Embodiment 1
[0029] Such as figure 1 As shown, a detection system for the internal defects of the basin insulator of gas-insulated combined electrical appliances, including a miniature antenna arranged in the basin-type insulator of gas-insulated combined electrical appliances, a signal protection circuit, parameter detection equipment and a detection and analysis module installed a computer; one end of the parameter detection equipment is connected to the micro-antenna through the signal protection circuit, and the other end is connected to a computer equipped with a detection and analysis module.
[0030] The parameter detection device is a vector network analyzer.
[0031] Such as figure 2 As shown, the micro-antenna is set inside the single-phase single-box pot insulator, and the micro-antenna is a logarithmic curved surface helical antenna, such as image 3 shown.
[0032] Such as Figure 4 As shown, the signal protection circuit includes a signal isolation circuit 4N25, a transi...
Embodiment 2
[0051] The difference between this embodiment and Embodiment 1 is that the micro-antenna is arranged inside the three-phase common box-type pot insulator, and the micro-antenna is composed of three curved surface loop antennas, as Figure 5 shown.
Embodiment 3
[0053] A detection method for the internal defect detection system of the basin-type insulator of the gas-insulated combined electrical appliance, comprising the following specific steps:
[0054] Step 1: Calculation of impedance correlation coefficient: the impedance correlation coefficient r xy The calculation method is:
[0055] r x y = Σ i = 1 n ( x i - x ‾ ) ( y i - y ‾ ...
