He aha nā Surge Arresters a me SPDs i nā ʻōnaehana uila a me nā ʻōnaehana solar

ʻIke pinepine wau i ka huikau ma waena o nā SPD a me nā mea hopu surge, a hoʻonāukiuki ia i nā hui kūʻai e makemake wale ana i ka palekana hilinaʻi.

Mālama nā mea pale uila a me nā SPD i nā ʻōnaehana uila mai nā overvoltage transient ikehu kiʻekiʻe. Hoʻopaʻa a hoʻohuli nā SPD i nā surges, ʻoiai ke ālai nei nā mea pale uila i nā impulses uila ma nā pae ikehu kiʻekiʻe. Hoʻemi nā mea ʻelua i ka hāʻule ʻana o nā lako a hoʻomaikaʻi i ka hilinaʻi o ka ʻōnaehana.

ʻOkoʻa ka hana ʻana o nā Surge Arresters a me nā SPD ʻoiai ke kuhikuhi nei lākou i ka pilikia like. Hoʻohana nui ka SPD i nā ʻāpana MOV a i ʻole GDT e kaupalena i nā spike voltage transient. Hoʻonoho pinepine ʻia kahi Surge Arresters ma ka puka lawelawe e ālai i nā impulses uila ikehu kiʻekiʻe mai ke komo ʻana i ka hale. Hoʻohana au i nā SPD ma nā kaapuni downstream no ka mea hana wikiwiki lākou, ʻoiai ke hoʻohana nei au i nā Surge Arresters ma ka panela nui no nā hanana uila kaumaha.

Ka wehewehe ʻana o SPD vs Surge Arrester

Hoʻopaʻa ka SPD i ka overvoltage ma ke kāohi ʻana i ka piʻi ʻana, ʻoiai ʻo ka mea hopu piʻi e hoʻohuli i ka uila ikehu kiʻekiʻe i ka honua me ka ʻole e ʻae iā ia e komo i loko o ka hale. Hoʻākāka mau wau i kēia ʻokoʻa e pale aku i ke koho huahana hewa.

Pehea e hana ai ka ʻenehana MOV i nā hāmeʻa Surge

Hoʻololi nā MOV i ke kū'ē ma muli o ke ana uila. Ke piʻi aʻe nā piʻi, hāʻule koke ke kū'ē MOV, e hoʻouna ana i ka ikehu keu i ka honua. He wikiwiki kēia hopena, paʻa, a kūpono hoʻi no nā noi SPD ʻoihana.

Nā ʻĀpana Koʻikoʻi: MOV, GDT, Fuse Thermal

• MOV lawelawe i nā piʻi wikiwiki

• ADG lawelawe i nā au uila nui

• Fuse wela hoʻokaʻawale i ka wā e wela nui ai ʻo MOV

Hana pū kēia mau ʻāpana ʻekolu e hāʻawi i ka palekana paʻa.

Ka Palekana PV Surge no nā Panel Solar a me nā Inverters

He ʻike nui nā mea kanu lā i ka uila a me nā piʻi hoʻololi, no laila ke paipai mau nei au i ke kau ʻana i nā SPD ma nā ʻaoʻao AC a me DC.

Mālama nā PV SPD i nā kaula o ka lā, nā inverters, nā mea hoʻokele MPPT, a me nā mea nānā. Hoʻemi lākou i ka manawa downtime a hoʻolōʻihi i ke ola o ka ʻōnaehana.

Nā Wahi Palekana PV

Palekana Piʻi no nā ʻōnaehana mana solar

Ua hoʻolālā ʻia kēia mau SPD e lawelawe i ka uila DC mau a me nā piʻi uila i maʻamau i nā hoʻonohonoho kahua ākea.

Ke kuleana o SPD ma nā pahu DC Combiner a me PV Array

ʻO nā pahu hui pū ka wahi komo mua o nā piʻi. Pono e hoʻokomo ʻia nā SPD ma aneʻi e hoʻōki i ka hapa nui o ka ikehu ma mua o ka hiki ʻana i ka inverter.

Pehea e pale ai i nā uila a me nā mea hoʻokele o ka lā

Hoʻomalu wau i nā mea hoʻokele ma ka hoʻohui ʻana i nā Type 2 AC SPDs ma ka hoʻopuka a me nā Type 2 DC SPDs ma ka hoʻokomo. Hoʻokumu kēia i kahi kaulahao palekana i hoʻonohonoho ʻia.

Nā Koina Hoʻokomo no nā SPD AC/DC ma nā ʻōnaehana Solar

ʻO ka hoʻokomo maikaʻi ʻole ke kumu nui o ka hāʻule ʻana o SPD, a ʻike pinepine wau i kēia ma nā hale hana a me nā mahiʻai solar.

ʻO ke koho ʻana i nā uea pololei, ka hoʻokumu ʻana i ka honua, a me ka SPD e pale aku i ka wela nui ʻana, ka hoʻopunipuni wahaheʻe, a me ka hōʻino ʻana o ka insulation. Pono nā mea hoʻonoho e hahai i nā ala uea pōkole a me ka hoʻopaʻa pono ʻana.

ʻO ke kaula kūpono no ka AC SPD Single-Phase a me 3-Phase

Mālama au i ka lōʻihi o nā uea ma lalo o 0.5m e hoʻomaikaʻi i ka manawa pane SPD. Hoʻemi nā uea lōʻihi i ka ikaika pale.

Pehea e hoʻouka ai i ka SPD ma nā kaapuni PV DC 1000V

Pono e hoʻokomo ʻia nā PV DC SPD me ka polarity pololei a me ka hoʻokumu ʻana. Ke hahai pono nei au i nā kiʻikuhi a ka mea hana e pale aku i nā pōpilikia o ke au hoʻohuli.

Nā Koina Hoʻokumu Honua a me nā Hoʻopaʻa no nā Mea Hana Surge

Pono ke kāpili ʻana i ka impedance haʻahaʻa a hoʻopili ʻia i ka busbar honua nui. ʻO ka hoʻokumu ʻana i ka lepo maikaʻi ʻole ke kumu o ka hana hewa ʻana o ka SPD.

Ke koho ʻana i ka pahu uhi pale surge kūpono

Pono nā hoʻonohonoho waho i ka IP65 a i ʻole nā ​​​​pahu kiʻekiʻe e pale aku i ka hōʻino ʻia ʻana o ka makū.

Hana a me ke ʻano palekana o ka MOV Surge Arrester

ʻO nā MOV ke kumu o ka hapa nui o nā SPD aʻu e hoʻohana nei, ʻoi aku hoʻi ma nā ʻano ʻoihana.

Hoʻopaʻa nā mea pale loʻi MOV i nā loʻi ma ka hoʻohaʻahaʻa koke ʻana i ke kū'ē ke piʻi aʻe ka voltage ma mua o ka paepae. Hāʻawi lākou i ka palekana wikiwiki a paʻa no nā hale hana a me nā ʻōnaehana solar.

He aha ka mea hoʻopaʻa MOV Surge

Hoʻohana ia i ka mea semiconductor metal-oxide e ʻike i nā piʻi a hoʻohuli iā lākou i ka honua.

Nā ʻano hāʻule MOV a me ka hoʻokaʻawale wela

Hiki i nā MOV ke wela loa ma hope o nā piʻi pinepine ʻana, no laila e hoʻokaʻawale palekana nā fuse thermal. Koho wale wau i nā SPD me nā hiʻohiʻona hoʻokaʻawale thermal.

Pehea e pale ai nā polokalamu MOV mai nā impulses uila

Hoʻopili lākou i ke alo o ka uila a pale iā ia mai ke komo ʻana i nā mea uila ma lalo.

Alakaʻi Kūʻai: Pehea e koho ai i ka SPD kūpono no kāu noi

Ke kōkua aku nei au i nā hui kūʻai, ke nānā mau nei au i ka uila, ka helu o ke au, a me ka palapala hōʻoia.

E koho i nā SPD e pili ana i ke ana uila o ka ʻōnaehana, ka helu Imax, ka manawa pane, a me nā palapala hōʻoia e like me UL1449/IEC61643. No nā ʻōnaehana AC/DC i hui pū ʻia, e koho i nā SPD kaʻawale no kēlā me kēia ʻaoʻao.

Ke ana ʻana i nā SPD no nā ʻōnaehana 100A, 220V, a me 480V

Pono nā ʻōnaehana voltage kiʻekiʻe i nā helu MCOV a me Imax kiʻekiʻe. Pono nā laina ʻoihana 480V i nā SPD Type 1/2 ikaika.

Ke koho ʻana i ka AC vs DC SPD no nā ʻōnaehana solar i hui pū ʻia

Mai hoʻololi iā lākou. Hoʻokele nā ​​​​DC SPD i ka polarity mau; Kūkulu ʻia nā AC SPD no nā ʻano nalu like ʻole.

Pehea e koho ai i nā lama SPD a me nā palapala hōʻoia

Koho au i nā mea hoʻolako me ka QC paʻa, nā palapala maopopo, a me ka hoʻouna ʻana i hiki ke wānana ʻia—ʻoi aku hoʻi no nā mea kūʻai aku hana nui e like me kāu.
