Abstract
The search for new methods and technologies to optimize services, making them cheaper, faster, and more efficient, is one of the main objectives of several economic sectors. In the electricity sector, and especially in the maintenance and expansion of distribution networks, this objective is extremely pertinent. These services find difficulties in current methods such as long execution time, large dimensions of the necessary equipment, difficulty in accessing the places of occurrences, and demand for numerous and highly qualified teams. This article presents the results of the ANEEL R&D project nº PD-00047-0085/2019, entitled “Mobile Emergency Tower for 69 and 138kV Subtransmission Lines”, executed by SENAI CIMATEC in partnership with Grupo Neoenergia. The project aimed to develop a prototype of a Mobile Emergency Tower, trellised, modular, and towed by a vehicular platform, with an elevation of the tower structure carried out remotely by a system controlled by an operator on the ground and that can be used in maintenance and construction services for the new 69 to 138 kV subtransmission lines. The prototype developed and patented in the project allowed greater mobility and agility concerning conventional operation, as it uses 6061-T6 aluminum alloy, being transported by a 4x4 vehicle to facilitate the approach to the subtransmission lines, in addition to its assembly and elevation taking place through a tilting system controlled by an operator on the ground. In this way, service time was optimized, the system provided greater safety to operators and the number of people involved in the work team was reduced. When the equipment is integrated into the distributor's maintenance routines, it is expected to see a decrease in operating costs and a faster restoration of electricity. To validate the functioning of the prototype, it was submitted to several resistance simulations and physical tests, such as bending and traction of the structure, mobility in places of difficult access, activation of the remote tilting system, and assembly of the Tower in different configurations, single, double, and anchor circuits for lines from 69 to 138kV. Because of the results obtained, it was possible to conclude that the prototype of the Mobile Emergency Tower met the mechanical, structural, and application requirements for maintenance occurrences in subtransmission lines, which require the fast implementation of a structure to restore the electrical supply.
