Abstract

The invention provides a conductor slag on-line monitoring system comprising a signal collecting device, a monitoring host computer, a power supply device, an information transmitting device and a monitoring center, wherein the signal collecting device is used for collecting the temperature as well as the inclination angle and the current of a conductor; the monitoring host computer is used for pretreating the collected information to acquire the distance between the lowest point of a conductor slag and the ground and packing the distance between the lowest point of the conductor slag and the ground and the collected information; the power supply device is used for supplying power, transforming voltage and starting or stopping the monitoring host computer; the information transmitting device is used for transforming the packed information to the monitoring center; and the monitoring center is used for presetting warning values, establishing an early warning mechanism, configuring the packed information to different local area networks, and forecasting the variation trend of the conductor slag and the transmission capacity of a transmission line in real time. The conductor slag on-line monitoring system has the characteristics of strong real-time performance, high safety, reliable forecasting and the like and can be widely applied to electric systems.

Description

technical field [0001] The invention relates to a monitoring technology, in particular to an online monitoring system for wire sag. Background technique [0002] As we all know, in practical applications, the current passing through the wire will increase the temperature of the wire. However, the rise in the temperature of the wire will cause the wire to oxidize at the joint or even the joint to be burned; the increase in the temperature of the wire will also cause the wire sag to increase , so that the wires are discharged due to insufficient crossing distance. In recent years, due to the increase in power load, many existing transmission lines have increased the maximum allowable temperature of the conductor from 70°C to 80°C in order to improve the transmission capacity. At this time, the line sag has become the main restrictive factor. In addition to the changes in line operating load that will cause changes in conductor sag, the meteorological conditions of the surroun...
