Abstract

?SISTEMA PARA SINALIZAR FALHAS EM DISTRIBUIÇÃO ELÉTRICA MONOFÁSICA?. Dispositivo sinalizador de falhas monofásico aplicável em redes aéreas de distribuição de energia elétrica para detectar a ocorrência de um curto-circuito na rede aérea de distribuição de energia elétrica a montante de seu ponto de instalação e sinalizar luminosamente tal evento. O auto ajuste à corrente de demanda instantânea da linha e a não sensibilidade às correntes de magnetizações dos transformadores de distribuição conectados à linha garantem confiabilidade de operação ao dispositivo. O sistema de fixação por grampo rosqueado e a sinalização de forma luminosa em todas as direções facilita tanto a instalação como a visualização do dispositivo. Opcionalmente o sinalizador pode incorporar um sistema interrogador que opera por comunicação remota sem fio possibilitando assim que, quando da ocorrência de uma falha, a sinalização luminosa ocorra somente quando o observador se aproxima do sinalizador de falha. O gabinete do sinalizador é inovador e é formado por uma metade traseira (26) e Dianteira (27) que se juntam através do suporte dos diodos emissores de luz (29) que é atravessado pela haste rosqueável do grampo de fixação (30) que mantém o dispositivo preso junto à fase da linha de distribuição monitorada (10). A parte eletrônica do dispositivo é formada por doze blocos: o detector de tensão (3) que recebe o sinal do sensor de tensão (l) que se encontra junto à linha de distribuição monitorada (10), o auto-teste (2) que simula uma falha, o sensor de corrente (4) que envia um sinal elétrico ao detector de sobre-corrente (5), os sinais proporcionais a tensão e a corrente são processados pela máquina de estados (8), o bloco de inicialização (6) gera o sinal que tem a função de zerar os blocos funcionais da máquina de estados (8) por ocasião da conexão da alimentação no circuito do dispositivo sinalizador de falhas ou por acionamento externo através da aproximação de um imã permanente (Im). O bloco oscilador (7) gera o sinal de relógio para o funcionamento do bloco máquina de estados (8). O circuito de saída (9) emite sinalização luminosa intermitente por ocasião da detecção pela máquina de estados (8), de uma falha na fase da rede de distribuição monitorada (10) e pelo acionamento do bloco receptor de interrogação (11) comandado remotamente pelo observador através do bloco emissor interrogador(12).?SYSTEM TO SIGNAL FAULTS IN SINGLE-PHASE ELECTRIC DISTRIBUTION?. Single-phase fault signaling device applicable in overhead power distribution networks to detect the occurrence of a short circuit in the overhead power distribution network upstream of its point of installation and luminously signal such an event. The self-adjustment to the instantaneous demand current of the line and the non-sensitivity to the magnetizing currents of the distribution transformers connected to the line guarantee the reliability of the device's operation. The threaded clamp fixing system and the luminous signaling in all directions facilitate both the installation and the visualization of the device. Optionally, the beacon can incorporate an interrogator system that operates via wireless remote communication, thus allowing that, when a failure occurs, the light signaling only occurs when the observer approaches the failure beacon. The beacon's cabinet is innovative and is formed by a rear (26) and front (27) half that are joined through the light emitting diodes support (29) which is crossed by the threadable rod of the fixing clip (30) that maintains the device attached to the phase of the monitored distribution line (10). The electronic part of the device is made up of twelve blocks: the voltage detector (3) which receives the signal from the voltage sensor (l) which is located next to the monitored distribution line (10), the self-test (2) which simulates a failure, the current sensor (4) which sends an electrical signal to the overcurrent detector (5), the proportional signals to voltage and current are processed by the state machine (8), the initialization block (6 ) generates the signal that has the function of resetting the functional blocks of the state machine (8) when power is connected to the circuit of the fault signaling device or by external activation through the approximation of a permanent magnet (Im). The oscillator block (7) generates the clock signal for the operation of the state machine block (8). The output circuit (9) emits intermittent light signaling when the state machine (8) detects a phase failure in the monitored distribution network (10) and when the interrogation receiver block (11) is activated remotely by the observer through the interrogator emitter block(12).
