Enye iwukuhlola izici eziyinhloko zokwehluleka kwemvelo ngokulingisa indawo yokusetshenziswa yangempela (njengezinga lokushisa, umfutho womoya, umswakama, isifutho sikasawoti, umthelela, ukudlidliza, izimo zamanje zokusetshenziswa kwangaphandle, ikakhulukazi umthelela wejika lokushaja).Okunye ukuhlaziya nokuqinisekisa ukwakheka kwezinto ezisemqoka ezifana nezinto zokuxhumana, indawo yokuklama indawo yokuxhumana kanye nezinto zokwakha zegobolondo, kucatshangelwe izici eziyinhloko zesici esibalulekile ngokombono wangaphakathi, futhi sihlanganise le datha ukuze kuhlaziywe izinga lokungaphumeleli kokulandela. -idatha yokuthengisa.Eqinisweni, kunezici eziphazamisayo zangaphandle: kufaka phakathi isakhiwo se-arc bin esihlukile se-contactor, isakhiwo sekhoyili yedrayivu (manje isakhiwo sekhoyili enezigaba ezimbili) kanye nemodi yokulawula idrayivu, umehluko wesekethe yangaphandle yedrayivu, amandla athile. -ukugcina i-drive circuit.
Yilokhu esicwaninga ngakho futhi siqongelele idatha, bese siyayiqongelela.
Noma kunjalo, umehluko omkhulu phakathi kwe-contactor kanye ne-relay isesimeni sokulayisha esinqanyuliwe
Ama-contact asetshenziselwa uhlobo lomthwalo olunogesi ophezulu, wamanje ophezulu noma kokubili.Ngokuvamile esetshenziselwa imishini engaphezu kuka-15 amps noma 3kW.Ukuze uthole amanani aphansi, i-relay evamile isetshenziswa.
Qaphela: empeleni, sisebenzisa i-contactor kanye ne-relay futhi ukubona izinto abazithandayo, awukholwa ukubona ukuthi amaJapane asebenzisa kanjani: isethulo sibhalwe kanjalo, lolu chungechunge aluyona i-contactor?
Kusukela design ezifuywayo ngokuyinhloko has lezi umehluko, singabantu iphuzu ngokuqinile noma ukuhlukanisa ngezansi
1) Umehluko wamanje oqhutshwa ukuxhumana
Ngokuvamile, umenzi uzonikeza inani lefekthri lokumelana ne-conductive, futhi sizohlola imodeli yokushisisa yesikhathi eside yawo wonke othintana naye ngokwaleli nani.Leli phuzu lidinga futhi ukuthi sixoxe ngokucophelela, liyini izinga lokushisa langempela lokuxhumana?Ingabe othintana naye uthinta ukushisisa kwendlu yokugcina izinto, ikakhulukazi ukwakheka kophawu lwangaphandle?Usayizi wangempela wokuxhumana, okokusebenza, nesimo sokuxhumana sizoba nomthelela omkhulu kulezi zici ezifanayo eziphelele.
Uma empeleni sihlukanisa i-contactor, othintana nabo abancane.Nakuba abanye othintana nabo behlukaniswa ngosayizi abahlukene bamanje nabahlukene, sidinga ukusungula isizindalwazi sangempela kule ndawo, ukukhetha amasampula wokuguga kwamakhoyili = ukuqapha ukumelana nokuxhumana nokuqapha izinga lokushisa lokuxhumana.
Inkampani yenethiwekhi yokuxhumana
Inkampani yenethiwekhi
Lokhu kushisa, ikakhulukazi noma i-impedance yokuxhumana ebhowudi engenhla kanye nokuphazamiseka kokuxhumana okumile izingxenye ezimbili zokushisa.
2) I-contactor ifakwe i-arc suppression mechanism, kodwa i-relay ngokuvamile ayinayo.
Lapho kulayishwa amandla aphezulu, ama-currents angase anqamule izindawo zokuxhumana lapho iswishi iguqulwa.Ukushaqeka kukagesi kungase kubangele umonakalo omkhulu endaweni yokuxhumana, kubangele ukwehluleka kwephoyinti lokuxhumana ngaphambi kwesikhathi sempilo yayo elindelekile.Ku-voltage ephansi ene-relarelay.Lokhu kucacisa okuyisisekelo kunquma umehluko ezicini zekhefu:
Umfanekiso 1. Izici zento yokuxhumana zibaluleke kakhulu
Umdwebo wokuhlukaniswa, nokuhlaziywa kokuphepha kwesistimu yamandla emoto kagesi ezimeni eziphuthumayo, thina ngakolunye uhlangothi ekuhlukaniseni ukucatshangelwa, sidinga ukurekhoda ngokuqondile futhi sicabangele ukuphepha kwemoto lapho isimo sifuna ngempela ukwenza kanjalo, njengokushayisana, njengokuthi ukwehla kwamandla kagesi, izinga lokushisa lenyuka kakhulu, alikwazi ukukhipha amandla njengezimo ezishisayo.
3) Umehluko phakathi kwe-contactor kanye ne-relay amandla adliwe esimweni sokuqhuba ukugcinwa
I-contactor idinga idizayini ye-actuator ukuze ishintshe othintana nabo abakhulu, ngaleyo ndlela idinga ikhoyili ye-solenoid enkulu kakhulu, edla amandla amanje kakhulu ngesikhathi sokuqalisa nokugcinwa.Ngokuphambene, i-electromagnetic encane ku-relay kulula ukuyishintsha futhi ayidingi okwamanje okuningi.
