Online sulfur hexafluoride gas leakage monitoring system based on differential absorption laser trolley

Abstract

The invention discloses an online sulfur hexafluoride gas leakage monitoring system based on a differential absorption laser trolley. The online sulfur hexafluoride gas leakage monitoring system based on the differential absorption laser trolley comprises the differential absorption laser trolley, a GPS (Global Position System) satellite, a wireless base station, a processing platform and a smart phone, wherein the processing platform gives an instruction to command the trolley to detect a leakage concentration value and a leakage point position of SF6 gas, the trolley transmits the detected data to the processing platform, the processing platform calculates the leakage concentration value and the leakage point position of the SF6 gas and the trolley position information and displays the information on an electronic display screen; and when the leakage concentration exceeds a certain value, the indicator light flickers, the buzzer rings, and the alarm aim is achieved. Meanwhile, the processing platform transmits the calculated leakage concentration value and the leakage point position of the SF6 gas and the trolley position information to the mobile phone in a short message form. The online sulfur hexafluoride gas leakage monitoring system disclosed by the invention has the functions of SF6 gas leakage detection, high accuracy positioning, wireless communication and the like.

Description

technical field [0001] The present invention relates to SF 6 The field of gas leakage detection, more specifically, relates to an online monitoring system for sulfur hexafluoride gas leakage based on a differential absorption laser car. Background technique [0002] With the continuous improvement of people's living standards, electric energy has become an indispensable part of daily life, and people's requirements for electric energy are getting higher and higher. Uninterruptible power supply is also one of the important factors to measure the quality of electric energy. in SF 6 The closed combined electrical equipment (GIS) equipment with gas as the insulating medium is widely used in power plants, SF 6 Gas leakage affects the normal operation of power equipment, resulting in a serious greenhouse effect, and SF 6 Gas is relatively expensive, and large leaks can cause major financial losses. Therefore, the SF based on the differential absorption laser car 6 The gas lea...
