Ib qho kev tiv thaiv uas haum Surge (SPD) yog ib txoj haujlwm tseem ceeb uas cuam tshuam nrog kev nyab xeeb ntawm cov khoom siv hluav taws xob. Nws cov tub ntxhais yog ua raws txoj cai ntawm graded tiv thaiv thiab phim cov ntsuas tseem ceeb raws li qhov chaw teeb tsa, kev tiv thaiv kev tiv thaiv, thiab cov kab ke.
Hauv qab no, Kuv yuav siv lub rooj los piav cov kauj ruam tseem ceeb rau xaiv cov kws tiv thaiv cov kev tiv thaiv ncaj qha, thiab tom qab ntawv piav qhia lawv.

Cov Lus Qhia Thov thiab Cov Txheej Txheem |
|
Txiav txim siab txog qib kev tiv thaiv (hom) |
Hom 1 (T1, Qib 1): Yuav kom cuam tshuam nrog lub zog ncaj qha, tso tawm cov khoom siv hluav taws xob loj (I} feem ntau yog nruab rau sab xub ntiag ntawm ntaus ntawv.
|
Graded Configuration: Hom 1 rau cov cim tseem ceeb, ntaus 2 rau lub thawv faib khoom, thiab ntaus 3 rau sab xub ntiag ntawm cov khoom siv precision. Rau cov chaw nyob ib puag ncig lossis qis {{{}}} Txoj Kev pheej hmoo txaus ntshai, ntaus 2 yog OK. |

2. Cov hluav taws xob hluav taws xob tseem ceeb |
Maximum continuous operating voltage (Uc): It must be higher than the maximum normal operating voltage that the line may experience, taking into account factors such as harmonics. -Voltage protection level (Up): The residual voltage appearing at both ends of the equipment after the PD action must be lower than the withstand voltage value of the protected equipment. -Current carrying capacity(Iimp/In/Imax): reflects the Muaj peev xwm ntawm SPD rau kev tso tawm tawm tam sim no, uas yuav tsum tau raug xaiv raws li kev teeb tsa qhov chaw nyob thiab muaj kev pheej hmoo teeb meem |
UC: Hauv 220 / 380V tshuab, UC Ntau dua lossis sib npaug}}} kv {. - muaj peev xwm tam sim no: iimp rau hom 1 yog pom zoo kom muaj ntau dua los yog sib luag rau 12,5 Ka; Hauv Hom 2 pom zoo kom muaj ntau dua lossis sib npaug rau 20 Ka. |

3.System ob tog thiab installation |
Kev tiv thaiv hom: Xaiv raws li lub zog tiv thaiv: Los tiv thaiv kev tiv thaiv luv luv (scb nruab . -}}} installation້ນ}} installation installation and້ນ}::: Cov hlau hauv av yuav tsum yog luv li sai tau (pom zoo kom txo cov khoom hluav taws xob txo qis |
Pole number: TN-S three-phase system commonly adopts the 4P products; TT system pom zoo xaiv cov khoom lag luam nrog n}}} PE tiv thaiv Module: Qhov tshwj xeeb rated module: Qhov tshwj xeeb rated cov kev pom zoo ntawm SPD cov chaw tsim tshuaj paus. |
Xaiv raws li daim ntawv thov cov xwm txheej
Kev tiv thaiv kev tiv thaiv sib txawv hauv cov chaw sib txawv, thiab koj tuaj yeem xa mus rau cov lus qhia hauv qab no rau kev txiav txim siab ua ntej:
· Lub cev muab fais fab thiab xa tawm
· Lub ntsiab lus faib tawm: nruab hom 1 SPD, pom zoo impluse tam sim no i_ kos {{v.
· Rauv hluav taws xob hluav taws xob: nruab hom 2 SPD, pom zoo hu rau nomoginal tawm tam sim no hauv ntau dua lossis sib npaug los yog sib luag rau 1.5 kV ~ 2.0 kV.
· Kev siv cov khoom siv / chav kho computer: Hauv cov ntaub ntawv plc, nruab hom 3 spd nyob rau sab xub ntiag {1} {1} {1}-
· Muaj Automation
· Ntxiv rau kev tiv thaiv lub zog tiv thaiv txhua qib, muaj cov cim qhia txog kev tua kab mob siab rau cov teeb liab thiab cov ntaub ntawv (xws li RS485, Ethernet). Nws UC thiab nce ntxiv kom phim qib teeb liab.
· Photostroltai thiab lwm lub zog tshiab
· DC sab (xws li Comminer Box, Inverter DC Kawg): thiab nws UC yuav tsum hloov mus rau ntau dua DC kev tiv thaiv hluav taws xob (xws li 1000V lossis 1500v).
· Kev sib txuas lus: Cov ntsiab cai tiv thaiv yog tib yam li cov pa hluav taws xob.
Cov ntsiab lus tseem ceeb rau kev teeb tsa thiab txij nkawm
Kev tsim kho kom zoo thiab kev txij nkawm yog qhov tseem ceeb los ua kom muaj kev lag luam zoo ntawm SPD.
· Ecy Epectorialistial kev sib txuas: txhua SPD sab hauv cov lus qhia yuav tsum muaj kev sib txuas rau hauv lub tsev tsim kev tiv thaiv lub tsev.
· Txawv cov lus qhia: cov xov hlau (theem cov hlau, hauv av hlau) Txuas SPD yuav tsum muaj hla hla} {ntu ntu. Feem ntau, nws raug nquahu tias cov hlau loj loj dua los yog sib npaug rau 10mm ² thiab hauv av xaim loj dua lossis sib npaug nrog 16 hli ².
· Soj Ntsuam Xyuas: Xaiv SPDs nrog cov xwm txheej qhov rai (ntsuab / liab) lossis chaw taws teeb pom kev sib txuam rau kev tshuaj xyuas txhua hnub thiab hloov sijhawm ntawm cov qauv ua txhaum cai. Nws raug nquahu kom ua kev kuaj mob ua ntej lub caij thundmentorm txhua xyoo.
Ntsiab lus thiab ceeb toom
Feem ntau, thaum xaiv cov kws tiv thaiv cov tub sab, thov nco qab cov theem hauv qab no:
1. Qhia meej qhov chaw thiab qib: Ua ntej, txiav txim siab qhov twg SPD, faib ua ntej lub thawv, lossis rov txiav txim siab ua ntej yuav xaiv hom 1, ntaus 2, lossis ntaus 3.
2. Khij cov ntsuas rau kev sib piv: tsom rau UC, nce, thiab tam sim no nqa lub peev xwm los xyuas kom lawv phim cov khoom siv hluav taws xob thiab theem voltage.
3. Cov txheej txheem kev yoog raws kev nyab xeeb: Xaiv hom kev tiv thaiv yog thiab tus lej raws li lub zog hluav taws xob, thiab nco ntsoov teeb tsa cov khoom siv thaub qab uas tsim nyog rau nws.
4. Qauv teeb tsa yog lub hauv paus: nruj me ntsis ua raws cov kev qhia tshwj xeeb rau kev tsim kho, tshwj xeeb tshaj yog cov hlau xaim yuav tsum yog luv thiab tuab.
