It adopts high-frequency real-time sampling technology, which can monitor parameters such as insulation resistance and leakage current of cables in real time. Once abnormalities occur, it can trigger multi-level alarms. It supports 4G/NB-IoT wireless communication, which can synchronize monitoring data to the cloud operation and maintenance platform, and the cable operating status can be viewed remotely without on-duty duty. It adopts a stainless steel sealed shell with IP66 protection grade, which can adapt to extreme temperatures and harsh working conditions outdoors. It supports two installation methods of wall-mounted and pole-mounted, adapting to different cable operation and maintenance scenarios. Unlimited cloud storage can store historical monitoring data, and supports generating monthly and quarterly operation and maintenance reports to help the operation and maintenance team optimize the inspection plan.
A single set of equipment can monitor a range of 0-100km, with a fault detection accuracy of ±0.5%, a sampling frequency of 1000Hz, and a power supply mode of AC 110V/220V. The working temperature range is -40℃ to +70℃. It adopts a 304 stainless steel sealed shell with an IP66 protection grade, supports two installation methods of wall-mounted and pole-mounted. It is equipped with 4G/NB-IoT wireless communication module, supports three alarm methods of App push, SMS and email, uses unlimited cloud storage for data storage, and supports multi-account permission management, adapting to the collaborative work needs of large power operation and maintenance teams.
It is suitable for online monitoring of ultra-long distance transmission cables, submarine cables, and cables in urban underground utility tunnels. It can be used as a long-term operation and maintenance monitoring device for large power enterprises, and can master the operating status of cables in real time, detect fault hazards such as insulation aging and local overheating in advance, avoid power outages caused by sudden faults, and adapt to the digital transformation needs of smart grids.
