Izimiso zokuhlela kanye nokuhlela ama-contactor

Ama-contactor ayizingxenye ezibalulekile ezinhlelweni zikagesi futhi asetshenziselwa ukulawula ukuhamba kukagesi esiketheni. Asetshenziswa ezinhlotsheni ezahlukene zokusebenza, okuhlanganisa imishini yezimboni, izinhlelo zokushisa nezomoya, kanye nemishini yokuthutha. Ama-contactor ahlukaniswa ngokohlobo lwamandla alawulayo. Izigaba ezimbili eziyinhloko ama-contactor e-AC kanye nama-contactor e-DC. Kulesi sihloko, sizohlola izimiso zokuhlela kanye nokuhlukanisa ama-contactor, sigxile kakhulu kuma-contactor e-AC.

Izixhumi ze-ACzenzelwe ukulawula ugesi oshintshanayo (AC), ngokungafani nama-contactor e-DC, aklanyelwe ukulawula ugesi oqondile (DC). Umehluko phakathi kwezinhlobo ezimbili zama-contactor usekelwe kakhulu kusekethe eyinhloko ezixhunywe kuyo. Uma ugesi osesekethe eyinhloko kuyi-AC, i-contactor iyi-contactor ye-AC kungakhathaliseki ukuthi i-voltage yekhoyili yokulawula ingakanani. Lo mgomo wokuhlela uqinisekisa ukuthi ama-contactor ayahambisana nohlobo oluthile logesi aklanyelwe ukuwulawula.

Esigabeni se-AC contactor, kunezinhlobo ezimbili eziyinhloko: i-electromagnetic contactor kanye ne-vacuum contactor. Ama-AC contactor e-electromagnetic asebenzisa izindlela ze-electromagnetic, izinhlelo zokuthintana, amadivayisi okucima i-arc kanye nezingxenye ezisizayo ukulawula ukugeleza kokushintshana kwamandla kagesi kusekethe eyinhloko. Ingqikithi ye-AC contactor yenziwe ngamashidi ensimbi e-silicon alaminated, okuwusizo ekunciphiseni ukulahleka kwamandla kagesi kanye ne-hysteresis okubangelwa ukushintshana kwamasimu kazibuthe. Ngaphezu kwalokho, kufakwa indandatho ye-short-circuit ekugcineni kwengqikithi yensimbi ukuze kuqedwe ukudlidliza nomsindo lapho amandla kagesi e-AC ewela zero, okuqinisekisa ukusebenza okubushelelezi nokusebenza kahle.

Ngokuphambene nalokho, ama-contactor e-vacuum nawo awela esigabeni sama-contactor e-AC futhi aklanyelwe ukusetshenziswa kwamandla aphezulu. Lawa ma-contactor afaka idivayisi yokucisha i-arc ye-ceramic ehlanganisiwe evikelwe ngegridi evikelwe kahle esebenza kahle kakhulu ekucimeni ama-arcs akhiqizwa lapho i-contactor ishintsha amasekethe e-AC. Lobu buchwepheshe obuthuthukisiwe buvumela ama-contactor e-vacuum ukuthi aphathe imithwalo emikhulu ye-AC ngokunembile nangokuthembekile.

Uma ukhetha i-contactor ye-AC yohlelo oluthile, kubalulekile ukucabangela uhlobo kanye nomthamo womthwalo. Uma uhlelo lokulawula luqukethe kakhulu imithwalo ye-AC futhi umthamo womthwalo we-DC motor noma we-DC mncane, ama-contactor e-AC angasetshenziswa ukulawula. Kodwa-ke, kubalulekile ukuqinisekisa ukuthi isilinganiso samanje soxhumana nabo sanele ukuphatha umthwalo ngaphandle kwezinkinga.

Ngamafuphi, izimiso zokuhlukanisa kanye nokuhlukanisa ama-contactor zidlala indima ebalulekile ekuqinisekiseni ukuhambisana kanye nokusebenza kahle kwezinhlelo zokulawula ugesi. Ama-contactor e-AC aklanyelwe ukulawula amandla e-AC futhi atholakala ngezinhlobo eziningi ukuze avumelane namakhono nezinhlelo zokusebenza ezahlukene. Ngokuqonda izimiso zokuhlukanisa kanye nokukhetha i-contactor efanele yesicelo esithile, amabhizinisi angaqinisekisa ukusebenza okubushelelezi nokuthembekile kwezinhlelo zawo zikagesi. Kungakhathaliseki ukuthi imishini yezimboni, izinhlelo zokushisa nezomoya, noma imishini yokuhamba, ama-contactor e-AC ayizingxenye ezibalulekile zokusebenza kahle kanye nokuphepha.

I-Mutai Group iqoqe iminyaka engaphezu kweyishumi yesipiliyoni sokukhiqiza nokuthengisa e-USama-circuit breaker, ama-contactor, amandla aphindwe kabiliukushintsha okuzenzakalelayo kokudlulisa (I-ATS) kanye nezinkambu ezihlobene. Silangazelela ithuba lokusebenza nawe.
