Description

technical field [0001] The invention relates to the technical field of residual current detection equipment for isolated power supplies, in particular to a residual current monitoring device. Background technique [0002] The isolated power supply is a common power supply equipment in medical places. Compared with the transmission power supply, it has the advantage of not being grounded, which greatly improves the safety of use. During the use of the isolated power supply, it needs to integrate a residual current monitoring device inside. It is used for real-time detection of residual current in the circuit loop, and an alarm function is issued when residual current is detected to improve safety efficiency. [0003] At present, in the detection process of the existing residual current monitoring device, the magnetic ring is generally used to set the wire on the wire. Using the principle of magnetoelectricity, when a residual current is generated somewhere in the wire, due to...

Problems solved by technology

[0003] At present, during the detection process of the existing residual current monitoring device, the magnetic ring is generally used to set the wire on the wire. Using the principle of magnetoelectricity, when a residual current is generated somewhere in the wire, due to the change of the magnetic field, the magnetic ring is wound outside. In this way, although the effect of residual current monitoring can be realized, because the wire is located in a place where multiple power equipments are concentrated, there is a certain amount of magnetic field interference around it, and the width of the magnetic ring is small, so it is difficult to detect Each position of the wire is detected, which reduces the effect of residual current monitoring
