N'ime ọrụ nrụpụta ụlọ nyocha dị elu, ọrụ bụ isi nke sistemu ọdịda ahụ bụ ime ngwa ngwa ezighi ezi, gbochie nnyonye anya elektrọn ma hụ na nchekwa nke ndị ọrụ na akụrụngwa. Ọrụ ya na-emetụta izi ezi nke nnwale na nchekwa ọrụ.
A na-eji ntupu ọla gbasawanye ọla kọpa dị ọcha n'ọnọdụ a n'ihi njirimara ihe pụrụ iche na uru nhazi ya:
1.Pureucing Grounding Resistance:A na-eme ntupu igwe gbasachara site na stampụ na ịgbatị efere ígwè, nwere akwa akwa (ntupu rhombic nkịtị nwere oghere 5-50mm). Ebe elu ya dị 30%-50% buru ibu karịa nke efere ọla kọpa siri ike nke otu ọkpụrụkpụ, na-abawanye mpaghara kọntaktị na ala nke ọma ma na-ehichapụ kọntaktị kọntaktị.
2.Uniform ugbu a omume:Nrụpụta nke ọla kọpa dị ọcha (≥58 × 10⁶ S / m) dị elu karịa nke igwe galvanized (≤10 × 10⁶ S / m), nke nwere ike ịgbasa ngwa ngwa ma na-eme ajọ mmiri dị ka ntapu akụrụngwa na ọkụ na-adaba n'ime ala, na-ezere ikike dị elu nke mpaghara.
3. Na-adaba na mbara ala mgbagwoju anya:Ntupu igwe gbasaara nwere ụfọdụ mgbanwe ma enwere ike ịtọ ya na ala (dị ka mpaghara nwere nnukwu ọkpọkọ n'okpuru ala na ụlọ nyocha). Ka ọ dị ugbu a, ntupu Ọdịdị adịghị egbochi penetration nke ala mmiri, ịnọgide na-enwe ogologo oge ezi kọntaktị na ala.
4.Enwere ike nhata:Igwe ọkụ dị elu nke ọla kọpa dị ọcha na-eme ka enwere ike nkesa n'elu akwa ntupu igwe gbasaa, na-eme ka voltaji kwụ ọtọ (na-achịkwa voltaji nzọụkwụ n'ime uru nchekwa nke ≤50V).
5. Mkpuchi siri ike:Enwere ike igbutu ntupu igwe gbasasịrị ma gbasaa n'ime nnukwu mpaghara (dịka 10m × 10m) na-enweghị oghere na-agbapụ, na-ezere mmụgharị mpaghara nwere ike ime, ọkachasị dabara maka mpaghara nnwale nwere nnukwu akụrụngwa voltaji dị elu.
6.Electric Field Shielding:Dịka oyi akwa mkpuchi igwe, ntupu ọla gbasasịrị ọla dị ọcha nwere ike iduzi ọkụ eletrik kpafuru akpafu nke emere site na nnwale n'ime ala site n'itinye ala, na-asachapụ nnyonye anya mpaghara eletrik na ngwa.
7.Mgbakwunye Magnetic Field Shielding:Maka oghere magnetik dị ala (dị ka 50Hz ike ugboro magnetik), ọ bụ ezie na nnukwu magnetik permeability nke ọla kọpa dị ọcha (permeability ≈1) adịghị ike karịa nke ihe ferromagnetic, njikọ njikọ magnetik nwere ike ịda mbà site na "nnukwu mpaghara + ala na-eguzogide ala", karịsịa kwesịrị ekwesị maka ugboro ugboro na nnwale voltaji.
Ọcha ọla kọpa dị ọcha gbasaa nchara ígwè, ya na njirimara ya nke ịdị elu dị elu, nguzogide corrosion siri ike, na mpaghara kọntaktị buru ibu, na-ezute n'ụzọ zuru oke ihe achọrọ nke ụlọ ọrụ voltaji dị elu maka usoro ala nke "nkwụsi ike dị ala, nchekwa, ịdị irè ogologo oge, na mgbochi nnyonye anya". Ọ bụ ihe dị mma maka ịkụda grids na nhata grid. Ngwa ya nwere ike melite nchekwa nnwale yana ntụkwasị obi data, yana ụgwọ mmezi ogologo oge nke Pureuce.
