I-AISO Electric Supplier FLN36 SF6 I-Gas Load Break Switch

1.Ukubuka konkekwelayisha ukushintsha

I-FLN yohlobo lwe-indoor high voltage AC breaker switch ibhekisela kubuchwepheshe obusha bamazwe ngamazwe futhi ithuthukise imishini yokushintsha ngokuvumelana nezindinganiso ezifanele ohlelweni lwamandla kagesi lwaseChina.Izinkomba zokusebenza kwayo ngokuhambisana ngokugcwele ne-IEC420,694,129 namazinga kazwelonke GB3804-2004“3.6kV-0.5kV high voltage AC load breaker switch”GB1985-2004“high-voltage AC isolation switch and earthing switch”,GB/ T11022-199“ izidingo zobuchwepheshe ze-high-voltage switchgear kanye namazinga wempahla yokulawula“, Lena into eyinhloko yokushintsha i-RMU.I-load breaker switch iyiqoqo le-multifunctional medium voltage switchgear lamasango, isango elingaphansi, i-earthering.Endaweni evalwe ngokugcwele ngokuqiniswa kwesakhiwo sezindlu ze-epoxy resin ukuze kugcwaliswe igesi ye-SF6, 0.05MPa, enezingxenye ezincane zokufeza le misebenzi emithathu engenhla, ukuqinisekisa ikhwalithi yomkhiqizo, ukuthuthukisa ukwethembeka, ukungakhathalelwa.Ingaqhutshwa ngokuphepha iminyaka engaphezu kwengu-20 ezimeni ezijwayelekile.

2.Imisebenzi Eyisisekelo Nezicikwelayisha ukushintsha

2.1. Iswishi ye-load breaker ivumelanisa ukuphuka okuphindwe kabili, isakhiwo sokuxhumana esinyakazayo, nezinhlobo ezintathu ezilandelayo zezimo zokusebenza: Ukuvala, ukuvulwa, ukubeka umhlabathi.

2.2. Ukusebenzisa igesi ye-SF6 njengendlela yokucima i-arc kanye ne-insulating medium, i-circuit main seal by the top and low house ethela epoxy resin, umsebenzi we-conductive awuthintwa amathonya angaphandle.

2.3.Ukusebenza kahle kokuphepha.Uma i-arcing yangaphakathi yenzeka, indlu inesakhiwo sangaphakathi esibuthakathaka, izosheshiswa ukuvula, kulandelwa ikhabethe elingaphezulu kwe-shutter release arc ebomvu yomoya ovulekile wokucindezela umfudlana ngaphandle kwekhabhinethi, uqinisekise ukuthi ukushintshwa

amasheke ezokuphepha ekhabhinethi.

2.I-4.I-switch breaker switch isetha amasango, ukuvulwa, ukushintshwa komhlaba okuthathu kwesinye, okugcwele igesi ye-SF6 efakwe ku-epoxy resin housing, i-interlock enezikhundla ezintathu, isakhiwo esihlangene, ukuphepha okuphezulu nokuthembeka.

2.5.Usayizi omncane, isisindo esilula, ukunakekelwa-mahhala, kulula futhi kuphephile ukusebenza.

3.Ukuxhumana okulungile kwelayisha ukushintshakanye ne-fuse 

3.1 Umehluko oyisisekelo phakathi kweswishi yokulayisha kanye ne-fuse ukuthi i-fuse inamandla okunqamula i-short-circuit current, kuyilapho iswishi yokulayisha isebenza kuphela njengeswishi yamanje yokulayisha.Ngokuvamile kukholakala ukuthi inkinobho yokulayisha ivala futhi ihlukanise ukusebenza kwamanje, futhi i-fuse ivula i-current-circuit current.Kodwa-ke, lapho iphutha lenzeka, ngenxa yokuthi i-curse yezigaba ezintathu ayifani ngempela kanye nephutha lama-fuse, umehluko wesikhathi se-fuse phakathi kwama-fuse wezigaba ezintathu awunakugwemeka.Ngemuva kokuthi undunankulu esuse iphutha, uma ukushintshwa komthwalo kungakwazi ukuphula umthamo wamanje ngesikhathi, kuzobangela ukudlulisa ukusebenza kwamanje kanye nezigaba ezimbili, okubangela ukulimala kwemishini enamandla.I-fuse ene-striker, ehlanganiswe ne-switch switch nedivaysi yokukhubeka, ingaxazulula inkinga yokuntuleka kokusebenza kwesigaba.Lapho i-fuse ye-fuse incibilika, idivayisi yokugibelisa ukushintsha komthwalo inqanyulwa ngokushesha ngaphansi kokusebenza komgadli.Abakhiqizi basebenzisa kakhulu ukuxhumana kwamabha amane.Lapho inkinobho yokulayisha ivaliwe, iziphethu zokuvala nokuvula zigcina amandla ngesikhathi esifanayo.Lapho ukuxhumana kwamabha amane kudlula iphuzu elifile, amandla entwasahlobo yokuvala akhululwa, futhi inkinobho ivaliwe.Amandla we-brake spring asagcinwe yi-half-shaft mechanism.Uma umgadli eshaya, i-half-shaft iyanqanyulwa, amandla entwasahlobo yokuvula akhululwa, futhi inkinobho iyasebenza.Ngakho-ke, ama-fuse aneziteleka namaswishi okulayisha anemishini yokukhubeka kufanele kukhethwe asetshenziswe.

3.2 Kufanele kuphawulwe ukuthi amafuse asetshenziswayo asetshenziswa kakhulu njengamafuse okuvikela isipele.Le fuse ine-breaking current encane, ephindwe izikhathi ezingu-2.5 kuya kwezi-3 kunesilinganiso samanje se-fuse.Uma ingaphansi kwamandla amanje aphukayo, i-fuse eyisipele ayikwazi Ukunqamula lokhu kwamanje, okuyikhona okuyehlukanisa nefuse enobubanzi obugcwele.I-fuse yobubanzi obugcwele ingakwazi ukwephula ngokuthembekile noma yimaphi amandla akhona phakathi kokuncibilika kwamandla amanje kanye ne-breaking current (40kA), kodwa iyabiza.Uma iphutha lamanje lingaphansi komthamo omncane wokuphuka wefuse eyisipele, nakuba i-fuse ingenakukuqinisekisa ukuphuka kwayo, i-fuse izoshaywa, i- impactor kumemori yayo izoshaywa, futhi ukushintsha komthwalo womthelela kuzophulwa.Isibonelo, i-fuse ene-current elinganiselwe ye-100A ine-breaking current encane engaba ngu-250-300A.Kulesi sifunda samanje, i-fuse ayikwazi ukuphulwa, kodwa i-fuse iqhumisa umhlaseli, futhi ukushintshwa komthwalo womthelela kuyahamba, kuphule lokhu kwamanje, njengokuthi Uma inkinobho yokulayisha engu-600A ikhethiwe, ingaphazanyiswa ngendlela enokwethenjelwa.

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.
