IMakethe yeGlobal DC yeSekethe yoPhulo lweSekethe ikhula ngokukhawuleza, kwaye iScale siyaKudlula i-27 yebhiliyoni yeYuan ngo-2026.

   DC zesekethe breakersinokusetyenziswa ngokubanzi kumandla ombane, ukunikezelwa kwamandla, izithuthi zombane, ukuhamba ngololiwe, iinqanawa, amaziko edatha kunye nezinye iindawo.

I-DC circuit breaker yi-circuit breaker esetyenziselwa ukwaphula isekethe ye-DC, kwaye iqonda i-DC yokuqhawula xa i-current inqumla i-point ye-zero.I-DC breaker yesiphaluka inomda ohlukileyo wangoku kunye nenkqubo yokucima i-arc, enegunya elinamandla langoku lokukhawulelana, ukuchaneka okuphezulu kokukhusela i-relay, ukhuseleko oluzenzekelayo ekugqithiseni kunye nezinye iipropati, ezinokumisela ngokukhawuleza impazamo yenkqubo yokusabalalisa i-DC yokuvula nokuvala ukusebenza.I-DC circuit breaker yenye yezixhobo eziphambili ze-DC transmission lines.Ngokwandiswa okuqhubekayo kwesikali sokwakhiwa kothungelwano lwamandla e-DC, ngakumbi uphuhliso olukhawulezayo lwenethiwekhi yamandla ye-UHV DC, ebekwe phezulu kwimfuno yezinye iindawo zesicelo, isikali semalike yesekethe ye-DC siyakhula.

Ngokwezixhobo ezohlukeneyo ezingundoqo zokwaphula iisekethe ze-DC, izaphuli zesekethe ze-DC zinokwahlulwa zibe ziindidi ezintathu: oomatshini abaqhekeza isekethe ye-DC, i-slid-state DC izaphuli zesekethe, kunye ne-hybrid DC yezaphuli zesekethe.Phakathi kwazo, ezona zixhaphakileyo zisetyenziswa ngoomatshini ii-DC zesekethe ikakhulu zibandakanya ii-vacuum circuit breakers, sulfur hexafluoride circuit breakers, njl., ezinolona luhlu lubanzi lwesicelo;inxalenye engundoqo ye-slid-state DC abaphuli beesekethe yi-thyristor, kunye nophando kwintsimi yesicelo e-China igxile kakhulu kwiinqanawa, i-Aerospace kunye nezinye iindawo;I-Hybrid DC isaphuli sesekethe yimveliso yokudibanisa oomatshini kunye ne-slid-state DC isaphuli sesekethe, enezibonelelo zombini kwaye ibe yindawo eshushu yophando kunye nesicelo.

Izaphuli zesekethe zeDC zinokusetyenziswa ngokubanzi kumandla ombane, unikezelo lwamandla, izithuthi zombane, ukuhamba ngololiwe, iinqanawa, amaziko edatha kunye namanye amacandelo.Kwintsimi yamandla ombane, ngohlengahlengiso lwesakhiwo samandla, imfuno yoqhagamshelo lwegridi yokuvelisa amandla ombane amatsha iyaqhubeka nokukhula.Ukusukela ukuba iintambo zothumelo lweDC zinokuqonda unikezelo lwamandla amaninzi kunye nonikezelo lwamandla amaninzi, zinokusombulula iingxaki ezahlukeneyo ezibangelwa ludibaniso lwegridi yamandla amatsha.Isikali siyaqhubeka nokwandisa, siqhuba imfuno ekhulayo yee-DC ze-circuit breakers.Ukongeza, ukunyuka okukhawulezayo kwenani lokwenziwa kwedatha kunye nokunyuka okuqhubekayo kwenani lokwakhiwa kweziko ledatha kuye kwaba yenye into ebalulekileyo yokuqhubela phambili kwemfuno ye-DC breakers.

Ngokwe-“2022-2026 DC Circuit Breaker Industry In-Depten Market Research and Investment Strategy Suggestion Report” ekhutshwe liZiko loPhando loShishino iXinsijie, ngo-2021, ubungakanani bemakethi ye-DC ye-circuit breaker buza kuba malunga ne-16.3 yeebhiliyoni zeeyuan.Ukuxhamla kuphuhliso lwamandla asezantsi, iziko ledatha, ezothutho kunye namanye amashishini, kulindeleke ukuba ukusuka ngo-2022 ukuya ku-2026, imakethi ye-DC ye-circuit breaker market iya kukhula ngokukhawuleza kwizinga lokukhula lonyaka elimalunga ne-10.6%, kwaye ubungakanani bemarike buya kukhula ngokukhawuleza. ukufikelela ngaphezu kwe-27 yeebhiliyoni zeeyuan ngo-2026.Ishishini lehlabathi jikelele le-DC le-circuit breaker liphuhla ngamandla.

Ngokutsho kwabahlalutyi bemizi-mveliso abavela eXinsijie, kwihlabathi, abavelisi beesekethe ze-DC ikakhulu baquka i-ABB yaseSwitzerland, iSchneider yaseFransi, iLegrand yaseFransi, iSiemens eJamani, iEaton eUnited States, iSensata Technologies eUnited States, iMitsubishi yaseJapan, kunye neFuji Electric eJapan.E-China, abavelisi abaphambili bezaphuli zesekethe ze-DC ikakhulu babandakanya i-Guodian NARI, i-Xuji Electric, i-Slocable, njl.njl. Phakathi kwabo, i-ABB yaseSwitzerland kunye ne-Schneider yaseFransi ngabona bavelisi abakhulu behlabathi be-DC breakers, kunye nesabelo semarike esidityanisiweyo esimalunga nama-25. %.
