Peb -theem seem kev tiv thaiv tam sim no, tseem hu ua peb- theem kev tiv thaiv tam sim no, yog ib qho kev nyab xeeb ntau heev nyob rau hauv Suav teb qis -voltage fais fab faib tshuab (tshwj xeeb tshaj yog nyob rau hauv cov hluav taws xob nyob deb nroog, cov chaw tsim kho, thiab kev kho dua tshiab ntawm thaj chaw qub). Nws lub hauv paus ntsiab lus tseem ceeb yog: kev teeb tsa kev sib koom ua ke, kev sib koom ua ke, tsuas yog qhov ua txhaum ntawm lub ntsiab lus, tsis yog lub ntsiab lus tseem ceeb.
kev ua haujlwm ntawm peb -theem residual tiv thaiv tam sim no
1️⃣ Kev Tiv Thaiv Tseem Ceeb (Lub Ntsiab Hloov) - Kev Tiv Thaiv Hluav Taws Xob, Tiv Thaiv Kev Mus Los Cascading
Nruab rau ntawm transformer outgoing kab los yog lub ntsiab switchboard
Kev ua haujlwm siab tam sim no (300-500mA), tso cai rau lub sijhawm ncua sijhawm
Lub hom phiaj: Nws tsis mus txawv tebchaws thaum muaj qhov xau thaum kawg, tsuas yog qhov kev mus ncig hauv qab; nws tsuas yog mus ncig thaum kawg Circuit Court tsis mus los yog qhov txhaum loj heev.
2️⃣ Kev Tiv Thaiv Thib Ob (Branch Circuit) - Tiv thaiv hluav taws xob sib cuam tshuam, xaiv xaiv
Muab tso rau hauv lub thawv faib khoom, hauv pem teb faib lub thawv
Nruab nrab ua haujlwm tam sim no (100-300mA)
Lub Hom Phiaj: Thaum ib ceg txuas txuas tam sim no, tsuas yog cov ceg mus ncig, tsis muaj kev cuam tshuam rau lwm cov circuits.
3️⃣ Kev Tiv Thaiv Tertiary (End Circuit) - Kev Tiv Thaiv Lub Neej
Muab tso rau hauv lub qhov (socket circuits), cov cuab yeej siv hluav taws xob, khoom siv hluav taws xob ib ntus
Ua haujlwm tam sim no Tsawg dua lossis sib npaug li 30mA
Lub sijhawm ua haujlwm tsawg dua lossis sib npaug ntawm 0.1s, tiv thaiv hluav taws xob ncaj qha.
Daim ntawv thov ntawm peb- theem kev tiv thaiv tam sim no
Scenario Requirements: Kev kho vaj tse nyob deb nroog, lub teb chaws tus qauv GB Standard 50052–95 qhia meej tias yuav tsum tau siv peb- qib tiv thaiv.
Rau cov khoom siv hluav taws xob ib ntus ntawm qhov chaw tsim kho, JGJ 46-2005 yuav tsum muaj qhov hluav taws xob davhlau ya nyob twg tsawg dua lossis sib npaug li 30mA, nrog kev teeb tsa theem.
Rau kev kho dua tshiab ntawm thaj chaw qub, txhawm rau tiv thaiv kev tsis sib haum xeeb, peb- qib kev tiv thaiv feem ntau yog siv.
Rau cov tsev kawm ntawv, tsev kho mob, thiab cov khw muag khoom, qhov hluav taws xob davhlau ya nyob twg yuav tsum tsawg dua lossis sib npaug li 30mA, nrog rau tag nrho cov kab hluav taws xob ntawm 300-500mA.
Khoom Description
GCS tsis tshua muaj hluav taws xob rho tawm switchgear yog tsim rau cov chaw tsim hluav taws xob, kev lag luam petrochemical, metallurgy, textile, siab - nce lub tsev fais fab mov thiab lwm yam lag luam.
Nws yog siv nyob rau hauv loj fais fab nroj tsuag, petrochemical kev lag luam thiab lwm qhov chaw nrog high℃ntawm automation thiab yuav tsum tau rau lub computer interface, raws li kev faib ntawm lub hwj chim nyob rau hauv peb -theem AC zaus 50Hz (60Hz), rated ua hauj lwm voltage 380V (660V), ntsuas tam sim no 4000A thiab cov nram qab no lub zog tsim thiab lub zog mov system,
Nws yog qhov tsawg-voltage ua tiav lub zog faib khoom siv rau kev tswj hwm lub hauv paus ntawm lub tshuab hluav taws xob, kev txwv tam sim no ntawm reactor thiab reactive zog them.
