Cov kev cai dav dav rau American -style prefabricated substations

(1) Rau cov teeb pom kev yooj yim thiab kev faib hluav taws xob rau pej xeem, siab -voltage metering tsis tas yuav tsum muaj nyob rau hauv qhov siab -voltage wiring scheme ntawm prefabricated substation; tsuas yog qis -voltage metering lossis tsis xav tau metering, thiab kev them nyiaj tsis tsim nyog. Muaj 4-6 qhov hluav taws xob tawm, tswj thiab tiv thaiv los ntawm cov khoom siv hluav taws xob yas.

(2) Rau lub zog hluav taws xob thiab teeb pom kev zoo rau pej xeem kev faib hluav taws xob, tus naj npawb ntawm cov hluav taws xob tawm hauv cov chaw ua haujlwm prefabricated nce mus rau 8-12. Tsis tas li ntawd, cov nyiaj them rov qab hluav taws xob yuav tsum tau muab.

(3) Tus kheej- tuav lub hwj chim thiab muaj xwm txheej tshwj xeeb.

Prefabricated substations muaj me me hneev taw. Feem ntau, prefabricated substation tsuas yog 5-6 square metres, thiab tseem tuaj yeem raug txo los ntawm 3-3.5 square meters. Haum rau cov chaw lag luam thiab cov mining uas hnyav hnyav, chaw nres nkoj, thiab thaj chaw nyob, nws txuas ntxiv siab -voltage fais fab mov mus rau qhov chaw thauj khoom, txo qis -voltage fais fab mov vojvoog, thiab txo qhov poob. Tsawg-voltage fais fab yuav tsum tau, feem ntau 4-6. Qhov no shortens lub sij hawm tsim kho ntawm qhov chaw thiab txo kev nqis peev.

Thaum siv cov cuab yeej tshiab xws li cov hloov pauv hloov pauv thiab SF6 hloov pauv, cov khoom siv tu lub voj voog tuaj yeem txuas ntxiv, thiab txawm tias kev saib xyuas - cov kev cai pub dawb tuaj yeem ua tiav. Cov tsos yog tshiab thiab zoo nkauj txaus nyiam, sib haum xeeb nrog ib puag ncig ib puag ncig ntawm substation. Lub tuam tsev fais fab hauv nroog xav tau siab -voltage metering rau tus kheej -tswj transformer substations (250kVA lossis 315kVA thiab siab dua). Qee qhov xwm txheej, muaj ntau lub voj voog tawm, suav nrog cov txheej txheem thaub qab. Hauv cov xwm txheej no, cov neeg tsim qauv muab cov kev siv hluav taws xob tiag tiag nrog kev siv rau cov qauv los ntawm cov tuam ntxhab kom ua kom zoo tshaj qhov tsim.
