Power grid high-voltage cable failure is a complex and serious technical problem, which needs to be studied and prevented from multiple angles. Only in this way can we effectively ensure the safe and stable operation of the power system and provide a strong impetus for the development of society. Next, Shenzhen Dingxin Smart Technology will lead you to understand the high-voltage cable fault and hidden danger monitoring system.
1. What is the fault of the high-voltage cable of the power grid?
We need to understand what a grid high voltage cable fault is. To put it simply, the fault of the high-voltage cable of the power grid refers to the phenomenon that the cable cannot work normally due to the quality problem of the cable itself, the damage during use or the influence of external environmental factors. These faults can be divided into several types, such as insulation faults, joint faults, mechanical damage faults, etc. Among them, insulation failure is the most common one, which is mainly caused by the aging and damage of cable insulation materials or the intrusion of moisture and gas.
2. What are the consequences of the hidden danger of high-voltage cable failure?
The occurrence of high-voltage cable failure in the power grid will directly affect the normal operation of the power system. For example, insulation failures can lead to a decrease in the insulation performance of the cable, and may even lead to a short circuit or grounding of the cable, which can trigger a power outage accident in the power system. Faulty joints may lead to poor contact of cable joints, affecting the transmission performance of the cable, and in severe cases, it may lead to cable breakage. Mechanical damage failures can cause the protective layer of the cable to break, exposing the cable directly to the external environment and increasing the risk of damage to the cable. Therefore, it is necessary to regularly inspect and repair the cable, and find and deal with the fault and hidden dangers of the cable in time.
3. What can the high-voltage cable fault and hidden danger monitoring system do?
The system consists of three parts: the monitoring end, the main station of the fault data analysis center and the user system, distributed installed at the cable joint, real-time collection of line traveling waves, after the fault occurs, through the analysis of the electric flow wave and power frequency fault current waveform of A, B and C three phases, the fault type is identified, the fault section and the fault point are accurately located, and the fault result is pushed to the setting mobile phone or through the web, client, mobile phone, providing reference for the maintenance and repair of the line.
Seeing this, we must have already realized that the fault of the high-voltage cable of the power grid is an important problem in the power system, which requires us to pay enough attention and attention to better prevent and control the faults and hidden dangers of the power system.
