Sei mazhinji emagetsi ekutaurirana anoshandisa -48V magetsi ekupa?

Mukutaurirana, tinowanzoona kuti mazhinji emagetsi ekutaurirana anofambiswa ne -48V. Muchokwadi, kune zvikonzero zvakawanda uye kufunga kune chiyero chakadaro. Pano isu tichakurukura zvakadzama kuti nei mazhinji emagetsi ekutaurirana -48V magetsi ekupa, uye nhevedzano yenyaya dzine hukama.

1iye kupatsanurwa kwesimba rekushandisa
Mukunzwisisa kuti sei magetsi ekutaurirana ari -48V, isu tinotanga taziva kupatsanurwa kwesimba rekushandisa. Simba rekushandisa, ndiko kuti, rinochinjika rinoshandiswa muhupenyu hwedu hwezuva nezuva, rinowanzo kupatsanurwa muzvikamu zvinotevera:
Single-phase simba: inosanganisira imwe tambo yemoto uye imwe zero wire, uye magetsi anowanzo 220 V. Inonyanya kushandiswa mudzimba uye nzvimbo duku dzekutengesa.
Matatu-chikamu simba: inoumbwa nematare matatu emoto uye imwe zero wire, uye voltage inowanzoita 380 V. Inoshandiswa zvakanyanya mumaindasitiri, nzvimbo huru dzekutengeserana, nezvimwewo.
Seimwe yenzvimbo dzekuisa yekutaurirana magetsi, simba rekushandisa rinoda kuenda kuburikidza neyakatevedzana yekushandura uye kugadzirisa kuitira kuti ipe yakagadzikana uye yakavimbika DC magetsi emidziyo yekutaurirana.

2.-48V magetsi ekupa nzira yekugadzira?
Kazhinji, chizvarwa che -48V magetsi emagetsi anogona kutsanangurwa mune inotevera maitiro: Utility yekuisa: Chekutanga pane zvese, zvinoshandiswa zvinopinzwa muhurongwa hwemagetsi ekutaurirana. Utility inogona kuva 220V kana 380V AC. Kugadziriswa: Iyo AC inofanirwa kuchinjirwa kuDC neanogadzirisa. Rectifiers anoshandisa diode uye zvimwe zvikamu zvemagetsi, shandura iyo yakanaka uye yakaipa hafu ye AC kuenda kune imwechete nzira yeDC.
Kuchengeta: ma ripples uye tsvina zvinosefa kubva kuDC yakagadziridzwa kuitira kuti iyo DC ive yakatsetseka uye yakagadzikana. Voltage Kudzikamisa: kudzikamisa iyo DC voltage pa -48V kuburikidza neiyo voltage stabilizer wedunhu, iyo inogona kugadzirisa otomatiki magetsi ekubuda zvichienderana nekuchinja kwemutoro kuti ive nechokwadi chekuti michina yekutaurirana inogara ichiwana yakagadzikana magetsi. Mushure mekufamba nematanho ari pamusoro, munhu anogona kugadzira iyo -48V yekutaurirana magetsi.

3.Nei -48V magetsi ekupa? Panzvimbo ye +48V
Nhaurirano magetsi ekupa -48V magetsi panzvimbo ye +48V, kunyanya nekuda kwezvikonzero zvinotevera:
Zvikonzero zvekare
Mukutanga kutaurirana masisitimu, machubhu emagetsi nemimwe michina inoda simba repamusoro kuti rishande. Kuti ive nechokwadi chekugadzikana uye kuvimbika kwemidziyo, -48V yakasarudzwa seyakajairwa voltage yemagetsi ekutaurirana. Iyi mwero yakatakurwa sezvo tekinoroji yekutaurirana yakaramba ichikura.
Midziyo yekutanga senge nhare dzekuchinjana dzakashandisa magetsi emagetsi, ayo anoda shanduko huru mune zvazvino kana vakabatikana uye kubviswa. Kushandiswa kwe-48V magetsi kunogonesa kuti relays ive nediki diki mutsauko padzinenge dzakabatikana uye dzisina kuvharwa, nekudaro kuvandudza kuvimbika uye kugadzikana kwemidziyo.
Safety Factors
Iyo yakachengeteka voltage yemuviri wemunhu inowanzoonekwa se36V kana zvishoma. Iine -48V inopa, kana iri mhosva yepasi, zvichingodaro, ikozvino inoyerera ichienda pasi kuburikidza nepasi rekudzivirira pasina njodzi yakananga yekuvhundutsa kumuviri wemunhu. Nekupa + 48V, kana iri mhosva yepasi, ikozvino ichayerera ichibva mumuviri ichienda pasi, ichiwedzera njodzi yekuvhunduka kwemagetsi.
-48V masisitimu emagetsi anowanzo kugadzirwa nekuchengetedzwa kwepasi kuti awedzere kusimudzira kuchengetedzwa kwehurongwa. Kana kukanganisa kwepasi kuchiitika muhurongwa, chigadziro chekudzivirira pasi chichakurumidza kugura magetsi uye kudzivirira njodzi kubva pakuwedzera.
Factors dzehunyanzvi
Mune masisitimu ekutaurirana, zvigadzirwa zvemagetsi zvakawanda zvinoshandisa semiconductor midziyo yakadai sedhiodhi, transistors, uye maseketi akabatanidzwa. Iyi semiconductor michina inoda yakagadzikana magetsi ekupa magetsi ekushanda kwavo uye iri kudiwa zvakanyanya maererano neripple uye ruzha zvinodiwa kubva kune magetsi. Kushandiswa kwe -48V magetsi ekupa magetsi kunogona kupa semiconductor zvishandiso zvine simba rakagadzikana uye rakachena nekushandisa matekiniki akadai sevoltage regulator redunhu uye sefa redunhu kuitira kuti ivandudze mashandiro uye kuvimbika kwemidziyo.
Kuenzaniswa nekutapurirana uye kugovera kwesimba, iyo -48V magetsi emagetsi system ine diki kurasikirwa kwemutsara uye kudonha kwemagetsi. Izvi zvinodaro nekuti kana simba rakafanana, iro diki voltage, yakakura ikozvino, uye kurasikirwa kwemutsara kunoenderana neskweya yezvino. Saka, kushandiswa kwe-48V magetsi ekugadzirisa kunogona kuderedza kurasikirwa kwemutsara uye kusimudza kushanda kwekufambisa kwemagetsi.

4.Ndeupi musiyano uripo pakati -48V uye +48V?
Pane misiyano yakati wandei pakati -48V uye +48V:
Yakasiyana polarity
Uyu ndiwo mutsauko wakajeka zvikuru. -48V zvinoreva kuti danda rakashata remagetsi i -48V maererano nepasi, nepo +48V zvichireva kuti danda rakanaka remagetsi i +48V maererano nepasi.
Misiyano Yekuchengetedza
Sezvambotaurwa, iyo -48V ine mupendero pamusoro peumwe wayo mumaonero ekuchengetedza sezvo pakaitika chikanganiso chepasi, yazvino inoyerera nemuchinjiro wepasi kuenda pasi pasina kukonzera kuvhunduka kwakananga kumuviri wemunhu. Nepo, kune rumwe rutivi, kana paine chikanganiso chepasi mu +48V, ikozvino inowana nzira yayo kuenda pasi kuburikidza nemuviri wemunhu uye nekudaro inowedzera mukana wekubatwa nemagetsi.
Unhu hunhu
Mukugadzira masisitimu ekutaurirana, pane zvishandiso zvinogona kuda chaiwo polarities mumagetsi avo. Semuenzaniso, mamwe semiconductor zvishandiso zvinoshanda chete pasi pemamwe mapolarities. Nokudaro, iri panguva yekugadzira nzira yekukurukurirana iyo munhu anofanira kusarudza pakati pepolarities yemagetsi emagetsi pamusoro pezvinodiwa zvechigadzirwa.
Zvakare, zvinodiwa zvehunyanzvi zvekudzora magetsi, kusefa, uye kuchengetedzwa kwepasi kwemagetsi emagetsi masisitimu anogona kunge akasiyana kune -48V uye + 48V, pakati pezvimwe.

5.Ndedzipi nyika dzakatora -48V magetsi ekupa system?
Kunyangwe iyo -48V magetsi ekupa system ichishandiswa zvakanyanya mundima yekutaurirana, haasi ese matunhu epasi anotora iyo -48V magetsi. Nyika dzakasiyana nematunhu anogona kusarudza akasiyana emagetsi ekutaurirana zvinoenderana nemamiriro avo chaiwo uye zvavanoda.
Mune dzimwe nyika dzeEurope, semuenzaniso, a -60V kana imwe voltage level yemagetsi system inogona kugamuchirwa. Ndichiri munyika dzichiri kusimukira umo magadzirirwo emagetsi asina kusimba, hazvisi nyore kushandisa simba rinochinjika, senge solar nemhepo simba.
Nekudaro, nekudyidzana kwepasi rose kwehunyanzvi hwekutaurirana, nyika zhinji nematunhu ari kuita masisitimu emagetsi epasi rose ekufambisira mberi kuenderana nekudyidzana kwemidziyo yekutaurirana.

Mazhinji emagetsi ekutaurirana anotora -48V magetsi emagetsi anotemerwa nezvikonzero zvenhoroondo uye kuchengetedza chinhu uye tekinoroji zvinhu uye zvichingodaro. Kugadzirwa kwe -48V magetsi kwapfuura kuburikidza nekushandisa kwekushandisa, kugadzirisa, kusefa, uye kugadzikana kwemagetsi. Kuenzaniswa ne +48V, -48V ine humwe hukuru mukuchengetedza kuita uye tekinoroji maficha. Kunyangwe asiri matunhu ese epasi atora -48V magetsi ekupa masisitimu, nekuvandudza tekinoroji yekutaurirana, masisitimu epasi rose ekutaurirana magetsi achashandiswa zvakanyanya.
Mundima yekutaurirana yeramangwana, nekuenderera mberi nekuvandudza uye hunyanzvi hwetekinoroji, hurongwa hwesimba rekutaurirana hucharamba huchivandudza nekuvandudza. Tinogona kutarisira zvakanyanya kushanda, zvakachengeteka, uye zvakavimbika zvigadziriso zvesimba rekutaurirana kubuda, izvo zvinogona kutsigira zvakasimba kuenderera mberi kwekusimudzira kweindasitiri yekutaurirana.Sei mazhinji emagetsi ekutaurirana anoshandisa -48V magetsi ekupa?
