ʻIke pōkole o ka GIS Partial Discharge Detection Method

ʻO nā hopena noiʻi o kēia manawa no ka hoʻokuʻu ʻana i ka hapa i nā lako GIS e hōʻike ana ma muli o ka ikaika dielectric kiʻekiʻe o ke kinoea SF6, ʻo ka lōʻihi o ka hoʻokuʻu hapa pulse i ke kinoea SF6 kiʻekiʻe i nā lako GIS he pōkole loa, e pili ana i kekahi mau nanoseconds, a. pōkole loa ke poʻo nalu.ʻO ka manawa piʻi ma kahi o 1ns wale nō.ʻO kēia ʻano puʻupuʻu kiʻekiʻe me ka lōʻihi pōkole loa, me nā hōʻailona a hiki i GHz, e hoʻopuka i nā nalu electromagnetic e kahe ana ma ka pahu lako GIS.Ke kahe nei ka pulse hoʻokuʻu kiʻekiʻe ma o ka uwea kumu, a pili ka pahu i ka honua.Hāʻawi i ka uila alapine kiʻekiʻe a hoʻopuka i nā hawewe electromagnetic ma ke ākea a puni.ʻO ka hoʻokuʻu hapa ʻana e hoʻonui koke i ke kaomi o ke kinoea awāwa, e hoʻohua i nā nalu longitudinal a i ʻole nā ​​hawewe kani ultrasonic i ke kinoea o nā mea hana GIS, a me nā hawewe kani like ʻole, e like me nā nalu longitudinal, nā nalu transverse a me nā nalu ʻili, ʻike ʻia ma ka metala pūpū.Hiki i nā hoʻokuʻu hapa ʻana i nā mea hana GIS ke hoʻoheheʻe a hoʻokuʻu paha ke kinoea SF6.ʻO kēia mau hoʻololi kino a me ke kemika i hui pū ʻia me ka hoʻokuʻu hapa ke kumu no ka ʻike pūnaewele o nā lako GIS.Hiki ke hoʻokaʻawale ʻia nā ʻano ʻike o ka hoʻokuʻu hapa ʻana i nā lako GIS i ʻelua mau ʻāpana: ke ʻano ʻike uila a me ke ʻano ʻike ʻole uila.ala, SF6 kinoea decomposition huahana ike ala.

GDPD-300UF UHF Hoʻokuʻu hapa ʻImi

Hiki ke hoʻohana nui ʻia ka HV Hipot GDPD-300UF UHF (UHF partial discharge instrument) i ka ʻike ʻana o nā ʻōnaehana mana, me nā mea hoʻololi kiʻekiʻe volage, nā apo nui, nā mea hoʻololi uila / kēia manawa, transformer (me ka maloʻo Insulation state detection of nā mea hana e like me nā transformers), GIS, nā laina ma luna, nā kaula, a me nā mea ʻē aʻe, ke ana ʻia ka pae hoʻokuʻu o nā mea uila e nā mea hōʻike.

Nā hiʻohiʻona o ka UHF Partial Discharge Detector

E hoʻonohonoho i nā mea ʻike like ʻole no ka loaʻa ʻana o ka ʻike hoʻokuʻu hapa o nā lako uila āpau;

ʻO ka mea hoʻohana-aloha kanaka-mīkini hoʻomaʻamaʻa i ka mālama ʻana i ka ʻikepili o nā lako like ʻole, me ka traceability o nā ʻikepili mōʻaukala, ka nānā ʻana i ka ʻikepili ākea a me ke kūpaʻa, a ʻike i ka 360 ° ka hōʻoia piha o nā mea hana ma lalo o ka hoʻāʻo;

ʻO ka sensor kani ultrasonic i kūkulu ʻia a me ka volter ground transient (i kapa ʻia ʻo TEV) sensor, hiki ke hoʻopili ʻia i nā mea ʻike kūikawā e like me nā transformers, GIS, nā laina ma luna, a me nā kaula;

Hoʻohana ʻia ke ʻano ʻike ʻole invasive, ʻaʻohe hemahema o ka mana i ka wā o ka hoʻāʻo ʻana, a ʻaʻohe kumu kiʻekiʻe kiʻekiʻe e koi ʻia, ʻoi aku ka maʻalahi o ka hoʻohana ʻana ma mua o ka pulsed partial discharge detector;

ʻO ka laulā bandwidth hōʻike he 30kHz ~ 2.0GHz, kūpono ia no ka ʻike ʻike o nā ʻano alapine like ʻole.
