Abstract

The invention relates to a power transmission line icing intelligent on-line monitoring system which comprises an icing monitoring unit, a communication network and a server. The icing monitoring unit is connected with the server through the communication network and collects state information of a power transmission line, icing thickness information is figured out through an icing thickness mathematical model, the state information and the icing thickness information are transmitted to the server through the communication network in real time, and icing thickness changing trend information of the power transmission line is calculated through the server according to the state information and the icing thickness information. If the icing thickness exceeds a setting threshold value, an alarm is timely given, so real-time monitoring for the power transmission line is achieved. Compared with the prior art, the power transmission line icing intelligent on-line monitoring system has the advantages of being high in integration and reliability and low in power consumption.

Description

technical field

[0001] The invention relates to a power transmission line monitoring system, in particular to an intelligent on-line monitoring system for icing of a power transmission line. Background technique

[0002] The existing on-line monitoring products for icing on transmission lines all have the following defects:

[0003] (1) The stability of the system is not good, and a failure occurs after several days of online operation;

[0004] (2) Due to the high power consumption of the system, the solar panels cannot charge the battery under the weather conditions such as cloudy, rainy, snowy and cold for several consecutive days, so the system cannot work normally due to power shortage. The critical moment of the collapse of the tower;

[0005] (3) The system has poor low-temperature characteristics and cannot operate normally for a long time in complex environments such as outdoor severe cold, rain and snow;

[0006] (4) Even if it can withstand severe cold, rainy a...
