Kev piav qhia ntxaws txog cov haujlwm tseem ceeb thiab ua tiav kev tiv thaiv ntawm Photovoltaic Inverters

Photovoltaic inverters yog cov khoom siv tseem ceeb ntawm cov tshuab hluav taws xob photovoltaic, ua cov haujlwm tseem ceeb ntawm kev hloov hluav taws xob, kev tswj tsis tau, thiab kev ua haujlwm ntse thiab kev saib xyuas. Lawv yog cov cuab yeej tseem ceeb los xyuas kom meej lub zog tsim hluav taws xob ruaj khov thiab ua raws kab sib txuas ntawm photovoltaic fais fab nroj tsuag. DC lub zog tsim los ntawm photovoltaic modules tsis tuaj yeem hloov kho ncaj qha rau cov qauv hauv tsev, kev lag luam, thiab kab sib kis. Nws yuav tsum tau hloov los ntawm AC rau DC los ntawm inverter. Kev tswj hwm ntawm cov khoom siv tag nrho tso siab rau Movable Contact for Photovoltaic PV Inverter Relay, uas tuaj yeem hloov kho kom haum rau lub inverter qhov pib- nce thiab kaw cov xwm txheej, ua kom ruaj khov ntawm kev sib txuas ntawm lub zog hloov pauv thiab ua tiav kev txhim kho lub zog siv hluav taws xob thiab kev ua haujlwm ruaj khov ntawm photovoltaic system.

Lub zog hloov dua siab tshiab yog qhov yooj yim tshaj plaws thiab cov haujlwm tseem ceeb ntawm photovoltaic (PV) inverter. PV panels nqus lub hnub ci zog thiab tsis tu ncua tso tawm ncaj qha tam sim no (DC), thaum feem ntau cov khoom siv hluav taws xob thiab cov phiaj xwm hluav taws xob pej xeem siv alternating tam sim no (AC). Lub inverter zoo converts DC rau AC. Sab hauv, cov cuab yeej suav nrog Flat Silver Contacts rau PV Power Relay, uas, nrog nws cov conductivity zoo heev thiab arc tsis kam, txo qhov kev poob thaum lub zog hloov pauv, txhim kho inverter efficiency, thiab tso cai rau PV fais fab mov ncaj qha siv rau kev thauj khoom hluav taws xob lossis txuas rau pej xeem daim phiaj, ua tiav kev siv lub hnub ci zog.

Ntxiv nrog rau qhov yooj yim inverter ua haujlwm, PV inverters muaj qhov tseeb voltage thiab zaus tswj kev muaj peev xwm, hloov mus rau cov qauv hluav taws xob sib txawv hauv ntau qhov xwm txheej. Cov kab hluav taws xob sib txawv hauv cheeb tsam muaj qhov sib txawv ntawm 50Hz thiab 60Hz, thiab ntau yam khoom siv hluav taws xob muaj qhov sib txawv voltage amplitude. Lub inverter yuav ntse calibrate nws cov zis tsis. Cov cuab yeej siv hluav taws xob tau nruab nrog Lub Xeev Tiv tauj Rivets rau PV AC Circuit Court Relay, txhim khu kev ruaj ntseg ntawm AC Circuit Court kev sib txuas, kom tsis txhob muaj hluav taws xob tsis zoo los ntawm qhov hluav taws xob thiab zaus hloov pauv, thiab xyuas kom meej tias cov khoom siv hluav taws xob ib txwm ua raws li cov phiaj xwm hluav taws xob hauv zos thiab cov khoom siv ua haujlwm.

Niaj hnub nimno photovoltaic inverters koom ua ke cov kev soj ntsuam ntse kom ua tiav cov haujlwm digital thiab kev tswj xyuas kev tswj hwm ntawm photovoltaic fais fab nroj tsuag. Cov khoom siv tuaj yeem sau cov ntaub ntawv tseem ceeb xws li kev khiav hauj lwm tam sim no, cov zis hluav taws xob, lub zog tsim hluav taws xob, thiab cov khoom siv kub hauv lub sijhawm, xa cov ntaub ntawv no mus rau cov khoom siv davhlau ya nyob twg ntawm huab cua kom yooj yim saib xyuas cov chaw taws teeb thiab teeb meem los ntawm cov neeg ua haujlwm tu. Txhawm rau hloov mus rau ntev - lub sij hawm ntse saib xyuas cov xwm txheej, cov cuab yeej tau nruab nrog Oxidized Hluav Taws Xob Sib Txuas rau Hnub Ci Relay, uas muaj kev tiv thaiv oxidation zoo heev thiab tuaj yeem tswj xyuas qhov kev sib cuag txuas mus ntev, kom ntseeg tau qhov txuas ntxiv thiab raug ntawm cov ntaub ntawv tau txais thiab cov teeb liab kis tau tus mob.

Kev tiv thaiv kev ua haujlwm zoo yog lub hauv paus lav rau kev ua haujlwm nyab xeeb ntawm photovoltaic inverters, kom tsis txhob muaj cov khoom puas tsuaj thiab kev nyab xeeb los ntawm ntau yam txhaum. Overvoltage thiab overcurrent tiv thaiv yog cov yam ntxwv tiv thaiv yooj yim; thaum lub input lossis output voltage los yog tam sim no tshaj qhov ntsuas qhov pib, lub inverter yuav sai sai ua rau tam sim no limiting thiab fais fab - tawm kev ua. Nws cov kev tswj xyuas sab hauv siv hluav taws xob tiv tauj rau Hnub Ci Hloov, uas muaj cov lus teb ceev ceev thiab siab rhiab heev, muaj peev xwm txiav tawm cov kab hluav taws xob txawv txav hauv milliseconds, tiv thaiv kev kub ntxhov thiab overcurrent los ntawm kev puas tsuaj rau cov khoom siv hluav taws xob thiab tiv thaiv tag nrho cov khoom siv photovoltaic.

Kev tiv thaiv kub yog ib qho tseem ceeb tiv thaiv mechanism rau kev ua haujlwm tsis tu ncua inverter. Ntev - lub sij hawm siab - load lag luam ntawm lub inverter ua kom muaj cua sov ntau, thiab siab - qhov kub thiab txias ib puag ncig tuaj yeem ua rau cov khoom qub, kev ua haujlwm tsis zoo, lossis txawm tias kub hnyiab. Cov cuab yeej muaj ib qho ua tau - nyob rau hauv qhov kub tswj module uas cia li txo hwj chim los yog kaw rau cua sov dissipation thaum kub tshaj qhov txwv. Cov tub ntxhais kub tswj kev hloov, ua ke nrog Bimetal Contacts rau PhotoVoltaic PV Electromagnetic Relay, tso siab rau qhov ntsuas kub ntawm cov yam ntxwv ntawm bimetallic sawb kom raug raws li qhov ntsuas kub tiv thaiv ua rau muaj kev ruaj ntseg ntawm cov khoom siv nyob rau hauv ob qho tib si kub thiab tsis kub.

Luv luv- tiv thaiv kev tiv thaiv kev ua txhaum hauv av tuaj yeem daws cov kab tsis ncaj ncees tam sim ntawd thiab tiv thaiv kev nyab xeeb loj. Thaum ib tug luv luv Circuit Court tshwm sim ntawm lub inverter tso zis los yog ib tug txhaum hauv av tshwm sim nyob rau hauv cov kab, cov khoom yuav instantly disconnect lub input Circuit Court thiab thaiv qhov kis ntawm txhaum tam sim no. AC sab tiv thaiv yog nruab nrog Static Silver Contact AC Sab Photovoltaic PV Relay. Cov nyiaj tiv tauj yog cuam tshuam -tiv taus thiab ablation- tiv taus, thiab tuaj yeem tiv taus qhov hluav taws xob loj tam sim no thaum lub caij luv luv, ua kom tiav qhov kev sib txuas sai sai thiab zam kom tsis txhob muaj kev nyab xeeb xws li cov khoom siv hluav taws xob thiab kab hluav taws xob.

Lub photovoltaic inverter kuj tau nruab nrog kev tshaj lij kev tiv thaiv xob laim, ua kom haum rau kev ua haujlwm nyuaj ntawm cov chaw nres tsheb photovoltaic sab nraum zoov. Cov khoom siv photovoltaic sab nraum zoov muaj kev cuam tshuam rau xob laim thiab surge voltage cuam tshuam. Lub inverter siv ua- nyob rau hauv cov tiv thaiv overvoltage, tso cov raj, thiab lwm yam khoom siv kom txo tau qhov siab tam sim ntawd -voltage surges. Lub zog cia thiab tso tawm hluav taws xob ntawm cov khoom siv tau txais lub tiaj tus Bimetallic Rivet rau DC Circuit Court Photovoltaic Relay, uas sib npaug ntawm kev ruaj ntseg thiab qhov hluav taws xob tiv taus muaj peev xwm, thiab tuaj yeem tiv taus qhov hluav taws xob tam sim ntawd tshwm sim los ntawm xob laim tawm tsam, kev tiv thaiv kev nyab xeeb ntawm lub inverter thiab tag nrho photovoltaic system.
