Impendulo enyanisekileyo: akukho phawu "lungcono" lwe-AC capacitor. I-capacitor efanelekileyo ye-air conditioner yakho, i-motor motor okanye i-compressor igqitywe ngokucaciswa, ukusetyenziswa kunye nomgangatho wokuvelisa - kungekhona ngegama eliprintiweyo kwimeko. I-capacitor eyakhiwe kakuhle evela kumenzi owaziwayo omncinci uya kudlula inxalenye ye-brand-brand eyayingachazwanga kakuhle ngomsebenzi.
Eyona nto ihlukanisa ii-capacitors ezilungileyo kwizinto ezimbi luhlu olufutshane lweenyaniso zobugcisa: ukunyamezela kwe-capacitance, i-voltage elinganisiweyo, umgangatho wefilimu ye-dielectric, iziqinisekiso zokhuseleko kunye ne-QC yefektri engaguqukiyo. Esi sikhokelo sichaza indlela yokugweba i-AC capacitor njengengcali, kwaye yintoni onokuyijonga kubenzi be-ac capacitor xa uthenga kwisikali.
Yintoni eyenziwa yi-AC Capacitor
I-AC capacitor igcina kwaye ikhuphe amandla ombane ukunceda isigaba esinye seenjini ze-AC ziqale kwaye zisebenze ngokufanelekileyo. Kwizixhobo zemihla ngemihla, iintsapho ezintathu zilawula:
- CBB60 - ii-capacitors ezijikelezayo ezijikelezayo kwiimpompo, ii-compressors kunye neenjini eziqhelekileyo;
- CBB61 - ii-compact fan capacitors ezisetyenziswa kwiifeni zesilingi, iifeni zokukhupha kunye nezivutheli ze-HVAC;
- CBB65 - i-oyile ejikelezayo egcwele i-run / i-capacitors yokuqalisa i-air-conditioner compressors, ngokuqhelekileyo ilinganiswe nge-370 VAC okanye i-440 VAC.
Bobathathu basebenzisa ifilimu ye-polypropylene enesinyithi njenge-dielectric, enika ipropati yokuziphilisa eyenza i-capacitor iphile kwiimpazamo ezincinci zangaphakathi endaweni yokusilela ngokuthe ngqo.
Kukho iindima ezimbini ezisebenzayo:
- Qhuba ii-capacitors hlala kwisiphaluka ngexesha lokusebenza, ukuphucula ukusebenza kwemoto kunye ne-torque;
- Qala ii-capacitors bonelela nge-torque ephezulu okomzuzwana ngexesha lokuqalisa, emva koko uphume kwisekethe.
Ukutshatisa uhlobo oluchanekileyo, amandla (µF) kunye nevoltheji (VAC) ngumgaqo wokuqala wokukhetha i-capacitor — i-"better brand" capacitor enomlinganiselo ongeyiyo isaya kusilela okanye yonakalise imoto.
Kutheni le nto "Ibhrendi Elilungileyo" lixhomekeke kwiSicelo
