Esona sizathu siphambili i-380V AC contactor itshisa kumandla-on ngenxa yokukhetha okungalunganga kombane wekhoyili. Umbane wekhoyili we-AC contactor kufuneka uhambelane nombane wombane.

Yintoni i-circuit breakers, i-switch switches kunye ne-disconnectors? Kucingelwa ukuba uninzi lwabasebenzi bombane bacace gca. Kodwa xa kufikwa kumahluko kunye nesicelo phakathi kwabaphuli beesekethe, ukutshintshwa komthwalo kunye nokuqhawula, abasebenzi abaninzi bombane banokwazi enye kodwa kungekhona enye, kwaye kwabanye abaqalayo bombane, abazi nokuba babuze ntoni. Sonke siyazi ukuba i-circuit breaker inokuvala, ithwale kwaye iphule ikhoyo ngoku phantsi kweemeko zesekethe eziqhelekileyo, kwaye inokuvala, ithwale kwaye iphule ikhoyo ngoku phantsi kweemeko zesiphaluka ezingaqhelekanga (kubandakanywa neemeko ezimfutshane) ngaphakathi kwexesha elithile. Ukutshintshwa komthwalo sisixhobo sokutshintsha phakathi kwe-breaker circuit kunye ne-sloating switch. Inesixhobo esilula sokucima i-arc, esinokuthi sinqumle umthamo olinganisiweyo womthwalo kunye nomthamo othile ogqithisiweyo, kodwa awukwazi ukunqumla i-short-circuit current.

Umnxibelelanisi we-AC licandelo lolawulo oluphakathi. Inzuzo yayo ixhomekeke ekukwazini ukudibanisa rhoqo kunye nokuqhawula imigca kunye nokulawula imisinga emikhulu ngamagalelo amancinci. Ukusebenza ngokubambisana ne-thermal overload relay nako kunokubonelela ngokhuseleko lomthwalo ogqithisiweyo kwisixhobo somthwalo. I-AC contactor sesona sixhobo sisetyenziswa kakhulu kwi-low-voltage control kulawulo oluzenzekelayo kunye neenkqubo zokuqhuba zombane.

I-POINT I / O yintsapho yeemodyuli zeemveliso ze-I / O ezifanelekileyo kwizicelo ezifuna ukuguquguquka kunye neendleko eziphantsi zobunini. Ngeemodyuli zokuxinana kweshaneli enye ukuya kwezisibhozo, kubandakanywa imodyuli ye-self-configuring discrete, i-modularity ye-POINT I / O inciphisa iindleko zenkqubo kunye nobukhulu. Ukukwazi ukuxuba umgangatho kunye ne-I / O ekhuselekileyo inikezela ngakumbi ukuguquguquka okukhulu kunye namathuba okulinganisa, kungakhathaliseki ukuba iimfuno zesicelo.

1. Umnxibelelanisi we-AC wamkela isixhobo sokucima ipleyiti ye-arc, ngelixa i-DC contactor ithatha isixhobo sokucima i-arc esivuthela ngokuvuthela.

Ulawulo lweemoto zeSchneider zoMbane kunye neemveliso zokhuseleko lweTeSys ziya kutshintshwa ngokusemthethweni kwimveliso entsha yombala omnyama omnyama nge-8 kaDisemba, 2021.
