WIPO Patent Application WO/2019/221362
Kind Code:
A1
Abstract:
Disclosed are a self-power relay and a method for preventing a malfunction thereof. A self-power relay of the present invention comprises: a self-power generation unit for autonomously generating a driving power by performing conversion into a preconfigured driving power level by using, as a source power, a system power of a transmission/distribution line or power system; and a relay operation unit operated by a driving power, for measuring the amount of a system power of a transmission/distribution line or power system, blocking a system power transmitted to a load when a failure occurs, and monitoring a change in a source power of the self-power generation unit in real time, so as to stop a relay operation of the self-power generation unit and a relay operation of the relay operation unit itself when abnormality occurs, wherein a malfunction can be prevented by checking an unstable state of a source current and voltage for generation of a self driving power.
