In daily life, it is inevitable that the connectors of new energy electric vehicles will be damaged, which will cause unnecessary trouble. Therefore, we protect during use, so what are the factors that cause damage to the electrical connector? Today, the electronic engineer of Elecbee is here to explain the content related to this.
Reasons for damage:
- The electric connection wire or the wire clamp is not enough current to be burnt or broken.
- The electrical connection cable is seriously broken, and the strands or wires are burned.
- The electrical connection wire is corroded seriously, causing the cross-sectional flow surface to be insufficient and the strand or wire is burnt.
- Poor contact between the electrical connection line and the wire clamp or poor contact between the power supply line clamp and the contact wire, causing burns.
- The current-carrying surface of the wire clamp and the lead is not contacted enough, causing burning.
- A certain place where the clamp nut is loose is not found and treated in time, causing the electrical connector to fall off.
- After installation of the new energy electric vehicle connector, there is no temperature change offset reserved or the offset reserved too little.
- After the electrical connector is installed, the reserved value of the temperature change offset is large, and the vertical electrical connection line between the load-bearing cable and the contact line relaxes until it relaxes to the lower part of the contact line and is hit by the pantograph in operation. Broken or cut off. The distance between the bottom ring of the vertical part and the contact line is too small, and it is damaged by the pantograph.
- The skewed installation of the power supply clamp on the contact wire was knocked out by the pantograph, which caused a bow-cutting accident.
- If the catenary is cut at other positions, the pantograph continues to run to the place where the electrical connector is installed, and the electrical connector is broken.
The above is the reason for the damage of the electrical connector shared by the electronic engineer of Elecbee. Knowing these, as long as we do a good job of protection during use, the service life of the connector will become longer.
