Hōʻike huahana
He kūpono ke ʻano o GKG no ka hoʻohana ʻana i nā mine lanahu me ka ʻole o ke kinoea, nā pōʻino pahū o ka lepo lanahu a me nā keʻena uila like ʻole e like me nā mines non-coal.ʻO GKG ʻano maʻamau kiʻekiʻe-voltage switchgear no ka mining (ma hope i kapa ʻia ʻo switchgear), i hoʻohana nui ʻia i loko o ka hale kaʻa ma lalo o ke kinoea a me ka lepo lanahu i loko o ka lua, ke ala nui ea inlet a me ka lumi hāʻawi mana o ke alanui inlet ea.E like me AC 50Hz, ka uila 7.2KV a i ʻole 12KV lako uila e hāʻawi ana i ka laina komo, feeder, pale a me ka hoʻomalu ʻana i nā kaʻa uila kiʻekiʻe, nā mea hoʻololi.Hiki ke hoʻohana ʻia ʻo Switchgear i nā substations mine ground a me ka lako mana a me nā ʻōnaehana hoʻoili i ka metallurgy a me nā ʻoihana kemika.

Nā hiʻohiʻona huahana a me ke kaiapuni hana
1. Ua lanakila ka mea hoʻololi i nā hemahema o ka mea hoʻololi mua.ʻO ka mīkini lima lima lima hou i hoʻomohala ʻia e ka hui he mau hana pale piha, hilinaʻi kiʻekiʻe o ka hana, a me ka mālama maʻalahi a maʻalahi.ʻO ka liʻiliʻi liʻiliʻi a me ke kaumaha māmā.
2. ʻO ke keʻena hoʻololi i haku ʻia me kahi keʻena a me kahi kaʻa lima.Ua māhele ʻia ʻo ia i keʻena kaʻa lima, ke keʻena busbar, ke keʻena uwea, a me ke keʻena relay e ka pā.ʻElua kūlana o ke kaʻa lima no ka hoʻokolohua a me ka hana.Hoʻokaʻawale ʻia ke keʻena kaʻa lima mai ke keʻena uwea e kahi pā hoʻoneʻe insulating, kahi kūpono a palekana i ka wā mālama.ʻO 100% ka uku hoʻololi o ke kaʻa lima, e hōʻemi ana i ka manawa mālama a hoʻomaikaʻi i ka maikaʻi o ka mana.He pololei a maʻalahi ke ala paheʻe o ke kaʻa lima e hōʻoiaʻiʻo ʻaʻole e haʻalele ke kaʻa lima i loko a i waho, a ua hoʻokomo ʻia kahi kaʻa hoʻokele hoʻonohonoho i mea e hoʻopili pololei a hilinaʻi hoʻi ka pahu lua.
3. ʻO ka hana pale o ka switchgear, ma hope o nā makahiki o ka hoʻohana ʻana i nā mines lanahu, hiki i ka huahana ke hālāwai me nā koho pale o nā kumu like ʻole, i lako me ka leakage, ka nānā ʻana i ka insulation, undervoltage, pōkole pōkole, overcurrent overvoltage overvoltage, a hiki ke hoʻohana pū ʻia me ka mana mamao, kamaʻilio mamao, telemetry, a me nā mea ʻē aʻe. Hiki ke hoʻolako ʻia ka mīkini pale ʻakomi piha me kahi mea koho laina hoʻomalu honua liʻiliʻi.
Hiki ke koho ʻia ke ʻano o ka pale microcomputer mining a me ke ana a me ka mana.Loaʻa i ka ʻōnaehana pale kahi pilina kamaʻilio.Hoʻouna ʻia nā ʻike āpau i ka nānā ʻana a i ʻole ka ʻōnaehana hoʻoponopono i ka manawa maoli ma o ka pūnaewele kamaʻilio."Elima mamao" hana.
Nā hana pale nui:
1) Pale kaapuni pōkole
2) Hoʻomalu overload
3) ʻO ke kaʻina Zero ka pale ʻana i ka overcurrent
4) Zero sequence overvoltage pale
5) Overvoltage a me ka undervoltage pale
Loaʻa iā ia nā hana e like me ka hoʻomanaʻo hewa, ka nīnau hewa, a me ka nānā ponoʻī.
