Description
"SENSOR ELETRÔNICO PARA CAPTURA DE SINAL ELÉTRICO""ELECTRONIC SIGNAL CAPTURE SENSOR"
A presente invenção refere-se a um sensor eletrônico para capturarsinais elétricos de uma linha energizada.The present invention relates to an electronic sensor for electrical captures of an energized line.
Atualmente no mercado, os sensores eletrônicos que capturam tensãoapresentam restrições na captura do sinal de tensão, pois utilizam a medição entrefase e terra, utilizando circuito resistivo.Currently in the market, electronic sensors that capture voltage present restrictions on the capture of the voltage signal, as they use phase-to-ground measurement using a resistive circuit.
Em relação ao sinal de tensão, como não existe um sistema deisolação elétrica adequado para permitir segurança de instalação e de operação ao1 operador que ira efetuar esse serviço, sua medição torna-se muito perigosa, poispode ocasionar descarga elétrica e causar acidentes.Regarding the voltage signal, as there is no adequate electrical isolation system to allow installation and operation safety to the operator who will perform this service, its measurement becomes very dangerous, as it can cause electric discharge and cause accidents.
Alem disso, o peso e volume desses sensores devido ao circuitoresistivo necessário para captura do sinal torna o método impraticável em algumassituações, devido ao espaço disponível para a instalação. Esses sensores sãoinstalados em linhas energizadas tendo-se que considerar questões ergonômicaspara o operador, e em muitos casos há linhas compactas em que há o empecilho dovolume pois o espaçamento entre as linhas é muito reduzido.In addition, the weight and volume of these sensors due to the resistive circuitry required for signal capture makes the method impractical in some situations due to the space available for installation. These sensors are installed on energized lines having to consider ergonomic issues for the operator, and in many cases there are compact lines where there is volume impediment because the line spacing is very small.
Nas linhas compactas os cabos são encapados, e os sensoresutilizados atualmente por serem resistivos obriga a perfurar o cabo da rede parapoder captar as leituras, pois necessita de contato elétrico para que o sinal sejarecebido. Assim o encapamento perde sua função de proteção, diminuindo a vidaútil do cabo.In compact lines the cables are shrouded, and the sensors currently used for being resistive require drilling the network cable to be able to capture the readings, because it requires electrical contact for the signal to be received. Thus the shroud loses its protective function, reducing the life of the cable.
