變壓器繞組的直流電阻測(cè)試是變壓器在交接、大修和改變分接開(kāi)關(guān)后,的試驗(yàn)項(xiàng)目。在通常情況下,用傳統(tǒng)的方法(電橋法和壓降法)測(cè)量變壓器繞組以及大功率電感設(shè)備的直流電阻是一項(xiàng)費(fèi)時(shí)費(fèi)工的工作。為了改變這種狀況,縮短測(cè)量時(shí)間以及減輕測(cè)試人員的工作負(fù)擔(dān),本公司開(kāi)發(fā)了直流電阻快速測(cè)試儀。它采用全新電源技術(shù),具有測(cè)量迅速、體積小巧、使用方便、測(cè)量精度高等特點(diǎn)。是測(cè)量變壓器繞組以及大功率電感設(shè)備直流電阻的理想設(shè)備。 產(chǎn)品別名:變壓器直流電阻測(cè)試儀、直流電阻快速測(cè)試儀、直流電阻測(cè)試等等。 | ||||||||||||||||||||||||||||||||||||||||||||||||||||||||||

AL104DC Resistance Fast Tester
Implementation of standards.
GB6587-86、GB6593-86
DC resistance of transformer is a key test item in delivery test, installation, and acceptance trial of finished and semi-finished products in the manufacturing of transformer, and in preventive test of power department.
Catering to the needs of fast measuring of transformer DC resistance, the equipment is developed to have brand new power source technology with small size, light weight, high measuring accuracy and simple operation, capable of auto-completing test and data saving and functions of self discharge and discharge indication. It can save 999 groups of data, which are uploaded to upper computer through RS232 port.
Interface of equipment is designed in high dot matrix graphic LCD module, with friendly man-machine interaction and clear and sufficient indication of test procedure and working condition; adoption of intelligent and automatic design increases test efficiency and alleviates working intensity of operating staff.
The equipment has an application in measurement and analysis of inductance low resistance value of power transformers and winding of mutual inductor.
