Ngokukhula okuqhubekayo kwabemi, ulwakhiwo oluqhubekayo kunye nemisebenzi yophuhliso loqoqosho (zombini zoshishino kunye nezorhwebo) kwihlabathi jikelele zenza iinkampani eziluncedo zikawonkewonke zicwangcise ukuphucula kunye nokwakha iziseko zombane ezitsha. Ngokunyuka kwamanani abantu, ukukhula komsebenzi wokwakha kunye nophuhliso kuqoqosho olusakhulayo lweAsia Pacific kunye noMbindi Mpuma kunye neAfrika kuya kufuna utyalo-mali olungaphezulu kuphuhliso lweziseko ezingundoqo zokusasaza nokusasaza, okukhokelela kwimfuno engakumbi yabaphuli beesekethe.
Ukonyuka kobonelelo lwamandla kunye nemisebenzi yophuhliso lokwakha kumazwe asakhasayo, kunye nokwanda kwenani leeprojekthi zokuvelisa amandla ahlaziyekayo, zezona zinto ziqhuba ukukhula kwemarike ye-circuit breaker. Imakethi yamandla avuselelekayo kulindeleke ukuba ikhule kwi-CAGR ephezulu ngexesha loqikelelo. Ukonyuka kotyalo-mali kumandla ahlaziyekayo ukunqanda ukukhutshwa kwe-CO2 kunye nemfuno ekhulayo yobonelelo lombane zezona zinto ziqhuba ukukhula kwecandelo lamandla ahlaziyekayo kwimakethi ye-circuit breaker. I-Circuit breakers isetyenziselwa ukufumanisa i-current currents kunye nokukhusela izixhobo zombane kwigridi yamandla.
I-breaker circuit ngokoluhlu lwalo lombane oluqhelekileyo lunokwahlulwa lube yi-high voltage circuit breaker kunye ne-low voltage circuit breaker. I-low-voltage circuit breaker iyona nxalenye yommeli oyintloko kunye nesakhiwo esiyinkimbinkimbi, umxholo ophezulu wezobugcisa kunye nexabiso eliphezulu lezoqoqosho kwi-low-voltage yezixhobo zombane. Idlala indima ebalulekileyo kwinkqubo yokusabalalisa i-voltage ephantsi. Izaphuli zesekethe ezinevoltage ephezulu, ezona zixhobo ziphambili zolawulo lwamandla ombane kunye nezikhululo ezincinci, zinesabelo esikhulu semakethi kwimakethi yezaphuli zesekethe yangaphandle ngexesha loqikelelo kwaye ziya kulawula intengiso ngexesha loqikelelo kuba zibonelela ngokulungiswa kwendawo, iindleko zokugcinwa okuphantsi. kunye nokukhuselwa kwiimeko ezinzima zendalo.
I-China yeyona marike yolwakhiwo inkulu ehlabathini, kwaye iNyathelo likarhulumente waseTshayina iBelt and Road Initiative libonelele ngamathuba omsebenzi wokwakha nophuhliso eTshayina. Ngokutsho kwe-China ye-13 yeSicwangciso seminyaka emihlanu (2016-2020), i-China iceba ukutyala i-538 yezigidigidi zeedola kulwakhiwo lukaloliwe. IBhanki yoPhuhliso yaseAsia iqikelela ukuba kukho imfuneko yokutyala i-8.2tn yeedola kwiiprojekthi zotyalo-mali lweziseko zophuhliso zesizwe e-Asia phakathi kwe-2010 kunye ne-2020, elingana ne-5 pesenti ye-GDP yommandla. Ngenxa yemisitho emikhulu ezayo ecwangcisiweyo kuMbindi Mpuma, efana neDubai Expo 2020 kunye neNdebe yeHlabathi yeFIFA ka-2022 e-UAE naseQatar, iindawo zokutyela ezintsha, iihotele, iivenkile ezinkulu kunye nezinye izakhiwo ezidityanisiweyo ziyakhiwa ukukhuthaza uphuhliso lweziseko zophuhliso ezidolophini. ummandla. Umsebenzi okhulayo wokwakha kunye nophuhliso kuqoqosho olusakhulayo lwase-Asia-Pacific kunye noMbindi Mpuma kunye ne-Afrika kuya kufuna utyalo-mali olungakumbi kuphuhliso lweziseko ezingundoqo ze-T&D, okukhokelela kwimfuno engakumbi yabaphuli beesekethe.
Nangona kunjalo, ingxelo iphinde yaqaphela ukuba imimiselo engqongqo yokusingqongileyo kunye nokhuseleko lwe-SF6 izaphuli zesekethe inokuba nefuthe kwimarike. Amalungu angafezekanga kwi-SF6 yokuvelisa i-circuit breaker angabangela ukuvuza kwegesi ye-SF6, eluhlobo lwegesi yokuphefumla ukuya kumlinganiselo othile. Xa itanki eyaphukileyo ivuza, igesi ye-SF6 inzima kunomoya kwaye ngoko iya kuhlala kwindawo eyingqongileyo. Oku kuna kwerhasi kunokubangela ukuba umsebenzi afuthaniseleke. I-Arhente ye-Environmental Protection Agency (EPA) ithathe amanyathelo okufumana isisombululo sokubona ukuvuza kwegesi ye-SF6 kwiibhokisi ze-SF6 ze-breaker, ezinokubangela umonakalo xa i-arc yenziwe.
Ukongeza, ukubekwa esweni okude kwezixhobo kuya kwandisa umngcipheko wolwaphulo-mthetho lwe-cyber kushishino. Ukufakwa kwee-circuit breakers zanamhlanje kujongene nemingeni emininzi kwaye kubangela ingozi kuqoqosho lwelizwe. Izixhobo ezihlakaniphile zinceda inkqubo ukuba isebenze ngokufanelekileyo, kodwa izixhobo ezihlakaniphile zinokubeka isoyikiso sokhuseleko kwizinto ezichasene noluntu. Ubusela bedatha okanye ukuphulwa kokhuseleko kunokuthintelwa ngokudlula imilinganiselo yokhuseleko ekufikeleleni kude, okunokubangela ukucima kombane kunye nokuhamba. Ezi ziphazamisi zisisiphumo se-Settings kwi-relays okanye ii-circuit breakers ezimisela impendulo (okanye ukungaphenduli) kwezixhobo.
