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.
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.
