April 13, State Grid Jiangsu Power Company independently developed by the first set of remote transmission lines at home and abroad remote laser rapid removal instrument successfully 35,000-volt Dai-Changzhou 3541 line hanging kite charged removal, marking the overhead lines of foreign body charged Clear technology has made new developments. It is reported that the overhead line foreign body hanging line is caused by unplanned outage one of the main reasons. At present, the removal methods include uninjured spit fire and insulated arm-car lift-off, etc. However, the above technologies or the removal of the instrument from the live line have a security risk too close to the live line or require long time labor, high labor intensity and high labor risk . To this end, two years ago, the State Grid Jiangsu Electric Power Transmission Line full investigation of foreign objects on the basis of creatively proposed the use of remote laser rapid removal of foreign matter method, that is, the appropriate energy of the laser beam to the transmission line at longer distances Foreign body, in ensuring the safety of the conditions will be wound on the wire on the part of the burn, so that foreign objects fall. The invention won the national invention patent on September 24, 2014. After nearly two years of laser system hardware research and repeated commissioning of nearly three months, the hospital has finally completed the development of product prototype. The set of prototypes uses far-infrared laser, can effectively act on the transmission line within 60 meters, to achieve the removal of foreign matter quickly and effectively under the condition of the line is charged. On April 13, when State Grid Jiangsu Power was informed of the existence of a kite hang line on Dai Feng Line, it immediately rushed to the scene to carry out a lack of operation. The site survey found that kite hang line location is located at a crossroads, on-site intensive, traffic flow, timely arrangement can not be cleaned live work. The company professionals in the field full view, the exact choice of laser rapid clearance instrument placement, reasonable arrangements for the kite main and kite line removal sequence, the successful completion of foreign body removal. Next, the State Grid Jiangsu Electric Power will be combined with the actual needs of the scene, continued transmission lines remote laser rapid clearing instrument applied research and site promotion.
