Yuav ua li cas yog ib qho electromagnetic relay

Lub hauv paus ntawm niaj hnub hluav taws xob engineering yog raws li nyob rau hauv ob lub ntsiab ntsiab ntawm feem ntau schemes - semiconductor transistor thiab electromagnetic relay. Yog hais tias peb lub hlwb tshem tawm cov ob inventions, nws yog ib qhov nyuaj rau xav txog tej yam dab tsi yuav tau lub tom ntej keeb kwm ntawm noob neej. Tej zaum, nws yuav tau hloov zuj zuj nyob ib ncig ntawm cov Nrab Hnub nyoog, thiab, tej zaum, nyob rau hauv tsis tooj, kev kawm yuav tau ua raws li txoj kev ntawm kev tswj kev loj hlob ntawm lom systems. Tab sis qhia rau peb tawm cov kev xav science ntawv tseeb writers. Ib yam yog tseeb: electromagnetic relays rau tag nrho cov hluav taws xob engineering yog tib yam li hais tias ntawm ib tug nrog combustion cav rau ib tug niaj hnub thauj. Qhov ntawd yog - ib tug indispensable tivthaiv.

Yuav ua li cas puas muaj tus electromagnetic relay?

Tus tsim ntawm no Circuit Court caij yog heev yooj yim. Qhov no qhia rau nws cov high ntseeg: nyob rau hauv ib co industries tseem ua relays 1940 qauv xyoo.

Ua ntej piav txog tus qauv, nws yog tsim nyog yuav tau nco qab ib yam ntawm cov kev cai ntawm physics - electromagnetism. Nws yog lub npe hu hais tias nyob ib ncig ntawm tej cov ntaub ntawv uas los ntawm kev uas hluav taws xob tam sim no ntws, muaj ib tug tshwj xeeb zoo ntawm qhov teeb meem - ib tug sib nqus teb. Nws lub zog (tej zaum) yog nyob ntawm ob tsis: tus nqi ntawm cov ntws tam sim no thiab qhov ntev ntawm tus neeg xyuas pib. Nws yog ib cuab kev tias yog hais tias qhov ntev ntawm txhua unit generates ib lub teb, tus neeg xyuas pib yog ntev tshaj li, qhov ntau pronounced cov magnetic nyhuv. Qhov no txhais tau tias yog hais tias tus tom ntej no nrog xws li ib tug neeg xyuas pib nyob ib tug hlau kwv, ces nws yuav tau los ntawm lub ntiajteb txawj nqus. Yog hais tias lawv cov nqi yuav txaus, tus kwv yuav txav. Obviously ob: kom lub teb siv los ntawm kev ua qhov ntev ntawm tus neeg xyuas pib tsis yog yooj yim heev - tus ntaus ntawv yuav tsum tau kev cog lus ntawm, thiab tag nrho cov teb vector mloog zoo ntawm ib tug taw tes thiab tsis tsuag raws conductive khoom. Ua tam sim no kuj irrational, txij li thaum nws ua ntev li cua sov thiab cov uas tsis-pom siv ntawm cov khoom. Txawm li cas los, muaj ib cov tshuaj.

Nws yog tsis muaj direct daim ntawv thov ntawm cov hlau, thiab cov kauj tub ntxhais. Qhov no pub rau cov kev siv ntawm kilometers ntawm nyias hlau mus rau ib tug me me volume.

Electromagnetic relay comprises cia li hauv ib kauj. Qhov thib ob yog ib feem ntawm cov qauv - tshwj xeeb zoo li tus hlau phaj muaj ib tug degree ntawm txoj kev ywj pheej. Hais tias yog, thaum twg muaj ib tug sib nqus teb, lub phaj yog attracted mus rau thaum xaus lub ntsej muag ntawm lub kauj. Nrog rau cov disappearance ntawm lub tam sim no cov nyhuv tsis tu tsis tseg thiab rov qab los caij nplooj ntoos hlav discards lub phaj rau nws cov thawj txoj hauj lwm.

Thaum lub bar attracts lub taag choj - ib pab pawg neeg ntawm rooj noj hu. Qhov thib ob ntawm lawv (rigidly tsau) yog tom ntej no. Thaum lub phaj yog moog, cov neeg raug kaw. Yog hais tias lawv muaj nyob rau hauv lub Circuit Court, yog tswj lub lag luam los ntawm cov kauj yuav hloov lub kev cob cog rua circuits. Qhov ntawd yog ua hauj lwm electromagnetic relay. Incidentally, nyob ntawm seb tus qauv ntawm arrangement ntawm tsau hu, lawv yuav tsum tau nquag kaw (NC thaum ib tug sib nqus teb) thiab feem ntau qhib (sau saw).

Electromagnetic relay AC tsim muaj xws li ib tug tshwj xeeb kauj neeg xyuas pib uas nws teb tsis pub rattling vim qhov xwm ntawm tus tam sim no zaus.
