4.5.1 Kutanga Kunonoka

Munguva yeCPS yekutanga-nguva, inongodzivirira kushayikwa kwefuse, kukundikana kwechikamu, overvoltage, undervoltage, undercurrent, short circuit, leakage uye matatu-phase unbalance.Kuti udzivise kuchengetedzwa kwepamusoro ikozvino uye overcurrent apo CPS inotanga;nguva yekumisikidza ndeye (Sarudza pakati pe1 ~ 99) masekonzi;

4.5.2 Overvoltage uye undervoltage dziviriro

Iyo chete yekubatsira magetsi voltage inodzivirirwa kuti ive nechokwadi chekushanda kwecoil.

Overvoltage dziviriro: Kana iyo yekuwedzera simba rekupa magetsi ichidarika kukosha kweseti (kumisikidza fekitori iri 120% Us), nguva yekuita ishoma pane kana kuenzana nemasekonzi gumi.

Undervoltage dziviriro: kana yekuwedzera magetsi emagetsi yakadzikira pane yakatarwa kukosha (factory kumisikidza 75% Us), nguva yekuita ishoma pane kana kuenzana negumi masekonzi.

4.5.3 Inverse-nguva-mutoro-refu-kunonoka kudzivirira

Mushandisi anoisa yakatarwa kushanda ikozvino le yehungwaru kusunungurwa maererano nemutoro wezvino I, kuitira kuti mutoro wazvino I uri pakati pe80 ne100% le, uye nguva yekuita inogadziriswa maererano nemaitiro emutoro.Ona Tafura 4 yehunhu hwekuwedzeredza kuwanda uye nguva yekuita.Nguva yekuremedza kuremedza kureba kunonoka kudzivirira maitiro curve ndeye fekitori yakaiswa paF2

4.5.4 Undercurrent Protection

Kudzivirirwa kwepasirezvino: Inoenderana nereshiyo yehushoma ikozvino kune yakayerwa ikozvino kuti uone kana ichimisikidza iyo undercurrent dziviriro (iyo fekitori marongero i60%).Iko kushanda ikozvino le yeCPS yakangwara kusunungurwa, kuitira kuti motokari irege kupinda mukati mekudzivirira kweCPS.

Kana iyo yazvino iri pasi peiyo yakatarwa kukosha kweiyo undercurrent kuchengetedzwa, nguva yekuita ishoma pane kana yakaenzana ne30 masekonzi.

4.5.5 Zvitatu-chikamu chisina kuenzana (chakaputsika, chisipo) kudzivirira

Kudzivirirwa kwenhatu-phase unbalance kunobva pachiyero chemusiyano pakati pehupamhi uye hushoma huripo kusvika kune yakanyanya ikozvino kuti uone kana kutanga iyo-nhatu-nhanho unbalance (kuputsa, chikamu kurasikirwa) kudzivirira.

(Kusagadzikana mwero = (yepamusoro ikozvino - shoma ikozvino>/ yakanyanya ikozvino)

Kana mutsauko wechero nhanho mbiri-yezvino kukosha inodarika 20 ~ 75% (iyo fekitori yekumisikidza iri 60%), nguva yekumisikidza chiito ishoma pane kana kuenzana ne3 masekonzi.

4.5.6 Dziviriro yekutandarira

Yakakiyiwa-rotor dziviriro ndeyekudzivirira mota kubva pakupisa uye kukuvadza mota nekuda kwekuvharika kwekushanda kwakakomba kwemidziyo yekutyaira kana kushanda kwakawandisa kwemota.Kazhinji, kushanda ikozvino kunosvika pamutengo wakatarwa kutonga kana kumisa iyo yakakiyiwa-rotor kudzivirira.

Apo kushanda ikozvino kunosvika 3.5 ~ 8 nguva dzemazuva ano, nguva yekuita ishoma kudarika kana yakaenzana ne 0.5 seconds.

4.5.7 Short circuit short kunonoka kudzivirira

Apo kushanda kwemazuva ano kunosvika kudarika 8 nguva dzemazuva ano yakatarwa, nguva yekuita ishoma kudarika kana yakaenzana ne 0.2 seconds.

5.1 Panel Ratidza uye Kiyi Mirairo

Pamberi peCPS yakasimbiswa uye yakavharwa, kunonoka kwenguva refu uye kunonoka-kunonoka kugadzirisa mafungu kunofanira kuiswa kune zvinodiwa zvinodiwa maererano nemutsara wekutakura ikozvino inodzora uye inodzivirira.Mushure mekunge simba rabatidzwa, iyo dhijitari chubhu inovhenekera kumusoro, inoratidza yekubatsira ikozvino uye voltage kukosha, uye cyclic inoratidzira yakatariswa inoshanda ikozvino kukosha kweiyo A, B, uye C matatu-chikamu maseketi.

5.2 Kumhanya mashandiro

Kuisa kiyi: Kana mutoro usiri kushanda, dzvanya kiyi iyi kuti uise iyo mamiriro eparameta

Shift kiyi: Sarudza iyo yakasetwa yezwi bhiti mune yekumisikidza mamiriro, uye yakasarudzwa izwi bhiti riri mukubwaira

Data kiyi: Shandura iro rinopenya izwi bit.Musiyano welevel ndeye 1 {0 kusvika 9 mitsetse}

Reset kiyi: Kana iyo parameter yapera, tinya kiyi iyi kuchengetedza iyo parameter uye woiisa mune yakajairika yekutarisa maitiro ekuita.

5.5.1 Mushure mokunge CPS yakabatanidzwa kune simba rekushanda, LED inoratidza kukosha kwevheji, iyo inogonawo kushandiswa se voltmeter, uye nhamba nhatu dzekupedzisira dzinoratidza kukosha kwevheji.

5.5.2 CPS inogonawo kushandiswa seammeter panguva yekushanda kuratidza matatu-phase ikozvino kushanda mumhepo.

Dzvanya "shift kiyi" kuratidza nenzira yazvino chimiro chekuwedzera cheA-phase, B-chikamu, C-chikamu uye L (kudonha).

Dzvanya "reset kiyi" kuti utangezve kutenderera kuratidzwa kweiyo-chikamu chetatu kushanda ikozvino.

5.2.3 Kugadzirisa matambudziko

Kwete-kuremerwa kushanda kweCPS, dzvanya "data kiyi", enzanisa nechiratidzo chemhando yekukanganisa pane pani, unogona kutarisa mhando nhatu dzekutanga dzekutadza;kana kukosha kwevoltage kunoratidzwa, zvinoreva

Iyo CPS yabuda mubvunzo wekukanganisa uye inoiswa mune yakajairwa yekutarisa maitiro ekushanda: kana tangazve iyo CPS kuti ibude pane yekukanganisa.

5.3 Dziviriro parameter marongero

Kana mota ichitanga uye ichimhanya, kudzvanya kiyi yekumisikidza hakuna kunaka;

Hapana-mutoro unomhanya cps: dzvanya "set kiyi" kuti usarudze kuseta mhando, dzvanya "shift kiyi" uyezve, sarudza data shift, dzvanya "data kiyi" kugadzirisa data;

Mushure mekunge parameter yaiswa, dzvanya "set kiyi" zvakare kuti upinde inotevera mamiriro ekugadzirisa, kusvika kumagumo;

Sarudzo isingadikanwi inofanira kusiya marongero.Mushure mekunge ma paramita ese aiswa, dzvanya kiyi reset kuti ubude mumamiriro ekuisa uye kuratidza kukosha kwevoltage.
