Description

[Detailed description of the invention]

[0001]

[Technical field to which the invention belongs]

 The present invention relates to a distribution line terminal disconnection detection device that automatically collects disconnection information of a power failure / recovery at a customer's house at the end of a distribution line into a monitoring center.

[0002]

[Prior art]

 As for the disconnection information of power failure / recovery in the conventional household distribution line, the power meter installed in the monitoring system on the power transmission side can be used to grasp the information, or rely on the personal information on the power receiving side by telephone notification from the resident on the user side. It was only the situation, and the return information could not be expected.

[0003]

[Problems to be solved by the device]

 When the disconnection information is grasped by a power meter or the like equipped in the conventional transmission-side monitoring system, if the distribution line forms a closed loop, it is possible to somehow estimate the disconnection location and confirm it on site. In the case of an open distribution line at the end of the distribution line, it is difficult to even estimate, and it is only possible to rely on personal information from the residents such as telephone notifications, and return information cannot be expected. There was a problem that requires labor.
