Ụzọ Nchedo Ise nke Ndị Nchedo Mberede

Ụzọ maka Nchedo Mbara Igwe

1. Ngwaọrụ Nchedo Mmegharị N'otu aka (SPDs) Ejikọtara n'ofe ahịrị ike

N'ọnọdụ nkịtị, varistors dị n'ime ihe nchebe surge na-anọgide na ọnọdụ high-impedance. Mgbe àmụ̀mà kụrụ grid ike ma ọ bụ nwee mmụba nwa oge n'ihi ọrụ mgbanwe, ihe nchebe ahụ na-azaghachi n'ime nanoseconds, na-eme ka varistors gbanwee gaa na ọnọdụ obere-impedance, na-ejide oke voltaji ngwa ngwa ruo n'ọkwa nchekwa. Ọ bụrụ na mmụba ma ọ bụ oke voltaji emee ogologo oge, varistor ahụ na-emebi ma na-ekpo ọkụ, na-akpali usoro njikọ okpomọkụ iji gbochie ọkụ ma chebe akụrụngwa.

2. Ihe Nchedo Mmụba nke Ụdị Nzacha nke Usoro Ejikọtara na Circuit Ike

Ndị nchekwa ndị a na-enye ike dị ọcha ma dị nchebe maka ngwa eletrọnịkị dị nro. Mmụba ọkụ eletrik anaghị ebu naanị ike dị ukwuu kamakwa oke voltaji na ọnụego mmụba ugbu a. Ọ bụ ezie na SPDs ndị yiri ya nwere ike igbochi oke mmụba, ha enweghị ike ịgbasa ihu ebili mmiri ha dị nkọ. SPDs ụdị nzacha usoro, nke ejikọtara na sekit ike, na-eji MOVs (MOV1, MOV2) iji jide oke voltaji na nanoseconds. Na mgbakwunye, nzacha LC na-ebelata oke voltaji na ọnụego mmụba ugbu a ihe fọrọ nke nta ka ọ bụrụ ugboro 1,000 ma na-ebelata voltaji fọdụrụ site na okpukpu ise, na-echebe ngwaọrụ ndị dị nro.

3. Ịwụnye ihe ndị na-eme ka voltaji dakọọ n'etiti usoro na ahịrị iji belata oke voltaji ndị na-arị elu

Usoro a na-arụ ọrụ nke ọma maka ọkụ, igwe mbuli elu, igwe oyi, na moto, nke nwere ikike iguzogide oke ọkụ. Agbanyeghị, ọ naghị arụ ọrụ nke ọma maka obere eletrọniki ọgbara ọhụrụ nwere njikọ dị elu. Dịka ọmụmaatụ, na sistemụ AC 220V nke otu-phase, a na-etinye varistors n'etiti etiti na ala iji nabata ọkụ eletrik ndị a kpaliri. Uru nchekwa dabere kpamkpam na nhọrọ varistor na ntụkwasị obi.

A na-etinye voltaji njide ahụ dabere na voltaji kachasị elu nke grid (310V), na-aza maka:
- Mgbanwe grid 20%,
- 10% nnabata nke ihe mejupụtara,
- Ihe ndị a pụrụ ịtụkwasị obi 15% (ịka nká, mmiri mmiri, okpomọkụ).
Ya mere, ọkwa njide nkịtị na-adị site na 470V ruo 510V. Oke okpomọkụ dị n'okpuru 470V na-agafe na-enweghị mmetụta ọ bụla.

Ọ bụ ezie na ngwa eletriki nkịtị (dịka ọmụmaatụ, moto, ọkụ) nwere ike iguzogide 1,500V AC (2,500V kacha elu), ngwa eletrọniki ọgbara ọhụrụ na-arụ ọrụ na ±5V ruo ±15V, yana oke nnabata dị n'okpuru 50V. Mkpọchi ugboro ugboro dị elu n'okpuru 470V ka nwere ike ijikọ site na ike parasitic na transformers na ihe ndị na-enye ike, na-emebi ICs. Ọzọkwa, n'ihi voltaji residual varistor na inductance lead, mmụba siri ike nwere ike ịkwalite ọkwa njide ruo 800V–1,000V, na-etinyekwu ihe egwu na ngwa eletrọniki.

4. Ime ka nchekwa dịkwuo mma site na iji Ultra-Isolation Transformers (Ultra-Isolation System)

A na-etinye transformer nkewapụ ihe nchebe n'etiti isi iyi ike na ibu iji gbochie mkpọtụ ugboro ugboro ma na-eme ka ntọala nke abụọ dị mma. Nnyefe ụdị nkịtị, nke metụtara ala, na-ejikọ site na ike ikuku dị n'etiti. Ihe nchebe ala n'etiti windings mbụ na nke abụọ na-eme ka nnyonye anya a ghara ịdị irè, na-ebelata mkpọtụ mmepụta.

5. Ụzọ Mmịpụta

Ihe ndị na-amịkọrọ ihe na-egbochi mmụba site na ịgbanwe site na oke mgbochi gaa na obere mgbe voltaji gafere oke. Ngwaọrụ ndị a na-ahụkarị gụnyere:
- Varistors – Ike njikwa ugbu a pere mpe.
- Ọkpọkọ Gas Refuge (GDTs)– Nzaghachi nwayọ.
- Diọdị TVS / Tubọọlụ Nwụpụ Dị Ike – Ọ dị ngwa ngwa mana ọ na-agbanwe agbanwe n'ịnara ike.
