Embodiment 1

[0026] According to an embodiment of the present invention, an embodiment of a detection method of a partial discharge monitoring system is provided. It should be noted that the steps shown in the flowcharts of the drawings can be executed in a computer system such as a set of computer-executable instructions , and, although a logical order is shown in the flowcharts, in some cases the steps shown or described may be performed in an order different from that shown or described herein.

[0027] figure 1 is a flow chart of an optional detection method for a partial discharge monitoring system according to an embodiment of the present invention, such as figure 1 As shown, the method includes the following steps:

[0028] Step S102, receiving a first signal, wherein, after the signal generator sends the original signal to the first electric device, the first electric device processes the original signal to obtain the first signal;

[0029] Step S104, judging whether the first si...

Embodiment 2

[0051] According to another aspect of the embodiment of the present invention, a detection device for a partial discharge monitoring system is also provided, such as Image 6 As shown, the detection device includes:

[0052] The first receiving unit 61 is configured to receive the first signal, wherein, after the signal generator sends the original signal to the first electric device, the first electric device processes the original signal to obtain the first signal;

[0053] The first judging unit 62 is configured to judge whether the first signal satisfies a preset signal detection condition;

[0054] The first determining unit 63 is configured to determine that the performance of the first electric device is abnormal and issue an alarm if the first signal does not meet the preset signal detection condition.

[0055] Wherein, receiving the first signal can be completed by an oscilloscope or a background monitoring system, and the background monitoring system can be a comput...

Abstract

The invention discloses a detection method and a device for a . The method comprises the steps of receiving a first signal, wherein an original signal is sent to a first electric power instrument by a signal generator and then the original signal is processed by the first electric power instrument to obtain the first signal; judging whether the first signal meets a preset signal detection condition or not; on the condition that the first signal does not meet the preset signal detection condition, judging that the first electric power instrument is abnormal in performance and sending out an alarm. The detection method and the device solve the technical problem in the prior art that the detection efficiency on the state of power supply equipment is low.

Description

technical field [0001] The invention relates to the field of electric power, in particular to a detection method and device for a partial discharge monitoring system. Background technique [0002] In order to ensure the stable operation of the power supply system and the normal operation of the power supply equipment, power maintenance personnel need to regularly check the equipment status of the power supply equipment. UHF (UltraHigh Frequency) sensors and other UHF detection instruments such as power amplifiers, filters, and signal collectors are used. Although the partial discharge monitoring system has been widely used, there are many defects, as follows: (1) The process standards of UHF sensors are not uniform, and the performance of UHF sensors manufactured by different manufacturers is quite different; (2) The process standards of UHF detection instruments Not uniform, the performance of UHF detection instruments manufactured by different manufacturers is quite diffe...
