Resumo: | The Disconnector is a switching device used in Substations, which connects the electrical circuit to the Substation and allows the protection of the system. Within a Substation, the ideal is that the equipment has remote activation. But in the case of the Disconnector, its drive is partially automated, as it may happen that the closing maneuver is not completed. In order to complete the closing of the electrical contacts remotely, there is a solution which consists in to fix an electromechanical vibration motor to the disconnector structure. The vibration produced by this device is transmitted to the main contacts, reducing the friction and residual stresses of the mechanisms, promoting their closure. To test this solution, a detailed three-dimensional model of the structure was made, and the analysis was done with a program that uses the Finite Element Method. The objective of the analyzes was to study the frequency of excitation of the electrical contact of the disconnector, to evaluate how the support structure of the disconnector behaves with the excitation that causes the contacts to fit, and to determine the frequency of the activation of the vibration motor electromechanical. After the threedimensional model was finalized, the boundary conditions were applied with the Ansys Workbench Ls-Dyna Software, and the natural frequencies of the system were identified. In order to validate the model, an experimental test was carried out to verify the natural frequencies. The values of natural frequencies were used to study the excitation of the electric contact, and a frequency value was obtained that produced good results in the displacement of the mobile contact, which was used to make several simulations in the Software. And with the simulations it was possible to evaluate the behavior of the structure with the vibration, and to determine the drive frequency and torque of the electromechanical vibration motor. |

Dissertação (Mestrado em Projetos e Processos de Fabricação) - Universidade de Passo Fundo, Passo Fundo, RS, 2019.http://tede.upf.br:8080/jspui/handle/tede/1858The Disconnector is a switching device used in Substations, which connects the electrical circuit to the Substation and allows the protection of the system. Within a Substation, the ideal is that the equipment has remote activation. But in the case of the Disconnector, its drive is partially automated, as it may happen that the closing maneuver is not completed. In order to complete the closing of the electrical contacts remotely, there is a solution which consists in to fix an electromechanical vibration motor to the disconnector structure.

Dentro de uma Subestação, o ideal é que os equipamentos tenham acionamento remoto. Mas no caso do Seccionador, seu acionamento é parcialmente automatizado, pois pode acontecer da manobra de fechamento não ser completada. Para concluir o fechamento dos contatos elétricos remotamente, apresenta-se uma solução que consiste em fixar um motor de vibração eletromecânica à estrutura do Seccionador. A vibração produzida por esse dispositivo é transmitida aos contatos principais, reduzindo o atrito e as tensões residuais dos mecanismos, promovendo o seu fechamento. Para testar essa solução, foi feito um modelo tridimensional detalhado da estrutura, e a análise foi feita com um programa que utiliza o Método dos Elementos Finitos. O objetivo das análises foi estudar com que frequências de excitação ocorreria o encaixe do contato elétrico do seccionador, avaliar como a estrutura de suporte do seccionador se comporta com a excitação que provoca o encaixe dos contatos, e determinar a frequência de acionamento do motor de vibração eletromecânica. Após o modelo tridimensional ser finalizado, foram aplicadas as condições de contorno com o Software Ansys Workbench Ls-Dyna, e foram identificadas as frequências naturais do sistema. Com o intuito de validar o modelo, foi realizado um ensaio experimental de verificação das frequências naturais. Os valores de frequências naturais foram utilizados para estudar as excitações de encaixe do contato elétrico, e chegou-se a um valor de frequência que produziu bons resultados em deslocamento do contato móvel, que foi utilizado para fazer diversas simulações no Software. E com as simulações foi possível avaliar o comportamento da estrutura com a vibração, e determinar a frequência de acionamento e o momento torçor do motor de vibração eletromecânica..Submitted by Aline Rezende (alinerezende@upf.br) on 2019-12-13T22:55:08Z No. of bitstreams: 1 2018MairaALMores.pdf: 25157202 bytes, checksum: 663c92bf9637a1cb1a7ae128228e57dd (MD5)Made available in DSpace on 2019-12-13T22:55:08Z (GMT).

Within a Substation, the ideal is that the equipment has remote activation. But in the case of the Disconnector, its drive is partially automated, as it may happen that the closing maneuver is not completed. In order to complete the closing of the electrical contacts remotely, there is a solution which consists in to fix an electromechanical vibration motor to the disconnector structure. The vibration produced by this device is transmitted to the main contacts, reducing the friction and residual stresses of the mechanisms, promoting their closure. To test this solution, a detailed three-dimensional model of the structure was made, and the analysis was done with a program that uses the Finite Element Method. The objective of the analyzes was to study the frequency of excitation of the electrical contact of the disconnector, to evaluate how the support structure of the disconnector behaves with the excitation that causes the contacts to fit, and to determine the frequency of the activation of the vibration motor electromechanical.
