6-220kV elu voltaji reactor
Ndị na-emepụta ihe
A na-eji reactor, nke a makwaara dị ka inductors, na sekit. N'ihi mmetụta induction electromagnetic, enwere ụfọdụ ogo inductance na sekit, nke nwere ike igbochi mgbanwe mgbanwe ugbu a. Mgbe onye nduzi na-enye ume, a na-emepụta oghere magnetik n'ime oghere ụfọdụ ọ dị, ya mere ndị na-eduzi ọkụ eletrik niile dị ugbu a nwere mmetụta zuru oke nke inductance. Otú ọ dị, inductance nke onye nduzi ogologo na ogologo dị ntakịrị, na oghere magnetik emepụtara adịghị ike. Ya mere, n'ezie reactor bụ waya ọnya n'ụdị solenoid, nke a na-akpọ oghere reactor;
Mgbe ụfọdụ, iji mụbaa inductance nke solenoid a, a na-etinye eriri ígwè n'ime solenoid, nke a na-akpọ reactor iron core. A na-ekewa mmeghachi omume n'ime reactance inductive na reactance capacitive. Nhazi nke sayensị ọzọ bụ na a na-akpọkarị reactance inductive (inductor) na capacitive reactance (capacitor) dị ka ndị nrụpụta. Otú ọ dị, n'ihi ịdị adị nke inductors n'oge gara aga, nke a na-akpọ reactors, capacitors ugbu a na-ezo aka dị ka capacitive reactances, na reactors kpọmkwem na-ezo aka inductors.
Ihe reactors ndị a na-ejikarị na sistemu ike gụnyere usoro reactors na reactors ndị yiri ya. Series reactors na-tumadi-eji amachi mkpụmkpụ-circuit iyi, na nwekwara ike jikọọ na usoro ma ọ bụ yiri capacitors na nzacha na-amachi elu-usoro harmonics na ike okporo. A na-eji ndị na-emepụta ihe na 220kV, 110kV, 35kV, na 10kV ike grids na-etinye ike na-emeghachi omume site na eriri eriri n'oge ịchaji. Enwere ike ịhazi voltaji arụ ọrụ site n'ịgbanwe ọnụ ọgụgụ nke reactors yiri ya. Ultra elu voltaji yiri reactors nwere dị iche iche ọrụ iji melite arụ ọrụ ọnọdụ metụtara reactive ike na ike usoro, tumadi gụnyere: 1. The capacitance mmetụta na ejighị ya kpọrọ unloaded ma ọ bụ ejighị ya kpọrọ ahịrị iji belata transient overvoltage na ike ugboro; 2. Meziwanye nkesa voltaji na ahịrị nnyefe dị anya; 3. Iji dozie ike reactive na akara dị ka o kwere mee na saịtị n'oge ibu ọkụ, na-egbochi enweghị ezi uche eruba nke reactive ike na mbenata ike ọnwụ na akara; 4. Belata voltaji na-adịgide adịgide nke ike ugboro ugboro na ụgbọ ala voltaji dị elu mgbe nnukwu unit dị na usoro ahụ, na-eme ka ọ dịkwuo mfe maka generator na-ejikọta ya na ya; 5. gbochie onwe excitation resonance onu nwere ike ime na generators nwere ogologo ahịrị; 6. Mgbe iji a reactor na-anọpụ iche ebe site a obere reactance grounding ngwaọrụ, a obere reactor nwekwara ike-eji na-akwụ ụgwọ maka frasi na-adọ na-adọ na ala capacitance nke akara, iji mee ngwangwa akpaka extinguishing nke latent ugbu a na ikwado ojiji ya. Enwere ike kewaa wiring nke reactors ụzọ abụọ: njikọ usoro na njikọ yiri ya. Series reactors na-eje ozi dị ka ugbu a ịmachi ngwaọrụ, mgbe yiri reactors na-ejikarị maka reactive ike akwụ ụgwọ.
