JC-OM200 Lightning Arrester Online Monitoring System

The JC-OM200 arrester online monitoring device realizes the monitoring of the insulation performance of the metal zinc oxide arrester. The online monitoring of the arrester requires two devices: the JC-OM200 arrester online monitoring device and the JC-OM200/PT bus voltage online monitoring device, which can monitor the full current of the arrester in real time. , Resistive current, capacitive current, number of lightning strikes, lightning strike time, through analysis and fitting processing of the monitored data, combined with the on-site working conditions, the leakage current of the porcelain sleeve caused by the pollution or internal moisture of the arrester can be found in time Or increase the leakage current of the insulating rod to avoid accidents.

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.
