Product Description
System features
LHRZCW22 type transformer winding optical fiber temperature control system uses fluorescent temperature measurement technology, the fluorescent fiber sensing probe is directly installed in the transformer temperature measurement, can real-time, safe and accurate measurement of transformer winding temperature, to achieve a comprehensive monitoring of the internal temperature of the transformer, in order to make accurate judgments and decisions, so as to extend the service life of the transformer equipment.
Functional features
◎ Reliable, economical and effective monitoring of the real temperature of transformer oil: Different from the traditional way of measuring the temperature of the bottom or top oil, the optical fiber temperature measuring probe is arranged at the winding of the oil-immersed transformer to monitor the hottest temperature of the oil.
◎ No oil leakage of optical fiber installation, anti-electromagnetic interference ability.
Fiber optic sensing probe sensor is made of chemically inert rare earth materials, which can be used safely in almost any environment, free from EMI, RF, MRI and microwave interference, with small size, high temperature measurement accuracy, fast response time, stable performance and other characteristics.
◎ With RS485, dry contact, 4-20mA and other signal interfaces.
system composition
LHRZCW22 type transformer winding optical fiber temperature control system is mainly composed of optical fiber sensing probe, flange, external transfer optical fiber, optical fiber temperature controller.
