The invention relates to a power line conduction sensitivity test device based on three-phase Y-type power supply, and the device comprises a power line input port which is used for connecting a high-potential line and a neutral line; the power line output port is used for outputting a coupling signal and connecting tested equipment; the capacitor is connected between the high potential line and the neutral line; the switching circuit is used for circuit switching between the interference signal and the first phase line, the second phase line and the third phase line; the interference signal port is used for inputting an interference signal; the monitoring port is used for monitoring the coupling signal; and the fourth relay is connected in parallel between the power line input port and the power line output port. According to the invention, one-key switching among the first phase line, the second phase line and the third phase line can be realized, the test device is suitable for CS101 test and CS106 test of the three-phase Y-type power supply, shutdown and re-wiring of the test device are not needed, the test efficiency and the test safety are improved, and the test cost is saved.
Description
technical field [0001] The invention relates to the technical field of power line conduction sensitivity test, in particular to a power line conduction sensitivity test device based on three-phase Y-type power supply. Background technique [0002] The CS101 test item, that is, the power line conduction sensitivity test, is a must-test item in the GJB151 standard and is applicable to all military platform equipment. The ability to ensure that equipment performance is not degraded under pulsating voltage conditions that allow distortion of the power supply voltage waveform. At present, it is suitable for the CS101 test device with three-phase Y-type power supply. The test schematic diagram is as follows figure 1 As shown, the power supply has three high-potential lines and one neutral line. The power supply first passes through the Linear Impedance Stabilization Network (LISN), and then the three high-potential lines and one neutral line are respectively connected to the inpu...
