本发明涉及输电线路技术领域，具体涉及一种用于输电线路覆冰的检测处理装置。The invention relates to the technical field of power transmission lines, in particular to a detection and processing device for ice coating of power transmission lines.
背景技术Background technique
近年来随着城市和工业的不断发展，电力需求急剧增加，而水力、火力和原子能等大规模发电设备都远离城市。特别在中国“西电东送”、“北电南送”的格局下，高电压、大容量输电线建设成己成为输电网络发展的必然趋势。随着电力基础设施的不断建设，输电线路规模不断扩大，输电线路电压等级也越来越高，高压甚至超高压的远距离电力输送也正在逐步建设，我国电力工业已进入了以大机组、高电压、高自动化为特征的大电网时代，成为了关系国民经济与社会可持续发展的基础性行业和支柱性产业。In recent years, with the continuous development of cities and industries, the demand for electricity has increased dramatically, and large-scale power generation equipment such as hydropower, thermal power and atomic power are far away from cities. Especially under the pattern of "transmitting electricity from west to east" and "transmitting electricity from north to south", the construction of high-voltage and large-capacity transmission lines has become an inevitable trend in the development of power transmission networks. With the continuous construction of power infrastructure, the scale of transmission lines has been continuously expanded, the voltage level of transmission lines has become higher and higher, and high-voltage and even ultra-high-voltage long-distance power transmission is also being gradually built. The era of large power grids characterized by voltage and high automation has become a basic industry and a pillar industry related to the sustainable development of the national economy and society.
经济社会日益增强的电力依赖性，促使了电力供应安全的地位比以往任何时候都更加重要，其中电网是输送和分配电能的重要环节，然而，当前电网的现实情况是：重低温、雨雪、冰冻灾害天气经常给偏远地区和山区造成大面积停电事故，网架结构受到重破坏，在电网迎峰度冬期间受低温雨雪天气影响，输电线路的“微气象区”或其他区域，由于雾凇、雨凇形成导致输电线路导、地线覆冰后弧垂下降，造成地线与导线距离不足，引起导线对地线放电、导线覆冰后相间距离不足引起线路跳闸。The increasing dependence on electricity in the economy and society has made the status of power supply security more important than ever. The power grid is an important link in the transmission and distribution of electrical energy. However, the current reality of the power grid is: heavy low temperature, rain and snow, Freezing disasters often cause large-scale power outages in remote areas and mountainous areas, and the grid structure is severely damaged. During the peak winter period of the power grid, it is affected by low-temperature rain and snow weather, and the "micro-meteorological zone" or other areas of the transmission line are affected by the rime. The formation of rain scorpion causes the transmission line conductor and ground wire to sag after icing, resulting in insufficient distance between the ground wire and the wire, causing the wire to discharge to the ground wire, and the line tripping due to insufficient phase-to-phase distance after the wire is iced.
目前，输电线路去除覆冰的方法有很多种，但简单、有效的不多。常用的方法有加热融冰法，其除冰原理是使输电线路流过大电流，通过线路电阻发热升温融化覆冰，但这种方法必须先对输电线路进行断电处理，然后在覆冰段线路施加大电流的直线电流，通过线跳路本身的电阻发热，使覆冰现化，这种方法需要断电后才能操作，往往影响线路工作。在机械性除冰通过敲击和振动的方式上，而现有的机械性除冰的行驶小车，大多采用多组滚轮与输电线路结合，这种方式可能会在高频的机械性震动下滚轮和输电线路脱轨，同时在输电线路表面覆冰的情况下，滚轮与输电线路之间的滑动摩擦力较小，可能会影响滚轮的有效行驶。以往还有使用人工去除输电线路覆冰的方法，经观察发现除冰效果不好、效率不高，有时难以实施。At present, there are many methods for removing ice from transmission lines, but few are simple and effective. The commonly used method is the heating and melting ice method. The principle of deicing is to make the transmission line flow a large current and heat up through the line resistance to melt the ice. The line applies a high-current linear current, which generates heat through the resistance of the line jumper itself, so that the icing is realized. This method can only be operated after the power is cut off, which often affects the work of the line. In mechanical deicing by knocking and vibrating, most of the existing mechanical deicing trolleys use multiple sets of rollers combined with transmission lines. This method may cause the rollers to roll under high-frequency mechanical vibration. When the transmission line is derailed and the surface of the transmission line is covered with ice, the sliding friction between the roller and the transmission line is small, which may affect the effective running of the roller. In the past, there was also a method of manually removing ice from transmission lines. After observation, it was found that the deicing effect was not good, the efficiency was not high, and it was sometimes difficult to implement.
发明内容SUMMARY OF THE INVENTION
本发明的目的在于提供一种用于输电线路覆冰的检测处理装置，以解决现有技术中热力型除冰热力型除冰需要使得输电线路处于不工作状态，施加过负荷的电流使得输电线路发热进而实现除冰，该种方式在影响输电线路的供电的同时除冰的效率也不是十分的理想，以及机械除冰的行驶小车的行驶弊端的技术问题。The purpose of the present invention is to provide a detection and processing device for icing of power transmission lines, so as to solve the need of thermal type deicing in the prior art to make the power transmission lines in a non-working state, and to apply an overloaded current to make the power transmission lines Deicing is achieved by generating heat.

其中，第一执行机构1和第二执行机构2具体的基础参考结构是现有的用于高压输电线路进行多条输电线路(本发明中是以四条输电线路为例)连接的间隔棒，且第一执行机构1和第二执行机构2的利用导线连接电源进行供电，导线可设计成可收卷的放线方式，用来跟随第一执行机构1和第二执行机构2在输电线路上的移动。The specific basic reference structure of the
由于在偏远以及高山地区，架设输电线路较为困难，并且在后期的输电线路的维护也是一个难题，重低温、雨雪、冰冻灾害天气经常使得偏远地区和山区造成大面积网架结构受到重破坏，由于偏远地区和山区的路况和环境限制，工作人员无法频繁的对线路进行维护以及对输电线路的覆冰进行清理，尤其是在跨越地形上，为此：Due to the difficulty in erecting transmission lines in remote and high mountain areas, and the maintenance of transmission lines in the later period is also a difficult problem, severe low temperature, rain and snow, and freezing disasters often cause large-scale grid structures in remote areas and mountainous areas. Due to the road conditions and environmental restrictions in remote areas and mountainous areas, the staff cannot frequently perform maintenance on the lines and clear the ice covering of the transmission lines, especially on the crossing terrain. To this end:
本发明的第一执行机构1和第二执行机构2通过导线电性连接，第一执行机构1包括整形机构3和振动发生机构5，第二执行机构包括破冰机构4和位移发生机构6。The
由于雾凇、雨凇以及风力、重力的多重因素的作用下，使得输电线路表面的覆冰并不是成规整的形状，而现有的输电线路的覆冰除冰方式包括热力型除冰和机械性除冰，热力型除冰需要使得输电线路处于不工作状态，施加过负荷的电流使得输电线路发热进而实现除冰，该种方式在影响输电线路的供电的同时除冰的效率也不是十分的理想。Due to the multiple factors of rime, rain, wind and gravity, the icing on the surface of the transmission line is not in a regular shape, and the existing methods of icing and deicing of transmission lines include thermal deicing and mechanical deicing. De-icing, thermal de-icing needs to keep the transmission line in a non-working state, and applying an overloaded current makes the transmission line heat up to achieve de-icing. This method affects the power supply of the transmission line and the efficiency of de-icing is not very ideal. .
在机械性除冰通过敲击和振动的方式上，而现有的机械性除冰的行驶小车，大多采用多组滚轮与输电线路结合，这种方式可能会在高频的机械性震动下滚轮和输电线路脱轨，同时在输电线路表面覆冰的情况下，滚轮与输电线路之间的滑动摩擦力较小，可能会影响滚轮的有效行驶；In mechanical deicing by knocking and vibrating, most of the existing mechanical deicing trolleys use multiple sets of rollers combined with transmission lines. This method may cause the rollers to roll under high-frequency mechanical vibration. When the transmission line is derailed, and the surface of the transmission line is covered with ice, the sliding friction between the roller and the transmission line is small, which may affect the effective running of the roller;
再者，采用产生高频振动的方式中，由于输电线路的长度较长，振动源在的振动波在输电线路上的传导会减弱，为此：Furthermore, in the method of generating high-frequency vibration, due to the long length of the transmission line, the conduction of the vibration wave from the vibration source on the transmission line will be weakened. For this reason:
本发明在对输电线路的覆冰的处理上，主要通过以下两个方面来实现：The present invention mainly realizes the following two aspects in the treatment of the icing of the transmission line:
首先，通过整形机构3将输电线路上的覆冰切削成指定形状，即通过整形机构3将输电线路上形成的不规则覆冰，切削成套在输电线路上的规则圆柱状，并在圆柱状的覆冰的表面沿轴向开设扭矩沟槽，破冰机构4用于对扭矩沟槽施加切向扭矩力，开设扭矩沟槽为破冰机构4提供施力点，进而完成对圆柱状的覆冰的削除，由于沿所述输电线路的径向开设扭矩沟槽，使得圆柱状的覆冰内部结构被破坏，从而能够轻易的除去覆冰。First, the ice coating on the transmission line is cut into a specified shape by the
其次，振动发生机构5用于在若干条输电线路上发生高频振动，位移发生机构6用于在振动发生机构5驱使输电线路发生高频振动的同时驱动若干条输电线路发生周期性的向心移动，位移发生机构6产生输电线路的向心移动形成振动发生机构5在输电线路上的振动传递的断点，将输电线路的高频振动截留在振动发生机构5和位移发生机构6之间的输电线路上。Secondly, the vibration generating mechanism 5 is used to generate high-frequency vibration on several transmission lines, and the
现有的利用高频振动的方式进行覆冰的去除，由于覆冰内部与输电线路的粘接结构较为紧密，单纯的高频振动无法有效的去除，并且高频振动在传递的过程中能量消散也十分的明显。The existing high-frequency vibration method is used to remove the icing. Because the bonding structure between the inside of the icing and the transmission line is relatively close, the simple high-frequency vibration cannot be effectively removed, and the energy of the high-frequency vibration is dissipated during the transmission process. Also very obvious.
本发明中的振动发生机构5和位移发生机构6的其工作原理是，在第一执行机构1和第二执行机构2的间隔棒作用下，使多条输电线路之间的距离相同，而在输电线路的重力的影响下，第一执行机构1和第二执行机构2存在高度差，并且随着第一执行机构1和第二执行机构2之间的距离增大，第二执行机构2位于低势能区，而该处受到风力和气温的影响作用最大，输电线路的动态表征也较为明显。The working principle of the vibration generating mechanism 5 and the
为此，当振动发生机构5产生高频振动时，位移发生机构6在较为低势能区将多条输电线路向心拉动，其作用是，位移发生机构6在输电线路的某处施加径向的拉力，使得振动发生机构5产生的高频振动存在到达位移发生机构6处被抵消或者减弱，而这种抵消或者减弱将对沿输电线路的高频振动一个快速的反馈，使得振动发生机构5和位移发生机构6之间的输电线路的表面应力增大，进而提高震动发生机构5在该段输电线路上的作用效果；For this reason, when the vibration generating mechanism 5 generates high-frequency vibration, the
同时，高空输电线路在重力和风力的作用下出现摆动，而这种摆动在实际的过程中受到的影响因素较多，利用基于流体力学理论的典型覆冰导向-新月形覆冰导线气动特性分析模型的分析下可以得出，通过位移发生机构6拉动四个输电线路，在输电线路的铁塔对输电线路的拉力，使得该处的线路呈紧绷状态，而由于输电线路在此处的重力均向下，因此在输电线路受到任何攻角的风力时都会使多个输电线路以位移发生机构6的几何中心发生一定的自旋转动，而此时由于振动发生机构5较为靠近其自旋转动不够明显或不自旋转动，因此作用在振动发生机构5和位移发生机构6的作用和限制下，输电线路上产生的应力将从覆冰和输电线路的粘结表面破坏输电线路上的覆冰。At the same time, the high-altitude transmission line swings under the action of gravity and wind, and this swing is affected by many factors in the actual process. The aerodynamic characteristics of the typical ice-covered guide-crescent-shaped ice-covered wire based on the theory of fluid mechanics are used. According to the analysis of the analysis model, it can be concluded that the four transmission lines are pulled by the
