Tam sim no Sensors

A Tam sim no Sensor yog ib qho khoom siv hluav taws xob tsim los ntsuas thiab saib xyuas cov hluav taws xob tam sim no los ntawm lub voj voog. Cov sensors no ua lub luag haujlwm tseem ceeb hauv ntau yam kev siv, muab cov ntaub ntawv tseem ceeb rau kev saib xyuas kev siv hluav taws xob, ua kom cov cuab yeej muaj kev nyab xeeb, thiab ua kom lub zog ua haujlwm zoo. Tam sim no sensors muaj nyob rau hauv ntau hom, txhua catering rau cov kev xav tau tshwj xeeb thiab cov qauv kev khiav hauj lwm.

1. Hall Effect Tam Sim No Sensors: Cov sensors no ua haujlwm ntawm lub hauv paus ntsiab lus ntawm Hall Effect, qhov chaw sib nqus cuam tshuam rau kev txav ntawm cov khoom thauj hauv tus neeg xyuas pib. Raws li tam sim no ntws los ntawm tus neeg xyuas pib, nws tsim ib qho chaw sib nqus, thiab Hall Effect sensor pom qhov tshwm sim ntawm qhov hluav taws xob thoob plaws tus neeg xyuas pib, muab cov txiaj ntsig sib npaug.
2. Rogowski Coil Current Sensors: Rogowski coils yog hloov tau yooj yim coils qhov txhab nyob ib ncig ntawm tus neeg xyuas pib los ntawm qhov tam sim no ntws. Cov coils no tsis muaj cov tub ntxhais sib nqus, ua rau lawv tsim nyog rau kev ntsuas hloov tam sim no (AC). Qhov hloov magnetic teb induces ib tug voltage nyob rau hauv lub kauj, thiab lub sensor ntsuas qhov voltage los txiav txim qhov tam sim no.
3. Kaw-Loop Hall Effect Sensors: Nyob rau hauv kaw-voj Hall Effect sensors, lub tswv yim tawm tswv yim yog ua haujlwm los tswj cov magnetic teb nyob rau theem tas li. Cov sensors paub txog lawv qhov tseeb thiab qhov tseeb, ua rau lawv haum rau cov ntawv thov uas yuav tsum tau ntsuas tam sim no.
4. Tam sim no Transformer (CT): Lub transformer tam sim no yog ib hom sensor uas siv cov hlau nplaum sib nqus los ua kom muaj qhov hluav taws xob nyob rau hauv ib qho kev sib hloov winding proportional rau cov tam sim no ntws los ntawm thawj winding. Tam sim no transformers feem ntau yog siv los ntsuas qhov siab tam sim no hauv cov tshuab hluav taws xob.
5. Shunt Resistor Tam sim no Sensors: Shunt resistors yog muab tso rau hauv series nrog lub load, thiab qhov voltage poob hla tus resistor yog proportional rau tam sim no. Los ntawm kev ntsuas qhov voltage, qhov tam sim no ntws los ntawm Circuit Court tuaj yeem txiav txim siab. Shunt resistor tam sim no sensors feem ntau yog siv rau hauv cov ntawv thov tam sim no.

Daim ntaub ntawv: Tam sim no cov sensors pom cov ntawv thov hauv ntau qhov chaw, suav nrog kev saib xyuas hluav taws xob, kev siv hluav taws xob txuas ntxiv, hluav taws xob tsheb, kev lag luam automation, thiab hluav taws xob circuits. Lawv yog qhov tseem ceeb rau kev ua kom muaj kev ua haujlwm zoo ntawm cov tshuab hluav taws xob, tiv thaiv overloads, thiab ua kom muaj kev tswj xyuas lub zog kom raug.
