SPDs dzinogona kudzivirira kubva kumarudzi ese ekukanganiswa kwemagetsi here?
MaSPD akagadzirwa kuti adzivirire kubva pakukwira kwesimba kwenguva pfupi, asi ane miganhu zvichienderana nechiyero chawo. Anogona kusadzivirira zvizere kubva pakukwira kwesimba rakawanda kana kurohwa nemheni zvakananga kana mudziyo usina kuyera zvakakodzera. Kuti udzivirirwe zvakakwana, musanganiswa wemhando dzakasiyana dzeSPD unogona kushandiswa.
Musiyano uripo pakati peRudzi 1, Rudzi 2 rweChishandiso chekudzivirira SPD
Rudzi 1 SPD Yakagadzirirwa kubata kukwira kwemagetsi kwenguva pfupi kunokonzerwa nesimba guru, kazhinji kunokonzerwa nekurova kwemheni zvakananga. Midziyo iyi inowanzoiswa pamusuwo mukuru wemagetsi echivako, ichipa dziviriro huru kubva mumamiriro ezvinhu akaipisisa akadaro. Mhando 1 SPDs inokwanisa kubata mafungu emhepo anosvika 100 kA kana kupfuura, ichishandisa zvikamu zvekudzivirira zvine simba guru zvakaita sezvibatiso zvemhepo kuti ive nechokwadi chekuti sisitimu yakachengetedzwa panguva yekukwira kwakanyanya.
Rudzi rwechipiri SPD inopa dziviriro kuzvikamu zvekugovera zvemagetsi, ichigadzirisa mafungu akasara angave achiripo mushure mekudzivirirwa kweType 1. Dzakaiswa pamapaneru ekugovera kana ma sub-panels, ma Type 2 SPD akagadzirirwa kudzora mafungu akaderera, kazhinji kusvika ku20-40 kA pachikamu chimwe nechimwe. Midziyo iyi inosanganisira zvikamu zvakaita seMetal Oxide Varistors (MOVs) kana Gas Discharge Tubes (GDTs) kuti dzipe dziviriro yakakwana kumidziyo mushure mekudzivirirwa kwekutanga kwemasupu.
T1+T2 SPD Inosanganisa mabhenefiti emhando ye1 ne2 SPDs, ichipa dziviriro yakakwana kune sisitimu yese yemagetsi. Nekuisa Type 1 SPD pamusuwo mukuru wemagetsi kuti igadzirise mafungu ane simba rakawanda uye Type 2 SPD mukati mesystem yekugovera dziviriro yechipiri, T1+T2 SPDs inovimbisa dziviriro yakasimba kubva pakuwanda kwemafungu. Maitiro aya akabatanidzwa akanakira nzvimbo dzine njodzi dzakadai senzvimbo dzedata, zvipatara, nenzvimbo dzemaindasitiri, uko dziviriro yakakwana yemafungu yakakosha.
Kana zvichidikanwa michina yakawanda yekudzivirira surge (SPDs) kuchengetedza kuiswa, zvakakosha kuti ishande pamwe chete zvakanaka. Kana maSPD achibva kuvagadziri vakasiyana, zvakakosha kutarisa kuti anowirirana here. Mugadziri nevagadziri vemidziyo iyi ndivo vanonyanya kupa mazano ekuona kuti maSPD achaita basa nemazvo pamwe chete.
Chii chinonzi Surge Protective Device (SPDs)?
Mudziyo wekudzivirira kukwira kwesimba (SPD), unozivikanwawo semudziviriri wekukwira kwesimba, wakagadzirirwa kudzivirira michina yemagetsi kubva pakukwira kwesimba uye kukwira kwesimba kwesimba kwenguva pfupi. Unoshanda sechinhu chakakosha muhurongwa hwekudzivirira kuisa magetsi. SPD yakabatana pamwe chete nedunhu remagetsi remitoro yainodzivirira, zvinoreva kuti inogona kushandiswa pamatanho akasiyana-siyana enetwork yemagetsi. Kana yakabatana pamwe chete, SPD inoratidza kupindira kwakanyanya mumamiriro ezvinhu akajairwa. Zvisinei, kana kupindira kwesimba kwenguva pfupi kukaitika, kupindira kweSPD kunoderera, zvichiita kuti kupindira kwesimba remagetsi kuendeswe kuburikidza nemudziyo uye kure nemidziyo inonzwisisika. Maitiro aya anobatsira kudzivirira kukuvara kwemagetsi anokosha nekuona kuti simba rekuwedzera simba rakachengetedzwa zvakachengeteka.
