Uhlobo lwe-cuout fuse:
I-fuse yohlobo lwe-drop-type iyona nto isetyenziswa ngokuqhelekileyo i-short-circuit yokukhusela imigca yesebe ye-10kV imigca yokuhambisa kunye nokusabalalisa i-transformers.Ineempawu zoqoqosho, ukusebenza ngokufanelekileyo, ukuguquguquka okuqinileyo kwimeko yangaphandle kunye nokunye.Isetyenziswa ngokubanzi kwicala eliphambili le-10kV imigca yokuhambisa kunye nokusabalalisa ukuguqulwa kokukhusela kunye nokutshintsha izixhobo kunye nokusebenza kokusika.
Ifakwe kumgca wesebe we-10kV wokusabalalisa umgca, onokunciphisa umda wokungaphumeleli kwamandla.Ngenxa yendawo ecacileyo yokuqhawula i-fuse ye-high-voltage drop-type fuse, inomsebenzi wokutshintsha ukwahlula, okwenza indawo yokusebenza ekhuselekileyo yomgca wokulondoloza kunye nezixhobo, kunye nokwandisa ingqiqo yokhuseleko lwabasebenzi bokulondoloza. i-transformer yokusabalalisa, inokusetyenziswa njengokhuseleko oluphambili lwe-transformer yokusabalalisa, ngoko ke iye yaziwa kakhulu kumgca wokusabalalisa we-10kV kunye nokusabalalisa i-transformer.
Ukufakelwa kohlobo lwe-drop-type fuse:
(1) ngexesha lofakelo, ukunyibilika kufuneka kuqiniswe (ukuze inyibilike ibe malunga noxinzelelo lwe-24.5N), ngaphandle koko kulula ukubangela ukushisa kweenwele.
(2) i-fuse iya kumiswa ngokuthembekileyo nangokuthembekileyo kwi-crossarm (isakhelo) ngaphandle kokungcangcazela okanye ukungcangcazela.
(3) umbhobho otyhidiweyo kufuneka ube neEngile ezantsi engama-25° ±2°, ukuze umbhobho otyhidiweyo uwe ngokukhawuleza ngokobunzima bawo xa inyibilika idityaniswa.
(4) i-fuse iya kufakwa kwingalo enqamlezileyo (isakhelo) kunye nomgama othe nkqo ongekho ngaphantsi kwe-4m ukusuka emhlabeni.Ukuba ifakwe ngaphezu kwe-transformer yokusabalalisa, umgama othe tye phakathi kwe-fuse kunye nomda we-contour wangaphandle we-transformer uya kugcinwa kumgama ongaphezu kwe-0.5m, kwimeko yezinye iingozi ezibangelwa ukuhla kwe-fuse.
(5) ubude be-fuse buya kulungelelaniswa kwinqanaba eliphakathi.Kuyafuneka ukuba ulwimi lomlomo wedada lukwazi ukubamba ngaphezulu kwesibini kwisithathu sobude boqhagamshelwano emva kokuvala, ukuze kuthintelwe isenzo esingalunganga sokuziwisa xa sisebenza.
(6) inyibiliko esetyenzisiweyo kufuneka ibe yimveliso eqhelekileyo yabenzi besiqhelo, kwaye ibe namandla athile omatshini, iimfuno jikelele zokunyibilika zinokumelana ubuncinane ne-147N ngaphezu koxinzelelo.
(7) I-10kV yodidi lwe-drop-type fuse iya kufakwa ngaphandle kwaye umgama we-interphase uya kuba mkhulu kune-70cm.
Ukusebenza kohlobo lwe-drop-type fuse:
Kwiimeko eziqhelekileyo, akuvumelekanga ukusebenzisa i-fuse ye-drop kunye nomthwalo, vumela kuphela ukuba isebenzise izixhobo ezingenayo umthwalo (umgca) .Nangona kunjalo, i-transformers yokusabalalisa kunye nomthamo olinganisiweyo ongaphantsi kwe-200kVA kunye nemigca yesebe ye-10kV yokusabalalisa imigca kuthungelwano lwezolimo. bavunyelwe ukusebenza phantsi komthwalo ngokwezi mfuno zilandelayo:
(1) umsebenzi uya kwenziwa ngabantu ababini (umntu omnye wolongamelo kunye nomntu omnye wokuqhuba), ngaphandle kokuba baya kunxiba iiglavu zokhuselo olufanelekileyo, iibhutsi zokugquma kunye nezibuko, kwaye basebenze ngeentonga zokhuselo ezisemgangathweni ezinemigangatho yombane ehambelanayo.Ukusebenza akuvumelekanga kwimozulu yombane okanye imvula enkulu.
(2) xa utsala umsebenzi wokuqhawula, ngokuqhelekileyo umiselwe ukutsala isigaba esiphakathi kuqala, emva koko isigaba se-leeward, kwaye ekugqibeleni isigaba secala lomoya. Oku kungenxa yokuba i-transformer yokusabalalisa ukusuka kwisigaba sesithathu ukuya kwisigaba sesibini - ukusebenza kwesigaba, tsala isigaba esiphakathi esiveliswe yintlantsi ye-arc encinci, ayiyi kubangela isiphaluka esifutshane phakathi.Okwesibini kukwaphula isigaba se-leeward side, kuba isigaba esiphakathi sitsaliwe, isigaba se-leeward side kunye nomgama wesigaba somoya siphindwe kabini, nokuba kukho i-overvoltage, okubangela ukuba isiphaluka esifutshane phakathi kwezinto ezinokwenzeka sincinci kakhulu.Ekugqibeleni, xa isigaba se-upwind sitsalwa, kuphela i-capacitive current emhlabeni, i-spark ebangelwayo ibe yinto encinci kakhulu.
(3) xa iswitshi ivaliwe, ulandelelwano lomsebenzi lubuyiselwa umva xa iswitshi itsalwa.Okokuqala, i-upwind side phase ivaliwe, emva koko i-leeward side phase ivalwe, kwaye ekugqibeleni isigaba esiphakathi sivaliwe.
(4) ukusebenza kombhobho otyhidiweyo kuyiprojekthi eqhelekileyo.Ukuba awuyikunikela ingqalelo kuyo, kuya kubangela ukuvutha koqhagamshelwano kwaye kukhokelela kuqhagamshelwano olubi.Uqhagamshelwano luya kutshisa kakhulu kwaye intwasahlobo iya kuhlanjululwa.Ngoko, tsala, uvale ityhubhu yokunyibilika ukunyanzelisa ngokuphakathi, uvale kakuhle, ukukhangela ngononophelo ulwimi lungakwazi ukubopha ulwimi ngolwimi kwisibini kwisithathu sobude obungasentla, unokutsala. i-brake bar hook emlonyeni wedada ukucinezela phantsi amaxesha ambalwa, uze uzame ukutsala, khangela ukuba kulungile.Ukungaphumeleli ukuvala iswitshi endaweni okanye ukuvala ngokuqinileyo, uqhagamshelwano olusisigxina kuxinzelelo lwe-fuse akwanelanga, kulula ukubangela ukutshisa koqhagamshelwano okanye ityhubhu enyibilikayo iwe
