Zvese Zvaunoda Kuziva Nezve PDU PCBs

ziviso

Munyika yemagetsi uye manejimendi emagetsi, izwi rekuti "PDU PCB" rinogona kunge risingazivikanwe seimwe tech jargon, asi rinoita basa rakakosha mukuona kugovaniswa kwakanaka kwesimba remagetsi. Iyi blog post ine chinangwa chekuburitsa pfungwa yePDU PCBs, kuongorora zvavari, mashandiro avanoita, uye kukosha kwavo mumashandisirwo akasiyana siyana.

Chii chinonzi PDU PCB?

A PDU PCB inowanzo wanikwa mukati mePower Distribution Unit (PDU), inova mudziyo wemagetsi unoshandiswa kugovera magetsi kune akawanda zvitoro kana zvishandiso munzvimbo dzedata, server racks, kana mamwe maIT nharaunda. Iyo PDU PCB inoita basa rakakosha mukufambisa yakachengeteka uye inoshanda kugovera kwesimba mukati mePDU.

Iyo PDU PCB ine basa rekupa inodiwa magetsi ekubatanidza, dunhu, uye zvikamu zvinoita kuti PDU igovane simba nemazvo. Inosanganisira zviteshi, nzira dzekufambisa dzakaiswa paPCB pamusoro, dzinotakura magetsi kuenda kunzvimbo dzakasiyana dzePDU. Aya maronda akanyatsogadzirirwa kubata simba rekutakura uye zvinodiwa zvePDU, kuve nechokwadi chekushanda kwakakwana uye kuderedza kurasikirwa kwemagetsi.

Iyo PDU PCB inosanganisirawo akasiyana zvikamu uye maficha kutsigira simba rekugovera uye manejimendi mabasa. Izvi zvinogona kusanganisira magetsi ekuisa zvibatanidza, zvinobuditsa zvibatanidza zvekubatanidza midziyo, magetsi ekudzora zvikamu zvakadai semagetsi ekudzora uye anomira zvino, maseketi ekudzivirira akadai seanodzivirira ekudzivirira uye fuse, uye yekutarisa nekudzora maseketi ekuyera voltage, ikozvino, uye mamwe ma paramita.

Magadzirirwo nemarongerwo ePDU PCB zvinhu zvakakosha kufunga nezvazvo. Zvinhu zvakaita sehukobvu, upamhi, uye nzvimbo zvinoongororwa nokungwarira kuti zvibate mutoro wemagetsi uye kuderedza kuramba kwemagetsi, izvo zvinobatsira kuchengetedza kugoverwa kwemagetsi kwakasimba uye kudzivirira kupisa zvakanyanya kana kudzikira kwemagetsi. Pamusoro pezvo, dhizaini yePCB inogona kusanganisira matekiniki ekutonga kupisa kuti ibvise kupisa kunokonzerwa nemaitiro ekugoverwa kwemagetsi zvinobudirira.

Zvakare, iyo PDU PCB inogona kusanganisira zvinhu zvekusimudzira kuchengetedzwa, senge zvipingamupinyi zvekuzviparadzanisa pakati peakakwira-voltage uye yakaderera-voltage nzvimbo, uye kutevedzera akakodzera kuchengetedza zviyero nemirau. Aya matanho anobatsira kudzivirira panjodzi dzemagetsi uye kuona kuti PDU inoshanda zvakachengeteka.

Muchidimbu, PDU PCB inyanzvi yakadhindwa yedunhu bhodhi rakagadzirirwa magetsi ekugovera zvikamu. Inopa anodiwa magetsi ekubatanidza, dunhu, uye zvikamu zvekufambisa zvinobudirira uye zvakavimbika simba rekugovera mukati mePDU. Kuburikidza nekungwarira dhizaini uye kuita, iyo PDU PCB inova nechokwadi chekushanda kwakakwana, kuchengeteka, uye kuomerera kune zviyero zvemagetsi mumashandisirwo emagetsi ekutonga.

Zvikamu zvePDU PCB

Power Distribution Unit (PDU)

• • Chikamu chePDU chiri mukati mePDU PCB chine basa rekugovera chaiko kwesimba remagetsi. Mumamiriro ezvinhu akasiyana, maPDU anoshandiswa kudzora uye kugovera simba kune akasiyana zvikamu kana masisitimu.
  • MaPDU anowanzo kuwanikwa munzvimbo dzedata, nharaunda dzenetiweki, kuseta maindasitiri, uye mamwe marongero apo michina yemagetsi yakawanda inoda yakagadzikana uye inodzorwa magetsi.

Yakadhindwa Circuit Board (PCB)

• • Iyo PCB ndiyo hwaro hwemuviri hwePDU, ichipa chikuva chekumisikidza nekubatanidza zvinhu zvemagetsi.
  • MaPCB anogadzirwa achishandisa isiri-conductive substrate, inowanzo gadzirwa nefiberglass, pane inoitisa maturu, mapadhi, uye mamwe maficha akaiswa uchishandisa machira emhangura.
  • Idzi nzira dzekufambisa dzinobvumira kuyerera kwemagetsi masaini uye simba pakati pezvikamu zvePDU PCB.

Inoshanda Zvimiro zvePDU PCBs

PDU PCBs dzakagadzirirwa kuzadzisa huwandu hwemabasa akakosha ane chekuita nekugovera magetsi uye manejimendi. Heano mamwe emabasa akakosha uye maficha:

Power Connectors

• • PDU PCBs dzakashongedzerwa nemagetsi ekubatanidza ayo anoshanda senge interface pakati pekunze magetsi masosi uye yemukati wedunhu remudziyo kana system.
  • Aya makubatanidza anoita basa rakakosha mukugamuchira simba rinouya uye nekuriparadzira zvinobudirira kune akasiyana zvikamu kana subsystems.

Dziviriro Matunhu

• • Kuchengetedza kubva kune zvinogona kukuvadza pamusoro pemamiriro ezvinhu kana kutadza kwemagetsi, PDU PCBs dzinowanzobatanidza nzira dzekudzivirira dzakadai semafuse kana mabreaker circuit.
  • Aya maseketi ekudzivirira anoita semutsetse wekutanga wedziviriro, achibvisa dunhu kana pakaitika simba rekuwedzera kana kuwandisa, kudzivirira kukuvadzwa kwemidziyo yakaoma.

Power Conditioning Zvikamu

• • Kugovera kwemagetsi kwakachena uye kwakagadzikana kwakakosha pakushanda kwakavimbika kwemagetsi masisitimu. PDU PCBs inogona kusanganisira magetsi ekugadzirisa zvinhu senge mafirita kana voltage regulators.
  • Mafirita anoshandiswa kubvisa ruzha rusingadiwe rwemagetsi, kuve nechokwadi chekuti simba rinopihwa harina kuvhiringwa zvinogona kukanganisa midziyo inorema.

Kudzora Circuitry

• • Mazhinji maPDU PCB anoratidza sophisticated control circuitry, iyo inogona kusanganisira microcontrollers kana mamwe maitiro akangwara ekudzora.
  • Aya maseketi ekudzora ane basa rekutonga kugovera kwemagetsi, kutarisa mitoro iripo, uye, mune dzimwe nguva, kuita kudzora kure uye kutarisa mashandiro.

Zvikumbiro uye Kukosha

PDU PCBs inowana kushandiswa mune dzakasiyana siyana maindasitiri uye zvigadziriso uko kugovera kwemagetsi kwakakosha kwakakosha. Heino mimwe mienzaniso yekukosha kwazvo:

Nzvimbo dzeData : Munzvimbo dzedata, uko kushanda kusingadzoreki kwakakosha, maPDU PCB anoita basa rakakosha mukuona kuti maseva, michina yekubatanidza, uye masisitimu ekuchengetera zvinhu anowana magetsi asingaperi uye akagadzikana.

Kuzvigadzira Kwemagetsi Mumaindasitiri : Kuzvigadzira kwemagetsi mumaindasitiri kunoshandisa maPDU PCBs pakupa simba nekutonga mashandiro emichina nekugadzira. Anopa simba rinodiwa uku achidzivirira kubva kumatambudziko emagetsi.

Kukurukurirana : Chikamu chekutaurirana chinovimba nemaPDU PCB kuti zvirambe zvichienderera mberi nekushanda kwezvivakwa zvekutaurirana. Mabhodhi aya anovimbisa kuti network dzinoramba dzichishanda pasina kukanganiswa.

mhedziso

Kazhinji, maPDU PCB anogona kushanda pachivande, asi akakosha pakugoverwa kwesimba remagetsi kwakavimbika uye kwakanaka mumasisitimu akasiyana-siyana emagetsi. Basa rawo mudata centers, maindasitiri otomatiki, kutaurirana, uye mamwe maindasitiri akakosha harigone kupfuudzwa zvakanyanya. Sezvo tekinoroji ichiramba ichifambira mberi, maPDU PCB acharamba achichinja, zvichiita kuti nyika yedu iri kuramba ichibatana iwane simba rainoda kuti ishande zvakanaka.

Kuti uwane ongororo yakakwana yekugadzira, shandisa chinyorwa chino pamwe chete nehurongwa hwekudzivirira kwe overcurrent uye controlled impedance PCB pakutarisa zvinodiwa zve stackup, assembly, kana bvunzo.
