SF6 online monitoring system: prevention of oxygen deficiency and suffocation accidents caused by SF6 gas leakage-Instrument Network

With the vigorous and rapid development of the power industry, and the improvement of the level of technology and equipment in the power industry, SF6 electrical equipment has also been widely used. Technology is a double-edged sword. With the use of SF6 electrical equipment, the risk of SF6 gas leakage has also increased. SF6 gas is an inert gas that is colorless, odorless, odorless, non-toxic, and has a density heavier than air. If a leak occurs, SF6 gas will sink below the air, causing a large accumulation of SF6 gas in the lower space of the equipment and leading to oxygen deficiency and suffocation accidents.

On November 14, 2012, an oxygen deprivation and suffocation accident occurred at a steel plant in Anfi, Nevle department, central France, causing 2 deaths and 10 injuries.

The SF6 gas leakage monitoring and alarm system (LE-Mi2000) developed by our company is an intelligent online monitoring system designed and developed to provide personal health and safety protection for workers in distribution equipment rooms with SF6 equipment installed, based on the current emphasis on safety production in the power system.

The SF6 leakage online monitoring and alarm system (LE-Mi2000) is specifically designed for SF6 switch stations of various voltage levels in the power system. It is a comprehensive monitoring and alarm system that integrates the monitoring functions of SF6 concentration and oxygen content in the indoor environment of the switch station. The system has temperature and humidity online monitoring and fan linkage control functions.

The SF6 gas leakage monitoring and alarm system (LE-Mi2000) is a comprehensive organic equipment system that can be monitored on-site and dynamically synchronized on the main control room computer; Support remote alarms from the dispatch center through hard contacts with on-site remote control devices. And facing the overall design of SF6 switchgear, it is compatible with the access function of SF6 gas density micro water online monitoring.

LE-Mi2000 meets the four functional requirements for SF6 substation maintenance and management proposed by the SF6 industry safety regulations:

A. Oxygen deficiency and SF6 over limit alarm.

B. When the environment is abnormal, the ventilation function of the joint control fan is activated.

C. Local display and audible and visual alarm prompts at the entrance of the switch room.

D. Define any time period or forced ventilation function.
