Pehea e hoʻoponopono ai i ka pilikia kaapuni pōkole o Volvo Diesel Generator Set

ʻAʻole loaʻa ka pilikia kaapuni pōkole i ka wā o ka hoʻohana ʻana i nā pūnaehana hoʻoheheʻe ʻo Volvo.He aha nā kumu nui a pehea e hoʻoponopono ai?100KW mea hana generator kaʻana like me ʻoe.

1. ʻO nā hiʻohiʻona o ke kaapuni pōkole hikiwawe.

I ka hihia o ka steady-state short-circuit, ma muli o ka nui synchronous reactance, ka steady-state short-circuit current is not large, and in the case of a ulia pōkole-circuit, no ka mea, ka super-transient reactance limiting the liʻiliʻi kēia manawa a loaʻa i kahi ʻāpana o kēia manawa, nui ka manawa pōkole pōkole, hiki ke piʻi i kona kiʻekiʻe kiʻekiʻe ma mua o ʻumi mau manawa o ka manawa i helu ʻia.

Me ka puka ʻana mai o kēia manawa inrush, e hoʻokau ʻia nā wili o ka kaʻa i kahi mana electromagnetic hopena nui, hiki ke hoʻololi i nā makani a hiki ke hōʻino i ka insulation o nā makani.

I ke kaʻina o ka pōkole pōkole, ua hoʻokau ʻia ke kaʻa i kahi torque pōkole ikaika, a hiki ke haʻalulu.

He overvoltage ka stator a me ka rotor windings o ke kaʻa.

2. ʻO nā hiʻohiʻona o ke ʻano kino i loko o ka mīkini hana hana i ke kaapuni pokole.

I ka hihia o ke kaapuni pōkole paʻa, paʻa mau ke au o ka armature, a ʻo ka ikaika magnetomotive armature e pili ana i ka amplitude mau e hoʻololi ana i ke kahua magnetic e huli ana i ka wikiwiki synchronous, no laila ʻaʻole ia e hoʻoulu i ka ikaika electromotive i nā wili rotor a hoʻohua. kēia manawa.Mai ka pilina o kēia manawa Nānā, ua like ia me ke kūlana hamama o ka transformer.

Ke hiki koke mai ke kaapuni pōkole, hoʻololi ka nui o ke au o ka armature, a hoʻololi ke ʻano amplitude o ka armature magnetic field.No laila, hana ka mea hoʻololi ma waena o ka stator a me ka rotor, kahi e hoʻoulu ai i ka mana uila a me ka manawa i loko o nā wili rotor, a laila pili i nā wili stator.Mai ka manaʻo o ka pilina electromagnetic, ua like ka hoʻololi ʻana o ke au waena me ke kūlana pōkole pōkole o ka transformer.

I ka wā o ke kaʻina hana mana maʻamau o Volvo diesel generator set, ua pōkole pōkole nā ​​mea uila a ʻike ʻia kahi pōpō ahi nui, kahi i nalowale ai ka uila uila a me ka pinepine, a hoʻomaka hou ka mīkini diesel i ka wikiwiki helu, a ʻo ka generator. ʻaʻole hiki ke hoʻokumu i ka voltage.

Ke kālailai hāʻule:

Ma hope o ka ʻike ʻana o ka mea hoʻokele a i ʻole ka mea mālama i kahi hewa, pono lākou e nānā mua i ka fuse excitation, a laila e nānā i ka stator, exciter a me nā ʻāpana mana o ka generator.Ma hope wale nō o ka hōʻoia ʻana ʻaʻohe ʻāpana pōʻino hiki ke hoʻomaka ka mīkini diesel.Inā ʻaʻole hana ka mea hana i ka uila, pono ke nānā ʻia ke koena magnetization voltage o ka exciter.

Ke kumu o nā hewa:

(1) Aia kahi kaapuni hāmama a pōkole pōkole paha i loko o ka exciter.

(2) Wehe ʻia ka fuse hauʻoli.

(3) Nahaha o ka paipu lua.

(4) Aia kahi kaapuni pōkole a i ʻole kaapuni hāmama i loko o ka reactor.

(5) Nalo ke koena magnetism o ka exciter.

Ke ala hoʻoponopono:

Hoʻohana ʻia ka ʻāpana mana o kēia mīkini hana hoʻoheheʻe i ka phase compound excitation automatic voltage regulation, no laila i ka wā e hoʻoponopono ai i kēia ʻano hewa, pono ia e hoʻomaopopo i ke kumu o ka phase compound excitation automatic voltage regulation a me ka haku mele a me ke kuleana o kēlā me kēia sub-system, a laila e hahai i nā ʻanuʻu mai ka maʻalahi a i ke kumu o ka nānā paʻakikī.

(1) E nānā i ka fuse a ʻike ua puhi ʻia ka fuse.E nānā inā ua wela nā ʻāpana o ka pahu hoʻomalu.I ka wā o ka nānā ʻana, ʻike ʻia ua pau nā paipu ʻelua i kaupalena ʻia.

(2) E hoʻohana i ka multimeter no ke ana ʻana i nā diodes rectifier 6, a ʻaʻohe mea ʻino i loaʻa mai nā hopena hoʻāʻo.

(3) E hoʻohana i ka multimeter no ka hoʻāʻo ʻana i ke kūʻē o ka exciter, a ʻo ke kūpaʻa i ana ʻia ʻo 3.5Ω, e hōʻike ana i ka pōʻino o ka wili kūloko o ka exciter (ʻo ke kūpaʻa maʻamau ma kahi o 0.5Ω).

(4) Ma hope o ka hoʻololi ʻana i ka paipu palena palena ʻelua a me ka fuse, i ka wā e hoʻomaka ai ka mīkini diesel i ka wikiwiki i helu ʻia, ʻaʻole e hana ka mea hana uila.

Hōʻike kēia i ka hewa ʻo ka haʻahaʻa loa o ka volena remanence o ka exciter (i ke kaʻina hana o ka mana maʻamau, hiki koke i nā mea uila ke hele pōkole a ʻike ʻia kahi pōpō ahi nui, e hoʻoulu ai i ka volta remanence kūloko o ka exciter. e nalowale.

(5) Ma hope o ka magnetizing i ka exciter me ka pākaukau, e hoʻomaka i ka mīkini diesel i ka wikiwiki i helu ʻia, a hoʻomaka ka mea hana e hana i ka uila a hoʻokō i nā koi i kuhikuhi ʻia.

Inā makemake ʻoe i Nā mea hana hoʻoheheʻe Volvo , hoʻokaʻaʻike i ka hui ʻo Dingbo Power ma ka leka uila dingbo@dieselgeneratortech.com.
