A cable joint temperature measuring device

Abstract

The invention discloses a cable joint temperature measuring device. It includes a temperature measuring sensor, a temperature measuring sending device, and a temperature measuring receiving device. The temperature measuring sensor is set on the grounding part of the outer conductive layer of the cable joint or the temperature measuring sensor is set on the cable inside the cable joint. The temperature measuring sending device and the temperature measuring receiving device There is an optical fiber connection between them; the temperature measurement sensor is used to measure the temperature parameter of the cable joint; the temperature measurement sending device is used to obtain the temperature parameter, and the temperature parameter is converted into an optical signal and sent to the temperature measurement receiving device through the optical fiber; the temperature measurement receiving device is used for Receive the light signal, convert the light signal into a temperature value for display, and give an alarm when the temperature value exceeds the preset value. The cable joint temperature measuring device provided by the embodiment of the present invention facilitates accurate and real-time detection of the temperature of the cable joint through the position of the temperature measuring sensor. The temperature measuring sending device and the temperature measuring receiving device are connected by optical fibers, which facilitates the transmission of the temperature of the cable joint .

AI Technical Summary

Benefits of technology

This patented technology helps detect accurately when there are high temperatures on an electrical wire used for communication purposes during installation or maintenance work without causing damage.

Problems solved by technology

This patented method solves issues related to insufficient monitoring and detection of high voltage (HV) cables' safe operating conditions through advanced sensors such as thermal fuses and optic fibers. However, these systems require accurate measurements from multiple points along their length before they fail because any errors could lead to catastrophic events like fires or explosions.
