Inhlangano kanye nokusetshenziswa kokushintsha izinto zamandla, abathintwayo, ama-Frequency Inverters, kanye nama-Relays

Ezinhlelweni zesimanje zikagesi kagesi, izinto zikagesi ezishintshayo (i-SMPS), othintana nabo, iziguquli ezishintshashintshayo, futhi zidlulisela indima ngayinye ebalulekile yokudlala, futhi ukusebenza kwazo ngokubambisana kwenza ukulawula okuvumelana nezimo nokusebenza kahle kwemishini kagesi. Lesi sihloko sizodingida izinhlangano phakathi kwalezi zisetshenziswa nezindlela zazo zokuzisebenzisa.

I. Uhlolojikelele Lwedivayisi

1. Ukushintsha Ukunikezwa kwamandla (SMPS)
   Ukunikezwa kwamandla okushintshwayo kuyidivayisi esebenza kahle yokuguqula amandla elawula futhi izinze amandla kagesi aphumayo ngokushintsha ngokushesha izingxenye zikagesi (njengama-transistors). Uma kuqhathaniswa nezinto ezisetshenziswayo zomugqa wendabuko, ukushintshanisa kwamandla kunikeza ukusebenza kahle okuphezulu kanye nosayizi omncane nesisindo. Umgomo oyinhloko wokusebenza wokushintshwa kwamandla kagesi ubandakanya ukulawula ukudluliswa kwamandla kagesi ngokushintsha ngokushesha izici zokushintsha kwe-elekthronikhi, ngaleyo ndlela kuzuzwe ukuguqulwa nokuqina kwamandla kagesi.

   

2. Oxhumana naye
   I-contactor iyiswishi ye-electromagnetic ezenzakalelayo elungele ukuxhuma noma ukunqamula amasekhethi e-AC kanye ne-DC kanye namasekhethi okulawula umthamo omkhulu ukusuka kude. Ayinikezi kuphela amandla okusebenza okuzenzakalelayo okukude kanye nemisebenzi yokuvikela ukukhishwa kwe-undervoltage kodwa futhi iqhosha nekhono eliphezulu lokulawula, ukwethembeka, ukusebenza kahle kokusebenza, nempilo ende yesevisi.

   
   
   

3. I-Frequency Inverter
   I-inverter yefrikhwensi iyithuluzi elilawula isivinini sokusebenza semoto kagesi ngokushintsha imvamisa yokuphakelwa kwamandla, ilungele ikakhulukazi izinhlelo zokusebenza ezidinga isivinini esinembile kanye nokulawulwa kwetorque. I-frequency inverter iqala iguqule i-AC ibe yi-DC, bese isebenzisa isekethe yokuguqula ukuguqula i-DC ibuyele ku-AC ngefrikhwensi eguquguqukayo, ngaleyo ndlela ishayele injini kagesi.

4. I-Relay
   I-relay iyithuluzi lokulawula likagesi elibangela ushintsho olunqunywe kusengaphambili lwenani elilawulwayo kwisekethe yokuphuma kukagesi lapho uguquko lwenani lokokufaka (isikhuthazo) lufinyelela izimfuneko ezicacisiwe. Isungula ubudlelwano obusebenzisanayo phakathi kwesistimu yokulawula (input circuit) kanye nesistimu elawulwayo (output circuit).

   

II. Ukuhlaziywa Kwenhlangano

1. Ukushintsha Ukunikezwa kwamandla kanye Nokuxhumana
   Ukunikezwa kwamandla okushintshayo kunikeza amandla kagesi we-DC ozinzile ku-contactor, okuqinisekisa ukubandakanyeka okuthembekile nokukhululwa koxhumana naye. Kumasistimu okulawula ugesi, ugesi oshintshayo ngokuvamile usebenza njengomthombo wamandla oyinhloko, uhlinzeka ngamandla kagesi azinzile kulo lonke uhlelo.

2. I-Contactor kanye ne-Frequency Inverter
   I-contactor idlala indima ekuxhumeni noma ekunqamuleni ukunikezwa kwamandla kumotho kagesi kumasistimu okulawula i-inverter. Uma isiguquli sefrikhwensi sidinga ukuqala noma ukumisa injini kagesi, ilawula ukubandakanyeka nokukhululwa kwesixhumi esithinta ukuzuza ukuxhumeka kokuphakelwa kwamandla noma ukunqanyulwa. Ukwengeza, i-contactor ingavikela i-inverter ye-frequency kumaphutha afana nokulayishwa kwemoto.

3. I-Frequency Inverter ne-Relay
   Ama-frequency inverters avame ukuxhunywa futhi alawulwe namanye amadivaysi kagesi ngokusebenzisa ama-relay. Isibonelo, ama-relay angalawula ukuvulwa nokuvalwa kwamasekhethi ahlobene phakathi nezinqubo zokuqalisa kanye nokuvala shaqa kwe-inverter frequency. Ngaphezu kwalokho, lapho i-inverter yefrikhwensi ithola amaphutha afana nokugcwala kwemoto noma i-overcurrent, ingakhipha amasiginali ye-alamu noma inqamule ukunikezwa kwamandla ngokusebenzisa ama-relay.

4. Uhlelo lokusebenza oludidiyelwe
   Ezinhlelweni ezisebenzayo, izinto ezisetshenziswayo zokushintsha amandla, othintana nabo, ama-inverter ama-frequency, nama-relay ngokuvamile asetshenziswa ngokuhlanganiswa ukwakha uhlelo oluphelele lokulawula ugesi. Isibonelo, ezinhlelweni zokuphakelwa kwamanzi ezinengcindezi engaguquki, ama-PLC angakwazi ukulawula iziguquli ezishintshashintshayo ukuze kuzuzwe ukusebenza kwesivinini esiguquguqukayo samaphampu, kuyilapho othintana naye kanye nama-relay asetshenziselwa ukuxhuma nokunqanyulwa kwamandla, imisebenzi ye-alamu enephutha, nokuningi.
