Shielding efficiency tester
Main equipment and technical requirements:
a. Power frequency voltage generator: the output requirement is 50Hz, the voltage RMS value is 600V sinusoidal voltage (waveform meets the requirements of GB311.2~ 311.6-83 “High voltage test Technology”);
b. Pressure electrode: brass; Load 2MΩ, total mass is 3kg;
c. Voltage meter: input impedance is greater than 10MΩ, measuring range is 600V, and can measure the load resistance of the pressurized electrode; d. Rubber sheet: diameter of 400mm, thickness of 5±0.5mm rubber sheet, the surface hardness of 60 kepada 65 degrees of Shore;
e. Receiving electrode plate: brass plate with 300mm diameter and terminal post, thickness 2mm;
f. Insulation board: diameter is 400mm, thickness is 5mm, the material is epoxy board;
Sampling and test environment requirements:
a. Samples can be clipped at large pieces of fabric. If it is necessary to cut on a large piece, the sample must be at least 2m away from the cloth end. The center point of the sample must be on the 45 degree diagonal of the sample fabric, and there must be no serious defects and finishing agent dipping on the sample that affect the test result Keep waiting. Sample area is determined according to test operation requirements.
b. Cut a square sample with a size of 180mm×180mm on the sample cloth at least 50mm away from the cloth edge, totaling 3 kepingan.
c. Before the test, the sample should be placed in an environment with a temperature of 23±2℃ and a relative humidity of 45~55 for more than 24 hours to adapt to the test environment. d. The test should be carried out in an environment with a temperature of 23±2℃ and relative humidity of 45~55.
