Ihame ry'imikorere ry'abatangiza ibintu mu buryo bworoshye (Ibisobanuro by'umwuga ku bucuruzi bw'amahanga mu itumanaho rya tekiniki)

A intangiriro yoroshye (Icyesipanyoli: arrancador suave) ni igikoresho cyo kugenzura moteri zitwara amashanyarazi zikoresha AC, imikorere yazo y'ibanze ni kugira ngo utangire kandi uhagarare neza binyuze mu kugenzura neza ingufu z'amashanyarazi ya moteri.Irinda kwangirika kwa moteri, imiyoboro y'amashanyarazi, n'ibikoresho bitwara imizigo biterwa n'umuvuduko mwinshi w'amashanyarazi mu gihe cyo gutangiza, kandi ikoreshwa cyane muri Ibikoresho by'inganda nk'ipompo, amafeni, compressor, na conveyors.

Ihame ry'Ibikorwa ry'Ishingiro: Kugenzura Inzira y'Umuvuduko w'Ingufu (Uburyo Busanzwe)

Igice cy'ingenzi cya Itangiriro ryoroshye niTriaccyangwa module ya thyristor irwanya parallel(amatsinda abiri ya thyristors ahujwe mu buryo bunyuranyije kugira ngo agere ku buyobozi bubiri bw'imbaraga za AC). Uburyo bwo gukora bwayo bushingiye ku ihame rya "voltage gradient", hamwe n'inzira yihariye ikurikira:

1. Icyiciro cyo Gutangira:

• Iyo moteri ihujwe na Ingufu z'amashanyarazi, icyuma cyoroshye cyo gutangiza ibintu cyongera buhoro buhoro inguni y'umuyoboro (uruhererekane rw'umurimo) wa thyristor binyuze mu buryo bw'ikoranabuhanga bwo kugenzura, ku buryo voltage ikoreshwa kuri stator winding ya moteri izamuka kuva kuri 0 kugera kuri voltage igenwe (voltage rise curve irashobora gushyirwaho, nka linear cyangwa exponential).
• Torque ya moteri ingana na kare y'amashanyarazi (T∝U²). Iyo voltage izamutse buhoro buhoro, torque nayo iriyongera neza, kandi umuvuduko wa moteri ugenda wihuta kuva ku gice cyo kuruhuka kugera ku muvuduko ugenwe (ubusanzwe amasegonda 3-30, ushobora guhindurwa bitewe n'umutwaro).
• Ugereranije no gutangira mu buryo butaziguye (aho voltage ihita ishyirwa ku gaciro kagenwe, kandi umuriro utangira ushobora kugera ku nshuro 5-8 z'umuvuduko ugenwe), starter yoroshye ishobora kugabanya umuriro utangira kugeza ku nshuro 1.5-4 z'umuvuduko ugenwe, bigabanura cyane ingaruka z'umuvuduko.

2. Icyiciro cy'imikorere:

• Nyuma yuko moteri igeze ku muvuduko ugenwe, thyristor y'icyuma gitangira cyoroshye iba irimo gukora neza (bingana na short circuit), kandi moteri iba ihujwe neza n'urusobe rw'amashanyarazi kugira ngo ikore. Muri iki gihe, icyuma gitangira cyoroshye nta ngufu gikoresha, birinda gushyuha igihe kirekire.
• Amwe mu mamodeli yo mu rwego rwo hejuru afite agakoresho ko gufunga bypass. Iyo mashini imaze gutangira, agakoresho ko gufunga karaza kugira ngo gasimbuze thyristor kugira ngo ikoreshwe, birushaho kunoza ubwizerwe no kugabanya igihombo.

3. Icyiciro cyo Guhagarara:

• Nyuma yo kwakira ikimenyetso cyo guhagarara, icyuma cyoroshye gitangira gigabanya buhoro buhoro inguni yo kuyobora ya thyristor, bigatuma voltage ya moteri igabanuka buhoro buhoro, kandi umuvuduko ukagabanuka neza kugeza aho uhagaze (Guhagarara Kworoshye). Ibi birinda ingaruka z'uburemere bw'imizigo buterwa no guhagarara gutunguranye (nk'ingaruka z'amazi ku ipompo no kunyerera kw'ibikoresho by'imodoka).

Ibiranga Tekiniki by'ingenzi (Byahinduwe mu Itumanaho ry'Ibipimo by'Tekiniki by'Ubucuruzi bw'Amahanga)

1. Ingano y'ubu itangira: Mu gushyiraho umupaka ntarengwa w'amashanyarazi utangira, bibuza voltage ya grid y'amashanyarazi kugwa kandi bikarinda moteri kuzunguruka umuyoboro wayo ku muvuduko mwinshi w'amashanyarazi.
2. Guhindura umurongo w'amashanyarazi: Igihe cyo kuzamuka k'umuvuduko (amasegonda 0-30) gishobora gushyirwaho kugira ngo gihuzwe n'imiterere itandukanye y'umutwaro (urugero, igihe kirekire cyo kuzamuka kirakenewe kugira ngo imitwaro iremereye itangire).
3. Imirimo yo Kurinda: Ihuriza hamwe Uburinzi bw'umutwaro urenze urugero, kurinda igihombo cy'ingufu, kurinda umuriro urenze urugero/urenze urugero, kurinda ubushyuhe bwinshi, nibindi. Bihita bihagarika amashanyarazi n'amatangazo mu gihe habayeho amakosa.
4. Ubwoko bwa moteri bukoreshwa: Ikwiriye gusa moteri za AC zitwara amashanyarazi zifite ibyiciro bitatu (ubwoko bwa squirrel-cage), ntabwo ikwiriye moteri za DC, moteri zihuza amashanyarazi, cyangwa moteri zizunguruka.
5. Itandukaniro na Inverters (VFD)(Ikibazo cy’inshuro nyinshi mu itumanaho ry’ubucuruzi bw’amahanga):

Ingero zisanzwe z'ikoreshwa (zijyanye n'itumanaho ry'ubucuruzi bw'amahanga)

• Pompe/Abafana: Irinde ihindagurika ry'umuyoboro w'amashanyarazi riterwa n'ingaruka z'umuriro utangiye, kandi ugabanye ingaruka z'amazi ku nyundo/ingaruka z'umuyaga mu gihe cyo guhagarara;
• Compressors/Air Compressors: Kugabanya umutwaro wa mekanike mu gihe cyo gutangiza no kurinda ibice nka silindiri na pistons;
• Ibikoresho bitwara abantu: Birinda ko ibikoresho binyerera mu gihe cyo gutangira no gukumira feri neza mu gihe cyo guhagarara;
• Ibikoresho by'imashini/Imitwaro y'ipompe: Bikwiriye imashini rusange zidasaba kugenzura umuvuduko ariko zishobora kwitabwaho n'ingaruka z'itangizwa.

Niba ukeneye guhindura ibipimo bya tekiniki byihariye (nk'urugero rw'amashanyarazi, igipimo cy'ubushyuhe, cyangwa uburyo bwo kugenzura bwa moderi runaka y'ibikoresho byoroshye) mu itumanaho ry'ubucuruzi bw'amahanga (urugero, guhindura kuri imeri, gusobanura ibipimo), nyamuneka tanga ibikubiye muri ibyo bipimo kugira ngo ubone ubufasha bwiyongereye!
