3. Ụzọ Nchọpụta Isi

3.1 Usoro Mmeghachi omume (Nrubeisi DL/T 1093-2018)

Ụkpụrụ: Na-atụ mgbanwe na reactance winding (impedance) n'okpuru voltaji AC iji chọpụta mgbanwe igwe.

Isi paramita:

Ugboro ugboro: 10 Hz – 1 MHz.

Izi ezi: ±0.5% maka uru impedance.

Voltaji ule: ≤2 kV (AC).

Uru: Nnukwu mmetụta uche maka obere mgbanwe (dịka ọmụmaatụ, 0.1% impedance division na-egosi nsogbu ndị nwere ike ime).

3.2 Nyocha nke Mmeghachi Omume Ugboro (FRA)

Usoro: Na-enyocha ugboro ugboro site na 10 Hz ruo 20 MHz iji jide njirimara resonance nke na-agbagharị agbagharị.

Mmelite JZP:

Nnwale dị elu: Isi data 50,000 maka nyocha ebili mmiri ziri ezi.

Nhazi mgbochi nnyonye anya: Mwepụ anya na ihe nchebe iji belata mkpọtụ elektrọnik.

Nsonaazụ: Nyocha ntụnyere nke spectra ugboro ole akụkọ ihe mere eme na nke ugbu a iji chọpụta mgbanwe na oke resonance (dịka ọmụmaatụ, mgbanwe >3 dB na-akpalite ịdọ aka ná ntị).

5. Usoro Nnwale

   5.1 Nkwadebe tupu ule

    

   Nyochaa akụrụngwa: Lelee nhazi sensọ (dịka ọmụmaatụ, eriri Rogowski maka akara ugboro ugboro dị elu).

    

   Ọnọdụ Transformer: Hụ na transformer ahụ anaghị enweta ike ma ọ bụ ntọala.

    

   5.2 Mmezu ule

    

   Nhazi waya:

    

   Mkpọchi mbụ: Tinye akara ule (dịka ọmụmaatụ, voltaji na-agbanwe agbanwe site na oghere mgbawa sekit).

    

   Ngagharị nke abụọ: Jikọọ ihe mmetụta iji tụọ akara ndị e tinyere n'ọrụ.

    

   Ntọala paramita:

    

   Usoro nyocha ugboro ugboro: Nkesa Logarithmic maka mkpuchi zuru oke.

    

   Oke ihe mkpali: Gbanwee onwe ya dabere na ikike transformer (dịka ọmụmaatụ, transformers 110 kV chọrọ mmetụta 100 ×).

    

   Inweta data:

    

   Were ihe nlele 200+ kwa ebe ugboro ugboro.

    

   Ngosipụta oge nke oke impedance/akụkụ nkebi.

    

   5.3 Nyocha Mgbe Ule Gasịrị

    

   Nchọpụta akpaaka:

    

   Tụlee ya na ntọala ụlọ ọrụ mmepụta ihe (dịka ọmụmaatụ, njigharị impedance karịa 2% na-egosi mgbanwe).

    

   Maapụ 3D nke nkesa nrụgide na-agbagharị agbagharị.

    

   Akụkọ: Mepụta akụkọ nrubeisi site na iji eserese na ndụmọdụ ndị a pụrụ ime.

    

   6. Ọmụmụ Ihe: Transformer nke ugbo ifufe

    

   Ihe atụ: Transformer ugbo ikuku nke nwere ike 33 kV gosipụtara 15% impedance dividence mgbe oké ifufe gasịrị.

    

   Ngwọta JZP:

    

   Emere nnwale FRA, na-ekpughe mgbanwe elu nke resonance 4 kHz.

    

   Achọpụtara m mgbanwe akụkụ nke na-agbagharị agbagharị site na onyonyo okpomọkụ 3D.

    

   Na-akwado ịlaghachi azụ, na-egbochi ọdịda nwere ike ịkpata ọdachi.

    

   7. Nrubeisi na Asambodo

    

   Ụkpụrụ mba ụwa: IEC 60076-18, IEEE C57.152.

    

   Asambodo: CE, UL, ISO 9001.

    

   Nkwenye nke ndị ọzọ: Nyocha kwa afọ site n'aka TÜV Rheinland.

    

   8. Mmechi

    

   Sistemụ nchọpụta mgbanwe nke JZP na-ejikọta nha ziri ezi, nyocha nke AI na-eduzi, na nrubeisi zuru oke na DL/T 1093-2018. Site na ijikọta teknụzụ kachasị ọhụrụ dị ka FRA ugboro ugboro na akụkọ akpaaka, anyị na-ahụ na transformers na-arụ ọrụ n'enweghị nsogbu na nke ọma n'ofe ọrụ ụwa niile.
