Itandukaniro riri hagati y'igikoresho kirinda Surge n'ikirinda overvoltage

Ibikoresho birinda umuvuduko w'amashanyarazi n'ibirinda umuvuduko w'amashanyarazi ni ibikoresho bibiri bikoreshwa cyane mu kurinda ibikoresho by'amashanyarazi. Bishobora kugabanya cyangwa gusohora umuvuduko w'amashanyarazi w'igihe gito mu buryo bw'amashanyarazi no gukumira ko ibikoresho by'amashanyarazi byangirika bitewe n'inkuba cyangwa izindi mpamvu. Ariko, amahame ngiro yabyo, ibipimo by'imikorere, imiterere y'ikoreshwa ryabyo n'amahame y'igihugu byose biratandukanye. Iyi nkuru izagereranya kandi isesengure ibirinda umuvuduko w'amashanyarazi n'ibirinda umuvuduko w'amashanyarazi uhereye kuri ibi bice bine kugira ngo abasomyi babashe guhitamo neza no gukoresha ibi bikoresho bibiri birinda.

Igikoresho cyo kurinda Surge (SPD) ni igikoresho cy'amashanyarazi gifite voltage nkeya gikoreshwa muri sisitemu yo gukwirakwiza voltage nkeya kugira ngo kigabanye voltage nyinshi zihita zisohoka n'umuyoboro w'amashanyarazi usohoka. Igice cyacyo cy'ingenzi ni zinc oxide varistor (Metal Oxide Varistor, MOV), gifite imiterere ya voltage-current idahuje umurongo, ni ukuvuga iyo voltage ikoreshejwe iri munsi y'umurongo wayo, resistance yayo iba iri hejuru cyane kandi nta voltage inyura; Iyo voltage ikoreshejwe iri hejuru y'umurongo wayo, resistance yayo igabanuka vuba, inyura ku muyoboro munini w'amashanyarazi. Muri ubwo buryo, iyo voltage nyinshi ibaye mu muyoboro w'amashanyarazi, surge protector izahita ifungura kandi isohora voltage nyinshi ku murongo w'ubutaka, bityo ikarinda ibikoresho by'amashanyarazi bikurikira.

Ikingira Umuriro Urenze urugero (OVP) ni igikoresho gishobora guhagarika amashanyarazi mu buryo bwikora kandi vuba. Igice cyacyo cy'ingenzi ni sensor y'amashanyarazi (Voltage Sensor), ishobora kumenya impinduka z'amashanyarazi mu muyoboro w'amashanyarazi kandi igahuzwa n'umuyoboro w'amashanyarazi. Iyo voltage iri mu muyoboro w'amashanyarazi irenze urugero rw'amashanyarazi, umuyoboro w'amashanyarazi uzatangira gufunga umuriro kugira ngo uhagarike amashanyarazi, bityo urinde ibikoresho by'amashanyarazi bikurikira.
