Abstract

The invention discloses a method and a system for detecting the performance of an oscillatory wave partial discharge measuring instrument for cable of 35kV and below. The method comprises the steps of: setting experiment parameters and selecting experiment circuit according to a control instruction sent by the master control unit; detecting the performance corresponding to the oscillatory wave partial discharge measuring instrument according to the set experiment parameters and the selected experiment circuit; the measuring loop obtaining a response signal of the performance detection corresponding to the oscillatory wave partial discharge measuring instrument and sending the response signal to the master control unit; and the master control unit analyzing and processing the response signal to obtain the performance detection data corresponding to the oscillatory wave partial discharge measuring instrument. According to the invention, the method and the system can be used for network entry detection, pattern test and arrival detection of oscillatory wave partial discharge measuring instrument; the performance detection work of the oscillatory wave partial discharge measuring instrument can be regulated and automatic and standardized detection of key items can be completed under computer control, thereby reducing the influence of uncertain factors such as personnel, equipment and the like in the detection process and improving the detection efficiency and accuracy.

Description

technical field [0001] The invention relates to the technical field of power transmission and transformation equipment, and more specifically, to a method and system for detecting the performance of a partial discharge measuring instrument for 35kV and below cable oscillation waves. Background technique [0002] In recent years, the application of the oscillatory wave partial discharge measuring instrument in the partial discharge measurement of cables with a voltage level of 35kV and below has been deepened, exposing some problems that need to be solved urgently. [0003] (1) Lack of uniform standardization requirements for instrument performance [0004] At present, due to the lack of effective performance testing methods for oscillatory wave partial discharge measuring instruments sold in the domestic and foreign markets, a unified performance testing system has not been established. The performance of the instruments provided by various manufacturers varies, and some pro...
