Low-voltage power supply line wire connection part temperature sensing monitoring and early warning system

Abstract

The invention discloses a low-voltage power supply line wire connecting part temperature sensing monitoring and early warning system, which comprises a temperature sensing color-changing electrical insulating tape wound on a low-voltage power supply line wire connecting part, an image acquisition device for acquiring images of the temperature sensitive color-changing electrical insulating tape, awireless communication module and a remote monitoring terminal, the temperature-sensitive color-changing electrical insulating tape changes color when the temperature of the connecting part of the low-voltage power supply line wire exceeds an early-warning threshold value, the image acquisition device transmits an acquired temperature-sensitive color-changing electrical insulating tape image to the remote monitoring terminal through the wireless communication module, and the remote monitoring terminal is provided with a display screen and a temperature-sensitive early-warning module. When color change of the temperature-sensitive discoloration electrician insulating tape is detected, early warning information can be sent out. Therefore, measures can be taken in advance to reduce fire hazards and equipment damage risks caused by wire burnout after heating, troubleshooting time can be remarkably shortened, and maintenance cost is reduced.

Description

technical field [0001] The invention belongs to the technical field of electric engineering, and in particular relates to the safety monitoring technology of the connection part of the lead wire of a low-voltage power supply line. Background technique [0002] In low-voltage electrical technology, the role of insulating tape is very important. It is inevitable that low-voltage power supply lines need to be connected. After stripping the original metal sheath of the wire, it must be covered with insulating tape to maintain the insulation performance of the connected part and avoid electric leakage and electric shock to humans and animals. However, in practical applications, we found that the connecting part of the two wires is also the part with a high frequency of various faults in the low-voltage line, mainly manifested in the abnormal heating of the connecting point due to water ingress, oxidation, loosening and other reasons at the connecting position until the final burno...

However, in practical applications, we found that the connecting part of the two wires is also the part with a high frequency of various faults in the low-voltage line, mainly manifested in the abnormal heating of the connecting point due to water ingress, oxidation, loosening and other reasons at the connecting position until the final burnout. Due to the current non-transparent design of electrical insulating tape, the situation inside the connection point cannot be observed or even if it can be observed, the state cannot be effectively judged, which seriously affects the normal operation and troubleshooting of the equipment
