Kedu usoro mwepu ziri ezi ka emechara ule AC Hipot?

Emere ule hipot, ma gbanyụọ HV. Enwere m ike ibili metụ ibe nnwale ahụ aka?

Ọ bụghị kpamkpam. Ike echekwara n'ime ihe nlele ahụ nwere ike ịnwụ: E=½ × C × V². Ọmụmaatụ: 50 nF na 100 kV=250 Joules (ọnụ ụzọ egbu egbu ≈ 10 J).

Usoro nchụpụ 7 nke amanyere iwu (IEEE 510 §5.3):

Nzọụkwụ	Omume	Ogologo oge	Ihe kpatara ya
1	Belata ọkọnọ HV na efu (gbadata)	2–3 s	Na-egbochi voltaji overshoot
2	Gbanyụọ ọkọnọ HV, kwupu ike ntinye	Ngwa ngwa	Na-egbochi re-ike
3	Chere (mwepu onwe-nwere ike)	Karịrị ma ọ bụ hà nhata 60 s	Ọbara mbụ na-agbapụta site na ndị na-egbochi ọbara ọgbụgba
4	Tinye osisi n'ala nwere resistor na HV	Jide 10 s	Mwepu achịkwara na-amachi ọ̀tụ̀tụ̀ dị ugbu a
5	Bugharịa mkpanaka ahụ gaa n'ebe ala kacha nso	2–3 s	Na-akwado na ike ala
6	Mkpụkpọ - okirikiri & ala HV + LV yana akwa ọla kọpa	Hapụ ebe	Na-egbochi fanye site na absorption
7	Chere 2 min → nyochaa na onye na-achọghị kọntaktị	Karịrị ma ọ bụ haha na nkeji 2	Dielectric absorption voltaji mgbake

Nkọwa osisi grounding:

• Ogwe mkpuchi nke akwadoro maka voltaji ule. Ihe mgbochi mkpofu: 5-20 kΩ.

• eriri ala: 16–35 mm² braid braid, ogologo na-erughị ma ọ bụ hà nhata na 5 m.

Ntinye dielectric (voltaji mgbake):

• Mkpuchi akwụkwọ/mmanụ re-na-eweghachi ụgwọ → ọnụ ahịa nwere ike iweghachite 20–40% nke voltaji ule n'ime nkeji 1–2.

• Ntupu → chere 2 min → lelee → ma ọ bụrụ na enwetara voltaji, wepụ ọzọ.

• Tinyegharịa ruo mgbe voltaji na-anọ <50 V mgbe nkeji 2 gachara.

Ọ dịghị mgbe:

❌ Metụ ọdụ ụgbọ mmiri HV ozugbo ọ kwụsịrị.

❌ Jiri screwdriver/obere waya ka ọ dị mkpụmkpụ-circuit HV (arc + shockwave na-achịkwaghị achịkwa).

❌ Mwepu na-enweghị usoro resistor (mmebi ụdị + arc flash).

❌ Were ya na a chụpụrụ USB/TX onwe ya{0}} ka nkeji iri atọ gachara (ogologo eriri: 5–30 min).
