Tam sim no relays - lub ntau yam thiab lub ntaus ntawv

Tam sim no relay - ib tug ntaus ntawv uas yog feem ntau siv rau lub teeb liab tam sim no tshaj ib tug tej yam tshuaj Circuit Court. Tsis tas li ntawd, nws yog siv los yog lov tes taw rau hauv Circuit Court nyob rau hauv cov kev tshwm sim ntawm luv luv circuits los yog overloads. Dej ntws hauv qab thu dej relays yog siv ntau tsawg zaus. Xws li yog tsim rau cov tearing qhov hluav taws xob Circuit Court thaum ib tug tej yam tsawg kawg nkaus tam sim no tus nqi.

Muaj ntau ntau ntau hom kev hluav taws xob xws li hwj chim keyboards. Lawv txawv nyob rau hauv kev tsim kho thiab kev khiav hauj lwm hauv paus ntsiab lus. Yog hais tias peb tham txog qhov thiaj li hu ua classical ntsuas, nws yog ib tug movable thauj tog rau nkoj rau ntawm springs, uas tswj cov neeg thiab cov kauj tub ntxhais (feem ntau yog hlau). Thaum tam sim no kis tau los ntawm cov kauj tsim ib tug sib nqus teb ntawm ib tug tej yam ntau. Hais txog kev txiav txim ntawm no magnetic teb yog magnetized thiab cov kauj tub ntxhais pib nyiam cov armature. Yog li, rau cov neeg yuav tau triggered.

Cov kauj ntawm lub ntaus ntawv muaj ib tug ob peb windings, tab sis muaj ib tug loj lub cheeb hlau (li opposed rau, e.g., tib voltage relays). Cov kab uas hla ntawm lub hlau nyob rau hauv lub tam sim no, los yog ntau tshaj precisely, qhov ntau ntawm cov kwv yees li tam sim no tus nqi. Qhov no achieves ib tug voltage nco. Qhov no yog qho tseem ceeb heev, vim hais tias cov kauj yog kev cob cog rua nyob rau hauv series rau qhov uas tswj Circuit Court.

Ib txhia DC relays muaj adjustable tam sim no mus txawv tebchaws. Nyob rau hauv Feem ntau, qhov no yog ua tiav los ntawm kev hloov lub armature caij nplooj ntoos hlav nro. Relay AC, uas yog siv los tswj siab currents yuav hloov los ntawm transformers.

Qhov tseem ceeb tshaj cov yam ntxwv ntawm no tiv thaiv ntaus ntawv yog lub teb lub sij hawm. Devices ntawm no hom uas yuav siv tau rau kev tiv thaiv tiv thaiv luv luv circuits muaj switching lub sij hawm tsis ntau tshaj li ob peb lub kaum ntawm milliseconds.

Khoom hauv lub xeev relay DC Circuit Court ua ncua sij hawm thaum kaw. Eliminates qhov no tau cuav positives nyob rau hauv cov ntaub ntawv ntawm luv luv-lub sij hawm tam sim no yuav tsub kom. Xws li ib tug ntaus ntawv feem ntau muaj kev tswj ntawm kev khiav hauj lwm lub sij hawm.

Ib qho ntawm feem ntau cov hom ntawm kev tiv thaiv pab kiag li lawm yog lub thermal relay tam sim no. Nws yog ib tug bimetallic phaj, muab ib cov cua kub lub caij ua los ntawm ib cov khoom uas muaj ib tug siab resistivity (e.g., nichrome). Lub phaj yog muaj li ntawm cov ntaub ntawv uas sib txawv coefficient ntawm thermal expansion, uas bends raws li qhov cua kub thiab ua rau tus tes hloov qhov mechanism. Cov lus teb lub sij hawm ntawm xws li ib tug ntaus ntawv nyob rau hauv lub tam sim no - lub siab nws yog, qhov ntau sai heev sov li phaj, thiab lub me teb lub sij hawm.

Ib tug hluav taws xob overcurrent relay rau kev siv zoo instantaneous overload dawm taw. hluav taws xob relay Circuit Court yuav ua lub teeb nyob rau hauv raws li predetermined tsis thiab yam ntxwv nyob rau hauv ua ntej. Koj yuav tau teem lub pub nyiaj pab ntau tshaj tam sim no thiab lub sij hawm ncua thaum disconnecting. Tej tam sim no relays yuav ua tau ntau yam thiab constants. Cov pab kiag li lawm feem ntau tuaj nyob rau hauv daim ntawv ntawm cov ua-nyob rau hauv rau ntau pab kiag li lawm.
