He aha ke kū'ē o ka stator winding o ka ʻekolu-phase asynchronous motor e manaʻo maʻamau ma muli o ka hiki?(No ka hoʻohana ʻana i ke alahaka a me ka helu ʻana i ke kūpaʻa e pili ana i ke anawaena uea, ʻaʻole kūpono ʻole ia.) No nā kaʻa ma lalo o 10KW, ʻo ka multimeter wale nō ke ana i kekahi mau ohms.No 55KW, hōʻike ka multimeter i kekahi mau hapaʻumi.E haʻalele i ka inductive reactance i kēia manawa.No ka motika hoku 3kw, ana ka multimeter i ke ku'e o ka wiliwili o kēlā me kēia māhele ma kahi o 5 ohms (e like me ka papa inoa ka'a, o kēia manawa: 5.5A. Mea mana = 0.8. Hiki ke helu 'ia Z=40 ohms, R =32 ohms).Nui loa ka ʻokoʻa ma waena o nā mea ʻelua.

Mai ka hoʻomaka ʻana o ka kaʻa a hiki i ka hoʻomaka ʻana o ka hana piha piha, holo ka motika no ka manawa pōkole a ʻaʻole kiʻekiʻe ka mahana.Ma hope o ka holo ʻana no 1 hola, piʻi maoli ka mahana i kekahi ʻano, e hāʻule nui ka mana kaʻa ma hope o hoʻokahi hola?Me he mea lā ʻaʻole!Ma ʻaneʻi, manaʻolana wau e hiki i nā hoa uila loea ke hoʻolauna i ke ʻano o kāu ana ʻana.Hiki i nā hoaaloha ke huikau i ka hoʻoponopono ʻana i nā kaʻa ke kaʻana like i kou hoʻomaopopo ʻana?

Hoʻohui i kiʻi e ʻike ai:

ʻO ke kū'ēʻana o ka wili wili ʻekolu o ke kaʻa e ana ʻia penei:

1. Wehe i ka ʻāpana hoʻohui ma waena o nā pauku kaʻa.

2. E hoʻohana i ka laulā haʻahaʻa haʻahaʻa o ka multimeter kikohoʻe e ana i ke kūʻē ma ka hoʻomaka a me ka hopena o nā wili ʻekolu o ke kaʻa.Ma lalo o nā kūlana maʻamau, pono e like nā kū'ē o nā wili ʻekolu.Inā he hewa, ʻaʻole hiki ke ʻoi aku ka hewa ma mua o 5%.

3. Inā ʻoi aku ka nui o ke kūpaʻa ʻana o ka motika ma mua o 1 ohm, hiki ke ana ʻia me kahi alahaka lima lima.Inā ʻoi aku ka liʻiliʻi o ke kūpaʻa wili kaʻa ma mua o 1 ohm, hiki ke ana ʻia me kahi alahaka lima ʻelua.

Inā nui ka ʻokoʻa o ke kūʻē ʻana ma waena o nā wili kaʻa, ʻo ia ke ʻano o nā wili kaʻa he mau pōkole pōkole, nā kaapuni hāmama, ka wiliwili maikaʻi ʻole a me nā hewa i ka helu o nā huli wili.

4. Hiki ke ana 'ia ka pale pale ma waena o nā wiliwili a me ka pale pale ma waena o nā wili a me nā pūpū e:

1) Ana 'ia ka motika 380V me ka megohmmeter me ke ana ana o 0-500 megohms a i ole 0-1000 megohms.ʻAʻole hiki ke emi mai kona pale insulation ma mua o 0.5 megohms.

2) E hoʻohana i ka megohmmeter me ke ana ʻana o 0-2000 megohms e ana i ka motika uila kiʻekiʻe.ʻAʻole hiki ke emi iho kona kūpaʻa insulation ma mua o 10-20 megohms.
