Ngokukhula okuqhubekayo kwesibalo sabantu, ukwakhiwa okuqhubekayo kanye nemisebenzi yokuthuthukisa umnotho (kokubili eyezimboni neyezohwebo) emhlabeni wonke yenza izinkampani zezinsiza zomphakathi zihlele ukuthuthukisa kanye nokwakha ingqalasizinda yamandla amasha. Ngokukhula kwesibalo sabantu, umsebenzi okhulayo wokwakha nokuthuthukiswa kwezomnotho osafufusa wase-Asia Pacific kanye naseMpumalanga Ephakathi nase-Afrika uzodinga ukutshalwa kwezimali okwengeziwe ekuthuthukisweni kwengqalasizinda yokudlulisa nokusabalalisa, okuholela esidingweni esithe xaxa sabaphuli bezifunda.
Ukwenyuka kwemisebenzi kagesi kanye nentuthuko yokwakha emazweni asathuthuka, kanye nokwenyuka kwenani lamaphrojekthi okukhiqiza amandla avuselelekayo, yizona ezihamba phambili zokukhula kwemakethe ye-circuit breaker. Imakethe yamandla avuselelekayo kulindeleke ukuthi ikhule ku-CAGR ephezulu kakhulu ngesikhathi sokubikezela. Ukwenyuka kokutshalwa kwezimali kumandla avuselelekayo ukuze kunqandwe ukuphuma kwe-CO2 kanye nesidingo esikhulayo sokuphakelwa kukagesi yizona zinto ezihamba phambili eziqhuba ukukhula komkhakha wamandla avuselelekayo emakethe yama-circuit breaker. Izinqamuli zesekethe zisetshenziselwa ukubona amaza amaphutha futhi zivikele izinto zikagesi kugridi yamandla.
I-circuit breaker ngokobubanzi bayo obujwayelekile be-voltage ingahlukaniswa i-high voltage circuit breaker kanye ne-low voltage circuit breaker. I-low-voltage circuit breaker iyingxenye eyinhloko emele enesakhiwo esiyinkimbinkimbi, okuqukethwe okuphezulu kwezobuchwepheshe kanye nenani eliphezulu lezomnotho emshinini kagesi we-low-voltage. Idlala indima ebalulekile ohlelweni lokusabalalisa i-low-voltage. Ama-circuit breaker ane-voltage ephezulu, imishini eyinhloko yokulawula amandla ezitshalweni zikagesi neziteshi ezingaphansi, anesabelo semakethe esikhulu kunazo zonke emakethe yama-circuit breaker angaphandle ngesikhathi sokubikezela futhi azobusa imakethe ngesikhathi sokubikezela ngoba ahlinzeka ngokusebenza kwendawo, izindleko zokulungisa eziphansi. kanye nokuvikelwa ezimweni ezimbi kakhulu zemvelo.
I-China iyimakethe yezokwakha enkulu kunazo zonke emhlabeni, futhi i-Belt and Road Initiative kahulumeni wase-China inikeze amathuba omsebenzi wokwakha nokuthuthukisa e-China. Ngokohlelo lwaseChina lweminyaka eyi-13 lweminyaka emihlanu (2016-2020), iChina ihlela ukutshala imali eyizigidigidi ezingama-538 ekwakhiweni kukaloliwe. I-Asian Development Bank ilinganisela ukuthi kunesidingo sokutshala u-$8.2tn kumaphrojekthi kazwelonke wokutshalwa kwengqalasizinda e-Asia phakathi kuka-2010 no-2020, okulingana cishe namaphesenti angu-5 e-GDP yesifunda. Ngenxa yemicimbi emikhulu ezayo ehleliwe eMpumalanga Ephakathi, njenge-Dubai Expo 2020 kanye ne-FIFA World Cup 2022 e-UAE naseQatar, izindawo zokudlela ezintsha, amahhotela, izinxanxathela zezitolo nezinye izakhiwo ezibalulekile ziyakhiwa ukuze kuthuthukiswe ukuthuthukiswa kwengqalasizinda yasemadolobheni. isifunda. Umsebenzi okhulayo wokwakha nokuthuthukisa emazweni asathuthuka e-Asia-Pacific kanye naseMpumalanga Ephakathi nase-Afrika uzodinga ukutshalwa kwezimali okwengeziwe ekuthuthukisweni kwengqalasizinda ye-T&D, okuholela esidingweni esengeziwe sabaphuli bezifunda.
Kodwa-ke, lo mbiko uphinde waphawula ukuthi imithetho eqinile yezemvelo nezokuphepha yama-SF6 ama-circuit breaker ingaba nomthelela emakethe. Amalunga angaphelele ekwenziweni kwe-SF6 circuit breaker angabangela ukuvuza kwegesi ye-SF6, okuwuhlobo lwegesi ephefumulayo ngokwezinga elithile. Lapho ithangi eliphukile livuza, igesi ye-SF6 inzima kunomoya ngakho-ke izozinza endaweni ezungezile. Le mvula yegesi ingabangela u-opharetha ukuthi aphelelwe umoya. I-US Environmental Protection Agency (EPA) ithathe izinyathelo zokuthola isisombululo sokuthola ukuvuza kwegesi ye-SF6 emabhokisini e-SF6, okungadala umonakalo lapho kwakhiwa i-arc.
Ukwengeza, ukuqapha okukude kwemishini kuzokwandisa ubungozi bobugebengu be-inthanethi embonini. Ukufakwa kwama-circuit breaker esimanje kubhekene nezinselelo eziningi futhi kubangela usongo emnothweni wezwe. Amadivayisi ahlakaniphile asiza isistimu ukuthi isebenze kahle, kodwa amadivayisi ahlakaniphile angase abe usongo lokuvikeleka ezintweni eziphikisana nomphakathi. Ukwebiwa kwedatha noma ukwephulwa kwezokuphepha kungavinjelwa ngokudlula izinyathelo zokuphepha ekufinyeleleni ukude, okungaholela ekunqamukeni kukagesi kanye nokucima. Lokhu kuphazamiseka kuwumphumela Wezilungiselelo kuma-relay noma ama-circuit breaker anquma impendulo (noma ukungaphenduli) kwezinto zokusebenza.
