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.
