Kubva pakosi yefizikisi isu tinoziva kuti mota yemagetsi inogona zvakare kushanda sejenareta; iyi mhedzisiro inoshandiswa kudzoreredza magetsi. Kana isu tiine chimwe chinhu chakakura chinotyairwa nemota yemagetsi, saka kana ichibhureki, simba remakanika rinogona kushandurwa kudzoka kuita simba remagetsi rodzoserwa muhurongwa. Iyi nzira inoshandiswa zvakanyanya mumaindasitiri uye kutakura: inoderedza kushandiswa kwesimba, asi haina kunyatsoenderana nemagetsi asingagoneki. Muchirongwa chekudzorera vanofanira kushandiswa nekuchenjerera kukuru.
Kuzvarwa patsva kunosangana riini neUPS?
Dambudziko rinomuka nemamwe marudzi emitoro yemaindasitiri, kazhinji aya mamwe emhando yematurusi emuchina kana zvimwe zvinofambiswa nemichina. Iwo anodzorwa neanonzi ma frequency converters kana servos, ayo ariwo ma frequency converters ane mhinduro. Kana iyo injini yekuisa kwakadaro isingachapihwe simba, inogona kushandura kune jenareta modhi, tanga kugadzira magetsi panguva yebhureki uye kugovera kune network yekupinza.
Mazuva ano maindasitiri ekuvandudza magadzirirwo anowanzo kuchengetedzwa kubva mukutadza kwemagetsi uchishandisa UPS. Semuyenzaniso, isu tinogona kufunga CNC michina inoshandiswa yakakwirira-chaiyo kugadzirwa kweanodhura workpieces. Iyo tekinoroji kutenderera kunofanirwa kupedzwa nemazvo, uye kana maitiro akavhiringidzwa, hazvigoneke kuidzosera uye workpiece ichafanirwa kuraswa. Inogona kudhura anopfuura miriyoni imwe rubles, kana tikataura nezve mechanical engineering, shipbuilding uye kugadzirwa kwendege, pamwe chete neuto uye nzvimbo teknolojia.
Sei maUPS asingaenderane nekupora?
Iyo frequency converter inopfuudza iyo inogadzirwa magetsi uye inoburitsa kune iyo yekuisa. Muchiitiko ichi, magetsi ekugadzirisa magetsi anofanira kutanga atora mukana wekudzorera simba kunetiweki kuitira kushandiswa kunobatsira. Iyi sisitimu yakanyatsoverengerwa uye inodhura zvakanyanya, asi inobvumidza iwe kuderedza mari yemagetsi uye kudzivirira njodzi. Kana akati wandei UPS-akadzivirirwa kumisikidzwa kushanda panguva imwe chete, simba rinogadzirwa neimwe yaro rinogona kupedzwa nevavakidzani. Kana paine matambudziko ane mutoro manejimendi uye kuverenga, kana imwe chete unit iri kushanda muhurongwa, kupora kuchakanganisa UPS. Zvishandiso zvakavakwa maererano neklassical scheme hazvina kugadzirirwa izvi: simba rinopfuura nepakati inverter, iyo inotanga kuita basa remhando yebooster, iyo inotungamira kuwedzera kwemagetsi paDC bhazi. Inenge pasina UPS yemazuva ano inokwanisa kunyatso kutarisana nedambudziko iri; mushure mekudzivirirwa kwatanga, inoshandura kubypass mode.
Iko kubuda kuri kupi?
Kuti udzivise iyo frequency converter kubva pakuputika, kuburikidza iyo iyo simba rinogadzirwa nekumisikidza panguva yekudzoreredza rinopinda muhurongwa, ma module akakosha ane braking resistors anoiswa. Ivo vanosanganisirwa mudunhu panguva yakakodzera, vanobvisa yakawandisa simba nenzira yekupisa uye, kuwedzera kune zvigadzirwa zveindasitiri, inodzivirirawo UPS. Dambudziko, isu tinodzokorora, rinogadziriswa nechekare padanho rekugadzira tekinoroji yakaoma: mutoro uye simba rekutonga system rinofanirwa kugadziridzwa nenzira kwayo. Iwe unogona zvakare kubatanidza akati wandei maUPS anoenderana nemutoro mudiki - mune iyi kesi, kudzoreredza "kupwanywa" nesimba uye haichakwanise kudzima iyo isingachinjiki yemagetsi system.
