MSDGCD series low voltage cabinet fluorescent optical fiber temperature monitoring system

A variety of power supply and control lines in the low-voltage drawer cabinet are arranged in a relatively narrow space, so that the heat is gathered and should not be dissipated, causing the temperature to rise. Excessive temperature will cause the current carrying capacity of the circuit breaker to decrease, which is different from the actual setting value, which is easy to cause the circuit breaker protection trip. The fluorescent optical fiber temperature sensor is a temperature measurement technology based on optical signals. The sensor has no conductor structure, is insulated and resistant to electromagnetic interference, and has a small size and a long life. It is very suitable for direct measurement of hot spots of connectors in this scenario.
