PS-ZK03 Transformator Kortsluiting Impedansie Tester

Die kortsluitimpedansie is 'n belangrike parameter van die transformator, en die kortsluitimpedansiemetode is die tradisionele metode om wikkelvervorming te beoordeel. Volgens GB1094.5-2003 en IEC60076-5:2000 is die variasie van kortsluitreaktansie die enigste maatstaf om te bepaal of die transformatorwikkeling vervorm is. Die lae-spanning kortsluiting impedansie toets is die mees direkte metode om te kontroleer of die wikkeling vervorm is nadat die transformator geraak is deur kortsluit stroom tydens werking, of nadat die transformator geraak is deur meganiese krag tydens vervoer en installasie. Dit is belangrik om te beoordeel of die transformator in werking gestel kan word. Dit is ook een van die basis vir die beoordeling of die transformator demontage-inspeksie vereis.

Produk Verkooppunt Inleiding

1. Meting van drie-fase kortsluiting impedansie:
Vertoon drie-fase spanning, drie-fase stroom, drie-fase krag; bereken outomaties die persentasie impedansiespanning omgeskakel na nominale temperatuur en nominale stroom van die transformator, en die persentasie fout met die impedansie van die naamplaat.
2. Meting van enkelfase kortsluitimpedansie:
Meet die kortsluitimpedansie van 'n enkelfase-transformator.
3. Meting van nul-volgorde impedansie:
Die meting van nulvolgorde-impedansie is geskik vir transformators met neutrale punt in sterverbinding aan die hoogspanningskant.
4. Dit kan direk gemeet word binne die toelaatbare meetbereik van die instrument, en eksterne spanning- en stroomtransformators kan buite die meetbereik gekoppel word. Die instrument kan die transformasieverhouding van die eksterne spanning- en stroomtransformators stel, en die toegepaste spanning en stroomwaardes direk vertoon.
5. Die instrument neem grootskerm kleur hoë-resolusie touch LCD, Chinese spyskaart, Chinese aanwysings, en maklike werking.
6. Die instrument kom met 'n drukker, wat data kan druk en vertoon.
7. Ingeboude geheue sonder krag, kan 200 stelle meetdata stoor.
8. Die instrument is toegerus met 'n U-skyf-koppelvlak vir toegang tot toetsdata.
9. Permanente kalender, klokfunksie, tydkalibrasie kan uitgevoer word.
10. Die instrument het 'n wye meetreeks, hoë presisie en goeie stabiliteit; klein grootte en ligte gewig is gerieflik vir meting.

Understanding and Choosing a Line Impedance Tester for Optimal Network Performance

In the realm of telecommunications and electrical engineering, maintaining the integrity of transmission lines is paramount. A line impedance tester is a crucial instrument for ensuring optimal signal transmission and preventing costly network disruptions. This article delves into the world of line impedance testing, exploring its importance, applications, types of testers, and what to look for when making a purchase. Ensuring accurate impedance measurements is essential for efficient and reliable network performance. Choosing the right tester can significantly impact troubleshooting speed and the overall quality of your infrastructure. A line impedance tester, also known as a cable impedance analyzer, is a device used to measure the characteristic impedance of coaxial cables, twisted pair cables, and other transmission lines. Impedance, measured in ohms, represents the opposition to the flow of alternating current. Maintaining the correct impedance (typically 50 or 75 ohms) is vital for minimizing signal reflections, ensuring efficient power transfer, and preventing signal degradation. Mismatched impedance can lead to signal loss, ghosting, and reduced network performance. Regular testing helps identify faults and maintain network integrity.
