Puas yog disconnect keyboards nyob rau hauv ib lub voj voog muaj tam sim no - tawg thiab arc - tua muaj peev xwm?

Cia peb txheeb xyuas kom meej thiab ua kom zoo rau kev tsim thiab kev ua haujlwm ntawm kev sib txuas ntawm cov keyboards ntawm lawv ob lub peev xwm: "tam sim no tawg" thiab "arc extinguishing."

Disconnect keyboards tsis muaj lub ntsiab lus tseem ceeb load tam sim no tawg peev xwm los yog siab arc -extinguishing muaj peev xwm. Kev siv lawv los cuam tshuam kev thauj khoom tam sim no yog kev ua haujlwm tsis zoo uas tuaj yeem ua rau muaj kev puas tsuaj loj.

1. Core Design Lub Hom Phiaj: Kev cais hluav taws xob

Lub luag haujlwm tseem ceeb thiab tseem ceeb ntawm kev hloov pauv yog muab cov huab cua pom thiab txhim khu kev qha - insulated so kom ntseeg tau tias muaj kev sib cais hluav taws xob ua tiav ntawm cov khoom siv hluav taws xob thiab cov khoom siv hluav taws xob thaum tu, ua kom cov neeg ua haujlwm muaj kev nyab xeeb.

• "Visible": Tom qab ua haujlwm, cov neeg sib cuag yuav tsum pom meej ntawm qhov muag liab qab, tsim kom muaj qhov sib txawv.

• "Reliable": Lub rwb thaiv tsev nyob deb ntawm qhov tawg yog txaus los tiv thaiv cov overvoltages nyob rau hauv lub system, kom tsis txhob muaj tam sim no ntws.

2. Hais txog "Interrupting Current Capacity"

• Cov ntsiab lus txhais: "kev cuam tshuam tam sim no muaj peev xwm" ntawm lub npe ntawm cov khoom siv hluav taws xob feem ntau yog hais txog qhov siab tshaj plaws tam sim no (xws li luv luv -circuit tam sim no) lossis ntsuas qhov ntsuas tam sim no uas nws tuaj yeem cuam tshuam kev nyab xeeb.

• Qhov Tseeb Txog "Interrupting Tam Sim No" ntawm Disconnect Switch:

Nws tsis muaj qhov ntsuas load tam sim no cuam tshuam muaj peev xwm. Txhua qhov kev sim siv nws los cuam tshuam cov khoom siv ib txwm muaj (xws li lub cev muaj zog, hloov pauv, teeb pom kev zoo circuits) yuav ua rau muaj zog hluav taws xob arc thaum lub sijhawm qhib, ua rau kev sib cuag melting, theem - mus rau -theem luv circuits, los yog arcing thiab luv luv -circuit explosions.

Qhov tam sim no nws tso cai rau kev khiav lag luam nrog yog txwv rau qhov me me capacitive lossis inductive tam sim no nyob rau hauv tsis muaj -load tej yam kev mob, xws li:

▪ Kev them nqi tam sim no ntawm kev sib txuas ntawm lub tsheb npav tsis tau thauj khoom (hauv ob peb lub amperes).

▪ Disconnecting me me - cov cuab yeej muaj peev xwm xws li voltage transformers thiab surge arresters (feem ntau yuav tsum muaj tam sim no tsawg dua 0.5A).

▪ Kev ua haujlwm hloov pauv hloov pauv (piv txwv li, hloov kev ua haujlwm hauv ob npaug -busbar system, kom ntseeg tau tias txoj kev tam sim no tau raug xa mus rau tib lub sijhawm los ntawm lwm cov keyboards).

Cov kev tso cai ua haujlwm tam sim no yog qhov me me, thiab lawv lub zog arc tuaj yeem raug tua los ntawm huab cua ncab thiab cua txias. Txawm li cas los xij, qhov no tsis txhais hais tias nws muaj qhov tsim "tam sim no- tawg peev xwm."

3. Hais txog "Arc Extinguishing Capability"

• Arc Extinguishing Principple: Yuav kom cuam tshuam tam sim no yam xyuam xim, lub arc generated thaum kev sib cuag yuav tsum tau txias thiab tua sai sai. Circuit Court breakers siv complex arc -tawm chav tsev, siv lub tshuab nqus tsev, SF6 gas rwb thaiv tsev thiab arc tshuab, los yog roj nruab nrab, compressed cua, thiab lwm yam, rau lub zog arc extinguishing.

Lawv cov qauv yog yooj yim heev, feem ntau tsuas yog ib txheej ntawm riam keyboards raug huab cua. Tsis muaj qhov tshwj xeeb arc- cov cuab yeej tua hluav taws (xws li arc- tua cov chav, arc- cov kab hluav taws tua hluav taws, cov cua compressed pistons, thiab lwm yam). Kev sib cais ceev nrawm heev (kev ua haujlwm ntawm tes), uas yog qhov kev txwv loj tshaj plaws hauv arc extinguishing -kev sib cais qeeb yuav tuav tau arc hlawv rau lub sijhawm ntev.

Lub arc generated thaum lub sij hawm cuam tshuam tsuas yog nyob rau hauv tej huab cua convection, thermal buoyancy, thiab electromagnetic quab yuam rau stretching thiab txias. Nws cov arc-extinguishing muaj peev xwm yog qhov tsis muaj zog thiab tsis muaj kev ntseeg siab, tag nrho tsis muaj peev xwm tuav tau cov ntsiab lus tseem ceeb tam sim no.

Kev sib koom tes ua haujlwm nrog Circuit Breakers (Kev Ua Haujlwm Ib Leeg)

Nyob rau hauv lub tshuab fais fab, disconnect keyboards yuav tsum tau siv nyob rau hauv series nrog Circuit Court breakers kom tiav tag nrho cov txheej txheem ntawm "tawg" thiab "kho" lub Circuit Court.

Lawv cov qauv yog yooj yim heev, feem ntau tsuas yog ib txheej ntawm riam keyboards raug huab cua. Tsis muaj qhov tshwj xeeb arc- cov cuab yeej tua hluav taws (xws li arc- tua cov chav, arc- cov kab hluav taws tua hluav taws, cov cua compressed pistons, thiab lwm yam). Kev sib cais ceev nrawm heev (kev ua haujlwm ntawm tes), uas yog qhov kev txwv loj tshaj plaws hauv arc extinguishing -kev sib cais qeeb yuav tuav tau arc hlawv rau lub sijhawm ntev.

Lub arc generated thaum lub sij hawm cuam tshuam tsuas yog nyob rau hauv tej huab cua convection, thermal buoyancy, thiab electromagnetic quab yuam rau stretching thiab txias. Nws cov arc-extinguishing muaj peev xwm yog qhov tsis muaj zog thiab tsis muaj kev ntseeg siab, tag nrho tsis muaj peev xwm tuav tau cov ntsiab lus tseem ceeb tam sim no.

Kev sib koom tes ua haujlwm nrog Circuit Breakers (Kev Ua Haujlwm Ib Leeg)

Nyob rau hauv lub tshuab fais fab, disconnect keyboards yuav tsum tau siv nyob rau hauv series nrog Circuit Court breakers kom tiav tag nrho cov txheej txheem ntawm "tawg" thiab "kho tawm" Circuit Court:

1. Breaking Current: Ua ntej, lub Circuit Court breaker ua haujlwm, txiav tawm tag nrho cov load tam sim no thiab tam sim no txhaum. Lub sijhawm no, tsis muaj tam sim no nyob rau hauv Circuit Court, tab sis cov kev sib txuas ntawm Circuit Court breaker tsis pom lossis tsis ua raws li qhov kev sib cais ntawm kev nyab xeeb.

2. Tsim kev cais tawm: Tom qab paub meej tias lub Circuit Court breaker tau qhib, qhib lub disconnect keyboards ntawm ob sab los tsim ib qho chaw pom thiab muaj kev nyab xeeb hluav taws xob.

3. Kev tiv thaiv hauv av: Yog tias tsim nyog, kaw qhov hloov pauv hauv av (ib qho kev hloov pauv tshwj xeeb) ntawm cov khoom siv tu vaj tse cais tawm kom tso cov nqi seem thiab tiv thaiv kev sib tsoo.

Restore fais fab mov:

1. Tshem tawm hauv av: Tshem tawm qhov hloov hauv av.

2. Tso Cai Tawm Tawm: Kaw qhov kev hloov pauv.

3. Reconnect Circuit Court: Thaum kawg, kaw lub Circuit Court breaker kom rov muab lub hwj chim.

Cov ntsiab lus kawg: Koj tuaj yeem xav txog cov hluav taws xob hluav taws xob raws li 'ntse keyboards' nyob rau hauv ib qho hluav taws xob Circuit Court, lub luag hauj lwm rau kev coj los yog cuam tshuam tam sim no ntws. Disconnectors, txawm li cas los xij, ua haujlwm raws li 'safety blades', muab qhov pom thiab txhim khu kev qha "xauv" tom qab kev txiav tawm kom ntseeg tau tias cov khoom siv hluav taws xob tsis tuaj yeem rov ua dua - lub zog thaum tu. Tsis muaj qhov xwm txheej yuav tsum tau siv 'kev nyab xeeb hniav' los ua lub luag haujlwm ntawm 'ntse hloov'.

VTZ-12 nqus Circuit Court breaker(tshwj xeeb qauv ntawm Tongzhong Hluav taws xob Co., Ltd.) yog ib tug sab hauv tsev switchgear rau rated voltage 12kV, AC 50/60Hz. Nws siv lub tshuab ua haujlwm modular thiab tsim nyog rau ntau yam kev lag luam thiab kev lag luam mining, nrog rau cov khoom siv hluav taws xob. Nws tuaj yeem siv los ua ib lub tawb nqa khoom siv nrog KYN28A-12 switchgear, los yog raws li ib qho chaw ruaj khov nrog cov khoom siv sib cuam tshuam, ua rau nws haum rau XGN2 thiab lwm cov khoom ruaj khov.
