Thermal Over-load Relay lossis tso tawm

1.thermal overload relay los yog tso tawm

Ib qho relay lossis tso tawm uas ua haujlwm nyob rau hauv lub sijhawm rov qab (suav nrog ncua sijhawm) nyob ntawm cov nyhuv thermal tsim los ntawm qhov tam sim no ntws los ntawm lub relay lossis tso tawm.

2. Electromagnetic overload relay los yog tso magnetic overload relay los yog tso tawm

Ib qho overload relay lossis tso tawm uas ua haujlwm los ntawm kev siv lub zog tsim los ntawm qhov tam sim no ntws los ntawm lub ntsiab Circuit Court thiab txaus siab rau electromagnetic coil.

Lus Cim: Cov khoom siv los yog tso tawm saum toj no feem ntau muaj lub sijhawm hloov pauv / cov yam ntxwv tam sim no.

3. taw tes excitation tso tawm hloov

Ib qho kev tso tawm cov cuab yeej zoo siab los ntawm qhov chaw voltage.

Lus Cim: Qhov hluav taws xob qhov hluav taws xob tej zaum yuav tsis muaj kev ywj pheej ntawm lub ntsiab hluav taws xob hluav taws xob.

4. undervoltage relay los yog tso tawm under-voltage relay los yog tso tawm

Thaum lub davhlau ya nyob twg voltage ntawm ib tug relay los yog tso tawm poob mus rau ib tug predetermined tus nqi, ib tug relay los yog tso tawm uas qhib los yog kaw ib tug neeg kho tshuab hloov nrog los yog tsis ncua.

5.reverse tam sim no relay lossis tso tawm (tsuas yog siv tau rau DC) reveres tam sim no relay lossis tso tawm

Ib tug relay los yog tso tawm nyob rau hauv ib tug DC Circuit Court uas ua rau mechanical switching li disconnect nrog los yog tsis ncua sij hawm thaum cov kev taw qhia ntawm tam sim no hloov thiab tshaj ib tug predetermined tus nqi.

6.(ntawm ib qho dhau tam sim no relay lossis tso tawm) kev khiav hauj lwm tam sim no

Tus nqi tam sim no uas tus relay lossis tso tawm tuaj yeem ua haujlwm tau thaum qhov tam sim no sib npaug lossis ntau dua li tus nqi no.

7. (overcurrent lossis overload relay los yog tso tawm) tam sim no tus nqi teeb tsa

Tus nqi tseem ceeb tam sim no uas muaj feem xyuam rau cov yam ntxwv ntawm kev ua haujlwm ntawm relay lossis tso tawm thiab siv los txiav txim siab qhov kev txiav txim ntawm relay lossis tso tawm.

Nco tseg: Relays lossis tso tawm cov cuab yeej tuaj yeem muaj ntau dua ib qho kev teeb tsa tam sim no, uas tuaj yeem txiav txim siab los ntawm cov dials hloov tau, hloov tau cov cua sov, thiab lwm txoj hauv kev.

8.(rau overcurrent lossis overload relays lossis tso tawm) tam sim no qhov chaw teeb tsa

Qhov ntau ntawm qhov siab tshaj plaws thiab qhov tsawg kawg nkaus ntawm qhov kho tau relay lossis tso tawm tam sim no.
