Description

一种温度感应自动变谐振频率线路防振器 A temperature-sensing circuit automatically becomes the resonance frequency of vibration isolator

技术领域 FIELD

[0001] 本发明涉及一种防振器,特别涉及一种温度感应自动变谐振频率线路防振器。 [0001] The present invention relates to a vibration isolator, and particularly to a temperature sensing line automatically becomes the resonance frequency of vibration isolator.

背景技术 Background technique

[0002] 输电线的微风振动和输电塔的风振常会造成输电线断股断线、杆塔节点连接破坏等危害性极大的故障,多次造成影响严重的大面积停电事故。 [0002] aeolian vibration transmission lines and wind vibration transmission towers often cause great trouble off shares broken power lines, towers nodes connected destruction dangers, many severely affected by blackouts. 风致架空输电线路导线振动有三种形式:微风振动、次档距振荡和舞动,其中导线的微风振动发生得最为频繁,影响也最大。 Wind-induced vibration of the overhead power transmission line conductors of three forms: aeolian vibration, oscillation and galloping time span, wherein the wire aeolian vibration occurs most frequently, the greatest impact. 导线的微风振动是由于风垂直吹过导线时,在导线背后产生的周期性“卡门涡旋”激励作用,在导线上产生垂直导线和风向的作用力,使得导线产生微风振动。 Breeze is due to vibration of the wire wind blowing vertical wires behind the wire periodically generated "Karman vortex" incentives, vertical wires and wind force is generated in the wire, so that wire aeolian vibration is generated. 如果线路微风振动控制不当,将使输电线路极易发生诸如导线疲劳断股、金具磨损、杆塔构件损坏等故障,对线路安全带来较大的危害。 If the line is not properly controlled vibration breeze will make transmission lines prone to fatigue, such as off-strand wire, fittings wear, damage to the tower components, such as failure to secure the line to bring greater harm. 国内外经验表明,架空线路在沿海、沙漠、跨河、跨海等地形条件下容易发生严重的微风振动,没有防振保护措施的导线在两周内就可能导致疲劳断股,不但增加输电线路的功率损耗,造成电力浪费,甚至造成导线断裂而引起断电事故,严重威胁架空线的运行寿命,乃至输电线路的安全。 Domestic and foreign experience shows that overhead lines prone to severe vibration in the breeze along the coast, desert, across the river, sea and other terrain conditions, there is no anti-vibration protection within two weeks of lead can lead to fatigue broken stocks, not only increase transmission lines power loss, resulting in a waste of electricity, and even cause outages caused by lead fracture, a serious threat to the operational life of overhead lines, security, and transmission lines.

[0003] 导线的防振器作为防止导线振动的主要工具之一,当防振器的自谐振频率与输电线路的振动频率相匹配时候,可以良好地减少架空线路的谐振频率。 [0003] The vibration isolator wire as the main tool to prevent wire vibration when the vibration frequency of the self resonance frequency of the vibration isolator to the power line matches the time, the resonance frequency can be favorably reduced overhead lines. 但在我国高寒地区包括东北和内蒙等地,由于每年温差巨大,在不同季节架空导线的机械特性不完全相同。 But in our alpine region including the Northeast and Inner Mongolia and other places, due to the huge temperature difference a year, not exactly the same mechanical characteristics of the different seasons of overhead wires. 导致其自谐振频率实际上是处于受温度影响不断变化的过程中。 Results in self-resonant frequency is substantially affected by temperature it is in the process of changing. 而作为线路上使用的防振器,由于其谐振频率与温度相关。 As a vibration isolator for use on the line, because of its temperature dependent resonance frequency. 通常情况下,温度降低后,导线长度减少,导线刚度增加,导线的自谐振频率随之升高。 Typically, the temperature is lowered, the wire length is reduced, increasing the stiffness of the wire, the wire self-resonant frequency will be increased. 而防振器的自谐振频率在不同温度下,变化较小。 The self-resonant frequency of the vibration isolator at different temperatures, small changes. 因此难以适应高寒地区大温差条件下线路防振的需要。 It is difficult to adapt to the needs of large temperature difference line anti-vibration conditions alpine region.
