Chipangizo choteteza mpweya cha 1500V 3P T2 chothandizira mpweya woziziritsa | LKX-PV

The Chipangizo Choteteza cha Mtundu 2 cha SPD Surge 20–40kA 1500V DC 3-Pole (LKX-PV) yapangidwa kuti igwiritsidwe ntchito makina amphamvu a DC okhala ndi mphamvu zambiri komanso amphamvu kwambiri, kupereka chitetezo chodalirika cha Gulu Lachiwiri ku mphamvu yamagetsi yosakhalitsa, kusinthasintha kwa mafunde, ndi mafunde amphezi oyambitsa. Ma module a MOV amphamvu kwambiri, chitetezo cha kutentha, ndi ma circuitry oyankha mwachangu, zimathandiza kuti ntchito ikhale yokhazikika kwa nthawi yayitali ma PV arrays akuluakulu, mabokosi ophatikiza, ma inverter apakati/a zingwe, makabati ogawa magetsi a DC, makina osungira mabatire, ndi zomera za dzuwa za 1500V DC.

Lumikizanani nafe Tsitsani

tsatanetsatane wa malonda

Tanthauzo la Chitsanzo

Mfundo ya malonda ndi momwe ntchito ikuyendera

1. Amakumana ndi mayeso a SPD a ClassⅡ (8/20μs)

2. Kutengera ukadaulo wa zinc oxide

3. Pogwiritsa ntchito 34S MOV, mphamvu yokwanira idzakhala mpaka 8/20μs 40kA

4. Palibe mphamvu yoyendera mosalekeza

5. Kutentha kwa malo ogwirira ntchito ndi -40°C~+80°C

6. Ntchito yolumikizirana patali ndi yosankha.

7. Zinthu zikagwa, zenera lobiriwira limayamba kufiira ndipo chizindikiro chakutali chimapereka ntchito yochenjeza kutali

Mawonekedwe akunja ndi miyeso yoyika

Zoganizira za kukhazikitsa

1. Musanayike, onetsetsani kuti magetsi atsekedwa. Kugwiritsa ntchito magetsi mukadali ndi mphamvu n'koletsedwa.

2. Ndikofunikira kukhazikitsa fuse kapena circuit breaker motsatizana kumapeto kwa gawo loteteza ma surge.

3. Tsatirani chithunzi choyikira kuti mulumikizane panthawi yoyikira. DC+ ndiye positive pole, DC- ndiye negative pole, ndipo PE ndiye ground wire. Pewani kulumikizana kolakwika. Mukayiyika, tsekani circuit breaker (kapena fuse) switch ndikuwona ngati ntchitoyo ili bwino.

4. Mukamaliza kuyika, ikani gawolo pamalo pake ndikutsimikizira ngati gawo loteteza ma surge likugwira ntchito bwino.

5. Mukagwiritsa ntchito, yang'anani nthawi zonse gawo loteteza kugwedezeka ndikuwona momwe zenera lowonetsera zolakwika lilili. Ngati zenera lowonetsa zolakwika likhala lofiira kapena ngati malo olumikizirana akutali atulutsa chizindikiro cha alamu, zimasonyeza kuti gawo loteteza kugwedezeka silikugwira ntchito bwino, lomwe liyenera kukonzedwa kapena kusinthidwa mwachangu.

6. Ma module oteteza mphamvu zamagetsi olumikizidwa mofanana ayenera kuyikidwa motsatizana. Mawaya olumikizira ayenera kukhala otetezeka, odalirika, afupiafupi, okhuthala, komanso owongoka.
