In the new era, as the process of industrialization continues to improve, the value-added of global industry continues to rise, with the rapid increase in industrial demand for electricity. At the same time, the increase in per capita living standards has greatly increased the demand for electricity. Therefore, how to ensure the normal supply of electricity has become an urgent problem to be solved in modern society. The failure rate of power facilities, whether the power maintenance personnel have a high-efficiency dispatching level, whether the timely maintenance of power facilities, etc. , have become an important factor affecting the normal power supply. After a large number of investigations, it is found that the fault caused by power cable is one of the main factors affecting the normal power supply. The main reason of cable fault is that the cable is in long-term operation, which will lead to partial discharge, temperature rise and other abnormal, and then lead to fault, affect the power supply. And power cable fault location, often located in the cable joints. If the power cable is effectively monitored, the probability of cable failure will be reduced. Haoyuan Huineng, as a provider of smart power solutions, combines high-speed signal processing technology with micro-power management technology, starting from the pain points of industry and users, an intelligent sensor for monitoring the status and surface temperature of distribution cable has been developed, which can be arranged in the position of intermediate and terminal joints of the cable. The whole processing module of the sensor is sealed in the sealed box, and the protection grade is better than IP68, which can ensure accurate detection in high humidity, water immersion and other harsh environments.
【Product features】
1. Excellent performance, high accuracy and reliability, with integrated multi-parameter monitoring function of partial discharge, temperature and sound, using high-speed parallel data processing technology, combined with differential noise reduction, spectrum analysis, sound screen isolation and other technical means, effectively eliminate interference signals, accurate identification of partial discharge, temperature, sound and other abnormal signals.
2. It is equipped with a variety of probes, which can be used to monitor both the cable intermediate joint and the cable terminal joint, and it has TEV, temperature, sound and other sensors, it can simultaneously detect the weak insulation, poor contact and temperature anomaly near the installation point, and provide multi-dimensional data support for judging the Operation State.
3. Low-power LoRa communication, combined with advanced energy management method and micro-power information processing technology, makes the average detection power consumption of the equipment in a very low state, and the service life of the equipment can be up to 5 years.
4. The high protection grade sensor is better than IP68. It is more suitable for long-term stable work in high humidity and mildewed environment.
5. supports a variety of applications, periodic detection, wireless upload can be sent to the remote monitoring station, but also by the operation and maintenance personnel in the ring cabinet/cable well near the regular data.
【Product advantages】
1. The advanced technology of partial discharge, temperature, sound function, periodic multi-parameter integrated monitoring cable joint operating environment, can be the sensor call, support single call and group call function.
2. Economic Benefit High and low cost, using plastic mold material, the overall protection grade is IP68.
3. The Low-power electronics is battery-powered, and the nodes are battery-compatible and can last up to five years.
4, practical strong product small size, small space can be installed, can cover all installation environment.
【Product applications】
1. For the monitoring of the cable terminal joints in the cabinet to solve the problems of the corresponding detection and maintenance of the cable terminal joints in the cabinet, etc. , avoid the occurrence of malignant accidents caused by the destruction of the external insulation of the cable and the looseness of the joints.
2. The monitoring of the middle joint of the cable running underground adopt the technology of multi-frequency mutual discrimination, differential noise reduction and high-speed parallel data processing, combined with contact temperature measurement, it can detect the defects of the cable and give the alarm information in real time.
A wireless communication interface is embedded in the sensor, allowing information to be easily connected to the transport layer.
