AC vacuum contactors inoita basa rakakosha mukuchengetedza kutendeseka uye kuchengetedzeka kwemaindasitiri emagetsi masisitimu. Aya macontactor anogonakubata high voltages uye currents kuve nechokwadi kushanda zvakanaka uye kudzivirira downtime. Mune ino blog, isu tichaongorora mukati meiyo huru yedunhu voltage uye ikozvino ratings yeAC vacuum contactors, tichiratidza kukosha kwavo mumaindasitiri ekushandisa.
Main redunhu rated voltage:
AC vacuum contactors dzakagadzirirwa kutsungirira zvakasiyana-siyana zvinodikanwa. Iyo yakatemerwa voltage yedunhu guru inoreva kune yakakwirira voltage iyo iyo contactor inogona kushanda yakavimbika. Iine main circuit rating ye1140V, aya macontactor akashongedzerwa zvakakwana kubata hutsinye hwemaindasitiri nharaunda. Izvi zvinogonesa kugadzikana kwemagetsi uye kuderedza njodzi yekukanganiswa kwemagetsi, kuchengetedza maitiro akakosha.
Main redunhu rated current:
Iyo yakayerwa ikozvino yedunhu guru ndiyo imwe yakakosha parameter inotsanangura mashandiro eiyo AC vacuum contactor. Inosarudza kunonyanyisa ikozvino inogona kuyerera kuburikidza contactor pasina kukanganisa kushanda kwayo. AC vacuum contactors ine main circuit ratings ye630A uye 800A yakanakira maindasitiri maapplication anosanganisira mitoro inorema. Aya macontactor anobata zvisingaite zvinodiwa zvemagetsi zvemotor, transformer, uye mamwe ma-high-power midziyo.
Zvakanakira zve AC vacuum contactor:
AC vacuum contactors vane akasiyana siyana mabhenefiti anovaita ivo sarudzo yekutanga yemaindasitiri maapplication. Nehunyanzvi hwavo hwepamusoro-vacuum switching tekinoroji, aya macontactor ane hunyanzvi hwekudzvinyirira arc, kuve nechokwadi chekuchengetedza uye kwakavimbika kushanda. Iyo yakakwidziridzwa yekutyora kweiyo 4800A uye 6400A inovhiringa ikozvino nekukurumidza uye nemazvo, kudzivirira chero kukuvara kuhurongwa.
Kuvimbika uye hupenyu hurefu:
AC vacuum contactors inogara kwenguva refu. Nehupenyu hwemagetsi hwepamusoro (AC3 hupenyu) hwemamiriyoni ekushanda uye hupenyu hwemakanika hunosvika mazana matatu ezviuru zvekushanda, vanobatika ava vanogona kumirisana nenzvimbo dzakaomarara dzemaindasitiri. Kuvimbika kwavo uye kusimba kwavo kunoratidzwa zvakare nekugona kubata-nguva pfupi-pfupi yekushanda ma frequency anosvika mazana maviri ekushanda paawa uye gumi 000 maoparesheni paawa (AC3 uye AC4 frequencies zvakateerana).
mukupedzisa:
AC vacuum contactors zvinhu zvakakosha mumaindasitiri emagetsi masisitimu ayo anovimbisa kusakanganiswa kuyerera kwesimba uye kuderedza njodzi yekutadza kwemagetsi. Nechiyero chikuru chedunhu re1140V uye chiyero chikuru chedunhu re630A ne800A, macontactor aya akagadzirwa kuti asangane nezvinodiwa zvebasa rinorema. Kuvimbika kwavo, kurarama kwenguva refu uye kuita kwakatanhamara kunoita kuti vave sarudzo yekutanga mumaindasitiri akasiyana siyana pasi rese. Chengetedza mari muAC vacuum contactors kuti ishongedze system yako yemagetsi nesimba uye kuvimbika kunodiwa pakushanda kusamira.
