Kuchokera kumaphunziro afizikiki tikudziwa kuti mota yamagetsi imathanso kugwira ntchito ngati jenereta; izi zimagwiritsidwa ntchito kubweza magetsi. Ngati tili ndi chinthu chachikulu choyendetsedwa ndi mota yamagetsi, ndiye kuti tikamabowola, mphamvu yamakina imatha kusinthidwa kukhala mphamvu yamagetsi ndikubwezeretsedwanso mudongosolo. Njirayi imagwiritsidwa ntchito mwakhama m'makampani ndi zoyendera: imachepetsa mphamvu zamagetsi, koma sizigwirizana bwino ndi magetsi osasunthika. M'machitidwe ochiritsira ayenera kugwiritsidwa ntchito mosamala kwambiri.
Kodi kusinthika kumakumana liti ndi UPS?
Vuto limabwera ndi mitundu ina ya katundu wamafakitale, nthawi zambiri izi ndi zida zamakina kapena zida zina zoyendetsedwa ndi makina. Amayendetsedwa ndi otchedwa ma frequency converters kapena ma servos, omwe amakhalanso osintha pafupipafupi ndi mayankho. Pamene injini ya unsembe wotero si kuperekedwanso ndi mphamvu, akhoza kusintha kwa mode jenereta, kuyamba kupanga magetsi pa braking ndi kupereka kwa maukonde athandizira.
Makhazikitsidwe amakono opanga mafakitale nthawi zambiri amatetezedwa ku kulephera kwa magetsi pogwiritsa ntchito UPS. Mwachitsanzo, tikhoza kuganizira makina CNC ntchito mkulu-mwatsatanetsatane processing wa workpieces mtengo. Kuzungulira kwaukadaulo kuyenera kumalizidwa moyenera, ndipo ngati njirayo isokonezedwa, sikungatheke kuyibwezeretsanso ndipo chogwirira ntchito chiyenera kutayidwa. Zitha kutenga ma ruble oposa miliyoni imodzi, ngati tikulankhula za umisiri wamakina, kupanga zombo ndi kupanga ndege, komanso luso lankhondo ndi mlengalenga.
Chifukwa chiyani ma UPS samagwirizana ndi kuchira?
Ma frequency converter amadutsa magetsi opangidwa ndikutulutsa kuti alowe. Pachifukwa ichi, kayendetsedwe ka kayendetsedwe ka magetsi ayenera poyamba kuganiza kuti angathe kubwezeretsa mphamvu pa intaneti kuti agwiritse ntchito mopindulitsa. Dongosolo loterolo limawerengedwa mosamala ndipo limawononga ndalama zambiri, koma limakupatsani mwayi wochepetsera mphamvu zamagetsi ndikupewa ngozi. Ngati makhazikitsidwe angapo otetezedwa ndi UPS agwira ntchito nthawi imodzi, mphamvu yopangidwa ndi imodzi mwazo imatha kudyedwa ndi oyandikana nawo. Ngati pali mavuto ndi kasamalidwe ka katundu ndi kuwerengera, kapena gawo limodzi lokha lomwe likugwira ntchito mudongosolo, kuchira kudzakhudza UPS. Zipangizo zomwe zimamangidwa molingana ndi dongosolo lachikale sizimapangidwira izi: mphamvu imadutsa pa inverter, yomwe imayamba kugwira ntchito ngati yowonjezera, yomwe imayambitsa kuwonjezeka kwa magetsi pa basi ya DC. Pafupifupi palibe UPS yamakono yomwe imatha kuthana ndi vutoli; chitetezo chikayambitsidwa, chimasinthira kunjira yolambalala.
Kutuluka kuli kuti?
Pofuna kupewa kuti ma frequency converter asaphulike, momwe mphamvu yopangidwa ndi kukhazikitsa pakuchira imapita mudongosolo, ma module apadera okhala ndi ma braking resistors amayikidwa. Iwo akuphatikizidwa mu dera pa nthawi yoyenera, kutaya mphamvu zowonjezera monga kutentha ndipo, kuwonjezera pa zipangizo zamakampani, zimatetezanso UPS. Vuto, tikubwereza, lathetsedwa kale pakupanga gawo laukadaulo waukadaulo: katundu ndi dongosolo loyang'anira mphamvu ziyenera kukhazikitsidwa molondola. Mutha kulumikizanso ma UPS angapo molingana ndi katundu wocheperako - pakadali pano, kuchirako "kwaphwanyidwa" ndi mphamvu ndipo sikungathenso kuletsa makina osasinthika amagetsi.
