• Vanoshandisa II chikamu, iyo inosanganisira ruzhinji rwevaroja venzvimbo yekutengesa, havana hukama kune yakavimbiswa magetsi kubva kune dhiziri jenareta seti uye vanogona kuvimba chete neguta remagetsi grid uye yavo (yemunharaunda) isingapindiki magetsi emagetsi (UPS).
• Vanoshandisa Category I otomatiki chinja kune jenareta redhiziri rakaiswa pakaitika njodzi pamagetsi emagetsi eguta, asi kusvika dhiziri seti yatangwa, ivo vanozodzima-simba. Kune ava maroja, kudzimwa kwemagetsi kwakakosha kune bhizinesi kana kuchengetedzwa kweveruzhinji. Munzvimbo yezvitoro, maroja akadaro anowanzo sanganisira ma pharmacy ane mafiriji emishonga, mahofisi ekurapa nemazino, uye nzvimbo dzekutandarira dzevana.
• Vanoshandisa Ini inokosha chikamu gamuchira isina kukanganiswa magetsi uye haigone kudzimwa kunyangwe kwenguva pfupi. Kune vatengi vakadai, zvitubu zvitatu zvemagetsi zvinoshandiswa - chiteshi cheguta uye dhiziri jenareta seti, uye panguva yekutanga kweiyo dizeli generator seti ivo vanopihwa simba kubva kumaindasitiri UPSs. Vatengi vakadaro vanosanganisira aramu yemoto uye otomatiki yekudzima moto masisitimu, kudzivirira kwevanhu uye masisitimu ekuyeverwa kwekukurumidzira, kuvhenekesa kwechimbichimbi, nzvimbo uye midziyo yenzvimbo yekutengesa yekutumira service. Kana makambani eIT achirenda nzvimbo munzvimbo yekutenga, ivo zvakare vanoodha isina kukanganiswa magetsi ivo pachavo.

Iko kushandiswa kweindasitiri UPS munzvimbo dzekutenga kune yakakosha chikamu chevatengi kunoitwa zvinoenderana nepakati chirongwa. Muchirongwa ichi, magetsi anopihwa kubva kune imwe sosi kune vese vatengi vechikamu ichi mukati menzvimbo yekutengesa.

Kune varojawo zvavo vepanzvimbo yekutenga - zvitoro, macafe, magym, salons, nezvimwewo, kupa magetsi epakati akavimbiswa kana asina kukanganiswa magetsi anogona kudhura zvakanyanya sarudzo. Mumamiriro ezvinhu akadaro, zvinokwanisika nehupfumi kushandisa iyo inonzi decentralized uninterruptible power supply scheme, iyo ichakurukurwa pasi apa.

Decentralized UPS scheme - zvakanakira uye zvisingabatsiri

Decentralized and centralized uninterruptible power supply schemes hazvina kupindirana. Aya mazano maviri anogona uye anofanira kubatanidzwa. Semuyenzaniso, vatengi vakakosha (pamwe nevaya vakabhadhara chaizvo) mukati menzvimbo yekutengesa vanodzivirirwa nemaindasitiri makuru eUPS, asi muchitoro chakasarudzika chisina simba rakavimbiswa, yekupinda-level uye yepakati-renji UPS inogona kushandiswa munharaunda kupa dziviriro. zvemarejista emari, maseva, maprinta, nezvimwewo tekinoroji.

Ngatitarisei zvakanakira nekuipira kweiyo decentralized magetsi emagetsi chirongwa uye, chekutanga, nezve zvakanakira kushandisa emuno UPSs:

• hapana wiring itsva inodiwa, madziro emadziro aripo anoshandiswa; maUPS emuno ari nyore kuisa mukushanda uye kubatanidza kune marejista emari, makomputa, uye zvimwe zvakakosha midziyo; pakuchinja nzvimbo dzakarenda, maUPS akadaro anotorwa pamwe chete nawo uye anoiswa munzvimbo itsva;
• yenzvimbo yekupinda-level uye yepakati-kirasi UPS ine mutengo wakaderera - bhajeti rechero bhizinesi diki rinogona kutenga maUPS akadaro - uye simba rinosvika 3000 VA rinokutendera kuti ubatanidze akati wandei marejista emari kana maPC kune imwe UPS;
• muroja haana kusungirirwa pamwero wemutoro wakagoverwa, kuchinja kwenhamba yemabhuku emari kana zvimwe zvigadzirwa nekuda kwekuwedzera kwebhizimisi hazvizodi kubvumirwa kutsva kwechibvumirano chekugovera magetsi;
• kana muroja atove neseti yeUPS yavo, zvine musoro kuvashandisa muhurongwa hwemagetsi husingapindike.

Dzimwe nguva manejimendi enzvimbo yekutenga - kunyanya kana paine mukana wemahara mushure mekunge muroja kiyi abuda - anotanga kuramba achipa maroja kuti abatanidze kunetiweki yemagetsi akavimbiswa kana asina kukanganiswa kana magetsi akadzimwa kubva muchiteshi cheguta.

Apa ndipo pazvinenge zviri nani kushandisa centralized uninterruptible power supply:

• kuenderera mberi kwebhizinesi kwakakosha kumuroja (semuenzaniso, ma pharmacy ane mafiriji makabhati emishonga, mahofisi ekurapa nemazino, makiriniki erunako ane maitiro anoramba achitenderera, maroja anopa masevhisi epamhepo, semakambani eIT): magetsi epakati asingapindirwe akagadzirirwa kuwanikwa kusingagumi. vatengi venguva (zvichienderana nekupihwa kwemafuta ejenareta seti), uye UPS yemuno inogona kutsigira kushanda kwemidziyo kwenguva pfupi, kazhinji isingasviki 15-20 maminetsi, uye kana magetsi asina kudzorerwa panguva. panguva ino, midziyo icharamba ichidzimwa;
• kana nhamba yeUPS yemuno ichipfuura gumi nemaviri, uye ari emhando dzakasiyana uye akatengwa panguva dzakasiyana, ipapo kutarisa mamiriro emabhatiri nekuatsiva kunova kukanganisa kunoonekwa, zvinova nyore kusaona bhatiri rakatove rakashata, uye se mhedzisiro, iyo UPS haizokwanisa kuchengetedza midziyo kana paine kutadza kwemagetsi;
• Kana magetsi akadzimwa, maaramu akawanda anonzwika kubva kuUPS emuno anogona kukonzera kushatirwa uye kunetseka kune vashanyi (semuenzaniso, vatengi mumakiriniki erunako).

Inotevera - nezve mhando uye mhando dzeUPS dzakanyatsokodzera nzvimbo yekutengesa maroja kubva pakati pemabhizinesi madiki.

Kurudziro pamhando uye simba reUPS rekutenga nzvimbo dzemaroja

Nyaya yemhando nhatu dzeUPS - offline UPS, line-interactive type uye online UPS - inogona kuwanikwa mune dzinenge chinyorwa chega chega chenyaya iyi, asi haugone kuita pasina iyo kana iwe ukapa zano rekusarudza isinga vhiringike magetsi.

Izvo zviri nyore uye zvakachipa backup UPS (offline, back-UPS, stand-by) muzviitiko zvakawanda hazvikurudzirwi nekuda kwekuti magetsi anopiwa kubva kunetiweki anoshandiswa zvakananga kumutoro. Kunyangwe iyo voltage mune backup UPSs yakasefa, haina kudzorwa neimwe nzira - kana paine yakaderera kana yakakwira voltage munetiweki, saka izvi ndizvo chaizvo zvichapihwa kumutoro.

Simba rebhatiri mune backup UPSs rinobatidzwa chete kana paine kurasikirwa kwakakwana kwevoltage painopinza, uye inenge (inenge) fomu yevoltage sine wave inopihwa kune inobuda, iyo ine mhedzisiro yakaipa pakushanda kwemidziyo ine. magetsi emagetsi emagetsi emagetsi, mota dzemagetsi, chokes, Hi-Fi odhiyo nemavhidhiyo midziyo, mabhailer ekudziya ane pombi dzinotenderera, mafiriji uye maairconditioner, pombi dzemvura. Izvo hazvikurudzirwe kushandisa backup UPSs kuchengetedza michina yemurabhoritari uye michina yekurapa, iyo inogona chete kufambiswa nevoltage ine yakanaka sinusoid.

Mutsara-inopindirana UPS (line-interactive) - inonyanya kushanda maererano nemutengo / hutano hwehuwandu hwemagetsi. Musiyano wakakosha pakati pemutsara-inopindirana UPS uye isina online UPS kuvepo kwevoltage stabilizer (inonziwo autotransformer, AVR, Automatic Voltage Regulator). Naizvozvo, mutsara-inopindirana UPS inonyanya kubatsira kana ichishandiswa munzvimbo umo magetsi ekuisa anogona kusiyana zvakanyanya. Iko magetsi ekudzikamisa masimba eUPS akadaro akakosha - kubva 150-160 V kusvika 270-290 V pakuiswa, zvichienderana nemuenzaniso, nepo kubuda kuchave kwakagadzikana 230 V. Mazuva ano mutsara-interactive UPSs, akadai Eaton 5P uye 5PX yakatevedzana, ine microprocessor control uye inopa yakanakira sine wave yeinobuda voltage.

Online UPS (pamhepo, kutendeuka kaviri) - yakanyatsopesana neiyo isina UPS maererano nemhando yemagetsi: zvisinei nevolti kana kupindira mumagetsi, yakanakira sine wave ichapihwa kumutoro. Shanduko yakapetwa kaviri inoitwa mukati meUPS - iyo alternating yekupinda voltage inoshandurwa kuita yakananga voltage, uyezve ichichinjanisa voltage, ine yakanaka paramita. Izvo chete zvakashata zvepamhepo UPS mutengo wakakwira.

Eaton inokurudzira mamodheru anotevera emutsara-inopindirana UPS kune vatengesi vepanzvimbo yekutenga:

• Kana mudziyo wakachengetedzwa wakashongedzerwa tambo yekubatanidza kune yakajairwa kutenderera Euro socket (DIN Socket Type-F), ipapo unogona kusarudza mutsara-inopindirana UPS modhi Eaton Ellipse ECO (simba kubva ku500 VA kusvika 1600 VA) kana Eaton Ellipse PRO. (simba kubva ku650 VA kusvika 1600 VA) - imwe neimwe UPS ine kubva kune ina kusvika kumasere ekubuda, iyo inopinza voltage inogona kuva muhuwandu hwe161-284 V;
