Hoʻoholo ʻia ka mea insulation o ke kaʻa e ka nui o ka manawa a i ʻole ka volta?

ʻO ka hoʻokaʻawalemea waiwaio ke kaʻa i hoʻoholo ʻia e ka nui o ke au a i ʻole ka volta?

Mea hoʻokaʻawalehe mea nui koʻikoʻi no nā huahana kaʻa. ʻO nā kaʻa me nā pae uila like ʻole he ʻokoʻa nui i ke ʻano insulation o kā lākou wili a me kā lākou mau mea nui. No ka laʻana, ʻokoʻa loa ka ʻōnaehana insulation o ka mīkini kiʻekiʻe-voltage a me ka haʻahaʻa haʻahaʻa. .

Nā mea hoʻokaʻawale, ʻike ʻia ʻo dielectrics, he mau mea me ka resistivity kiʻekiʻe loa a me ka conductivity maikaʻi ʻole. Hoʻohana ʻia lākou i nā huahana kaʻa no ka maikaʻi o kā lākou conductivity. I nā huahana kaʻa, ma o nā mea insulating, ma ka ʻaoʻao hoʻokahi, pili nā uea conductive me nā mea ʻē aʻe. ʻO ka hoʻokaʻawale, ma ka ʻaoʻao ʻē aʻe, ʻo ia ka hoʻokaʻawale ʻana i nā wahi like ʻole o ka laina conductive, e like me ka insulation inter-turn a me ka insulation inter-phase. Hiki ke loaʻa nā waiwai like ʻole e like me ke kākoʻo, fixation, arc extinguishing, mildew resistance, radiation protection and corrosion resistance.

ʻO ka puhi ʻana o nā wili kaʻa he hōʻike paʻa o ka hōʻino ʻana a i ʻole ka nalowale ʻana o ka hana insulation. A laila, ua hoʻohaʻahaʻa ʻia ka hana insulation o ka kaʻa ma muli o ke kahe nui o ka makani a i ʻole ka uila kiʻekiʻe?

Ke nui loa ka ʻāwili ʻana o ke kaʻa, ʻo ke kiʻekiʻe kiʻekiʻe o kēia manawa e hoʻonui i ka pale ʻana o ka wili a hoʻoulu i ka wela nui. E hoʻopau ʻia ka wela i hana ʻia e ke kaʻa ma o ka insulation. Ke piʻi ka wela i kahi pae, e hoʻololi ʻia ke ʻano o ka mea insulating, e like me ke kaʻa.mea hoʻokaʻawalehiki ke pale aku.

No ka wili kaʻa, pili nā koi insulation ma waena o ka huli ʻana a me ka huli ʻana, ma waena o nā ʻano like ʻole o ka mīkini multi-phase, a ma waena o ka conductor a me ka lepo. Ke kiʻekiʻe ke kiʻekiʻe o ka volta o ke kaʻa, ʻoi aku ka kiʻekiʻe o ka volta o ka insulation wili, hiki ke noʻonoʻo i kēia me nā capacitors ʻokoʻa. Inā kiʻekiʻe loa ka volta ma waena o nā capacitors, e alakaʻi ia i ka pilikia o ka haʻihaʻi ʻana o ka capacitor, ʻo ia hoʻi, ka hāʻule ʻole o ka insulation o ke kaʻa kaʻa i ka honua, ma waena o nā huli a ma waena o nā pae.

From the above content, we can understand that although the current of the high-voltage motor is small, the insulation voltage of the windings is high, so a special insulation structure must be used to ensure that the electrical performance of the motor meets the requirements; while the low-voltage motor, because the insulation voltage is relatively high Therefore, the selection of insulating materials is relatively simple, but current density, ventilation and heat dissipation are the key factors to ensure the electrical performance of the motor. The current and voltage of the motor have different influences on the mea hoʻokaʻawalea pono e noʻonoʻo ʻia i ka manawa like.
