Inopenya pamusoro pemagetsi pamberi penzvimbo yekumberi (dV / dt = 1kV / us); iyo yekumusoro inokonzeresa pamusoro pemagetsi inowedzera pamwe nekuwedzera dV / dt.

Insulation Nemishonga uye Capacitance

Hunhu uhwu hunoita kuti gasi rinoburitsa chubhu isingaonekwe panguva yakajairika yekushanda mamiriro. Iyo yekudzivirira kupokana yakanyanya kwazvo (> 10 Gohm) nepo iyo capacitance iri yakaderera kwazvo (<1 pF).

ZVINOTAURWA

Maitiro Ekuyedza uye kurudziro yekumisikidza yekutaurirana mutsetse vadziviriri vanofanirwa kutevedzera anotevera matanho:

• UL497B: Dziviriro yeData Kutaurirana uye Moto-Alarm Maseketi

kugadzwa

Kuti ubudirire, dziviriro yekuwedzera inofanirwa kuiswa maererano nemisimboti inotevera.

• Nzvimbo yepasi yemudziviriri wedutu uye yemidziyo yakachengetedzwa inofanira kusungwa.
• Kudzivirirwa kunoiswa pamusuwo webasa rekumisikidza kuti uchinjise mafambiro emhepo nekukurumidza sezvazvinogona.
• Mudziviriri wekudzivirira anofanirwa kuiswa padhuze padhuze, asingasviki 90 tsoka kana 30 metres) kumidziyo yakachengetedzwa. Kana mutemo uyu usingakwanise kuteverwa, vechipiri vadziviriri vanodzivirira vanofanirwa kuiswa padyo nemidziyo
• Iyo conductor yekumisikidza (pakati pepasi kuburitsa kwemudziviriri uye iyo yekumisikidza bonding dunhu) inofanirwa kuve ipfupi sezvinobvira (isingasvike 1.5 tsoka kana 0.50 metres) uye iine nzvimbo yemuchinjikwa-inosvika angangoita 2.5 mm akaenzana.
• Kuramba kwepasi kunofanirwa kutevedzera kune yemunharaunda kodhi yemagetsi. Hapana pasi rakakosha rinodiwa.
• Tambo dzakadzivirirwa uye dzisina kudzivirirwa dzinofanira kuchengetwa dzakaparadzaniswa kusvika kudzora kubatanidza.

KUSVIRA

LSP gasi inoburitsa machubhu haidi kuchengetedzwa kana kutsiviwa pasi pechinyakare mamiriro. Izvo zvakagadzirirwa kumira zvinodzokororwa, zvinorema-basa rekuwedzera masaisai pasina kukuvara.
Zvakangodaro, zvine hungwaru kuronga zvemamiriro ezvinhu akaipisisa uye, nekuda kwechikonzero ichi; LSP yakagadzirira kutsiva kwezvinhu zvekudzivirira pazvinoshanda. Iyo chinzvimbo cheyako dhata mutsara yekukwira dziviriro inogona kuyedzwa neLSP's modhi SPT1003. Chidimbu ichi chakagadzirirwa kuyedza iyo DC inopenya pamusoro pemagetsi, kudzikamisa ma voltages uye kuenderera kwemutsara (sarudzo) yemudziviriri wedutu. Iyo SPT1003 ndeye compact, pushira bhatani unit ine digital kuratidza. Iyo voltage renji yemuedzo ndeye 0 kusvika 999 volts. Inogona kuyedza yega zvikamu zvakaita seGDT's, diode, MOVs kana zvimire-zvega zvishandiso zvakagadzirirwa AC kana DC zvinoshandiswa.

NZIRA DZAKANAKA: MISANGANO YOKUDZIVIRIRA MHENJO

Kana chimiro chinofanira kuchengetedzwa chakashongedzwa neLPS (Mheni Kudzivirirwa Sisitimu), vadziviriri vefoni, mitsara yedata kana AC magetsi mitsara akaisirwa pamusuwo webasa rezvivakwa anofanirwa kuyedzwa kune yakananga mheni inokanganisa 10 / 350us waveform iine hushoma hwekuwedzera kuitika kwe2.5kA (D1 chikamu bvunzo IEC-61643-21).
