Izinga lama-circuit breaker emhlabeni wonke lizofinyelela kumadola ayizigidi eziyizinkulungwane eziyi-8.7 ngonyaka ka-2022, ngesilinganiso sokukhula sonyaka esiyi-4.8%.

Ngokwemininingwane ekhishwe inhlangano yocwaningo lwemakethe yamazwe omhlaba, iMarkets and Markets, imakethe yomhlaba wonke yama-circuit breaker izofinyelela kumadola ayizigidi eziyizinkulungwane eziyi-8.7 ngonyaka ka-2022, ngenani lokukhula elihlanganisiwe lonyaka elingu-4.8% phakathi naleso sikhathi.
Ukwenyuka kwemisebenzi kagesi kanye nentuthuko yokwakha emazweni asathuthuka, kanye nokwenyuka kwenani lamaphrojekthi okukhiqiza amandla kagesi avuselelekayo, kungamandla amakhulu okukhula kwemakethe yama-circuit breaker.

Ngokwabasebenzisi bokugcina, imakethe yamandla avuselelekayo kulindeleke ukuthi ikhule ngesilinganiso sokukhula sonyaka esisezingeni eliphakeme 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 ye-circuit breaker.Ama-Circuit breaker asetshenziselwa ukubona amaphutha futhi avikele izinto zikagesi kugridi.
Ngokohlobo lohlelo lokusebenza, imakethe ye-breaker circuit yangaphandle inesabelo semakethe esikhulu kunazo zonke ngesikhathi sokubikezela futhi izobusa imakethe ngesikhathi sokubikezela ngoba ingahlinzeka ngokusebenza kahle kwesikhala, izindleko zokulungisa eziphansi kanye nokuvikelwa ezimweni ezeqisayo zemvelo.

Ngokwesilinganiso sesifunda, isifunda sase-Asia-Pacific sizothatha usayizi wemakethe omkhulu kunayo yonke ngesikhathi sokubikezela futhi sizokhula ngesilinganiso esiphakeme kakhulu sokukhula konyaka ngesikhathi sokubikezela.
Ngokwezici zokushayela, ngokukhula okuqhubekayo kwesibalo sabantu, imisebenzi eqhubekayo yokwakha nokuthuthukiswa komnotho (imisebenzi yezimboni neyezohwebo) emhlabeni wonke ibangele ukuthi izinkampani zezinsiza zomphakathi zihlele ukuthuthukisa nokusungula ingqalasizinda entsha kagesi.Ngokukhula kwesibalo sabantu, isidingo semisebenzi yokwakha nokuthuthukiswa kwezomnotho osafufusa esifundeni sase-Asia-Pacific, eMpumalanga Ephakathi nase-Afrika sinyukile.
I-China iyimakethe yezokwakha enkulu kunazo zonke emhlabeni, futhi uhlelo lukahulumeni waseShayina oluthi “One Belt One Road” luhlinzeka ngamathuba emisebenzi yaseChina yokwakha neyokuthuthukiswa.Ngokohlelo lwaseChina lweminyaka eyi-13 (2016-2020), iChina ihlela ukutshala imali eyizigidigidi ezingama-538 zamaRandi ekwakhiweni kukaloliwe.I-Asian Development Bank ilinganisela ukuthi phakathi kuka-2010 no-2020, kuzodingeka ukuthi kutshalwe ama-US$8.2 trillion kumaphrojekthi kazwelonke wokutshalwa kwengqalasizinda e-Asia, okulingana cishe no-5% we-GDP yesifunda.Ngenxa yemisebenzi emikhulu ezayo ehleliwe eMpumalanga Ephakathi, njenge-2020 Dubai World Expo, i-UAE kanye ne-Qatar FIFA 2022 World Cup, izindawo zokudlela ezintsha, amahhotela, izinxanxathela zezitolo nezinye izakhiwo zizonke zisakhiwa ukuze kuthuthukiswe ukuthuthukiswa kwengqalasizinda yasemadolobheni. esifundeni.Ukukhula kwemisebenzi yokwakha nokuthuthukiswa kwezomnotho esafufusa esifundeni sase-Asia-Pacific kanye naseMpumalanga Ephakathi nase-Afrika kuzodinga ukutshalwa kwezimali okwengeziwe ekuthuthukisweni kwengqalasizinda yokudlulisela nokusabalalisa, okuholela ekudingeni okwengeziwe kwabaphuli bezifunda.

Kodwa-ke, umbiko uphinde waveza ukuthi imithetho eqinile yezemvelo nezokuphepha yama-SF6 ama-circuit breaker ingaba nomthelela othile emakethe.Amajoyinti angaphelele ekwakhiweni kwama-circuit breaker e-SF6 azodala ukuvuza kwegesi ye-SF6, okuwuhlobo lwegesi encisha umoya ngokwezinga elithile.Lapho ithangi eliphukile livuza, igesi ye-SF6 inzima kunomoya, ngakho izozinza endaweni ezungezile.Lokhu kufakwa kwegesi kungase kubangele ukuminyanisa komsebenzisi.I-US Environmental Protection Agency (EPA) ithathe izinyathelo zokuthola isisombululo esingakwazi ukubona ukuvuza kwegesi ye-SF6 ebhokisini le-circuit breaker ye-SF6, ngoba uma i-arc kwakhiwa, ukuvuza kungabangela umonakalo.
Ukwengeza, ukuqapha kude kwemishini kuzokwandisa ubungozi bobugebengu be-inthanethi embonini.Ukufakwa kwama-circuit breaker esimanje kubhekene nezinselelo eziningi, okubeka engcupheni umnotho wezwe.Amadivayisi ahlakaniphile asiza isistimu ukuthi ifinyelele imisebenzi engcono, kodwa amadivayisi ahlakaniphile angase alethe izinsongo zokuphepha ezivela ezintweni eziphikisana nomphakathi.Izinyathelo zokuphepha ekufinyeleleni ukude zingeqiwa ukuze kuvinjelwe ukwebiwa kwedatha noma ukwephulwa kwezokuphepha, okungase kubangele ukucisha kukagesi kanye nokucisha.Lokhu kuphazamiseka kuwumphumela wezilungiselelo ku-relay noma i-circuit breaker, enquma impendulo (noma ayikho impendulo) yocingo.
Ngokusho kweGlobal Information Security Survey ka-2015, ukuhlaselwa kwe-inthanethi ezimbonini zamandla nezinsiza kukhuphuke kusuka ku-1,179 ngo-2013 kuya ku-7,391 ngo-2014. Ngo-December 2015, ukuhlasela kwe-inthanethi kwegridi yamandla yase-Ukraine kwaba ukuhlasela kwe-inthanethi okuyimpumelelo.Abagebengu bavale ngempumelelo iziteshi ezingaphansi ezingu-30 e-Ukraine futhi bashiya abantu abangu-230,000 bengenawo ugesi phakathi nehora elilodwa kuya kwangu-6.Lokhu kuhlasela kubangelwe isofthiwe enonya eyethulwa kunethiwekhi yokusetshenziswa ngobugebengu bokweba imininingwane ebucayi ezinyangeni ezimbalwa ezedlule.Ngakho-ke, ukuhlaselwa kwe-cyber kungabangela umonakalo omkhulu kwingqalasizinda yamandla yezinsiza zomphakathi.
