潘家口大坝坝顶引张线自动化改造几个问题的讨论

DISCUSSION ON AUTOMATION REFORMATION OF WIRE ALIGNMENT SYSTEM OF PANJIAKOU DAM

实现引张线自动化监测与传统的人工监测相比有许多问题需要解决，如坝顶系统的防雷、抗干扰问题，引张线系统浮船浮液的防结冰，防蒸发问题、引张线线体的热胀冷缩问题等。介绍了潘家口大坝坝顶引张线系统在实施过程中解决上述几个问题的措施。

Compared with a manual monitoring system. the automatic wlre alignment monitoring system has many problems to be solved. for example. the transient suppression. anti-disturbance. anti-freeze and anti-vaporization of the liquid in float box. temperature deformation of the wire. etc. Introduced in the paper are some methods for solving the above problems in the wire alignment system on the Panjiakou Dam crest.
