CN208752143U 一种基于特高压换流站直流场微电感综合测试仪 失效 - 权利终止

一种基于特高压换流站直流场微电感综合测试仪
摘要：
本实用新型公开了一种基于特高压换流站直流场微电感综合测试仪，包括处理器、直流电压采样、直流电流采样、AD转换器、12C存储器，U盘处理、触控液晶、热敏打印机和R型变压器，所述直流电压采样、直流电流采样、AD转换器、I2C存储器，U盘处理、触控液晶和热敏打印机均连接于处理器，R型变压器连接有RCL测试电源和交流源档位，RCL测试电源与交流源档位连接于处理器，RCL测试电源还连接有恒流源及档位和四端法测量端子。本基于特高压换流站直流场微电感综合测试仪结构巧妙，将电容、电感和直阻测试整合到一起，达到一机多用，更好更方便适应现场测试需要；而且一次接线完成电感+直阻的测试，提高现场工作人员的工作效率。(ESM)同样的发明创造已同日申请发明专利
摘要（英）：

The utility model discloses a based on little inductance comprehensive tester of extra -high voltage current conversion station direct current field, including treater, direct current voltage sample,direct current sampling, AD converter, 12C memory, USB flash disk processing, touch -control liquid crystal, thermal printer and R type transformer, direct current voltage sample, direct current sampling, AD converter, I2C memory, USB flash disk processing, touch -control liquid crystal and thermal printer are all connected in the treater, and R type transformer is connected with RCL testing powersupply and AC source gear, and the RCL testing power supply is connected in the treater with the AC source gear, and the RCL testing power supply still is connected with constant current source and gear and four hold -carrying measurement terminal. This based on little inductance comprehensive tester of extra -high voltage current conversion station direct current field structure is ingenious, with electric capacity, inductance with directly hinder the test and integrate together, reaches a tractor serves several purposes, the existing field test needs of better more convenient adaptation, and once the test of inductance + directly hinder is accomplished in the wiring, improves site work personnel's work efficiency.
