ʻEhiku mau hiʻohiʻona o ka mea hoʻopaʻa ZINC OXIDE

1. Ka mana kahe

Hōʻike nui ʻia kēia i ka hiki o ka mea hopu ke omo i nā overvoltage uila like ʻole, nā overvoltage transient alapine mana, a me nā overvoltage hana.

2. Nā hiʻohiʻona palekana

ʻO ka mea hopu zinc oxide kahi huahana uila i hoʻohana ʻia e pale i nā lako uila like ʻole i loko o ka ʻōnaehana mana mai ka pōʻino overvoltage, a he hana pale maikaʻi kona. Ma muli o ka maikaʻi loa o nā ʻano nonlinear volt-ampere o ka papa valve zinc oxide, he mau haneli microamperes wale nō o ke au e hiki ke hele ma lalo o ka voltage hana maʻamau, he mea kūpono ia e hoʻolālā i kahi ʻano hakahaka ʻole, i loaʻa iā ia ka hana pale maikaʻi, māmā a liʻiliʻi ka nui. hiʻohiʻona. Ke komo mai ka overvoltage, piʻi koke ke au e kahe ana ma o ka papa valve, a i ka manawa like, ua kaupalena ʻia ka amplitude o ka overvoltage, a hoʻokuʻu ʻia ka ikehu o ka overvoltage. Ma hope o kēlā, hoʻi ka papa valve zinc oxide i ke kūlana kū'ē kiʻekiʻe, i hiki i ka ʻōnaehana mana ke hana maʻamau.

3. Hana sila

Hoʻohana ka ʻāpana arrester i kahi ʻaʻahu hui kiʻekiʻe me ka hana ʻelemakule maikaʻi a me ka paʻa ʻana o ka ea. Hoʻohana ʻia nā hana e like me ka kaohi ʻana i ke kaomi ʻana o ke apo sila a me ka hoʻohui ʻana i ka sealant. Hoʻohana ʻia ka ʻaʻahu keramika ma ke ʻano he mea sila e hōʻoia i ka sila hilinaʻi a me ka hana paʻa o ka arrester.

4. Nā waiwai mīkini

ʻO nā kumu ʻekolu e noʻonoʻo nui ʻia: ka ikaika seismic e hoʻomanawanui ʻia; ke kaomi makani kiʻekiʻe loa e hana ana ma ka arrester; ka ikaika tensile kiʻekiʻe loa i ʻae ʻia o ke kaula ma luna o ka arrester.

5. Hana hoʻomaʻemaʻe

He kiʻekiʻe ke kūpaʻa o ka mea hopu zinc oxide gapless i ka haumia.

ʻO ka lakio kolo i kuhikuhi ʻia e ke kūlana aupuni: Papa II wahi haumia waena: lakio kolo 20mm/kv; Papa III wahi haumia kaumaha: lakio kolo 25mm/kv; Papa IV wahi haumia kaumaha loa: lakio kolo 31mm/kv.

6. Hilinaʻi hana kiʻekiʻe

ʻO ka hilinaʻi o ka hana lōʻihi e pili ana i ka maikaʻi o ka huahana a inā kūpono ke koho ʻana o ka huahana. ʻO ke ʻano o ka huahana e hoʻopilikia nui iā ia, ʻo ia nā ʻano ʻekolu: ke kūpono o ke ʻano holoʻokoʻa o ka mea hopu; nā ʻano volt-ampere a me nā ʻano anti-kahiko o ka pā valve zinc oxide; ka hana sila o ka mea hopu.

7. Ka hoʻomanawanui alapine mana

Ma muli o nā kumu like ʻole i loko o ka ʻōnaehana mana, e like me ka hoʻokumu ʻana i ka pae hoʻokahi, ka hopena capacitance laina lōʻihi a me ka hōʻole ʻana i ka ukana, e piʻi aʻe ka voltage alapine mana a i ʻole e hana ʻia kahi overvoltage transient me kahi amplitude kiʻekiʻe. Loaʻa i ka arrester ka hiki ke kū i kahi alapine mana i loko o kekahi manawa. Ka hiki ke hoʻonui i ka volta.
