Claims (1)

Способ диагностики электроэнергетического оборудования высокого и сверхвысокого напряжения путем отключения оборудования с последующей подачей на него напряжения номинальной частоты и определения реакции объекта на приложенное напряжение, отличающийся тем, что с целью упрощения и сокращения времени диагностики перед отключением объекта определяют его поврежденную фазу и после отключения оборудования подключают только одну неповрежденную фазу объекта к сетевому напряжению, измеряют напряжение на отключенных фазах объекта, судят по уровням напряжений на отключенных фазах о наличии на них замыканий на землю и междуфазных замыканий между невключенными фазами и включенной фазой, в противном случае подключают к сетевому напряжению одну из поврежденных фаз оборудования, измеряют напряжение на второй поврежденной фазе и по его уровню судят о наличии на двух последних фазах оборудования междуфазного замыкания.A method for diagnosing electric power equipment of high and extra-high voltage by turning off the equipment and then supplying it with a voltage of the nominal frequency and determining the reaction of the object to the applied voltage, characterized in that in order to simplify and reduce the diagnostic time before disconnecting the object, its damaged phase is determined and after disconnecting the equipment they connect only one undamaged phase of the object to the mains voltage, measure the voltage on the disconnected phases of the object, judge the voltage levels on the disconnected phases; the presence of earth faults and phase-to-phase faults between the non-connected phases and the switched-on phase; otherwise, one of the damaged phases of the equipment is connected to the mains voltage, the voltage on the second damaged phase is measured and its presence is judged on the last two phases of the equipment phase-to-phase circuit.
