Surge Protective Devices (SPDs) inopa dziviriro kubva pamagetsi emagetsi uye spikes, kusanganisira izvo zvinokonzerwa zvakananga uye zvisina kunanga nemheni. Inogona kushandiswa semidziyo yakakwana kana sezvikamu mukati memidziyo yemagetsi.
Photovoltaic (PV) system inoshandura simba rezuva kuita rakananga razvino magetsi. PV sisitimu inotangira kubva kudiki, padenga-yakaiswa kana chivakwa-yakabatanidzwa masisitimu ane masimba kubva kune mashoma kusvika makumi akati wandei emakilowatts, kune makuru ekushandisa-mwero magetsi emagetsi emazana emamegawati. Iyo inogona kuitika yezviitiko zvemheni inowedzera nePV system saizi. Kunzvimbo dzine mheni kazhinji, isina kudzivirirwa PV masisitimu anotambura akadzokororwa uye kukuvara kwakanyanya. Izvi zvinoguma nekugadzirisa kwakakura uye kutsiva mutengo, system downtime uye kurasikirwa kwemari. Yakanyatso kuisirwa surge protective device (SPDs) inoderedza kukanganiswa kwezviitiko zvemheni.
Sensitive magetsi emidziyo yePV system senge AC/DC Inverter, maturusi ekutarisa uye PV array anofanirwa kuchengetedzwa nesurge protective device (SPD).
Kuti uone iyo yakakodzera SPD module yePV system uye kuisirwa kwayo, iwe unofanirwa kuziva:
1.the mheni inotenderera inopenya density;
2.tembiricha yekushanda kwehurongwa;
3.the system's voltage;
4.the system's short circuit current rating;
5.the level of waveform iyo inofanirwa kuchengetedzwa
kurwisana (nemheni isina kunanga kana yakananga); uye nominal discharge current.
Iyo SPD iyo inopihwa pane dc inobuda inofanirwa kuve ne dc MCOV yakaenzana kana yakakura kupfuura yakanyanya photovoltaic system voltage yepanera.
THOR TRS3-C40 series type 2 kana Type 1+2 DC SPDs yePV solar system inogona kuita seUcpv DC500V,600V,800V,1000V,1200V, uye max 1500v.
