Tunnel electronic manhole cover monitoring system

The intelligent manhole cover monitoring system uses the current advanced wireless communication technology, power supply technology, and sensor technology to incorporate the state of the manhole cover, the state of the underground environment, the opening of the manhole cover, and the inspection of the manhole cover into the unified maintenance management system, and establish the corresponding alarm processing Mechanism, the status of the manhole cover and the alarm content are displayed through the electronic map. If the manhole cover is stolen or damaged, the monitoring personnel can go to the scene to deal with it in time and quickly Resolve safety hazards. The system can realize the data collection, real-time display, diagnostic analysis, fault alarm of various security signals of the manhole cover, so that the dispatch center, operation and maintenance station, and management departments can intuitively understand and master the operation of the underground pipeline network

Maintenance-free intelligent transformer breather


The maintenance-free transformer breather is an air dehumidification and purification device used for oil-immersed transformers, instrument transformers, on-load tap changers, or other electrical equipment filled with insulating liquid. The maintenance-free transformer breather is installed at the air inlet of the instrument transformer's oil storage tank. When the transformer or instrument transformer operates, the oil volume changes due to temperature variations, causing the gas inside the oil storage tank to breathe through the desiccant. Air passes through the filter at the bottom of the desiccant and the glass jar filled with silica gel into the transformer, ensuring that the inhaled air is dry (moisture is adsorbed by the desiccant) and clean (dust and impurities are blocked by the filter), thereby maintaining the cleanliness and insulation strength of the transformer oil.

JC-OM700-EE Wireless Expansion Joint Sensor


The JC-OM700-EE wireless expansion joint sensor achieves online monitoring of expansion joint compensation by modifying the existing mechanical vernier caliper of GIS/GIL expansion joints or adding a digital expansion joint displacement sensor. The wireless expansion joint sensor uses a high-speed ARM chip as the main controller and a high-precision displacement sensor to sample and calculate the displacement data of the measured object in real time. It can upload data to the host computer via wireless LoRa and wired RS485.
