Enye kukuhlola eyona miba iphambili yokusilela kokusingqongileyo ngokulinganisa imeko-bume yokwenyani yokusetyenziswa (efana nobushushu, uxinzelelo lomoya, ukufuma, isitshizi setyuwa, impembelelo, ukungcangcazela, ukusetyenziswa kwangaphandle iimeko zangoku, ngakumbi impembelelo yegophe lokukhupha intlawulo).Enye kukuhlalutya kunye nokuqinisekisa ukubunjwa kwezixhobo eziphambili ezifana nezixhobo zoqhagamshelwano, indawo yokuyila indawo yoqhagamshelwano kunye nemathiriyeli yeqokobhe, qwalasela iimpawu zomgaqo wezinto ezibonakalayo ngokwembono yangaphakathi, kwaye udibanise le datha ukuhlalutya isantya sokungaphumeleli emva kokusilela. -idatha yokuthengisa.Enyanisweni, kukho izinto eziphazamisayo zangaphandle: kubandakanywa isakhiwo se-arc bin esahlukileyo se-contactor, isakhiwo se-coil coil (ngoku isakhiwo se-coil esinezigaba ezimbini) kunye nemodi yokulawula idrayivu, umahluko wesekethe yangaphandle, amandla athile. -Saving drive circuit.
Ezi zinto senza uphando kwaye siqokelele idatha, kwaye emva koko siqokelela.
Nangona kunjalo, umahluko omkhulu phakathi komnxibelelanisi kunye ne-relay ilele kwimeko yomthwalo onqanyuliweyo
Abanxibelelanisi basetyenziselwa uhlobo lomthwalo olunombane ophezulu, umsinga ophakamileyo okanye zombini.Ngokuqhelekileyo isetyenziselwa izixhobo ezine-amps ezingaphezu kwe-15 okanye i-3kW.Kumanani aphantsi, i-relay eqhelekileyo isetyenziswa.
Qaphela: eneneni, sisebenzisa i-contactor kunye ne-relay kukubona izinto abazithandayo, awukholelwa ukubona indlela amaJapan asebenzisa ngayo: isandulela sibhaliwe njalo, olu luhlu alukho unxibelelwano?
Ukusuka kuyilo lwasekhaya ikakhulu unalo mahluko, singqongqo okanye ukwahlula ngezantsi
1) Umahluko kungoku oqhutywa luqhagamshelwano
Ngokuqhelekileyo, umenzi uya kunika ixabiso lefektri yokuchasana kwe-conduction, kwaye siya kuvavanya imodeli yokufudumeza ixesha elide loqhagamshelwano lonke ngokweli xabiso.Le ngongoma ikwafuna ukuba sixoxe ngononophelo, yintoni iqondo lobushushu lokwenene loqhagamshelwano?Ngaba uqhagamshelwano luchaphazela ukufudumeza kwendawo yokugcina impahla, ngokukodwa isakhiwo sokutywinwa sangaphandle?Ubungakanani bokwenene boqhagamshelwano, izinto eziphathekayo, kunye nemeko yoqhagamshelwano iya kuba nempembelelo enkulu kwezi mpawu zilandelayo ezipheleleyo.
Xa ngokwenene sithatha ngaphandle umnxibelelanisi, abafowunelwa abancinci.Nangona abanye abafowunelwa bahlulwe ngokwahlukileyo ngoku kunye nobukhulu obahlukeneyo boqhagamshelwano, kufuneka siseke isiseko sedatha yokwenyani kule ndawo, ukukhetha iisampulu zokuguga kwekhoyili = ukujongwa kokumelana nokujongana nobushushu bokunxibelelana.
Umnxibelelanisi womnxibelelanisi
Umthwali we-Relay
Obu bushushu, ikakhulu okanye uqhagamshelo olungaphezulu oludityanisiweyo oludityanisiweyo kunye ne-static yoqhagamshelo lwe-impedance kwiindawo ezimbini zobushushu.
2) Umnxibelelanisi uxhotyiswe nge-arc yokucinezela indlela, kodwa i-relay ayinayo.
Kwimithwalo yamandla ephezulu kakhulu, imisinga inokuthi inqumle iindawo zoqhagamshelwano xa iswitshi iguqulwa.Ukothuka kombane kunokubangela umonakalo omkhulu kwindawo yoqhagamshelwano, kubangele ukusilela kwindawo yoqhagamshelwano ngaphambi kobomi obulindelekileyo.Kwi-voltage esezantsi kunye ne-relarelay.Olu lwazi lusisiseko lumisela umahluko kwiimpawu zekhefu:
Umzobo 1. Iimpawu zezinto zoqhagamshelwano zibaluleke kakhulu
Umzobo wokuqhekeka, kunye nohlalutyo lokhuseleko lwenkqubo yamandla ezithuthi zombane ezingxamisekileyo, thina kwelinye icala ekwahlukaneni koqwalaselo, kufuneka sirekhode ngokuthe ngqo kwaye siqwalasele ukhuseleko lwesithuthi apho ilizwe lifuna ngokwenene ukwenza njalo, njengokungqubana, njenge. ukwehla kwamandla ombane, iqondo lobushushu lenyuka ngokukhawuleza, alikwazi kukhupha amandla afana neemeko zokubaleka kwe-thermal.
I-3) Umahluko phakathi kwe-contactor kunye ne-relay ngamandla asetyenzisiweyo kwisimo sokuqhuba ukugcinwa
I-contactor ifuna ukuyilwa kwe-activator ukuba itshintshe abafowunelwa abakhulu, ngaloo ndlela ifuna i-coil ye-solenoid enkulu kakhulu, edla ngokugqithisileyo ngexesha lokuqalisa kunye nokugcinwa.Ngokwahlukileyo, i-electromagnetic encinci kwi-relay kulula ukuyitshintsha kwaye ayifuni kakhulu okwangoku.
