Muaj ntau yam:
- Qhov chaw Bushing
- Phasing
Qhov chaw Bushing
Lub koom haum American National Standards Institute (ANSI) muab ib tug universal designation rau sau npe transformer sab: ANSI Sab 1 yog lub "pem hauv ntej" ntawm lub transformer-sab ntawm lub tsev uas hosts lub valve thiab nameplate. Lwm sab yog tsim los hloov clockwise nyob ib ncig ntawm lub chav tsev: Facing rau pem hauv ntej ntawm lub transformer (Sab 1), Sab 2 yog sab laug, Sab 3 yog sab nraub qaum, thiab Sab 4 yog sab xis.
Qee zaum substation bushings tuaj yeem nyob rau sab saum toj ntawm chav tsev, tab sis nyob rau hauv rooj plaub ntawd, lawv yuav tau nyob rau ntawm ntug ntawm ib sab (tsis nyob nruab nrab). Lub transformer lub npe daim ntawv yuav muaj tag nrho cov lus piav qhia ntawm nws bushing layout.
Phasing
Raws li koj tuaj yeem pom hauv substation duab saum toj no, cov hluav taws xob qis qis txav ntawm sab laug mus rau sab xis: X0 (qhov nruab nrab bushing), X1, X2, thiab X3.
Txawm li cas los xij, yog tias qhov phasing yog qhov txawv ntawm qhov piv txwv yav dhau los, qhov kev teeb tsa yuav thim rov qab: X0, X3, X2, thiab X1, txav ntawm sab laug mus rau sab xis.
Qhov nruab nrab bushing, duab ntawm no ntawm sab laug, tuaj yeem nyob rau sab xis. Qhov nruab nrab bushing kuj tseem nyob hauv qab ntawm lwm cov bushings lossis ntawm lub hau ntawm lub transformer, tab sis qhov chaw no tsis tshua muaj.
