Abstract

A device for automatically comparing power grid pollution area maps comprises a paper map scanner and a graph working station. The paper map scanner is in physical connection with the graph working station through an SCSI interface or an EPP interface or a USB interface or an IEEE1394 interface. The device for automatically comparing the power grid pollution area maps is logically composed of a map digitized unit, a data interface unit, a data storage unit, an insulator creepage ratio distance analysis unit and a pollution condition change analysis unit. The invention further relates to a method utilizing the device to compare the power grid pollution area maps. The device and method are used for automatically analyzing devices needing insulator creepage ratio distance adjustments in the power grid pollution area map revision process or after power grid pollution area map revision, and conducting comparison analysis and statistics on pollution area distribution maps of historical versions. The device can adjust the creepage ration distance automatically, saves time and labor, improves condition accuracy, and is capable of knowing creepage ratio distance workload at any time in any place and visually understanding changing conditions of pollution areas.

Description

technical field [0001] The invention relates to an automatic comparison device for the distribution map of the polluted area of ​​the power grid. The invention also relates to an automatic comparison method for the distribution map of the power grid pollution area by using the device. Background technique [0002] Power grid equipment, especially power transmission equipment, is mostly directly exposed to the natural environment. After long-term operation, it is easily polluted by dust particles in the air and various compounds. Soluble in water, a layer of conductive film is formed on the surface of the insulator, which greatly reduces the insulation level of the insulator, and the strong discharge phenomenon under the action of the electric field is the phenomenon of pollution flashover. At present, the main technical means to prevent pollution flashover include cleaning and wiping insulators, adjusting the creepage ratio of insulators, etc. [0003] The grid pollution a...
