| In order to carry out the research on the new method,new equipment and new construction method of the experimental platform for live operation of transmission line of distribution network,a movable transmission line shift distance experimental platform is developed.A rail-type mobile platform is designed,which overcomes the problems of the transmission poles in the traditional distribution network,such as the gap transformation,pole type transformation and phase spacing transformation,and meets the requirements of the actual working conditions.After the completion of the construction of the experimental platform,it can meet the electrical operation related to the daily live operation of electric power technicians,and play a good role in training and guidance.In order to achieve the technical requirements of the experimental platform,to insure the safe and stable operation experiment platform under the actual working condition,the paper on the basis of extensive research literature at home and abroad,from the movement of experimental platform,drive mode and lose pole and the connection mode of platform,established a complete set of design scheme,select the experiment platform of the key parameters,The basic composition of the experimental platform includes moving trolley,transmission system,rod fixed structure and control system.The stability of transmission system and transmission pole is calculated.The 3D modeling software Solid Works is used to establish the 3D solid model of transmission line shift range experimental platform.Based on the virtual prototype theory of multi-body system,the 3D solid model is converted into the multi-body system dynamics simulation model,and then imported into the multi-body dynamics simulation analysis software ADAMS for simulation.According to the obtained results,The driving characteristics of the transmission line shift distance experimental platform system are analyzed.The results show that: the horizontal displacement of the transmission pole’s centroid of the mobile platform changes little,and the maximum amount mainly occurs in the start-up and stopping stages.The wheel-rail contact is good,and no overturning will occur.It verifies that the overall design of the mobile platform is reasonable and ensures the functions and safety and stability of the platform.After the ADAMS simulation analysis,the physical prototype is manufactured and tested,and it is found that the prototype runs smoothly and safely.According to the virtual prototype technology,it can provide a theoretical basis for the platform construction of subsequent vehicles and the direction of system model optimization. |
