Abstract

The invention relates to the technical field of power transmission, and particularly discloses a power transmission line icing automatic monitoring device. The power transmission line icing automatic monitoring device comprises a sensor group and a microcomputer control box, wherein the sensor group comprises tension sensors, a temperature and humidity sensor and a wind speed sensor, the tension sensors are used for measuring the icing weight of a simulated wire, the temperature and humidity sensor is used for measuring the temperature and the humidity of an operating environment of a power transmission line, the wind speed sensor is used for measuring the wind speed of the operating environment of the power transmission line, the microcomputer control box comprises a transmitter group, an A / D converter, a central processing unit, a communication interface and a power supply, the transmitter group is connected with the sensor group and connected with the central processing unit through the A / D converter, and the communication interface is connected with the central processing unit. The power transmission line icing automatic monitoring device acquires the icing weight of the simulated wire and the temperature, the humidity and the wind speed of the operating environment of the power transmission line through the sensor group, calculates the icing thickness and icing development situations of the power transmission line through the central processing unit, and then sends relevant data to a monitoring center through the communication interface, thereby realizing automatic, effective and real-time monitoring for icing conditions of the power transmission line.

Description

technical field [0001] The invention relates to the technical field of electric power transmission, in particular to an automatic ice monitoring device for power transmission lines. Background technique [0002] In order to ensure the safe operation of transmission lines in the freezing season and prevent accidents such as line collapse due to icing, the power system needs to grasp the icing situation of transmission lines in a timely manner. [0003] At present, the monitoring methods in the prior art mainly include the following two types: one method is to set up an ice-melting monitoring post, set up a simulated wire close to the actual operation of the wire at the ice-melting monitoring post, arrange duty personnel, and the duty personnel follow the post reporting system The ice coating thickness of simulated conductors and related meteorological information are manually measured and reported by the meteorological ice observation system. There are some deficiencies in t...
