南澳电气NAZT全自动变压器直流电阻快速测试仪注意事项

为了您和设备的安全，请操作人员仔细阅读以下内容:

① 在测量完感性负载时不能直接拆掉测试线，以免由于电感放电危及测试人员和设备的安全。本变压器直流电阻快速测试仪的输出端设有放电电路。关闭输出时，电感会通过仪器泄放能量。一定要在放电指示完毕后才能拆掉测试线。

② 对于无载调压变压器，不允许测量过程中切换分接开关。

③ 测量过程中如果电源突然断电，本变压器直流电阻快速测试仪会自动开始放电，请不要立刻拆卸接线，至少等待30秒钟后才可拆卸接线。

④ 测量时，其他未测试的绕组请勿短路接地，否则会导致变压器充磁过程变慢，数据稳定时间延长。

⑤ 开机前请检查电源电压:交流220V±10% 50Hz。

⑥ 试验时请确认被测设备已断电，并与其它带电设备断开。

⑦ 试验时机壳必须可靠接地。

⑧ 试验时不允许不相干的物品堆放在设备面板上和周围。

⑨ 更换保险管和配件时，请使用与本仪器相同的型号。

⑩ 本变压器直流电阻快速测试仪注意防潮、防油污。

 

Product introduction

Transformer DC Resistance Tester also named Low Resistance Ohmmeter, It is a necessary testing project for transformer transition, overhauling and changing tap switch, it is also an important detecting project after fault. Transformer DC Resistance Tester is a quick test equipment for testing transformers, generators, motors, lines and other DC resistance.

Transformer DC Resistance Tester is integrated high-precision power supply and DC resistance test in a whole as a new instrument, which not only maintain the original advantage but also greatly reduces the size and weight of the instrument and expands the measurement range. The instrument adopts the high-performance single-chip microcomputer control, simple operation, easy to carry, fast testing speed, high precision, good retest, strong anti-interference capability, automatically complete the judgment of steady flow, data acquisition and processing and display resistance, can accurately complete the measurement of transformer dc resistance, This instrument is the best testing equipment for power plant, power supply enterprises, medium and large-sized power transformer manufacturing industries and enterprises.

According to different level of current, Nanao Electric Wuhan Co., LTD has developed six types of Transformer DC Resistance Tester, they are NAZT-, NAZT-10A, NAZT-20A, NAZT-40A, NAZT-50A, NAZT -100A, etc.

Also called name

DC Resistance Rapid Tester, Transformer DC Resistance Tester, Transformer DC Resistance Rapid Tester, Transformer Winding DC Resistance Tester, Inductive Load DC Resistance Rapid Tester, Inductive Load DC Resistance Tester, Sensual loaded DC resistance tester.

The Characteristics of the products

1. Large output current, wide measuring range, small size, light weight, simple operation;

2. Fast test speed, high measurement accuracy, good retest capacity, strong anti-interference capability;

3. With perfect function of protection circuit and discharge alarm, reduce the wrong operation, good reliability;

4. Adopting high speed micro-controller to automatically complete the judgment of steady flow, data acquisition and processing and display resistance;

5. Using 192 * 64 large-screen LCD display, outdoor display is clearly visible;

6. Built-in high-capacity a non-volatile memory, can store 500 sets of measurement data;

7. Built-in high-precision real-time clock function, date and time can be calibrated.

8. With high speed micro thermal printer: can print measurement and historical data.

 

Attention should take for your safety, please read the following:

① After measured the inductive loaded, the testing line can not be removed directly, avoid the inductor discharge that may endanger the testers and equipment safety. The output of DC resistance quick tester set a discharge circuit. once turn off the output, the inductor will discharge energy through the instrument. Be sure to remove the testing line after the discharge instructions is finished.

② For no-load tap changer, is not allowed to switch the tap during the measuring process.

③If power is off suddenly during the measuring process., the DC resistance quick tester will automatically start to discharge, do not remove wiring immediately, need to wait for least 30 seconds ,

④ In the process of measuring, other untested windings should not grounded short circuit, otherwise it will cause the transformer magnetizing process slowed down, the data stabilized longer.

⑤ Please checking the power supply voltage before starting: AC 220V ± 10% 50Hz.

⑥ Make sure the device is power off before testing, and disconnected with other energized equipment.

⑦ The casing must be grounded firmly.

⑧ Not allow irrelevant items stacked on and around the device panel.

⑨ When replace the fuse and accessories, please use this instrument with the same model.

⑩ The DC resistance tester quick test pay attention to the moisture and grease.
