Sab nraum zoov Switchyard (Substation)
Qhov chaw uas lub switchgear ntawm qhov chaw nres tsheb tau txais thiab faib cov hluav taws xob hluav taws xob uas tsim los ntawm lub tshuab hluav taws xob hydro-generator, thiab cov khoom siv hluav taws xob hluav taws xob muaj hluav taws xob muaj hluav taws xob xa hluav taws xob mus rau hauv kab hluav taws xob lossis qhov chaw thauj khoom tom qab boosting. Nws yog tsim los ntawm transformer, switchgear, rho tawm hloov, kev sib nrig sib inductor, xob laim ntes, busbar ntaus ntawv thiab lwm yam tsev qauv. Nws yog kis mus rau ib tug ntev deb ntawm lub switchyard.
Nws tuaj yeem muab faib ua ob pawg: sab nraum zoov thiab sab hauv tsev hluav taws xob faib khoom raws li qhov chaw teeb tsa ntawm cov khoom siv hluav taws xob. 110kV thiab 220kV cov khoom siv hluav taws xob tau teeb tsa hauv cov nroj tsuag thaum ua ke nrog cov yam ntxwv ntawm qhov chaw nres tsheb hydropower, thiab qhov sib txawv ntawm qhov sib txawv me dua qhov kev teeb tsa sab nraum zoov, yog li thaj chaw kuj tseem me me. Cov nqi tsim kho pej xeem yog siab dua qhov kev teeb tsa sab nraum zoov, thiab lub sijhawm tsim kho yog ntev dua, tab sis nws tsis cuam tshuam los ntawm huab cua phem. Qee lub sij hawm txhawm rau txo cov nqi tsim kho, ib feem ntawm cov cuab yeej tseem muab tso rau sab nraum cov nroj tsuag.
khoom Introduction
Cov lus qhia luv luv rau cov qauv ntawm qhov chaw nres tsheb boost hloov:
1. High-voltage Circuit Breaker: Nws tuaj yeem txiav tawm thiab txuas tsis muaj kev thauj khoom thiab thauj khoom tam sim no ntawm cov kab thiab ntau yam khoom siv hluav taws xob thaum lub cev ua haujlwm ib txwm muaj; Txhawm rau tiv thaiv kev nthuav dav ntawm qhov kev huam yuaj, Nws tuaj yeem koom tes nrog cov relay lav kom sai txiav tawm qhov txhaum tam sim no thaum lub kaw lus ua tsis tiav;
2. High-voltage Isolation Switch: Txhawm rau kom muaj kev nyab xeeb ntawm cov khoom siv hluav taws xob high-voltage thiab cov khoom siv ua lub luag haujlwm ntawm kev sib cais ntawm cov khoom siv hluav taws xob thaum lub sijhawm ua haujlwm, qhov kev rho tawm tsuas tuaj yeem qhib thiab kaw qhov tsis muaj hluav taws xob, thiab tsis ua haujlwm. muaj lub arc extinguishing muaj nuj nqi;
3. Tam sim no Transformer: Hloov siab tam sim no rau hauv qis tam sim no proportionally. Thawj sab ntawm lub tam sim no transformer yog txuas nrog lub hauv paus system, thiab lub thib ob sab yog txuas nrog rau kev ntsuas ntsuas, kev tiv thaiv relay, thiab lwm yam;
4. Voltage Transformer: Rau lub hom phiaj ntawm kev tiv thaiv, metering, thiab instrumentation, nws yog converted high voltage mus rau ib tug standard theem nrab voltage ntawm 100V los yog qis dua raws li ib tug proportional kev sib raug zoo;
5. Lightning Arrester: Nws yog siv los tiv thaiv ntau yam khoom siv hluav taws xob hauv lub zog hluav taws xob los ntawm kev puas tsuaj los ntawm xob laim overvoltage, kev khiav hauj lwm overvoltage, thiab lub hwj chim zaus zaus overvoltage. Tus neeg ntes feem ntau yog txuas nrog ntawm cov hlau nyob thiab hauv av, uas txuas nrog rau cov khoom siv tiv thaiv.
