Nā ʻokoʻa i nā ʻano hoʻāʻo ma waena o ka mea hōʻike kūʻē kūʻē a me ka mea hōʻike kūʻē i ka lepo
(1) Keʻano ho'āʻo o ka mea hōʻike kū'ē kū'ē
ʻO ka mea hōʻike kū'ē kū'ē i ka ho'āʻoʻana i ka degere o ka hoʻokaʻawaleʻana ma waena o nā pae, nā papa a me nā kikoʻole o nā uea a me nā kaula.ʻOi aku ka kiʻekiʻe o ka waiwai hoʻāʻo, ʻoi aku ka maikaʻi o ka hana insulation.Hiki ke ana ʻia ke kū ʻana o ka insulation e UMG2672 Electronic Megohmmeter.
(2) Ke Ana Ho'āʻo o ka Grounding Resistance Tester
ʻO ka mea ho'āʻo kū'ē i ka honua he mea hana mana eʻike ai inā kūpono ke kū'ēʻana.ʻO ke ʻano o ka hoʻāʻo ʻana o ka Grounding Resistance Tester, ʻo ia ka mea i hoʻopili ʻia ka lako uila i ka mana like e ka honua, a ʻo ia hoʻi ka pili ʻana o ka uea hana a i ʻole ka mea hoʻokele uila i ka honua.ʻO ka waiwai i ana ʻia e ka Grounding Resistance Tester kahi ana kūpono e hōʻoia ai i ka palekana pilikino.Hiki iā ʻoe ke koho i ka DER2571 Digital Grounding Resistance Tester i hana ʻia e WeiA Power.
ʻEhā, ʻO ka ʻokoʻa kumu ma waena o ka Insulation Resistance Tester a me ka Ground Resistance Tester
(1) Ke Kumu o ka Insulation Resistance Tester
Ke hoʻohana ʻia ka Insulation Resistance Tester no ke ana ʻana i ke kūpaʻa ʻana, ua hoʻopili ʻia ka DC Voltage U i ka Insulation.I kēia manawa, hoʻololi ke ʻano o kēia manawa i ka hoʻemi ʻana i ka manawa, a ʻo ka hope e lilo i kahi waiwai paʻa.
ʻO ka mea maʻamau, ʻo ke ʻano o kahi mea hōʻike kūʻokoʻa insulation ka huina o ka mana o kēia manawa, absorption i kēia manawa a me ka hoʻoiho ʻana i kēia manawa.Capacitive Current Ic, Kona Attenuation Speed He wikiwiki loa;'Oi aku ka lohi ma mua o ka mana o kēia manawa iaδc;Conduction Inp o kēia manawa, ʻo ia ka mea e kūpaʻa i kahi manawa pōkole.
I ka wā o ka hoʻāʻo ʻana me ka hoʻohana ʻana i ka Insulation Resistance Tester, inā ʻaʻole pulu ka Insulation a maʻemaʻe ka ʻili, e pohō koke nā ʻāpana o kēia manawa Ic a me Iaδc i ka Zero, e waiho wale ana i kahi hoʻokaʻawale liʻiliʻi o kēia manawa e hala, no ka mea, ʻo ke kū ʻana o ka insulation i hoʻololi. Hoʻohālikelike ʻia me ka ʻāwīwī i kēia manawa, e piʻi koke ke kūpaʻa insulation a paʻa i kahi waiwai nui.Eia naʻe, inā pulu ka Insulation, piʻi nui ke ʻano o ka hoʻoiho ʻana, ʻoi aku ka wikiwiki ma mua o ka waiwai mua o ka absorption au Iaδc, ua hoʻemi nui ʻia ka mea kū i kēia manawa, a ua haʻahaʻa loa ka waiwai kūʻē i ka insulation, a ua loli nui me ka manawa.Micro.
No laila, i ka hoʻokolohua o ka Insulation Resistance Tester, ʻo ka maʻemaʻe o ka insulation i hoʻoholo ʻia e ka Absorption Ratio.Ke ʻoi aku ka nui o ka absorption ratio ma mua o 1.3, e hōʻike ana ʻo ia ka maikaʻi o ka insulation.Inā kokoke ka ratio absorption i ka 1, e hōʻike ana ia ua pulu ka insulation.
(2) Ke Kumu o ka Papa Kū'ē Kū'ē
Kāhea ʻia ʻo Grounding Resistance Tester ʻo Grounding Resistance Measering Instrument, Grounding Shaker.ʻO ke kumu ho'āʻo o ka ho'āʻo kū'ē'āinaʻo ia ka loaʻaʻana o ka waiwai kū'ē'āina "Rx" ma o ka AC mau o kēia manawa "I" ma waena o ka Electrode Ground "E" a me ka Electrode Power Supply "H(C)" o ka mea i lalo o ka ho'āʻo, A ʻIke ʻia ke kahua ʻokoʻa "V" ma waena o ka Electrode "E" a me ka Electrode Ana "S(P)".
