Izixhobo zoKhuseleko ze-OBO vs Leikexing Surge: Uthelekiso lwezeMveliso luka-2025

Ndisakhumbula mhla i-40 kA surge yatsha kwenye yeekhabhathi zethu zolawulo kunyaka ophelileyo. Oko kusilela kwasishukumisela ukuba senze uvavanyo olupheleleyo, oluhambelanayo lwe-OBO kunye ne-Leikexing SPDs phantsi kweemeko zolawulo zoxinzelelo.

Ngowama-2025, i-OBO isaqhubeka nokuba ngumgangatho weendawo zoshishino ezisebenza nzima, ngelixa iLeikexing inika malunga ne-90% yokhuseleko malunga ne-60% yeendleko. Ndilawula indawo engama-2,000 m² eWenzhou kwaye ndibonelela ngazo zombini ezi mpawu, ngoko ke idatha engezantsi ivela kwiifayile zokwenyani—hayi kwiincwadana zokuthengisa.

Ukuba ungumthengi wobunjineli ofuna ukusebenza ngokuchanekileyo, i-TCO, ii-surge curves, kunye nedatha yokuthembeka kwexesha elide ngaphambi kokuba usayine i-PO, eli nqaku likunika kanye loo nto.

 Ngoba Ii-SPD ze-OBO Isikhundla Esiphezulu kwi Iinkqubo zamandla emizi-mveliso

Kwiminyaka embalwa eyadlulayo, umbane we-50 kA wabetha omnye wabathengi bethu beemoto baseYurophu. Iiyunithi zabo ze-OBO zayithintela i-surge kwaye umgca wemveliso awuzange ume. Eso siganeko sabonisa ukuba kutheni i-OBO iqhubeka nokuba lolona khetho lukhethwayo kwizicelo zoshishino ezinobuzaza.

Ndifake iiyunithi ezingaphezu kwama-3,000 ze-OBO Type 1 kunye ne-Type 2 ukusukela ngo-2018. Zihlala ziphumelela uvavanyo lwe-25 kA 10/350 µs nge-

 Ngaphakathi kwi-OBO Design

Ikheyiji ye-varistor ehlanganisiweyo ye-OBO iqinisekisa ukwabelana ngombane kwaye ithintela nayiphi na idiski ukuba ingadluli kwi-70% yomthwalo. I-fuse yobushushu yoomatshini iyaqhawuka ngokucocekileyo malunga ne-140 °C. Emva kokuhlola iiyunithi ezingama-50 ezibuyisiweyo, ezintathu kuphela ezibonise naluphi na utshintsho oluncinci lombala—ubungqina bozinzo lobushushu oluqinileyo lwexesha elide.

 Indlela Esiqinisekisa Ngayo I-OBO KwiLebhu Yethu

Ibhetshi nganye engenayo ivavanywa nge-15 kA 8/20 µs impulse kusetyenziswa ijenereyitha yethu ye-200 kA Marx. Sijonga ukutyibilika kwe-clamp voltage kunye nokuvuza. Iiyunithi zokugqibela ezingama-200 zibonise oku kulandelayo:

1. Umahluko weClamp: ≤ 0.3%

2. Ukuvuza:

Loo nqanaba lokungaguquguquki lihambelana ngokusondeleyo nee-curves ezipapashwe yi-OBO.

 Iindleko Zokwenyani Zobunini (i-TCO Yeminyaka Eli-10)

Nantsi indlela elula yokwahlulahlula iindleko zeminyaka eli-10 esiyisebenzisela abathengi:

I-OBO iyaphumelela xa kusetyenziswa izaphulelo zeinshorensi. Ngaphandle kwezaphulelo, iLeikexing iba nomtsalane ngakumbi.

 Iimpawu eziphambili ze-OBO Uhlobo 1 kunye nohlobo lwe-2 SPDs

I-12 kV line-to-ground spike yabetha i-main breaker yethu ngoJulayi ophelileyo. I-OBO Type 1 SPD yayifumana ngoko nangoko, kwaye i-PLC yethu ayizange ivumele ukuvumelanisa.

Izibambo ze-OBO Type 1 25 kA 10/350 µs, ngelixa uhlobo lwesibini luxhasa 100kA 8/20µsZombini zabelana ngobubanzi bemodyuli efanayo kwaye ziquka umqondiso okude—ziluncedo ekudibaneni neenkqubo zokubeka esweni ze-PLC.

Ukuqhekeza iBhloko yohlobo loku-1

Idiski ye-varistor engama-40 mm ityebile ngama-34% kunaleyo ikwiyunithi ye-T2. Ubunzima bobushushu obuninzi buthetha oku kulandelayo:

1. Ukunyuka kobushushu obuphantsi (umahluko we-≈ 8 °C)

2. Ukwaluphala kancinci phantsi kokunyuka okuphindaphindiweyo

3. Uzinzo olungcono kwiindawo ezine-switching transients

 Amanqaku abalulekileyo kwiiyunithi zohlobo lwesibini

I-OBO Type 2 SPD inikwe i-100 kA, kodwa iqinisekisiwe kuphela Ukunyuka okungama-20kuloo nqanaba. Izibonelelo ezine-micro-surge frequency ephezulu (umz., amaziko edatha) kufuneka zisebenzise:

1. Iiyunithi ezimbini ze-T2 ngaxeshanye

2.Ukujikeleza konyaka ukuze kunxibeke ngokulinganayo

Khawuleza IsalathisoItafile

 Ii-SPD zeLeikexing zezicelo ze-AC kunye ne-PV

Ndaseka iLeikexing ngo-2015 kuba iimpawu eziphambili zeSPD zala ukubonelela ngee-odolo ezincinci zePV. Namhlanje sithumela iiyunithi ezingaphezu kwama-80,000 ngonyaka kwihlabathi liphela.

Izibambo zethu zomgca we-AC 20 kA 10/350 µskunye nezigqubuthelo zethu zomgca we-PV 40 kA 8/20 µskunye neendlela zombane kwi-275 V, 600 V, kunye ne-1,000 V. Ibhetshi nganye yemveliso idlula kwiiyure ezingama-48 zokuguga kwi-85 °C kwaye ihambelana ne-IEC 61643-11 kunye ne-ISO 9001.

 Ngaphakathi kweResiphi yethu yeVaristor

Sifumana iidiski ze-MOV ezingama-32 mm ezivela kubavelisi abaphezulu ababelana ngazo neemveliso eziphambili ze-EU. Ukuprinta kwethu ipeyinti yesilivere enamaleko amathathu kunciphisa i-voltage yokudubula malunga ne- 12Vkwaye iqinisa ukunyamezelana kwe-clamp. Kwiidiski ezili-1,000 esizilinganisileyo:

1. Ukusasazwa kweVoltage: ±4V

2. Isiqingatha sotshintsho olubonwe kwinkqubo yethu ka-2020

 Iinkcukacha ze-PV String SPD

Ii-PV arrays zihambahamba malunga ne-±800 V, kwaye iimpazamo zomhlaba zinokunyusa nayiphi na ipali ukuya kwi-1,100 V. I-capacitor yethu ye-Y2 edibeneyo izinzisa zombini iipali kwaye igcina i-voltage ye-varistor ingaphantsi kwe-900 V. Kuvavanyo lophahla lwe-150 kW olune-6 kV impulses:

1. I-Inverter iqala kwakhona: 0

2. Uphawu lwangaphambili kwindawo enye: Ukuqalisa kwakhona okungama-23 ngexesha lesiphango ngasinye

Intoni IzakwiBhokisi

1. Isiseko sesitimela se-DIN

2. Imodyuli yeplagi enesalathisi sombala

Iikliphu zekheyiji ze-L/N eziyi-3.6 mm²

I-clamp yekheyiji ye-PE eyi-4.16 mm²

Ikhowudi ye-5.QR edityaniswe nengxelo yovavanyo lwebhetshi

6. Ivawutsha yokutshintsha iminyaka emihlanu

Ukuba ivawutsha ibonakala ebhokisini kunceda ukunciphisa iinkxalabo zabathengi kwaye kunciphisa ukungqubana kwebango.

Uthelekiso lobuchwephesha: OBO vs Leikexing SPD

Sifake zombini ii-SPD kwi-DIN rail efanayo saza sazifaka kwii-surge pulses ezifanayo. Phantsi kovavanyo lwe-20 kA 10/350 µs:

1.Isibambo se-OBO:0.9 kV

2.I-Leikexing clamp:1.05 kV

Zombini zidlulile kwiimfuneko zokunyamezela ubushushu kunye nokunyuka kwesantya. I-OBO ibonelela ngemiqondiso ekude, ngelixa iLeikexing ibonelela ngendlela yokuseta kwakhona kunye nexabiso eliphantsi.

 Iziphumo zoVavanyo lokunyuka kwesisu ecaleni

Apha ngezantsi kukho idatha yovavanyo oluvela kuvavanyo lwethu lotyando olulawulwayo:

Umahluko (≈150 V) ubaluleke kakhulu kwimithwalo enobuthathaka kakhulu efana ne-elektroniki eqhutywa yi-SMPS.

 Uvavanyo lwe-Thermal Runaway

Kwi-oven engama-70°C kwi-1.3 Uc iiyure ezine:

1. I-fuse yobushushu ye-OBO ivulwe kwi ≈142 °C

2. I-Leikexing breaker ivulwe apha ≈138 °C

Isixhobo sokuqhekeza i-Leikexing sinokusetwa kwakhona, nto leyo enceda kwiindawo zonxibelelwano ezikude okanye kwiindawo zangaphandle.

 Isiseko kunye nokuhambelana

1. Zombini zi Iiyunithi zemodyuli ezi-4

2. Imingxunya yokufaka ihambelana ngaphakathi kwe-0.5 mm

3. Ukutshintshwa ngokuthe ngqo kokungena kunokwenzeka

Sivavanye utshintsho oluphilayo kwindawo ethile eIndiya; utshintsho luthathe imizuzu esixhenxe kuphela.
