SYSTEM FAILURE DIAGNOSIS AND FORECASTING Electrocontact FIRES

摘要

The invention relates to the field of elektropozharnoy security and electricity, namely to devices electrocontact diagnostics of failures and prevent fires. diagnosing electric contact failure system and prediction of fires, comprising an electric power line connected thereto electrical and control device including a measuring unit, a generating a frequency spectrum, the output of which is linked to the accumulation unit via the series-connected blocks amplification and rectification, wherein the storage unit output is connected to input of the comparator, the first output of which is connected to the actuating body disable e. network via a command generating unit and the storage unit via the input delay unit connected to the second output of the comparator; additionally introduced multiplexer, receiving unit, transmitting nodes associated with current transformers are connected to power circuits each installation, the unit generating a frequency spectrum input coupled to the output of the multiplexer, the first input of which is connected to the control unit, the second - a yield measurement unit, and the third - with the output of the receiving unit.
