Relays yog switching li siv nyob rau hauv tej controlcircuit los xyuas ib tug mob los yog multiply tus xov tooj ntawm kev sib cuag muaj. Contactors yog switching li siv los tswj lub zog khiav mus rau ib qho load. Feem ntau yog siv rau hauv kev tswj thiab automation circuits, tiv thaiv circuits thiab hloov cov hluav taws xob me me.
Yog li ntawd, yog ib tug contactor ib tug relay?
A tus contactor yog loj relay , feem ntau yog siv los hloov tam sim no rau lub tshuab hluav taws xob lossis lwm lub zog loj.
Ib yam li ntawd, lub luag haujlwm tseem ceeb ntawm contactor yog dab tsi? A tus contactor yog ib qho hluav taws xob tswj hluav taws xob siv rau kev hloov hluav taws xob hluav taws xob hluav taws xob. A tus contactor Feem ntau yog tswj los ntawm lub voj voog uas muaj lub zog qis dua li qhov hloov pauv, xws li 24-volt coilelectromagnet tswj lub 230-volt lub cev muaj zog hloov.
Ib yam li ntawd ib tug yuav nug, qhov txawv ntawm ib tug relay thiab contactor yog dab tsi?
Contactors feem ntau yog tsim rau thiab siv hauv 3-theem daim ntawv thov qhov twg a relay yog siv ntau dua hauv daim ntawv thov ib theem. A tus contactor koom nrog 2 tus ncej ua ke, tsis muaj kev sib koom ua ke nruab nrab lawv, a relay muaj ib qho kev sib cuag uas txuas mus rau qhov chaw nruab nrab.
Relay yog dab tsi thiab nws ua haujlwm li cas?
Relays yog cov keyboards uas qhib thiab kaw circuitselectromechanically lossis electronically. Relays tswj ib qho hluav taws xob hluav taws xob los ntawm kev qhib thiab kaw cov neeg nyob hauv lwm lub voj voog. Raws li relay daim duab qhia, thaum a relay contactis nquag qhib (NO), muaj kev sib cuag qhib thaum lub relay tsis muaj zog.

Lub hom phiaj thiab lub luag haujlwm ntawm kev ua haujlwm yog dab tsi?
Lub operating system muaj peb lub luag haujlwm tseem ceeb: (1) tswj hwm lub khoos phis tawj cov peev txheej, xws li lub chaw ua haujlwm nruab nrab, nco, disk drives, thiab tshuab luam ntawv, (2) tsim kom muaj tus neeg siv interface, thiab (3) ua thiab muab kev pabcuam rau kev siv software
Lub luag haujlwm thiab lub luag haujlwm ntawm Java Developer yog dab tsi?
Java Developer lub luag haujlwm suav nrog: Tsim thiab tsim cov ntawv ntim siab, qis-latency daim ntawv thov rau lub hom phiaj tseem ceeb thiab xa cov khoom muaj txiaj ntsig thiab kev ua haujlwm siab. Kev koom tes hauv txhua theem ntawm txoj kev loj hlob lub neej. Kev sau ntawv zoo tsim, kuaj tau, muaj txiaj ntsig code
Kev tswj relays ua haujlwm li cas?
Lub relay tswj yog ib qho hluav taws xob tivthaiv uas qhib lossis kaw qhov hloov pauv txhawm rau tso cai rau tam sim no ntws los ntawm kev coj tus coil, nrog lub kauj tsis tuaj yeem nkag mus rau hauv kev sib cuag nrog tus tes hloov. Control relays yog cov khoom siv hluav taws xob electromagnetic uas feem ntau tswj cov hluav taws xob txaus ntshai
Dab tsi yog qhov txawv ntawm kev ua haujlwm virtual thiab kev ua haujlwm dhau?
Cov haujlwm virtual tsis tuaj yeem ua tau zoo li qub thiab tsis tuaj yeem ua phooj ywg ua haujlwm ntawm lwm chav kawm. Lawv yeej ib txwm txhais nyob rau hauv lub hauv paus chav kawm ntawv thiab overridden nyob rau hauv derived class. Nws tsis yog qhov yuav tsum tau ua rau cov chav kawm muab tau los hla dhau (lossis rov txhais cov haujlwm virtual), nyob rau hauv cov ntaub ntawv hauv chav kawm version ntawm kev ua haujlwm yog siv
Dab tsi yog qhov zoo sib xws thiab qhov txawv ntawm relays thiab PLC yog dab tsi?
Relays yog electro-mechanical keyboards uas muaj coil thiab ob hom kev sib cuag uas tsis yog NO & NC. Tab sis Programmable Logic Controller, PLC yog lub khoos phis tawj me uas tuaj yeem txiav txim siab raws li qhov kev zov me nyuam thiab nws cov tswv yim & tso tawm
