Mea Hoʻomalu Palekana Piʻi (SPD): Palekana Koʻikoʻi no nā ʻōnaehana uila hou

I kēia ao e hoʻonui nui ʻia ana ka uila a me ka pilina, ua pilikia mau nā ʻōnaehana uila i nā pilikia e like menā hahau uila, nā piʻi hoʻololi, a me nā overvoltage transientHiki i kēia mau piʻi koke ʻana o ka uila ke hōʻino nui i nā lako uila, hoʻopilikia i nā hana, a alakaʻi i ka manawa hoʻomaha pipiʻi. ʻO kēia kahi eNā Mea Hoʻomalu Palekana Piʻi (SPD)e pāʻani i kahi kuleana koʻikoʻi.

He aha ka SPD?

A Mea Hoʻomalu Palekana Piʻi (SPD)ua hoʻolālā ʻia epale i nā ʻōnaehana uila a me nā lako mai nā overvoltage transientma ka hoʻohuli ʻana i ka ikehu piʻi keu me ka palekana i ka honua. Ke hana ʻia kahi piʻi, pane koke ka SPD, e kaupalena ana i ke voltage i kahi pae palekana a pale i ka hōʻino ʻana i nā mea pili.

No ke aha he mea nui nā SPD?

He mea nui nā SPD no ka hōʻoia ʻana:

• Palekana LakoKa palekana ʻana i nā mea uila a me nā mea uila koʻikoʻi mai nā piʻi uila
• Ka Hilinaʻi o ka ʻōnaehana: Hoʻemi i ka downtime i hoʻokumu ʻia e nā hemahema e pili ana i ka piʻi ʻana
• Hōʻoia Palekana: Ke pale ʻana i nā pōʻino e like me ka haki ʻana o ka insulation a i ʻole nā ​​pilikia ahi
• Ka Pono o ke Kumukūʻai: Hoʻemi i nā kumukūʻai hoʻoponopono a me ke pani

Me nā manawa pane i ana ʻia manā nanokekona, Hana nā SPD ma ke ʻano he laina pale wikiwiki a hilinaʻi hoʻi no nā ʻōnaehana uila.

Nā hiʻohiʻona noi maʻamau

Hoʻohana nui ʻia nā SPD ma nā ʻoihana like ʻole a me nā wahi, e like me:

• Nā hale hana ʻoihana a me nā hale hana hana
• Nā hale kalepa a me nā keʻena
• Nā ʻōnaehana uila noho
• Nā kikowaena ʻikepili a me nā ʻōnaehana kamaʻilio
• Nā ʻōnaehana ikehu hou e like me nā hoʻonohonoho solar (PV)
• Nā pūnaewele hoʻokaʻawale mana

ʻO nā mea ʻeluaNā ʻōnaehana AC a me DCpono ka palekana o ke piʻi ʻana, ʻoiai ma nā wahi i hōʻike ʻia i ka uila a i ʻole nā ​​​​hana hoʻololi pinepine.

Nā Hoʻonā SPD Uila Mutai

Ma ke ʻano he mea hana ʻoihana o nā lako uila haʻahaʻa,Pūʻulu Uila ʻo Mutaihāʻawi i kahi laulā piha oNā Mea Hoʻomalu Palekana AC a me DC, i hoʻolālā ʻia e hāʻawi i ka palekana hilinaʻi a me ka pono no nā noi like ʻole.

Moʻo AC SPD

ʻO MutaiAC SPDkūpono nā huahana noNā ʻōnaehana 220V/380V, e hāʻawi ana i ka palekana ikaika e kūʻē i nā au piʻi i hoʻokumu ʻia e ka uila a i ʻole nā ​​​​​​pilikia o ka pūnaewele.

ʻO nā hiʻohiʻona koʻikoʻi:

• Ka nui o ke au hoʻokuʻu (Imax)a hiki i100kA (8/20μs)
• Ka manawa hoʻokuʻu inoa (In)a hiki i60kA (8/20μs)
• Pae palekana haʻahaʻa (I luna)mai1.5kV a i 2.5kV
• Ka manawa pane wikiwikio ka emi ma mua o20ns
• Ke au leaka haʻahaʻano ka hoʻonui ʻana i ke kūpaʻa o ka ʻōnaehana

He kūpono kēia mau SPD no ka pale ʻananā panela hoʻolaha, nā keʻena uila, a me nā ʻōnaehana mana hale.

Moʻo SPD DC

ʻO MutaiDC SPDua hoʻolālā kūikawā ʻia nā huahana noNā ʻōnaehana DC, ʻoi aku hoʻi manā noi photovoltaic solar (PV)a me nā ʻōnaehana ikehu hou ʻē aʻe.

ʻO nā hiʻohiʻona koʻikoʻi:

• Ka nui o ka uila hana mau (Uc)a hiki iDC1500V
• Ka manawa hoʻokuʻu inoa (In) of 20kA (8/20μs)
• Ka nui o ke au hoʻokuʻu (Imax) of 40kA (8/20μs)
• Pae palekana (I luna)≤3.2kV
• Ka manawa pane wikiwiki loa of 25ns
• Kūlike meKe kau ʻana o ka DIN railno ka hoʻohui maʻalahi

Mālama pono kēia mau mea hanaNā ʻōnaehana PV, nā ʻōnaehana hoʻolaha DC, a me nā kikowaena mālama ikehumai nā piʻi pōkole.

Ka Palekana Hilinaʻi Hiki iā ʻOe ke Hilinaʻi

Me ka hoʻolālā holomua, nā ʻāpana kiʻekiʻe, a me nā kūlana hana paʻa, hāʻawi nā huahana SPD a Mutai Electrichana paʻa, pane wikiwiki, a me ka hilinaʻi lōʻihiInā paha ma nā wahi ʻoihana a i ʻole nā ​​​​ʻōnaehana ikehu hou, kōkua kā mākou SPD i ka hōʻoiaka hana mau a me ka palekana o nā lako.
