Zvinhu zvina zvakakosha zvemudziyo unodzivirira kukwira kwemvura (SPD)

Chidziviriro chekudzivirira (SPD) chishandiso chemagetsi chinopa dziviriro yakachengeteka yemidziyo yakasiyana-siyana yemagetsi, zvishandiso, uye tambo dzekutaurirana. Kana magetsi kana magetsi akawedzera kamwe kamwe mumitsara yemagetsi kana tambo dzekutaurirana nekuda kwekukanganiswa kwekunze, chinodzivirira kukwira kwemhepo chinogona kukurumidza kutungamira nekutsausa kukwira kwemhepo kudzivirira kukuvara kwezvimwe zvishandiso mudunhu. Pane zvinhu zvina zvakakosha zvekufunga nezvazvo pakuongorora SPD:

1. Voltage yepamusoro inoshanda (Uc) Uc inoreva voltage yepamusoro yerms (RMS) kana DC inogona kushandiswa kuSPD protection mode. Chaizvoizvo, inomiririra voltage yakayerwa yeSPD. Kukosha kweUc kwakabatana nehupenyu hwebasa uye huwandu hwekudzivirira voltage yeSPD. Kunyangwe kusarudza kukosha kwepamusoro kweUc kuchigona kuwedzera hupenyu hwebasa hwechigadzirwa, kuchawedzerawo voltage yakasara, izvo zvinokanganisa chinhu chakachengetedzwa.

2. Nominal discharge current (In) In ndiyo peak current ye 8/20μs current wave inoyerera ne surge protector. SPD standard inotsanangura nhevedzano yeIn values. Pakugadzira uye kugadzira modhi chaiyo yeSPD kuti isvike padanho rakati, In value inoenderana inosarudzwa kubva muIn series kuti iongororwe. Bvunzo inobudirira inosarudza value yakasarudzwa seIn value yeSPD.

3. Kuwanda kwemagetsi anobuda muongororo yekirasi yechipiri (Imax) Imax inomiririra peak current ye8/20μs current wave inoyerera nepamuchina wekudzivirira mukuyedza kweClass II. Kunyangwe tsananguro yeparameter iyi yakafanana neinomira electron (In), chiyero cheSPD chinopa huwandu hwemaImax values ​​​​padivi peIn series, uye mukati medanho rimwe chete, Imax > In. Saka, SPD inopfuura bvunzo padanho reIn harivimbisi kuti SPD ine Imax level yakafanana ichapasawo bvunzo. Kunyangwe In neImax zviri zvese peak values ​​​​dze8/20μs current wave, peak value uye huwandu hwenguva iyo electron inobuda panguva yekuyedza zvakasiyana.

4. Kudzivirira kweVoltage (Kumusoro), inozivikanwawo se residual voltage, zvinoreva voltage iri muSPD kana magetsi ane waveform yakatarwa achipfuura nepakati peSPD mushure mekunge SPD yatanga. Iyi parameter yakakosha kuchengetedza voltage inomira yemidziyo yakachengetedzwa uye inofanira kunge yakaderera pane voltage inomira yemidziyo yakachengetedzwa.

Kunzwisisa nekuongorora maparamita aya kwakakosha pakushandisa michina yekudzivirira kukwira kwemvura. Kufunga zvakanaka uye kusarudzwa kwemaSPD zvichibva paparamita aya kuchaita kuti ape dziviriro inoshanda kumidziyo yemagetsi, zvishandiso uye tambo dzekutaurirana, zvichideredza kukuvara kunokonzerwa nekukwira kwemvura nekuputika kwemvura.
