The safety instrumented system is a system that is independent of the petrochemical production process control system and can independently complete the safety interlock protection function. It can avoid significant hazards to production equipment caused by process production failures, field instrument failures, system power supply failures, etc., and ensure safe operation of production equipment. In petrochemical plants, it is imperative to configure a safe, reliable, and timely safety instrumented system. Combined with applying the burner management system of the heating furnace in a refinery, the paper focuses on the technical realization of the hardware structure, system configuration, logic programming, man-machine interface configuration system debugging of the TRICON system. Practical application shows that TRICON?s safety instrumented system is a set of safety instrumented systems with comprehensive functions, safety and reliability, and easy to learn.

Service Inspection

After pressure equipment (aka fixed or static equipment) is designed, fabricated, and constructed to ASME new construction codes and standards (C/S), it is delivered and placed in-service. After that the In-service Inspection (ISI) and Post-Construction C/S begin to govern. Within the ASME, the Post Construction Committee (PCC) produces and maintains the standards that govern equipment after it has been placed inservice. Within the API Standards Organization, the Subcommittee on Inspection (SCI) and the Corrosion and Materials Subcommittee (CMSC) produce and maintain most of the ISI standards and recommended practices that govern pressure equipment in the refining and chemical process industry. This paper shows how many of those ISI and PCC C/S are intended to work together to maintain the safety and reliability of pressure equipment and piping after it has been placed in service. This paper also highlights what’s new with many of these C/S that have been recently updated or newly published. Both the API and ASME use the rigorous, standardized consensus building process outlined by the American National Standards Institute (ANSI) for formulating and publishing their respective C/S. This paper will show how users of these ISI/PCC codes and standards are benefited by the application of the ANSI consensus process.

Abstract As a necessary electrical equipment for the construction of power grid, the safety and reliability of the transformer is the focus that people have always paid attention to. In recent years, the DC bias of the transformer has a serious impact on the safe operation of the power system, which has attracted wide attention of scholars at home and abroad. In view of this phenomenon, combined with the basic principle of transformer excitation, the simulation of the DC bias phenomenon is carried out by using Simulink software in this paper. According to the simulation results, the distortion characteristics of excitation current under DC bias are summarized. Then, based on the variation characteristics of excitation current under over excitation and DC bias, the law of transformer core vibration is deduced, and the cause of transformer abnormal vibration under DC bias is revealed. Finally, by analyzing the data of a transformer substation running under DC bias, it is found that the measured data are basically the same with our simulation results, which provides a basis and reference for further research on the phenomenon of transformer DC bias.

A new refining technique was innovatively improved and a series of high-performance transformer oil was successfully developed from non-cyclic alkyl crude oil through hydrocracking, isodewaxing, hydrorefining and proportioning. And it breaks through a barrier that the traditional refining technology was restricted by the type of crude oil. The functional properties, refining and stability, performance in service, health, safety and environment properties of hydrogenated transformer oil were studied comprehensively and deeply under the static and dynamic condition, especially at the level of molecular structure. The safety and reliability of hydrogenated transformer oil in the power transformer has been proven scientifically. In order to further verify the reliability of hydrogenated transformer oil in power transformers, the 110 kV #3 main transformer with hydrogenated transformer oil in Dongguan Power Supply Bureau started to carry load to operate in December, 2011. The transformer has been being regularly monitoring and it has been operating in the good condition. And the research results have been converted into practical application successfully.

500kV Hainan Grid Connection project is the major project connecting Hainan Power Grid to Main China southern power grid. Submarine cable segment is a core part of the whole project. The safety and reliability of the whole project is directly determined by the situation of its main insulation. The submarine cable is affected by a variety of factors in the sectors of manufacturing, transportation and installation. Field voltage withstand test on the submarine cable is of great significance in order to check its insulation condition after installation. In this paper, field DC voltage withstand test of 500kV oil-filled submarine cable is researched. The data obtained in field trials is analyzed to evaluate the main insulation reliability. The results show that the manufacturing quality and the insulation condition installation after laying on site of the submarine cable is reliable, meeting the engineering requirements of safe operation.
