Abstract

FIELD: electric power net engineering. SUBSTANCE: method includes current spreading picture scaling by cable line feeding by direct current from unipolar source and magnetic field generated by this current following along cable trace by ferrozond teslameter using. Magnetic field polarity inversion or magnetic field disappearance, either drop down indicates damage location point. EFFECT: higher accuracy of damage location determining, shorter operation time.

Изобретение относится к электроэнергетике и может быть использовано для топографического определения места повреждения кабельных линий электропередач. Оно позволяет повысить точность измерений, снизить материальные затраты, сократить время поиска места повреждения, упростить методику поиска и применяемую аппаратуру. Отличительной особенностью предложенного способа является то, что для упрощения картины протекания тока в месте повреждения в кабеле создают магнитное поле неизменной полярности подключением источника постоянного по направлению тока, прослеживают эту полярность строго по трассе и фиксируют перемену полярности или исчезновение (резкое уменьшение) магнитного поля над местом повреждения прибором для измерения магнитных величин, например феррозондовым тесламетром.The invention relates to the electric power industry and can be used for topographic determination of the location of damage to cable power lines. It allows to increase the accuracy of measurements, reduce material costs, reduce the time to search for a place of damage, simplify the search methodology and the equipment used. A distinctive feature of the proposed method is that to simplify the picture of the current flow at the damage site, a magnetic field of unchanged polarity is created in the cable by connecting a constant current source in the direction, this polarity is monitored strictly along the track, and a polarity reversal or disappearance (sharp decrease) of the magnetic field above the spot damage by a device for measuring magnetic quantities, for example, a fluxgate teslameter.
