Intelligent early warning device for SF6 gas content monitoring

Abstract

The invention discloses an intelligent early warning device for SF6 gas content monitoring. The device comprises a monitoring unit, a gas circulation unit and an intelligent acousto-optic speech earlywarning unit. The device is characterized in that the monitoring unit comprises an SF6 gas detection probe, an oxygen monitoring probe, a temperature and humidity transmitter and a monitoring controlmain control center; the SF6 gas detection probe and the oxygen monitoring probe adopt integrated double gas probes; the monitoring control main control center is divided into a factory monitoring host and a remote monitoring host; the gas circulation unit comprises a fan controller and a fan; and the intelligent acousto-optic speech early warning unit comprises a human body sensor and an acousto-optic alarm. The intelligent early warning device is designed for monitoring indoor SF6 gas content, can provide guarantee for the personal safety of on-site operators, can find and report problems at any time based on the accuracy and instantaneity of the device, and can facilitate the operators to solve the problems.

Description

technical field [0001] The invention relates to the safety field of harmful gas treatment, in particular to an intelligent early warning device for SF6 gas content monitoring. Background technique [0002] SF6 gas is a very stable halogen compound at room temperature. Its molecule is an octahedron composed of a sulfur atom and 6 fluorine atoms. It is not suitable for decomposition and ionization. It is colorless, odorless, non-toxic and non-corrosive under normal temperature and pressure, does not burn or support combustion in the air, does not react with water, strong alkali, ammonia, hydrochloric acid, sulfuric acid, etc., and has a density about 5 times that of air. Good chemical stability and thermal stability, excellent electrical insulation and arc extinguishing performance. However, under the action of arc, spark discharge and corona discharge, SF6 gas can decompose and release various products, mainly SF4 and SF2, and a small amount of S2, F2, S, F, etc. These toxi...

AI Technical Summary

Problems solved by technology

At present, the SF6 gas concentration online monitoring and alarm system used in the power system can only be displayed on the device control screen, and cannot realize the broadcast function; secondly, when the operator approaches, the operator cannot be more clearly reminded of the monitoring situation, which may cause SF6 People who are not familiar with the system characteristics enter the dangerous area rashly, and considering that the current alarm system cannot remind the staff of relevant safety precautions
