[0015] The on-line test method of the arc protection unit of the present invention is as follows: (1) First, install an arc sensor inside the switchgear, the installation position of the arc sensor can receive the arc light generated when the switchgear fails, and fix it around the arc sensor The analog light source with adjustable light intensity determines the installation position and installation method of the analog light source through the position of the arc sensor. The light emitted by the analog light source can be effectively received by the arc sensor. The analog light source is installed firmly to avoid the operation and normality of the power equipment Strong impact and vibration during use. In addition, the simulated light source of the present invention can choose high-brightness halogen lamps and other lamps with higher luminous intensity, and the luminous intensity of the light source must reach more than 8000 LUX. (2) Under the condition of normal operation of th...
