Surge Dziviriro Dziviriro Dzinobata pasi pemamiriro matatu akanyorwa pazasi.

A. Zvakajairika mamiriro (kusavapo kwekuvhiya)

Panyaya isina mamiriro ekuvhiya, spd haina kukanganisa hurongwa uye zviitiko sedunhu rakavhurika, rinosara munzvimbo yakakwirira.

B. Munguva yekushambadzira voltage

Panyaya yeVoltage Spikes uye kuwanda, SPD inoenda kuConstruction State uye kutadza kwayo kwakaderera. Nenzira iyi, inochengetedza hurongwa nekutsausa kukurudzira kwazvino pasi.

C. Kudzokera kune yakajairika kushanda

Mushure mekunyanyisa kuwanda kwakadzingwa, spd yakashandurwa kumashure kune yakajairika yakakwirira yekukanganisa mamiriro.

Surge Dziviriro Zvishandiso (SPDS) zvakakosha zvikamu zvemagetsi network. Nekudaro, kusarudza smed yakakodzera yehurongwa hwako kungave kwakaoma nyaya.

Maximum anoenderera mberi anoshanda voltage (UC)

Iyo yakavezwa voltage yeSPD inofanira kuenderana neyemagetsi system voltage yekupa zvakakodzera kudzivirirwa kuhurongwa. Iyo yakaderera voltage rating ichakuvadza mudziyo uye chiyero chepamusoro hachizotsauki zvishoma.

Mhinduro nguva

Inotsanangurwa senguva yeSpd inosangana nema nhandare. Iyo inokurumidza spd inopindura, iri nani dziviriro neye spd. Kazhinji, Zener Diode yakavakirwa SpD ine mhinduro inokurumidza. Mhando dzeGasi-dzakazara dzine nguva inononoka kupindura uye flus uye mov mhando dzine nguva inononoka kupindura nguva.

Zita rechiratidziri razvino (mu)

SPD inofanira kuedzwa pa8 / 20μs waveform uye yakajairika kukosha kweanogara miniature-sized spd is 20ka.

Maximum Impulse discharge yazvino (IIMP)

Chishandiso chinofanira kukwanisa kubata iyo yekuvhiya yazvino inotarisirwa pane yekuparadzira network kuti ive nechokwadi chekuti haina kukundikana panguva yechiitiko chechiitiko uye chishandiso chinofanira kuedzwa ne 10 / 350μ waveform.

Kupinza Voltage

Ichi chikumbaridzo voltage uye pamusoro peiyi voltage level, SPD inotanga kuunganidza chero voltage inoti iyo inoona mugetsi remagetsi.

Mugadziri uye Certification

Kusarudza SPD kubva kune inozivikanwa-inozivikanwa mugadziri iyo ine chitupa kubva kune isingasarwi kuongororwa, senge ul kana IEC, yakakosha. Iyo Certification inovimbisa kuti chigadzirwa chave chichiongororwa uye chinopfuura zvese kuita uye kuchengetedza zvinodiwa.

Kunzwisisa izvi zvakarongeka nhungamiro kuchaita kuti ukwanise kusarudza yakanakisa yekudzivirira mudziyo wezvaunoda uye vimbiso zvinobudirira kudzivirirwa.

Surge Dziviriro Zvishandiso (SPDS) inonzwisisika kuti ipe kuvimbika kuchengetedza pamwe chete neyakawandisa, asi zvimwe zvinhu zvinogona kutungamira mukutadza kwavo. Zvinotevera zvimwe zvezvikonzero zvepasi pekuseri kwemaseti kutadza:

1.Exesive Simba Kuwanda

Chimwe chezvikonzero zvikuru zvekutadza kweSpd kuri kuwedzera, kuwanda kunogona kuitika nekuda kwemheni kurova, zvinopesvedzera simba, kana mamwe magetsi anokanganisa. Ita shuwa yekuisa iyo chaiyo mhando ye spd mushure mekuverenga yakakodzera magadzirirwo zvichienderana nenzvimbo.

2.geing chinhu

Nekuda kwemamiriro ezvinhu epakatiripiti kusanganisira tembiricha uye humidity, spards ine hupenyu husina huwandu hwesherufu uye hunogona kudzikira nekufamba kwenguva. Uyezve, mapepa anogona kukuvadzwa neanogara voltage spikes.

3.configuration nyaya

Kusarongeka, sekuti kana iyo gadziriro-yakagadzirirwa spd yakabatanidzwa kune mutoro wakabatana kuburikidza ne delta. Izvi zvinogona kufumura SPD kune yakakura voltages, iyo inogona kukonzera kutadza kwepasi.
