恶劣天气下基于张力反馈的紧线方法研究

摘要

恶劣天气下无法采用光学仪器对弧垂进行观测,这将导致输电线路无法紧线.若是抢修等紧急情况,则会对电网造成较大的损失.提出将悬垂绝缘子串偏斜影响考虑在内,推导了张力的精确计算公式,并设计了根据张力来判断弧垂大小的紧线施工方法.通过实际工程验证了方法的有效性.%Under severe weather,it is impossible make sag observation with optical instrument,and that will makestringing impossible on the power transmission line.In such emergencies as rush repair,the power grid would sufferconsiderable losses.This paper suggests that the impact of deflection of the suspension insulator string should be taken into account.Furthermore,it deduces a formula for accurate tension calculation,and designs a stringing method based on the sag judgment according to the tension.Practical engineering verifies the validity of the proposed approach.
