Qhov txawv ntawm ntau hom relay yog dab tsi?

Relay yog ib qho kev hloov pauv uas muaj peev xwm tswj tau, hauv kev tswj hluav taws xob sab hauv yog siv dav heev, niaj hnub no peb yuav nkag siab txog nws cov kev faib tawm, kev faib tawm rau peb hom: dav dav, tswj relay, tiv thaiv relay.
electromagnetic relay
Ua ntej, qhov kev hloov pauv dav dav muaj lub luag haujlwm ntawm kev hloov pauv, thiab kev tiv thaiv kev ua haujlwm, cov khoom siv hluav taws xob sib txuas thiab cov khoom hauv lub xeev relay.Electromagnetic relay yog ib hom electromagnetic relay feem ntau muaj ib co coil, los ntawm txoj cai electromagnetic, coil hluav taws xob los tsim cov hlau nplaum, armature yog attracted los ntawm lub magnetic teb, tsav kev sib cuag kev ua.Qhov tshwm sim yog: feem ntau qhib kev sib cuag kaw, feem ntau kaw kev sib cuag disconnected, thaum lub coil fais fab tuag, armature nyob rau hauv qhov kev txiav txim ntawm lub caij nplooj ntoos hlav, feem ntau qhib thiab feem ntau kaw kev sib cuag kuj pib dua. .
solid state relay
Cov khoom hauv lub xeev relays yog kev sib cuag nrog cov hluav taws xob hauv hluav taws xob sab hauv.Raws li tuaj yeem pom los ntawm daim duab saum toj no, ib qho kawg yog qhov kawg input, thiab lwm qhov kawg yog qhov kawg tso tawm.Cov zis kawg yog qhov hloov.Los ntawm kev hloov kho lossis kev tswj hwm ntawm qhov kawg ntawm cov tswv yim, cov zis kawg yog tig thiab tig rau thiab tawm.
Qhov thib ob, kev tswj hwm relay yog: nruab nrab relay, lub sij hawm relay, ceev relay, siab relay thiab lwm yam.
sij hawm relay
Intermediate relays feem ntau muaj thiab tuaj yeem tswj tau ncaj qha los ntawm kev thauj khoom lossis tsis ncaj qha rau lub zog siab load ntawm AC contactor.Time relays feem ntau yog siv rau kev ncua circuits, xws li lub hnub qub daim duab peb sab voltage pib, autocoupling transformer voltage pib, etc.Speed ​​relay yog Feem ntau siv nyob rau hauv lub thim rov qab braking ntawm lub cev muaj zog, lub cev muaj zog nyob rau hauv lub braking lub xeev ceev yog zero, txiav tawm lub hwj chim mov thiab nres.Lub siab relay yog siab rhiab, thiab kev sib cuag txav thaum lub siab ntawm cov kua mus txog ib tug set point. .
Peb, kev tiv thaiv relay yog: thermal overload relay, tam sim no relay, voltage relay, kub relay, thiab lwm yam
