Ukuhlangabezana neMigangatho yoKhuseleko kunye neeMfuno zeTransformer

Ukuhlangabezana neMigangatho yoKhuseleko kunye neeMfuno zeTransformer

Ukubaluleka kokuhlangabezana nemigangatho yokhuseleko kunye neemfuno ze-transformer ayikwazi ukugqithiswa. Iinguqu zidlala indima ebalulekileyo ekusasazeni umbane, kwaye ziqinisekisa ukuba ziyilwe, zifakelwe, kwaye zigcinwe ngokuhambelana nemigangatho yokhuseleko kubalulekile ekukhuseleni abantu kunye nepropati. Kule nqaku, siza kuphonononga imigangatho eyahlukeneyo yokhuseleko esebenza kubaguquli, kunye neemfuno ekufuneka zifezekiswe ukuqinisekisa ukuthotyelwa.

Ukuqonda iMigangatho yoKhuseleko yeeTshintsho

Imigangatho yokhuseleko yeenguqu zisekwe ukuqinisekisa ukuba la macandelo abalulekileyo asebenza ngokukhuselekileyo nangokuthembekileyo. Kukho imibutho emininzi ephuhlisa kwaye igcine imigangatho yokhuseleko kubaguquli, kubandakanywa uMbutho weSizwe waBavelisi boMbane (i-NEMA), iZiko leeNjineli zoMbane kunye ne-Electronics (IEEE), kunye neKhomishoni ye-Electrotechnical International (IEC). Le migangatho ibandakanya uluhlu olubanzi lwezihloko, kubandakanywa ubuncinane bokukhutshwa, imilinganiselo yokunyuka kwamaqondo obushushu, kunye namanqanaba okugquma. Ukuthobela le migangatho kubalulekile ekuqinisekiseni ukusebenza ngokukhuselekileyo kweenguqu kunye nokukhusela abasebenzi kwiingozi ezifana nokutshitshiswa kombane kunye neziganeko ze-arc flash.

EUnited States, iKhowudi yeSizwe yoMbane (NEC) ibeka ezininzi iimfuno zokhuseleko ezisebenza kubaguquli. Ezi mfuno zijongene nemiba efana nokufakelwa, i-wiring, kunye nokubekwa phantsi kwee-transformers, kunye nokukhuselwa kwee-transformers kwiimeko ezigqithisiweyo kunye nokugqithisa. Ukuthotyelwa kwe-NEC kunyanzelekile kwiindawo ezininzi zolawulo, kwaye ukungaphumeleli ukuthobela iimfuno zayo kunokubangela iziphumo ezibi, kubandakanywa iintlawulo, izohlwayo kunye noxanduva lomthetho.

Ukuyila iiTransformers zoKhuseleko

Enye yezona zinto zibalulekileyo zokuhlangabezana nemigangatho yokhuseleko kunye neemfuno ze-transformer kuyilo lweziguquli ngokwazo. Iziguquli kufuneka ziyilwe ngokhuseleko engqondweni, kuquka iimpawu ezinciphisa umngcipheko wokothuka kombane, umlilo, kunye nezinye iingozi. Oku kubandakanya ukusetyenziswa kwezixhobo ezifanelekileyo, ukufakwa kweendlela zokhuseleko ezifana nokhuseleko oludlulayo, kunye nokufakwa kweelebhile ezilumkisayo kunye neempawu zokulumkisa abasebenzi ngeengozi ezinokubakho.

Ukongeza kwezi ngqwalasela zokhuseleko ngokubanzi, ii-transformers kufuneka ziyilwe ukuhlangabezana neemfuno ezithile zesicelo. Ngokomzekelo, i-transformers esetyenziswe kwiindawo ezinobungozi, ezifana nezixhobo ze-oyile kunye negesi okanye izityalo zokulungiswa kweekhemikhali, kufuneka zenzelwe ukuhlangabezana neemfuno ze-National Fire Protection Association (NFPA) kunye neminye imigangatho efanelekileyo. Oku kunokubandakanya iimpawu ezifana neendawo ezivaliweyo ezingagqabhukiyo, izixhobo zokugquma ezikhethekileyo, kunye nezinye izinto eziqwalaselweyo zokunciphisa imingcipheko eyayanyaniswa nale meko.

Ukufakela kunye nokugcina iiTransformers ngokuKhuselekileyo

Ufakelo olufanelekileyo kunye nokugcinwa kubalulekile ekuqinisekiseni ukuba ii-transformers zisebenza ngokukhuselekileyo nangokuthembeka. Ngexesha lofakelo, i-transformers kufuneka ifakwe ngokuhambelana neziphakamiso zomenzi kunye nemigangatho yokhuseleko olusebenzayo. Oku kubandakanya ukuqwalaselwa okunjengokumisa ngokufanelekileyo, ukucocwa, kunye nokungenisa umoya ukuqinisekisa ukuba i-transformer isebenza ngaphakathi kweeparamitha zayo zokuyila.

Nje ukuba zifakwe, ii-transformers kufuneka zigcinwe rhoqo ukuqinisekisa ukusebenza kwazo ngokukhuselekileyo. Oku kubandakanya imisebenzi efana nokubeka iliso kumanqanaba e-oyile, uvavanyo lokumelana nokugquma, kunye nokuqinisekisa ukuba izixhobo ezikhuselayo ezifana ne-fuses kunye ne-breaker circuit zisebenza kakuhle. Ukugcinwa rhoqo akuncedi kuphela ukuthintela ukungaphumeleli okungalindelekanga kunye nexesha lokuphumla kodwa kuqinisekisa ukuba abaguquli bayaqhubeka nokusebenza ngokukhuselekileyo kunye nokuthobela imigangatho yokhuseleko esebenzayo.

Ukukhuselwa kwiziganeko zeArc Flash

Iziganeko ze-Arc flash ziyingozi enkulu ehambelana neziguquli, kwaye ukukhusela kuzo ngumba obalulekileyo wokuhlangabezana nemigangatho yokhuseleko. Ukukhanya kwe-arc kunokukhupha amandla amakhulu, okubangela ukutshisa okugqithisileyo, ukwenzakala, kunye nokufa kubasebenzi abakuloo ngingqi. Ukukhusela kwiziganeko ze-arc flash, ii-transformers kufuneka ziyilwe, zifakwe, kwaye zigcinwe ngokuhambelana neemfuno zemigangatho efana ne-NFPA 70E, ejongene nokhuseleko lombane kwindawo yokusebenza.

Ukukhusela kwiziganeko ze-arc flash kubandakanya iingqwalasela ezininzi, kubandakanywa ukusetyenziswa kwezixhobo ezifanelekileyo zokukhusela (i-PPE), ukuleyibheli kunye nemiqondiso ukulumkisa abasebenzi ngeengozi ezinokuthi zibe khona, kunye noqeqesho olufanelekileyo kunye nemfundo yabasebenzi abanokuthi bavezwe kwiingozi ze-arc flash. Ukongeza, uyilo kunye nofakelo lweziguquli kufuneka lubandakanye iimpawu ezinjengee-arc-resistant enclosures kunye namanye amanyathelo okukhusela ukunciphisa imingcipheko ehambelana neziganeko ze-arc flash.

Ukuqukumbela

Ukuhlangabezana nemigangatho yokhuseleko kunye neemfuno ze-transformer kubalulekile ekuqinisekiseni ukusebenza okukhuselekileyo nokuthembekileyo kwala macandelo abalulekileyo. Ukuthotyelwa kwemigangatho yokhuseleko kunceda ukukhusela abasebenzi kwiingozi ezifana nokutshitshiswa kombane kunye neziganeko ze-arc flash, kunye nokuthintela umonakalo kwipropati kunye nezixhobo. Ngokuqonda imigangatho yokhuseleko esebenza kwi-transformers, ukuyila i-transformers yokhuseleko, ukufaka kunye nokugcina i-transformers ngokukhuselekileyo, kunye nokukhusela iziganeko ze-arc flash, imibutho inokuqinisekisa ukuba abaguquli babo basebenza ngokuhambelana nemigangatho yokhuseleko esebenzayo kwaye baqhubeke nokubonelela ngenkonzo ethembekileyo kwinjongo yabo. izicelo. Ukuthotyelwa kwemigangatho yokhuseleko ngumba obalulekileyo woyilo, ukufakwa, nokugcinwa kwe-transformer, kunye nokuqinisekisa ukuba iziguquli ziyahlangabezana nezi mfuno zibalulekile ekukhuseleni abasebenzi kunye nepropathi.
