Isizathu sokuba isiseko sentsimbi sidinga ukugalelwa kancinci xa siqhelekile

Ngexesha lokusebenza okuqhelekileyo kwe-transformer, kukho intsimi yombane phakathi kwee-live windings kunye netanki, kwaye i-iron core kunye nezinye izinto zesinyithi zikwintsimi yombane. Ngenxa yokusasazwa okungalinganiyo kwe-capacitance kunye namandla ahlukeneyo entsimi, ukuba i-metal hose kunye ne-stainless steel hose ye-iron core ayinakugaywa, kuya kubakho ukutshaja nokukhupha, okuya kutshabalalisa amandla okufaka i-insulation ye-solid insulation kunye ne-oyile, ngoko ke i-iron core kufuneka ibe nenqaku elinokubekwa i-insulation.

Umbindi wesinyithi wenziwe ngamashiti esinyithi e-silicon kunye neepayipi zesinyithi kunye neepayipi zentsimbi engagqwaliyo. Ukuze kuncitshiswe imisinga ye-eddy, kukho ukumelana okuthile kobushushu phakathi kwamaphepha (ngokuvamile ii-ohms ezimbalwa ukuya kwishumi lee-ohms). Ithathwa njengendlela, ngoko ke inqaku elinye kuphela lokumisa kwisiseko sesinyithi elinokuthintela amandla e-stack yonke ye-iron core laminations kwi-ground potential.

Xa umbindi wesinyithi okanye izinto zayo zesinyithi zisekelwe kwiindawo ezimbini okanye ngaphezulu (iingongoma ezininzi), kuya kwenziwa umjikelo ovaliweyo phakathi kweendawo zokumisa umhlaba, kwaye ukuhamba kwemagnethi kwekhonkco lebhondi kuya kubangela amandla e-electromotive kwaye kwenze umjikelo, nto leyo ekhokelela kwi-local Overheating kunye nokutshisa umbindi wesinyithi.

Ingongoma enye kuphela yesiseko se-transformer esekwe phantsi, nto leyo eqhelekileyo. Oko kukuthi, ipayipi yesinyithi yesiseko sesinyithi kufuneka isekwe phantsi, kwaye kufuneka ibekwe phantsi kwindawo enye.

Ukusilela kwe-iron core kubangelwa ikakhulu zizizathu ezibini, esinye si-short circuit ebangelwa yinkqubo yokwakha embi, kwaye esinye si-multi-point grounding ebangelwa yi-metal hose stainless steel hose accessories kunye nezinto zangaphandle.

Ukufunyanwa kweziphene zomhlaba ezinamanqaku amaninzi

Indlela yokugweba impazamo yokumisa isiseko sentsimbi eneendawo ezininzi idla ngokufunyanwa kwiinkalo ezimbini:

(1) Yenza uhlalutyo lwe-chromatographic yegesi. Kuhlalutyo lwe-chromatographic, ukuba umxholo we-methane kunye ne-olefin kwigesi uphezulu, kwaye umxholo we-carbon monoxide kunye negesi ye-carbon dioxide awutshintshi kakhulu xa kuthelekiswa nexesha elidlulileyo, okanye umxholo uqhelekile, oko kuthetha ukuba umongo wesinyithi ushushu kakhulu kwaye umongo wesinyithi ushushu kakhulu. Ubushushu obugqithisileyo bunokubangelwa kukugalelwa kwiindawo ezininzi.

Xa kwavela igesi ye-acetylene kuhlalutyo lwe-chromatographic, kwabonisa ukuba umongo wesinyithi wawune-intermittent multi-point grounding.

(2) Linganisa ukuba kukho umbane kwintambo yokumisa umhlaba. Ungasebenzisa imitha yokubamba ukulinganisa ukuba kukho umbane kwintambo yokumisa umhlaba ye-grounding bushing ngaphandle kwe-transformer core. Xa i-transformer core iqhele ukuba phantsi komhlaba, akukho luphu lwangoku olwenziwayo. Ukumisa umhlaba Umbane kumgca mncinane kakhulu, kwinqanaba le-milliamp (ngokubanzi ungaphantsi kwe-0.3A). Xa kukho iindawo ezininzi zokumisa umhlaba, kukho ukujika kwesekethe emfutshane ujikeleze i-magnetic flux ephambili ye-iron core, kunye nomsinga ojikelezayo ojikelezayo kwi-turn, kwaye ixabiso lawo lixhomekeke kwindawo yempazamo kunye nendawo ehambelana nendawo yesiseko eqhelekileyo, oko kukuthi, ubungakanani be-magnetic flux evalelwe kwi-short-circuit turn. Ngokubanzi, inokufikelela kumashumi aliqela e-amperes. Ngokulinganisa ukuba kukho umbane kwi-grounding lead, kuchanekile kakhulu ukumisela ukuba kukho umbane we-multi-point grounding fault kwi-iron core.

Ukusombulula iingxaki zeengxaki zomhlaba ezinamanqaku amaninzi

(1) Indlela yokususa okwethutyana xa i-transformer ingenakucinywa:

①Kukho ucingo olungaphandle lomhlaba. Ukuba umsinga wesiphako mkhulu, ucingo oluphantsi komhlaba lungavulwa okwethutyana ukuze lusebenze. Nangona kunjalo, kufuneka kuqiniswe ukubekwa esweni ukuze kuthintelwe ukuba intsimbi ingabonakali inamandla okudada emva kokuba indawo yesiphako inyamalale.

②Ukuba i-multi-point grounding fault ayizinzanga, i-sliding wire resistance ingadityaniswa ngochungechunge kunye ne-working ground wire ukunciphisa i-current ibe ngaphantsi kwe-1A. Ukhetho lwe-sliding wire resistance kukwahlula i-voltage elinganisiweyo xa i-working ground wire eqhelekileyo ivuliwe kwaye yahlulwe yi-current kwi-ground wire.

③ Sebenzisa uhlalutyo lwe-chromatographic ukujonga izinga lokuveliswa kwegesi kwindawo apho kukho impazamo khona.

④ Emva kokufumana indawo echanekileyo yempazamo ngokulinganisa, ukuba ayinakujongwa, isiqwenga esiqhelekileyo sokumisa isiseko sesinyithi singasuswa siye kwindawo efanayo yendawo yempazamo ukuze kuncitshiswe kakhulu umbane ojikelezayo.

(2) Amanyathelo okulungisa ngokupheleleyo. Emva kokuba ukubekwa esweni kufumanise ukuba kukho impazamo yokumisa umhlaba enamachaphaza amaninzi kwi-transformer, i-transformer enokuvalwa kufuneka icinywe ngexesha, kwaye impazamo yokumisa umhlaba enamachaphaza amaninzi kufuneka isuswe ngokupheleleyo emva kokuphuma. Ukususa ezo mpazamo, amanyathelo okugcina afanelekileyo kufuneka athathwe ngokohlobo kunye nesizathu sokumisa umhlaba enamachaphaza amaninzi. Nangona kunjalo, kwezinye iimeko, inqaku lempazamo alinakufumaneka emva kokuba umbane ucinyiwe. Ukuze kufunyanwe inqaku lesiseko ngqo, ezi ndlela zilandelayo zingasetyenziswa kwindawo.

① Indlela ye-DC. Vula isiqwenga sokudibanisa sepayipi yesinyithi esingundoqo sentsimbi kunye ne-clamp, uze udlulise i-6V DC kwiishiti zesinyithi ze-silicon kumacala omabini e-joke, uze usebenzise i-DC voltmeter ukulinganisa i-voltage phakathi kwawo onke amanqanaba eeshiti zesinyithi ze-silicon ngokulandelelana. Xa i-voltage ilingana no-zero okanye Xa isalathisi semitha sijikwa, sinokuthathwa njengendawo yokumisa impazamo.

2 Indlela yonxibelelwano. Qhagamshela ukujija kwe-voltage ephantsi ye-transformer kwi-voltage ye-AC ye-220 ~ 380V. Ngeli xesha, kukho i-magnetic flux kwi-hose yesinyithi kunye ne-hose yentsimbi engatyiwayo kwi-iron core. Ukuba kukho iimpazamo ezininzi zomhlaba, sebenzisa i-milliammeter ukulinganisa umbane (i-iron core kunye nee-clamps). Iqhekeza elidibanisayo kufuneka livulwe). Sebenzisa i-milliammeter ukulinganisa inqaku ngenqaku ecaleni kwe-iron jock kuwo onke amanqanaba. Xa umbane kwi-milliampre ingu-zero, yindawo yempazamo.
