Umehluko phakathi kwekilasi le-PC kanye nekilasi le-CB ekushintsheni kokudlulisa okuzenzakalelayo kanye namaphoyinti abalulekile wokukhetha

Amandla amabiliIswishi yokushintsha ngokuzenzakalelayoebizwa ngokuthiI-ATSE, Ukushintsha kokudlulisa okuzenzakalelayookokusebenza, okuvame ukwaziwa njengokushintshwa kwamandla amabili.Njengoba igama lisho, ixhunywe ngokuzenzakalelayo kugesi obekwe eceleni ngokusebenzisa inkinobho yamandla ephindwe kabili lapho amandla enqanyulwa ngokuzumayo, ukuze ukusebenza kwethu kungapheli, kuqhubeke nokusebenza.

I-YUYU ATS
Inhloso yeswishi yokudlulisa okuzenzakalelayo kwamandla amabili iwukusebenzisa indlela eyodwa evamile kanye nendlela yokulinda.Uma amandla avamile ehluleka noma ehluleka ngokuzumayo, ukushintsha kwamandla okumbaxambili kufakwa ngokuzenzakalelayo kumandla abekwe eceleni (ugesi obekwe eceleni unganikwa amandla yijeneretha ngaphansi komthwalo omncane) ukuze okokusebenza kusasebenza ngokujwayelekile.Okuvame ukusetshenziswa kakhulu amakheshi, ukuvikela umlilo, ukugadwa, kanye namandla angaphazamiseki ebhange e-UPS, kodwa isipele sakhe siyiphakethe lebhethri.

Lo mshini oshintshayo owusizo endaweni lapho kukhona abaningi, kubaluleke kakhulu ukuqinisekisa ukuthembeka kokunikezwa kwamandla okuphindwe kabili, abangani bakagesi kumele bazi ukuthi bangakhetha kanjani futhi bahlukanise kahle.

I-01, i-double power supply automatic switch level kanye nomehluko wezinga le-CB

Ikilasi le-PC: Uhlobo oluhlukanisiwe, njengeswishi yokujikijela imimese ephindwe kabili, enomshini wokusebenza, ingavula futhi iphathe isimanje esinephutha, kodwa hhayi ukunqamula umjikelezo wesifunda esifushane.Ukuqhubeka kokunikezwa kwamandla kungagcinwa lapho umthwalo ugcwele ngokweqile.Isikhathi sesenzo esisheshayo.Ukuthintana ne-alloy yesiliva, isivinini sokuhlukaniswa kokuxhumana, igumbi le-arc eliklanywe ngokukhethekile.Usayizi omncane, ingxenye kuphela yekilasi le-CB.

Isicelo: imanuwali - isetshenziselwa isiteshi sesisekelo sokuxhumana, isikrini sokuhlukanisa isikhungo samandla se-AC/DC;Ugesi - wamajeneretha edizili;Okuzenzakalelayo - okusetshenziselwa ukusatshalaliswa kwamandla, ukukhanyisa, ukuvikela umlilo nezinye izimo kumaphrojekthi wokwakha.

Uphawu lokuhlela (izinga le-PC)

Isigaba se-CB: Ikilasi le-CB lamukela i-circuit breaker njenge-actuator, ngokusekelwe kuma-breaker circuit amabili, alawulwa yisilawuli esinomshini wokudlulisa ugesi oxhumanisayo ukuze kubonakale ukuguqulwa okuzenzakalelayo kwezinto ezimbili zamandla, ukushintsha isikhathi 1-2s.Ifakwe idivayisi yokukhubeka ngokweqile, ukuxhumana kwayo okuyinhloko kungavulwa futhi kusetshenziselwe ukunqamula umjikelezo wesifunda esifushane.Inomsebenzi wokuvikela ukulayishwa okuchichimayo kwempahla kagesi eseceleni komthwalo kanye nekhebula, ingaxhuma, ithwale futhi iphule umjikelezo wesifunda esifushane, lapho umthwalo ubonakala ugcwele kakhulu noma umjikelezo omfushane, unqamule umthwalo.

Isicelo: sisetshenziselwa ukwakha ukusatshalaliswa kwamandla, ukukhanyisa, ukuvikela umlilo nezinye izikhathi zomthwalo ezingabalulekile;Isetshenziswa ezimakethe zezimboni (ezifana ne-metallurgy, i-petrochemical, isikhungo sikagesi, njll.), amaphrojekthi kaloliwe anesivinini esikhulu kanye nojantshi wesitimela nezinye izikhathi;Ingasetshenziswa futhi ne-master couplet.

02, ukunikezwa kwamandla okuzenzakalelayo kokukhetha amaphuzu okukhetha

I-1) Ngokombono wokuthembeka, izinga le-PC linokuthembeka okuphezulu kunezinga le-CB.Izinga le-PC lisebenzisa ukukhiya kwesenzo sokuguqula ngomshini +, kuyilapho izinga le-CB lisebenzisa ukukhiya kwesenzo sokuguqulwa kwe-elekthronikhi.
Kuze kube manje, ukushintshwa okuzenzakalelayo okuzenzakalelayo kwesigaba se-CB emhlabeni kwakhiwe ama-breaker circuit amabili, okuyisakhiwo esiyinkimbinkimbi kakhulu sazo zonke izinhlobo zezixazululo zokushintshwa okuzenzakalelayo kwamandla amabili (izingxenye ezihambayo zingaphezu kokuphindwe kabili kunesigaba se-PC esikabili. shintsha amandla okuzenzakalelayo).Ukuthembeka kokushintsha okuzenzakalelayo kwesigaba se-CB okuphindwe kabili kwamandla kuphansi kunaleyo ye-PC class amandla amabili okushintshwa okuzenzakalelayo (ngesizathu esifanayo sokuthi ukwethembeka kwe-circuit breaker kuphansi kunaleyo yokushintshwa komthwalo).

2) Isikhathi sokwenza umehluko wesikhathi sesenzo phakathi kwakho kokubili mkhulu, ukukhanyisa kokuphuma neminye imithwalo, ngokuyisisekelo kungasebenzisa izinga le-PC kuphela, ngoba isikhathi sokushintsha esidingekayo sifushane kakhulu.

3) Iswishi yamandla akabili yeleveli ye-PC ayinawo umsebenzi wokuvikela isifunda esifushane, ngakho-ke noma ukwengeza ama-breaker circuit kufanele kucatshangelwe ngokuvumelana nezidingo zesistimu yesekethe.Amandla okulayisha ngokweqile azodala imiphumela emibi yomugqa, ukuvikelwa kwawo kokulayisha ngokweqile akufanele kunqamule umugqa, kungenza esignali.Lapho ama-class CB ATses esetshenziselwa ukunikeza amandla emithwalweni yokulwa nomlilo, ama-atse ahlanganisa ama-breaker circuit anokuvikelwa kwesekethe emfushane kuphela azosetshenziswa.Ngakho-ke ukuze usindise izinkinga, umthwalo womlilo uvame ukusetshenziswa ezingeni le-PC.Ukushintsha amandla akabili indima yawo ukuzuza umsebenzi wokuguqula amandla amabili, awukho umsebenzi wokuvikela isifunda esifushane ongeke uthinte ukusebenza kwawo.Abantu abaningi bacabanga ukuthi umsebenzi wesifunda esifushane usetshenziselwa ukuvikela ukushintshwa, okuwukungaqondi kahle.

4) Ukuthi kusethwa yini iswishi yokuhlukanisa Ukufaka iswishi yokuhlukanisa kuzothatha isikhala, kwenyuse izindleko futhi kunciphise ukwethembeka.Kunconywa ukuthi inani lokushintshwa kokuhlukaniswa okufakwe ohlelweni lwamandla ezimboni kufanele lilawulwe, futhi akudingekile ukusetha inkinobho yokuhlukanisa endaweni yokuhlala.

5) Ikilasi le-PC: lingamelana namanje okulindelekile wesiyingi esifushane, lamanje elilinganiselwe alikho ngaphansi kuka-125% wamanje obaliwe.I-Class CB: Uma i-class CB ATses isetshenziselwa ukunikeza amandla emithwalweni yokulwa nomlilo, ama-atse ahlanganisa ama-breaker circuit anokuvikelwa kwesekethe emfushane kuphela azosetshenziswa.Ikilasi le-CB elishintshashintshayo lamandla amabili liyi-circuit breaker.Setha amapharamitha wokushintsha okuzenzakalelayo wekilasi le-CB ngokwezimiso nezindlela zokukhetha ama-breaker circuit.Uma ukhetha umkhiqizo, qinisekisa ukuthi ama-circuit breaker asetshenziswa umkhiqizo ahlangabezana nezidingo zendawo yokufaka.Ngokusekelwe kulezi zizathu ezingenhla, kunconywa ukuthi ukhethe i-MCCB enomsebenzi wokuvikela isifunda esifushane kuphela njengokushintshwa komzimba okuzenzakalelayo kwesigaba se-CB samandla amabili.Leli phuzu livame ukunganakwa, abaklami abaningi bakhetha i-CB class double power switch automatic, umaka kuphela imodeli yomkhiqizo, ibanga lamanje kanye nochungechunge, indiva uhlobo lwe-circuit breaker esetshenzisiwe, ukucaciswa, njll.
