Isizathu sokuba kutheni i-iron idinga isiseko esincinci xa siqhelekile

Ngethuba lokusebenza okuqhelekileyo kwe-transformer, kukho intsimi yombane phakathi kwe-windings ephilayo kunye netanki, kunye nentsimbi yentsimbi kunye nezinye izinto zetsimbi kule ndawo yombane. Ngenxa yokusabalalisa okungalinganiyo kwe-capacitance kunye namandla ahlukeneyo entsimi, ukuba i-hose yensimbi kunye ne-hose yentsimbi yentsimbi yentsimbi ayinakusekwa, ukutshaja kunye nokukhutshwa kuya kwenzeka, okuya kutshabalalisa amandla okugquma kwe-insulation eqinile kunye neoli, ngoko ke umbindi wentsimbi kufuneka yiba nengongoma esekelwe kuyo.

Ingundoqo yentsimbi yenziwe ngamacwecwe ensimbi ye-silicon kunye nemibhobho yentsimbi kunye nemibhobho yensimbi engenasici. Ukuze kuncitshiswe imisinga ye-eddy, kukho ukuxhathisa okuthile phakathi kwamaphepha (ngokukodwa kuphela ii-ohm ezimbalwa ukuya kumashumi amaninzi e-ohms). Ithathwa njengendlela, ngoko ke inqaku elinye kuphela lokumisa kumbindi wentsimbi elinokuthi libambe amandla aso sonke isixa sombindi wentsimbi kwisakhono somhlaba.

Xa undoqo wentsimbi okanye amacandelo ayo esinyithi asekelwe kumanqaku amabini okanye ngaphezulu (i-multi-point), i-loop evaliweyo iya kwenziwa phakathi kweendawo zokumisa, kwaye i-magnetic flux ye-bond chain iya kubangela amandla e-electromotive kwaye yenze i-loop, ibangele. kwindawo Overheating lendawo kunye nokutshisa intsimbi core.

Inye kuphela inqaku le-transformer core lisekelwe, elisisiseko esiqhelekileyo. Oko kukuthi, i-hose yensimbi yentsimbi yentsimbi kufuneka ibekwe phantsi, kwaye kufuneka ibekwe kwinqanaba elinye.

Ukungaphumeleli kwe-iron kubangelwa ikakhulu zizizathu ezibini, enye isiphaluka esifutshane esibangelwa yinkqubo yolwakhiwo olubi, kwaye enye i-multi-point grounding ebangelwa yi-hose yentsimbi ye-stainless hose accessories kunye nezinto zangaphandle.

Ukulungisa iingxaki kwiimpazamo zomhlaba ezinamanqaku amaninzi

(1) Indlela yokuphelisa okwethutyana xa i-transformer ayikwazi ukuvalwa:

①Kukho ucingo olusezantsi lwangaphandle. Ukuba i-fault current inkulu, ucingo lomhlaba lunokuvulwa okwethutyana ukuze lusebenze. Nangona kunjalo, ukubekwa esweni kufuneka kuqiniswe ukuze kuthintelwe umbindi wentsimbi ekubonakaleni amandla adadayo emva kokuba indawo yempazamo ilahlekile.

② Ukuba i-multi-point grounding impazamo yohlobo olungazinzanga, ukuchasana kwe-wire sliding kunokudibaniswa kwichungechunge kunye nocingo olusebenzayo olusebenzayo ukukhawulela okwangoku ukuya ngaphantsi kwe-1A. Ukukhetha ukuchasana kwe-sliding wire kukwahlula i-voltage elinganisiweyo xa ucingo oluqhelekileyo olusebenzayo luvulwa kwaye lwahlulwe ngokukhoyo kwintambo yomhlaba.

③ Sebenzisa uhlalutyo lwechromatographic ukujonga izinga lokuvelisa igesi kwindawo yempazamo.

④ Emva kokufumana iphoso elichanekileyo ngokulinganisa, ukuba ayinakukwazi ukujongana nayo, isiqwenga esiqhelekileyo sokumisa isiseko sentsimbi sinokuhanjiswa kwindawo efanayo yecala lokunciphisa kakhulu umbane ojikelezayo.

(2) Gqibezela amanyathelo okuhlaziya. Emva kokubeka iliso kufumanise ukuba kukho i-multi-point grounding error in transformer, i-transformer enokuvalwa kufuneka ivalwe ngexesha, kwaye i-multi-point grounding iphoso kufuneka ikhutshwe ngokupheleleyo emva kokuphuma. Ukuphelisa ezo ziphoso, amanyathelo okugcinwa okuhambelanayo kufuneka athathwe ngokohlobo kunye nembangela ye-multi-point grounding. Nangona kunjalo, kwezinye iimeko, indawo ephosakeleyo ayinakufumaneka emva kokuba umbane umisiwe. Ukuze ufumane indawo yokumisa ngokuchanekileyo, iindlela ezilandelayo zingasetyenziswa kwisayithi.

① indlela yeDC. Vula iqhekeza lentsimbi engundoqo yentsimbi yombhobho wentsimbi kunye nesibambiso, kwaye ugqithise i-6V DC ukuya kwi-silicon sheet sheets kumacala omabini edyokhwe, emva koko usebenzise i-DC voltmeter ukulinganisa umbane phakathi kwawo onke amanqanaba e-silicon sheet sheet. ekujikeni. Xa i-voltage ilingana ne-zero okanye Xa isalathisi semitha siguqulwa, sinokuthathwa njengendawo yokubeka impazamo.

② indlela yonxibelelwano. Xhuma i-low-voltage winding ye-transformer kwi-voltage ye-AC ye-220 ~ 380V. Ngeli xesha, kukho i-flux yamagnetic kwi-hose yensimbi kunye ne-stainless steel hose kwi-iron core. Ukuba kukho iimpazamo ezininzi zomhlaba, sebenzisa i-milliammeter ukulinganisa okwangoku (i-iron core kunye ne-clamps). Isiqwenga sokudibanisa kufuneka sivulwe). Sebenzisa i-milliammeter ukulinganisa inqaku ngenqaku ecaleni kwedyokhwe yentsimbi kuwo onke amanqanaba. Xa i-current kwi-milliampere ingu-zero, yindawo ephosakeleyo.
