugwira ntchito kwamagetsi kwa nthawi yayitali, kuipitsidwa kwa chilengedwe ndi zida sizingasinthe, kapena kusiyana kwa mpweya pakati pa pachimake ndi zida ndi zazikulu kwambiri, ndizosavuta pangani kuchuluka kwamakono ndikupangitsa kuti koyiloyo ikhale yotentha komanso kuyaka, kutaya ntchito ya koyilo yotulutsa.
• Cholakwika chomwe chili pamwambapa kudzera mukuyang'ana ndi kuyang'ana kosavuta ndi kuyesa kungathe kupanga chigamulo cholondola, choncho chikapezeka cholakwika chiyenera kuthetsedwa mu nthawi, monga kukhudzana kotayirira kuti kumangidwe, kuwonongeka kwa chigawo ndi kuyatsa koyilo komwe kumayenera kusinthidwa.

(2) Kulephera kwa makina opangira makina, zomwe zimapangitsa kuti wothamanga wa dera sangathe kutseka. Pambuyo poyendetsa ndi kutseka makina ogwiritsira ntchito magetsi nthawi zambiri, makinawo amavala kwambiri ndipo zolakwa zotsatirazi zikhoza kuchitika.

• (1) Motor kufala limagwirira ntchito kuvala, monga ME switch nyongolotsi giya, mphutsi kuwonongeka, sangathe kuyendetsa wosweka dera opaleshoni limagwirira changa, kutseka.Zida za mphutsi, m'malo mwa nyongolotsi zimakhala zovuta kwambiri, kufunikira kwa akatswiri.
• (2) kuvala kwa makina oyenda kwaulere, kotero kuti wophwanya dera ndi wovuta kumangirira, kugwedezeka mosavuta, nthawi zina amakakamizika kumanga, ngati kugwedezeka, ulendo;Nthawi zina pambuyo pa buckle, chotchinga chotsekedwa chimatsika.Panthawiyi, wononga wononga kuyenera kuzunguliridwa kuti isinthe malo omwe amadumphira theka la shaft ndi chingwe chodutsa, kuti malo okhudzidwawo akhale pafupifupi 2.5mm2, ndipo mbali zofananira ziyenera kusinthidwa ngati kuli kofunikira.
• (3) Kasupe wosungira mphamvu wa makina ogwiritsira ntchito ndi olakwika.Kusweka kosungirako mphamvu kasupe wa makina ogwiritsira ntchito kumamasula kapena kutaya mphamvu yake pambuyo pa maulendo ambiri, ndipo mphamvu yotseka imakhala yochepa.Potseka, makina anayi oyendetsa dera sangathe kukankhidwira kumalo akufa, ndipo makinawo sangathe kudzisunga okha pamalo otseka.Choncho, wowononga dera sangathe kutsekedwa bwinobwino.Chitsime chosungira chiyenera kusinthidwa.
• (4) Njira yogwiritsira ntchito sikusintha, ndipo pali chodabwitsa chokhazikika.Chifukwa mtundu uwu wa wosweka dera si mokwanira anatsekeredwa, ngati zomangira, mtedza ndi matupi ena akunja mwangozi anasiyidwa mu limagwirira ntchito, kuti wosweka dera ntchito munakhala chodabwitsa, zingakhudze kutseka;Komanso, kasinthasintha ndi kutsetsereka mbali alibe mafuta mafuta, kutsegula mphamvu yosungirako kasupe wa limagwirira ntchito ndi wopunduka pang'ono, ndi wosweka dera sangathe kutseka ananyema.Choncho, pamene kulephera pamwamba kumachitika, kuwonjezera pa kuyang'ana makina ogwiritsira ntchito, palibe kusiyana, komanso kulowetsa mafuta odzola mu kasinthasintha ndi kutsetsereka gawo.
