Cable joint comprehensive monitoring program

Introduction

Cable status sensor is an intelligent sensor that combines high speed signal processing technology and micro power management technology to monitor partial discharge and surface temperature of distribution cable joints. It can be configured at the position of cable intermediate connector and terminal connector. The whole processing module of the sensor is encapsulated inside a sealed box. With IP rating higher than IP68, it can realize accurate detection in harsh environments such as high humidity and immersion. It can effectively monitor the power cable and reduce the probability of cable failure.

Characteristics

n Excellent performance, high accuracy and reliability

Support three-in-one multi-parameter comprehensive monitoring function of partial discharge, temperature and sound. It can effectively eliminate interference signals and accurately identify abnormal signals such as partial discharge, temperature and sound by virtue of high-speed parallel data processing technology as well as such techncial means as differential noise reduction, spectrum analysis, sound screen isolation, etc.

n Comprehensiveness

It is equipped with a variety of probes, which can monitor both cable intermediate joints and cable terminal joints; supports TEV sensor, temperature sensor, sound sensor, etc., and simultaneously detects weak insulation, poor contact and abnormal temperature near the installation point, providing multi-dimensional data support for judging operation status.

n Low power consumption

Low-power LoRa communication, advanced energy management methods and micro-power information processing technology; the configuration above makes the average detection power consumption of the equipment always under very low state; service life: 5 years.

n High IP rating

With a IP rating higher than IP69, the sensor can work better in environment with high humidity, mildew, etc. stably in the long run.

n Support multiple forms of applications; periodical detection and wireless uploading

It can be transmitted to remote monitoring master station remotely; operation and maintenance personnel can also check the data regularly near the ring network cabinet/cable well.

Applications

n Monitoring of cable termination joints in cabinets

Solve the problems such as the corresponding detection and maintenance difficulties of cable terminal joints in the cabinet, to avoid accidents caused by the damage of cable external insulation and joint loosening.

n Intermediate joint monitoring of underground cable

Detect cable operation defects accurately in real time and give out alarm information by multi-frequency mutual discrimination, differential noise reduction and high-speed parallel data processing technology in virtue of contact temperature measurement.

Wireless communication interfaces are embedded inside the sensor so that information can be easily accessed into the transmission layer.
