1. Isingeniso

ZK uhlobo SCR voltage Regulator isetshenziswa ne SCR, kungaba ulungise umthwalo Ukushisa amandla, isigaba-eshintshashintshayo nokucupha imodi babe ukujula voltage impendulo engeyinhle, ngakho has a ukulungiswa komugqa ezinhle, umthelela inethiwekhi nenze umsindo oshintshashintshayo kuyoba uye kulencane kakhulu. Zero-Ukunqamula nokucupha design ithuluzi imodi sika babe inethiwekhi voltage ukuguquguquka isinxephezelo umsebenzi, kubuyele esimweni esivamile ezahlukene amandla voltage Ukushisa amandla

2. Izimpawu

2.1 Umklamo esanda, indiza esakhelwe ammeter enkulu okukhiphayo inkomba, akucace ukufunda ulungise umshini zero. ukujula Insimbi wanquma ukukhiqizwa evamile phansi nesigamu kunenkulumo, isisindo ekhanyisa 2kg, isici ukushaqeka ukumelana muhle, anti-wenza umcimbi ikhono luqinile.

2.2 Lapho mthwalo short circuit noma overcurrent, insimbi ungavala ngokuzenzakalela isignali inhlamvu SCR e-1 ~ 2 isikhathi, ake SCR baphathe lamanje futhi bavikele ekulimaleni, ngesikhathi esifanayo ibe inkomba umsebenzi lapho umthwalo short circuit.

2.3 ngokuqondile uthole kokuvumelanisa amasignali kusukela kunethiwekhi, kusebenza "Y" indlela uxhumano, ukulawula uzinzile futhi ethembekile.

3. Model incazelo :  ZK uhlobo SCR voltage (amandla isilinganiso)  regulator

Usayizi iyunithi (mm) yangaphandle usayizi Faka usayizi usayizi yangaphandle Faka usayizi

  Single phase voltage Regulator ZK-1: 160 × 80 × 130; 152 × 76; ZKA-1: 96 × 96 × 130; 92 × 92   

izigaba ezintathu voltage Regulator ZK-3: 160 × 80 × 130; 152 × 76; ZKA-3: 96 × 96 × 130; 92 × 92  

4. Main izinkomba technical :

4.1 isignali wokufaka: 0 ~ 10mA (wokufaka impedance  800Ω)or 4~20mA(Input Impedance 250Ω);

4.2 lokukhipha ishayela: Inani Amplitude akuyona esingaphansi 3V, Ububanzi akuyona esingaphansi 50uS (20Ω umthwalo);

4.3 Isigaba - shift kuvuse esiphezulu conduction engela: hhayi ngaphansi kuka-150 °;

4.4 Ukusebenza imvelo:

Izinga lokushisa: 0 ~ 50 ℃, isihlobo humidity≤85%, ngaphandle adle futhi eqinile emisebeni kagesi;

4.5 Amandla kagesi: AC220V ± 15%, 50Hz mayelana 3VA

4.6 Isisindo: mayelana 0.8Kg

5. Ukufakwa :

5.1 Hlola izesekeli ithuluzi: ngezikulufo ezimbili obandayo, amapulangwe amabili obandayo;

5.2 Xhuma okokufaka, okukhipha (SCR ukulawula electrode sika G1, G2 futhi K) 1, K2), impendulo, amandla, phansi lesithando izintambo ngokuvumelana esifakiwe.

5.3 Lapho zamukela "Y" indlela uxhumano, SCR sika simelane nokucindezelwa Kufanele ube ngaphezu 600V. zamanje SCR sika ukalwe kumele kube izikhathi ezingaphezu kuka-1.5 practical usebenzisa imisinga kagesi. SCR kumele kusetshenziswe kurediyetha endaweni enkulu ngokwanele, futhi unake emoyeni ukupholisa, siqinisekise ukuthi lokushisa SCR sika kungaqali excees120 ℃ ngaphansi kwanoma yimuphi umbandela. Lapho ukulawula indlela inxenye-elawulwa, diode sika simelane nokucindezelwa, Inkomba zamanje yilezi njengoba isigaba esisodwa SCR.

5.4 ezintathu fuses (exhunywe serially anode SCR sika)  need connect phase line input terminal, and shall not connect other locations.

5.5 Uma kurediyetha le SCR liyaphila, lapho ufaka, kufanele bazicabangele ngokugcwele zonke ekuvimbeni ukungenwa shock ngogesi futhi short circuit phakathi SCR.

5.6 Uma amperemeter Connect, kumele uxhume serially anode SCR sika, ungavumeli hambisa isignali inhlamvu ngokusebenzisa amperemeter.

5.7 Njalo SCR sika isignali inhlamvu umugqa nezinye izintambo kufanele kube wiring ahlukene, ukuvimbela interfereing nomunye futhi kuholele SCR inhlamvu ukuthi ingase ilahlekelwe ukulawula.

6. Operating nokulungisa :

6.1 Beka "manual ~ okuzenzakalelayo" yokuguquguqula inkinobho kuya "manual" isikhundla, ujike kwewashi le "manual isiqondiso" spin ku iphaneli, ixhunyiwe inkinobho amandla, ukukhanya amandla Inkomba kuyinto inkinobho ukukhanya, insimbi ingasebenza.

6.2 Lungisa "isiqondiso manual" spin ku iphaneli, khomba esithandweni Ukushisa voltage ammeter Ukufundwa kuzokhulisa kusukela 0 kuya ku-90% mayelana ke wehlise ammeter ukufundela 40% mayelana, linda isikhashana, isithando somlilo lokushisa  increase, it means that the instrument manual work normally.

6.3 Uma insimbi abambisane imitha kokuba zamanje okukhipha P.ID ukulungisa, ukubeka "manual ~ okuzenzakalelayo" yokuguquguqula inkinobho kuya "okuzenzakalelayo" isikhundla, umthwalo Ukushisa voltage ngokuzenzakalelayo elawulwa PID ngokulungisa okuphumayo Inani lamanje imitha sika. 

6.4 Beka "manual ~ okuzenzakalelayo" yokuguquguqula inkinobho kuya "manual" isikhundla, ulungise "isiqondiso manual", kayiphothi; Ukushisa voltage is kushintshwe ukubaluleka ezidingekayo, okwamanje umsebenzi insimbi ufana inhlukano voltage Regulator.

6.5 Uma umthwalo design Ukushisa amandla likhulu, noma izinga lokushisa ongaphakeme ongaphakeme yangaphakathi impedance into ukushisa kokuqala, ungakwenza kube nomkhawulo esiphezulu Ukushisa amandla ngokulungisa "impendulo" potentiometer ku iphaneli, okwamanje ibonisani okukhipha ammeter Ukufundwa inciphe, kungaba ukuvikela umthwalo noma SCR ekubeni kabana wamanje. Ezimweni jikelele,  put the instrument to  the “automatic” function, when full input(if 10mA), adjust the “feedback” potentiometer again, let load voltage value subject to 90% of supply voltage.

6.6 Musa ukushayela umthwalo exhasa, ezifana lokungeniswa somlilo, ushiya phansi transformer, gwema SCR umonakalo.

6.7 Uma isigaba SCR ukuziphatha bengayi ngokugcwele noma okukhipha Shake sina, ungase uyishintshe  the phase  trigger signal output connection.

6.8 Into yonke yangaphakathi ukulungiswa potentiometer zidluliselwe ngaphambi kokushiya kwemboni, ezimweni jikelele, musa ukudlulisa okungahleliwe.

7. Wiring umdwebo ( uthintane ):

1

ZK-1 ezimbili ngendlela SCR isigaba-eshintshashintshayo nokucupha ZK-1one indlela SCR isigaba-eshintshashintshayo nokucupha

2

ZK-3 ezimbili ngendlela SCR isigaba-eshintshashintshayo nokucupha

Ukuze uvimbele SCR kusuka mzuzu high voltage ukuwohloka, ukumelana R kanye capacitance C kukhona RC ukuncela inethiwekhi wesifunda, R 1.5Ω / 0.5W Carbon-Film Resistor, C 0.1μf / 630VAC non-inductively polyacrylamide capacitance.
