Description

DESCRIZIONE dell?invenzione avente per titolo: ?Dispositivo supervisore di sicurezza per reti elettriche comunque complesse, operante in tempo reale, facente uso di opportune frequenze impresse per il rilevamento di rotture cavi e/o di accidentali contatti a terra con conseguente intervento di azioni protettive?; DESCRIPTION of the invention entitled:? Safety supervisor device for electrical networks, however complex, operating in real time, making use of appropriate impressed frequencies for the detection of cable breaks and / or accidental earth contacts with consequent intervention of protective actions ?;

Come ? noto esistono attualmente grossi problemi di sicurezza per le persone relativi alle reti elettriche aeree in aree urbane a causa di possibili rotture di cavi o di contatti accidentali a terra. A tutt?oggi non ci risulta che esistano dispositivi in grado di rivelare tali fatti accidentali e per, conseguentemente, disattivare la rete elettrica con immediatezza evitando il peggio. L?invenzione in oggetto ovvia a tali inconvenienti in quanto ? in grado di rivelare l?accaduto (rottura di cavi o contatti accidentali a terra) entro un tempo di frazioni di secondo e di operare immediatamente alla messa in sicurezza dalle stessa rete elettrica. Inoltre il dispositivo ? in grado di comunicare subito l?accaduto, con i relativi parametri, al centro operativo per il successivo intervento di ripristino della normalit? da parte del personale addetto. Il dispositivo pu? operare sia su reti a corrente alternata quanto su reti in corrente continua ed inoltre pu? essere operativo sia quando la rete elettrica ? in tensione sia anche qualora non lo fosse. How ? It is known that there are currently major safety problems for people relating to overhead electrical networks in urban areas due to possible cable breaks or accidental earth contacts. To date, there are no devices capable of detecting such accidental facts and consequently deactivating the electricity grid immediately, avoiding the worst. The invention in question obviates these drawbacks in that? able to detect what happened (breakage of cables or accidental earth contacts) within a fraction of a second and to immediately operate to make it safe from the mains itself. Also the device? able to immediately communicate what happened, with the relative parameters, to the operations center for the subsequent intervention to restore normality? by the staff. The device can? operate both on alternating current networks and on direct current networks and also can? be operational both when the power grid? even if it is not in tension.

La rete elettrica ? normalmente costituita da un insieme di maglie contigue. Un singolo dispositivo di protezione ? in grado di proteggere una maglia e pertanto sulla rete andranno montati tanti dispositivi di protezione quante sono le maglie da proteggere. Il principio di protezione si basa sull?invio in ciascuna maglia di opportune frequenze da parte del dispositivo e nella misura delle caratteristiche risultanti, condizionate dallo stato e dai parametri di linea. The electricity grid? normally made up of a set of contiguous links. A single protective device? able to protect a mesh and therefore as many protection devices must be mounted on the net as there are meshes to be protected. The protection principle is based on the sending of appropriate frequencies in each mesh by the device and on the measurement of the resulting characteristics, conditioned by the state and the line parameters.

Il trovato ? quindi dispositivo di rilevamento dello stato di anomalia, dispositivo attivo nel comandare l?azione di messa in sicurezza della rete ed, infine, dispositivo atto a comunicare immediatamente l?accaduto al centro operativo per le attivit? conseguenti. The found? then a device for detecting the state of anomaly, a device active in commanding the action of securing the network and, finally, a device capable of immediately communicating the event to the operations center for activities. consequent.

RIVENDICAZIONI 1) La realizzazione di dispositivi supervisori di sicurezza per reti elettriche, allocabili su una o pi? maglie delle stesse, facenti uso di frequenze impresse per rilevarne stati di rottura cavi e/o di accidentali contatti di terra. CLAIMS 1) The creation of safety supervisor devices for electrical networks, which can be allocated on one or more? meshes of the same, making use of impressed frequencies to detect broken cables and / or accidental earth contacts. 2) La possibilit? di intervento in tempo reale con relativa segnalazioni e/o comando protettivo mediante dispositivi supervisori di sicurezza a frequenze impresse operanti su reti elettriche comunque complesse. 2) The possibility? real-time intervention with relative signals and / or protective command by safety supervisor devices at impressed frequencies operating on electrical networks, however complex. 3) La possibilit? di procedere immediatamente alla tolta tensione della rete mediante dispositivo locale provocando la messa a terra di entrambi i conduttori della rete stessa. 3) The possibility? to proceed immediately with the disconnection of the mains voltage by means of a local device causing the earthing of both conductors of the network itself.
