Resumo: |
This paper proposes the implementation of a new type of switch fuse to be used in areas with high saline pollution, to reduce significantly the occurrences of lack of improper switch fuses and thereby improve the rates of DEC and FEC. Distribution networks were used as field experiment in the towns of Aracati, Fortim and Icapuí, in which there was an excellent performance of the switch fuse with double insulation for situations where there is a high rate of saline pollution. The switch, which is in the form of fuse, is a device composed of elements designed to protect the circuit from damage and dynamic effects resulting from faults in power distribution system. The use of double isolated switch fuse was responsible for the reduction of saline pollution occurrences in the dry season. To achieve this type of switch fuse, several prototypes were developed to try the elimination the leakage current caused by pollution saline. By using this new equipment, we could see the preservation of fuse links and the reduction of improper operations records, which caused an increase in working time of staff, loss of material and especially customer dissatisfaction. This paper emphasizes the main features of this new model of switch fuse when it comes to reliability and security of energy supply. |
