Undertake OEM/ODM services for OEM and OEM processing
Fuzhou Yingnuo Electronic Technology Co., Ltd. has independently developed an oil temperature oil level oil pressure three in one monitoring device based on the requirements of intelligent distribution transformers, combined substations for online monitoring, and related technical standards. It has the advantages of high safety, low cost, good real-time performance, convenient installation, and easy maintenance,
It can be used for oil immersed transformers and combined substations, providing a good solution for online monitoring of oil temperature, oil level, and oil pressure of power equipment.
The monitoring device can achieve precise monitoring of transformer oil temperature oil level oil pressure and upload it to the intelligent fusion terminal in the substation area through RS-485.
