I-Inverter yi-converter eguqula i-current ngqo (ibhetri, ibhetri yokugcina) kwi-alternating current kunye nesigxina kunye ne-voltage okanye i-frequency frequency kunye ne-voltage (ngokubanzi i-220V, i-50Hz sine wave). Ukuba i-inverter iza kuthengiswa kwimarike okanye ithunyelwe kumazwe angaphandle, kufuneka ivavanywe i-EMC ukuthobela imigaqo yokusingqongileyo yendawo. Uvavanyo lwe-EMC lukwaziwa njengokuhambelana kwe-electromagnetic (EMC), ebhekisa kuvavanyo olubanzi lobungakanani bokuphazamiseka kwentsimi yombane (EMI) kunye nokukwazi ukumelana nokuphazamiseka (EMS) kweemveliso zombane. Injongo yovavanyo lwe-EMC kukubona impembelelo yemitha yombane eveliswa ziimveliso zombane emzimbeni womntu, igridi yamandla kwindawo yoluntu kunye nezinye iimveliso zombane ekusebenzeni okuqhelekileyo.
1.Imeko yovavanyo: lwenziwa kwigumbi elikhuselekileyo okanye kwigumbi le-anic ukunciphisa ukuphazamiseka kwangaphandle.
2.Uvavanyo lwe-emission oluqhutywayo (I-Emission Eqhutywayo) Injongo yovavanyo: ukulinganisa uphazamiseko lwe-electromagnetic oluqhube i-inverter ngentambo yamandla okanye intambo yesiginali.
3.Uvavanyo lokukhutshwa kwemitha (Radiated Emission)* Injongo yovavanyo: ukulinganisa i-electromagnetic esasazwa sisiguquli esithubeni. Isibhengezo Emva kokuba le LOGO iyilwe, ndiye ndaqonda ukuba iphantsi uyilo lwe-LOGO yangaphambili! ×
I-4.Uvavanyo lwe-immunity yokuqhuba (I-Immunity eqhutywe) Injongo yokuvavanya: ukuvavanya ukhuseleko lwe-inverter ekuphazamisekeni olwenziwa ngomgca wesignali yombane.
5.Uvavanyo lokugonyeka kwemitha (Radiated Immunity) Injongo yovavanyo: ukuvavanya ukhuseleko lwe-inverter kuphazamiso lwemitha yendawo
I-6.Uvavanyo lwe-Electrostatic discharge (ESD) Injongo yokuvavanya: ukuvavanya ukukhuseleka kwe-inverter kwi-electrostatic discharge.
7.Uvavanyo lweqela lombane olukhawulezayo olukhawulezayo (EFT/Burst) Injongo yovavanyo: ukuvavanya ukhuseleko lwe-inverter kumaqela ombane okhawulezayo odlulayo.
8.Uvavanyo lweSurge (Surge) Injongo yovavanyo: ukuvavanya ukhuseleko lwe-inverter kwi-voltage yokunyuka.
9.Uvavanyo lokuphazamiseka kwe-Voltage sag (i-Voltage Dips kunye nokuphazamiseka)** Injongo yovavanyo: ukuvavanya ukhuseleko lwe-inverter kwi-voltage sag kunye nokuphazamiseka.
10.Ingxelo yovavanyo Rekhoda yonke idatha yovavanyo, kubandakanywa iimeko zovavanyo, iziphumo zovavanyo, njl., Hlalutya iziphumo zovavanyo, ugwebe ukuba i-inverter ihlangabezana nemigangatho ye-EMC efanelekileyo, bhala ingxelo yovavanyo, kuquka indlela yokuvavanya, iziphumo zovavanyo, izigqibo, njl.
11.Isiqinisekiso kunye nokumakishwa kweSiqinisekiso: emva kokuphumelela uvavanyo, faka isicelo sesatifikethi se-EMC kwiqumrhu loqinisekiso. Ukumakisha: emva kokufumana isatifikethi, ukumakishwa kwesatifikethi se-EMC esihambelanayo kunokwenziwa imveliso.
Oku ngasentla yinkqubo esisiseko yovavanyo lwe-EMC yee-inverters, kwaye amanyathelo athile anokulungiswa ngenxa yemigangatho eyahlukeneyo kunye neemfuno zokuvavanya. uneminye imibuzo malunga novavanyo lwe-EMC, nceda uqhagamshelane neengcali ze-Shifu Inspection and Testing Technology Service Co., Ltd. ukuze ufumane iimpendulo. Oku ngasentla (kubandakanya imifanekiso kunye neevidiyo) kufakwe kwaye kupapashwe "iNombolo yoThutho oluKhawuleza" umsebenzisi weqonga lomdali.
