Embodiment Construction

[0028] It should be noted that, in the case of no conflict, the embodiments in the present application and the features in the embodiments can be combined with each other. The present invention will be described in detail below with reference to the accompanying drawings and examples.

[0029] figure 1 It is a flowchart of an interference suppression method for equipment partial discharge detection according to an embodiment of the present invention.

[0030] like figure 1 As shown, the method includes the following steps S12 to S16:

[0031] Step S12: Simultaneously detect ultra-high frequency signals inside and outside the device. In this embodiment, a signal sensor and a noise sensor are used to respectively detect ultra-high frequency signals from inside the device and from outside the device.

[0032] Step S14: synchronously comparing the detected intensities of the UHF signals inside and outside the device.

[0033] Step S16: Determine the part of the UHF signal ins...

Abstract

The invention discloses an interference suppression method and an interference suppression device for the local discharge detection of equipment, which are used for solving the problem that various interferences existing in the detecting environment cannot be effectively suppressed in the prior art. The method of the invention comprises the following steps: detecting ultra high frequency signals inside and outside the equipment at the same time; synchronously comparing intensity of the detected ultra high frequency signals inside and outside the equipment; and determining which part of the ultra high frequency signals belongs to outside interference of the equipment according to the intensity. The technical scheme of the invention can fulfill the aim of suppressing the outside interference of the equipment and facilitate better analysis of various discharge phenomena inside the equipment.

Description

technical field [0001] The invention relates to the field of electric power technology, in particular to an interference suppression method and device for partial discharge detection of equipment. Background technique [0002] Gas insulated switch GIS (Gas Insulated Switchgear) is an important part of power grid equipment. It has a large number and is widely used in urban power grids. GIS has a compact structure and is very sensitive to internal tiny insulation defects, which can easily lead to serious accidents of insulation breakdown. Conventional inspections cannot effectively understand the operating status of equipment; due to the fully enclosed nature of GIS, the on-site maintenance environment requires high requirements, and the workload of disassembly and assembly is large. , the power outage time is long, and the maintenance cost is expensive. The maintenance-free operation period of GIS is about 15 years, and most of the time of failure occurs when it is just put ...
