The device beacon faults single-phase applicable in overhead electric power distribution networks

摘要

The device beacon faults single-phase applicable in aerial networks of electric power distribution to detect the occurrence of a short circuit in the network overhead electric power distribution, the amount of its point of installation and signal luminously such event.The self adjustment to the current instant demand of line and non sensitivity to current magnetizau00e7u00f5es of distribution transformers connected to the line to ensure reliable operation of the device. The system is fixed by clamp attached to a light signal in all directions facilitates the installation and the display of the device.Optionally the beacon interrogator may incorporate a system that operates by remote wireless communication allowing, when a failure has occurred, the signalling occurs only when the observer moves closer to the beacon of failure.The office of the beacon is innovative and it is formed by a rear half (26) and front (27) which are joined through the medium of light emitting diodes (29) which is traversed by the shank threadable attachment clamp (30) which maintains the device stuck with the phase of the line of deliveries. Constitution a monitor (10).The electronics of the device is formed by twelve blocks: the voltage detector (3) which receives the sensor signal voltage (L) which is next to the distribution line monitored (10), the self test (2) that simulates a fault, the current sensor (4) which sends an electrical signal to stop Ctor on current (5),The signals proportional to the voltage and current are processed by the state machine (8), the boot block (6) generates the signal which has the function of resetting the functional blocks of the state machine (8) on the occasion of the connection of the feeding circuit device beacon of F. ALHAS or external drive through the approximation of a permanent magnet (IM).The block oscillator (7) generates the clock signal for the operation of the block state machine (8).The output circuit (9) emits light signalling flashing on the occasion of the detection by the state machine (8), a failure in the stage of distribution network monitored (10) and the drive block receiver mark (11) is controlled remotely by the observer through bl Hollow emitter interrogator (12).
