Kōkua mākou i ka honua e ulu nei mai 2004

Nā hiʻohiʻona o nā mea hopu kuʻuna

1. ʻO ka mana o ka zinc oxide arrester he nui
Hōʻike nui ʻia kēia i ka hiki i nā mea hopu uila ke ʻimi i nā overvoltages uila, nā overvoltages transient o ka manawa pinepine, a me nā overvoltages e hana nei. ʻO ka hiki i ke kahe o ka zinc oxide arrester i hana ʻia e Chuantai e hoʻokō piha a i ʻole ʻoi aku i nā koina o nā kūlana aupuni. ʻO nā mea hōʻike e like me ka pae hoʻokuʻu laina, ka hiki ke komo i ka ikehu, 4/10 nanosecond kiʻekiʻe i kēia manawa ka hoʻomanawanui, a me 2ms ʻāpana nalu i hiki i ka pae alakaʻi kūloko.

2. ʻO nā ʻano palekana maikaʻi loa o nā mea hoʻopaʻa i nā oxide zinc
ʻO Zinc oxide arrester kahi huahana uila i hoʻohana ʻia e pale ai i nā pono uila i ka ʻōnaehana mana mai ka poino o ka ikaika, a he hana palekana maikaʻi. Ma muli o ka maikaʻi o ka volt-ampere ʻano ʻole o ke kinikini kiwikā zinc oxide, no laila hiki i kekahi mau haneli microampere ke hele ma lalo o ka uila hana maʻamau, maʻalahi ka hoʻolālā ʻana i kahi hanana gapless, no laila he palekana maikaʻi hana, ke kaupaona māmā, a me ka liʻiliʻi liʻiliʻi. hiʻona. Ke hoʻouka ka nui o ka uila, ke piʻi wikiwiki nei ke kahe i loko o ka pā kiwikā, a ma ka manawa like e kaupalena ʻia ai ka nui o ka uila, a hoʻokuʻu ʻia ka ikehu o ka uila Ma hope o kēlā, hoʻi ka pā kīwaha zinc oxide i kahi kūlana kūpale kiʻekiʻe, i hana maʻamau ai ka ʻōnaehana mana.

3. Maikaʻi ka hana sila ʻana o ka zinc oxide arrester
Hāʻawi ka mea arrester i kahi lākeke ahupapa kiʻekiʻe me ka maikaʻi o ka hana ʻelemakule a me ka airtightness maikaʻi, a me nā ana e like me ka kaohi ʻana i ke kaomi o ke apo hoʻopaʻa a hoʻohui i ka sila. Hoʻohana ʻia ka pālolo pālolo ma ke ʻano he mea sealing e hōʻoia i ka hoʻopaʻa pono ʻana a me ka hana paʻa o ka arrester.

4. ʻO nā pono mechanical o nā mea hopu i ka oxygen zinc
E noʻonoʻo nui i nā mea aʻe ʻekolu:
Force Ka ikaika ōlaʻi;
⑵ʻO ke kaomi makani kiʻekiʻe e hana ana ma ka arrester
⑶ ʻO ka wēlau o luna o ka arrester ke lawe i ka palena i ʻae ʻia o ka uea.

5. Ka hana decontamination maikaʻi o zinc oxide arrester
ʻO ka arrester zinc oxide arress gapless kahi kūpale kiʻekiʻe.
ʻO ka pae o ka mamao creepage i hōʻike ʻia e ka pae ʻāina.
⑴Kahi II ʻāpana hoʻohaumia waena: mamao loa o 20e / kv
⑵ III ʻāpana polū kaumaha: ka mamao o ka creepage 25mm / kv
⑶ Papa IV, ʻāpana haumia nui loa: ka mamao o creepage 31mm / kv

6. ʻoi aku ka hilinaʻi kiʻekiʻe o ka mea hopu i nā oxide zinc
ʻO ka hilinaʻi o ka hana lōʻihi e pili ana i ka maikaʻi o ka huahana a inā he kūpono ke koho ʻana o ka huahana. Hoʻopili nui ʻia ka maikaʻi o kāna huahana e nā ʻano ʻekolu aʻe:
H. Ke kūpono o ke ʻano holoʻokoʻa o ka arrester;
B Volt-ampere mau ʻano a me nā kūpale kūpale kūpale o nā kinikini oxide zinc
C Ka hana sila o ka arrester.

7. Ka hoʻomanawanui pinepine ʻana
Ma muli o nā kumu like ʻole e like me ka pae ʻana o ka pae hoʻokahi, ka hopena capacitance laina lōʻihi a me ka hoʻoiho hoʻoiho i ka ʻōnaehana mana, e hoʻonui ia i ka uila pinepine a hana paha i ka overvoltage transient me ka amplitude kiʻekiʻe. Hiki i ka arrester ke kū i kekahi mana pinepine i loko o kekahi mau manawa. Hoʻonui i ka hiki i ka uila
