| titleOfInvention | A kind of transformer core and clamp earthing current monitoring device |
| abstract | The utility model provides a kind of transformer core and clamp earthing current monitoring device, comprising: centre path current sensor and monitoring unit；The centre path current sensor is connected with the monitoring unit；The ground line of transformer core and the ground line of apparatus for fixing transformer are passed through from the center hole of the centre path current sensor respectively；The centre path current sensor is used to acquire the current value on each ground line；The monitoring unit is used to judge whether iron core multipoint earth faults occurs according to the size of the current value on each ground line got.The utility model embodiment is by the way that centre path current sensor to be mounted on the ground line of transformer core and apparatus for fixing transformer, when there are multipoint earth faults in iron core, flowing through the electric current on Transformer Core Grounding line can significantly increase, so can accurately and in real time be diagnosed to be iron core multipoint earth faults by the size of current value on monitoring iron core lead-out wire. |
