Fais fab Inverter Circuit Diagram

Vim yog kev qaug zog ntawm cov khoom siv hluav taws xob ib txwm muaj thiab tib neeg kev mloog rau ib puag ncig, lub zog hluav taws xob tau ntsib cov kev hloov pauv loj heev, thiab cov khoom siv hluav taws xob faib tawm yuav dhau los ua cov kev taw qhia kev txhim kho yav tom ntej ntawm lub zog hluav taws xob.

Nrog nws cov txiaj ntsig tshwj xeeb, kev tsim hluav taws xob photovoltaic tau lees paub tias yog ib qho ntawm cov thev naus laus zis siab tshaj plaws thiab muaj kev vam meej.

Qhov loj tshaj feature ntawm lub inverter siv nyob rau hauv lub hnub ci zog tiam system yog lub luag hauj lwm ntawm taug qab lub siab tshaj plaws zog point.

Kev tiv thaiv Inverter feem ntau suav nrog:

1) Instantaneous overcurrent tiv thaiv. Thaum cov tam sim no ntws los ntawm lub inverter ntaus ntawv mus txog qhov txawv txav (dhau tus nqi tso cai) vim yog luv luv Circuit Court ntawm lub load sab ntawm lub inverter, thiab lwm yam, lub inverter yuav tsum nres instantaneously txiav tawm tam sim no. Hloov

Thaum cov zis tam sim no nce mus txog qhov txawv txav, kev ua haujlwm ntawm inverter tseem raug tso tseg.

2) Kev tiv thaiv overload. Cov zis tam sim no ntawm inverter tshaj qhov ntsuas tus nqi thiab txuas ntxiv mus rau ntau tshaj li lub sijhawm teev tseg. Txhawm rau tiv thaiv kev puas tsuaj rau lub inverter thaum lub sij hawm thiab lub voj voog, kev ua haujlwm yuav tsum tau nres. Kev tiv thaiv kom zoo yuav tsum muaj cov yam ntxwv sib txawv ntawm lub sijhawm, siv cov thermal relays lossis hluav taws xob thermal tiv thaiv (siv cov hluav taws xob hluav taws xob). Lub overload yog tshwm sim los ntawm loj heev GD (inertia) ntawm lub load los yog lub cev muaj zog yog thaiv vim lub overload.

3) Instantaneous fais fab tuag tiv thaiv. Rau qhov tsis ua haujlwm tam sim ntawd hauv ob peb milliseconds, cov tswj Circuit Court ua haujlwm ib txwm. Txawm li cas los xij, thaum lub sijhawm tsis ua haujlwm tam sim no ntau dua 10s, feem ntau nws yuav ua rau lub zog tswj kev ua haujlwm tsis zoo thiab lub hauv paus tseem ceeb tsis tuaj yeem muab lub zog, yog li lub inverter yuav tsum tsis ua haujlwm tom qab kuaj pom.
