As we all know, the overhead line is the most important part of the distribution network as the carrier of urban and rural power supply, whose health status is related to the stability and safety of the distribution network and directly related to the safety of the power supply of users. Accurate cable fault indicator monitoring systems can provide real-time operation status for maintenance staff. When the line fault occurs, the automated cable fault indicator monitoring system can quickly lock the fault area according to the action signal given by the equipment to find out the fault point. The most important thing is that the digital cable fault indicator monitoring system can greatly improve work efficiency, reduce economic losses, and has important economic value and social significance.
According to incomplete statistics, the operation of China's electric power industry from January to September 2015 claimed that the whole country’s electricity consumption was 4134.4 billion kWh, a year-on-year increase of 0.8%. Among them, the domestic electricity consumption of urban and rural residents was 557.3 billion kWh, with a year-on-year growth of 4.6%, accounting for 13.5% of the total social power consumption and contributing 70.3% to the growth of the whole society. From the above data, it can be seen that the demand for power supply and automated electric wire fault indicator monitoring systems is increasing. Especially, the power consumption of urban and rural residents has been greatly developed.
However, most urban and rural distribution network systems use overhead lines for transmission. Due to the special geographical conditions, overhead lines have the characteristics of a large number, multiple branches, complex structures, and perennial exposure in the field. In addition to its own aging reasons, its safe operation is also threatened by bad weather such as thunder, lightning, typhoon, snow, and ice. In recent years, the use of digital electric wire fault indicator monitoring systems also increases with the increase of urban and rural power consumption.
It is understood that a line with only 2 km long was hit by thunderstorms and hail weather this year, resulting in power failure in some villages. Because the line has not been transformed and not installed the reliable electric wire fault indicator monitoring system, many maintenance workers went through the rain to check and find the fault point along the line, which took three or four hours for the power to return to normal.
In the past, we all rely on the maintenance staff on-site investigation when the line ground short circuit occurred, which often need to use a lot of manpower and material resources. It will take a long time to find the location of the specific fault point, which not only brings hidden dangers to the safe operation of lines and equipment but also affects the reliability of power supply. In order to quickly locate the line fault point and improve the management level of the distribution network, CHAOBO Automation Technology Co., Ltd. has developed a reliable cable fault indicator monitoring system with fault alarm, real-time collection of line operation status, and remote communication functions. The advanced cable fault indicator monitoring system is based on the structural characteristics of overhead lines, operation mode, computer network technology, communication technology, and UHV technology in China.
