产品简介

NAYZC全自动变压器有载开关测试仪是用于测量和分析电力系统中电力变压器及特种变压器有载分接开关电气性能指标的综合测量仪器。它采用计算机控制，通过特殊设计的测量电路，可实现对有载分接开关的过渡时间、过渡波形、过渡电阻、三相同期性、等参数的测量。用户可根据需要和现场条件，直接由分接开关引线进行测量，也可由变压器三相套管及中性点直接接线测量。

变压器有载开关测试仪具有对所测数据进行分析、存贮、打印等功能。解决了目前电力变压器有载分接开关测量方法落后，没有专用测试手段的问题。可在电力设备预防性试验及变压器大修中及时诊断出有载分接开关的潜在故障，对提高电力系统运行的可靠性具有重要意义。

产品别名

产品特性

NAYZC 变压器有载开关测试仪

产品特性

1、光线示波器功能

仪器分三通道可同时记录A、B、C三相，仪器可自动捕捉和显示过渡过程中过渡电阻及时间跳变的过程。不受天气影响，功能远比光线示波器优越。

2、较强的综合能力

在一台仪器内可实现对有载分接开关各种参数的测量。如开关选择、切换全过程中有无开断点、过渡波形、过渡时间、过渡电阻、三相同期性等。配合各功能按键，可分析波形中的各时间段的时间及阻值。

3、打印输出

仪器配有一台面板式前换纸型高速打印机。

4、具有良好的抗干扰性能

全铝合金机箱和仪器内配有电源噪音滤波器及抗干扰电路，可在电源质量较差, 且有强电磁场干扰的现场进行可靠测量。

5、数据保持，数据通讯

使用者所测量的数据及波形，可保存在仪器内。所存贮的波形多达128组，不会因断电而丢失，现场存贮的试验结果可通过专用数据线经串口传送到计算机里保存。（南澳电气（武汉）有限公司送专用软件）

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)
