KYN61-40.5 mtundu wazitsulo-wovala zitsulo zamtundu wa AC zitsulo-zotsekedwa switchgear (pambuyo pake zimatchedwa "switchgear") zimadziwika kwambiri ndi kugwiritsa ntchito ZN85-40.5 zowonongeka zowonongeka zowonongeka ndi machitidwe opangira masika mu nduna, ndi thupi la nduna. amasonkhanitsidwa ndi pulasitiki TACHIMATA zitsulo, amene bwino mafananidwe mwatsatanetsatane wa VCB ndi nduna. VCB ndiyosavuta kukankhira ndikutulutsa ndipo imakhala yosinthika mwamphamvu ndi mawonekedwe okongola, mayankho athunthu, kugwiritsa ntchito kotetezeka komanso kodalirika.
Izi zimagwiritsidwa ntchito mu 35kV magawo atatu amagetsi a AC 50Hz. Amagwiritsidwa ntchito kulandira ndi kugawa mphamvu zamagetsi m'mafakitale amagetsi, malo ocheperako komanso zipinda zogawa mphamvu zamabizinesi amakampani ndi migodi. Ili ndi ntchito zowongolera, zoteteza komanso zowunikira. Zogulitsa izi zimagwirizana ndi miyezo: GB3906 "Zosintha zachitsulo zotsekeredwa pakali pano ndi zida zowongolera zamagetsi ovotera pamwamba pa 3.6kV mpaka komanso kuphatikiza 40.5kV", GB/T11022 "Zodziwika bwino zama switchgear apamwamba kwambiri ndi zowongolera", DL/ T404 "Alternating-current zitsulo-otsekeredwa switchgear ndi controlgear oveteredwa voteji pamwamba 3.6kV ndi mpaka ndi kuphatikizapo 40.5kV", IEC60298 "AC zitsulo-otsekeredwa switchgear ndi controlgear oveteredwa voteji pamwamba 1 kV ndi mpaka ndi kuphatikizapo 52kV".
Kagwiritsidwe Ntchito Bwinobwino
● Kutentha kwa mpweya wozungulira: -15℃~+40℃.
● Chinyezi:
Chinyezi chapakati pa tsiku ndi tsiku: ≤95%, kuthamanga kwa mpweya wamadzi tsiku lililonse ≤2.2kPa.
Chinyezi chapakati pamwezi ndi 90%, ndipo mphamvu ya mwezi uliwonse ya nthunzi yamadzi ndi 1.8kPa.
● Kutalika: ≤4000m.
● Kuchuluka kwa chivomezi: ≤8 madigiri.
● Mpweya wozungulira sayenera kuipitsidwa ndi mpweya woyaka kapena woyaka, mpweya wamadzi, ndi zina zotero.
● Malo osagwedezeka kwambiri.

Kapangidwe
Mankhwalawa amagawidwa m'magawo awiri: nduna ndi VCB. Kabatiyo imapangidwa ndi mbale yopindika yachitsulo ndikusonkhanitsidwa ndi mabawuti pambuyo kupopera mbewu mankhwalawa. Malinga ndi magwiridwe antchito, imatha kugawidwa m'magawo anayi: chipinda chaching'ono cha basi, chipinda cholumikizira zida, chipinda cha VCB, chipinda cha chingwe ndi chipinda cha basi, gawo lililonse limasiyanitsidwa ndi kugawa kwachitsulo. Digiri yachitetezo cha mpanda wa switchgear ndi IP4X; pamene chitseko cha chipinda cha VCB chatsegulidwa, digiri ya chitetezo ndi IP2X.
Switchgear ili ndi machitidwe akuluakulu ozungulira monga chingwe cholowera ndi chotulukira, cholowera pamwamba ndi kutuluka, kulumikiza mabasi, kulumikiza, transformer yamagetsi, ndi chomangira mphezi. Busbar imagwiritsa ntchito kusungunula kophatikizana, ndipo ma inter-phase ndi zolumikizira amakhala ndi manja otchingira opangidwa ndi zinthu zoletsa moto. Makabati oyandikana ndi mabasi akuluakulu amasiyanitsidwa ndi manja a mabasi, omwe amatha kuteteza ngoziyo kuti isafalikire ndikuchita gawo lothandizira lothandizira mabasi akuluakulu. Chipinda cha chingwe chimakhala ndi switch switch, chipangizo choteteza ku overvoltage, etc.
Pali zitsulo zotetezera chitetezo kutsogolo kwa bokosi lolumikizana. Chotsekera chapamwamba ndi chotsika chachitetezo chimatsegulidwa pomwe VCB ichoka pamalo odulira / kuyesa kupita kumalo ogwirira ntchito, ndipo imatsekeka pomwe VCB ikupita kwina, ndikumachotsa pamagetsi apamwamba. The interlocking pakati lophimba waukulu, VCB, lapansi lophimba ndi nduna chitseko utenga kuvomerezedwa makina interlocking njira kukwaniritsa "zisanu kupewa" ntchito zofunika.
Wophwanyira dera amatengera makina opangira screw rod drive komanso clutch yopitilira. Makina opangira ma screw rod nut atha kugwiritsidwa ntchito mosavuta kusuntha VCB pakati pa malo oyesera ndi malo ogwirira ntchito. Mothandizidwa ndi katundu wodzitsekera wa screw rod nut, VCB ikhoza kutsekedwa modalirika pamalo ogwira ntchito kuti ateteze VCB ku ngozi yomwe imabwera chifukwa chothawa chifukwa cha mphamvu yamagetsi. Clutch yowonjezereka imagwira ntchito pamene VCB ikubwerera ku malo oyesera komanso ikafika pamalo ogwirira ntchito. Zimapangitsa shaft yogwirira ntchito ndi screw shaft kuti ingoyimitsa yokha ndikuyimitsa, zomwe zingalepheretse kusokoneza ndikuwononga makina odyetsa. Ma VCB ena amagwiritsa ntchito njira ya lever feed. Malo oyeserera amatsekedwa ndi zikhomo zoyika.
