He aha mea he maloo-type transformers? Hoakaka a me ka laulā

I ka hoʻohana 'ana i ka mana pae pono e hoʻololi i kekahi anakahi uila. Maloo-ʻano transformers - hanaʻia i kēia kuleana pili i ka malu a me ka pono no laila, i ka mea e hoʻomano hoʻohana 'ia no i loko o mea hoʻonoho i ka lehulehu a me ka noho hale, kahi i nāʻano o kēia mau mea i manaoia e eʻoi aku risky (ai ole o ka lewa-ho'ēmi).

Mea hoʻololi uilaʻAno: wai a me ka maloo

I ka rula, loaʻa nō nāʻano o ia mea: he kinowai'īpale a me ka huʻihuʻiʻana (wai a type) a ho'ēmi me ka lewa a me ka lewa-kinoea läÿau, (maloo type).

No ka mea muaʻano mea hoʻololi uila anuanu meakino i ia iʻike mau mea pōhaku aila. I pili nā waiwai, e like me inflammable hydrocarbons a me ka mea pīlali fluids. Kēia mau transformers i kekahi kāna mau 'ōlelo a me nāʻanuʻu i bapetizoia i loko o ka pahu i loaʻa i ke kinowai meakino, a lawelawe' ana me ka insulator, a me ka cooler.

Most, he pono ole ka mana transformers i maloʻoʻanuʻu Uploaded pīlali kēpau ana me ka insulator. Ka mea, i malama ka conductors mai ka lepo a me ka lewa ka popopo. Eia naʻe, mai ka punahelu no ka hoolei ana i pōkaʻa mea hoʻohana wale me ka paʻa nui like 'ole, ka mea i hiki ke hoʻololi i ka manao o ia mau manaʻo mea emi. Ma ka laulā mau hoʻohana i ka uila mana lako o ka poe liilii, hanalima hana, e like me ka pono me ka lehulehu a me ka noho hale, maloo-type transformersʻokoʻa ma ka nānā me ka helu o nā pihana'ū o kona wai counterparts.

Ka papa kuhikuhiE kiko'î

Ka loaʻano nui loa i loko o ka hana o ka noonoo maalea - mea e hoʻopaʻa i ke ana wela o nāʻanuʻu. E kōkua i ke koho 'ole kūʻai i ka mea no ka maloo-ʻano mana lako hou i ka likeʻole mea, noonoo i kekahi mau kumu o pae'ōnaehana kiko'î:

1. KVA.
2. Na Loipālākiō anakahi uila o ka iniiaiie a me nā haumānaʻanuʻu.
3. Heat hoolilo'īpale'ōnaehana - i ka nui o ka mea i kā mākou Ambient mahana o +ʻawelike ala i loko o nāʻanuʻu + likeʻole ma waena o kaʻawelike ala hou i loko o nāʻanuʻu, a me ka kiekie loa huahelu i loko o ia mau mea.
4. Na kāna mau 'ōlelo a me ka'ōwili hao - o ka mau mea nui e hiki poino i ka kāna mau' ōlelo a me ka hoʻomāhuahua o nā pua (keleawe a Aluminum conductors).

Aia i acee? Iuo oeiia o ka mea hoʻololi uila manao i ho'ākāka 'kuhikuhi i hoʻohana ki ina hana like o ka hoʻokaʻawale oʻanuʻu. Iwaena o lakou e maopopo loa: holo impregnation, encapsulation a me ka hoolei'ōwili hao. E hoi kakou i kela mea keia mea o lakou a kaawale.

Hoʻokaʻawale holo impregnation kaʻina (VPI)

Kēia 'ike loea i ka mea lacquer ka penaʻana conductors ma alternating puʻe a me ka holo pōʻaiapuni. VPI-kaʻina hoʻohana polyester kēpau. Ua hoʻolako oi varnished conductors ma mua oʻike mau kaiapuni haku mele 'ana. Coils, uhi ia, alaila, waiho iho la i loko o ka umu ahi, ma ke kāluaʻia. Ka mea, e nui aku hoʻopale ai i ka hanana o corona hookuuia. Pehea e holo ai e like me ka mea hoʻololi uila? Photo ia mea ma lalo.

Hoʻokaʻawale ma ka holo encapsulation (VPE)

Kēia papa hana mea nui i oi i VPI-kaʻina. Mau kaiapuni i hoʻohuiʻia i loko o ka manufacturing kaʻina e encapsulate i ka'ōwili hao, ma hope i ka mea i kālua i loko o ka umu ahi ka penaʻana. Mau transformers nō ka mea maikaʻi loa ka palekana i kaʻano pākīkē, a humid hana kūpono ma mua o lākou VPI-analogues. Pehea e holo ai e like me ka mea hoʻololi uila? Photos hooku iho la ia ma lalo ia.

Encapsulation (hoailona iho la i)

Encapsulated transformers - heʻike mau mea me coils uhi me ka silikone i huiʻia ai pīlali kēpau, a puni iho la ia ma ka pōkā pū kaumaha loa. ? Iecaianoaaiiuo kaʻina hoopiha i ke anuanu o Kahualoa Kokohi me ka pīlali kēpau me ke kiʻekiʻe dielectric ikaika, ka pale 'ana i ka mea hoʻololi uila mai kekahi ole mai o ke kaiapuni.

Hoolei'ōwili hao (i loko o ka olelo hoopomaikai ua'omoʻomoʻia pīlali kēpau)

Kēia mau mea i hoʻohui pū i ka'ōwili hao, encapsulated ma ka pīlali kēpau ma ke kaʻina hana o ka ho okumu. Ka mea i piha loa me ka kēpau ma lalo o holo.

Kēlā me kēia no ka o Kahualoa Kokohi'īpale i kūpono ua hōʻike hewa hoʻomākaukau ia no kekahi hana kūpono. He nui ke maopopo kahi pono e hoʻohana kūpono 'ano o na manao ona. No ka laʻana, maloo-type transformers me ka nou ana la o'īpale e ma kahi o 50% oi pipiʻi ma mua o ka huina hoonui VPE a VPI. Penei, i ke koho ana o kekahi mauʻano o ka mea hiki me ka nui loa pili i ka pono kāki o ka papahana.

Koi no ka koho i kekahi

Inā pono, mahuahua ia'ku i corona hookuuia (m. E. pou hookuuia, kena ae la ma ke kahua ikaika nui ae ma mua o ka ikaika dielectric o'īpale) ka wā hoonuiia me mechanical ikaika o ka o Kahualoa Kokohi ua i koi, hoʻohana VPI-type mea hoʻololi uila.

Hoʻohana ana i ka nou ana la o coils i kauoha hou ikaika a me ka maluhia, no ka laʻana, ma corrosive hana kūpono, e like me Nine Inch aaioee mea kanu, kanu kumuhana, e like me ka pono me ka foxmike mea hoʻonoho. Corrosive hana kūpono nā waiwai i i e detrimental i nāʻanuʻu a maloo-type transformers, me paʻakai, lepo, corrosive kinoea, ona a me ka mea hao (particles).

Eia hou, i ka o Kahualoa Kokohi me ka nou ana la o kēpau i ka hoonui ae i hiki ke pale aku i pōkole-makahiki a me ka repetitive overload ano o na mea he nui hanalima keʻano o ka hanaʻana.

Lunaʻenehana pinepine i ia e ke koho ma waena o ka mea me he nou ana la o kēpau ai kona VPI / VPE-'ano no ka hoʻohana i ka loa a me ka olelo corrosive hana kūpono. Keʻano mua ua ana noʻonoʻo i ka pono. Kekahi Manufacturers, nae, ka hōʻike i ka nou ana la o kēpau'īpale hoʻohaiki ana i ka hana ke ola o ka mea hoʻololi uila. Ke kaʻi lau waiwai o thermal? Anoe? Aiey o ka pīlali mea uuku ma mua ia o ke keleawe conductors. Cyclical? Aiey a me ka contraction ma ka hahana maoli nō kēia a me ka huʻihuʻiʻana coils hiki ultimately i ńlua o ke kēpau. Ua Ua pū kaulana i ka VPI-ʻano mea hoʻololi uila ke Makuakane maikaʻi me ia keʻano o ka hanaʻana, a no ia mea, mau hou. Ma ka hopena, i ka hope loa i waeʻia o ka mana lunaʻenehana.

Wai aʻano ku e maloo

Wai a-piha transformers, kamaʻilioʻana i ka i he oi aku ka hoʻokōʻana ma mua o maloo, no laila, ka mea, i ka hou ke ola. A, i ke kinowai meakino Ua oi ka hoʻokō e hoomaalili i nā wahi o ke kiʻekiʻe ana wela i loko o nāʻanuʻu. Eia kekahi, he wai-piha i na mea maalea i ka maikaʻi overload nona iho.

Penei, maloo 1000 kVA mea hoʻololi uila me ka hapalua haawe kiʻekiʻe o ka poho o ka hola 8 kW, a me ka piha - ma kahi o 16 kW. Pela o ka "tausani ka", akā, me ka wai a mea e pili ana i ka hapalua o neoneo. Oil "dvuhtysyachnika" ma ka hapalua o haawe poho he 8 kW, a me ka piha - 16 kW. Kona mea like maloo wehewehe aku koina 13 a me 26,5 kW, niioaaonoaaiii. Kēia 'o ia hoʻi i ka Poʻokela Honua i questionable maloʻo transformers malama i ka nui o ke poho. Lākou kumukuai i ka hookahi manawa kiʻekiʻe ma mua ia o ka wai.

Ma muli o ka nui mālama nui ka huʻihuʻiʻana loli o Kahualoa Kokohi lima kūlana kiʻekiʻe i liʻiliʻi Ana (hohonu a me ka laula) ma mua o maloo like nona iho. Ua hiki i ka hopena ma luna o ka mea e pono ai 'āpana o ka mea hoʻololi uila substations (oi loa kukulu-ma), a nolaila ke kumu o ka hale holoʻokoʻa. Penei, he typical maloo KVA mea hoʻololi uila 1000 i ka hohonu o 1,6 m + a me ka laula o ka 2,44 m. Ma keia hihia, i ka ia aila ina pono aku ka hohonu i ka laula o kahi o 1.5 m. Akā, i kēiaʻano loaa, nae, kekahi drawbacks.

No ka laʻana, ke ahi hoomalu Ua oi nui no transformers ka hoʻohana wai anuanu meakino i ka mea hiki ia o ke ahi. Eia naʻe, maloo-type transformers hiki i hopu i ke ahi. Improperly hoʻohana loli-type i hoʻomākaukauʻia e like explode.

Ke kaumaha ma muli o ka pae'ōnaehana olelo o ka wai-piha 'atikala e koi i ka pallet manaʻo no kaʻohiʻohi coolant ma kona hiki liu i.

Paha ka wā koho transformers hapa o ka hoʻololi mai i ka ike ana kāu mau koho i ka wai a maloo type mea ma waena o 500 kW, a 2,5 MVA, ai keʻano mua ua kaʻoi loa hoʻohana 'ia ma lalo huahelu, a me ka lua ma luna o ia.

An nui ololi i koho i keʻano o kekahi mea hoʻololi uila mea hoʻonoho wahi, e like me maloko, a mawaho o ka oihana hale, a me ka hoomau o ka hanalima wahie.

Maloo-ʻano transformers Loipālākiō ma oi ma mua o 5MVa hooholo koke loaʻa, akā, he nui wale o ia mau wai a-piha. No ka foxmike mea hoʻonoho, keia kekahi o na predominantʻano.

A mau olelo e pili ana i hoʻokomo ea

I ka wā i hoʻolako pono me ka wau peahi mea hoʻololi uila e haawe i me ka nui loa mahuahua ai. No laila, no ka nou ana la oʻanuʻu ia papa ke hoala mai i ka lōʻihi-makahiki haawe ana nona iho ma ka 50% ma luna o ka palena iki. No ka VPE a VPI-type mana waiwai i loko o keia hihia hiki e mai i ka 33%.

No ka laʻana, ka mea maʻamau mana mea hoʻololi uila kVA i 3000 me ka nou ana la o'ōwili hao a me kāna mau ipu ahi pńkaukau airflow piʻina i 4.500 kW (50%). I ka Ia manawa VPE- a VPI-type 2500 kVA nona iho me ke anuanu maila peahi hoala mai au ia ia 3.333 kW (33%).

Eia naʻe, kekahi e mau hoomanawanui ma ka manao i ke alo o ka wau ho'ēmi i kā ka pono pono o ke kahua. Inā 'oe e hana me ka puhi ma lalo o ka haawe ana ma luna ma mua o ka palena iki hoʻopuehu lākou i ke aloha, alaila, he mea kekahi maoli pilikia o ka mea ulia, like me ka hopena o i ka mea hoʻololi uila holoʻokoʻa hiki ke nalowale.

A me ka mea e pili ana i ka Lūkini kuai?

Ua mea waiwai 'ana i kumumanaʻo i loko o nā makahiki o ka napoo ka welelau o ia' oe i ka hana o Europe i hana i loko o Rusia, ma 90% o nā mea a pau transformers Puhi iho hoʻouka kekahi pili i keʻano maloo. Alaila, ke kuai reacts. I kēia lā i loko o Rusia he mau noi na manao maalea o ka pūʻulu elua o nā hoʻohua. Ka mua o kēia hiki nā Russian, Italian, Pākē a me ka Korean lama. Holo nōhie ia nā mall analogs o ka ike Lūkini ahi: piula wai, TSL, TSGL. Pehea ka nui o ka maloo mea hoʻololi uila? Price typical "tausani o" loli aʻe mai 900 tausani a hiki i 1 miliona rubles.

Ka lua o ka pūʻulu ka loaʻa o ka Kelemānia a me Palani nā hoʻohua. Ka mea, e kaumaha momoku ahi puke DTTH, GDNN, GDHN. I loko o ia ua lilo o ka mea i laweia mai mea hoʻololi uila? Ke kumukuai o ka ia "tausani ka" e ia mai ka 1.5 hiki i 2 miliona rubles.
