Embodiment Construction

[0019] The solution of the present invention will be described in detail below in conjunction with the preferred embodiments.

[0020] figure 1 A schematic flowchart of an embodiment of the 500kV charged water flushing safety detection method of the present invention is shown in FIG. Such as figure 1 As shown, the method in this embodiment includes the steps:

[0021] Step S101: real-time monitoring of the ultraviolet image of the working waveband within the set waveband during the charged water washing process;

[0022] Step S102: Obtain the ultraviolet photon value in the ultraviolet image;

[0023] Step S103: It is judged whether the above-mentioned ultraviolet photon number is greater than or equal to a preset ultraviolet photon warning value, and if so, an alarm message is issued.

[0024] According to the solution in this embodiment, by real-time monitoring of the ultraviolet image with the working band within the set range during the charged water washing process, the ultraviole...

Abstract

The invention relates to 500 kV electrified water-washing safety detection method and device. The method comprises the following steps of: monitoring an ultraviolet image of a working waveband within the set waveband range during the electrified water washing process in real time; acquiring the value of ultraviolet photons in the ultraviolet image; and judging whether the value of ultraviolet photons is greater than or equal to the preset ultraviolet photon early-warning value, and if so, sending warning information. According to the scheme of the invention, detection is carried out by monitoring the ultraviolet image, direct contact with washed operating equipment is not needed, and the real status information of the operating equipment in the washing status can be monitored under the condition of not cutting off power and not changing the system operating status. Therefore, the safety of electrified water washing work can be effectively evaluated, and flashing accidents of electrified equipment during the electrified water washing process can be prevented.

Description

Technical field [0001] The invention relates to the technical field of power grids, in particular to a 500kV charged water flushing safety detection method and device. Background technique [0002] The large-scale pollution flashover of the external insulation of power transmission and transformation equipment is one of the main threats to the safe operation of my country's power system. Pollution flashover refers to the soluble matter of the dirt attached to the insulation surface of the electrical equipment gradually dissolving in water under humid conditions. A conductive film is formed on the insulating surface, which greatly reduces the insulation level of the insulator, resulting in a strong discharge phenomenon under the action of the electric field. In order to ensure the safety of power system operation, some anti-pollution flashover measures need to be taken to prevent the occurrence of pollution flashover accidents. At present, the more effective anti-pollution flashove...
