Product Overview:
SF6 leakage alarm online monitoring system is an online monitoring and alarm system for SF6 insulation gas leakage of indoor SF6 combined electrical equipment in a new unmanned substation. The system can measure SF6 leakage gas content quantitatively and online in real time, with high measurement accuracy, remote data transmission and easy installation and use. The system can carry out multi-point monitoring of indoor SF6, oxygen concentration, ambient temperature and humidity, with up to 128 monitoring points.
Features:
● This system uses NDIR sensor. The infrared sensor has the characteristics of long life, stable and reliable operation, non-contact, little environmental influence and strong anti-interference.
● The system for SF6 and oxygen double detection, more effectively to ensure the safety of staff working environment.
● Field bus design, convenient user and all kinds of system communication, seamless connection.
● All data can be stored continuously for one year for reference and curve analysis.
● Support voice broadcast scene situation, staff can get voice prompt before approaching dangerous environment without operation.
● After the site data is uploaded to the cloud platform, it can be viewed by multiple computer terminals and mobile terminals.
