Online intelligent monitoring device of insulators, and monitoring method thereof

Abstract

The invention discloses an online intelligent monitoring device of insulators. The device comprises a leakage current collecting device, wherein a coaxial shielding wire is installed on the leakage current collecting device, and the leakage current collecting device is connected to a precision resistance sampling device through the coaxial shielding wire; the precision resistance sampling device is connected with a voltage amplification module; the voltage amplification module is connected with a filter processing module; the filter processing module is connected to a microprocessor through asignal isolator; and the microprocessor transmits data to a background monitoring platform through an NB-IoT module, and a display screen is correspondingly arranged on the background monitoring platform. The overall structure of the device is remote control monitoring, and the collected micro current data are gradually converted into stable digital display data by means of a series of operations,thereby being intuitive and accurate, reducing the influence of various factors on the information data, and ensuring extremely small errors and extremely high precision.

Description

technical field [0001] The invention relates to the field of on-line monitoring equipment for intelligent power equipment, in particular to an insulator on-line intelligent detection device and a monitoring method thereof. Background technique [0002] As a special insulation control, insulators are widely equipped in high-speed railways and power systems. In the initial stage of operation, the surface of the insulator is relatively clean and the insulation performance is good; however, as the operation time increases, atmospheric pollutants gradually deposit on the surface of the insulator, forming insulator pollution. When the pollution is damp, it is easy to cause pollution flashover. With the high-speed operation of the train, the roof insulator will be attacked by various complex environments along the line, and certain pollution will be deposited on its surface. In humid weather such as fog, dew, drizzle, etc., the water in it may exist in the form of separated water ...
