Tsim Case ntawm 8-Channel AC Input Busbar Txee

1. Lub Hom Phiaj thiab Kev Xav Tau

Tsim ib lub 8-in-1-tawm AC combiner txee. Raws li nws yog ib qhov project off-grid, nws tsuas yog xav tau kev sib txuas ua haujlwm.

Raws li daim duab qhia saum toj no, lub txee specifications yog 3000kVA / 800V. Tag nrho cov tam sim no nkag mus rau hauv lub txee yog: 350kW * 8 / 800V / 1.732 ≈ 2020A. Qhov nruab nrab tam sim no ib ceg yog 253A.

2.Main Equipment xam thiab tsim

Input Moulded Case Circuit Breakers (MCCBs)

Muaj nuj nqis: 8 units, piv rau "8-hauv" topology. Ib tug breaker ib ceg input rau kev tiv thaiv ywj siab, cais tsuas yog faulty ceg tsis muaj kev cuam tshuam rau lwm tus.

Kev ntsuas tam sim no: Tag nrho cov zis tam sim no ~ 2020A. Muab faib sib npaug ntawm 8 ceg muab qhov siab tshaj plaws ntawm ~ 253A ib ceg. A 400A breaker raug xaiv los tiv thaiv kev thauj mus los thaum lub sijhawm ua haujlwm ntev. (Formula: I_total=(P_total) / (√3 * V_LL) )

Ncej: 3P (Peb-theem). Lub hauv paus ntawm lub off-grid AC system yog peb-theem fais fab Circuit Court. Cov kab nruab nrab txuas nrog sib cais ntawm cov khoom siv (tsis tawg los ntawm lub tshuab tawg), ua kom yooj yim tsim thiab ua kom muaj kev tiv thaiv kev ruaj ntseg rau lub ntsiab peb -theem circuit.

Breaking Capacity: Ntau dua lossis sib npaug li 50kA, muaj peev xwm cuam tshuam sai li qhov kwv yees ib zaug - ceg luv - tam sim no (~ 31.5kA) ntawm 800V, tiv thaiv kev puas tsuaj arc thiab ua kom ntseeg tau tias muaj kev sib cais txhaum cai.

Output Ncej Circuit Breaker (FCB)

Quantity: 1 unit, txuam nrog "1-tawm" topology. Ib lub ntsiab breaker tswj cov khoom sib xyaw ua ke los ntawm 8 inputs.

Kev ntsuas tam sim no: Tag nrho tam sim no ~ 2020A. A 4000A thav duab breaker raug xaiv (xav tias tsis yog- tsis tu ncua kev thauj khoom tas mus li thiab rov ua dua hauv cov tsheb npav / cables), txhawb nqa luv luv - lub sijhawm dhau thiab ua tau raws li qhov siab - lub zog tso zis xav tau.

Undervoltage Delay Release: Off-kab kab sib chaws tsis muaj daim phiaj kev txhawb nqa thiab muaj feem cuam tshuam rau qhov hloov pauv voltage. Kev ua haujlwm qeeb tiv thaiv kev cuam tshuam tsis zoo thaum lub sijhawm hloov pauv hloov pauv, ua kom lub zog ruaj khov.

Ncej: 3P, haum rau lub ntsiab peb -theem ua ke busbar. Qhov nruab nrab yog wired ntawm nws tus kheej, tsis dhau los ntawm lub ntsiab breaker, tsom kev tiv thaiv (overload, luv-circuit) ntawm peb-theem lub ntsiab Circuit Court.

Kev Muaj Peev Xwm tawg: Ntau dua lossis sib npaug li 63kA, cuam tshuam qhov kwv yees tag nrho cov tsheb npav luv luv -circuit tam sim no (~ 40kA) nrog kev tawg sai thiab zoo arc tua, tiv thaiv kev ua txhaum loj.

Rotary isolator hloov (kev hloov pauv)

Kev ntsuas tam sim no: Sib phim rau sab tso zis qhov siab tshaj plaws tam sim no ntawm 2020A txhawm rau tiv thaiv cua sov thaum sib cais.

Muaj nuj nqi: Rau kev txij nkawm nyob rau hauv off- kab sib chaws systems, nws muab lub cev, arc- so dawb nyob rau hauv peb lub - theem tseem ceeb Circuit Court, muab ib tug txhim khu kev qha cais ntau tshaj li ib tug breaker rau cov neeg ua hauj lwm kev nyab xeeb.

Ncej: 3P, ib txhij disconnecting tag nrho peb theem ntawm lub ntsiab Circuit Court, txuam lub breaker configuration. Qhov nruab nrab tsis tas yuav tsum muaj kev sib cais (paub tias tuag cais thaum kho), ua haujlwm yooj yim thaum ua raws li cov qauv kev nyab xeeb.

AC Surge Protective Device (SPD)

Kev ntsuas hluav taws xob: Sib phim lub kaw lus 800V AC ntsuas hluav taws xob tiv thaiv SPD tsis ua haujlwm.

Nominal Discharge Tam Sim No (Nyob rau hauv): Tawm- daim phiaj xwm txheej tsis muaj kev sib koom tes tiv thaiv kab hluav taws xob. Nws yuav tsum tau nws tus kheej tiv thaiv xob laim surge voltages. Lub peev xwm 100kA npog qhov yuav tsum tau muaj rau thaj chaw xob laim nruab nrab, nqus hluav taws xob hluav taws xob.

Ncej: 4P (peb -theem + nruab nrab). Txawm hais tias breakers yog 3P, cov kab nruab nrab tseem yuav tsum muaj kev tiv thaiv kev tiv thaiv kom tsis txhob muaj kev puas tsuaj ntawm cov khoom siv hluav taws xob dhau ntawm qhov nruab nrab, muab kev tiv thaiv kev tiv thaiv hluav taws xob.

3. Kev Xaiv Cov Khoom Siv thiab Cov Khoom Siv (BOM)

Raws li cov txheej txheem tshwj xeeb (3000kVA / 800Vac, 8-hauv-1-tawm, 253A ib ceg, 2020A tag nrho), xaiv cov khoom tsim nyog.

Txee Enclosure

Dimensions: Dav 1000mm, Qhov tob 1000mm, Qhov siab 2200mm, Yuav tsum haum 8 input breakers, 1 loj output breaker, busbars, tam sim no transformers, thiab lwm yam. Dav, qhov tob, thiab qhov siab yuav tsum tso cai rau kev tivthaiv layout, txias qhov chaw, thiab cable routing.

Khoom siv: Hlau rau siab mechanical zog, tsis kam mus rau sab nraum zoov ib puag ncig corrosion thiab cuam tshuam, haum rau tej zaum sab nraum installation nyob rau hauv off{0}} kab sib chaws scenarios.

Kev Tiv Thaiv Kev Ntsuas: IP54 rau kev tiv thaiv plua plav thiab dej, tiv thaiv kev nkag mus uas tuaj yeem ua rau siab -voltage shorts, ua kom muaj kev nyab xeeb sab nraum zoov.
