Cov thev naus laus zis niaj hnub ua kom muaj peev xwm tswj tau thiab tiv thaiv cov cuab yeej hauv peb-theem tam sim no network. Qhov cuam tshuam loj tshaj plaws ntawm kev ua haujlwm ntawm cov khoom siv hluav taws xob tuaj yeem yog "theem imbalance", qhov tshwm sim no tshwm sim nws tus kheej hauv qhov tseeb tias qhov hluav taws xob ntawm tus nqi sib txawv ntws hauv txhua theem ntawm lub network. Qhov sib txawv voltage nyob rau hauv txhua theem ua rau overheating ntawm windings ntawm motors thiab transformers, yog li muab lawv tawm ntawm qhov kev txiav txim. Txhawm rau zam qhov tshwm sim, xws li cov khoom siv tswj hwm raws li theem tswj relay tau tsim. Cov cuab yeej no tso cai rau koj los tswj cov tee tseem ceeb thiab theem tsis ua haujlwm, nrog rau lawv qhov kev cuam tshuam.
phase tswj relay
Lub relay yog ib qho khoom siv hluav taws xob tsim los tswj qhov raug thiab zoo voltage mov rau lub network. Cov theem tswj relay nws tus kheej tsis feem ntau ua nws txoj haujlwm, feem ntau yog thaum hloov, lossis thaum muaj xwm txheej ceev hauv peb-theem voltage network. Yog tsis muaj xws li ib tug relay nyob rau hauv lub hwj chim circuits yuav ua rau kom lub sij hawm rau kev sib txuas thiab configuring khoom. Nws yog ib qho tsim nyog yuav tsum nco ntsoov tias qhov relay no tau nruab rau hauv lub network nkaus xwb nrog peb-theem voltage.
Destination
Phase tswj relays tau teeb tsa hauv cov khoom siv uas tau hloov pauv thiab hloov pauv ntau zaus, nrog rau qhov tseeb phasing tseem ceeb kom tsis txhob ua rau cov khoom puas.
Vim qhov tseeb tias tsis raug phasing hauv qee qhov kev teeb tsa tuaj yeem ua rau muaj kev ua haujlwm tsis zoo, qee hom compressors raug xa mus rau cov kev teeb tsa no. Yog tias cov theem txuas nrog tsis raug, lub sijhawm ua haujlwm ntev txog 5 vib nas this yog txaus rau lub compressor tsis ua haujlwm. Tsis tas li, yog tias lub hwj chim txuas tsis raug, pab pawg kho yuav siv sij hawm los tshawb nrhiav qhov laj thawj ntawm kev ua haujlwm tsis raug ntawm cov cuab yeej, uas tuaj yeem zam tau los ntawm kev tswj hwm theem hauv Circuit Court.
pros and cons
Cia peb xav txog qhov zoo thiab qhov tsis zoo siv piv txwv ntawm EL theem tswj relay. Qhov zoo ntawm xws li ib tug relay yog suav hais tias feem ntau pheej yig, nyob rau hauv sib piv rau txawv teb chaws analogues. Tsis tas li ntawd, kev siv xws li ib tug relay yog suav hais tias yog kev siv lub mains voltage ntawm lub installation nws tus kheej, qhov twg lub relay yog ntsia, raws li lub hwj chim mov. Cov analogues txawv teb chaws xav tau cov chaw sib cais rau lawv cov khoom siv hluav taws xob, uas cuam tshuam rau cov txheej txheem tswj.
Kev tswj cov theem hauv tsev yog tsim los ua haujlwm nyob rau hauv cov xwm txheej nyuaj, xws li subway thiab metallurgical tuam txhab. Hauv peb theemtes hauj lwm ntawm xws li kev lag luam thiab kev teeb tsa muaj kev cuam tshuam zoo, uas txawv teb chaws analogues tsis tuaj yeem tiv nrog lawv lub luag haujlwm. Kev khiav hauj lwm kub ntau ntawm domestic relays ncav cuag -45 ° C.
Qhov tsis zoo suav nrog kev tsim hluav taws xob ntau ntxiv thaum lub sijhawm ua haujlwm ntawm cov qauv hauv tsev. Nyob rau hauv circuits nrog analog EL teeb liab ua, theem saib xyuas relay feem ntau malfunctions. Tsis tas li ntawd, qhov tsis zoo ntawm cov qauv no suav nrog cov qauv tsim qauv, nrog rau qhov zoo ntawm cov khoom siv hauv kev tsim khoom.
Txoj Cai Ua Haujlwm
Xyaum hauv txhua qhov kev teeb tsa hluav taws xob muaj cov tshuab hluav taws xob thiab cov tshuab hluav taws xob, qhov zoo ntawm kev ua haujlwm ntawm kev teeb tsa nws tus kheej nyob ntawm qhov ua haujlwm kom raug. Txhawm rau zam qhov ua tsis tiav, lawv siv cov theem tswj relay. Lub relay nws tus kheej muaj ib lub voj voog uas xam cov theem kom raug kom tso tawm cov hluav taws xob tiv tauj.
Nws raug nquahu kom nruab lub relay hauv kev tswj hwm kev kub ntxhov, nrog rau qhov no suav nrog hauv hom xwm txheej ceev, tag nrho cov kev teeb tsa yuav raug tua tag nrho, tiv thaiv cov khoom siv tsis ua haujlwm. Lub relay nws tus kheej yog qhib kom txog li 3 vib nas this, tua lub tsev thaum muaj xwm txheej. Thaum lub sijhawm ua haujlwm ib txwm muaj, chav tsev kuj tseem hloov nrog lub sijhawm ncua ntev txog 10 vib nas this.
