Abstract

The invention discloses an insulator haze and pollution flashover online monitoring system and method. The system comprises a monitoring terminal and a monitoring device. Currents of a capacitance medium and leaked currents of an insulator are obtained through measurement at first; two signals of a single chip microcomputer are adopted and undergo computing of a formula with a solidified program to obtain a flashover value representing insulator arc-over; the flashover value is compared with a given threshold value and whether two classes of flashover alarms 'caution or danger' are given or not is judged according to a comparison result; a program for monitoring a mainframe is used for displaying a real-time monitoring result and a history data curve on a man-machine interface. On one hand, the haze and the pollution degree can be known by people in a duty room, on the other hand, a GSM short message module and a wireless communication manner are adopted for saving trouble due to remote communication and laying of wires; solar energy and a storage battery are used for supplying power and a high-voltage pulse generation manner and the low-power-consumption design are adopted for ensuring that the equipment can operate in an all-weather mode.

Description

technical field [0001] The invention relates to the field of power grid operation safety, in particular to an insulator haze and pollution flashover online monitoring system and method for preventing insulator haze and pollution flashover from insufficient external insulation caused by haze and pollution factors to cause surface flashover or air ionization breakdown discharge accidents. Background technique [0002] Due to the steady and rapid development of my country's economy, on the one hand, the demand for electricity is increasing day by day, the voltage level of power system transmission lines is constantly increasing, the scale of the power grid is constantly expanding, and the number of AC and DC interconnections is increasing. On the other hand, pollution sources in various regions are constantly increasing. Pollution intensified. Pollution will be deposited on the surface of insulators exposed to polluted conditions. When encountering adverse weather such as heavy ...
