Izindaba

I-transformer ngayinye inepuleti lensimbi elisebenza njengekhadi layo lokuzazisa—ipuleti legama. Kwabochwepheshe bokuthenga, onjiniyela, kanye nabaphathi bezimpahla, ukuqonda lolu lwazi kubalulekile. Ipuleti legama liqukethe izibalo ezibalulekile ezichaza ukuthi i-transformer ingasebenza kanjani, ixhunywe futhi igcinwe kanjani kuyo yonke impilo yayo yenkonzo.

Iningi lempilo yabo yokusebenza, ama-transformer asebenza buthule. Izinkinga ziyavela ngaphakathi—ukushisa kuyawohloka, ukuxhumana kuyakhululeka, kwakheka izindawo ezishisayo—ngaphandle kwesixwayiso esibonakalayo. Ngesikhathi ukuvikelwa okuvamile kusebenza, umonakalo uvame ukuba usuvele wenziwe.

Kumshini omkhulu oguqula amandla, uhambo oluvela efektri ukuya esiteshini esincane luyinselele yobunjiniyela ngokwalo. Njengoba inesisindo esingamakhulu amathani futhi iqukethe izingxenye zangaphakathi ezibucayi, lezi zimpahla zibhekene nezingozi ezinkulu ngesikhathi sokuthutha—izingozi ezingaholela emonakalweni ofihliwe kanye nokwehluleka kwangaphambi kwesikhathi. Ukuqonda ukuhamba kwemishini yokuthutha kanye nokufakwa kwe-transformer kubalulekile kochwepheshe bokuthenga okumele baqinisekise ukuthi ukutshalwa kwezimali kwabo kufika ngokuphephile futhi kusebenza ngokwethembeka.

Uwoyela we-transformer uvame ukubizwa ngokuthi "igazi" le-transformer. Uyavikela, upholise, uvikele, futhi uxilonge ngisho nokuxilonga. Sekuyiminyaka engaphezu kwekhulu, uwoyela wamaminerali otholakala ku-petroleum ubelokhu uyindlela ejwayelekile yokukhetha. Kodwa ukukhathazeka okwandayo kwemvelo kanye nezidingo zokuphepha emlilweni kuye kwaholela ekuthuthukisweni kwezinye izindlela—okuphawuleka kakhulu, uwoyela we-ester wemvelo otholakala emithonjeni yemifino.

Uma uthenga i-transformer, imininingwane yobuchwepheshe ilandisa ingxenye nje yendaba. Ubufakazi bangempela bekhwalithi busezibikweni zokuhlolwa kanye namamaki okuqinisekisa. Kwabachwepheshe bokuthenga abazulazula ezimakethe zomhlaba wonke, ukuqonda ukuthi lezi zivivinyo zisho ukuthini nokuthi yiziphi izitifiketi ezibalulekile kungasho umehluko phakathi kokutshalwa kwezimali okuthembekile kanye nephutha elibizayo.

Isikhathi sokuphila kwe-transformer sinqunywa kakhulu yizinga lokushisa lokusebenza kwayo. Kuwo wonke amazinga okushisa angu-6 kuya kwangu-8 Celsius akhuphuka ngaphezu kwezinga lokushisa elilinganiselwe, impilo yokuvikela incishiswa phakathi. Lobu budlelwano obuyisisekelo benza izinhlelo zokupholisa zingagcini nje ngokuba yizingxenye ezisizayo, kodwa futhi zibe yizinto ezibalulekile ezinquma ubude besikhathi sempahla kanye nokuthembeka kwayo.

Njengoba amapulazi omoya asogwini lolwandle ehamba ibanga elide esuka ogwini—ngalé kwamakhilomitha ayi-100 emanzini ajulile—ukudluliselwa kwe-AC kwendabuko kufinyelela imikhawulo yayo yobuchwepheshe. Izintambo zangaphansi kolwandle zisebenza njenge-capacitor ezinkulu, zidla amandla asabelayo futhi zenze ukulethwa kwamandla okuphumelelayo kungenzeki emabangeni amade. Yilapho ubuchwepheshe bokudlulisa obuguquguqukayo be-high-voltage direct current (HVDC) buba yinto ebalulekile, futhi kanye nayo, isigaba esisha sama-transformer akhethekile.

Kwenzekani ku-transformer uma ingasakwazi ukulungiswa noma ukwenziwa kabusha? Sekungamashumi eminyaka, impendulo yayilula: indawo yokulahla udoti noma ukubuyiselwa kwezinsalela eziyisisekelo. Namuhla, leyo ndlela iyashintsha. Ngemithethonqubo yezemvelo ekhulayo, izindleko zezinto zokusetshenziswa ezikhulayo, kanye nezibopho zokusimama kwezinkampani, ukudilizwa nokusetshenziswa kabusha kwama-transformer angasasebenzi kuye kwavela enkambisweni yezimboni eyinkimbinkimbi.

Kubakhiqizi nabathengi bama-transformer, izindleko zezinto zokusetshenziswa aziyona inkinga yangemuva—kuyinto ebalulekile emananini, inzuzo, kanye nokusebenza kahle kwephrojekthi. Ama-transformer ayimikhiqizo edinga izinto eziningi, kanti insimbi kagesi egxile ethusi kanye nokusanhlamvu (GOES) kuphela ibangela ingxenye enkulu yezindleko zokukhiqiza. Lapho la manani ezimpahla eshintsha, imiphumela isakazeka kulo lonke uchungechunge lokuhlinzeka.

Kwenzekani kumshini oguqulayo ekupheleni kwesikhathi sawo sokusebenza? Sekungamashumi eminyaka impendulo ilula: yilahle noma uyithumele endaweni yokulahla udoti. Namuhla, indlela ehlukile iyanda—enikeza izinzuzo ezikhangayo kokubili kubanikazi bezimpahla kanye nemvelo.
