摘要
矿区6 kV供电架空线网络,经常出现导线断线事故,引起谐振过电压,导致供电设施损坏,严重影响了供电系统的安全运行。针对断线谐振过电压的产生机理,结合实际,提出了一系列防止断线谐振过电压事故的措施,能有效减少断线谐振过电压的产生,避免因此造成的电网危害,提高供电系统的可靠性。
The 6 kV overhead power line network in mining area, frequently appears wire break aecident, causes the resonant overvoltage, leads to the power supply facility damage, seriously affect the safe operation of power supply system. In connection with the mechanism of wire break resonant overvoltage, combines the actual, puts forward a series of measures of preventing the wire break resonant overvoltage aecident, can reduce effectively the wire break resonance overvoltage, avoids the electrical network harm, improves reliability of power supply system.
