Ububanzi bokusetshenziswa kwedivayisi ehlakaniphile yokucindezela i-arc:
1. Lo mshini ulungele uhlelo lwamandla kagesi aphakathi kuka-3 ~ 35KV;
2. Lezi zinsiza zifanele uhlelo lokuphakelwa kwamandla lapho indawo emaphakathi ingagxilile, indawo emaphakathi isekelwe ngekhoyili yokucindezela i-arc, noma indawo emaphakathi isekelwe ngenxa yokumelana okuphezulu.
3. Le mishini ifanele amagridi kagesi anezintambo njengomzimba oyinhloko, amagridi kagesi ayingxube anezintambo nezintambo eziphezulu njengomzimba oyinhloko, namagridi kagesi anezintambo eziphezulu njengomzimba oyinhloko.
Imisebenzi eyisisekelo yemishini ehlakaniphile yokucindezela i-arc:
1. Uma idivayisi isebenza ngokujwayelekile, inomsebenzi we-PT cabinet
2. Ngesikhathi esifanayo, inomsebenzi we-alamu yokunqanyulwa kwesistimu nokukhiya;
3. I-alamu yensimbi yesistimu ye-fault, i-alamu yokudlulisa i-ground fault point function;
4. Sula idivayisi yokumisa i-arc, umsebenzi we-software yochungechunge lwe-resonance;umsebenzi we-alamu ophansi we-voltage kanye ne-overvoltage;
5. Inemisebenzi yokurekhoda yolwazi njengesikhathi sokuqeda i-alamu yephutha, imvelo yephutha, isigaba sephutha, i-voltage yesistimu, i-voltage ye-delta evulekile yesifunda, i-capacitor ground current, njll., elungele ukuphathwa kwephutha nokuhlaziywa;
6. Uma isofthiwe yesistimu inephutha lesigaba esisodwa sokumisa, idivayisi ingaxhuma ngokushesha iphutha phansi phakathi kuka-30ms ngokusebenzisa isixhumi esikhethekile sokuhlukanisa isigaba.I-grounding overvoltage izinzile ezingeni le-voltage yesigaba, engavimbela ngempumelelo iphutha lesifunda esifushane elinemibala emibili elibangelwa ukumiswa kwesigaba esisodwa kanye nokuqhuma kwe-zinc oxide arrester okubangelwa i-arc grounding overvoltage.
7. Uma insimbi igxiliwe, i-voltage yokuxhumana kanye nesinyathelo se-voltage ingancishiswa kakhulu, okulungele ukuqinisekisa ukuphepha komuntu siqu (isisekelo sensimbi singasethwa ukuthi ngabe idivayisi isebenza ngokuvumelana nezidingo zomsebenzisi);
8. Uma isetshenziswa kugridi yamandla ikakhulukazi eyakhiwe imigqa ephezulu, isixhumi esingenasici sizovala ngokuzenzakalelayo ngemva kwamasekhondi angu-5 okusebenza kwedivayisi.Uma kuwukwehluleka kwesikhashana, isistimu izobuyela kokujwayelekile.Esimeni sokwehluleka unaphakade, idivayisi izophinda isebenze ukuze ikhawulele unomphela ukugcwala ngokweqile.
9. Uma kwenzeka iphutha lokunqanyulwa kwe-PT ohlelweni, idivayisi izobonisa umehluko wesigaba sephutha lokunqanyulwa futhi ikhiphe isignali yokuxhumana ngesikhathi esifanayo, ukuze umsebenzisi akwazi ukukhiya ngokuthembekile idivayisi yokuvikela engase yehluleke ngenxa yokunqanyulwa kwe-PT. .
10. Ubuchwepheshe bedivayisi obuyingqayizivele be-“intelligent socket (PTK)” bungacindezela ngokuphelele ukwenzeka kwe-ferromagnetic resonance, futhi buvikele ngempumelelo iplatinum ekushi, ekuqhumeni nakwezinye izingozi ezibangelwa ukukhala kwesistimu.
11. Lolu cingo lufakwe isokhethi le-RS485, futhi lwamukela iphrothokholi yokuxhumana ye-MODBUS ejwayelekile ukuze kuqinisekiswe imodi yokuhambisana phakathi kwedivayisi nawo wonke amasistimu okuqapha amavidiyo, nokugcina imisebenzi yokudluliswa kwedatha nesilawuli kude.
Imiyalo yoku-oda idivayisi ehlakaniphile yokucindezela i-arc
(1) Ikhasimende kufanele linikeze amandla kagesi alinganisiwe afanele ohlelo kanye namandla aphezulu amanje esigaba esisodwa sokubeka phansi se-capacitor yohlelo njengesisekelo sokuklanywa kwezinto zokusebenza;
(2) Ubukhulu bekhabhinethi bungaphothulwa kuphela ngemva kokuba onjiniyela bethu beklame futhi baqinisekisa ngesiginesha yomsebenzisi.
(3) Ikhasimende kufanele linqume imisebenzi yesisetshenziswa (kuhlanganise nezinto eziyisisekelo nemisebenzi eyengeziwe), lisayine uhlelo lobuchwepheshe oluhambisanayo, futhi libeke ngokucacile zonke izidingo ezikhethekile lapho lithenga.
(4) Uma ezinye izinsimbi ezengeziwe noma izingxenye ezisele zidingeka, igama, imininingwane kanye nenani lezingxenye ezisele ezidingekayo kufanele kukhonjiswe lapho ku-oda.
