Overview
——————

 

 

The STBOM-800 series products are committed to solving the traditional problem of regular equipment maintenance, blind disassembly, and wastage of a large amount of manpower, material resources, and financial resources. At the same time, it also reduces power outage losses and improves the lifespan of a complete set of equipment. Based on intelligent sensors for online monitoring of primary equipment, various status data such as mechanical characteristics, opening and closing vibration characteristics, breaking current, and environmental parameters collected by the on-site sensor layer are analyzed to provide equipment health status discrimination, fault prediction, and optimal solutions, as well as equipment electrical life prediction. Provide data support for the maintenance and scientific management of primary equipment.
