ʻO Morteng grounding carbon brushes nā mea nui i nā kaʻa kaʻa kaʻa (e like me nā mea hana a me nā kaʻa uila), hoʻohana mua ʻia e hoʻopau i nā au o ka shaft, pale i ka palekana o nā lako, a kōkua i nā ʻōnaehana nānā. ʻO kā lākou mau hiʻohiʻona noi a me nā hana penei:
I. Core hana a me nā hopena
- Ke holo nei ka mīkini hana a i ʻole ke kaʻa, hiki i ka asymmetry ma ke kahua magnetic (e like me ka ʻae ʻole o ka ea a i ʻole nā ʻokoʻa o ka coil impedance) hiki ke hoʻoulu i ka volta shaft i ka ʻau kaʻa. Inā haʻihaʻi ka volta shaft i ka kiʻiʻoniʻoni ʻaila bearing, hiki iā ia ke hana i ka shaft current, e alakaʻi ana i ka shaft bearing electrolysis, lubricant degradation, a me ka hāʻule ʻole.
- Hoʻopili pōkole ʻo Morteng grounding carbon brushes i ke kumu rotor a hiki i ka hale mīkini, e hoʻohuli i nā au o ke kumu i ka lepo a pale iā lākou mai ke kahe ʻana i nā bearings. No ka laʻana, hoʻokomo maʻamau nā mea hana nui i nā pulupulu kalapona hoʻokumu ʻia ma ka hopena turbine, ʻoiai ua hoʻokomo ʻia nā bearings hope excitation me nā pads insulating, e hana ana i ka hoʻonohonoho 'excitation end insulation + turbine end grounding'.
II. Nā hiʻohiʻona noi maʻamau
- Nā mea hoʻomohala wela / wai wai: Hoʻokomo ʻia nā pulupulu kalapona Morteng grounding ma ka hopena turbine, i hui pū ʻia me nā bearings insulated ma ka hopena excitation, e hoʻopau i ka leakage magnetic induction shaft voltage. No ka laʻana, i loko o ka hydropower generators, thrust bears hilinaʻi wale ma luna o kahi kiʻiʻoniʻoni ʻaila lahilahi no ka insulation, a ʻo ka hoʻopaʻa ʻana i nā pulupulu kalapona hiki ke pale i ka electrolysis o nā pūpū lawe.
-Wind turbines: Hoʻohana ʻia no nā rotors generator a i ʻole nā ʻōnaehana pale pale, koho pinepine ʻia nā mea mai ka metallic graphite (copper/silver-based), e hāʻawi ana i ka conductivity kiʻekiʻe, ke kūpaʻa ʻana, a me ke kūpaʻa transient o kēia manawa.
- ʻO nā motika kiʻekiʻe-voltage/variable-frequency: ʻoi aku ka nui o kēia mau pilikia o ke au o ka shaft. No ka laʻana, ua hoʻokomo ʻo Tonghua Power Generation Company i nā pulupulu kalapona paʻa ma ka hopena hoʻokele o ka mīkini peʻahi mua, me ka hoʻohana ʻana i nā pūnāwai kaomi mau no ka mālama ʻana i ka hiki ʻole, a laila e hoʻoholo i ka pilikia ʻaʻole hiki i nā bearings insulated kumu ke hoʻopaʻa loa i kēia manawa.
-Kaʻa kaʻaahi: Ma nā kaʻa kaʻa o nā locomotives uila a i ʻole nā locomotive diesel, hoʻopau nā pulupulu kalapona i ka hoʻopaʻa ʻana i ka uila i ka wā o ka hana, pale i nā bearings, a mālama i ka paʻa o ka ʻōnaehana uila.
