1. Cov kev cai ntawm kev nyab xeeb rau kev xa tawm transformers ntsia rau txhua kab Qhov kev ncua deb ntawm lub hauv paus transformer thiab hauv av yuav tsum tsis txhob tsawg tshaj li 2.5m, thiab tag nrho cov hlau qhov chaw yuav tsum tau grounded. Qhov siab ntawm qhov nthuav tawm ntawm qhov av yuav tsum yog tsawg kawg 3.5m.
Lub hauv paus transformer yuav tsum tau tsau rau lub platform, thiab sab sauv yuav tsum tau tsau rau tus ncej nrog hlau fittings Lub sab sauv thiab qis ntawm transformer yuav tsum tau insulated nrog ntau yam strands ntawm hlau. Qhov kev ncua deb ntawm lub high-voltage tso tawm fuse thiab hauv av yuav tsum tsis txhob tsawg tshaj li 4m, thiab qhov deb ntawm nruab nrab thiab ntug theem ntawm high-voltage fuse yuav tsum tsis txhob tsawg tshaj li 0.5m. Lub kaum sab xis nruab nrab ntawm cov kab nruab nrab ntawm cov khoom siv ceramic ntawm high-voltage fuse thiab kab perpendicular yuav tsum yog 250-300 Daim ntawv ceeb toom nyeem 'Tsis Tau nce siab, Kev phom sij siab!' yuav tsum tau dai.
2. Kev nyab xeeb kev cai rau sab nraum zoov pem teb mounted faib transformers
Lub hauv paus ntawm lub hauv paus hloov pauv yuav tsum yog 0.2m saum av. Yog tias nws nyob hauv thaj chaw dej nyab, cov kav dej yuav tsum tau teeb tsa ib ncig ntawm lub tshuab hloov pauv; Lub laj kab cib thiab pob zeb yuav tsum tau teem ib ncig ntawm lub transformer, nrog qhov siab ntawm tsis pub tsawg tshaj 1.8m. Lub qhov rooj ntawm lub laj kab yuav tsum tau ua los ntawm cov ntaub ntawv refractory thiab tsim nyob rau sab qis-voltage ntawm transformer. Lub qhov rooj yuav tsum qhib sab nraud thiab kaw. Xyoob thiab ntoo laj kab yuav tsum tsis txhob siv.
Lub transformer yuav tsum tau ntsia nyob rau hauv ib tug pedestal (pier) style, thiab qhov siab ntawm lub pedestal (pier) yuav tsum tsis txhob tsawg tshaj li 2.5 m. ⑶ Thaum ob lossis ntau lub tshuab hloov pauv tau teeb tsa sab nraum zoov, qhov kev ncua deb ntawm lawv cov casings yuav tsum tsis pub tsawg dua 1.25m.
Lub transformer casing yuav tsum tau grounded kom zoo.
Qhov kev ncua deb ntawm lub transformer thiab combustible vaj tse yuav tsum tsis txhob tsawg tshaj li 5m, thiab qhov deb ntawm hluav taws kub-resistant vaj tse yuav tsum tsis txhob tsawg tshaj li 3m.
Dai cov cim ceeb toom nyeem 'Nres, muaj hluav taws xob txaus ntshai' ntawm phab ntsa lossis lub platform (piers).
3. Cov txheej txheem kev nyab xeeb rau cov khoom siv hluav taws xob hauv tsev: ⑴ Yuav tsum muaj qhov cua zoo hauv tsev. ⑵ Qhov hluav taws kub tsis kam ntawm chav tsev transformer yuav tsum yog qib ib.
Qhov kev ncua deb nruab nrab ntawm sab nrauv ntawm lub transformer thiab lub rear thiab sab phab ntsa yuav tsum tsis txhob tsawg tshaj li {{0}}.6m, thiab qhov deb ntawm lub qhov rooj yuav tsum tsis txhob tsawg tshaj li 0.8m; Lub qhov rooj thiab qhov rais ntawm chav tsev transformer yuav tsum qhib rau sab nraud, thiab yuav tsum muaj cov louvers hauv qab lub qhov rooj thiab qhov rais.
