技术领域technical field
本发明涉及一种进出多分裂导线电场的辅助装置及方法。The invention relates to an auxiliary device and method for entering and exiting the electric field of a multi-split wire.
背景技术Background technique
近年,我国输电线路得到迅速发展,电网规模日益扩大,电网运行稳定性要求高,常需等电位作业进行消缺或安装在线监控设备。然而,500kV及以上电压等级线路,由于传统作业工法存在的技术局限性以及等电位作业的安全性要求,使等电位作业面临诸多难题。In recent years, my country's transmission lines have been developed rapidly, the scale of the power grid is expanding day by day, and the requirements for the stability of the power grid operation are high. Equipotential operations are often required to eliminate defects or install online monitoring equipment. However, for 500kV and above voltage lines, due to the technical limitations of traditional working methods and the safety requirements of equipotential work, equipotential work faces many difficulties.
通常,带电作业相关规程、导则规定:输电线路耐张杆塔进出等电位方式为“跨二短三”法(为尽可能小地占用绝缘空气间隙,手和脚跨过两片绝缘子、短接三片绝缘子),由于实践经验表明,当两串绝缘子间水平距离超过60cm时,作业人员手、脚之间距离过大,无法按照“跨二短三”技术要求的“手脚同步横向移动”,作业风险和劳动强度极大,同时,若缺陷位置处于两档中间位置或直线塔附近时,通过“跨二短三”法进入电场后,作业人员还需经过走线才能到达作业位置,耗时耗力。Usually, the relevant regulations and guidelines for live work stipulate that: the equipotential method of entering and exiting the tension tower of the transmission line is the "cross-two-short-three" method (in order to occupy the insulating air gap as small as possible, hands and feet cross two insulators, short-circuit Three pieces of insulators), due to practical experience, when the horizontal distance between two strings of insulators exceeds 60cm, the distance between the hands and feet of the operator is too large, and it is impossible to "synchronously move the hands and feet laterally" according to the technical requirements of "crossing two shorts and three", The operation risk and labor intensity are extremely high. At the same time, if the defect position is in the middle of the two gears or near the straight tower, after entering the electric field through the "cross-two-short-three" method, the operator still needs to go through the wiring to reach the working position, which is time-consuming exhausting.
此外,其他传统带电作业进出电场工法如硬梯法、软梯法(地面软梯法、地线软梯法)、吊篮法等,在适用电压等级、输电线路塔形等方面都存在限制条件,特别是对于同塔多回线路、紧凑型线路,塔头间隙尺寸较小、杆塔布置及环境复杂,无法通过传统工法安全、高效、快速实现等电位,不利于带电作业的安全开展。In addition, other traditional live work access methods such as hard ladder method, soft ladder method (ground soft ladder method, ground wire soft ladder method), hanging basket method, etc., have restrictions on the applicable voltage level and transmission line tower shape, etc., especially For multi-circuit lines and compact lines on the same tower, the gap between tower heads is small, the layout of towers and the environment are complex, and it is impossible to achieve equipotentiality safely, efficiently and quickly through traditional construction methods, which is not conducive to the safe development of live work.
如今,随着无人机等新型装备的应用,进出电场方式迎来新的发展。利用无人机将绝缘绳抛过导线,完成挂设,再使用电动升降装置从地面到达作业位置,然而,现有无人机结合电动升降装置进出电场方法采用抛绳方式,对于地理环境复杂及双回或多回线路,易出现绝缘绳磨损、脏污,影响作业安全,只适用于超特高压单回线路及同塔多回最下层导线,同时,回收绳索时直接抽绳回收,在复杂线路环境下,易缠绕至其他导线上,存在安全风险。Nowadays, with the application of new equipment such as drones, the way of entering and exiting the electric field has ushered in new developments. Use the UAV to throw the insulating rope over the wire, complete the installation, and then use the electric lifting device to reach the working position from the ground. However, the existing UAV combined with the electric lifting device uses the rope throwing method to enter and exit the electric field, which is difficult for the geographical environment. Complex and Double-circuit or multi-circuit lines are prone to wear and dirt on the insulating rope, which will affect the safety of the operation. In the line environment, it is easy to be entangled on other wires, posing a safety risk.

Since the body is provided with an insulating operating rope, the insulating operating rope can be hung on the multi-split conductor synchronously with the body. Since one end of the insulating operating rope is connected with the pull-down hook, when hanging The pull-down hook is always subjected to the pulling force of the insulating operation rope, and the pull-down hook cannot be separated from the body. When the pull-down hook receives a downward force, it can quickly escape from the connecting block. When the pull-down hook is released from the connecting block, the insulating operating rope is always fixed. On the pull-down hook, so one end of the insulated operation rope can be lowered to the ground with the pull-down hook. At this time, the operator can use the insulated operation rope as the climbing rope of the electric lifting device to enter and exit the electric field, thus eliminating the current combination of drones. The defects and limitations of the rope-throwing method used by the electric lifting device to enter and exit the electric field make it suitable for areas with complex geographical environments and complex lines with double or multiple circuits on the same tower, and can enter the traditional live work. Difficult-to-access compact towers and other special tower line positions, thereby eliminating the problem of insulation rope wear and dirt caused by the existing rope throwing method, improving the safety performance of the operation, setting an arc guide at one end of the body, and passing through the arc guide It plays a certain guiding and limiting function when the main body is hung, which further improves the hanging efficiency of the main body. The setting of the connecting block can increase the contact area between the pull-down hook and the connecting block, and improve the fixing quality of the pull-down hook. Finally, the The main body is configured as a structure of splints and pads, which can effectively reduce the weight of the entire main body.
