Substations, raws li qhov txuas tseem ceeb hauv lub zog hluav taws xob, ua lub luag haujlwm tseem ceeb hauv kev hloov hluav taws xob high-voltage rau hauv hluav taws xob qis thiab xa mus rau ntau tus neeg siv. Yog li, substations ua haujlwm li cas?
Basic Cheebtsam ntawm substations
Substations yog tsim los ntawm cov hauv qab no qhov tseem ceeb:
1. Transformer:Qhov no yog cov khoom siv tseem ceeb ntawm lub substation.Lub transformersiv lub hauv paus ntsiab lus ntawm electromagnetic induction los hloov hluav taws xob high-voltage rau hauv hluav taws xob tsawg-voltage. Nyob rau hauv lub hwj chim system, lub transformer feem ntau yog muab faib mus rau hauv high-voltage sab thiab ib tug tsawg-voltage sab. Sab high-voltage tau txais hluav taws xob high-voltage los ntawm cov kab sib kis, thiab sab qis-voltage outputs lub converted hluav taws xob tsawg-voltage mus rau lub tis system.
2. Switchgear:Switchgear yog siv los tswj thiab tiv thaiv kev ua haujlwm ntawm lub zog hluav taws xob. Cov khoom siv no suav nrogCircuit Court breakers, disconnectors, load keyboards, thiab lwm yam. Circuit Court breakers tuaj yeem txiav tawm sai sai thaum muaj kev txhaum tshwm sim los tiv thaiv qhov txhaum ntawm kev nthuav dav; disconnectors yog siv los cais lossis txuas ntau qhov chaw ntawm lub voj voog; load keyboards yog siv los tswj lub on thiab off ntawm Circuit Court kom tau raws li lub zog thov ntawm txawv loads.
3. Cov khoom siv faib khoom:Cov khoom siv faib khoom yog lub luag haujlwm rau kev faib cov hluav taws xob hloov hluav taws xob qis rau ntau tus neeg siv. Cov khoom siv no suav nrog cov khoom siv faib khoom, cov tsheb thauj mus los, cov kab hluav taws xob, thiab lwm yam. Lawv tso tawm hluav taws xob hluav taws xob los ntawm cov hluav taws xob qis ntawm lub tshuab hluav taws xob thiab xa mus rau ntau qhov hluav taws xob qis, xws li cov nroog, cov zos, thiab kev lag luam thiab kev lag luam mining, los ntawm cov cables. los yog overhead kab.
4. Cov khoom siv tiv thaiv:Cov cuab yeej tiv thaiv yog siv los saib xyuas cov xwm txheej ntawm lub zog hluav taws xob thiab muab kev tiv thaiv thaum muaj kev ua txhaum. Cov khoom siv no tuaj yeem saib xyuas qhov tsis xws li tam sim no, voltage, thiab zaus hauv lub sijhawm. Thaum pom muaj qhov txawv txav lossis qhov tsis raug, qhov txhaum Circuit Court yuav raug txiav tam sim ntawd los tiv thaiv qhov txhaum ntawm kev nthuav dav thiab tiv thaiv kev nyab xeeb ntawm cov khoom siv hluav taws xob thiab cov neeg ua haujlwm.
5. Kev saib xyuas qhov system:Substations feem ntau kuj tau nruab nrog kev saib xyuas rau lub sijhawm saib xyuas thiab tswj xyuas cov xwm txheej ntawm lub zog. Lub kaw lus saib xyuas tuaj yeem saib xyuas ntau yam tsis muaj, suav nrog tam sim no, qhov hluav taws xob, lub zog hluav taws xob, thiab lwm yam, thiab muab cov haujlwm xws li tswb, ntsuas qhov yuam kev, thiab kev ua haujlwm nyob deb.
Txoj haujlwm ua haujlwm ntawm substation
Lub hauv paus ntsiab lus ntawm kev ua haujlwm ntawm lub substation tuaj yeem ua tiav hauv cov kauj ruam hauv qab no:
1. Tau txais lub zog hluav taws xob siab:Lub substation thawj zaug tau txais hluav taws xob high-voltage los ntawm cov kab sib kis. Lub zog no feem ntau nkag mus rau hauv substation los ntawm high-voltage alternating tam sim no (AC) kis kab.
2. Kev hloov hluav taws xob:Lub hwj chim tau txais high-voltage yog hloov mus rau qhov hluav taws xob los ntawm lub transformer. Lub transformer converts lub high-voltage hwj chim mus rau hauv tsawg-voltage hwj chim raws li lub teeb voltage piv. Nyob rau hauv cov txheej txheem no, lub transformer siv lub hauv paus ntsiab lus ntawm electromagnetic induction kom hloov lub zog hluav taws xob los ntawm high-voltage sab mus rau sab qis-voltage, yog li txo qhov voltage.
3. Fais fab kev faib tawm:Cov hluav taws xob hloov hluav taws xob qis hluav taws xob tau muab faib los ntawm cov khoom siv faib khoom. Cov khoom siv xa tawm xa cov hluav taws xob hluav taws xob mus rau txhua qhov qis-voltage load, xws li cov nroog, cov zos, thiab cov chaw lag luam thiab kev lag luam mining. Hauv cov txheej txheem no, cov khoom siv faib khoom yuav faib cov hluav taws xob hluav taws xob rau cov ceg sib txawv thiab cov khoom thauj raws li qhov sib txawv ntawm lub zog xav tau.
4. Kev saib xyuas thiab kev tiv thaiv:Thaum lub sij hawm cov txheej txheem ntawm kev hloov hluav taws xob hluav taws xob thiab kev faib tawm, cov cuab yeej tiv thaiv thiab kev soj ntsuam xyuas cov xwm txheej ntawm lub zog hluav taws xob hauv lub sijhawm. Thaum pom muaj qhov txawv txav lossis ua txhaum, cov cuab yeej tiv thaiv yuav txiav tawm qhov txhaum Circuit Court sai sai kom tsis txhob muaj qhov txhaum ntawm kev nthuav dav. Nyob rau tib lub sijhawm, lub kaw lus saib xyuas yuav tshaj tawm lub tswb thiab muab cov ntaub ntawv kuaj mob yuam kev kom cov neeg ua haujlwm tuaj yeem daws tau raws sijhawm.
5. Kev tu thiab kev tswj xyuas:Txhawm rau kom muaj kev ua haujlwm zoo ntawm lub substation, yuav tsum muaj kev saib xyuas thiab kev tswj xyuas tas li. Qhov no suav nrog kev tshuaj xyuas cov cuab yeej, kev sim, tu thiab lwm yam haujlwm. Nyob rau tib lub sijhawm, cov ntaub ntawv ua haujlwm txhua hnub, kev txheeb xyuas cov ntaub ntawv thiab lwm yam haujlwm tseem yuav tsum tau tshawb pom thiab daws cov teeb meem uas yuav tshwm sim.
Qhov tseem ceeb ntawm substations
Raws li lub hauv paus tseem ceeb ntawm lub zog hluav taws xob, qhov tseem ceeb ntawm substations yog qhov tseeb ntawm nws tus kheej. Nws tuaj yeem tsis tsuas yog hloov hluav taws xob high-voltage rau hauv hluav taws xob qis kom tau raws li cov kev xav tau ntawm cov neeg siv hluav taws xob, tab sis kuj tseem tiv thaiv kev nyab xeeb ntawm cov khoom siv hluav taws xob thiab cov neeg ua haujlwm. Hauv lub zog hluav taws xob, kev ua haujlwm ruaj khov ntawm lub substation yog ncaj qha ntsig txog kev nyab xeeb thiab kev ntseeg siab ntawm tag nrho cov system. Yog li ntawd, ntxiv dag zog rau kev saib xyuas thiab kev tswj hwm ntawm lub substation kom ntseeg tau tias nws cov kev ua haujlwm ib txwm muaj thiab txuas ntxiv nws lub neej kev pabcuam yog qhov tseem ceeb los xyuas kom muaj kev nyab xeeb thiab ruaj khov ntawm lub zog hluav taws xob.
