On-line monitoring system for strain clamp temperature of transmission line
During the long-term operation of high-voltage transmission lines, problems such as surface oxidation and corrosion, loosening of imprisoned bolts, and poor contact contact often occur in fittings and clamps, which cause overheating of the equipment, which leads to fires and large-scale power outages, resulting in major economic losses. Loss and serious social impact. Therefore, real-time temperature monitoring of strain clamps on transmission lines is very necessary. However, due to the high voltage during the operation of the transmission line and the distance from the ground, it is difficult to conduct manual inspections or wire temperature measurement. For a long time, the power operation department lacked effective means for real-time temperature monitoring of high-voltage transmission lines. An online monitoring system for the temperature of strain clamps of transmission lines based on wireless sensor network technology came into being.
The on-line monitoring system for strain clamp temperature of transmission lines uses high-precision temperature sensors attached to the wires to collect the temperature of the wires, and sends the collected information to the monitoring center in time through the GSM/CDMA/GPRS or 3G network, so as to realize the detection of the wires. Real-time monitoring of temperature.
The system uses high-energy batteries and solar panels + storage batteries for power supply, and according to customer needs, adopts the method of induction to obtain electricity, which is easy to install. After being put into operation, the operation department can timely grasp the heating condition and development trend of the wire, and scientifically arrange the online capacity increase of the transmission line based on this parameter, improve economic efficiency, and improve the safe operation of the line and the level of information management.
Transmission line conduction (ground) line icing galloping, wind deviation, deicing jump, sag increase (such as when the ground line is icing), etc., may cause the phase-to-phase and relative-to-ground distance to change, resulting in line fault tripping, and tower structure Damage, even serious damage such as falling tower.
The intelligent spacer bar realizes real-time online monitoring of wind deviation, galloping, distance to ground, and working temperature of high-voltage transmission lines, and provides early warning to avoid the above-mentioned accidents on transmission lines, and can reduce maintenance and maintenance costs.
Intelligent spacers use the design concept of mechatronics to integrate miniaturized, low-power motion sensing, laser ranging, temperature monitoring and other sensors, sensing energy modules and wireless communication modules into traditional spacer fittings, and use line induction to acquire energy.
