Main Function

Basa guru remagetsi regulator.
1. Kugadzikana kwemagetsi.
Kana iyo grid voltage ichichinja ipapo ipapo, iyo voltage regulator inotsiva iyo voltage amplitude nekumhanya kwekupindura kwe10-30ms, ichiita kuti igadzikane mukati me ± 2%.
2. multi-functional integrated protection.
Iyo voltage regulator mukuwedzera kune yakanyanya kudzikamisa yevoltage basa inofanirwawo kuve nekudzivirira kwekuwedzera (kupfuura +10% yemagetsi anobuda), pasi-voltage dziviriro (isingasviki -10% yemagetsi anobuda), chikamu chekutadza kuchengetedza. , pfupi redunhu remedu yekudzivirira iyo inonyanya kukosha yekudzivirira mabasa.
3. Spike pulse suppression (optional).
Iyo grid yemagetsi dzimwe nguva ine yakakwira amplitude, iyo pulse hupamhi ndeye yakatetepa spike pulse, uye ichapwanya nepakati yakadzika voltage inomira zvinhu zvemagetsi.Izvo zvinorwisa-kuvhiya zvikamu zvemagetsi akadzorwa anogona kuita basa rakanaka kwazvo mukudzvanya mapurusi akapinza akadaro.
4. Kuzviparadzanisa nevamwe conductive EMI electromagnetic interference (optional).
CNC midziyo yakawanda AC/DC rectifier + PFC yakakwira-frequency simba factor kururamisa, pachayo imwe huwandu hwekuvhiringidza panguva imwe chete iyo sosi yekukanganisa ine zvakare yakasimba zvinodiwa.Yakadzorwa magetsi ekupa mafirita emagetsi anogona kunyatso paradzanisa grid kupindira kune michina panguva imwe chete inogonawo kunyatso paradzanisa kukanganiswa kwemidziyo kune grid.
5. kudzivirira mheni (optional).
Inofanirwa kuve nekwaniso yekudzivirira kubva pakurohwa nemheni.

Iyo DC voltage regulator inogona kukamurwa kuita mapoka maviri.

1, shanduko yemhando
Rudzi rwakasiyana rwekudzikamisa magetsi kubva kune linear regulated simba rekupa ndeye switching type DC inodzorwa magetsi, iyo ine dunhu rerudzi rwe-single-ended flyback, imwechete-inopera kumberi, hafu-bhiriji, kusunda-kudhonza uye yakazara-zambuko.Musiyano wakakosha pakati peichi uye mutsara magetsi emagetsi ndewekuti transformer haishande pamafambisirwo ekushanda asi makumi e kilohertz kune akati wandei megahertz.Basa rekushanda chubhu haisi kushanda munzvimbo yekuzadza uye yakachekwa-iyo ndiyo inoshandura mamiriro;switching power supply saka zita.

2, Linear
Iyo linear voltage regulator ine chinhu chakajairika mukuti simba rayo regiyo regulator chubhu rinoshanda mumutsara zone, richivimba nekudonha kwevoltage pakati pechubhu regulator kudzikamisa zvinobuda.Nekuda kwekurasika kwakakura kweiyo regulator chubhu, hombe yekudziya sink inoda kuiswa kuti ibvise kupisa kwairi.Iyo transformer inorema zvakare nekuti inoshanda pa50Hz.

Zvakanakira zverudzi urwu rwemagetsi kugadzikana kwakanyanya, diki ripple, yakakwirira kuvimbika, nyore kuita yakawanda, inoenderera ichigadziriswa kubuda kwechigadzirwa chakapedzwa.Izvo zvisingabatsiri ndezvekuti dzakakura, dzakakura, uye hadzina kunyatsoshanda.Iri rudzi rwemagetsi akagadzikana uye kune marudzi mazhinji, kubva kumhando yekubuda inogona kukamurwa kuita voltage yakagadzika magetsi uye ikozvino yakagadzikana magetsi uye seti yemagetsi kudzikamisa, ikozvino kugadzikana mumhepo yakagadzikana, uye ikozvino (yakagadzikana-yakagadzikana. ) magetsi.Iko kukosha kwekubuda kunogona kukamurwa kuita yakagadziriswa-poindi yekubuda magetsi, bhendi switch-inogadziriswa, uye potentiometer inoramba ichigadziriswa mhando yakati wandei.Kubva pane zvakabuda, chiratidzo chinogona kukamurwa kuva pointer chiratidzo mhando uye dijitari yekuratidzira mhando, zvichingodaro. 三、

Introduce

DC inoshandura magetsi emagetsi.
Zvakanakira zvekuchinja magetsi saizi diki, huremu, kugadzikana, uye kuvimbika.Iwo anowanikwa mumagetsi emagetsi kubva kune mashoma watts kusvika kune akati wandei kilowatts.Heano mashoma ekuchinja magetsi emagetsi
1. Kukurukurirana magetsi
Iyo magetsi ekufambisa magetsi ndeye DC/DC inoshandura mhando yemagetsi, asi kazhinji ndeye DC-48V kana -24V magetsi, uye bhatiri rekuchengetedza remagetsi eDC, iyo DC yemagetsi magetsi mumagetsi ebasa redunhu, kazhinji. yakakamurwa kuva pakati pesimba rekupa, akaturikidzana magetsi, uye imwe-bhodhi magetsi emagetsi matatu, ekupedzisira ndiyo yakavimbika.
2. AC/DC
Mhando iyi yemagetsi, inozivikanwawo seyekutanga magetsi, inowana simba kubva kune gidhi remagetsi uye inowana DC yakakwira voltage kuburikidza nehupamhi hwemagetsi kugadzirisa uye kusefa iyo DC/DC inoshandura kuti iwane imwe kana akati wandei akagadzikana DC voltages pane inobuda, ine simba rinobva pawatts shoma kusvika kune akati wandei kilowatts.Kune huwandu hwakasiyana hwezvakatemerwa zvezvigadzirwa zvakadaro, uye iyo yekutanga magetsi (AC220 yekuisa, DC48V, kana 24V kubuda) mumagetsi ekutaurirana ndeyemhando iyi, zvichienderana nezvinodiwa nemushandisi.
3. Modular simba rekupa
Nekukurumidza kukura kwesainzi uye tekinoroji, kuvimbika kwesimba rekupa, uye huwandu / huwandu hwehuwandu huri kuramba huchikwira, iyo module yemagetsi iri kuwedzera kuratidza hukuru hwayo, inoshanda pamhepo yakakura, saizi diki, kuvimbika kwepamusoro, kuiswa nyore. uye musanganiswa wekuwedzera, saka zvakanyanya uye zvakanyanya kushandiswa zvakanyanya.Kunyangwe paine inoenderana yemumba module kugadzirwa, nekuti maitiro ekugadzira haana kusvika pamwero wepasirese, mwero wekutadza wakakwira.
4. Redhiyo magetsi
Radio magetsi ekuisa AC220V/110V, inobuda DC13.8V, simba nesimba reredhiyo, mashoma amps, uye mazana emaamps aripo.Kudzivirira iyo AC grid simba kutadza kukanganisa basa reredhiyo, uye inoda kuve nebhatiri paki se backup, saka iyi mhando yemagetsi ekuwedzera kune kubuda kweiyo 13.8V DC voltage inewo bhatiri rinochaja otomatiki kushandura basa.
5. DC/DC
Muchirongwa chekutaurirana, inozivikanwawo sechipiri chemagetsi, isimba rekutanga magetsi kana DC bhatiri paki yekupa DC yekupinza voltage, mushure mekushandurwa kweDC/DC kudivi rekubuda kuti uwane DC voltage kana akati wandei DC voltages.
Kunyangwe iyo DC/DC module magetsi inodhura zvakanyanya, kubva pakuona kwemutengo wakazara wechigadzirwa chenguva refu yekushandisa kutenderera, kunyanya nekuda kwekutadza kwehurongwa uye mutengo wakakura wekugadzirisa uye kurasikirwa kwekunaka, sarudzo yemagetsi module. ichiri kudhura-inoshanda, inofanirwawo kutaurwa pano ndiyo Roche inoshandura dunhu, mukana wayo wakatanhamara ndiyo yakapfava chimiro chedunhu, kushanda kwepamusoro uye kubuda kwemagetsi uye ikozvino ripple kukosha pedyo ne zero.
6. Zvigadzirwa zvemagetsi zvakakosha
High voltage uye yakaderera ikozvino magetsi emagetsi, akakwira emagetsi emazuva ano, 400Hz yekuisa AC/DC magetsi emagetsi, nezvimwe zvinogona kuiswa sezvizvi uye zvinogona kusarudzwa zvinoenderana nezvinodiwa.
