It adopts non-contact electromagnetic induction sampling technology, and can complete monitoring without powering off the cable line, avoiding the cost and inconvenience of power outage operation required by traditional offline detection. The IP65 protection grade is suitable for complex outdoor environments such as high temperature, low temperature and heavy rain, and the fully sealed metal shell has good corrosion resistance and anti-interference ability. It supports multiple communication methods such as 4G/NB-IoT and Ethernet, can be adapted to different scales of power grid operation and maintenance systems, and the cloud platform supports unified management of multiple devices, which can generate cable insulation performance trend reports and predict fault risks in advance. It is equipped with a solar backup power module, which can still maintain basic monitoring functions when the mains power is interrupted, ensuring the continuity of monitoring data.
The is 220mm×180mm×100mm, with a net weight of 3.5kg, supporting two installation methods: wall-mounted and pole-mounted. The monitoring voltage covers 6kV to 35kV high-voltage cables, the insulation resistance monitoring range is 1MΩ to 1000GΩ, and the sampling frequency can be adjusted from 1 time per minute to 1 time per hour. It is equipped with 32GB local SD card storage and cloud data backup functions, supports custom alarm thresholds and alarm methods (SMS/APP push). The power supply adopts AC220V mains power + 10W solar panel backup scheme, the working temperature range is -40℃ to 70℃, complying with IEC 61850 power communication standards and GB/T 12706 cable testing standards.
It is mainly used for real-time monitoring of insulation status of urban underground high-voltage cable corridors, overhead high-voltage transmission lines and wind power collection lines; remote operation and maintenance of high-voltage power supply lines in industrial parks; centralized management of cable insulation in power dispatching centers; and cable safety monitoring of railway traction power supply systems, providing 7×24-hour automated insulation monitoring services for power operation and maintenance enterprises, reducing the cost and risk of manual inspection.
