    • PROBLEM TO BE SOLVED: To provide a method of preventing a cable disconnection capable of surely preventing an occurrence of situation where a cable is accidentally disconnected by allowing the cable to move smoothly so as to secure an extra length of the cable, even when a great tensile force is suddenly applied to the cable caused by an occurrence of an uneven settlement of the ground in the region where the cable is laid due to an earthquake.SOLUTION: According to the method of preventing a cable disconnection of the present invention, a part of cable laid in facilities is placed on a plurality of rollers arranged with predetermined spaces. Also, the cable maintains a state where it bends downwardly between adjoining rollers. When a great tensile force is suddenly applied to a cable laid in various facilities due to an uneven settlement of the ground or the like during an earthquake, the cable, which is bending downwardly between adjoining rollers, moves smoothly so as to extend with the help of the rollers.
    • 要解决的问题:提供一种防止电缆断开的方法,其可以通过允许电缆平滑地移动以防止电缆意外断开的情况的发生,以确保电缆的额外长度,甚至 当由于地震而在电缆铺设的区域中由于地面不均匀沉积而引起的电缆突然施加大的拉力时。 解决方案:根据本发明的防止电缆断开的方法,将放置在设施中的电缆的一部分放置在以预定空间布置的多个辊上。 此外,电缆保持其相邻辊之间向下弯曲的状态。 当在地震期间由于地面等沉积不均匀而突然施加到各种设施中的电缆的大张力时,相邻辊之间向下弯曲的电缆平滑移动,以便在帮助下延伸 的辊子。 版权所有(C)2012,JPO&INPIT
