Cable vga cable connector and causes fever hazards, prevention and treatment

 We in the production, research and life in a variety of electrical equipment, are designed in accordance with certain requirements, connected by wires, lines inevitably there is a lot of electrical connectors and wire connectors. Electrical equipment inside the electrical connector at the factory usually undergo a rigorous inspection and test, but WISDOM VGA CABLE  also put into operation before the test is generally not a problem. The device external wire connectors, usually only found the problem through artificial inspections and checks in order, it is the weak link in the line. I have personally heard head office on the second floor of a research institute where the power switch at a copper and aluminum lugs and Capacity-conditioned dormitory on the third floor of the exclusive long-term recurrent fever lugs, black and emit a foul smelling odors taste and disgust already, resolve to study the heating wire connectors.
Electricity production, life process, due to equipment break wire connectors and other accidents caused by overheating, representing part of the overall electrical accidents, to secure supply, electricity tremendous threat must not be taken lightly. The reason, one is on duty is not strong sense of responsibility, inspections are not in place, the other is the lack of attention to a lot of workers wire connectors, check for hot spots tips and measures. Therefore, the emphasis of the project to install wire connectors to connect, learn to find joints, fever, joint fever prevention and treatment technique is very important.
1 wire connector fever phenomenon and its hazards
Wire connectors fever phenomenon, generally the first performance of the wire around the joint smell, can smell, which is due to the heating wire connectors make outsourcing an insulating layer odor; secondly, wire smoke joints, redness, outsourcing insulating layer black , get angry, or even break. Wire connectors will not only cause a lot of heat energy loss, but will seriously affect the normal operation of electrical equipment, ranging from the current line of work increases, shortening the life of electrical equipment, weight is suddenly interrupted the ongoing production, scientific research, medical surgery and other activities, but also lead to fire and WISDOM utp cable  electric shock, etc., resulting in incalculable losses.
2 wire connector fever causes.
Some construction workers in the electrical installation wiring, often do not pay attention to install Quality: insulating sleeve in place should not install casing; should be used where there is no junction box mounted junction box; even wire splice joints instead of using the method , instead of using illegal methods of hook-shaped connection. Contact resistance of such a large hook-shaped connection method, continuous heat when energized, causes the gradual drying of wood nearby, charring, and finally combustion occurs, causing a fire. Comprehensive analysis of the author may have several reasons: equipment installation, repair joints are not tightened, when the current through the heating may even redness, smoke, sparks, broken wires and switches, electrical connection via wire line column due to sloppy construction, the terminal without washers, gongs cap is not tightened, which also makes contact resistance increases, such as a hotel, the  WISDOM Displayport CABLE distribution box because of this reason, the resulting heat conductor melted bead Cardboard boxes below the falls, causing a fire; long-running joint will loosen some joints when installing quality is quite good, but due to thermal expansion and contraction of the reasons, or long subjected to vibration, causes loose joints, such as the long-term running aluminum joints, the contact surface is no silver or tin joints did not hang, because the contact surfaces have serious galvanic corrosion oxide film, so that the joints resistance increases, very easy to become hot spots; usually small current flowing through the contacts, due to a sudden change in the system, the current suddenly increases, resulting in the contact heating; system short-circuit fault occurs, so that an insufficient capacity overcurrent defective contact or contacts, the momentary sparkle like.
