1 Taw qhia

Nrog lub transformation ntawm urban thiab nyob deb nroog grids hauv kuv lub teb chaws hwj huam kev lag luam thiab cov continuous txhim kho ntawm cov automation uas tsis muaj voltage fais fab tis lub nruab, qhib-hom transformers, Ua ib qho tseem ceeb hluav taws xob tivthaiv nyob rau hauv cov hwjchim uas tsis muaj hwj huam tis lub nruab, Ua si ib lub luag hauj lwm qhia tseem ceeb nyob rau hauv cov hwjchim grid transformation. Nws yog qhov ntau thiab cuab kev ntau cuab kev uas nws twb tau lug siv nyob rau hauv kev ntsuas, metering, relay kev tiv thaiv, lawv xyuas, Kev tiv thaiv thiab ntau yam hwj huam tsom xam.

tiam sis, Thaum installing qhib-hom low-voltage transformers tam sim no rau lub lag luam, Lub buckles yuav tsis tau fastened, Yuav ua rau cov tub ntxhais hlau yuav tsis raug kaw; Sab sauv thiab sab hlau tub ntxhais yuav tsis kaw, Raug rau cov transformer los yog tsis muaj tso zis tam sim no. Tus qhib-hom transformer nrog switching tus nqi yuav zoo noj rov qab qhov teeb meem no saum toj no rau qhov qhia los yog cov tom qab, thiab muaj sab kev thov prospects hauv hwj huam xyuas tej yaam num.

Ib transformer tam sim no transformer yog ib tug sensor siv los ntsuas alternating tam sim no

2. Ua hauj lwm tus thawj xibfwb ntawm transformer tam sim no transformer

Tus thawj xibfwb ua hauj lwm ntawm tus qhib low-voltage tam sim no transformer yog muaj nyob rau hauv daim duab 1.

Tus thawj winding ntawm tus qhib tam sim no transformer yog txuas nrog koob hauv kab hauv kev kuaj ntawd. I1 yog cov kab tam sim no, uas yog, Tus thawj tam sim no ntawm cov transformer tam sim no transformer, Thiab N1 yog pes tsawg tus thawj puv ntawm tus transformer tam sim no transformer. I2 yog tus theem nrab tam sim no ntawm tus transformer tam sim no transformer, N2 yog pes tsawg tus theem nrab puv ntawm tus transformer tam sim no transformer, Thiab Z2e yog tus impedance ntawm lub circuit Court circuit court thiab txuas nrog wires. Thaum tus thawj tam sim no flows hauv lub P1 davhlau ya nyob twg ntawm tus transformer tam sim no transformer thiab exits ntawm lub P2 davhlau ya nyob twg, Thaum lub secondary Z2e yog txuas nrog, Raws li tus thawj xibfwb ntawm electromagnetic induction, Cov theem nrab cua ntawm tus transformer tam sim no muaj ib tug tam sim no I2 ntws ntawm S1, Los ntawm Z2e rau S2, kaw loop.

Ntawm no, Nws yuav tau txais tias tam sim no yog I1×N1=I2×N2 hauv ib lub xeev zoo tagnrho, Ces I1/I2=N1/N2=K, Thiab K yog tus transformation piv ntawm tus transformer tam sim no transformer. tiam sis, Txij thaum cov hlau tub ntxhais ntawm tus qhib-hom transformer tam sim no transformer yog txiav, Cov kev kawm ntawm cov tub ntxhais hlau yuav loj dua, Li ntawd, tus ntoo khaub lig-seem ntawm cov tub ntxhais hlau ntawm tus transformer yuav tsum tau ntau zog, thiab cov ampere-puv yuav tsum tau ntau zog, thiab I1×N1=I2 ×N2≥100AN.

Tsis tas li ntawd, Rau tus nqi switching hloov ntawm tus transformer, Thaum lub buckle ntawm tus transformer yuav tsis muab tub kom zoo los yog lub casing yog lawm vim aging ntawm lub transformer, Lub khawm pops tuaj, Feem ntau kaw yuav qhib, lub teeb liab transmission yog terminated, Thiab cov transformer muaj tsis muaj teeb liab tso zis; Thaum lub buckle ntawm lub transformer yog ib qho zoo, Lub xeev hloov lub xeev yog feem ntau kaw, thiab cov transformer tej hauj lwm nquag.

3. Qhib hom transformer tam sim no transformer

Qhib-hom transformers mas siv nyob rau hauv nroog thiab nyob deb nroog grid reconstruction tej yaam num hauv kev lag luam. Nws yog characterized los ntawm yooj yim plahaum, Tsis muaj yuav tsum tau tshem cov tsheb thauj mus los, Thiab nws kuj yuav tau ua nrog hluav taws xob. tiam sis, Cov low-voltage qhib-hom transformers tam sim no rau lub lag luam muaj cov disadvantages:

(1) Tus qhib-hom transformer rau lub lag luam yuav tsis tau fastened los yog tus tub ntxhais hlau yuav tsis raug kaw thaum nruab nrab, thiab tej zaum yuav muaj ib qhov teeb meem ntawm lub transformer ntog los yog disconnecting thaum lub lag luam;

(2) Yog hais tias cov qhib-hom transformer yog artificially qhib rau ob zaug tom qab plahaum, yuav muaj teeb meem xws li tsis muaj teeb liab.

Aiming ntawm saum deficiencies, AKH-0.66/K-SW series tam sim no transformers yuav daws tau cov teeb meem saum toj no. No transformer muaj zoo nkauj zog, nruab nrab thiab maintenance. Raws li muaj nyob rau hauv daim duab 2, Tus transformer muaj cov nram qab no kom zoo dua:

Tam sim no Transformer Sensor khoom - Daim ntawv thov qhib-hom transformer nrog switching tus nqi

(1) AKH-0.66/K-SW series tam sim no transformers tsis tas yuav tsum tau disconnected thaum nruab nrab, thiab yuav tau ua nyob, thiab yuav muab ntsia ncaj qha mus rau ntawm qhov chaw tom qab kaw, txo cov nqi ua zog;

(2) AKH-0.66/K-SW series tam sim no transformer, muaj 4 hlau lead wires hauv no module, Ob wires transmit tam sim no teeb liab, thiab ob wires transmit hloov teeb liab;

(3) RAU AKH-0.66/K-SW series tam sim no transformers, Thaum lub buckle tsis muab tub los yog lub transformer yog aging, plhaub lawm, sab sauv thiab txo plhaub bounce tawm, Tus tub ntxhais hlau tsis nyob zoo, Thiab nws yog tua nyob rau sab plhaub ntawm lub transformer. Tsa ceg khawm ntawm tus hloov yuav pop upwards, Tus switch yog disconnected, thiab tus transmission ntawm tus nqi switch teeb liab yog terminated, Uas plays ib lub luag hauj lwm nyob rau hauv prompting qhib-hom tsawg-voltage transformer kom txhob ua hauj lwm.

(4) RAU AKH-0.66/K-SW series tam sim no transformers, Sab sauv thiab sab plhaub muaj hlau lead sealing qhov taub, Yuav tsum muab ntim tam sim ntawd tom qab plahaum.

4. Parameter sib piv cov lus

Tus emergence ntawm lub AKH-0.66/K-SW koob ntawm tam sim no transformers muaj functions xws li abnormal qhib tswb thiab qhia txog cov hwjchim-on thiab tua txheej xwm. Txoj kev loj hlob ceev ntawm txoj kev ua lag luam.
