Tshem tawm fuse
Hauv kev faib hluav taws xob, lub fuse txiav tawm lossis txiav tawm - tawm fuse yog kev sib xyaw ntawm lub fuse thiab qhov hloov pauv, siv nyob rau hauv thawj cov khoom siv hluav taws xob thiab cov kais dej los tiv thaiv cov khoom siv hluav taws xob los ntawm cov hluav taws xob tam sim no thiab overloads. Ib qho overcurrent tshwm sim los ntawm kev ua txhaum ntawm lub transformer los yog cov neeg siv khoom Circuit Court yuav ua rau lub fuse yaj, disconnecting transformer ntawm kab. Nws tseem tuaj yeem qhib tau manually los ntawm cov khoom siv hluav taws xob sawv hauv av thiab siv lub pas nrig ntev hu ua "kub stick".
Kev txiav tawm muaj peb yam tseem ceeb:
Lub cev txiav tawm, qhib "C"- zoo li tus ncej uas txhawb nqa lub fuse tuav thiab lub ribbed plooj (porcelain) lossis polymer insulator uas hluav taws xob cais cov khoom siv hluav taws xob ntawm lub rooj sib txoos los ntawm kev txhawb nqa uas lub insulator yog fastened.
Lub fuse tuav, tseem hu ua "fuse tube" lossis "qhov rooj", lub raj insulating uas muaj cov fuse hloov tau. Thaum muaj cov fuse ua haujlwm ("blows"), lub fuse tuav tawm ntawm sab sauv, tawg lub voj voog, thiab dai ntawm pob khawm ntawm nws qis kawg. Lub fuse tuav no muab ib qho kev qhia pom tias lub fuse tau ua haujlwm thiab paub tseeb tias lub Circuit Court qhib. Lub Circuit Court kuj tseem tuaj yeem qhib tau manually los ntawm rub tawm lub fuse tuav siv lub pas kub.
Cov khoom siv fuse, lossis "fuse txuas", yog qhov hloov pauv tau ntawm lub rooj sib txoos uas ua haujlwm thaum cov hluav taws xob tam sim no zoo txaus.
