注意事項

為了您和設(shè)備的安全，請操作人員仔細(xì)閱讀以下內(nèi)容:

①在測量完感性負(fù)載時不能直接拆掉測試線，以免由于電感放電危及測試人員和設(shè)備的安全。本變壓器直流電阻快速測試儀的輸出端設(shè)有放電電路。關(guān)閉輸出時，電感會通過儀器泄放能量。一定要在放電指示完畢后才能拆掉測試線。

② 對于無載調(diào)壓變壓器，不允許測量過程中切換分接開關(guān)。

③ 測量過程中如果電源突然斷電，本變壓器直流電阻快速測試儀會自動開始放電，請不要立刻拆卸接線，至少等待30秒鐘后才可拆卸接線。

④ 測量時，其他未測試的繞組請勿短路接地，否則會導(dǎo)致變壓器充磁過程變慢，數(shù)據(jù)穩(wěn)定時間延長。

⑤ 開機前請檢查電源電壓:交流220V±10%50Hz。

⑥ 試驗時請確認(rèn)被測設(shè)備已斷電，并與其它帶電設(shè)備斷開。

⑦ 試驗時機殼必須可靠接地。

⑧ 試驗時不允許不相干的物品堆放在設(shè)備面板上和周圍。

⑨ 更換保險管和配件時，請使用與本儀器相同的型號。

⑩ 本變壓器直流電阻快速測試儀注意防潮、防油污。

Productintroduction

Transformer DC Resistance Tester also named Low ResistanceOhmmeter, It is a necessary testing project for transformertransition, overhauling and changing tap switch, it is also animportant detecting project after fault. Transformer DC ResistanceTester is a quick test e for testing transformers,generators, motors, lines and other DC resistance.

Transformer DC Resistance Tester is integrated high-precision powersupply and DC resistance test in a whole as a new instrument, whichnot only maintain the original advantage but also greatly reducesthe size and weight of the instrument and expands the measurementrange. The instrument adopts the high-performance single-chipmicrocomputer control, simple operation, easy to carry, fasttesting speed, high precision, good retest, stronganti-interference capability, automatically complete the judgmentof steady flow, data ac and processing and displayresistance, can accurately complete the measurement of transformerdc resistance, This instrument is the best testing e forpower plant, power supply enterprises, medium and large-sized powertransformer manufacturing industries and enterprises.

According to different level of current, Nanao Electric WuhanCo., LTD has developed six types of Transformer DC ResistanceTester, they are NAZT-5A,NAZT-10A,NAZT-20A,NAZT-40A,NAZT-50A,NAZT -100A,etc.

Alsocalled name

Attentionshould take for your safety, please read thefollowing:

① After measured the inductiveloaded, the testing line can not be removed directly, avoid theinductor discharge that may endanger the testers and esafety. The output of DCuick tester set a dischargecircuit. Once turn off the output, the inductor will dischargeenergy through the instrument. Be sure to remove the testing lineafter the discharge instructions is finished.

② For no-load tap changer, is notallowed to switch the tap during the measuringprocess.

③If power is off suddenly duringthe measuring process., the DCuick tester willautomatically 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 sloweddown, the data stabilized longer.

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

⑥ Make sure the device is poweroff before testing, and disconnected with other energizede.

⑦ The casing must be groundedfirmly.

⑧ Notallow irrelevant items stacked on and around the devicepanel.

⑨ When replace the fuse andaccessories, please use this instrument with the samemodel.

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