Cov Khoom Siv Tiv Thaiv Surge (SPD): Kev Tiv Thaiv Tseem Ceeb Rau Cov Tshuab Hluav Taws Xob Niaj Hnub Nim No

Hauv lub ntiaj teb niaj hnub no uas muaj hluav taws xob ntau zuj zus thiab sib txuas lus, cov kab ke hluav taws xob yeej ib txwm raug kev pheej hmoo xws lixob laim ntaus, hloov pauv surges, thiab transient overvoltagesCov hluav taws xob nce siab sai sai no tuaj yeem ua rau muaj kev puas tsuaj loj rau cov khoom siv hluav taws xob, cuam tshuam kev ua haujlwm, thiab ua rau lub sijhawm tsis ua haujlwm kim heev. Qhov no yog qhov uasCov Khoom Siv Tiv Thaiv Surge (SPD)ua lub luag haujlwm tseem ceeb.

SPD yog dab tsi?

A Cov Khoom Siv Tiv Thaiv Surge (SPD)yog tsim los rautiv thaiv cov kab ke hluav taws xob thiab cov khoom siv los ntawm kev hloov pauv hluav taws xob ib ntuslos ntawm kev xa cov hluav taws xob ntau dhau mus rau hauv av kom muaj kev nyab xeeb. Thaum muaj hluav taws xob ntau dhau, SPD teb tam sim ntawd, txwv qhov hluav taws xob kom nyob rau theem nyab xeeb thiab tiv thaiv kev puas tsuaj rau cov khoom siv txuas nrog.

Vim li cas SPDs thiaj tseem ceeb?

SPDs yog qhov tseem ceeb rau kev ua kom ntseeg tau tias:

• Kev Tiv Thaiv Khoom SivKev tiv thaiv cov khoom siv hluav taws xob thiab khoom siv hluav taws xob rhiab heev ntawm qhov hluav taws xob nce siab
• Kev Ntseeg Siab ntawm Lub SystemTxo lub sijhawm tsis ua haujlwm uas tshwm sim los ntawm kev ua haujlwm tsis zoo uas cuam tshuam nrog kev nce siab
• Kev Ruaj NtsegTiv thaiv kom tsis txhob muaj tej yam txaus ntshai xws li kev puas tsuaj ntawm cov khoom rwb thaiv tsev lossis kev pheej hmoo hluav taws
• Kev Siv Nyiaj ZooTxo cov nqi kho thiab hloov pauv

Nrog lub sijhawm teb ntsuas hauvnanoseconds, SPDs ua haujlwm ua ib txoj kab tiv thaiv ceev thiab txhim khu kev qha rau cov kab ke hluav taws xob.

Cov Xwm Txheej Ib Txwm Muaj Rau Daim Ntawv Thov

SPDs siv dav dav thoob plaws ntau yam lag luam thiab ib puag ncig, suav nrog:

• Cov chaw ua lag luam thiab cov chaw tsim khoom
• Cov tsev lag luam thiab cov chaw ua haujlwm
• Cov tshuab hluav taws xob hauv tsev
• Cov chaw khaws ntaub ntawv thiab cov txheej txheem sib txuas lus
• Cov tshuab hluav taws xob rov ua dua tshiab xws li kev teeb tsa hnub ci (PV)
• Cov tes hauj lwm faib hluav taws xob

Ob leegCov tshuab AC thiab DCxav tau kev tiv thaiv hluav taws xob, tshwj xeeb tshaj yog nyob rau hauv cov chaw uas raug xob laim lossis kev ua haujlwm hloov pauv ntau zaus.

Mutai Electric SPD Solutions

Ua ib lub chaw tsim khoom siv hluav taws xob tsawg,Mutai Electric Groupmuaj ntau yam tiav ntawmCov Khoom Siv Tiv Thaiv Hluav Taws Xob AC thiab DC, tsim los xa kev tiv thaiv txhim khu kev qha thiab ua haujlwm tau zoo rau ntau yam kev siv.

AC SPD Series

Mutai'sAC SPDcov khoom tsim nyog rau220V/380V cov tshuab, muab kev tiv thaiv zoo tiv thaiv cov hluav taws xob surge uas tshwm sim los ntawm xob laim lossis kev cuam tshuam ntawm lub grid.

Cov yam ntxwv tseem ceeb muaj xws li:

• Qhov siab tshaj plaws tam sim no (Imax)mus txog rau100kA (8/20μs)
• Nominal tawm tam sim no (Hauv)mus txog rau60kA (8/20μs)
• Qib kev tiv thaiv qis (Saum toj)los ntawm1.5kV txog 2.5kV
• Lub sijhawm teb saitsawg dua20ns
• Tam sim no xau qisrau kev ruaj khov ntawm lub cev

Cov SPDs no zoo tagnrho rau kev tiv thaivcov vaj huam sib luag faib khoom, cov txee hluav taws xob, thiab cov tshuab hluav taws xob hauv tsev.

DC SPD Series

Mutai'sDC SPDcov khoom lag luam tau tsim tshwj xeeb rauCov tshuab DC, tshwj xeeb tshaj yog nyob rau hauvdaim ntawv thov photovoltaic (PV) hnub cithiab lwm yam kev siv hluav taws xob rov ua dua tshiab.

Cov yam ntxwv tseem ceeb muaj xws li:

• Qhov siab tshaj plaws ntawm kev ua haujlwm tas mus li (Uc)mus txog rauDC1500V
• Nominal tawm tam sim no (Hauv) of 20kA (8/20μs)
• Qhov siab tshaj plaws tam sim no (Imax) of 40kA (8/20μs)
• Qib Kev Tiv Thaiv (Saum Toj)≤3.2kV
• Lub sijhawm teb sai heev of 25ns
• Sib xws nrogKev teeb tsa DIN railrau kev sib koom ua ke yooj yim

Cov khoom siv no tiv thaiv tau zooCov tshuab PV, cov tshuab faib hluav taws xob DC, thiab kev teeb tsa cia hluav taws xoblos ntawm cov surges ib ntus.

Kev Tiv Thaiv Txhim Khu Kev Ntseeg Siab Uas Koj Ntseeg Tau

Nrog kev tsim qauv siab heev, cov khoom zoo, thiab cov qauv tsim khoom nruj, Mutai Electric cov khoom SPD muabkev ua haujlwm ruaj khov, teb sai, thiab kev ntseeg siab mus sij hawm ntevTxawm nyob rau hauv ib puag ncig kev lag luam lossis cov tshuab hluav taws xob rov ua dua tshiab, peb cov SPDs pab ua kom ntseeg tau tiaskev ua haujlwm tas mus li thiab kev nyab xeeb ntawm cov khoom siv.
