Schneider Overload Relay Xaiv Daim Ntawv Qhia: Kauj Ruam-by-Step Protection Guide

Xaiv txoj cai Schneider overload relay yog qhov tseem ceeb rau kev tiv thaiv lub cev muaj zog, txo qis sijhawm, thiab ua kom muaj kev ua raws li cov qauv kev nyab xeeb. Schneider cov kab kos duab xaiv ua kom yooj yim rau cov txheej txheem no, thiab los ntawm kev sib koom ua ke nrog kev ntseeg siab los ntawm Simply Buy, koj yuav ruaj ntseg rau qhov tseeb thiab kev ntseeg siab.

Precision Protection rau koj cov Motors

Kev tiv thaiv lub cev muaj zog yeej tsis yog ib qho loj-haum-tag nrho. Txhua lub cev muaj zog muaj qhov xav tau tshwj xeeb, kev ua haujlwm, thiab kev ua haujlwm tau zoo. Tias yog vim li cas xaiv txoj cai overload relay yog qhov tseem ceeb rau kev ua kom muaj kev nyab xeeb, tiv thaiv kev poob qis, thiab ua kom lub cev muaj zog.

Schneider Electric txhawb cov txheej txheem no nrog cov ncauj lus kom ntxaws, xws li Schneider overload relay catalog PDF thiab Schneider overload relay ntau hom ntawv xaiv PDF. Cov cuab yeej no pab cov neeg yuav khoom thiab cov kws tsim khoom ua kom zoo sib xws rau cov kev xav tau ntawm lawv daim ntawv thov, txawm tias lawv xaiv cov thermal relays los yog cov kev daws teeb meem zoo tshaj plaws.

Yog vim li cas thiaj xaiv Overload Relay tseem ceeb

Lub overload relay yog thawj kab ntawm kev tiv thaiv ntawm koj lub cev muaj zog thiab kev puas tsuaj. Kev xaiv kom raug muaj ntau yam txiaj ntsig:

• Tiv thaiv Motor Burnout: Overloads yog ib qho ua rau lub cev tsis ua haujlwm. Txoj cai relay mus ncig ua ntej kev puas tsuaj tshwm sim.
• Zam tsis tsim nyog Downtime: Raws li qhov loj me ntawm relays txo qhov tsis txaus ntseeg uas cuam tshuam kev tsim khoom tsis tsim nyog.
• Ua tau raws li cov qauv kev nyab xeeb hluav taws xob: Kev sib koom tes sib txuas raug raug nrog SCPDs (cov khoom siv tiv thaiv luv luv) ua kom muaj kev ua raws NEC/IEC.
• Txhim kho cov cuab yeej siv tau ntev: Kev tiv thaiv raws li lub cev muaj zog Full Load Amps (FLA) txuas lub cev muaj zog kev pab cuam lub neej.

Xaiv qhov tsis ncaj ncees lawm relay, ntawm qhov tod tes, tuaj yeem ua rau lub cev tsis ua haujlwm ntxov ntxov, cov nqi hloov pauv siab, lossis tsis tsim nyog halts hauv kev tsim khoom.

Nkag siab txog Schneider Overload Relay Selection Chart

Schneider cov ncauj lus kom ntxaws overload relay ntau yam xaiv daim ntawv qhia ua rau txoj kev xaiv yooj yim dua. Daim ntawv qhia no teev cov yam ntxwv ntawm lub cev muaj zog, overload relay hom, thiab daim ntawv thov sib raug zoo los pab cov neeg siv kev xaiv raug.

Cov parameter tseem ceeb tshaj plaws hauv daim duab suav nrog:

• Lub cev muaj zog puv Load Amps (FLA): Tus nqi tseem ceeb siv los loj relays kom raug.
• Lub cev muaj zog (HP / kW): Txiav txim siab tshaj kev tiv thaiv overload raws li lub peev xwm thauj khoom.
• Lub cev muaj zog: Xyuas kom cov relay tsim nyog rau kev ntsuam xyuas hauv koj lub cev.
• Trip Class - Schneider relays muaj nyob rau hauv Chav Kawm 10, 20, lossis 30 (lub sijhawm hauv vib nas this mus ncig ntawm 600% ntawm tam sim no).
• Starter Hom: Kev xaiv sib txawv rau Direct-On-Line, Star-Delta, lossis lwm txoj hauv kev pib.
• Hom Relay: Cov kev xaiv muaj xws li thermal (xws li TeSys LRD) rau daim ntawv thov txheem los yog hluav taws xob (zoo li TeSys Giga Kev Tiv Thaiv Relays) rau kev soj ntsuam siab heev.

Cov ntaub ntawv no, nrog rau Schneider overload relay ntau yam xaiv daim ntawv PDF, muab txoj hauv kev rau kev xaiv cov khoom raug.

Kauj ruam-by-step xaiv txheej txheem

Kauj ruam 1: Txiav txim siab lub cev muaj zog puv Load Amps (FLA)

Tshawb xyuas daim ntawv tsav tsheb rau FLA. Schneider's relays yog qhov loj hauv amp ranges, tsis yog horsepower ib leeg. Piv txwv li: 10 HP, 400V lub cev muaj zog yuav muaj ~ 14.8A FLA.

Kauj Ruam 2: Txheeb xyuas cov yam ntxwv ntawm lub cev muaj zog

Nco ntsoov lub cev muaj zog HP / kW ntsuas, kev khiav hauj lwm voltage, thiab daim ntawv thov hom (lub luag hauj lwm tas li, tsis tu ncua, siab pib torque, thiab lwm yam). Cov xwm txheej no txo ​​qis cov kev xaiv.

Kauj ruam 3: Xaiv Relay Hom

Tom ntej no, xaiv los ntawm ob lub relay nram qab no:

• Thermal relays (zoo li cov Schneider LRD overload relays) yog qhov zoo tagnrho rau cov qauv siv uas yooj yim thiab kev ntseeg tau yog qhov tseem ceeb. Cov kev xaiv nrov suav nrog Schneider Electric LRD14 overload relay, ntsuas rau 7-10 A motors.
• Electronic relays (zoo li cov TeSys Giga Kev Tiv Thaiv Relays) xa cov neeg raug siab dua, theem poob rhiab heev, thiab kev kuaj mob nyob deb, ua rau lawv tsim nyog rau cov ntawv thov tseem ceeb.

Kauj Ruam 4: Nrog rau Daim Ntawv Qhia

Thaum koj paub lub cev muaj zog tag nrho load amps (FLA) thiab lwm yam ntsiab lus tseem ceeb, siv Schneider's overload relay xaiv daim ntawv kom phim qhov tseeb relay. Daim ntawv qhia cross-references koj FLA nrog rau qhov tsim nyog relay ntau yam thiab mus txawv tebchaws chav kawm.

Piv txwv li:

• Lub cev muaj zog ntsuas 7-10A feem ntau hu rau Schneider TeSys LRD14 bimetallic overload relay, Chav 20.
• Rau qhov siab dua lossis kev tiv thaiv qib siab, koj tuaj yeem xaiv Schneider LR9D solid-state relay.
• Rau kev tswj lub cev muaj zog, Schneider's TeSys T Motor Management System muab kev saib xyuas, kev sib txuas lus, thiab kev tiv thaiv kev kwv yees.

Kauj ruam 5: Xav txog cov yam ntxwv ntxiv

Niaj hnub nimno relays mus dhau kev tiv thaiv overload. Ntsuas:

• Phase poob thiab theem imbalance rhiab heev.
• Pib dua hom (manual or automatic).
• Cov kev sib txuas lus sib txuas rau kev taw qhia tej thaj chaw deb.
• Integration xaiv nrog starters xws li cov TeSys GV2 lub cev muaj zog pib los yog high-power units zoo li cov TeSys Giga Contactors.

Feem ntau yuam kev kom tsis txhob thaum xaiv

Txawm tias cov neeg yuav khoom muaj peev xwm tuaj yeem ua yuam kev thaum xaiv overload relays. Qee qhov pitfalls muaj xws li:

• Undersizing los yog oversizing lub relay - ob qho tib si ua rau muaj kev tiv thaiv tsis txaus lossis tsis tsim nyog tripping.
• Tsis quav ntsej qhov nyiaj them rau qhov kub thiab txias - relays yuav xav tau kev hloov kho yog tias ntsia rau hauv qhov chaw huab cua.
• Overlooking contactor compatibility - relays yuav tsum ua raws li cov contactor ntau yam los xyuas kom meej seamless kev sib koom tes, xws li LRD relays ua ke nrog TeSys D contactors.
• Hla Kev Mus Ncig Chav Kawm Kev Txiav Txim Siab: Ib chav kawm 10 relay tuaj yeem ua rau muaj kev ntxhov siab-kev mus los ntawm kev ua haujlwm siab-inertia; Chav kawm 20 yog qhov tsim nyog dua.

Zam kev ua yuam kev no ua kom pom kev tiv thaiv lub cev muaj zog thiab kev ntseeg tau ntawm lub cev.
