Ni ubuhe bwoko bw'amashanyarazi ya UPS ashyirwa mu byiciro hakurikijwe ihame ry'imikorere? UPS uninterruptible power supply igabanyijemo ibice bitatu: backup, online na online interactive UPS. Imikorere y'amashanyarazi ya UPS kuva hejuru kugeza hasi ni: transformation ebyiri kuri interineti, interactive kuri interineti, ubwoko backup. Igiciro muri rusange gihuye n'imikorere. Gusobanukirwa uburyo amashanyarazi ya UPS akoreshwa bishobora gufasha kurinda neza umuriro wa UPS mu kubungabunga buri munsi.
Ni ubuhe bwoko bw'amashanyarazi ya UPS bushyirwa mu byiciro hakurikijwe ihame ry'imikorere?
Ingufu za UPS nizo dukunze kwita UPS uninterruptible power supply. Ingufu za UPS zikora mu buryo butatu bukurikira:
1. Ingufu za UPS zitangwa mu buryo butaziguye zivuye ku muyoboro w’amashanyarazi zijya ku mutwaro iyo umuyoboro w’amashanyarazi usanzwe. Iyo umuyoboro w’amashanyarazi urenze ubushobozi bwawo bwo gukora cyangwa umuriro ubuze, umuriro uhinduka ujya ku muyoboro w’amashanyarazi ukoresheje batiri binyuze mu gusimbuza. Urangwa n’imiterere yoroshye, ingano nto n’igiciro gito, ariko urwego rw’amashanyarazi yinjira ni ruto, ingufu zisohoka zirahamye kandi ubuziranenge ni bubi, hari igihe cyo guhinduranya, kandi imiterere y’umuyoboro w’amashanyarazi muri rusange ni kare.
Ingufu za UPS zitangwa na sine wave zisubirwamo: umusaruro w'imashini ushobora kuba 0.25KW ~ 2KW. Iyo ingufu z'amashanyarazi zihindutse hagati ya 170V ~ 264V, UPS irenga 170V ~ 264V.
2. Ingufu za UPS zikoreshwa kuri interineti zitangwa mu buryo butaziguye kuva ku muyoboro w’amashanyarazi kugera ku mutwaro iyo umuyoboro w’amashanyarazi ari muzima cyangwa hejuru, umurongo ugenzura amashanyarazi imbere wa UPS urasohoka. Iyo umuriro wa UPS udasanzwe cyangwa ukabura umuriro, umuriro uhinduka inverter ya batiri binyuze mu ihinduranya. Urangwa n'uruhererekane rwagutse rw'amashanyarazi yinjira, urusaku ruto, ingano nto n'ibindi biranga, ariko hari n'igihe cyo guhinduranya.
Ingufu za UPS zikorana kuri interineti zifite ubushobozi bwo kuyungurura, ubushobozi bukomeye bwo kurwanya impanuka mu mujyi, igihe cyo guhindura amakuru kiri munsi ya 4ms, kandi umusaruro wa inverter ni analog sine wave, bityo ushobora gushyirwamo seriveri, routers n'ibindi bikoresho bya network, cyangwa ugakoreshwa mu bice bifite amashanyarazi akomeye.
3. Ingufu za UPS zo kuri interineti, iyo amashanyarazi ari asanzwe, amashanyarazi atanga voltage ya DC kuri inverter ku mutwaro; iyo amashanyarazi atari asanzwe, inverter ikoreshwa na bateri, kandi inverter ihora ikora kugira ngo ibone umusaruro uhoraho. Irangwa n'uruhererekane rwagutse cyane rw'amashanyarazi yinjira, muri rusange nta guhindagurika kw'igihe n'amashanyarazi asohoka kandi ifite ubunyangamugayo bwinshi, cyane cyane ikwiriye ingufu nyinshi, ariko igiciro ni kinini. Kuri ubu, amashanyarazi ya UPS afite ingufu zirenze 3 KVA hafi ya yose ni amashanyarazi ya UPS yo kuri interineti.
Imiterere y'amashanyarazi ya UPS kuri interineti iragoye, ariko ifite imikorere myiza kandi ishobora gukemura ibibazo byose by'amashanyarazi, nka PS series y'inzira enye, ishobora gusohora AC y'umuraba wa sine uhoraho nta guhagarara, kandi igakemura ibibazo byose by'amashanyarazi nko kwiyongera, kwiyongera, guhindagurika kw'amashanyarazi; bisaba ishoramari rinini, ikoreshwa mu bidukikije bikomeye by'amashanyarazi y'ibikoresho by'ingenzi n'aho bikorera.
Uburyo bune bwo gukora UPS UPS
Bitewe n'uko ikoreshwa rihagaze, umuriro wa UPS udashobora guhindagurika ushobora guhindurwamo uburyo bune butandukanye bwo gukora: uburyo busanzwe bwo gukora, uburyo bwo gukora bateri, uburyo bwo gukora bypass na uburyo bwo kubungabunga bypass.
1. imikorere isanzwe
Mu bihe bisanzwe, ihame ry’ingufu za sisitemu y’amashanyarazi ya UPS idahinduka ni uguhindura ingufu za AC zinjira mu muyoboro w’amashanyarazi mu gihe umujyi usanzwe, hanyuma ugashyira umuriro mu ikoreshwa ry’ingufu mu guhagarara; bikwiye gushimangirwa ko sisitemu y’amashanyarazi ya UPS idakora iyo umuriro ubuze, niba voltage iri hasi cyane cyangwa hejuru cyane, habayeho guturika ako kanya kugira ngo bigira ingaruka ku mikorere isanzwe y’ibikoresho, sisitemu ya UPS iba ikora neza kugira ngo itange umuriro uhamye kandi usukuye ku bikoresho bitwara imizigo.
2. Igikorwa cyo kunyura mu nzira
Iyo ingufu z'amashanyarazi ari zisanzwe, iyo ingufu za UPS zigaragara nk'izirenze urugero, itegeko ryo kunyura mu buryo bw'intoki cyangwa imashini ikoresha ikoranabuhanga (bypt command) cyangwa imashini ikora nabi, inverter ishyushye cyane cyangwa imashini inaniwe gukora neza, ingufu za UPS muri rusange zihindura umusaruro wa inverter kugira ngo zinyura mu buryo bw'ikoranabuhanga, ni ukuvuga, zitangwa n'amashanyarazi. Kubera ko ingano y'amashanyarazi ya UPS igomba kuba imwe n'ingano y'amashanyarazi mu gihe cyo kunyura mu buryo bw'ikoranabuhanga (bypass), ikoranabuhanga ryo guhuza ingufu za phase lock rikoreshwa kugira ngo rimenye neza ko ingufu za UPS zihuzwa n'ingano y'amashanyarazi.
3. Gutunganya inzira yo kunyuramo
Iyo amashanyarazi yihutirwa ya UPS asanwe, gushyiraho inzira yo kunyuramo intoki bitanga ingufu zisanzwe ku bikoresho bitwara imizigo. Iyo imirimo yo kubungabunga irangiye, amashanyarazi ya UPS atangira kongera gukoreshwa, maze amashanyarazi ya UPS agahinduka imikorere isanzwe.
4. bateri yo gusiga inyuma
Iyo umuriro w’amashanyarazi udasanzwe, UPS izahindura umuriro w’amashanyarazi ubitse muri batiri ukajya mu muyoboro usimburana. Muri iki gihe, inverter izashyirwamo na batiri, kandi inverter izakomeza gutanga ingufu no gutanga umutwaro wo gukomeza gukoresha kugira ngo igere ku musaruro w’amashanyarazi uhoraho.
Hejuru hari uburyo UPS ishyira mu byiciro amashanyarazi adashobora gucika intege, UPS ni igikoresho cyihariye gitanga ingufu gikoreshwa mu kurinda umutekano w'ibikoresho by'ikoranabuhanga. Iyo amashanyarazi akora neza, ashobora kugira uruhare mu gutuma ingufu zihagarara, kugira ngo amashanyarazi abe meza, iyo amashanyarazi aciwe, habayeho impanuka y'umuriro, ishobora guhindura ingufu z'amashanyarazi za mbere mu gaciro gasanzwe k'amashanyarazi kugira ngo itange amashanyarazi yihutirwa.
