Umahluko phakathi kweklasi yePC kunye neklasi ye-CB ekutshintsheni okuzenzekelayo kunye neengongoma eziphambili zokukhetha

Amandla amabiniUkutshintsha okuzenzekelayoekubhekiselwa kuyo njengeATSE, Ukutshintshela ngokuzenzekelaizixhobo, eyaziwa ngokuba ukutshintshwa kwamandla amabini.Njengoko igama lisitsho, iqhagamshelwe ngokuzenzekelayo kunikezelo lwamandla olulindileyo ngokutshintsha kwamandla kabini xa umbane ucinywa ngequbuliso, ukuze umsebenzi wethu ungayeki, unokuqhubeka nokusebenza.

YUYU ATS
Injongo yokutshintshwa kwamandla amabini ngokuzenzekelayo kukusebenzisa indlela enye eqhelekileyo kunye nendlela yokulinda.Xa umbane oqhelekileyo usilela ngequbuliso okanye usilela, umbane ophindwe kabini ufakwa ngokuzenzekelayo kunikezelo lwamandla olulindileyo (unikezelo lwamandla olulindileyo lunokuthi lunikwe amandla yijeneretha phantsi komthwalo omncinci) ukuze izixhobo zikwazi ukusebenza ngokuqhelekileyo.Ezona zisetyenziswa ngokuqhelekileyo zizinyusi, ukukhuselwa komlilo, ukucupha, kunye nonikezelo lwamandla olungaphazamisekiyo lwebhanki ye-UPS, kodwa i-backup yakhe yibettery pack.

Esi sixhobo sokutshintsha siluncedo kwindawo kukho ezininzi, kubaluleke kakhulu ukuqinisekisa ukuthembeka kombane ophindwe kabini, abahlobo bombane kufuneka bazi indlela yokukhetha ngokuchanekileyo kunye nokwahlula.

I-01, unikezelo lwamandla amabini oluzenzekelayo inqanaba lePC kunye nenqanaba le-CB umahluko

Iklasi yePC: Uhlobo olulodwa, njengokutshintsha kwemela ephindwe kabini, enesixhobo sokusebenza, inokusebenza kwaye iphathe isiqhelo kunye nesiphoso sangoku, kodwa hayi ukwaphula isiphaluka esifutshane.Ukuqhubekeka kokunikezelwa kwamandla kunokugcinwa xa umthwalo ugcwele kakhulu.Ixesha lesenzo esikhawulezayo.Ukuqhagamshelana ne-alloy yesilivere, isantya sokuhlukana koqhagamshelwano, igumbi le-arc elenziwe ngokukodwa.Ubungakanani obuncinci, kuphela isiqingatha seklasi ye-CB.

Isicelo: i-manual - isetyenziselwa isikhululo sesiseko sonxibelelwano, iplanti yamandla i-AC / DC isikrini sokuhlukanisa;Umbane - kwiijenereyitha zedizili;I-Automatic - isetyenziselwa ukuhanjiswa kwamandla, ukukhanya, ukukhuselwa komlilo kunye nezinye iimeko kwiiprojekthi zokwakha.

Isimboli yokucwangcisa (inqanaba lePC)

Iklasi ye-CB: Iklasi ye-CB ithatha i-circuit breaker njenge-actuator, esekelwe kwii-breakers ezimbini zeesekethe, ezilawulwa ngumlawuli kunye ne-mechanical interlocking transmission mechanism ukuze iqonde ukuguqulwa okuzenzekelayo kwezinto ezimbini zombane, ixesha lokutshintsha i-1-2s.Ukuxhotyiswa ngesixhobo sokuhamba nge-overcurrent, uqhagamshelwano lwayo oluphambili lunokutshintshwa kwaye lusetyenziswe ukuphula i-current circuit current.Inomsebenzi wokukhusela ogqithisiweyo wecala lomthwalo wezixhobo zombane kunye nekhebula, inokuxhuma, ithwale kwaye iphule isiphaluka esifutshane sangoku, xa umthwalo ubonakala ugqithise okanye ufutshane, unqamle umthwalo.

Isicelo: isetyenziselwa ukwakha ukuhanjiswa kwamandla, ukukhanya, ukukhuselwa komlilo kunye nezinye izinto ezingabalulekanga zomthwalo;Isetyenziswa kwiimarike zoshishino (ezifana nesinyithi, i-petrochemical, iplanti yamandla, njl.), iiprojekthi ze-high-speed kaloliwe kunye neeprojekthi zikaloliwe kunye nezinye iziganeko;Isenokusetyenziswa kunye ne-master couplet.

Isimboli yokucwangcisa (inqanaba leCB)

I-02, unikezelo lwamandla oluphindwe kabini amanqaku okhetho oluzenzekelayo

I-1) Ukususela kumbono wokuthembeka, inqanaba lePC linokuthembeka okuphezulu kunezinga le-CB.Inqanaba lePC lisebenzisa i-mechanical + conversion action lock, ngelixa inqanaba le-CB lisebenzisa isitshixo sokuguqula i-elektroniki.
Ukuza kuthi ga ngoku, iklasi ye-CB yamandla amabini okutshintsha okuzenzekelayo kwihlabathi yenziwe ngabaphuli beesekethe ezibini, esona sakhiwo sintsokothileyo sazo zonke iintlobo zamandla amabini azenzekelayo izisombululo zokutshintsha (amalungu ashukumayo angaphezulu kokuphindwe kabini kudidi lwePC ezimbini. amandla okutshintsha okuzenzekelayo).Ukuthembeka kweklasi ye-CB yamandla amabini okutshintsha okuzenzekelayo kungaphantsi kweklasi ye-PC yamandla amabini okutshintsha okuzenzekelayo (ngesizathu esifanayo sokuba ukuthembeka kwe-breaker sekethi kungaphantsi kunokokutshintsha komthwalo).

I-2) Ixesha lesenzo umehluko wexesha lesenzo phakathi kwezi zibini zinkulu, ukukhanyisa ukukhanya kunye neminye imithwalo, ngokusisiseko kunokusebenzisa inqanaba lePC kuphela, kuba ixesha lokutshintsha elifunekayo lifutshane kakhulu.

I-3) I-PC-level yamandla ombane we-PC ayinayo umsebenzi wokukhusela i-short-circuit, ngoko ke ukuba ukongeza ii-breakers ezongezelelweyo kufuneka ziqwalaselwe ngokweemfuno zenkqubo yesekethe.Amandla omthwalo ogqithisiweyo uya kubangela imiphumo emibi yomgca, ukukhuselwa kwayo ngokugqithisileyo akufanele kunqumle umgca, kunokusebenza kwisignali.Xa iiklasi ze-CB ATses zisetyenziselwa ukubonelela amandla kwimithwalo yokulwa nomlilo, i-atses equkethe i-circuit breakers kunye nokukhusela okufutshane kuphela kuya kusetyenziswa.Ke ukuze ugcine ingxaki, umthwalo womlilo usetyenziswa ngokubanzi kwinqanaba lePC.Ukutshintsha kwamandla amabini indima yawo kukuphumeza umsebenzi wokuguqula amandla amabini, akukho msebenzi wokukhusela omfutshane ongayi kuchaphazela ukusebenza kwawo.Abantu abaninzi bacinga ukuba umsebenzi wesiphaluka omfutshane usetyenziselwa ukukhusela iswitshi, nto leyo ukungaqondi kakuhle.

4) Ingaba ukuseta iswitshi yodwa Ukufakela umtshini wokuzihlukanisa kuya kuthatha indawo, ukwandisa iindleko kunye nokunciphisa ukuthembeka.Kucetyiswa ukuba inani lokutshintsha okukodwa okufakwe kwinkqubo yamandla oshishino kufuneka kulawulwe, kwaye akuyimfuneko ukuseta umtshini wokuzihlukanisa kumgangatho wokuhlala.

I-5) Iklasi ye-PC: inokumelana ne-short-circuit current elindelekileyo, i-current rated current ayikho ngaphantsi kwe-125% ye-current counted.Udidi lwe-CB: Xa iiklasi ze-CB ATses zisetyenziselwa ukubonelela amandla kwimithwalo yokulwa nomlilo, i-atses equkethe i-breaker circuit kunye nokukhusela isiphaluka esifutshane siya kusetyenziswa.Iklasi ye-CB yamandla amabini okutshintsha okuzenzekelayo ngokwenene i-breaker circuit.Cwangcisa CB iklasi ezimbini amandla utshintsho parameters oluzenzekelayo ngokwemigaqo kunye neendlela zokukhetha abaphuli beesekethe.Ukuba ukhetha uphawu, qinisekisa ukuba abaphuli beesekethe ezisetyenziswa yi-brand bahlangabezana neemfuno zendawo yokufakela.Ngokusekelwe kwezi zizathu zingasentla, kuyacetyiswa ukuba ukhethe i-MCCB enomsebenzi wokukhusela wesiphaluka esifutshane kuphela njengokutshintsha komzimba weklasi ye-CB yamandla amabini azenzekelayo.Eli nqaku lihlala lingahoywa, abaqulunqi abaninzi bakhetha iklasi ye-CB yamandla amabini okutshintsha okuzenzekelayo, phawula kuphela imodeli yemveliso, ibakala langoku kunye nochungechunge, ukungahoywa kohlobo lwesekethe esetyenzisiweyo, inkcazo, njl.
