Qhov kev pab lub neej ntawm ntau cov khoom siv hauv tsev tsis nyob ntawm lub hom ntawm cov khoom yuav khoom, tab sis nyob ntawm qhov zoo ntawm qhov hluav taws xob xa mus rau lub network. Tom qab tag nrho, kev kaw lossis surges hauv qhov hluav taws xob tuaj yeem ua kev puas tsuaj rau cov cuab yeej. Yog li ntawd, nws yog qhov tseem ceeb kom paub tias koj yuav tiv thaiv lawv li cas ntawm kev them nqi voltage.
Cov Lus Qhia
Kauj ruam 1
Cov chav hluav taws xob (voltage B) txwv. Feem ntau lawv tau teeb tsa hauv cov tsev ntiav. Cov neeg ntes no yog kev tiv thaiv ntawm xob laim thiab ntau yam kev nkag siab, suav nrog cov cua hauv cov cua. Cov kev txwv teeb meem tau muab tso rau ntawm lub qhov rooj nkag mus rau hauv lub tsev, uas yog, nyob hauv qhov chaw hloov lub ntsiab. Chav kawm lim hle B muaj peev xwm tiv thaiv qhov khoom los ntawm kev tso tawm tam sim no mus txog 70 kA. Lub lim piam yog raws raws li varistors. Txij li cov varistors tau nce nonlinearity, lub ntsiab tam sim no dhau los ntawm kev ntes, yog li txo qib overvoltage.

Cov kab hluav taws xob tsis pub tshaj ntawm cov chav kawm C. Lawv tiv thaiv cov cuab yeej los ntawm cov hluav taws xob uas tau dhau ntawm cov chav kawm B, lossis lawv yog thawj qhov tiv thaiv hauv cov vaj tse uas cov chav kawm tsis pub tshaj B. Nws tiv thaiv cov hlua hluav taws xob sab hauv, tawm hluav taws xob, hloov chaw, thiab lwm yam. Nws yog qhov tseem ceeb heev rau nruab qhov voltage voltage txwv ntawm qhov deb ntawm tsawg kawg 7 meters los ntawm txhua lwm yam, vim qhov no yuav xyuas kom lawv cov kev hloov pauv tau.
Kauj ruam 3
Chav kawm B + C qhov hluav taws xob tsis pub tshaj. Hom kev sib xyaw ua ke no tso cai rau koj kom txuag tau qhov chaw hauv cov thaiv, vim tias tag nrho cov cuab yeej tau tsim nyob rau hauv ib lub thawv sib txawv, thiab qhov loj me tuaj yeem sib txawv nyob ntawm seb koj xav tau ntau npaum li cas los tiv thaiv cov neeg xyuas pib.
Kauj ruam 4
Qib D voltage lim txwv. Tej hom lim dej no yog siv los tiv thaiv cov khoom siv uas kim tshaj plaws, yog li nws tau nruab ncaj qha nyob ib sab ntawm lawv thiab tsuas yog tiv thaiv lawv nkaus xwb. Tus neeg ntes no tsuas siv tau nrog lwm qib kev tiv thaiv, txwv tsis pub ib qho cuam tshuam yuav ua rau nws puas lawm.
Kauj ruam 5
Voltage relay. Thaum qhov hluav taws xob hauv lub network hloov pauv, qhov hloov mus hloov tawm txhua yam khoom siv, thiab thaum lub xov tooj hluav taws xob nyob, nws txuas nrog lawv. Cov ntawv xa tawm yog siv los tiv thaiv TV, tub yees, tshuab ntxhua khaub ncaws, thiab lwm yam.
Kauj Ruam 6
Surge Tiv Thaiv. Tus ntsuas hluav taws xob tswj qhov hluav taws xob poob. Yog tias qhov hluav taws xob mus dhau qhov txwv tsis pub tshaj, ces cov neeg siv khoom lag luam raug txiav tawm ntawm kev sib txuas. Tom qab qhov hluav taws xob hloov pauv, qhov stabilizer tig mus.
Kauj Ruam 7
Cov khoom siv fais fab uas tsis tuaj yeem cuam tshuam tau. Fais fab tuag feem ntau yog ib qho txaus ntshai rau cov khoos phis tawj. Yog tias muaj qhov hluav taws xob tas li ntawm hluav taws xob, tom qab ntawd cov cuab yeej yuav hlawv tag. Txhawm rau kom tsis txhob muaj qhov no, nws zoo dua los nruab ib lub hwj chim tsis cuam tshuam, uas yuav tso cai, thaum muaj hluav taws xob ceev, txhawm rau kaw lub khoos phis tawm kom raug thiab khaws txhua yam ntaub ntawv.
