Automatic insulator salt density online detection device

Abstract

The invention relates to an automatic insulator salt density online detection device which comprises a sampling insulator, a cleaning arm mechanism arranged inside a machine box, an opening and closing type sealing cover and a salt density measuring instrument. The sampling insulator is suspended on a power device, due to the fact that the working condition of the sampling insulator is the same as that of a running insulator, the filthy state of the sampling insulator can be represented by the sampling insulator, and when the device is not used, the sampling insulator can be suspended outside the machine box of the salt density online detection device, and the cleaning arm mechanism is sealed in the opening and closing type sealing cover. When measuring is required, the sampling insulator ascends to enter the machine box, the cleaning arm mechanism is moved out of the opening and closing type sealing cover, automatic cleaning working is carried out on the sampling insulator, cleaning soiling solutions are collected, and the salt density measuring instrument can measure the salt density numerical value. The automatic insulator salt density online detection device is convenient to use, high in automation degree and suitable for all-weather automatic measuring on the salt density of the insulator, accurately reflects the dirt deposition state of the insulator, and provides data support for the safety running of a power grid.

Description

technical field [0001] The invention relates to an automatic insulator salt density on-line detection device, which belongs to the field of electric equipment. technical background [0002] So far, a lot of research work on insulator pollution flashover has been carried out at home and abroad. my country has also comprehensively carried out the drawing of the distribution map of the grid pollution area, formulated a series of anti-pollution flashover technology specifications, and completed in the 1990s Three different levels of power transmission and transformation equipment, especially the adjustment of creepage distance of transmission lines. [0003] Nevertheless, since the reform and opening up, my country's economy has developed rapidly, but due to the lack of attention to environmental protection, industrial and agricultural pollution is very serious, resulting in a sharp deterioration of the environment, pollution flashover accidents have not completely disappeared f...

Problems solved by technology

When this method measures salt density, it is necessary to remove the insulator from the power equipment, and use a high-voltage plasma discharge gun to eliminate the hydrophobicity at the measurement point. The process is cumbersome and complicated.

In addition, the accuracy of the equivalent salt density obtained by sampling measurement is not high enough
