Ukuguqulwa kwemvamisa kanye nokusebenza kokulawulwa kwesivinini kwenjini kancane kancane kube uphawu lwezikhathi. Ukulawulwa kwesivinini se-synchronous motor ukuguqulwa kwemvamisa kanye nokulawulwa kwesivinini sokulawulwa kwemishini yokulayisha i-torque yesikwele efana nefeni kanye nepompo eqhutshwa ukuguqulwa kwemvamisa kanye nokulawulwa kwejubane kwemoto ye-AC ohlelweni lokukhiqiza. Ukulawulwa kokulawula isivinini sokuguqulwa kwemvamisa kungathola umphumela wenqubo ongcono kakhulu kanye nomphumela omkhulu wokonga nokunciphisa ukusetshenziswa.

amandla okonga umphumela

Imishini engumshini eshayelwa injini yendabuko ye-brushless excitation synchronous, efana namafeni, amaphampu, nama-compressor, isebenza ngaphansi kwefrikhwensi yamandla futhi ukuphuma kwamandla kuhlala njalo. Lapho inqubo ilungisa ukugeleza nokucindezela kwayo, izodala ukumosheka okukhulu kwamandla. Ngenxa yokuthi umthwalo uyashintsha, izinga lokugeleza lilingana nesivinini, futhi amandla adingekayo alingana nekhiyubhu yejubane. Ngakho-ke, uma izinga lokugeleza elidingekayo lingu-80% wezinga lokugeleza elilinganiselwe, kulesi simo esingokoqobo, ukusetshenziswa kokulawula okuzenzakalelayo kokulawulwa kwesivinini sokuguqulwa kwemvamisa kungasindisa ngaphezu kuka-45% wamandla kagesi kunendlela yokulawula evamile.

Ukulawulwa kwenqubo yokusebenza kokuguqulwa kwemvamisa

Umsebenzi wokulawula isivinini sokuguqulwa kwemvamisa kuwuhlelo lokulawula oluzimele lodwa. Inqubo yokusebenza yokulawula isivinini sokuguqulwa kwemvamisa iyafana ngokuyisisekelo nenqubo yokuqalisa ethambile yokulawula isivinini sokuguqulwa kwemvamisa, kodwa kunomehluko. I-cranking drive motor iyishayela ukuthi ijikeleze. Lapho isivinini sokuzungezisa se-synchronous motor sifinyelela ku-1% wejubane elilinganiselwe, i-synchronous motor izoyala uhlelo lokulawula ngokohlelo oluklanyelwe ngemva kokuvulwa kokulawula okuvusa amadlingozi, futhi igumbi lokulawula elijwayelekile lizokhipha “imvume yokuvula. ” “, okungukuthi, vala isiqalo esithambile esibonisa isignali yenguquko kagesi ephezulu yokusebenza kokulawula isivinini sokuguqulwa kwemvamisa. Ngasikhathi sinye, ngokuya ngomyalelo wesiginali, igumbi lokulawula elijwayelekile livala ngokushesha ukushintshwa kwe-voltage ephezulu yesekethe yokulawula eyinhloko yesistimu yokulawula isiqalo esithambile se-synchronous motor frequency conversion speed regulation operation, ukuze i-synchronous motor ibe ngaphakathi. isimo sokusebenza sokuqala esithambile sokulawula ukulawula isivinini sokuguqulwa kwemvamisa.

Ngesikhathi senqubo yokulawula isiqalo esithambile sokuguqulwa kwemvamisa kanye nokuguqulwa kwemvamisa ye-synchronous motor, i-polarity yesigxobo kazibuthe se-rotor ye-synchronous motor ihlala ingashintshiwe, futhi ukujikeleza kuyasheshiswa nemvamisa yokulawulwa kwesivinini sokuguqulwa kwemvamisa, kanye ne-voltage. futhi imvamisa iyanda kancane kancane ukwenza i-synchronous motor isebenze ngesivinini esilinganiselwe. Isilawuli sokuqalisa esithambile sokulawula isivinini sokuguqulwa kwemvamisa.

Ngesikhathi sokusebenza kwe-synchronous motor ene-variable frequency regulation, ngokuya ngokushintsha komthwalo wangempela, i-frequency conversion control regulation system kanye ne-micro industrial electronic control system control system ibona ukulawulwa kwejubane okuzinzile nokunemba kokulawula ukusebenza kwe-vector. .

Ngaphambi kokuma kwe-motor synchronous ekusebenzeni kokulawula isivinini sokuguqulwa kwemvamisa, idivayisi yokusebenza yokulawula isivinini sokuguqulwa kwemvamisa kufanele inciphise ngokuzenzakalelayo ukuphuma kwamanje ibe ku-zero, futhi ivimbe wonke ama-trigger edivayisi yokulawula isivinini sokuguqula imvamisa ngaphambi kokuthi inikeze "imvume yokumisa" isibonisi sesignali. Ngokomyalo wesiginali ebonisiwe, isilawuli esiyinhloko sinqamula ngokushesha ukunikezwa kwamandla okushintshwa kwe-voltage ephezulu yesifunda sokulawula esiyinhloko sedivayisi yokulawula ukulawulwa kwesivinini sokuguqulwa kwemvamisa, futhi kuqeda inqubo yokulawula ukulawulwa kwesivinini sokuguqulwa kwemvamisa.
