Research On Standby Power Switching Technology And Solenoid Valve Tester Of Esd System In Gas Transmission Station

As the country and society pay more and more attention to the safe production of natural gas,the safe and stable operation of gas transmission station is crucial to the stable and sustainable development of natural gas industry.ESD system,as an emergency protection system of the station in the process of long-distance transport pipeline,plays an irreplaceable role in ensuring the smooth operation of long-distance transport pipeline.It is the last barrier for station operation,and an important means to reduce accident disasters and complete on-site emergency treatment.Therefore,this paper mainly studies the dc voltage test system of ESD in gas transmission station and the seamless switch technology of backup power supply for development and transformation.This article first summarized the gas station of ESD system current situation of research at home and abroad,and analyzes its working principle,has been clear about the current gas station of ESD system basic working principle,structure,analysis of the current gas management office,the application of ESD system in-depth analysis of the role of various components of gas transmission station ESD system,collects and analyses the current present situation of the application of ESD system in the power supply part,get the power supply of gas station ESD system modification can implement part,conclusion.Second for gas service station of the operation situation of ESD system is analyzed,including the gas service gas station using ESD system and the problem of statistics,is proposed to design a ESD system electromagnetic valve dc voltage tester is installed in place of ESD system electromagnetic valve actuator and the ESD system running status real-time monitoring,ESD system recessive operation be made explicit,also facilitate the station staff on duty on the ESD system for routine inspection and monitoring,as well as areas in the ESD system provides reliable field data of the running and maintenance work.The optimization of power supply system and technical improvement are particularly necessary.Next,the research and development and transformation plan of ESD system in gas transmission station is conducted from the perspective of dc voltage test system and the seamless switch technology of backup power supply.After field test and analysis of operation,it can be concluded that the technical transformation plan of ESD system in gas transmission station is effective and feasible.After field test and trial operation,the pre-designed target has been achieved,which can be effectively applied in field practice,has high reliability,and can effectively guarantee the safe and stable operation of gas transmission station.
