Mobile WebSiteDetection and judgment of the burnout of the electric wire harness
Burnout bunch of electric wires, all happen suddenly, and the burning rate is very fast, burn out the circuit, generally have no insurance device. Burn the law of the electric wire is: in the power system of the circuit, which point of access, where the wire bundle burned, burned and intact parts of the junction, it can be considered as the ground wire; if the wire bundle burn out To the wiring of an electrical equipment, it indicates that the electrical equipment failure.
Between the lines of short circuit, open circuit, poor contact detection and judgment
The wiring harness is subjected to external crushing and impact, causing damage to the wire insulation in the wire harness, resulting in a short circuit between the wires, causing some electrical equipment to run out of control and the fuse to blow.
Judgment, you can disconnect the electrical equipment and control switches at both ends of the electrical harness connector, meter or test light to detect short circuits.
Wire breakage fault, in addition to obvious fracture phenomenon, the common fault occurred in the wire and wire terminals between. Some wires open, the outer insulation and wire terminals intact, but the conductor wire and wire terminals have been broken. In the judgment, the conducting wire and the wire terminal suspected to be disconnected may be subjected to a tensile test. During the tensile test, if the insulating layer of the wire tapers, it can be confirmed that the wire has been disconnected.
Poor contact line, the fault occurred in the connector. When the fault occurs, it will cause the electrical equipment can not work properly. When judging, when the power of the electrical equipment is turned on, the relevant connector of the electrical equipment is touched or pulled and the work of the electrical equipment is suddenly abnormal and suddenly failed when a certain connector is touched, it indicates that the connector failure.
