水文缆道防雷技术

Lightening protection technology of hydrological cableway

介绍水文缆道智能控制系统防雷电的方式方法。采用综合防雷传输器接入系统前端确保水文缆道智能控制系统后级安全;将缆道循环索松边压入主索之下;将主索接地电阻降低到5Ω以下;采用独立的太阳能电源;部分敏感设备采用物理隔离,从而对测流人员的人身安全和主要设备进行有效的保护。

An introduction was made on the lightening protection methods adopted for hydrological cableway intelli- gent control system. A lightening protection transmitter was connected to the system head to ensure the safety of sys- tem components behind. The loose side of cableway loop cahle is pressed under main cable. The earthing resistance of main cattle is reduced to below 5Ω. Independent solar power supply is adopted. Some sensitive equipment are separated physically, so as to effectivly protect testing personnel and equipment.
