检测电弧故障保护电器中电缆试品的制作

Introduction on the Sample( s) Cable Production in Testing Arc Fault Detection Device

电缆试品试验是检验电弧故障保护电器(AFDD)性能的重要手段之一,比电弧发生器试验更客观、更接近实际。选用三种型号的电缆、两种切口方式、一种电缆铰接方式,经过大量试验测得了各种数据及其电弧波形。经分析,不同的电弧波形与电缆试品的选材、电缆试品的制作有直接关系。

The sample cable test is an important means to test the performance of arc fault detection device （AFDD） ,and it is more objective and closer to the reality than the arc generator test. Three types of cable, two kinds of cutting method and a cable hinged way were selected. The various data and the arc shape were measured by a large number experiment. By analysises, the different arc waveforms are directly related to the material selection and the production of cable products.
