Hluav taws xob substations yog qhov sib txuas ntawm qhov chaw ntawm daim phiaj sib faib thiab kev sib kis. Cov fenced tawm cov cheeb tsam no txo qis qhov hluav taws xob hauv cov kab sib kis mus rau ib qho uas tsim nyog rau daim phiaj sib faib. Lawv kuj tau nruab nrog cov hluav taws xob hluav taws xob los tiv thaiv qhov kev faib tawm, thiab tuaj yeem siv los tswj cov dej ntws ntawm cov dej ntws hauv ntau cov lus qhia. Lawv kuj du thiab lim voltage fluctuations tshwm sim los ntawm, piv txwv li, nce load.

Ib feem ntawm ib qho hluav taws xob substation
Transformer:Nws yog lub tshuab hluav taws xob zoo li qub uas ua haujlwm kom nce lossis txo cov hluav taws xob hauv AC hluav taws xob hluav taws xob, thaum tswj xyuas qhov zaus thiab lub zog.
Circuit Breaker:Nws cuam tshuam thiab rov tsim kho qhov txuas ntxiv ntawm hluav taws xob Circuit Court. Xws li kev cuam tshuam yog tsim los ntawm kev thauj khoom lossis luv luv tam sim no.
Recloser:Nws yog ib feem ntawm electromechanical uas cuam tshuam qhov tam sim no thaum muaj hluav taws xob ntau dhau thiab ua thaum muaj teeb meem tshwm sim hauv Circuit Court. Reclosers yog tsim los ua haujlwm nrog 3 kaw haujlwm thiab 4 qhov qhib nrog lub sijhawm nruab nrab ntawm lawv.
Hniav fuses:Lawv yog cov kev sib txuas thiab kev sib txuas ntawm cov hluav taws xob circuits nrog ob txoj haujlwm. Ntawm ib sab, raws li ib tug hniav disconnect, nws switches rau thiab tawm. Ntawm qhov tod tes, nws ua raws li cov khoom tiv thaiv fuse thiab siv thaum muaj npe overcurrent.
Disconnect switches thiab test keyboards:Lawv ua haujlwm rau lub cev txiav tawm hluav taws xob hluav taws xob, yog li lawv feem ntau ua haujlwm yam tsis tau them nqi. Cov keyboards no ua haujlwm mechanically thiab manually.
xob laim ntes:Lawv muaj lub luag haujlwm khaws cia ionized rays kom deb. Thaum muaj qhov nce siab ntawm qhov loj me, xob laim ntes tsim hluav taws xob arc uas ua rau cov paug tawm tam sim no rau hauv av thiab tsis yog rau tib neeg lossis cov khoom siv thiab kev teeb tsa.
Cov cuab yeej transformers:Lawv yog cov apparatuses lub luag haujlwm rau ntsuas qhov hluav taws xob tam sim no. Muaj ob hom: tam sim no transformers (CT), hloov tus nqi tam sim no, thiab muaj peev xwm transformers (PT), hloov cov nqi hluav taws xob yam tsis tau suav cov nqi tam sim no. Ob qho tseem ceeb yog siv nyob rau hauv lub sij hawm tiag tiag rau kev ntsuas, tswj, thiab kev tiv thaiv cov cuab yeej uas yuav tsum tau tam sim no los yog voltage signals.
Junction Boxes:Lawv yog cov kev sib txuas terminals ib theem uas tso cai rau peb ua derivations thiab mus txog tej qhov chaw.
Condenser:Lawv tso cai rau peb txuag hluav taws xob uas tsim tawm hauv qhov hluav taws xob. Los ntawm ob lub conductors sib cais los ntawm cov khoom siv insulating, lub zog yog khaws cia ib ntus.
