摘要
近年来ADSS光缆已成为110 kV及以下电力通信的首选光通信传输介质。ADSS光缆具有绝缘良好,抗拉强度高,可与电力线同杆塔架设等优点,但存在着易电腐蚀等缺陷。对ADSS光缆产生电腐蚀的原因和控制方法作了详细的阐述,并通过一个ADSS光缆电腐蚀案例的分析,讨论了ADSS光缆产生电腐蚀的必要条件和预防方法,证明了ADSS光缆的电腐蚀在110 kV及以下的电压等级上是可以控制的,ADSS光缆是可以安全运行的。
In recent years ADSS cable has become the preferred communications medium for power communications of 110 kV and below lines. ADSS cable features good insulation, high tensile strength, being able to be installed on the same poles for power lines, however it exists the problem of being subject to electric corrosion. So the causes and control methods for ADSS cable occurring electric corrosion are described in detail, and through a case analysis about an ADSS cable being electrically corroded, the necessary conditions and prevention methods for ADSS cable to occur electric corrosion are discussed. It is proved that the electric corrosion in the lines of 110 kV and below levels is controllable, and ADSS cable can operate safely.
