Surge Protection Device Classifications
Mune imwe nyaya yapfuura, takataurira imwe yerudzi rwekudzivirirwa kwechigadziro, izvo, nerudzi kana boka. Nyora 1 / 2 / 3 ndiyo inowanzoshambadza SPD yechikwata kana muL standard kana IEC. Iwe unogona kudzokorora iyi chinyorwa kuburikidza nekubatanidza uku:
Uye munyaya ino, tichaenda kuzotaura zvakawanda pamusoro pezvimwe zvikamu zvisingatauri pachikamu chepamusoro.
AC SPD & DC / PV SPD
Zviripachena, AC SPD yakanyanya kuwanda kupfuura DC SPD sezvo isu tese tichigara munharaunda munogadzirwa zvigadzirwa zvemagetsi zvakanyanya neAC zvazvino kutenda kuna Thomas Edison. Zvichida ndosaka iyo IEC 61643-11 yakajairwa inoshanda chete kune AC yekudzivirira yekudzivirira mudziyo kwenguva yakareba kwenguva yakareba hapana inoshanda IEC muyero weDC yekudzivirira inodzivirira mudziyo. DC SPD inova inozivikanwa sekukwira kwemaindasitiri emagetsi ezuva uye vanhu vanoona kuti kumisikidzwa kwePV kunowanzoitika kune mheni sezvo ichiwanzo kuwanikwa munzvimbo yakavhurika kana padenga reimba. Saka kudiwa kwekuwedzera kwekuchengetedza michina yePV kunyorera kuri kukura nekukurumidza mukati memakore gumi apfuura. PV chikamu ndicho chinowanzojairwa uye chakakurumbira kunyorera kweDC SPD.
Kuchengetedza kwekuchengetedza nyanzvi uye sangano vanoona kuti iyo inowana IEC 61643-11 haisi chiyero chakakwana chePV SPD sezvo ichingoshanda mune yakaderera magetsi simba system pasi pe1000V. Asi PV system's voltage inogona kusvika ku1500V. Naizvozvo, chiyero chitsva chinonzi EN 50539-11 chakatangwa kugadzirisa dambudziko iri. IEC yakaita zvakare kune aya mamiriro uye ndokutanga IEC 61643-31 yekushandisa kwePV SPD muna 2018.
IEC 61643-11: 2011
Yakadzika-magetsi ekuwedzera ekuchengetedza michina - Chikamu chegumi nemaviri: Midziyo yekudzivirira inodzivirirwa kune yakaderera-magetsi magetsi masisitimu - Zvinodiwa uye bvunzo nzira
IEC 61643-11: 2011 inoshandiswa kumagadzirirwo ekudzivirirwa kwepamusana pekudzivirira kusinganzwisisiki uye zvakakonzera zvinokonzerwa nemheni kana kuti kumwe kudengenyeka kwenguva pfupi. Izvi zvinogadziriswa kuti zvibatanidzwe kune 50 / 60 Hz magetsi emagetsi, uye midziyo yakarongerwa kusvika ku 1 000 V rms Maitiro ekugadzirisa, maitiro akaenzana ekuongororwa uye kuongororwa anosimbiswa. Izvi zvinosanganisira chikamu chimwe chete chisingasviki uye chinotarisirwa kugadzirisa kukwira kwemhepo uye kushandura mafungu emvura.
IEC 61643-31: 2018
Yakadzika-magetsi ekuwedzera ekuchengetedza michina - Chikamu 31: Zvinodikanwa uye nzira dzekuyedza dzeSPDs yekuisa photovoltaic
IEC 61643-31: 2018 inoshanda kuSurge Protective Devices (SPDs), inoitirwa kuchengetedzwa kwekuzvidzivirira kubva pamhedzisiro isina kunanga uye yakanangana nemheni kana zvimwe zvinopfuura zvenguva pfupi. Aya majaira akagadzirwa kuti abatanidzwe kune iyo DC divi ye photovoltaic yekumisikidza yakatarwa kusvika 1 500 V DC. Izvi zvishandiso zvine chimwe chete chisina-mutsetse chinhu uye zvinoitirwa kudzikisira mafungu ekuwedzera uye kutsausa mafungu ekuwedzera. Maitiro ekuita, chengetedzo zvinodiwa, zvakajairika nzira dzekuyedza uye ratings zvakasimbiswa. MaSPD anoenderana neichi chiyero akatsaurwa chete kuti aiswe padivi reDC ye photovoltaic jenareta uye iyo DC divi revashanduri. SPDs yePV masisitimu ane simba rekuchengetedza (semuenzaniso mabhatiri, capacitor mabhangi) haana kuvharwa. MaSPD ane akapatsanurwa ekuisa uye ekuburitsa zviteshi zvine iwo akanangana akateedzana impedance pakati peaya ma (terminal) (s) (anonzi maviri-chiteshi SPDs maererano neIEC 61643-11: 2011) haana kuvharwa MaSPD anoenderana neichi chiyero akagadzirirwa kuti abatanidzwe zvachose uko kubatana uye kubviswa kweakagadziriswa maPSD anogona kungoitwa uchishandisa chishandiso. Iyi muyero haishande kune anotakurika maPSD.
Izvi zvinoshandiswa muIEC yero. MuLL standard, yakakurumbira UL 1449 4th edition yakabudisa zviri mukati pePV SPD iyo yakanga isipo muhari ye3rd. Saka pakupedzisira, masangano ese akaenzana akatanga mitemo yeDVD / PV surge protection device.
Ngatitarisei nezveProsurge's PV SPDs.
Kuti uwane mamwe mashoko pamusoro DC / PV surge protection device, tapota shanyira peji ino:
Surge Protection Classification by Applications
Nenzira, zvigadziro zvekudzivirirwa zvinogona kuenzanisirwa nezvikwata se:
- SPD yekupa simba
- SPD yeChiratidzo
- SPD yeVhidhiyo
- SPD ye Network
- ect
Pano tinogona kuona mimwe mifananidzo yeSPD mune zvakasarudzwa.

Kazhinji, kunze kwechimiro che3 SPDs icho chinowanzotaura nezvemasimba emagetsi uye zvigadziro uye kugamuchira mutezo weplagi. Pane zvikwata zviviri zvinowanzoonekwa: DIN-rail mounting uye panopinda gorosi. Heano mifananidzo yeDIN-rail mounting SPD nePelel mounting SPD.
Tinogona kuona zvakajeka kuti vane ruzivo rwakasiyana.

Muchikamu chino, tinokurudzira hurukuro yedu pamusoro pechikoro chechigadziro chekudzivirira. Isu tinotaura pamusoro pekutsanangurira neAAC / DC, nekushanda uye nekuiswa. Zvechokwadi, kune dzimwe mimwe mitemo yekutarisa uye inonyatsotenderwa. Tinovimba kuti chinyorwa ichi chinogona kukubatsira iwe kuti unzwisise chidimbu chekuchengetedza chikwata chiri nani.
