Gap noise generator for testing the characteristics of EMI(electromagnetic interference) from transmission lines

摘要

Radio disturbance characteristics of the transmission lines experimental artificial noise generator according to the present invention is mounted to the transmission lines in the vertical downward direction, and the inside of the support provided with additional electrodes for the discharge gap; Disk member of the assembly and separating the lower end of the support can be coupled, generates the electrostatic capacitance with the ground; And it coupled to the upper end of the support, and is configured to include a fixing member for fixing the structure comprising the support and the disk member on a power transmission line.; According to the present design as, if the disk member to generate a support and the electrostatic capacitance which generates a gap discharge assembly and separation there is an available structure, sufficient mutual capacitance is secured to the artificial noise generator line even in a high-voltage power lines easy and various properties of the radiation noise can be accurately irradiated. In addition, there are cases, depending on the line conditions have to make any changes to the capacitance magnitude of the noise generator, the number of copies that can be freely it is possible to replace the disc also reduce overall test time and cost effective.
