Chimiro
● XGN-12 switch cabinet isimbi-yakavharwa bhokisi chimiro. Iyo furemu yekabati yakashongedzwa nesimbi yemakona. Iyo kabhineti yakakamurwa kuita kamuri yekupwanya yedunhu, imba yebhazi, kamuri yetambo, imba yekudzosera, nezvimwe, yakaparadzaniswa nemahwendefa esimbi.
● Imba yekutenderera yedunhu iri nechepasi pamberi pekabati. Kutenderera kwemutsigiri wedunhu kwakabatana nemaitiro ekushanda netambo yekusunga. Iyo yekumusoro wiring terminal yecircuit breaker yakabatana neyekumusoro disconnector, yakaderera wiring terminal yedunhu breaker yakabatana neyezvino transformer, uye ikozvino transformer yakabatana neiyo wiring terminal yepasi disconnector. Uye kamuri yekutyora yedunhu yakashongedzerwawo nekumanikidza kuburitsa chiteshi. Kana arc yemukati ikaitika, gasi rinogona kusunungura kumanikidza kuburikidza nemugero wekupedza.
● Imba yebhasi iri muchikamu chepamusoro chekumashure kwekabati. Kuti uderedze kureba kwekabati, mabhawa akarongedzerwa mu "pini" chimiro, anotsigirwa ne7350N bending simba porcelain insulators, uye mabhazi akabatana nepamusoro disconnector terminal, anogona kudimburwa pakati pemabhazi maviri ari padyo ekhabhineti.
● Imba yetambo iri kuseri kwechikamu chepasi chekabati. Iyo insulator inotsigira mukamuri yetambo inogona kuve yakashongedzerwa nemagetsi ekutarisa maturusi, uye tambo dzakaiswa pane bracket. Kune iyo huru yekubatanidza chirongwa, iyi kamuri ndiyo yekusangana tambo kamuri. Imba yekudzosera iri pamberi pekumusoro kwekabati. Iyo yemukati yekuisa bhodhi inogona kuiswa neakasiyana relays. Kune materminal block brackets mukamuri. Mukova unogona kuiswa nezvikamu zvechipiri zvakadai sekuratidza zviridzwa uye zvikamu zvechiratidzo. Iyo yepamusoro inogona zvakare kuve yakashongedzerwa neyechipiri diki bhazi.
● Nzira yekushanda yegumbo redunhu yakaiswa kuruboshwe rworuboshwe rwemberi, uye pamusoro payo ndiyo inoshandiswa uye inopindirana ye disconnector. Iyo switchgear ndeye kaviri-mativi ekugadzirisa. Izvo zvikamu zvechipiri zvekamuri relay, iyo yekuchengetedza inoshanda sisitimu, iyo mechanical interlocking uye transmission parts, uye circuit breaker inotariswa uye inogadziriswa kumberi. Iyo huru bhazi uye tambo terminals inogadziriswa kumashure, uye mwenje inoiswa mukamuri yekutyora yedunhu. Pazasi pemusuwo wepamberi panowanikwa bhawa yemhangura yekudzika inopindirana nehupamhi hwekabati, ine chikamu chemuchinjikwa che4X40mm.
● Mechanical interlocking: Kuti udzivise kusunungura nemutoro, kudzivirira kuvhurika kusina kunaka uye kuvhara kwevhavha yedunhu, uye kudzivirira nguva ine simba kuti ipinde nekukanganisa; kudzivirira kushanduka kwenyika nemagetsi kubva pakuvhara; kudzivirira kuvharwa kwepasi switch, switch kabati inotora inoenderana mechanical interlock.
Iyo mechanical interlock operation musimboti wecheni yakaita seiyi:
● Simba rekutadza kushanda (operation-overhaul): The switch cabinet iri panzvimbo yekushanda, kureva kuti, iyo yekumusoro uye yakaderera disconnector uye mabreaker circuit ari mukuvhara, magonhi epamberi uye kumashure akavharwa, uye ari kushanda. . Panguva ino, mubato muduku uri munzvimbo yekushanda. Kutanga vhura iyo yedunhu breaker, wozodhonza diki mubato kune "breaking interlock" chinzvimbo. Panguva ino, muparadzi wedunhu haagoni kuvharwa. Isa mubato wekushandisa mugomba repazasi redisconnector uye woridhonzera pasi kubva kumusoro kuenda pazasi disconnector yekuvhura chinzvimbo, Bvisa mubato, wobva waupinza muburi repamusoro rekudimburira oparesheni, woridhonzera pasi kubva kumusoro kuenda kumusoro kuvhura disconnector. chinzvimbo, wobva wabvisa mubato wekuvhiya, woupinza mugomba rekushanda wepasi switch, woisundidzira kubva pasi kuenda kumusoro kuita kuti pasi richinje munzvimbo yekuvhara, mubato mudiki unogona kudhonzwa kune "overhaul" chinzvimbo pano. nguva. Unogona kuvhura gonhi rekutanga, tora kiyi kuseri kwegonhi uye wovhura gonhi rekumashure. Mushure mekunge simba rekutadza kushanda kwapera, vashandi vekuchengetedza vanochengetedza uye kugadzirisa kamuri yekupwanya yedunhu nekamuri yetambo.
● Simba rekufambisa kushandiswa (kuwedzeredza-kushanda): Kana kugadzirisa kwapera uye simba richidiwa, maitiro ekushanda ndeaya anotevera: vhara kumashure, bvisa kiyi uye uvhare gonhi repamberi, uye fambisa mubato muduku kubva pa "overhaul". " chinzvimbo kune "disconnecting interlock" chinzvimbo. Kana gonhi repamberi rakakiyiwa uye muparadzi wedunhu haugone kuvharwa, isa mubato wekushandisa mugomba rekushandisa repasi switch uye woikwevera pasi kubva kumusoro kusvika pasi kuti pasi rishanduke panzvimbo yakavhurika. Bvisa mubato wekushandisa woipinza muburi rekushandisa rekudimbura. Sundidzira pasi uye kumusoro kuti ugadzire iyo yekumusoro disconnector munzvimbo yekuvhara, bvisa mubato wekushandisa, woipinza mugomba rekushandisa repazasi disconnector, uye sunda kubva pasi kumusoro kuti ugadzire rezasi disconnector munzvimbo yekuvhara, tora iyo inoshanda. bata, uye dhonza mubato diki kune chinzvimbo chekushanda, muparadzi wedunhu anogona kuvharwa.
● Chigadzirwa chakazara zviyero uye kudhirowa kwechimiro (ona Mufananidzo 1, Mufananidzo 2, Mufananidzo 3)
