Kuki moteri ikora umuvuduko w'amashanyarazi?

Kuki moteri ikora umuvuduko w'amashanyarazi?

Umuriro uri mu gice cy’intebe n’ishingiro cy’intebe ya moteri witwa umuriro w’umuriro.

Impamvu zitera umuyoboro w'amazi mu gice cy'umuyoboro:

Kudahuza kw'imbaraga za rukuruzi;

Hari harmonics mu muyoboro w'amashanyarazi;

Inganda n'imitangire mibi, bigatuma habaho icyuho cy'umwuka kidahuye bitewe n'uburyo rotator ikora;

Hari icyuho kiri hagati y'imizingo ibiri y'igice cy'ingenzi cya stator gishobora gukurwaho;

Umubare w'ibice by'inkingi ya stator byakozwe n'ibice byo gukusanya ntabwo ukwiye.

Ingaruka: Ubuso bw'umuvuduko wa moteri cyangwa imipira bizasenyuka kandi hakavuka uduce duto tumeze nk'uduce, ibyo bikazarushaho gukora neza, bikongera ubushyuhe n'ihindagurika ry'imitsi, kandi amaherezo bigatuma umuvuduko ushira.

Kuki moteri rusange zidashobora gukoreshwa mu turere twa plateau?

Ubutumburuke bugira ingaruka mbi ku kwiyongera k'ubushyuhe bwa moteri, corona ya moteri (moteri ifite amashanyarazi menshi) no kugabanuka kwa moteri ya DC.

Ingingo eshatu zikurikira zigomba kwitabwaho:

Uko uburebure burushaho kuba bwinshi, ni ko ubushyuhe bwa moteri burushaho kwiyongera kandi imbaraga zo gusohora zigabanuka. Ariko, iyo ubushyuhe bugabanutse hamwe n’ubwiyongere bw’ubutumburuke buhagije kugira ngo bwishyure ingaruka z’ubutumburuke ku kwiyongera k’ubushyuhe, imbaraga z’umusaruro za moteri zishobora kugumaho zidahinduka;

Ingamba zo kwirinda Corona zigomba gufatwa iyo moteri zifite ingufu nyinshi zikoreshwa ku misozi miremire;

Ubutumburuke si bwiza ku guhindura moteri za DC, bityo hakwiye kwitabwaho guhitamo ibikoresho bya karuboni.

Kuki moteri idakwiye gukoreshwa n'umutwaro woroheje?

Iyo moteri ikora ifite umutwaro muto, bizatera:

Ingufu za moteri ni nkeya;

Ubushobozi bwa moteri buri hasi.

Iyo moteri ikora ifite umutwaro muto, bizatera:

Ingufu za moteri ni nkeya;

Ubushobozi bwa moteri buri hasi.

Bizatera gusesagura ibikoresho no kudakoresha amafaranga menshi.

Ni izihe mpamvu zitera gushyuha cyane kwa moteri?

Umutwaro ni munini cyane;

icyiciro cyo kubura;

Imiyoboro y'umwuka irafunze;

Igihe cyo gukoresha umuvuduko muto ni kirekire cyane;

Ibyuma bihuza amashanyarazi ni binini cyane.

Ni iyihe mirimo igomba gukorwa mbere yo gushyiramo moteri imaze igihe kinini idakoreshwa?

Pima stator, uburyo bwo kwirinda gushyushya hagati y’ingazi n’ingazi ndetse n’uburyo bwo kwirinda gushyushya hagati y’ingazi n’ingazi.

Ubudahangarwa bw'ubushyuhe R bugomba kuba bwujuje ibi bikurikira:

R＞Un/(1000+P/1000)(MΩ)

Un: voltage ifite ingano y'izunguruka rya moteri (V)

P: Ingufu za moteri (KW)

Kuri moteri ya Un=380V, R＞0.38MΩ.

Niba ubushobozi bwo gukingira ubwikorezi buri hasi, ushobora:

a: Moteri ikora amasaha 2 kugeza kuri 3 idakoresha umutwaro kugira ngo yumuke;

b: Koresha umuyoboro muto w’amashanyarazi uhindagurika wa 10% by’amashanyarazi agenwe kugira ngo unyure mu muyoboro cyangwa uhuze imiyoboro y’ibyiciro bitatu mu buryo bukurikiranye hanyuma utekeshe umuyoboro utaziguye kugira ngo umuyoboro ugume kuri 50% by’amashanyarazi agenwe;

c: Koresha umuyaga wohereza umwuka ushyushye cyangwa ikintu gishyushya kugira ngo gishyushye.

Sukura moteri.

Simbuza amavuta yo guterura.

Kuki ntashobora gutangiza moteri ahantu hakonje uko nshaka?

Iyo moteri igumye ahantu hari ubushyuhe buke igihe kirekire cyane, iza:

Ubwishingizi bw'imodoka bwacitse;

Amavuta yo mu bwoko bwa bearing arakonjesha;

Ifu yo gusoda ku migozi.

Bityo rero, moteri igomba gushyushya no kubikwa ahantu hakonje, kandi imiyoboro n'ibice by'amashanyarazi bigomba kugenzurwa mbere yo gukora.

Ni izihe mpamvu zitera imihindagurikire y'amashanyarazi y'ibice bitatu muri moteri?

Kudahuza kwa voltage mu byiciro bitatu;

Ishami runaka ry’icyiciro imbere muri moteri rifite ubusudi bubi cyangwa ridakorana neza;

Moteri izunguruka ihindura uruziga rugufi cyangwa uruziga rugufi rujya hasi cyangwa urwego rujya ku rundi;

Ikosa ryo gukoresha insinga.

Kuki moteri ya 60Hz idashobora guhuzwa n'amashanyarazi ya 50Hz?

Mu gushushanya moteri, urupapuro rw'icyuma rwa silikoni muri rusange rukorwa mu gace k'ubushyuhe bw'umuyoboro wa magnetization. Iyo voltage y'amashanyarazi ihoraho, kugabanya frequency byongera flux ya magnetic n'umuyoboro w'amashanyarazi, bigatuma umuyoboro wa moteri wiyongera ndetse n'umurimbo utakaza, ibyo bigatuma ubushyuhe bwa moteri bwiyongera. Mu bihe bikomeye, moteri ishobora gutwikwa bitewe no gushyuha cyane kwa coil.

Ni izihe mpamvu zitera kubura k'urwego rw'imikorere y'umubiri (motor phase)?
Ingufu:

Guhuza nabi switch;

Transformateur cyangwa umurongo ucika;

Fuse yaturitse.

Ibiranga moteri:

Utugozi turi mu gasanduku k'aho moteri ihurira turarekuye kandi aho ihurira ni habi;

Gusudira insinga z'imbere nabi;

Ingufu za moteri zacitse.

Ni izihe mpamvu zitera kuzungagurika kudasanzwe no kumva ijwi rya moteri?
Ibijyanye na tekiniki:
Gusiga amavuta make ku gikoresho cy'ubwikorezi no kwangirika kw'igikoresho cy'ubwikorezi;
Utwuma two gufatanya turarekuye;
Hari imyanda iri imbere muri moteri.
Ibice by'amashanyarazi:
Gukoresha moteri nyinshi cyane;
Ubusumbane bw'umuvuduko w'amazi mu byiciro bitatu;
icyiciro cyo kubura;
Ikosa rya "short circuit" riba mu mizunguruko ya stator na rotor;
Igice cyo gusudira cy'icyuma gifunganye kiba gifunguye kandi gitera imigozi yacitse.
Ni akazi akahe gakwiye gukorwa mbere yo gutangiza moteri?

Pima ubushobozi bwo gukingira insulation (kuri moteri zifite voltage nkeya, ntibigomba kuba munsi ya 0.5MΩ);

Pima voltage y'amashanyarazi. Genzura niba insinga za moteri ari nziza kandi niba voltage y'amashanyarazi yujuje ibisabwa;

Reba niba ibikoresho byo gutangiza imikino biri mu buryo bwiza;

Reba niba firigo ikwiriye;

Reba niba moteri ifite ifatizo kandi niba nta ihuriro ririmo;

Reba neza niba hari inenge ziri mu ihererekanya ry'amakuru;

Reba niba ahantu hafite moteri hakwiriye kandi ukureho ibikoresho bishobora gushya n'indi myanda.

Ni izihe mpamvu zitera ubushyuhe bwinshi bw'imodoka?

Moteri ubwayo:

Impeta z'imbere n'inyuma z'icyuma gifata imizigo zirakomeye cyane;

Hari ibibazo byo kwihanganira imiterere n'aho ibice biherereye, nko kuba ibice nk'imashini ikora, igifuniko cyo ku mpera, n'umugozi utoroshye;

Guhitamo nabi imiyoboro y'amashanyarazi;

Ingufu ziba zasizwe amavuta make cyangwa ingufu ntizogejwe neza, kandi hari imyanda mu mavuta;

umuyoboro w'amashanyarazi.

Ikoreshwa:

Gushyiramo icyuma nabi, nko kuba icyuma gifata moteri n'igikoresho gikoresha igikoresho kidakora neza, ntibihuye n'ibisabwa;

Umupira ukururwa cyane;

Ibyuma ntibifatwa neza, amavuta ntahagije cyangwa igihe cyo gukora cyararangiye, kandi ibyuma birakama bikangirika.

Ni izihe mpamvu zituma habaho kudakora neza kw'ibikoresho byo mu bwoko bwa moteri?

Inzira yo kuzunguruka iba itose cyangwa ifite amazi yinjira;

Ivumbi cyangwa amavuta byirundanya ku mizunguruko;

Gusaza kw'ibikoresho byo gukingira;

Ubwikorezi bw'icyuma gikingira umuriro cyangwa icyuma gikingira umuriro cyangiritse.
