Performance of Li Xia n5 Throttle Relay Fault What is the reason why relay contacts are not in contact?

1. Contact pair adhesion: Contact pair adhesion of relay contacts is usually caused by contact fusion welding, mostly due to improper use, improper installation, heavy load or too frequent operation. 2. Unstable contact: When the relay is used for a long time, defects and burrs appear on the contact surface due to oxidation or arc ablation, which increases the contact resistance of the moving and static contacts, resulting in excessive temperature rise of the contacts, and the surface contact becomes point contact, or even non-conduction in severe cases. 3. Poor contact caused by deformation of contact bridge: Poor contact of relay caused by deformation of contact bridge, deformation of elastic connector or change of elastic coefficient. 4. When the relay is engaged and disengaged, the arc causes the contact to wear too fast: When the relay is engaged and disengaged, the arc causes the liquid bridge or metal to transfer, which leads to the contact to wear too fast and reduces the service life of the relay.
