產(chǎn)品簡(jiǎn)介

用變比電橋測(cè)量變壓器的變比，操作過(guò)程繁瑣、測(cè)量范圍狹窄，已經(jīng)不適應(yīng)現(xiàn)代測(cè)量快節(jié)奏、高效率的要求。為此，南澳電氣（武漢）有限公司采用現(xiàn)代電子技術(shù)，研制出了新一代全自動(dòng)變比組別測(cè)試儀。它體積小，重量輕，精度高，穩(wěn)定性好。它采用了大屏幕中英文液晶屏顯示、內(nèi)置中英文菜單式操作，完成一組變壓器的測(cè)試只需11秒。NABZC全自動(dòng)變比組別測(cè)試儀是電力工業(yè)部門(mén)的理想測(cè)試儀器。

注意事項(xiàng)

1. 保險(xiǎn)1為2A,保險(xiǎn)2為0.5A。如果測(cè)試線短路,高低壓接反,會(huì)熔斷保險(xiǎn)。保險(xiǎn)熔斷后，如果進(jìn)行測(cè)量，在顯示“ 正在測(cè)量，請(qǐng)等待！ ”后停住。請(qǐng)關(guān)機(jī)，更換相同容量的保險(xiǎn)，重測(cè)。

2.連線要保持接觸良好。儀器應(yīng)良好接地！

3.儀器的工作場(chǎng)所應(yīng)遠(yuǎn)離強(qiáng)電場(chǎng)、強(qiáng)磁場(chǎng)、高頻設(shè)備。供電電源干擾越小越好，宜選用照明線,如果電源干擾還是較大，可以由交流凈化電源給儀器供電。交流凈化電源的容量大于200VA即可。

4.儀器工作時(shí)，如果出現(xiàn)液晶屏顯示紊亂，按所有按鍵均無(wú)響應(yīng)，或者測(cè)量值與實(shí)際值相差很遠(yuǎn)，請(qǐng)按復(fù)位鍵,或者關(guān)掉電源,再重新操作。

5.顯示器沒(méi)有字符顯示,或顏色很淡,請(qǐng)調(diào)節(jié)亮度電位器至合適位置。

亮度電位器是多圈電位器 ，有10圈！

6.儀器應(yīng)存放在干燥通風(fēng)處，如果長(zhǎng)期不用或環(huán)境潮濕，使用前應(yīng)加長(zhǎng)預(yù)熱時(shí)間，去除潮氣。

7.通訊口調(diào)試時(shí)使用。

Product introduction

When using this radio bridge to measure the transformer ratio, the operation procedure is complex, the measuring measure range is narrow, which is no longer meet modern fast-paced, high-efficiency requirements. Therefore, NABZC electrical uses the modern electronic technology, developed a new generation of automatic variable ratio group tester. It is small, light, high accuracy and with good stability. It uses a large-screen character display, menu operation, friendly interface. The variable group can measure at once. NABZC Automatic variable ratio group tester is ideal product for electrical industry department.

Also called name

Transformer ratio group tester, transformer ratio tester, transformer ratio automatic tester, automatic transformer ratio tester, transformer ratio group testing device, transformer ratio testing device, transformer ratio automatic testing device.

Attentions should take

1.Insurance 1 is 2A, Insurance 2 is 0.5A. If the testing line is short-circuit , the high and low voltage will be reversed, will burn the fuse. Once fused, it will be displayed " measuring , wait ! " and then stop to operate and cut off the power.Please replace the same capacity insurance, then retesting .

2.Maintain the connections is fine. The instrument should be well grounded !

3.Ensure the workplace keep away from strong electric field , magnetic field and high-frequency devices. Power supply interference should be the smaller the better, and use light line. If the power supply interference is still large, it better to use the AC purified power,.the purified AC power supply capacity just larger than 200VA will do.

4.During the operating, if there is disorder on LCD screen, and without any response after press all the button, or the measured value is much very far away from the actual value, please press the reset button, or turn off the power, then restart the operate .

5.If the displays without character display ,or the color is weak, please adjust the brightness potentiometer to the appropriate location . Brightness potentiometer is a multi-turn potentiometer with 10 laps !

6.The instrument should be stored in dry and ventilated place , if unused for a  long-term, or stored in a humid environment, it need to extend the warm-up time before using , to remove  the moisture.

7.Communication port used for debugging .
