Description

Technical Field

[0001] The present invention relates to a cable overheat detection device, in particular to a cable overheat array detection device. Background Art

[0002] It is known that cables will experience local heating after long-term use. Common cable overheating is concentrated in some old cables. At present, the main reason for cable overheating is overload. When the number of electrical devices connected in the circuit is large and the power is large, it will exceed the rated current that the cable can withstand, causing the cable to overload and overheat; circuit short circuit is also one of the common causes of cable overheating. Short circuit will cause a sudden increase in current. The cable cannot withstand excessive current and overloads and overheats; when the contact is poor, if the fastening nuts and wiring terminals of the cable connection terminals are not tightened firmly, the cable will have poor contact, which will increase the impedance when the current passes through the cable and cause local overheating at these contact points, which may cause fire over time; the cables are arranged too much Dense, poor ventilation and heat dissipation, or cables close to other heat sources, affecting normal heat dissipation is also one of the problems; the cable conductor resistance does not meet the requirements, the cable will generate heat during operation, because the resistance does not meet the requirements, it will cause heat when current passes through; the joint manufacturing technology is not good, the joint crimping is not tight, resulting in excessive contact resistance, causing the cable to heat up; the armored cable sheath is damaged, the sheath is partially damaged and water enters, the insulation performance is destroyed, the insulation resistance gradually decreases, causing the cable to heat up during operation; for the cable overheating problem, if the cause is not found and the fault is eliminated in time, the cable continues to be energized and operated continuously, which will cause insulation thermal breakdown after overheating, thereby causing the cable to short-circuit and trip, which may cause severe fire.
