In view of the hidden danger of blockage of substation cable trench and station building drainage, a real-time detection system is developed to detect whether the cable floor of substation and other places are flooded due to water leakage and rain.
The product adopts ultra-low power consumption design, radio frequency communication, CRC calibration and other technologies. It is green, maintenance free, complete electrical isolation, convenient installation, strong anti-interference ability, reliable operation, compact size and other characteristics, which can solve the problem of water immersion very well. The acquired water immersion signal is transmitted to the monitoring terminal through RF communication in real time to realize uninterrupted and accurate alarm.
This product uses the 2.4GHz LoRa wireless communication technology platform, and the communication protocol uses the Internet of Things micro power wireless network communication protocol of the State Grid power transmission and transformation equipment to achieve dual-way communication, intelligent management of power equipment operation monitoring, and provide data support for the safe operation of power grid equipment.
Application field: cable trench in substation and other places that may be immersed in water.
