Industrial Equipment Harness Processing Frequently Asked Questions

1. Faults of wiring harness processing joints of industrial equipment Accidents caused by non-standard terminal joints of various equipment joints are common. The reason is that many installers are not careful about the quality of installation when installing wiring harnesses. They do not install bushings where insulating bushings should be used, and do not install junction boxes where junction boxes should be used. As a result, the interface is hot and feverish when electrified, and then the surrounding areas are gradually dried and carbonized. There are many connection points on the wire harness, such as the wire and the switch, the wire and the wiring pile head of the electrical appliance, the connection point of the shelter device of the wire, etc. These joints are different from other parts of the wire. When the insulation layer at the joint is peeled off, if the wrapping cloth is not wrapped well, the two wires will collide with each other, which is likely to cause short circuit. Fever or spark. Second, industrial equipment wiring harness processing touches the wire fault, the wire generally has insulation shelter, as long as the insulation is not destroyed, although the two wires touch each other, it will not cause problems. Third, industrial equipment wiring harness processing joints are loose, some joints are of good quality when installed, but due to thermal expansion and contraction, or long-term vibration. It will make the joints loose, such as the electrical lines in the bridgehead of a bridge, because when the vehicle crosses the bridge, it often produces violent vibration, which makes the joints of the wires loose slowly, the contact resistance increases slowly, and the fever becomes more and more serious. Conductors are prone to form a layer of oxide (copper oxide is shown on copper conductors, and aluminum oxide is more likely to be formed on aluminum conductors). The motor performance of this kind of hydride is very poor. 5. Dust contaminates the soil. Dust infiltrates into the connection points of conductors, interferes with the contact between conductors, and causes overheating at the connection points. Solutions to the short circuit problem of industrial equipment wiring harness processing: (1) Turn off the power supply immediately. Track the source of the corresponding batch of equipment (2) let the engineer and the engineer of the wire processing factory carry out the defect analysis (3) use some professional equipment to search (4) record the relevant data (5) formulate the inspection and maintenance plan
