Abstract

The embodiment of the invention provides a 10kV distribution line fault warning method and device. The method includes the steps that the on-off state information of a line and a real-time current value of the line are acquired from a database; when the real-time current value does not belong to a first preset current value range, the on-off state information shows the cut-off state, and the line is determined to be in the power loss state; a common-change real-time current value and a special-change real-time current value are acquired from the database; when the common-change real-time current value does not belong to a second preset current value range, the line is determined to be a common-change line, and a common-change line power loss alarm signal is given out; when the special-change real-time current value does not belong to a third preset current value range, the line is determined to be a special-change line, and a special-change line power loss alarm signal is given out. The method and device provided by the embodiment improve the power supply reliability of a power grid.

Description

technical field [0001] The present invention relates to the communication field, and more specifically relates to a method and device for 10KV power distribution line fault alarm. Background technique [0002] With the rapid development of my country's economy, the demand for electricity has increased greatly. However, natural disasters such as typhoons and thunderstorms often cause 10kV distribution line failures, resulting in power outages. [0003] When the 10kV distribution network fails, the emergency repair personnel can only know the basic situation through the customer's repair call to know that the 10KV power grid has failed, thereby reducing the reliability of the power supply of the power grid. [0004] To sum up, how to provide grid power supply reliability is an urgent problem to be solved at this stage. Contents of the invention [0005] In view of this, the present invention provides a method and device for 10KV power distribution line fault alarm, so as t...
