6kV-220kV Pā

ʻO nā huahana nui i hanaʻia e ka hui:

12kV ~ 252kV pulupulu impregnated puluniu capacitive paia bushing;

12kV ~ 252kV capacitive composite paia bushing;

12kV ~ 252kV capacitive porcelain paia bushing;

40.5kV ~ 252kV maloʻo-ʻano kiʻekiʻe-voltage paia bushing me kēia manawa transformer;

35kV ~ 126kV maloʻo ʻano kiʻekiʻe voli i kēia manawa transformer;

10kV ~ 35kV hoʻohui capacitive coupler;

Loaʻa i kā mākou hui ka ikaika ʻenehana ikaika, ʻenehana kiʻekiʻe, ʻōnaehana hoʻokele kūpono, nā lako nānā maikaʻi piha, a me ka huahana R&D ikaika a me ka mana hana. E pili ana i ka philosophy pāʻoihana o "market-oriented, quality as life, management as fundamental, science and technology first, people-oriented", ke kākoʻo nei ka hui i ka moʻomeheu ʻoihana o ka pono, ka hana hou, ka pono a me ka lokahi, lawelawe i ka hui me ka kiʻekiʻe- nā huahana maikaʻi a me nā kumukūʻai kūpono, a hoʻokō i nā pono like ʻole o nā mea kūʻai aku. Hoʻokaʻawale ʻia ka ʻoihana ʻoihana o ka ʻoihana ma nā pae āpau o nā pahu mana a me nā papahana ikehu nui ma Kina, a hāʻawi i ka kiʻekiʻe kiʻekiʻe silicone rubber composite insulation kākoʻo huahana no nā mea hana uila kaulana honua.

2、 Hoʻolauna huahana

ʻO Fcrgj glue impregnated fiber capacitive wall bushing e hoʻemi mālie i ka uila kiʻekiʻe ma o ke kumu hoʻokaʻawale capacitive voltage. Ma ka hana maʻamau, ua like ke alakaʻi pale hope me ka flange a hoʻopaʻa ʻia ma o ka flange. I hiki i ke alakaʻi kiʻekiʻe-voltage ke hele i ka paia a i ʻole ka papahele me ka palekana a pāʻani i ke ʻano o ka insulation a me ke kākoʻo ʻana i ka diversion.

Hoʻokumu ʻia ia me ka wili mua, ka puʻu o waho, ka pale umbrella silicone, ka uhi hoʻohālikelike ʻana i ke kaomi ma nā wēlau ʻelua, flange a me ke kaula uea conductive.

3 、Paʻa pā

No ka laʻana, ʻo ka manaʻo o fcrgj-24 / 3150: rubber impregnated fiber capacitive wall bushing me ka helu helu o 24kV a me ka helu o kēia manawa o 3150A.

ʻO ka manaʻo o fcrgj-252 / 2500: kāpili i hoʻopaʻa ʻia i ka fiber capacitive wall bushing me ka voltage helu o 252kV a me ka helu o kēia manawa o 2500A.

4. Hoʻohana i nā kūlana:

1. Kūlana ea ambient: ambient ea wela: maximum 55 ℃, liʻiliʻi - 60 ℃.

2. E hoʻokō ke koho ʻana i kahi mamao kikoʻī me nā ʻōlelo o GB / T 5582.

Hoʻokaʻawale ʻia ka mamao kikoʻī Creepage i 4 mau pae:

Papa I: 16mm / kV; Papa II: 20mm / kV; Papa III: 25mm / kV; Papa IV: 31 mm / kV

ʻO ka hewa maikaʻi ʻole i ʻae ʻia o ka mamao kolo maoli o ka puʻupuʻu ʻo 0.04l + 1.5mm (L: ka mamao creepage nominal liʻiliʻi).

Inā ʻaʻohe koi o ka mea hoʻohana, ʻo 31mm / kV ka paʻamau

5、 Nā palena ʻenehana nui o ka huahana

1. Hāʻawi ka papa 1 i ka volta helu, ka uila hana ʻōnaehana, ka helu ʻana i kēia manawa, ka pae insulation a me nā ʻāpana ʻē aʻe o ka pā ʻano ʻano fcrgj.

2. Ma lalo o ka volta o 1.05ur / √ 3 a me ur, ke kumu poho dielectric TG δ ≤0.4%.

3. Loaʻa ka hiki ke hoʻokuʻu kūloko: ≤ 5pc ma lalo o ka voltage helu o 1.05ur / √ 3.

4. Piʻi wela ≤ 60K, hana lōʻihi ma ka helu inom o kēia manawa

5. Keia manawa pale wela: ith = 25inom, 3C

6. ʻO nā kūlana ʻenehana ʻē aʻe e kūlike me nā kūlana IEC 60137-2017 a me GB / T 4109-2008 insulating bushings me ka volta AC ma mua o 1000V.

6、 Ka lawe ʻana a me ka hāpai ʻana

1. Ka halihali huahana

1.1 hiki ke lawe ʻia nā huahana ma ke kaʻaahi, moku, kaʻa, mokulele a me nā ʻano ʻē aʻe. Pono e hoʻomaʻemaʻe ʻia ka ʻāpana kaʻaahi, ke keʻena moku a me ke keʻena kaʻa e lawe ana i nā huahana a me ka ʻole o nā mea haumia.

1.2 ʻO ka hoʻouka ʻana o nā huahana e hoʻokō i nā koi i nā lula o ka halihali, a e hoʻokau paʻa ʻia nā huahana. ʻAʻole ʻae ʻia ka haʻalulu, ka hui ʻana a me ka neʻe ʻana i ka wā o ka lawe ʻana.

1.3 i ka wā o ka lawe ʻana i nā huahana, ʻaʻole ʻoi aku ka nui o ka makemake ma mua o 30 °.

1.4 ma hope o ka hoʻoili ʻia ʻana o nā huahana ma ka uwapo kikowaena a i ʻole ka hoʻokuʻu ʻia ʻana ma ke kikowaena, ʻaʻole e ʻoi aku ka hoʻopaʻa ʻana ma mua o ʻekolu papa, a ʻaʻole ʻae ʻia nā mea ʻē aʻe e hoʻopaʻa ʻia me lākou.

HEADING-TYPE-1

He kūpono nā capacitor parallel voltage kiʻekiʻe no ka hoʻohui like ʻana i nā ʻōnaehana mana AC me ke alapine mana (50Hz a i ʻole 60Hz) o 1kV a ma luna. Hoʻohana ʻia lākou e uku no ka mana inductive reactive, hoʻomaikaʻi i ka mana kumu, hoʻomaikaʻi i ka maikaʻi o ka volta, hōʻemi i nā poho laina, a hoʻohana piha i ka pono o ka hana mana a me nā lako lako.
