SF6The gas leakage quantitative alarm system is designed to address the current situation of emphasizing safety production in the power system, and is installed forSF6An intelligent online detection system designed and developed to provide personal health and safety protection for the staff in the power distribution equipment room of the equipment.

The system mainly detects in the ambient airSF6Gas content and oxygen content, when in the environmentSF6If the gas content exceeds the standard or there is a lack of oxygen, an alarm can be triggered in real time, and the ventilation system can be automatically turned on. It also has many rich functions such as temperature and humidity detection, voice prompts for working status, remote alarm, and historical data query.

Product Features

l Select advanced high-sensitivity imported sensors with long lifespan and equipped with false alarm filtering software to avoid false alarms.

l Micro monitoring technology can issue early on-site alerts, indicate the location of gas leaks, promptly notify personnel in hazardous areas to evacuate, search for and eliminate leakage sources, and protect operating equipment.

l One cable connectionSF6/O2Transmitter, infrared, host, fan controller, can be separated or combined, with high on-site adaptability.

l Multi point simultaneous monitoring to meet the needs of the on-site environment and improve monitoring reliability.

l Can be achieved throughRS485perhapsRS232The bus transmits data remotely to the remote control center, which can also directly query and control the monitoring system remotely.

l Carefully designed high-frequency low current high voltage switching power supply, applied toSF6The sensor monitoring head has the characteristics of safety, reliability, and high efficiency. Fully utilize the flexibility of microcontrollers.

l 85V～265V ACMeet the needs of different on-site environments.

l Large LCD color display screen, beautiful and elegant, with clear operation status at a glance. Simple operation interface, easy to operate

l The large capacity storage provided by the system host can store historical data for more than a year, and the high-performance query system software ensures that the system can quickly query historical data within seconds.
