The invention is applicable to the field of power detection and provides composite insulator string live detection equipment. The equipment comprises an insulating guide rail bracket arranged at the periphery of a composite insulator string, wherein detection elements are arranged on the insulating guide rail bracket; each detection element comprises an electric field probe used for detecting the electric field intensity, and also comprises a temperature sensor used for detecting the temperature and / or a humidity sensor used for detecting the humidity; the equipment also comprises a motor mechanism used for driving the detection elements to operate on the insulating guide rail bracket, a displacement detector used for detecting the displacement of each detection element, and a central processing unit, an amplifying circuit, an analog / digital conversion circuit, a storage device and a display screen; detection data comprise electric field data and temperature data and / or humidity data. Electric field data are corrected through the temperature data and / or the humidity data, the defect detection accuracy of the composite insulator string is guaranteed, and the false detection is effectively avoided.
Description
technical field [0001] The invention belongs to the field of electric power detection, and in particular relates to a composite insulator string electrification detection device. Background technique [0002] At present, the detection methods of composite insulator string defects on high-voltage transmission lines mainly include: infrared imager, which detects according to the temperature change of composite insulators on high-voltage transmission lines, and infrared imager cannot detect under the background of strong light, and the volume is large , expensive and difficult to maintain; the visual inspection method (commonly used in China) can only be observed when there are obvious defects on the outer surface of the composite insulator, but the defects inside the composite insulator are not easy to be found, and it is difficult to carry out preventive inspection and maintenance. [0003] Currently there is a method for analyzing the internal defects of composite insulator ...
