Description

technical field

[0001] The invention mainly relates to the field of distribution network technology, in particular to a distribution network fault indication system based on LoRa communication technology. Background technique

[0002] In the construction of distribution network automation, overhead fault indicators are more and more favored by power grid companies because they do not require modification of primary equipment and can be installed live, especially in suburban and rural distribution networks where loads are relatively dispersed.

[0003] Such as figure 1 As shown, the overhead fault indicator is mainly used for line fault monitoring and indication in the distribution network field; the functional module of the general fault indicator includes two parts: three acquisition units and one collection unit, of which the three acquisition units As the acquisition terminal of A, B, C three-phase load current and phase electric field, the acquisition unit sends the col...
