Temperature Monitoring Sensor System for Rail Transit Transformer Winding

Rail transit fiber optic temperature controllers are specially customized for power supply transformers in rail transit systems, utilizing fluorescent optical fiber temperature sensors independently developed by our company as the temperature sensing element. The fiber optic probe demonstrates immunity to electromagnetic interference and high voltage resistance, with its superior characteristics fundamentally eliminating interference from input channels to the temperature controller. Currently, this solution has been extensively deployed in multiple rail transit projects across China, including Guangzhou Metro, Shenzhen Metro, and Xiamen Metro systems.
