Roj Filled Fais Fab Transformer Installation Classification
Roj puv fais fab transformer muab faib rau sab hauv tsev thiab sab nraum zoov raws li qhov chaw installation.
Sab nraum zoov installation yog muab faib ua hom platform, ncej ntauwd hom thiab pem teb hom (nrog rau hom pre-ntsia).
1.1 ncej puab
Hom ncej-ntauwd yog txhawm rau txhim kho cov roj puv fais fab transformer ntawm tus ncej ntawm tus ncej. Muab faib ua ib tug pas nrig thiab ob tug pas nrig.
Thaum lub peev xwm ntawm cov roj ntim hluav taws xob hloov pauv yog 30KVA lossis qis dua (xws li 30KVA), feem ntau siv ib leeg-ncej transformer sawv ntsug. Txhim kho cov khoom siv hluav taws xob, lub zog hluav taws xob tso tawm hluav taws xob thiab cov khoom siv hluav taws xob siab rau ntawm tus ncej cement, thiab lub cev ncej yuav tsum tau inclined 13 degree -15 degree mus rau qhov sib txawv ntawm kev sib sau ua ke transformer.
Thaum lub peev xwm ntawm cov roj puv fais fab transformer nyob nruab nrab ntawm 50KVA thiab 315KVA, ob lub pas nrig faib transformer platform feem ntau yog siv. Lub platform transformer yog tsim los ntawm lub ntsiab pas nrig cement pas nrig thiab lwm tus pas nrig pab. Lub ntsiab pas nrig yog nruab nrog ib tug high-voltage drop-out fuse thiab ib tug high-voltage down-lead, thiab pab pas nrig muaj ib tug thib ob anti-lead hlau. Lub rooj sib txuas ob-ncej transformer muaj zog dua li ib-ncej tis transformer.
Qhov zoo ntawm cov ncej thiab ntauwd installation: kev ua haujlwm hauv av tsawg dua, tsis tas yuav muaj laj kab lossis laj kab nyob ib puag ncig, qhov chaw nyob yog qhov siab ntawm hauv av, thiab kev sib tsoo tsis yooj yim tshwm sim.
Disadvantages: ntau cov ntaub ntawv steel yog siv rau kev muag khoom, thiab tus nqi ntau dua.
1.2 Pier yam
Hom pier yog tsim lub 0.5-1m square pier nrog cib thiab pob zeb nyob rau hauv lub transformer ncej, thiab muab lub transformer rau nws. Feem ntau, transformers saum 315KVA raug ntsia.
Kev mloog yuav tsum tau them rau lub installation ntawm pier hom transformer:
(1) Ib lub laj kab lossis phab ntsa uas tsis pub tsawg dua 1.8m yuav tsum tau nruab ib ncig ntawm lub tshuab hloov pauv, thiab lub qhov rooj yuav tsum kaw thiab khaws cia los ntawm tus neeg tshwj xeeb.
(2) Yuav tsum muaj kev nyab xeeb txaus ua haujlwm nyob nruab nrab ntawm lub laj kab thaiv thiab lub laj kab thiab lub transformer.
(3) Cov cim ceeb toom xws li "muaj hluav taws xob txaus ntshai, tsis muaj kev nce siab" yuav tsum tau dai rau ntawm tus ncej lossis laj kab kom tsis txhob muaj neeg thiab tsiaj txhu los ze.
Qhov zoo ntawm lub platform pier installation: tus nqi qis, yooj yim txij nkawm thiab kho. Qhov tsis zoo: Nws yuav siv ntau thaj av, thiab lub laj kab yuav tsum tau nruab ib ncig ntawm nws. Cov tsiaj me tau yooj yim nce mus rau qhov chaw nyob, thiab nws yooj yim rau kev puas tsuaj los ntawm sab nraud quab yuam.
1.3 pem teb hom
Hauv pem teb-sawv hom yog hais txog kev tso lub transformer ncaj qha rau hauv av, thiab cov high-voltage down-conductor, drop-out fuse thiab xob laim ntes yog tag nrho ntawm kab davhlau ya nyob twg ncej.
Pem teb-standing transformer installation yuav tsum xyuam xim rau:
(1) Txhim khu kev ruaj ntseg yuav tsum tau nruab ib ncig ntawm cov roj puv fais fab transformer, thiab lub qhov rooj yuav tsum kaw thiab khaws cia los ntawm tus neeg tshwj xeeb.
(2) Cov cim ceeb toom xws li "High Voltage Danger, Tsis Tau Txais" yuav tsum tau dai sab nraum lub laj kab.
(3) Vim tias qhov muaj sia nyob ntawm cov roj puv fais fab transformer qis heev los ntawm hauv av, nws yuav tsum raug txiav tawm ua ntej nkag mus rau hauv lub laj kab.
