Chirongwa chipfupi chedzidzo chevanotanga nezve nei modular UPSs inotonhorera uye kuti yakaitika sei.
Zvichienderana nemavakirwo avo, simba risingachinjiki remagetsi enzvimbo dzedata rakakamurwa kuita mapoka makuru maviri: monoblock uye modular. Iyo yekutanga ndeyemhando yechinyakare yeUPS, iyo yekupedzisira ichiri nyowani uye yakanyanya kufambira mberi.
Ndeupi musiyano uripo pakati pemonoblock uye modular UPSs?
Mune monoblock isingapindiki magetsi emagetsi, simba rekubuda rinopihwa neiyo imwe simba unit. Mune modular UPSs, izvo zvakakosha zvinogadzirwa nenzira yemamodule akaparadzana, anoiswa mumakabati akabatana uye anoshanda pamwechete. Imwe neimwe yeaya mamodule akashongedzerwa ane control processor, charger, inverter, rectifier uye inomiririra yakazara-yakazara simba chikamu cheUPS.
Ngatitsanangure izvi nemuenzaniso wakapfava. Kana tikatora maviri asingapindiki magetsi emagetsi - monoblock uye modular - ine simba re40 kVA, ipapo yekutanga ichava nemodule imwe yemagetsi ine simba re40 kVA, uye yechipiri ichave ine, semuenzaniso, yemamodule mana emagetsi ane simba. ye10 kVA imwe neimwe.
Scaling options
Paunenge uchishandisa monoblock UPSs nekuwedzera kwekuda kwesimba, zvinodikanwa kuti ubatanidze imwe yakazara-yakazara unit yesimba rimwechete mukuenderana kune iripo. Iyi inzira yakaoma kunzwisisa.
Modular mhinduro dzinopa yakakura dhizaini kuchinjika. Mune ino kesi, imwe kana akawanda mamodule anogona kubatanidzwa kune yatove kushanda unit. Iyi inzira iri nyore inogona kupedzwa munguva pfupi.
Kugona kwesimba rakatsetseka kuwedzera
Kuwedzera kwakanaka kwesimba kwakakosha padanho rekutanga rekushandisa data center. Izvo zvine musoro kuti mumwedzi yekutanga ichave 30-40% yakatakurwa. Zvinonyanya kushanda uye zvine hupfumi kushandisa zvisingachinjiki magetsi emagetsi akagadzirirwa zvakanangana nesimba iri. Sezvo hwaro hwevatengi huchiwedzera, iyo data data data ichawedzera, uye nayo iyo kudiwa kwekuwedzera magetsi kuchawedzera.
Zviri nyore kuwedzera simba reUPS nhanho nhanho pamwe chete nehunyanzvi hwekuvaka. Paunenge uchishandisa monoblock uninterruptible magetsi emagetsi, kuwedzera kwakapfava kwesimba hakugoneke musimboti. Ne modular UPSs izvi zviri nyore kuita.
UPS kuvimbika
Patinenge tichitaura nezvekuvimbika, tichashandisa pfungwa mbiri: zvinoreva nguva pakati pekukundikana (MTBF) uye zvinoreva nguva yekugadzirisa (MTTR).
MTBF kukosha kweprobabilistic. Kukosha kwehuwandu hwenguva pakati pekukundikana kunobva pane zvinotevera postulate: kuvimbika kwegadziriro kunoderera nekuwedzera kwenhamba yezvikamu zvayo.
Mune iyi parameter, monoblock UPSs ine mukana. Chikonzero chacho chiri nyore: modular uninterruptible magetsi emagetsi ane zvimwe zvikamu uye zvibatanidza, chimwe nechimwe chinotorwa sechinhu chinogona kukanganisa. Saizvozvo, ne theoretically mukana wekukundikana wakakwira pano.
Zvisinei, nokuda kwemasimba asingapindiki anoshandiswa munzvimbo dze data, hakusi kukanganisa pachako kunokosha, asi kwenguva yakareba sei iyo UPS icharamba isingashande. Iyi parameter inotemerwa neiyo system's mean time yekudzorera (MTTR).
Pano mukana watove kudivi re modular blocks. Ivo vane yakaderera MTTR nekuti chero module inogona kukurumidza kutsiviwa pasina kukanganisa magetsi. Kuti uite izvi, zvinodikanwa kuti module iyi ive mustock, uye kubviswa kwayo uye kuiswa kwayo kunogona kuitwa nemumwe nyanzvi. Muchokwadi, hazvitore kupfuura maminitsi makumi matatu.
Ne monoblock uninterruptible magetsi anopa mamiriro acho akanyanya kuoma. Hazvizoitike kuzvigadzirisa nekukurumidza. Izvi zvinogona kutora kubva pamaawa akawanda kusvika mazuva akati wandei.
Kuti uone kukanganisa kushivirira kwehurongwa, unogona kushandisa imwezve parameter - kuwanikwa kana neimwe nzira kushanda. Ichi chiratidzo chakakwirira, iyo yakakwirira yenguva pakati pekukundikana (MTBF) uye yakaderera iyo system's mean time to recovery (MTTR). Formula inoenderana neinotevera:
pakati pekuwanikwa (kushanda) =
Nezve modular UPSs, mamiriro acho ndeaya anotevera: kukosha kwavo kweMTBF kwakaderera pane kwemonoblock UPSs, asi panguva imwechete vane MTTR yakaderera. Nekuda kweizvozvo, kuita kwe modular uninterruptible magetsi ekupa kwakakwira.
Simba rekushandisa
A monoblock system inoda zvakanyanya simba rakawanda nekuti yakawandisa. Ngatitsanangure izvi tichishandisa muenzaniso weN + 1 redundancy scheme. N ndiyo huwandu hwemutoro unodiwa kuti ushandise iyo data center midziyo. Muchiitiko chedu, tichaitora yakaenzana ne90 kVA. Iyo N + 1 chirongwa chinoreva kuti 1 reserve element inoramba isingashandiswe muhurongwa isati yatadza.
Paunenge uchishandisa monoblock isingapindiki magetsi ane simba re90 kVA, kuita iyo N + 1 dunhu, iwe unozofanirwa kushandisa imwe yakafanana unit. Nekuda kweizvozvo, iyo yakazara system redundancy ichava 90 kVA.
Paunenge uchishandisa modular UPSs ine huwandu hwe30 kVA, mamiriro acho akasiyana. Nemutoro wakafanana, kushandisa iyo N + 1 dunhu, iwe unozoda imwe module yemhando imwe chete. Nekuda kweizvozvo, iyo yakazara system redundancy haichazove 90 kVA, asi 30 kVA chete.
Nokudaro mhedziso: kushandiswa kwemagetsi emagetsi emagetsi kunogona kuderedza kushandiswa kwesimba kwe data data yose.
The Economy
Kana iwe ukatora maviri asingapindiki magetsi emagetsi akafanana, ipapo iyo monoblock imwe yakachipa kupfuura iyo modular imwe. Nechikonzero ichi, monoblock UPSs inoramba yakakurumbira. Nekudaro, kuwedzera simba rekubuda kunopeta mutengo weiyo system, nekuti imwe yakafanana unit ichafanirwa kuwedzerwa kune iripo. Mukuwedzera, pachava nechido chekuisa zvigamba zvepatch uye mabhodhi ekugovera, pamwe nekuisa mitsara mitsva yetambo.
Paunenge uchishandisa modular isingapindiki magetsi emagetsi, iyo system simba inogona kuwedzerwa mushe. Izvi zvinoreva kuti iwe uchafanirwa kushandisa mari pakutenga akati wandei ma module anokwana kugutsa izvo zviripo zvemagetsi zvinodiwa. Hapana zvisina kufanira stock.
mhedziso
Monoblock isingapindiki magetsi emagetsi akaderera-mutengo uye ari nyore kugadzirisa uye kushanda. Panguva imwecheteyo, vanowedzera kushandiswa kwesimba re data data uye zvakaoma kuyera. Masisitimu akadaro ari nyore uye anoshanda apo hunyanzvi diki hunodiwa uye kuwedzera kwavo kusingatarisirwe.
Modular UPSs inoratidzirwa nekureruka scalability, kushoma kupora nguva, kuvimbika kwepamusoro uye kuwanikwa. Masisitimu akadaro akanakira kuwedzera data center huwandu kune chero nhanho pamutengo wakaderera.
