Fadada na ABB Solid-State DC Circuit Breaker!

Matakin da duka mai karfi suna zama mafi yawan gaskiya, tare da cikin hankali masu kwallon kashi na DC suka zama zan iya amfani da su wajen kawo karshen kashi a wurin da ya fi kyau da shirye-shiryen da ya fi kyau da kudin da ya fi tsawo.

Matakin da suke da grid na DC a wurin su sun tabbatar da suke iya yi aiki a kan nazarin energy ta fi kyau, tun bayar da kisan cutar. Wannan ya haɗa da kayayyakin karshi da kudin da ya fi kyau waɗanda ke amfani da matakin da suke da abincin zuwa mataki na fari. Figura 1 ta bayyana misalai na cikin kwallon kashi na DC.

Matsayin kwallon kashi na DC ita ce muhimmanci a matsayin koyar da damar samun rike da damar jin daidai, da kuma damar jagoranci a kan matsayin da aka samu rike. A halin yanzu, damar samun rike da kuma damar kawo rike suna zama daga cikin manyan abubuwan da ke jin daidai a cikin system na kwallon kashi na DC a wurin.

Saboda siffofin device na semiconductors, SS DCCBs (Solid-State DC Circuit Breakers) sun iya ba da damar jawabi da take da damar kawo kashi – hada da 1,000 takwasuwa uku da electromechanical breakers. ABB ta girma solid-state DC circuit breaker wanda ya da damar jawabi na tsawo, kudin da ya fi kyau, da kuma damar jawabi da ya fi tsawo, wanda zai iya ba da al'amuran da take da masu system na kwallon kashi na DC a wurin.

Wannan aikin ya faru ne saboda parallel connection of Si Reverse-Blocking IGCTs (RB-IGCTs), wanda Corporate Research a Lenzburg da kuma ABB Semiconductors suka gina, tare da metal-oxide varistors (MOVs) da suka zama da damar jawabi. RB-IGCT ita ce 1,000 takwasuwa uku da electromechanical contact, kuma ana gina shi don damar jawabi da ya fi kyau. MOVs masu damar jawabi suna iya kawo kashi da kisan inductive energy na system da kuma damar jawabi da ya fi tsawo.

Solid-state DC circuit breakers na high-current suna ba da damar jawabi da ya fi tsawo a cikin system na DC wanda suke da damar jawabi da ya fi kyau, baki daya da arc-free. Platform na aikin tana miri voltage na system hada 1,000 Vdc, tare da rated currents daga 1,000 A zuwa 5,000 A. Teknologi tana haɗa da kudin da ya fi kyau hada 99.8%, tare da 99.5% a cikin IGBT-based solutions. Solid-state breakers suna iya amfani da water-cooling don damar jawabi da ya fi kyau ko amfani da advanced two-phase cooling, wanda ke haɗa da air cooling, kuma ke haɗa da kudin da ya fi kyau, kuma ke haɗa da low installation da kudin da ya fi kyau da asset life.

Kudin da ya fi kyau tana haɗa da 70% uku da kudin da ya fi kyau a cikin solutions masu hawa. A lokacin da shekaru 10, zai iya haɗa da $200,000 a cikin ferries da kuma $1 million a cikin cruise ships. Wannan circuit breaker na zamani zai iya amfani da shi a cikin manyan applications, kamar battery energy storage systems, data centers, da kuma electric vehicle charging infrastructures. A halin yanzu, ABB ta samu project funding daga U.S. Department of Energy don gina DC circuit breakers a cikin electric vehicle charging applications. Solid-state circuit breakers zai iya haɗa da damar jawabi da ya fi kyau a cikin system na kwallon kashi, kudin da ya fi kyau, da kuma damar jawabi da ya fi tsawo, kuma zai iya haɗa da durability requirements na next-generation power grid.
