Ese nkeneye igikoresho gihindura imikorere y'amajwi?

Imashini ihindura frequency – cyangwa ihindura frequency drive (VFD) – ni igikoresho cy'amashanyarazi gihindura amashanyarazi afite frequency imwe akayashyira ku yindi frequency. Ubusanzwe voltage iba imwe mbere na nyuma yo guhindura frequency. Imashini zihindura frequency zikoreshwa mu kugenzura umuvuduko wa moteri zikoreshwa mu gutwara pompe na fans.

Urugero rukurikira rugaragaza uburyo ibi bikora:
Umufana uhabwa umuvuduko wa 400 VAC, 50 Hz. Kuri iyi frequence (50 Hz), umufana ashobora gukora ku muvuduko runaka. Kugira ngo umufana akore vuba, hakoreshwa frequence converter kugira ngo yongere frequence (urugero) kuri 70 Hz. Ubundi buryo, frequence ishobora guhindurwa kuri 40 Hz niba umufana ashaka gukora buhoro.
Ntushaka gushyira ibikoresho mu isoko ry'amashanyarazi ritari ryo cyangwa ngo ube ufite ibyago byo kureka umwotsi ugasohoka mu bikoresho byawe. Kandi umwotsi uba umeze nk'"igihangange kiri mu icupa", iyo kivuye mu gikoresho cy'ikoranabuhanga, ntushobora kugisubizamo… Ibikoresho binini kandi bifite ibyiciro bitatu ntibishobora gukora ku murongo utari wo kuko umurongo utari wo ushobora kwangiza cyangwa kwangirika imburagihe ku bikoresho.
Bityo rero, uburyo bwo gutandukanya imashini ihindura frequency nyayo ikoreshwa ku mashini yoza imodoka izaba ari yo ntego nyamukuru.
Mu by’ukuri, hafi y’abacuruzi bavuga ko bafite icyuma gihindura ikirere (converter) kandi bagishyira ku mashini yoza imodoka. Ariko si igikoresho nyacyo gihindura ikirere gishobora guhindura umuvuduko w’amashanyarazi n’umuvuduko w’imashini yoza imodoka. Ubusanzwe, ni moteri nto ya 0.4 ishyirwa ku mubiri ugenda, kandi ntishobora gushyiraho ubwoko butandukanye bw’amazi asukamo umuvuduko mwinshi n’umuvuduko muto w’abafana. Ikiruta byose, iyo atari igikoresho gihindura ikirere, iyo mashini itangiye gukora, umuvuduko w’amashanyarazi uhita ukubye inshuro 6-7 kurusha umuvuduko rusange, byoroshye gutuma circus yangirika kandi amashanyarazi agapfa ubusa.
Imashini yoza imodoka ya CBK ikoresha ikoranabuhanga rya 18.5kw rihindura imikorere yayo, kandi bitewe n'umuvuduko mwinshi n'uciriritse w'amazi akoreshwa hamwe n'umuvuduko mwinshi n'uciriritse w'abafana, amashanyarazi azagabanukaho ibirenze 15%, bivuze ko nyirayo ashobora gushyiraho uburyo ubwo aribwo bwose ashaka. Kubwibyo, imashini yoza imodoka ya CBK ishobora kugabanya ikiguzi cyo kuyisana n'ikiguzi cyayo.
Ubusanzwe, ikintu cyose gifite moteri kizakenera igikoresho gihindura imikorere y’imodoka, kandi imashini imesa imodoka ya CBK irashobora kubikora.
