Imiyalelo yokuyalela ukucinezelwa kwe-arc kunye nesixhobo sokuphelisa i-harmonic

Umda wosetyenziso lwesixhobo socinezelo se-arc esikrelekrele:
1. Esi sixhobo sifanelekile kwi-3 ~ 35KV inkqubo yamandla ombane ophakathi;
2. Esi sixhobo sifanelekile kwisistim sombane apho indawo engathathi hlangothi ingagxilwanga, indawo engathathi hlangothi igxininiswe nge-coil yokucinezela i-arc, okanye indawo engathathi hlangothi isekelwe ngokuchasana okuphezulu.
3. Esi sixhobo sifanelekile kwiigridi zamandla kunye neentambo njengomzimba oyintloko, i-hybrid power grids kunye neentambo kunye neentambo eziphezulu njengomzimba oyintloko, kunye neegridi zamandla ezineentambo eziphezulu njengomzimba oyintloko.

Imisebenzi esisiseko yezixhobo ezikrelekrele zokucinezela i-arc:
1. Xa isixhobo sisebenza ngokuqhelekileyo, sinomsebenzi we-PT cabinet
2. Ngelo xesha, inomsebenzi we-alarm yokuqhawula inkqubo kunye nokukhiya;
3. Inkqubo yentsimbi yentsimbi ye-alarm yomhlaba, inkqubo yokudlulisa i-fault point function;
4. Sula isixhobo sokumisa i-arc, umsebenzi wenkqubo yesoftware ye-resonance;i-voltage esezantsi kunye nomsebenzi we-alarm overvoltage;
5. Inemisebenzi yokurekhoda yolwazi efana nexesha lokuphelisa i-alarm, i-fault nature, i-fault phase, i-voltage ye-system, i-voltage evulekile ye-delta voltage, i-capacitor ground current, njl., ekulungele ukuphatha iimpazamo kunye nokuhlalutya;
6. Xa isoftware yesistim inesiphambeko senqanaba elinye, isixhobo sinokudibanisa ngokukhawuleza impazamo emhlabeni malunga ne-30ms ngokusebenzisa i-splitting vacuum contactor ekhethekileyo.I-grounding overvoltage izinzile kwinqanaba le-voltage yesigaba, esinokuthi sithintele ngokufanelekileyo impazamo yesiphaluka esifutshane semibala emibini ebangelwa yi-single-phase grounding kunye nokuqhuma kwe-zinc oxide arrester okubangelwa yi-arc grounding overvoltage.
7. Ukuba isinyithi sisekelwe, i-voltage yoqhagamshelwano kunye ne-voltage yesinyathelo ingancitshiswa kakhulu, ehambelana nokuqinisekisa ukhuseleko lomntu (i-metal grounding ingamiselwa ukuba isixhobo sisebenza ngokweemfuno zomsebenzisi);
8. Ukuba isetyenziswe kwigridi yamandla ehlanganiswe ikakhulu yimigca ephezulu, i-vacuum contactor iya kuvala ngokuzenzekelayo emva kwemizuzwana emi-5 yokusebenza kwesixhobo.Ukuba kukungaphumeleli okomzuzwana, inkqubo iya kubuyela kwimeko yesiqhelo.Kwimeko yokungaphumeleli okusisigxina, isixhobo siya kusebenza kwakhona ukukhawulela ngokusisigxina ukugqithisa.
9. Xa impazamo ye-PT yoqhawulo lwenzeka kwisixokelelwano, isixhobo siya kubonisa umahluko wesigaba sempazamo yoqhagamshelo kunye nokukhupha isignali yoqhagamshelwano ngexesha elinye, ukuze umsebenzisi akwazi ukutshixa ngokuthembekileyo isixhobo sokhuseleko esinokusilela ngenxa yoqhagamshelo lwe-PT. .
10. Ubuchwephesha besixhobo obubodwa “besokethi esikrelekrele (i-PTK)” bunokucinezela ngokupheleleyo ukwenzeka kweresonance ye-ferromagnetic, kwaye bukhusele ngokufanelekileyo iplatinam ekutshisweni, ugqabhuko-dubulo kunye nezinye iingozi ezibangwa kukurhawuka kwenkqubo.
11. Isixhobo sixhotyiswe ngesokethi ye-RS485, kwaye samkela iprothokholi yonxibelelwano yeMODBUS esemgangathweni ukuqinisekisa imowudi yokuhambelana phakathi kwesixhobo kunye nazo zonke iinkqubo zokucupha ividiyo, kunye nokugcina imisebenzi yokuhanjiswa kwedatha kunye nolawulo olukude.

Imiyalelo yoku-odola isixhobo esikrelekrele sokucinezela i-arc
(1) Umthengi kufuneka abonelele ngevoltheji efanelekileyo yenkqubo kunye nowona mkhulu wangoku wesigaba esinye secapacitor yokumisa inkqubo njengesiseko soyilo lwesixhobo;
(2) Ubungakanani bekhabhinethi bunokugqityezelwa kuphela emva kokuba iinjineli zethu ziyilo kwaye ziqinisekise ngokutyikitya komsebenzisi.
(3) Umthengi kufuneka anqume imisebenzi yezixhobo (kubandakanywa izinto ezisisiseko kunye nemisebenzi eyongezelelweyo), asayine isicwangciso sobugcisa esihambelanayo, kwaye abeke ngokucacileyo zonke iimfuno ezikhethekileyo xa kuthengwa.
(4) Ukuba ezinye izincedisi ezongezelelweyo okanye iinxalenye ezisecaleni ziyafuneka, igama, iinkcukacha kunye nobungakanani beendawo eziyimfuneko kufuneka ziboniswe xa kuodolwa.
