High-tension line running status method for inspecting
Technical field
The present invention relates to the high-tension line damage detecting method, the method that the inspection device that particularly a kind of utilization is walked detects high-tension line on the hanging net operation circuit.
Background technology
In recent years, construction along with the high-tension line backbone network, the ultra-high-tension power transmission line of hanging net operation is more and more, operational defect also progressively comes out simultaneously, for example: disconnected strand of the outer strand of the OPGW Optical Fiber composite overhead Ground Wire that frequency is occurred frequently, the disconnected thigh of this skin not only forms communication security and threatens, and along with the increase of its broken lot length, the reduction of permanent way machine intensity also can constitute serious threat to the safety of transmission line.According to the disconnected stock market-circumstance condition investigation statistics of power transmission line, disconnected strand generally is that outer monofilament takes place disconnected strand, therefore, can adopt the video image routine inspection mode to disconnected the patrolling and examining of stock market-circumstance condition of power transmission line.
At present, method for inspecting commonly used is the manual inspection method, and this method workload is big, condition is arduous, it is low to patrol and examine precision, particularly to the mountain area with cross over patrolling and examining of great rivers circuit, there is very big difficulty, even has some projects of patrolling and examining to be difficult to finish by conventional method.For reach the purpose of patrolling and examining comprehensively, the method for inspecting of helicopter aerial survey has appearred, and precision and efficient are all higher, but owing to maked an inspection tour condition effect such as regional geography, weather, have potential safety hazard, and line walking expense height.In addition, also occurred directly at the up equipment of walking to detect of patrolling and examining of transmission line, but the mode of this device spanning obstacle has determined it to have the not strong shortcoming of obstacle climbing ability.
Therefore, need a kind of method that the circuit operation conditions is patrolled and examined of research and development, overcome above-mentioned deficiency,, effectively avoid disconnected burst of damage of transmission line to cause accident, ensure the safe operation of power system communication with disconnected burst of damage of timely discovery transmission line.
Summary of the invention
In view of this, the invention provides a kind of high-tension line running status method for inspecting, can replace manual inspection to realize the high accuracy of high-tension line is patrolled and examined by this method, and the obstacle detouring mode of inspection device is with respect to the obstacle detouring mode of existing inspection device in this method, its obstacle climbing ability is stronger.
