Ntlafatsa polokeho ea hau ea indasteri ka li-circuit breaker tse nyane

Lefatšeng le matla la tikoloho ea indasteri, polokeho e fetohile ea bohlokoa.Ho sireletsa lisebelisoa tsa bohlokoa ho tsoa mefuteng e ka bang teng ea motlakase le ho netefatsa bophelo bo botle ba basebetsi ho bohlokoa.Mona ke moo li-circuit breakers (MCBs) li kenang teng.MCB e etselitsoe ho nepahala le ho sebetsa hantle, e nang le likarolo tse ngata tse etsang hore e be khetho e phethahetseng bakeng sa ts'ebetso ea ho itšehla thajana ea indasteri, potoloho e khuts'oane e kopaneng le ts'ireletso ea hajoale, le tse ling.Ha re ke re hlahlobeng ka botebo litšoaneleho tse tsotehang tse etsang hore MCB e be ntho eo motho a lokelang ho ba le eona bakeng sa raliindaseteri ofe kapa ofe ea nang le temoho.

MCB e lumellana le maemo a tsebahalang lefatšeng ka bophara a IEC/EN 60947-2 le IEC/EN 60898-1 mme e etselitsoe ho netefatsa ho tshwaneleha ho ke keng ha lekanngwa bakeng sa ho ikarola diindastering.Litekanyetso tsena li netefatsa hore li-MCB li khona ho hula motlakase ka mokhoa o sireletsehileng nakong ea tlhokomelo kapa maemong a tšohanyetso.Sena se tiisa tikoloho e bolokehileng ea ts'ebetso bakeng sa litsebi ha ho ntse ho sireletsa bohlokoa ba mochini.

Ha ho tluoa tabeng ea polokeho ea motlakase, potoloho e nyanemoqhobis ke khetho e tšepahalang.Likamore tsena tse nyane tsa motlakase li kenyelletsa ts'ireletso ea hajoale ea potoloho e khuts'oane le e boima, e leng bohlokoa haholo tikolohong ea indasteri.Li-MCB li khona ho lemoha kapele le ho sitisa phallo e sa tloaelehang ea hona joale, ho thibela tšenyo e ka bang teng ea lisebelisoa le ho fokotsa nako ea ho theoha nakong ea phoso.Karolo ena e fokotsa kotsi ea mello ea motlakase, e etsa hore sebaka sa hau sa indasteri se sireletsehe ho bohle.

Ho tenyetseha le ho ts'epahala ha MCB ho bonts'oa hape ke li-terminals tsa eona tse feto-fetohang.Ho kenya ho bonolo ka ho khetha pakeng tsa li-terminals tse sa sireletsehang kapa li-ring lug terminals.Li-terminals tsena li fana ka khokahanyo e sireletsehileng, e fokotsang kotsi ea lithapo tse hlephileng kapa li-arcing.Ho feta moo, li-terminals li hatisitsoe ka laser bakeng sa ho tsebahatsa kapele le khokahano e se nang liphoso, ho boloka nako le matsapa nakong ea ho kenya le ho lokisoa.

Ho boloka batho ba bolokehile ke ntho e tlang pele tikolohong efe kapa efe ea indasteri.MCB e fana ka li-terminals tse sireletsehileng tsa menoana tsa IP20 ho thibela ho kopana ka phoso.Tšobotsi ena e eketsa tšireletso e eketsehileng ho thibela ho tsosoa ha motlakase le kotsi.Ho phaella moo, MCB e kenyelletsa pontšo ea boemo ba ho ikopanya ho lumella ho khetholla habonolo boemo ba potoloho, ho netefatsa tlhokomelo e nepahetseng le ho rarolla mathata.

MCB e fana ka likhetho tsa ho ntlafatsa ts'ebetso ea sesebelisoa le ho e etsa.Ka tšebeliso ea lisebelisoa tse thusang, MCB e fana ka bokhoni ba ho beha leihlo hole, e lumellang basebelisi ho lekola le ho laola maemo a bona a indasteri ba le hole.Ntle le moo, li-circuit breaker tse nyane li ka ba le sesebelisoa sa hajoale (RCD) ho eketsa ts'ireletso ea ho lutla le ho netefatsa mehato e felletseng ea polokeho bakeng sa basebetsi le mechini.Ho feta moo, khetho ea ho kenyelletsa li-comb busbars e nolofatsa ts'ebetso ea lisebelisoa, e etsa hore e potlake, e be betere ebile e tenyetsehe.

Ka kakaretso, li-circuits tse nyane li loketse polokeho ea indasteri.Ho lumellana ha bona le litekanyetso tsa machaba, ts'ireletso e kopantsoeng ea potoloho e khuts'oane le boima bo feteletseng, likhokahano tse feto-fetohang, likarolo tse ntlafalitsoeng tsa polokeho le likhetho tsa ho iketsetsa li etsa hore e be tsa bohlokoa haholo tikolohong efe kapa efe ea indasteri.Ka ho kenyelletsa li-MCB ho sistimi ea hau ea motlakase, o ka ntlafatsa polokeho ea basebetsi, ho sireletsa lisebelisoa tse turang, le ho ntlafatsa
