Ka Mahi te Ārai Ngaru me te kore he Whenua?

I mātakitaki ahau i tētahi parai parai $3,000 i roto i taku ake tari nā te mea kāore he whenua tūturu o te "surge strip". Kei te mamae tonu ōku kanohi i taua paoa.

Kāo, kāore e taea e te parenga ngaru te tiaki i ō taputapu mēnā kāore he waea whenua tūturu i te putanga pakitara; ahakoa ka tukuna tonutia te hiko, kāore he wāhi haumaru hei haere atu mō te kaha ngaru kino.

Pānuihia tonu, ā, māku e whakaatu ki a koe te take i kore ai e iti te titi ngaro, me pēhea taku whakamātautau i ngā kōhao i roto i te toru tekau hēkona, me taku mahi ina kore te whare tawhito e tuku i te whenua ki ahau.

Me pēhea te mahi a te Kaitiaki Ngaru?

Kei te maumahara tonu ahau ki te haruru o te uira i te pānga o te uira ki te tuanui o tō mātou hoa noho. Ko taku whakaaro tuatahi, "Tukua te MOV i roto i taku rīpene kia kanikani."

Ka panaia te ngaohiko tāpiri e te parenga ngaru ki te waea whenua mā te Metal-Oxide Varistor; ki te kore taua ara putanga, ka noho tonu te pūngao ki roto i tō ara iahiko, ā, ka tahuna te maramara ngoikore rawa.

Ko te wāhanga iti e hopu ana i te matā

I roto i ia rīpene ka kitea e koe tētahi, neke atu rānei ngā MOV. Kei waenganui i te ora me te whenua, te koretake me te whenua. I te 130 V ka piri, engari ka mahi noa te piri mena kei te tatari te whenua, pērā i te waikeri tuwhera.

Mā ngā joules koe e whakaatu te rahi o te peere

Ka whiriwhiria e au ngā rīpene he 600 J te iti rawa mō taku paepae taiwhanga, me te 2,000 J mō ngā whata tūmau. E whakaatu ana te ripanga i raro nei i te maha o ngā ngaru ka taea e te MOV noa te horomia i mua i te hurihanga hei pereki waro.

He aha te hiranga o te waea matomato i te tapanga whakapiri

Ahakoa kei roto i te rīpene te UL 1449, kāore tonu e taea. Kua whakatuwheratia e au ngā pae "tohu-CE" kāore he pine whenua i runga i te mono. I whakapirihia te MOV ki tētahi pine kirihou rūpahu. Ka kitea e te ngaru te ara pai e whai ake nei—he maha ngā wā mā te taura Ethernet me te papahoahoa o tō pona.

Taku whakamātautau pūwero e rua meneti te roa

I mua i taku mono i tētahi mea utu nui, ka whakamahia e au he taputapu whakamātautau $3. Me tiaho ngā rama e toru. Ki te pōuri te mea o waenganui, ka waea atu ahau ki te tohunga hiko, ka nekehia rānei e au te whatanga. Kāore rawa ahau e whakawhirinaki ki te kupu a te rangatira whare e mea ana, "He pai pea."

He aha te mea ka tupu ina mate te MOV

Kāore ngā MOV e ora. Whai muri i te pānga nui, ka piki ake te ngaohiko o te rawhi. I tētahi rā, ka nui ake te ngaru i te MOV ngenge, ā, ka peke te pūngao ki roto i tō pūtake hiko. Ka whakawhiti au i ngā rīpene i ia toru tau i te whenua uira, i ia rima tau i hea atu.

Kua honoa ngā parenga ngaru katoa ki te whenua?

I ako au i te ara uaua, kāore te tapanga "puku" i runga i te pouaka e tohu ana he pine whenua kei te pae; ko ētahi ka tiaki noa i ngā raina raraunga, ka waiho tahanga te ara hiko.

Kāo, he maha ngā parenga ngaru hiko iti-haere me ngā parenga ngaru hiko e rua-pine kāore he hononga whenua; ka whakawhirinaki rātou ki te herenga raina-kore, ā, he wāhanga noa iho te tiakitanga e tukuna ana.

Te mahi tinihanga hokohoko i tinihanga i ahau

I te tau kua hipa i hokona mai e au tētahi pae ma kanapa mō tētahi whakaahua. E rua noa iho ngā pine o te mono. Ko ngā tuhinga iti i tuhia "te tiaki i ngā ngaru i waenga i ngā rārangi". He āwhina tēnā ki ngā ngaru iti, engari ka pana tonu te uira i te 6 kV ki runga i te anga.

Tēpu whakapiri rua-titi

He aha ahau ka whakamahi tonu ai i ngā pae titi-rua

Ka whakamahia e au, engari mō ngā rama me ngā rihi waea anake. Ka tapaina e au ko "NO GROUND—NO PRICY GEAR" kia kore ai aku akonga e mono i te oscilloscope ki roto.

Te rohe hina: ngā putanga GFCI

He putanga GFCI ā ētahi taiwhanga tawhito, kāore he mokowā whenua. Mā te GFCI koe e whakaora, engari kāore e taea te neke atu i te ngaru hiko. Ka tāpirihia e au tētahi kōwae MOV motuhake kua honoa ki tētahi whenua paipa wai ina tutuki tēnei whakaritenga.

Ngā Tūponotanga me ngā Āwangawanga Haumaru o te Whakamahi i ngā Tiaki Ngaru Kore Whenua

I te 2 karaka i te ata ka hongi ahau i te kirihou e mura ana; kāore he whenua o te ara hiko, ā, ka puta te ngaru hiko mā te taura USB-C, ka honoa taku pona ki te tēpu.

Ki te kore he whenua, ka taea e te kaha ngaru te piko ki roto i te whiri, te mura i te kirihou, te haere rānei mā roto i ngā taura whatunga ka whakangaro i ngā taputapu hono katoa.

Ka tīmata te ahi i roto i te kirihou

Ka wera ngā MOV. Ka tukuna te wera me ngā irahiko e te rīpene whenua. Ka mau te pūngao e te rīpene kāore i te whenua. Kua kite ahau i te pereti mata e pupuhi ana, e maturuturu ana pērā i te tiihi i runga i te paraharaha.

Te ara huna i roto i te Ethernet

I ine ahau i te 1,800 V i waenga i ngā pona e rua e whakamahi tahi ana i tētahi rīpene kore whenua. I eke te ngaru ki runga i te taura CAT6, ā, i pakaru ngā NIC e rua. He nui ake te pire whakatika i te tau mō ngā pae ngaru.

Te tūponotanga o te ru tangata

Ina kore he whenua o te ngaru hiko, ka taea e te pouaka whakarewa o tō rorohiko te piki ki te haurua o te ngaohiko raina mō ngā maikorohekona. He roa rawa tēnā hei ru i a koe mēnā ka pā koe ki te pouaka me te whenua tūturu i te wā kotahi.

Taku matihiko mōrearea mō ngā kaihoko

Me pēhea te tirotiro me te whakarite kia tika te whenua o te parenga ngaru

Kei roto i te pūtu o taku pona he taputapu whakamātautau rama-toru; nā tēnei i whakaora ahau i ngā papa parai i roto i ngā whenua e rima me te tini o ngā tari reti.

Monohia he whakamātautau putanga māmā ki roto i te putanga hiko; me ōrite ngā rama e toru ki te tūtohi kei runga i te whakamātautau, ki te kore ka tuwhera te whenua, ā, ka noho noa iho tō parenga ngaru hiko.

Taku tirotiro tirohanga rima hēkona

Ka rapua e au te kōhao porowhita. Ki te ngaro, ka mutu. Ki te mea kei reira engari he kirihou, ka mutu tonu. He iti ake te utu o te kōhao whenua rūpahu i te parahi, ā, he koretake anō hoki.

Te whakamahi i te mita maha mō te kaihoko whiriwhiri

Whakatakotoria te mita ki te VAC. Ko te tohu o te hiko ora ki te korekore me rite ki te 110–125 V. Ko te tohu o te hiko ora ki te whenua me rite tonu. Ko te tohu o te hiko korekore ki te whenua me 0–2 V. Ki te kore he tau kē atu, ko te tikanga kei te ngaro te hiko whenua, kei te hē rānei te tohatoha.

Te tinihanga o te paipa wai

I roto i tētahi whare putunga o ngā tau 1950, i herea e au tētahi waea parahi ki tētahi paipa wai matao, ā, i tukuna ki te whatanga. I inehia e au te 0.3 Ω ki te whenua o te panera. He pai rawa atu tēnā mō ngā mahi ngaru hiko, engari ka tapaina tonutia e au ko te "whenua aux".

Tuhia te whakamātautau

Ka tangohia e au he whakaahua o ngā rama whakamātautau ka tāpirihia ki te ota mahi. Ina mate tētahi taraiwa $50,000, ka hiahia te kaiinihua ki te taunakitanga i mahia e au taku mahi.

Me pēhea te whakatakoto tika i te parenga ngaru ki te whenua

I tētahi wā ka werohia e au he tokotoko parahi e waru putu te roa mā roto i te papa raima me te whakamahi i tētahi wiri hama i riihitia; nā te mura o te waea i taku whakamāu i te waea i whakaatu mai kua maha ngā tau e mānu ana te whare i te 40 V.

Whakahaerehia he waea matomato 12 AWG mai i te hononga whenua o te parenga ngaru ki te hononga whenua matua o te whare, ki tētahi tokotoko rānei kua whakaaetia; kia poto ake te oma i te tekau putu, ā, whakamahia ngā hononga kua kōpiko, kaua e miro.

Taku tunu mara taahiraa-i-te-taahiraa

1. Whakawetohia te pūwete.
2. Wetekina te ¾ inihi o te whakamarumaru.
3. Whakapikohia te pūtu kotahi-kōhao ki te taputapu waipēhi.
4. Whakawirihia te taura ki te papa whenua mā te whakamahi i te mīhini whakamāori whetu.
5. Te taipana ki te 25 in-lb.
6. Me tapa te waea me te tohu “Surge EQ GND” kia mōhio ai te tohunga hangarau e whai ake nei he aha i noho ai i reira.

Ina kore e taea te whakatuwhera i te papa

Ka whakamahia e au tētahi pouaka SPD o waho e mau ana ki te taha o te panera, ā, ka kawea mai he titi whenua ki waho. Ko te parenga ngaru i roto i te pouaka he 10 AWG te taura. Ka tāpirihia e au he urunga raka-hurihuri kia taea ai te whakawhiti i te rīpene i roto i te toru tekau hēkona.

Ripanga utu mō ngā kōwhiringa whenua

Taku whakamātautau hinengaro whakamutunga

Kia oti, ka mono anō ahau i te taputapu whakamātautau. Kātahi ka whakakāhia e ahau he whakamahana 1,500 W, ka mātakitaki i te ngaohiko kore-ki-te-whenua. Ki te piki ake i runga ake i te 2 V, ka whakakahangia e ahau ia hononga kia heke rawa.

Te rapu i tētahi Rōpū Tiaki Ngaru Ngaio — leikexing Manufacturer

I te tono a taku kiritaki Tiamana mō te 5,000 SPD 32 A ritenga me ngā putanga IEC C19 i roto i ngā rā tekau, ka tukuna a leikexing i roto i te iwa; i moe pai ahau i taua pō.

E mahi tahi ana ahau me Leikexing nā te mea he 2,000 m² te rahi o tā rātou tipu i Wenzhou, e tuku ana i te ratonga mekameka tuku katoa, ā, e whakautu tonu ana i aku īmēra i roto i te haora kotahi—ahakoa ka tono ahau mō tētahi putanga 690 V delta rerekē.

He aha i mutu ai taku hokohoko haere

I mua, e toru ngā wheketere i wehea e au ngā ota. Nā ngā whakaroa, ngā tapanga whakauru, me ngā MOQ i porangi ai ahau. Mā te leikexing ka taea e au te whakaranu i ngā tauira 20 A, 30 A, me te DC ki roto i te puranga kotahi, 500 ngā wahi. Mā tēnā ka whakaitihia taku utu utanga mā te 18%.

Aku tuhipoka arotake i te papaanga

I rere ahau ki Wenzhou i te marama o Poutū-te-rangi. I kite ahau i ngā MOV whaimana UL kua whakatakotoria ki roto i ngā kāpata e whakahaeretia ana te makuku, ngā taraiwa taipana aunoa e tuhi ana i ia tīwiri, me tētahi whata wera e pā ana ki ia waeine ki te 6 kV e toru ngā wā. I tuhituhi ahau i te kupu "PASS" ki taku pukapuka.

Ngā ratonga e homai ana e rātou kia taea ai e au te hoko atu

- Arotake DFMA i roto i ngā haora 48

- Tānga laser mō taku waitohu, kore utu, i raro i te 500 ngā wahi

- Ngā tuhinga RoHS me REACH kua tāpirihia ki roto i te kātene

- He huinga moana-hau ina tomuri ahau

He pepa taipitopito tere ka tukuna atu e au ki a Jeff Weaver

Ko te MOQ he 100 ngā wahi mo ia tauira, 500 ngā wahi katoa. Ko te wā tuku he 15 ngā rā, 30% te moni tāpui, 70% ki te kape BL. E whakaaetia ana e rātou te T/T, te Alibaba Trade Assurance rānei.

Whakamutunga

Ehara i te mea whiriwhiri te whenua; ko te hoa puku te mea e kaha ana ki te whawhai. Whakamātauria ia pūwero hiko, whakahaerehia he waea tūturu, ka whiriwhiri i tētahi wheketere e tuku ana i te wā tika—e kore tō ngaru hiko e tatari.
