便携式电弧光保护测试仪的设计及应用

电弧光保护装置已在变电站得到应用和验证,但目前对已施工完毕的电弧光保护装置的功能和性能缺乏测试设备进行定量检验。为了检测已安装的电弧光保护装置的性能,通过相关研究,设计了便携式电弧光保护测试仪。该设备主要包括主控模块、逆变模块、光源发生器、开关量检测模块、上位机软件等。测试仪可以实现输出定量的弧光强度和电流幅值,并对保护装置动作时间进行精确计时。通过各方面功能测试,其测试过程和结果显示,便携式电弧光保护测试仪满足相关标准对弧光保护装置主要技术性能的检定要求。

Development and application of a portable arc protection tester

An arc protection device has been applied and verified in a substation. The in-field inspection and verification of the arc protection device lack test equipment. In order to test the performance of the arc protection device, a portable electric arc light protection tester is designed. It mainly includes the main control unit, inverter module, light source generator, switch quantity detection module, management software and so on. These can realize the quantitative linkage output of arc intensity and current amplitude, and measure the protection operation time accurately. The test process and result of the function test show that the portable arc light protection tester can meet the verification requirements of relevant standards for the main technical performance of an arc light protection device.
