Lub hauv paus ntsiab lus ntawm lub thawv xa khoom
Tso lus
Lub hauv paus ntsiab lus tseem ceeb ntawm lub thawv xa khoom yog faib, tswj, thiab tiv thaiv cov khoom siv hluav taws xob sab nraud ua ntej xa mus rau ntau yam hluav taws xob circuits. Yooj yim muab tso, nws ua raws li "lub zog faib hluav taws xob thiab chaw tswj hwm," faib lub zog loj rau hauv ntau lub voj voog raws li kev xav tau sib txawv thiab ua kom ntseeg tau tias txhua lub voj voog ua haujlwm tsis pub dhau kev txwv.
Raws li txoj cai, lub thawv xa khoom feem ntau muaj cov khoom siv hluav taws xob, cov khoom siv tam sim no (RCDs), fuses, contactors, thiab busbars. Tam sim no nkag los ntawm lub input davhlau ya nyob twg, thawj zaug dhau los ntawm lub ntsiab hloov thiab kev tiv thaiv pab kiag li lawm, thiab ces muab faib mus rau ntau yam ceg circuits ntawm lub busbars. Txhua ceg Circuit Court muaj kev ywj pheej hloov tswj; Yog hais tias ib qho overload, luv luv Circuit Court, los yog leakage tshwm sim nyob rau hauv ib lub voj voog, cov cuab yeej tiv thaiv yuav txiav tawm qhov Circuit Court yam tsis muaj kev cuam tshuam rau lwm yam circuits.
Cov txheej txheem tiv thaiv yog ib qho ntawm cov ntsiab cai tseem ceeb ntawm lub thawv xa khoom. Cov kab hluav taws xob hluav taws xob kuaj xyuas qhov txawv txav los ntawm kev ntsuas qhov ntsuas tam sim no, thaum RCDs saib xyuas qhov sib txawv tam sim no ntawm cov xov hlau nyob thiab nruab nrab. Thaum cov dej xau lossis qhov txawv txav tshwm sim, lub kaw lus yuav txiav tawm lub zog hluav taws xob hauv lub sijhawm luv luv, yog li tiv thaiv cov khoom puas lossis hluav taws xob poob. Lub hwj chim ceev no -off mechanism yog qhov tseem ceeb ntawm kev ruaj ntseg hluav taws xob.
Los ntawm kev xav txog kev ua haujlwm, lub thawv xa khoom yog lub luag haujlwm rau ob qho tib si "kev faib hluav taws xob hluav taws xob" thiab "kev tswj hwm kev pheej hmoo." Nws tso cai rau hluav taws xob xa mus rau cov khoom sib txawv xws li teeb pom kev zoo, lub qhov (socket), lub tshuab cua txias, lossis cov khoom lag luam raws li xav tau, thaum tseem cais cov kev ua txhaum los ntawm kev tiv thaiv tied, ua rau tag nrho lub zog hluav taws xob ruaj khov, nyab xeeb, thiab tswj tau.
