Cov ua ntawm lub hwj chim surges thiab yuav ua li cas los tiv thaiv los ntawm lawv

Tam sim no rau peb raws li tau txais kev pab ntawm hluav taws xob, ua ib tug lossis loj teeb meem surges nyob rau hauv lub network los yog mus tas li txo (nce) nws tus nqi. Ntshe qhov no yuav tsis ua hauj lwm ntawm lub tsev khoom siv uas yog tsim los rau ib tug deflection voltage yog tsis ntau tshaj li 20-30 B. Tsis tas li ntawd, tsis tsuas txaus ntshai high voltage thaum lub twj paj nruag yuav hlawv, tab sis kuj tsis tshua muaj. Piv txwv li muaj peev xwm tsis pib lub tub yees compressor

Ib tug ntawm lub ntsiab ua rau deviations los ntawm lub cev voltage theem qhov tseem ceeb, yog lub cev tsis muaj hwj huam sob mus rau tiv nrog niaj hnub nyuaj siab. Raws li lawv tau tsim thiab ua 20-30 xyoo dhau los, txij li thaum uas lub sij hawm, lub network load nce pua pua ntawm lub sij hawm. Nyob rau hauv tas li ntawd, cov kev hloov qhov xwm ntawm tus load, ib tug loj tus naj npawb ntawm pab kiag li lawm uas hloov Composes sinusoidal voltage.

Raws li ib tug tshwm sim, thaum ib txhij hloov ib tug loj pes tsawg tus neeg, muaj ib ntus undervoltage, e.g., thaum lub tuam txhab muaj xws li nws installation.

Nyob rau hauv lub caij ntuj no, thaum ua hauj lwm ib tug loj tus naj npawb ntawm tso cua sov, lub load rau ntawm cov network yog thiaj muaj siab hais tias cov voltage nqi yuav ua tau lossi me dua li ib txwm.

Cov tib tuas theem ua haujlwm uas tshwm sim raws li ib tug tshwm sim ntawm ib tug tsis load rau qhov sib txawv theem. Raws li ib tug tshwm sim, lub loaded theem voltage yog nws txo qis, thiab nyob rau underused - yuav tsub kom. Qhov teeb meem no yog aggravated loj tus naj npawb ntawm mem tes technology nyob rau hauv peb qhov, uas ntxiv tsub kom lub Unbalance ntawm theem.

Raws li ib tug nyias muaj nyias ib ua ntawm lub hwj chim surges yuav paub qhov txawv thaum muaj xwm ceev network hom. Piv txwv li, yog hais tias muaj yog ib tug so ntawm qhov nruab nrab neeg xyuas pib, tag nrho cov qhov hluav taws xob khoom siv nyob rau hauv lub tsev tej zaum yuav muaj ib tug voltage ntawm 380 V. Ib yam yuav tshwm sim yog hais tias tus electricians yuav tsis ua raws li cov zoo hu ntawm lub nruab nrab neeg xyuas pib rau ib qho chaw ntawm lub transformer windings. Lwm yog vim li cas tej zaum yuav ua tau ib tug xob strike, thiab tsis tsuas yog ncaj qha nyob rau hauv kev sib cuag nrog ib tug hwj chim kab, tab sis nyob ze lawv, yuav ua ib tug ntse voltage nco.

Ib txoj kev uas yuav tiv thaiv hwj chim surges yog rau nruab ib voltage relay. Qhov no ntaus ntawv tso cai rau koj mus tua hwj chim rau lub tsev network, thaum nws yog nyob sab nraum lub ntau yam tshaaj nyob rau hauv qhov chaw. Txuas voltage tshwm sim tsuas yog tom qab normalization ntawm kev nyuaj siab. Lub disadvantage ntawm no txoj kev yog ib tug tsis zoo ntxim rau cov nyuaj cut-off voltage hluav taws xob khoom siv.

Yog hais tias lub voltage nyob rau hauv koj lub tsev los yog chav tsev yog lossi txo los ntawm qhov chaw kawm lub voltage relay yog tsis pab. Qhov yooj yim txoj kev yog mus xyuas lub voltage rau lub nyob ib sab ob theem. Tej zaum koj yeej cia li hooked rau ib tug overloaded theem, thiab nyob ib lub sij hawm thaum koj muaj ib tug voltage ntawm 190 V, thiab cov neeg nyob ze yuav ua tau 250 V. Nyob rau hauv cov ntaub ntawv no nws yog txaus mus txuas rau lwm theem.

Yog hais tias lub voltage ntawm lub nyob sib ze theem xws li cov uas tsis muaj, feem ntau yuav tau tsim kom muaj ib tug voltage regulator. Qhov no ntaus ntawv tso cai kom muaj ib tug tsis tu ncua tso zis voltage hais txog ntawm lub qhov ntau ntawm cov khoom voltage. Muaj yog ib tug ntau ntau yam ntawm voltage regulators, lub ntsiab ntawm kev xaiv yog tus laij hwj chim xa mus rau lub network.

Nyob rau hauv txhua rooj plaub, yog hais tias tus voltage nyob rau hauv koj lub tsev uas tsis muaj los yog high school, voltage spikes tshwm sim, hu rau ib tug electrician. Nws yuav tshawb nrhiav qhov ua rau voltage hloov thiab kom muab tau lub ntsiab rau qhov teeb meem.
