Electrical hot spot and fire monitoring of high-rise buildings

The high-voltage cable is the main line of the building power supply system, with large current and high heat generation. In addition, the high-voltage cable is in a closed state in a hard well, which is not easy to dissipate heat, and is prone to local overheating. If such abnormal temperature change can not be found in time, it will lead to cable insulation failure, and in serious cases, it will cause cable breakdown and sudden power failure, which will have an adverse impact on production and life in the building.

High voltage cables are distributed in every floor of the building. Once a fire occurs, it will endanger the life and property of the building. Dtv5.0 series distributed optical fiber temperature sensing fire detection system can monitor the temperature change of high-voltage cable in real time, so that managers can always understand the safety situation of the building.

System advantages:

1、It can accurately measure the temperature within the whole length range of high-voltage cable and shaft

2、Early detection and alarm of abnormal condition of high voltage cable

3、Three dimensional human-computer interaction interface, simple and intuitive, easy to operate

4、Two level constant temperature alarm can be set, with early warning of abnormal temperature rise

5、The optical fiber for temperature measurement is small and flexible, which can be installed in a narrow space, and can be installed and laid in the way of air blowing

6、Optical fiber is anti electromagnetic interference and can be directly installed on the outer surface of high-voltage cable

7、The optical fiber is protected by two layers of metal armor, which can resist the rodents' biting       

8、The system can accurately locate alarm points and fault points, and win time for equipment maintenance and emergency repair
