Mine power supply line is a line system that provides power transmission for various operations such as mine production, transportation, ventilation, drainage, etc. It connects the substation with various mining sites, processing sites and many ancillary facilities, and is the key to ensure the normal operation of the mine, for example, open-pit mines use overhead lines as the main distribution to the mobile substation to supply power to the electric shovels, drilling rigs and other equipments. The successful delivery of power to the mine's supply lines has always signaled a reliable source of energy for the high quality and sustainable development of the local mines.
However, due to the complexity and specificity of the mining environment, power supply lines face many hidden dangers, which may not only affect the normal production of the mine, but also pose serious threats to personnel safety and equipment. Specifically, the hidden dangers faced by power supply lines in mining areas mainly include the following aspects:
First, external damage. Due to the many large-scale machinery and equipment in the mining area, and transportation vehicles frequently to and from the power supply lines are very vulnerable to vehicle collision, mechanical scraping and other external damage. At the same time, some criminals may also be on the power supply line theft or destruction, to the mine power supply safety poses a great threat.
Second, the impact of natural disasters. Mining power supply lines are susceptible to landslides, mudslides and other natural disasters, triggering landslides and collapses, power supply line breaks, tower collapses and other serious consequences, resulting in large-scale power outages. In addition, the mine is located in the open, high terrain area, is very easy to become the target of lightning strikes, triggering short-circuit faults, according to statistics, in the high incidence of lightning in the mine area, the annual line failure due to lightning strikes accounted for about 30%.
Third, equipment aging and failure. Due to the influence of the environment of power supply lines in mining areas, the aging speed of equipment is faster. Problems such as aging insulators, wear and tear of wires, rusting of gold tools and so on are endless, and these may lead to frequent power supply line failures.
To ensure the safe operation of mining power supply lines, Shenzhen Dingxin Wisdom Technology pushed out Mine power supply line integrated monitoring system, including slope monitoring, personnel positioning, mine line AI image monitoring device, mine line AI video monitoring device, mine line image video monitoring device [dual-optical dome], mine line Distributed fault location monitoring device, mine cable fault and hidden danger monitoring system, distribution network traveling wave type fault warning and positioning device, mine line iso icing online monitoring device, microwave icing monitoring device, micrometeorological online monitoring device, tower tilt online monitoring device, Beidou geologic disaster online monitoring device, conductor tension-resistant clamp temperature measurement device, conductor dance online monitoring device, insulator dirt online monitoring device, intelligent integrated management platform and so on. Device, intelligent integrated management platform, etc., can be real-time monitoring of the operating status of the power lines and wireless transmission back to the monitoring center for analysis, such as the above-mentioned wire temperature, insulator filth, tower tilt and other key parameters, lightning/non-lightning strike fault diagnosis + positioning, once abnormal conditions are found, the monitoring equipment will be immediately alerted through the web and text messages, to remind the staff to timely processing.
As an important guarantee for power supply in mining area, the safe operation of mining power lines is crucial for the production and development of mining area. The application of online monitoring equipment provides a strong guarantee for the safe operation of power supply lines in mining areas. Through real-time monitoring and data analysis, we can find and deal with all kinds of hidden dangers in the power supply line in a timely manner, to ensure the stability and reliability of the power supply in the mining area, and to contribute to the sustainable development of the mining area.
