1, Kev sib xyaw ua ke ntawm lub zog fais fab

(1) Lub zog fais fab

Raws li cov kev cai tshwj xeeb thiab kev lag luam

Ib lub tshuab ua ke hu ua lub tshuab fais fab. Lub tshuab fais fab kuj suav nrog cov relays kom ntseeg tau tias nws ua haujlwm tau zoo thiab ruaj khov.

Kev tiv thaiv thiab kev nyab xeeb lub cuab yeej tsis siv neeg, kev xa tawm automation, kev sib txuas lus thiab lwm yam kev pabcuam (tseem hu ua cov txheej txheem thib ob). Cov hauv paus ntawm Lub Tshuab Fais Fab

Lub luag haujlwm yog muab cov neeg siv lub zog txaus, txhim khu kev qha, tsim nyog thiab pheej yig.

(2) Lub zog fais fab network

Ib feem ntawm lub zog fais fab uas xa, hloov pauv thiab faib hluav taws xob hu ua lub zog fais fab. Lub zog fais fab suav nrog lub zog xa thiab faib hluav taws xob.

Lub vas sab.

Lub luag haujlwm tseem ceeb ntawm lub network kis tau yog kom nce qhov voltage los ntawm lub chaw fais fab deb ntawm qhov chaw thauj khoom los ntawm lub transformer thiab dhau

Cov kab hluav taws xob siab raug xa mus rau lub chaw nres tsheb hub uas nyob ib sab ntawm lub chaw thauj khoom. Tib lub sijhawm, cov kab hluav taws xob kuj txuas cov kab ke fais fab uas nyob ib sab thiab

Nws yog lub luag haujlwm ntawm cov chaw nres tsheb sib txuas.

Lub network faib khoom yog lub network fais fab uas faib hluav taws xob ncaj qha los ntawm lub chaw hloov pauv mus rau cov neeg siv. Feem ntau, lub network faib khoom tau muab faib ua qib siab

Voltage, nruab nrab voltage thiab qis voltage faib network. Hauv Suav teb, voltage ntawm high-voltage faib network feem ntau yog thiab ntawm nruab nrab voltage faib network

Lub zog ntawm cov khoom siv faib hluav taws xob qis feem ntau yog peb-theem plaub xaim system

2, Cov yam ntxwv ntawm kev ua haujlwm ntawm lub zog fais fab

Ua ntej, kev lag luam tag nrho loj heev. Tam sim no, cov cuab tam ntawm Tuam Tshoj txoj kev lag luam fais fab tau tshaj 200 billion, suav txog ib feem plaub ntawm tag nrho cov cuab tam ntawm lub xeev. Kev tsim hluav taws xob cuam tshuam ncaj qha rau kev txhim kho kev noj qab haus huv ntawm lub teb chaws kev lag luam.

Qhov thib ob yog tib lub sijhawm, seb lub zog hluav taws xob puas tuaj yeem khaws cia rau hauv ntau qhov, kev sib koom ua ke ntawm txhua qhov txuas tsis tuaj yeem faib ua ob, thiab cov txheej txheem hloov pauv sai heev. Lub zog tsim tawm hauv ib pliag yuav tsum sib npaug rau lub zog siv hauv ib pliag, yog li txhua qhov txuas ntawm kev tsim hluav taws xob, kev xa mus, thiab kev faib tawm rau cov neeg siv yog qhov tseem ceeb heev.

Qhov thib peb, kev tsim hluav taws xob yog qhov chaw nruab nrab thiab sib koom ua ke. Txawm tias muaj pes tsawg lub chaw tsim hluav taws xob thiab cov tuam txhab muab hluav taws xob, lub zog hluav taws xob yuav tsum tau sib koom ua ke hauv kev xa khoom, cov qauv kev tswj hwm thiab cov txheej txheem kev tswj hwm; Muaj cov kev cai nruj rau kev tsim khoom muaj kev nyab xeeb, kev qhuab qhia ntawm lub koom haum thiab kev coj ncaj ncees ntawm kev ua haujlwm.

Qhov thib plaub, kev siv tau. Cov hom phiaj kev pabcuam ntawm kev lag luam fais fab yog dav dav, koom nrog txhua tus neeg hauv zej zog. Qhov zoo ntawm lub zog thiab tus nqi muaj feem cuam tshuam nrog cov txiaj ntsig ntawm feem ntau ntawm cov neeg siv hluav taws xob.

Qhov thib tsib, lub teb chaws kev lag luam yuav tsum ua tus thawj coj hauv kev tsim hluav taws xob.

3, Rated voltage ntawm lub zog fais fab system

Qhov voltage ntawm lub hwj chim grid yog qib. Qhov rated voltage qib ntawm lub hwj chim grid yog tsim thiab tshaj tawm los ntawm lub xeev tom qab kev tshuaj xyuas thiab kev ua qauv qhia raws li qhov xav tau ntawm kev txhim kho kev lag luam hauv tebchaws, qhov laj thawj ntawm kev siv tshuab thiab kev lag luam, qib kev tsim khoom ntawm cov khoom siv hluav taws xob thiab lwm yam.

Tam sim no, qib AC voltage siab tshaj plaws hauv Suav teb yog 1000KV, uas tau muab tso rau hauv kev ua haujlwm ntawm Changzhi mus rau Jingmen thaum Lub Kaum Ob Hlis 30, 2008; Qib DC voltage siab tshaj plaws hauv Suav teb yog ntxiv lossis rho tawm 500KV, suav nrog Gezhouba - Shanghai Nanqiao Line, Tianshengqiao - Guangzhou Line, Guizhou - Guangdong Line, thiab Three Gorges - Guangdong Line.

Tam sim no, cov hluav taws xob siv ntau hauv Suav teb suav nrog 220V, 380V, 6kV, 10kV, 35kV, 110kV, 220kV, 330kV, 500kV thiab 1000KV. Ntawm lawv, cov kab hluav taws xob 10KV thiab qis dua hu ua cov kab faib hluav taws xob, thiab cov kab hluav taws xob 35KV thiab siab dua hu ua cov kab xa hluav taws xob. Nws kuj hais tias qhov hluav taws xob siab dua 1KV yog "qhov hluav taws xob siab", qhov hluav taws xob qis dua 1KV yog "qhov hluav taws xob qis", thiab qhov hluav taws xob kev nyab xeeb yog 36V thiab qis dua.

Qhov voltage uas ntsuas tau ntawm cov khoom siv hluav taws xob yog sib xws nrog lub zog fais fab. Qhov tseeb, vim yog qhov poob voltage hauv lub zog fais fab, qhov voltage tiag tiag ntawm txhua qhov chaw hloov pauv ntawm qhov ntsuas tau. Yuav kom ntseeg tau tias cov khoom siv hluav taws xob ua haujlwm zoo, nws yog qhov tseeb tias cov khoom siv hluav taws xob yuav tsum muaj qhov voltage ua haujlwm ib txwm dav dua li qhov kev hloov pauv ntawm lub zog hluav taws xob hauv lub zog fais fab. Qhov voltage ntsuas tau ntawm lub tshuab hluav taws xob feem ntau yog siab dua 5% ntawm qhov voltage ntsuas tau ntawm tib theem grid kom them rau qhov poob voltage ntawm lub zog fais fab.

Lub zog hluav taws xob uas ntsuas tau ntawm lub transformer muab faib ua cov windings thawj thiab cov windings thib ob. Rau lub winding thawj, thaum lub transformer txuas nrog qhov kawg ntawm lub grid, nws yog sib npaug rau qhov thauj khoom ntawm lub grid (xws li lub Hoobkas step-down transformer), yog li nws lub zog hluav taws xob ntsuas tau zoo ib yam li lub grid. Thaum lub transformer txuas nrog lub qhov hluav taws xob generator (xws li lub Hoobkas fais fab step-up transformer), nws lub zog hluav taws xob ntsuas tau yuav tsum zoo ib yam li lub generator. Rau lub winding thib ob, lub zog hluav taws xob ntsuas tau ntawm lub winding thib ob ntawm lub transformer yuav tsum siab dua 5% ntawm lub zog hluav taws xob ntsuas tau ntawm lub grid hauv kev xav txog nws tus kheej qhov poob hluav taws xob (xam los ntawm 5%) thaum lub transformer raug thauj khoom. Thaum qhov deb ntawm kev sib kis ntawm sab thib ob ntev, qhov poob hluav taws xob kab (xam los ntawm 5%) kuj yuav tsum raug txiav txim siab. Lub sijhawm no, lub zog hluav taws xob ntsuas tau ntawm lub winding thib ob yuav tsum siab dua 10% ntawm lub zog hluav taws xob ntsuas tau ntawm lub grid.
