Substations hloov hluav taws xob los ntawm siab mus rau qis, lossis rov qab, lossis ua ib qho ntawm ob peb lwm yam tseem ceeb. A substation tej zaum yuav muaj xws li transformers los hloov voltage theem ntawm high transmission voltages thiab qis tis voltages, los yog nyob rau hauv interconnection ntawm ob sib txawv kis voltages.
Hais txog qhov no, lub hom phiaj tseem ceeb ntawm lub substation yog dab tsi?
Cov lub hom phiaj ntawm lub substation yog kom 'qib nqis' hluav taws xob hluav taws xob siab los ntawm cov kab hluav taws xob xa mus rau hluav taws xob qis kom nws tuaj yeem muab tau yooj yim rau tsev thiab kev lag luam los ntawm peb cov kab xa khoom.
koj tsim ib lub substation li cas? Cov kauj ruam
- Tsim thaj chaw ua haujlwm.
- Npaj qhov chaw substation.
- Excavate thiab nteg lub hauv paus.
- Nruab daim phiaj hauv av.
- Ua lub tsev hais kom ua.
- Backfill lub hauv paus thiab substation vaj.
- Sib sau cov txheej txheem steel.
- Nruab cov khoom siv hluav taws xob.
Kuj paub, hluav taws xob substations ua haujlwm li cas?
Cov hluav taws xob yog kis tau ntawm high voltages thiab tsis tshua muaj tam sim no los txo cov cua sov, eddy tam sim no, thiab lwm yam kis tau tus mob poob. Cov substations yog qhov twg cov voltages tau nce mus rau qhov muaj txiaj ntsig zoo los ntawm kev siv cov kauj ruam nce transformers, thiab tom qab kis tau tus mob, lawv tau rov nqis los rau kev faib tawm.
Dab tsi yog qhov txawv ntawm substation thiab switchyard?
Ib qho kev hloov substation , los yog switchyard , yog a substation tsis muaj transformers uas ua haujlwm tsuas yog nyob rau ntawm ib theem voltage. Hloov chaw , siv feem ntau rau kev sib txuas thiab kev sib txuas, yog qhov tseem ceeb rau kev sib kis, kev xa tawm, kev sib sau, thiab kev tswj cov dej ntws ntawm hluav taws xob.
