Iyo bushing dhizaini pane substation transformers haina kupusa senge mabhushi ari padmount transformers. Mabhuni ari padmount anogara ari mukhabhineti pamberi peyuniti ine yakaderera-voltage bushings kurudyi uye yakakwirira-voltage bushings kuruboshwe. Substation transformers inogona kuva nemabhushi anowanikwa chero kupi pane unit. Chii chimwe, zvichienderana nekushandiswa chaiko, kurongeka kwe substation bushings kunogona kusiyana.
Zvese izvi zvinoreva kuti kana iwe uchida substation transformer, ita shuwa kuti unoziva chaiyo bushing marongero usati waisa odha yako. Ramba uchifunga nezvekufamba pakati petransformer nemidziyo yauri kubatanidza nayo (breaker, nezvimwewo) Iyo bushing marongero inofanira kunge iri mufananidzo wegirazi, kwete kufanana.
Nzira yekusarudza marongerwo emakwenzi
Pane zvinhu zvitatu:
- Nzvimbo dzeBushing
- Phasing
- Terminal Enclosures
Nzvimbo dzeBushing
IAmerican National Standards Institute (ANSI) inopa zita repasi rose rekunyora mativi eshanduko: ANSI Side 1 ndiyo "kumberi" kweshanduko-divi rechikamu chinobata vharafu yekudhonza uye nameplate. Mamwe mativi anotarwa achifamba achitenderedza yuniti: Yakatarisana nechemberi kwetransformer (Side 1), Side 2 idivi rekuruboshwe, Side 3 idivi rekumashure, uye Side 4 idivi rekurudyi.
Dzimwe nguva substation bushings inogona kunge iri pamusoro peiyo unit, asi kana zvakadaro, ivo vanozorongedzerwa kumucheto kwerimwe divi (kwete pakati). The transformer's nameplate ichava netsanangudzo yakazara yebushing marongerwo ayo.
Substation Phasing
Sezvauri kuona mune substation inoratidzwa pamusoro, iyo yakaderera-voltage bushings inofamba kubva kuruboshwe kuenda kurudyi: X0 (iyo isina kwayakarerekera bushing), X1, X2, uye X3.
Nekudaro, kana kupatsanurwa kwaive kwakapesana nemuenzaniso wapfuura, marongerwo aizodzoserwa kumashure: X0, X3, X2, uye X1, ichifamba kubva kuruboshwe kuenda kurudyi.
Iyo isina kwayakarerekera bushing, inoratidzwa pano kuruboshwe, inogonawo kuwanikwa kurudyi. Iyo yekusarerekera bushing inogonawo kunge iri pasi pemamwe mabhushi kana pachivharo che transformer, asi nzvimbo iyi haina kunyanya kuwanda.
Terminal enclosures
Nekuchengetedza chero munhu angangosangana neshanduko, mirau inoda kuti ese materminal aiswe kunze kwekusvikirwa. Uyezve, kunze kwekunge mabhushi akatemerwa kushandiswa kwekunze-senge mabhushi akaiswa pamusoro-anofanirawo kuvharirwa. Kuve neiyo substation bushings yakavharwa inochengeta mvura nemarara kubva kune mhenyu zvikamu. Mhando nhatu dzinonyanya kuzivikanwa dze substation bushing enclosures ndeye flange, huro, uye air terminal chamber.
Flange
Flanges anowanzo shandiswa sechikamu chekubatanidza kubhaudhi pamhepo terminal kamuri kana chimwe chikamu chekuchinja. Sezviri pamufananidzo pazasi, transformer inogona kupfekwa neyakakwana-kureba flange (kuruboshwe) kana chidimbu-kureba flange (kurudyi), iyo inopa chinongedzo chaunogona bhaudhi chikamu chekuchinja kana bhazi duct.
Huro
Huro inenge yakawedzera flange, uye sezvauri kuona pamufananidzo uri pazasi, inogona zvakare kubatana yakananga kune bhazi duct kana chidimbu che switchgear, senge flange. Huro dzinowanzowanikwa padivi re-low-voltage ye transformer. Izvi zvinoshandiswa kana iwe uchida kubatanidza bhazi rakaoma zvakananga kune spades.
Huro
Huro inenge yakawedzera flange, uye sezvauri kuona pamufananidzo uri pazasi, inogona zvakare kubatana yakananga kune bhazi duct kana chidimbu che switchgear, senge flange. Huro dzinowanzowanikwa padivi re-low-voltage ye transformer. Izvi zvinoshandiswa kana iwe uchida kubatanidza bhazi rakaoma zvakananga kune spades.
