MCCB oo leh Ilaalinta Leakage

Kobcinta badbaadada korantada ee dhaafsiisan culeyska iyo ilaalinta wareegga gaaban ee CDADA DAM1L Taxanaha MCCB oo leh Ilaalinta Leakage-ka-jabiye kiis isku dhafan oo isku dhafan oo leh shaqeynta hadda jirta (RCD/ELCB). Naqshadeeyey soo saaraha xirfadleyda ah ee Shanghai DADA Electric CO., LTD ee heerarka caalamiga ah, daadintan MCCB 4P waxay isku daraysaa qaybinta awoodda wax-qabadka sare leh iyo ogaanshaha khaladka dhulka ee dabka-badbaadinta.

Lagu qiimeeyay 10A ilaa 500A ee 400V/415V, waxa ay bixisa hadhaaga hawleed la hagaajin karo (30mA–1000mA) iyo wakhtiga ikhtiyaarka ah ee daahitaanka—oo awood u siinaya ilaalinta ku haboon badbaadada shakhsi ahaaneed (≤30mA) ama ka hortagga dabka (100mA-500mA+). Qalabka elektaroonigga ah ee wajiyo badan leh, way sii shaqaynaysaa xitaa haddii hal waji fashilmo ama korontadu hoos ugu dhacdo 50V, iyada oo hubinaysa isku halaynta aan la isku halayn karin ee kaabayaasha muhiimka ah sida tunnelyada, meelaha dhaadheer, xarumaha gaadiidka, iyo dhirta warshadaha.

Waa maxay sababta ay u dooratay CDADA MCCB oo leh Ilaalinta Leakage?

★ Badbaadada Midaysan ee Runta ah

Si ka duwan cutubyada RCD-da-ku-darka ah, DAM1L waxa ay dhistay, ilaalinta daadinta warshadaysan oo-siisay hubinta isku-duwidda saxda ah iyo tirtiridda arrimaha iswaafajinta.

★ Awoodda Wajiyada Badan ee Wareega RCD

RCD-yadii hore way fashilmeen haddii hal waji la waayo. Nakhshadeynta CDADA waxay isticmaashaa dhammaan wejiyada si ay u xoojiso qalabka elektaroonigga ah ee ilaalinta, si ay u sii shaqeyso xitaa inta lagu jiro marxaladda luminta ama koronto yaraan daran.

★ Ujeedooyinka Ilaalinta Laba-geesoodka ah ee Hal Qalab

◆ 30mA: Buuxiyay shuruudaha IEC ee ilaalinta naxdinta shakhsi ahaaneed

◆ 100mA–1000mA: Waxay ka hortagtaa nabaad-guurka dabka ee ka yimaada cilladaha dhulka yaryar ee joogtada ah.

★ Goobta- Lagu Hagaajin Karo Xaaladaha Dunida Dhabta ah

Dareemi hab-wanaagsan iyo dib-u-dhac waqti si looga fogaado khalkhal xumida deegaanka qoyan (tusaale, baabuurta dhaqida, beeraha) iyadoo la ilaalinayo amniga.

★ Isku hallaynta Fasalka Warshadaha

Awood jabinta sare (nooca H), kala soocida arc adag, iyo IP20+ ilaalinta terminaalka ayaa ka dhigaya mid ku habboon goobaha ganacsiga iyo warshadaha adag.

★ U Hogaansanaanta Caalamiga ah, Qiimaha Maxaliga ah

Loo aqoonsaday Yurub (CE/CB), wadamada Waqooyiga Yurub (SEMKO) -ku habboon mashaariicda dhoofinta - oo leh qiime tartan ah oo ka yimid soo-saare shiinees ah oo la aamini karo.

★ Xaruntayada wax soo saarka waxa lagu shahaadeeyay ISO9001:2015 Nidaamka Maareynta Tayada.

FAQ

Q1: Waa maxay faraqa u dhexeeya heerka caadiga ah ee MCCB iyo MCCB ee leh ilaalinta daadashada?

A1: Heerka MCCB wuxuu kaliya ka ilaaliyaa culeyska xad dhaafka ah iyo wareegyada gaaban. DAM1L waxay ku darsataa hadhaaga hadda (dhaleecada dhulka) ogaanshaha-jilicda marka uu hadda dhulka ku soo daadanayo (tusaale, iyada oo qof ama dahaarka dhaawacan), ka hortagga shoog koronto ama dab.

Q2: Ma u isticmaali karaa 100A MCCB RCD ilaalinta shakhsi ahaaneed?

A2: Kaliya haddii lagu dhigo 30mA. Hadda la qiimeeyay (100A) ayaa qeexaysa awoodda culeyska; goobta hadhaaga ah (I△n) ayaa qeexaysa shaqada badbaadada. Ilaalinta shoogga, I△n waa in uu ahaado ≤30mA, iyada oo aan loo eegin In.

Q3: Waa maxay sababta wareegga RCD ugu baahan yahay awood wajiyo badan?

J3: Haddii lagu xoojiyo hal waji, guuldarada hal-waji waxay curyaami doontaa ilaalinta daadinta. Naqshadaynta wejiyada badan ee CDADA waxay hubisaa in RCD uu sii ahaado mid firfircoon xitaa inta lagu jiro wejiga luminta ama korontadu hooseyso (hoos 50V) — oo muhiim u ah sii wadida badbaadada.

Q4: daadinta 4P MCCB ma ku haboon yahay nidaamyada TT ama TN-S?

A4: Haa-waxaa loogu talagalay nidaamyada TT, TN-S, iyo IT. Naqshadeynta 4P waxay jebisaa dhammaan wejiyada oo dhexdhexaad ah, oo lagama maarmaan u ah nidaamyada TT halkaas oo dhexdhexaadku aanu ahayn mid la isku halleyn karo.

Q5: Maxaad CDADA uga doorataa isku-darka RCD + MCCB?

A5: CDADA DAM1L waxay bixisaa:

● Raad yar (isku-dhafan vs. laba qalab)

● Isku-dubbarid la dammaanad qaaday (ma jirto khatar isku mid ah)

● Qiimaha hoose iyo kakanaanta fiilooyinka

● Isku halaynta sare (hal shaabadaysan)

● Laqabsiga goobta oo aan suurtagal ahayn RCD-yada xasaasiga ah
