36 Sidall Structure Voltage switching mtundu ac mphezi surge chitetezo (8/20μs)
Pamene mvula yamkuntho ikubwera, chitetezo cha mphezi ndichofunika kwambiri panthawiyi. Mphezi zimalowa m'chipindamo kudzera mu zingwe zamagetsi kapena njira zina, kuwononga anthu ndi zipangizo; LEIHAO Lightning Protection Company ili ndi zinthu zambiri zoteteza mphezi, zomwe chitetezo chamagetsi ndi gawo lofunikira. Tsopano tifotokoza mwachidule magawo ndi kugwiritsa ntchito kwa chitetezo chapamwamba kwambiri.
(1) kutsogolo kumapeto kwa chosinthira chachikulu chamagetsi mubokosi yogawa pansi, LH-50I 4P imagwiritsidwa ntchito ngati chitetezo choyambirira chamagetsi;
② LH-50I 4P iyeneranso kugwiritsidwa ntchito kumapeto kwa voliyumu yotsika ya thiransifoma komanso kumapeto kwa switch yayikulu yamagetsi.
③ Pamene bokosi logawa limakhala lodziimira panja, LH-50I 4P iyeneranso kugwiritsidwa ntchito ngati chitetezo chachikulu chamagetsi. Zida zolumikizidwa ndi netiweki yamagetsi ya AC zimakhudzidwa mosavuta ndi mavuto ambiri amagetsi omwe angayembekezere kugwira ntchito kosakhazikika, zomwe zimabweretsa kulephera kwa zida. , kuchepetsa moyo ngakhale kuwonongeka. Oteteza maopaleshoni a LH-15I adapangidwa kuti akwaniritse zofunikira zachitetezo pazida zonse zotsika mphamvu zopangira mphezi zamakampani. Zogulitsa za mndandandawu zimagawidwa ndi mtundu wazinthu ndi gulu lamagetsi (AC kapena DC).

1. Muyezo wa kapangidwe kazinthu: Izi zidapangidwa molingana ndi miyezo yapadziko lonse lapansi ya IEC, ndipo magwiridwe ake amakwaniritsa zofunikira za National Standard GB 18802.1-2011 "Low Voltage Surge Protector (SPD) Gawo 1: Zofunikira pakuchita ndi njira zoyesera zachitetezo cha opareshoni pamagetsi otsika magetsi ".
2. Kuchuluka kwazomwe zimagwiritsidwa ntchito: GB50343-2012 Khodi Yaumisiri Yachitetezo cha Mphezi Yomanga Zamagetsi Zamagetsi
3 Kusankhidwa kwa chitetezo cha opaleshoni: SPD yoyamba iyenera kukhazikitsidwa mubokosi lalikulu logawa pakhomo la magetsi omangamanga.
4. Zogulitsa: Izi zili ndi mawonekedwe amagetsi otsika otsalira, liwiro loyankhira mwachangu, mphamvu yayikulu yamakono (Imppulse current Iimp (10/350μs) ndi 25kA/ mzere, moyo wautali wautumiki, kukonza kosavuta komanso kukhazikitsa kosavuta, ndi zina zambiri.

● Mphamvu ziyenera kudulidwa musanayike, ndipo ntchito yamoyo ndiyoletsedwa
● Ndikofunikira kulumikiza fuse kapena chowotcha chodziwikiratu pamndandanda kutsogolo kwa gawo loteteza mphezi
●Mukayika, chonde gwirizanitsani molingana ndi chithunzi cha unsembe. Mwa iwo, L1, L2, L3 ndi mawaya agawo, N ndi waya wosalowerera, ndipo PE ndi waya wapansi. Osachilumikiza molakwika. Mukatha kukhazikitsa, tsekani chosinthira chamagetsi (fuse) chosinthira
● Pambuyo pa kukhazikitsa, fufuzani ngati gawo loteteza mphezi likugwira ntchito bwino
10350gs, mtundu wa chubu chotulutsa, ndi zenera: pakugwiritsa ntchito, zenera lowonetsera zolakwika liyenera kuyang'aniridwa ndikuwunika pafupipafupi. Pamene zenera lowonetsera zolakwika liri lofiira (kapena chizindikiro chakutali cha mankhwala ndi chizindikiro cha alamu chakutali), zikutanthauza gawo loteteza mphezi Pakalephera, liyenera kukonzedwa kapena kusinthidwa panthawi yake.
● Ma modules otetezera magetsi oyendera magetsi ayenera kuikidwa mofanana (Kevin wiring angagwiritsidwenso ntchito), kapena mawiri awiri angagwiritsidwe ntchito kuti agwirizane. Nthawi zambiri, mumangofunika kulumikiza chimodzi mwazitsulo ziwirizi. Waya wolumikizira uyenera kukhala wolimba, wodalirika, wamfupi, wandiweyani, komanso wowongoka.
