Dab tsi yog cov khoom siv hluav taws xob ncig? (Ii)

5. Tshuaj Tiv Thaiv

Ua haujlwm ua haujlwm:Tshawb nrhiav qhov sib txawv tam sim no ntawm cov xaim hlau nyob thiab cov hlau nruab nrab hauv Circuital. Nyob rau hauv ib txwm muaj xwm txheej, tam sim no ntws mus rau hauv cov hlau nyob tau sib npaug nrog txoj kev tam sim no ntws tawm ntawm cov xaim nruab nrab. Thaum to zog tshwm sim (xws li hluav taws xob rau tib neeg lub cev lossis cov lag luam hluav taws xob yuav tau txiav ntau dua ntawm cov neeg muaj tus nqi tiv thaiv tus kheej.
Daim Ntawv Thov:Nws yog qhov tsis tseem ceeb nyob rau hauv cov chaw uas hluav taws xob hluav taws xob yog nquag tshwm sim, xws li chav dej, cov chaw pw, thiab lwm yam, cov neeg tiv thaiv kab mob tseem ceeb.

6. Theem Kev Tiv Thaiv Kev Tiv Thaiv

Ua haujlwm ua haujlwm:Txiav txim siab seb puas muaj theem poob los ntawm kev saib xyuas cov voltage lossis tam sim no ntawm ib theem ntawm peb-theem fais fab mov nyob rau hauv lub voj voog.

7. Thermal relay

Ua haujlwm ua haujlwm:Ua haujlwm ntawm lub hauv paus ntsiab lus ntawm thermal nyhuv ntawm tam sim no. Thaum cov tam sim no nyob rau hauv Circuit Court tshaj li qhov rated tam sim no ntawm lub thermal relay yuav kub tawm, ua rau lub bimetallic sawb mus rau khoov vim kub. Thaum cov qib khoov mus txog ib qho nqi, tus tripping mechanism yog tsim los ua haujlwm thiab txiav tawm ntawm Circuit Court. Lub thermal relay muaj qee lub sijhawm Inverse tus yam ntxwv, uas yog, qhov loj dua tam sim no, cov luv luv lub sijhawm txiav txim.
Daim Ntawv Thov:Feem ntau siv rau kev tiv thaiv kev tiv thaiv ntau dhau ntawm lub motors. Piv txwv li, hauv kev tswj lub cev muaj zog ntawm ntau cov cuab yeej siv khoom lag luam tsim khoom lag luam feem ntau yog ntsia kom tiv thaiv cov neeg muaj zog los ntawm kev kub ntxhov. Ib qho ntxiv, rau qee cov kev sib txuas ua haujlwm thiab cov thauj khoom loj hloov cov khoom siv, thermal tawg kuj tseem tuaj yeem ua txoj haujlwm tiv thaiv zoo.

8. Overcurrent relay

Ua haujlwm ua haujlwm:Tus txheej txheem ua haujlwm ntawm overcurrent relay yog raws ntawm cov hauv paus ntsiab lus ntawm induction induction. Thaum qhov tam sim no nyob rau hauv Circuit Court ntau dua li cov teeb tsa tus nqi, lub sib nqus kev sib tw tsim nyob rau hauv cov kev sib tw ua haujlwm, yog li txiav tawm ntawm Circuit Court lossis xa daim teeb liab lossis xa daim teeb liab. Cov kev ua haujlwm tam sim no ntawm overcurrent repay tuaj yeem hloov kho raws li xav tau.
Daim Ntawv Thov:Siv nyob rau hauv circuits nrog cov high kev tiv thaiv rau kev tiv thaiv tam sim no, thiab kev tiv thaiv ntawm cov tshuab hluav taws xob loj, cov hluav taws xob hluav taws xob thiab lwm yam khoom siv hauv kev lag luam. Nws tuaj yeem txiav tawm sai dua ntawm Circuit Court thaum lub Circuit Court yog overloaded lossis luv-circherited los tiv thaiv cov khoom puas thiab kev nthuav dav ntawm cov xwm txheej.

9. Lub cev muaj zog tiv thaiv

Ua haujlwm ua haujlwm:Tus txheej txheem ua haujlwm ntawm lub cev muaj zog tiv thaiv feem ntau yog raws li kev saib xyuas lub cev muaj zog, ntsuas lub cev muaj zog tam sim no, ntsuas thiab lwm yam kev ntsuas. Thaum cov ntsiab lus no tau tshaj li cov teeb meem kev nyab xeeb, tus tiv thaiv yuav tau lub tswb lossis txiav tawm lub cev muaj zog los tiv thaiv lub cev muaj zog vim kev ua haujlwm tsis raug.
Daim Ntawv Thov:Lub cev muaj zog tiv thaiv tau siv dav hauv ntau cov tsiaj txhu, hluav taws xob muaj kev nyab xeeb thiab lwm yam yog qhov tseem ceeb rau kev txuas ntxiv thiab ua haujlwm ntawm cov kab ntau lawm.
