[艾尔电气 直流电阻测试仪产品简介]


变压器绕组的直流电阻测试是变压器在交接、大修和改变分接开关后,必不可少的试验项目。在通常情况下,用传统的方法(电桥法和压降法)测量变压器绕组以及大功率电感设备的直流电阻是一项费时费工的工作。为了改变这种状况,缩短测量时间以及减轻测试人员的工作负担,本公司开发了直流电阻快速测试仪。它采用全新电源技术,具有测量迅速、体积小巧、使用方便、测量精度高等特点。是测量变压器绕组以及大功率电感设备直流电阻的理想设备。

产品别名:变压器直流电阻测试仪、直流电阻快速测试仪、直流电阻测试等等。

AL104DC Resistance Fast Tester

Implementation of standards.

GB6587-86GB6593-86



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.
