I-Low-Voltage Isolation Switch- CNAISO SGL

1.Kuyini iIswishi yokuhlukanisa ye-SGL ?

A: I-SGL AC load isolation switch isetshenziswa kabanzi ohlelweni lokusabalalisa kanye nohlelo oluzenzakalelayo lwezakhiwo, amandla kagesi, i-petrochemical, nezinye izimboni.ifanele i-AC 50hz, i-voltage elinganiselwe ibe ngu-660V, i-DC elinganiselwe i-voltage efika ku-440V, Ikalwe okwamanje ifike ku-3150A.

B: Izinhlobo eziningi zezakhiwo nokusebenza lapho isimo sokuvula nokuvala sokuxhumana sibonwa ngamafasitela.low-voltage isolator switch 3p load break break switch wenzhou switch

C: Kunezinhlobo eziningi zokushintshwa: ukusebenza ngaphakathi noma ngaphandle kwebhodi, imisebenzi yangaphambili noma engemuva, kukhona nokuxhumana ngemuva kwebhodi.low-voltage isolator switch 3p load break break switch wenzhou switch

D: Zonke izinto zokuxhumana ziyi-alloy yethusi ehlanganiswe nesiliva, futhi zinezindawo ezimbili zokuxhumana ezihlukene

E: Yiba sendaweni ethi “O”, ingakhiya isibambo ngezingidi ezintathu ngesikhathi esisodwa futhi ngaleyo ndlela ingagwema ukusebenza kwephutha.

2.Indlela yokukhetha i-iswishi yokuzihlukanisa?

2.1.Izinto zikagesi ezizihlukanisa zodwa ngokuvamile zibhekisela ezintweni zamanje ezivaliwe ezingalayishi, ezingavula futhi zivale ama-currents angalayishi kuphela.Izinto ezisetshenziswayo zokuzihlukanisa zinezinkomba ezisobala zokucisha, njengamaswishi okuzihlukanisa, amafuse, amaswishi efuse yommese, namapulaki nezixhumi zesokhethi.njll., ingasetshenziswa njengezinto zikagesi zokuzihlukanisa.

2.2.Ukuze kugcinwe futhi kuhlolwe kangcono kanye nezidingo zokulungiswa kabusha nokuphepha, iswishi yokuhlukanisa kufanele ihlangabezane nezidingo zokuzihlukanisa, futhi izophinde ivikele into esebenza ngogesi uma ihlangabezana nesekhethi emfushane.Ingabuye ibizwe ngokuthi umshini ohlukanisayo.Iswishi yokuhlukanisa kufanele ifakwe eduze kwento esetshenziswayo yokulawula .

2.3.Iswishi yokuhlukanisa kufanele ihlangabezane ne-voltage elinganiselwe yesekethe kanye nezidingo zamanje okubaliwe, futhi i-standstand current kufanele ihlolwe ngokuvumelana namanani esikhathi esifushane kanye namanani aphezulu.Uma kunesidingo sekhono lokuvala, amandla ayo okuphuka kufanele abe mkhulu kunomsinga olindelekile weluphu.

2.4.Lapho inkinobho yokuhlukanisa ekhethiwe isetshenziselwa ukufaka izinto zikagesi ezihlukanisayo, indawo ephakathi yesibambo ayikwazi ukunqamula umthamo wamanje.Ezinye izinhlobo zokushintsha okuhlukanisayo zinganqamula umthamo wamanje ohambisanayo, kodwa inkinobho yommese enekhava ye-arc kufanele ikhethwe..

3.Injongo eyinhloko ye ukuhlukanisa ukushintsha?

3.1.Isetshenziselwa ukuhlukanisa ukunikezwa kwamandla nokunqamula okokusebenza kokulungisa amandla kagesi aphezulu emishinini ephilayo, ukuze kube nendawo esobala yokunqamula phakathi kwazo.

3.2.I-isolation switch isebenzisana ne-circuit breaker, futhi yenza umsebenzi wokushintsha ngokuya ngezidingo zemodi yokusebenza yesistimu ukuze uguqule imodi yezintambo zokusebenza kwesistimu.

3.3.Isetshenziselwa ukuxhuma noma ukunqamula amasekhethi amancane amanje.

3.4 Iswishi yokuhlukanisa ingenza le misebenzi elandelayo: ingadonsa futhi ivale i-bypass current yeswishi yesiyingi esivaliwe;donsa futhi uvale intambo yaphansi yephoyinti elingathathi hlangothi le-transformer, kodwa lapho iphuzu elingathathi hlangothi lixhunywe ngekhoyili yokucindezela i-arc, ingenziwa kuphela uma isistimu ingenaphutha.Ukusebenza;donsa futhi uvale ama-voltage transformer kanye nezibambisi;donsa futhi uvale i-busbar kanye ne-capacitor current yemishini exhunywe ngqo ku-busbar;donsa futhi uvale umugqa ongalayishi nge-capacitor yamanje engadluli ama-amps ama-5;umshini wokuhlukanisa izindlela ezintathu ungadonsa futhi uvale i-voltage ku-10 kV nangaphansi, ulayishe okwamanje ngaphansi kwe-15A, njll. Uma usebenzisa inkinobho yokuhlukanisa, kufanele kuqashelwe ukuthi lapho umugqa ukhanyisa, inkinobho yokuhlukanisa ebhasini. uhlangothi luvaliwe kuqala, khona-ke inkinobho yokuhlukanisa ohlangothini lomugqa ivaliwe, bese i-breaker circuit ivaliwe.Lapho ulayini ucishiwe, i-breaker yesifunda kufanele inqanyulwe kuqala, bese isishicileli sokuhlukanisa kufanele sikhishwe.Ungadonsi noma uvale iswishi ehlukanisayo ene-voltage ephezulu enomthwalo.

4.Kungani u-Yueqing AIso?

4.1: Ubunjiniyela obugcwele nokusekelwa kobuchwepheshe: abakhiqizi abangochwepheshe abangu-3, ​​nethimba lesevisi yezobuchwepheshe.

4.2: Ikhwalithi ingu-No1, isiko lethu.

4.3: Izikhathi zokuhola ngokushesha:“Isikhathi siyigolide” kuwe nakithi

4.4: 30min impendulo esheshayo: sineqembu lochwepheshe, 7 * 20H

Thola ukwethenjwa kweklayenti ngenxa yedumela labo elifakazelwe lokuthembeka, ukusebenza nempilo ende.

Uma unombuzosnoma yiziphi izidingo zomkhiqizo, sicela ukhululeke ukuxhumana nami.
