Abstract

The invention discloses a local discharge signal detection method and device. The method comprises the following steps: detecting a trigger signal of to-be-detected electrical equipment; when the trigger signal is detected, detecting the receiving state of a local discharge signal of the electrical equipment; adjusting the configuration parameters according to the receiving state, wherein the configuration parameters are the parameters used for detecting the local discharge signal; and detecting the local discharge signal according to the adjusted configuration parameters. The method and device disclosed by the invention solve the technical problems that the prior art cannot perform automatic adjustment of a local discharge system or detection of the local discharge signal.

Description

technical field [0001] The invention relates to the field of electric power, in particular to a method and device for detecting partial discharge signals. Background technique [0002] At present, most of the partial discharge electrification or on-line detection instruments and devices based on the UHF method are aimed at a specific high-voltage equipment (such as transformers, GIS, etc.), and multiple sensors are installed on the equipment body, and the staff need to carry multiple sets of different type of instrument, resulting in inconvenient operation. In addition, many sensors are required, the installation is complicated, the comprehensive cost of instrument purchase is high, and the maintenance workload of the detection device itself is heavy. When a set of devices is used to monitor and locate the partial discharge of the whole station equipment, the existing technology cannot realize the automatic adjustment of the positioning system. [0003] For the above probl...
