Low-voltage AC contactors anonyanya kushandiswa kushandura nekudzima magetsi emidziyo yemagetsi, iyo inogona kudzora midziyo yemagetsi kubva kure kure, uye kudzivirira kukuvara kwemunhu kana uchidzima nekudzima magetsi emidziyo. Kusarudzwa kwe AC contactor kwakakosha zvikuru pakushanda kwemagetsi emagetsi uye tambo dzemagetsi.
1. Chimiro uye parameters ye AC contactor
Mukushandiswa kwakajairwa, iyo AC yekubatanidza mudziyo inodiwa kuve ne compact chimiro, nyore kushandisa, yakanaka magineti inofuridza mudziyo weinofamba uye static contacts, yakanaka arc yekudzima mhedzisiro, zero flashover, uye diki tembiricha inokwira. Zvinoenderana nearc yekudzima nzira, yakakamurwa kuita mhepo mhando uye vacuum mhando, uye zvinoenderana nemaitiro ekushanda, yakakamurwa kuita electromagnetic mhando, pneumatic mhando uye electromagnetic pneumatic mhando.
Iwo akatemerwa voltage ma parameter eiyo contactor akakamurwa kuita yakakwira voltage uye yakaderera voltage, uye yakaderera voltage inowanzo 380V, 500V, 660V, 1140V, nezvimwe.
Magetsi emagetsi anokamurwa kuita alternating current uye akananga ikozvino zvichienderana nerudzi. Current parameters zvinosanganisira rated kushanda ikozvino, vakabvumirana kudziyisa ikozvino, kugadzira ano uye kutyora ano, akabvumirana kupisa ikozvino ebetsero shamwari uye pfupi-nguva kutsungirira ikozvino contactor, etc. The general contactor muenzaniso parameters kupa vakabvumirana kudziyisa ikozvino, uye pane akati wandei rated. kushanda kwezvino kunoenderana neyakabvumiranwa kupisa ikozvino. Semuenzaniso, yeCJ20-63, iyo yakatemerwa inoshanda ikozvino yeakanyanya kuonana yakakamurwa kuita 63A uye 40A. 63 mune yemuenzaniso parameter inoreva iyo yakabvumiranwa kupisa ikozvino, iyo ine hukama neyakagadzika chimiro chegoko reiyo contactor, uye yakatemerwa yekushanda ikozvino inoenderana neyakasarudzwa mutoro ikozvino, inoenderana neiyo voltage level.
AC contactor coils dzakakamurwa kuva 36, 127, 220, 380V uye zvichingodaro maererano voltage. Nhamba yematanda ekubatanidza inoparadzaniswa kuva 2, 3, 4, 5 matanda uye zvichingodaro. Kune akati wandei mapeya evabatsiri anobatika zvinoenderana neanowanzo kuvhurika uye anowanzo kuvharwa, uye anosarudzwa zvinoenderana nezvinodiwa zvekutonga.
Mamwe maparamendi anosanganisira kubatana, kutyora nguva, hupenyu hwemagetsi, hupenyu hwemagetsi, huwandu hunotenderwa hwekushanda, huwandu hunobvumirwa wiring dhayamita, zviyero zvekunze uye zviyero zvekuisa, etc.Classification of contactors
Common Contactor Types
Shandisa kodhi kodhi yeyakajairwa mutoro muenzaniso wakajairika zvishandiso
AC-1 isiri-inductive kana micro-inductive load, resistive load resistance furace, hita, nezvimwe.
Kutanga nekutyoka kweAC-2 ronda induction mota Cranes, compressors, hoists, nezvimwe.
AC-3 cage induction mota kutanga, kupwanya mafeni, pombi, nezvimwe.
AC-4 cage induction mota kutanga, reverse braking kana kuvhara-off mota fan, pombi, muchina chishandiso, nezvimwe.
AC-5a mwenje wekuburitsa pa-off high-pressure gasi ekuburitsa marambi akadai semarambi emercury, marambi ehalogen, nezvimwe.
Mwenje we AC-5b incandescent unodzima
AC-6a transformer on-off welding machine
On-off capacitor ye AC-6b capacitor
AC-7a Midziyo yemumba uye yakafanana yakaderera-inductance mutoro microwave oveni, maomesa emaoko, nezvimwe.
AC-7b yemumba mota inoremedza firiji, muchina wekuwachisa uye rimwe simba rekubatidza nekudzima
AC-8a mota compressor ine hermetic firiji compressor ine bhuku reset yakawandisa kuburitswa
AC-8b mota compressor ine hermetic firiji compressor ine bhuku reset yakawandisa kuburitswa
