Problems solved by technology

However, the existing magnetic latching relay does not have the leakage protection function. Therefore, the leakage protector and the magnetic latching relay need to work together to complete the leakage protection of the magnetic latching relay, so that the magnetic latching relay has the leakage protection effect

Abstract

The present invention designs a magnetic latching relay having an electric leakage protection function. The relay comprises a relay mounting rack, a side-hung door, a LED lamp, a cooling fan, an electric power storage box, a fire alarm, a leakage protector, a magnetic latching relay and a mounting rack. The magnetic latching relay is fixedly installed at one side of the mounting rack, the upper portion of the magnetic latching relay is provided with the electric power storage box, the leakage protector is fixedly installed at the other side of the mounting rack, the magnetic latching relay is electrically connected with the leakage protector, and the fire alarm is fixedly installed at one side of the top portion of the mounting rack. The present invention further provides the control circuit of the magnetic latching relay having the electric leakage protection function. The circuit comprises a power supply circuit and a control circuit which are mutually connected; and the executed control circuit comprises a driving circuit, the magnetic latching relay and a leakage determination circuit; the leakage protector is eclectically connected with the magnetic latching relay to allow the magnetic latching relay to have an electric leakage protection function so as to avoid fire hazard accidents or circuit paralysis.

Description

technical field [0001] The invention relates to the technical field of magnetic latching relays, in particular to a magnetic latching relay with leakage protection function and a control circuit thereof. Background technique [0002] Magnetic latching relay is an electronic control device, which plays the role of automatic adjustment, safety protection, conversion circuit, etc. in the circuit, and is widely used in power protection, automation, motion, remote control, measurement and communication devices. A magnetic latching relay usually includes a base, a yoke assembly, a magnetic steel assembly, a moving spring assembly, a static spring assembly, and a push piece. The coil is wound on the skeleton of the yoke assembly. When the current direction in the coil changes, the yoke assembly The yoke in the magnet will rotate the magnetic steel assembly, thereby pushing the push piece, so that the movable contact is separated from the static contact or closed. However, the ex...
