Series EVT / ZW32-10 Voltage Transformers
Derating
Series EVT/ZW32--10 voltage transformers yog ib hom tshiab ntawm high voltage ntsuas thiab tiv thaiv transformers, feem ntau txuam nrog sab nraum zoov ZW32 nqus Circuit Court breaker.Cov transformers muaj lub zog muaj zog, lub teeb liab me me tso tawm, tsis tas yuav hloov pauv PT thib ob, thiab tuaj yeem txuas ncaj qha rau cov khoom siv thib ob los ntawm kev hloov pauv A / D, uas ua tau raws li kev txhim kho ntawm "digital, ntse thiab networked" thiab "integrated automation system. ntawm substation".
Cov yam ntxwv ntawm tus qauv: Qhov voltage ntawm no series ntawm transformers txais capacitive los yog resistive voltage division, epoxy resin casting, thiab ib tug silicone roj hmab tes tsho.
■Integates tam sim no thiab voltage ntsuas thiab tiv thaiv teeb liab tso zis, thiab ncaj qha outputs me me voltage signals, simplifying lub system qauv thiab txo qhov yuam kev.
■ Tsis txhob muaj cov tub ntxhais hlau (lossis muaj cov tub ntxhais hlau me), yuav tsis saturate, dav zaus teb ntau, ntsuas ntau yam, zoo linearity, muaj peev xwm tiv thaiv kev cuam tshuam, nyob rau hauv qhov system txhaum lub xeev tuaj yeem ua rau cov cuab yeej tiv thaiv kev lag luam txhim khu kev qha.
■ Thaum lub qhov hluav taws xob tso zis hluav taws xob yog luv luv rau lub sijhawm thib ob, tsis txhob tsim cov overcurrent, thiab tsis muaj ferromagnetic resonance, uas tshem tawm cov kev txhaum loj zais kev phom sij hauv kev ua haujlwm ntawm lub zog hluav taws xob thiab ua kom muaj kev nyab xeeb ntawm cov neeg ua haujlwm thiab cov khoom siv.
■ Ntau lub zog, me me, lub teeb yuag, kev siv hluav taws xob tsawg, txo cov pa phem ferromagnetic

Txoj kev teeb tsa
Built-in transformer hauv Circuit Court breakers thiab kho nws tsis tu ncua ntawm lub bracket
Lub tshuab hluav taws xob txuas nrog cov cuab yeej hluav taws xob lossis cov cuab yeej tiv thaiv los ntawm kev sib xyaw shielded cable, thiab cov ntaub thaiv npog cable yog grounded los ntawm grounding software los yog hlau mounting puag.
Dimensions nyob rau hauv millimeters
Ordering Information
Thaum txiav txim, thov sau cov qauv khoom, qhov tseem ceeb ntawm cov khoom siv (cov ntsuas hluav taws xob, qib raug, ntsuas qhov ntsuas thib ob) thiab ntau.yog tias muaj cov cai tshwj xeeb, thov sib txuas lus nrog lub tuam txhab
