Technical parameters ntawm residual tam sim no Circuit Court breaker

Lub luag haujlwm tseem ceeb ntawm kev ua haujlwm tsis muaj xws li: ntsuas qhov seem seem tam sim no ua haujlwm tam sim no, ntsuas qhov seem seem ntawm lub sijhawm ua haujlwm tam sim no, thiab ntsuas qhov seem seem uas tsis yog{0}} ua haujlwm tam sim no. Lwm yam tsis muaj xws li: fais fab mov zaus, ntsuas voltage, thiab ntsuas tam sim no.

① Rated Residual Current Operating Current: Tus nqi tam sim no uas yuav ua rau cov khoom seem tam sim no (RCD) mus rau hauv cov xwm txheej tshwj xeeb. Piv txwv li, 30mA RCD yuav tawm mus thiab tshem tawm cov khoom siv hluav taws xob thaum siv tam sim no mus txog 30mA.

② Rated Residual Tam Sim No Ua Haujlwm Lub Sijhawm: Lub sijhawm los ntawm kev thov tam sim ntawd ntawm qhov ntsuas qhov seem tam sim no ua haujlwm tam sim no kom txog rau thaum kev tiv thaiv Circuit Court raug txiav. Piv txwv li, ib tug 30mA × 0.1s RCD yuav siv sij hawm tsis ntau tshaj 0.1s los ntawm tam sim no mus txog 30mA kom txog rau thaum lub ntsiab kev sib cuag.

③ Rated Residual Current Non-Operating Current: Tus nqi tam sim no uas RCD yuav tsis mus raws li cov xwm txheej tau teev tseg. Feem ntau, qhov no yuav tsum yog ib nrab ntawm cov seem tam sim no ua haujlwm tam sim no. Piv txwv li, ib qho RCD uas muaj qhov seem ntawm kev ua haujlwm tam sim no ntawm 30mA yuav tsum tsis txhob mus thaum qhov tam sim no nce mus txog 15mA; txwv tsis pub, nws qhov kev hnov ​​​​mob siab tuaj yeem ua rau tsis muaj tseeb, cuam tshuam rau kev ua haujlwm ntawm cov khoom siv hluav taws xob.

④ Lwm qhov tsis zoo, xws li cov khoom siv hluav taws xob, qhov ntsuas hluav taws xob, thiab cov ntsuas tam sim no, yuav tsum tau sib xws nrog cov khoom siv hluav taws xob thiab cov khoom siv hluav taws xob siv thaum xaiv cov khoom siv tam sim no (RCD). RCD qhov kev khiav hauj lwm qhov hluav taws xob yuav tsum tau sib xws nrog cov kev hloov pauv ib txwm muaj ntawm daim phiaj hluav taws xob. Kev hloov pauv ntau dhau yuav cuam tshuam rau kev ua haujlwm ib txwm muaj ntawm RCD, tshwj xeeb tshaj yog rau cov khoom siv hluav taws xob, uas yuav tsis ua haujlwm yog tias lub zog hluav taws xob qis dua RCD qhov ntsuas hluav taws xob ua haujlwm. RCD qhov ntsuas kev khiav hauj lwm tam sim no yuav tsum sib phim qhov tam sim no hauv Circuit Court. Yog tias qhov kev khiav hauj lwm tam sim no tshaj RCD qhov ntsuas tam sim no, nws yuav ua rau overload thiab malfunction.
