运用于外导通钢绞线的登杆防坠装置设计

摘要

针对在防雷外导通中采用钢绞线和水泥杆登杆时没有保护措施，设计采用外导通钢绞线作为导轨的登杆防坠落保护装置，它具有差速闭锁功能可有效防止作业者在登杆时坠落，降低人员登杆作业的风险。%According to the unprotected state in pole climbing operation, an anti-falling device is proposed by using steer stranded wire which has a differential locking function and can effectively prevent falling in pole climbing operation.
