產品簡介

NAYZC全自動變壓器有載開關測試儀是用于測量和分析電力系統中電力變壓器及特種變壓器有載分接開關電氣性能指標的綜合測量儀器。它采用計算機控制，通過特殊設計的測量電路，可實現對有載分接開關的過渡時間、過渡波形、過渡電阻、三相同期性、等參數的測量。用戶可根據需要和現場條件，直接由分接開關引線進行測量，也可由變壓器三相套管及中性點直接接線測量。

變壓器有載開關測試儀具有對所測數據進行分析、存貯、打印等功能。解決了目前電力變壓器有載分接開關測量方法落后，沒有專用測試手段的問題。可在電力設備預防性試驗及變壓器大修中及時診斷出有載分接開關的潛在故障，對提高電力系統運行的可靠性具有重要意義。

產品別名

有載分接開關測試儀,變壓器有載分接開關測試儀,變壓器有載開關測試儀

產品特性

NAYZC?變壓器有載開關測試儀

產品特性

1、光線示波器功能

儀器分三通道可同時記錄A、B、C三相，儀器可自動捕捉和顯示過渡過程中過渡電阻及時間跳變的過程。不受天氣影響，功能遠比光線示波器優越。

2、較強的綜合能力

在一臺儀器內可實現對有載分接開關各種參數的測量。如開關選擇、切換全過程中有無開斷點、過渡波形、過渡時間、過渡電阻、三相同期性等。配合各功能按鍵，可分析波形中的各時間段的時間及阻值。

3、打印輸出

儀器配有一臺面板式前換紙型高速打印機。

4、具有良好的抗干擾性能

全鋁合金機箱和儀器內配有電源噪音濾波器及抗干擾電路，可在電源質量較差, 且有強電磁場干擾的現場進行可靠測量。

5、數據保持，數據通訊

使用者所測量的數據及波形，可保存在儀器內。所存貯的波形多達128組，不會因斷電而丟失，現場存貯的試驗結果可通過專用數據線經串口傳送到計算機里保存。（南澳電氣（武漢）有限公司送專用軟件）

Product introduction

NAYZC?series ?transformer load switch tester is integrated testing device, used for measuring and analyzing thepowertransformers andspecial transformers with load switch electrical performance in the power system. It adopts microcomputer control, through the precision designed measuring circuit, that canrealizeon-load switchtransition time, transition waveform , transition resistance , three-phase simultaneous and other parameters measured accurately. Users may need and site conditions , leadsdirectlyfrom the tap tomeasure , but also by the three-phase transformer casing and wiring direct measurement of the neutral point . Based on user need and on-site condition, can measure directlyvia a tapswitch lead, andalso can measure though transformer three-phase drive?pipe and neutral point directly.

Transformer load switch tester, the measured data can be analyzed, stored and printed. Solve the problems of current powertransformeron-load tapbackward measuring methods, and no dedicated testing methods. In the process of electrical equipment preventive testing and transformers overhauling, it can diagnose the loadedtap switchpotentialtrouble timely, it’s important to improve power system reliability.

Also called name

On-load tap tester, transformer load top switch tester, transformer load tap tester

The Characteristics of the products

NAYZC?Transformer Load Switch Tester

Products Characteristics

1.Light oscilloscope function

Instrument is divided into three channels,which can be recorded simultaneously A, B, C phase ,the instrumentcanautomatically?capture and displaythe process of transition process transition resistance and time transition.Weather-proof,the functions is superior than light oscilloscope.

2.Strong integrate ability

Can realize on -load tap- measurement of various parameters just by a single instrument. Such as switch selection,switch wholeprocesswithout openingthe break?point,transition waveform, transition time,transition resistance,three-phase simultaneous and so on. Match with the function keys,you can analyze the waveform ofeachtime period andresistance.

3.Printout

NAYZC?transformer load tap tester is equipped with a front plate counter?top for high-speed printer paper.

4.With good anti-jamming performance.

All-aluminum chassis and instrument are equipped with power supply noise filter and anti-jamming circuit,can be tested in theweakpower,strongelectromagnetic interference field.

5.Data saved, data communicated.

The measured data and waveform can be stored in the instrument.The stored wave?forms can up to 128 groups,will not be lost duetopoweroff,on-site testing results can be stored via a dedicated data line to the computer by serial transmission of preservation.( Nanao?Electric?Wuhan Company?send specialsoftware)
