No full textTransformatorske stanice su dio sustava za prijenos električne energije, a zadatak im je transformacija napona sa više naponske razine na nižu ili obrnuto, uz prijenos snage uz minimalne gubitke. Potreba suvremenog društva za potrošnjom električne energije neprestano raste, a posljedično raste opasnost od nastanka požara i eksplozija na električnim postrojenjima, instalacijama i opremi. Požarne te eksplozivne opasnosti mogu nastati kao posljedica zastarjelosti uređaja i opreme, opterećenja, grmljavine i drugih vremenskih nepogoda, mehaničkog oštećenja instalacija uslijed prisutnosti raznih glodavaca i slično. Prilikom projektiranja objekta, izrađuje se i procjena ugroženosti od požara koja dalje smjernice za gašenje požara te protokole postupanja. Pravilan izbor i ugradnja sustava za detekciju i gašenje požara, uz adekvatna konstrukcijska i tehnološka rješenja protupožarne zaštite temelj su sigurnosti u slučaju nastanka požara, a zadatak je sustava da isti lokaliziraju i spriječe njegovo daljnje širenje u što kraćem vremenskom razdoblju. Ovaj rad donosi pregled požarnih i eksplozivnih opasnosti, potencijalnih kvarova te uzroka požara i eksplozija kao i specifičnosti procesa gašenja požara na TS Dubovac 110/10/10 kV, kao i potencijalnih propusta te unapređenja djelovanja u procesu gašenja požara na takvom objektu. Osobit je naglasak pri pisanju rada stavljen na stečeno iskustvo samog autora rada u djelatnosti gašenja požara na visokonaponskim objektima. Važno je naglasiti kako gašenje požara na trafostanicama uključuje uvijek suradnju te koordiniranu aktivnost vatrogasnih postrojbi te nadležne ispostave poduzeća HEP, Ministarstva unutarnjih poslova te pripadnika Državne uprave za zaštitu i spašavanje. Suradnja je važna za brzo te efikasno gašenje požara na takvim objektima, ali i spašavanje ljudskih života koje je neizostavan dio gotovo svake vatrogasne intervencije.

The need of modern society for electricity consumption is constantly growing, and consequently the risk of fires and explosions on electrical plants, installations and equipment is growing. Fire and explosive hazards can occur as a result of obsolescence of devices and equipment, loads, thunder and other weather disasters, mechanical damage to installations due to the presence of various rodents and the like. When designing the facility, a fire risk assessment is made, which further guidelines for firefighting and treatment protocols. Proper selection and installation of fire detection and extinguishing systems, with adequate construction and technological solutions for fire protection are the basis of safety in case of fire, and the task of the system is to localize and prevent its further spread in the shortest possible time. This paper provides an overview of fire and explosive hazards, potential failures and causes of fires and explosions as well as the specifics of the firefighting process at TS Dubovac 110/10/10 kV, as well as potential failures and improvements in the firefighting process at such facility. Particular emphasis in writing the paper is placed on the experience gained by the author of the work in the field of firefighting in high-voltage buildings. It is important to emphasize that firefighting at substations always includes cooperation and coordinated activity of fire brigades and the competent branch office of HEP, the Ministry of the Interior and members of the State Administration for Protection and Rescue. Cooperation is important for quick and efficient firefighting in such facilities, but also saving human lives, which is an integral part of almost every firefighting intervention. Cooperation is based on actions in accordance with applicable legal regulations and bylaws in the territory of the Republic of Croatia
Substrate Effects on the Micro/Nanomechanical Properties of TiN Coatings
No full textNanoindentation and nanoscratch tests were performed for titanium nitride (TiN) coatings on different tool steel substrates to investigate the indentation/scratch induced deformation behavior of the coatings and the adhesion of the coating–substrate interfaces and their tribological property. In this work, TiN coatings with a thickness of about 500 nm were grown on GT35, 9Cr18 and 40CrNiMo steels using vacuum magnetic-filtering arc plasma deposition. In the nanoindentation tests, the hardness and modulus curves for TiN/GT35 reduced the slowest around the film thickness 500 nm with the increase of indentation depth, followed by TiN/9Cr18 and TiN/40CrNiMo. Improving adhesion properties of coating and substrate can decrease the differences of internal stress field. The scratch tests showed that the scratch response was controlled by plastic deformation in the substrate. The substrate plays an important role in determining the mechanical properties and wear resistance of such coatings. TiN/GT35 exhibited the best load-carrying capacity and scratch/wear resistance. As a consequence, GT35 is the best substrate for TiN coatings of the substrate materials tested
INTELLEGENT SYSTEMS FOR EARLY DETECTION OF FIRE IN OPEN SPACES: APPLICATION OF THE STRIBOR SYSTEM
No full textPožari otvorenog prostora predstavljaju ozbiljnu prijetnju eko sustavu, infrastrukturi i ljudskim životima. Posljednjih su desetljeća požari otvorenih prostora u stalnom porastu diljem svijeta i predstavljaju temeljnu ugrozu za kulturna dobra i šumske površine. Osim preventivnih mjera zaštite od požara jedini efikasni način smanjenja štete uslijed požara otvorenog prostora je pravovremeno uočavanje požara, brza reakcija i sprečavanje širenja požara što omogućuje implementacija inteligentnih sustava za ranu detekciju požara u vatrogastvu. Predmet rada su inteligentni sustavi za ranu detekciju požara otvorenih prostora, dok je cilj rada prikazati važnost implementacije inteligentnih sustava za ranu detekciju požara otvorenih prostora i dijelove tog sustava.Open space fire pose a serious treat to the ecosystem, infrastructure and human lives. In recent decades, fire in open spaces have been constantly increasing all over the world and represent a fundamental treat to cultural assets and forest areas. In addition to preventive fire protection measures, the only effective way to reduce the demage caused by fires in open spaces is timely detection of fires, quick reaction and prevention of fire spread, which is made possible by the implementation of intelligent systems for early fire detection in the fire department. The subject of the work is intelligent systems for the early detection of fires in open spaces, while the aim of the paper is to show the importants of the implementation of intelligent system for the early detection of fires in open spaces and the of that system
Thermal Actuation of Phase Change Tin Pump
No full textPressurized liquid Tin finds application in the generation of Extreme Ultra-Violet light for semiconductor lithography. In order to improve the throughput of the lithography systems, tin must be pressurized to higher levels, and in turn, new pressurization methods are needed.A phase change tin pump is an innovative system that pressurizes and pumps liquid Tin by harnessing the expansion and contraction during phase changes, without the need for any moving parts. The pump needs to pressurize liquid tin up to 2000 bars, with a pumping capacity of 4 ml/hr. Since this system relies heavily on control over the temperatures of tin, this study is set up to address the thermal constraints in the system by investigating three aspects of temperature distribution in the system.Firstly, the heaters in the pump are placed at discrete locations, but the working volume is continuous. Thus, it is challenging to define a temperature control function that can facilitate uniform melting and continuous flow of tin. The relation between rate of heat input to the pump and the rate of heat transfer in tin is estimated using an analytical model. From the analytical model, it is found that heating rates of the order of 0.1 K/s are required in order to melt tin in a reasonably uniform fashion over a zone length of 5 mm.Secondly, the number of heaters are limited, and it is hard to achieve precise control over the temperature of tin at any given location. In order to establish a good basic control, the free design parameters are optimized so that a steady state gradient of 50 K is achieved between solid (200°C) and liquid (250°C) tin in the working volume. This is done by evaluating the thermal profile of the system for different combinations of the design variables, using Finite Element Analysis. The two objectives of this optimization problem (maximum temperature gain and minimum crosstalk) are seen to have contrasting requirements of the design variables. An optimal combination of the variables is found such that a gradient of 50 K is possible, but with a little trade-off on both the objectives.Thirdly, a direct measurement of temperature of tin inside the pump is not feasible, and tin temperatures are estimated analytically. The accuracy of estimation is impacted by changes in local temperatures due to the non-linear properties of tin like absorption/release of latent heat, pressure-dependent melting point. The effect of non-linear tin properties on local temperature distribution is studied by setting up a finite difference model. It is seen that the absorption of latent heat during melting of tin results in a temperature that is 12 K lower than what would have been without the effect of latent heat.Materials Science and Engineerin

Micromechanical Characterization of TiN Films on 9Cr18 Steels
No full textTiN coatings 0.5mum thick were deposited by plasma are deposition on 9Cr18 steels. Vickers indentations, depth-sensing indentations and nanoscratches were produced with different tips on a broad range of applied load. Mechanical behavior of hard and brittle thin coatings on soft and ductile metallic substrates was investigated and interpreted. It is demonstrated that depth-sensing indentation and nanoscratch tests can provide more information about the near-surface elastic-plastic deformation, friction and wear properties. Compared with 9Cr18 steels, solid lubricating effects for TiN and organism/TiN coatings are very marked
Making SOA-based systems coherent and trustworthy
No full textUnder Service Oriented Architecture (SOA), a software system - such as one that supports an enterprise-consists of multiple heterogeneous servers. These servers may be distributed over
the internet, and may be managed under different administrative domains. SOA has become hugely popular, particularly as the architecture of large and complex distributed systems such as
enterprise systems, grids, virtual enterprises, and supply chains. Unfortunately, this architecture as it is currently defined and being used, suffers from serious problems as outlined below. First, there is no means to ensure that a fragmented and open system like a SOA-based system satisfies desired global constraints, or can establish any regularity over the system. Second, service providers can make their own commitments to clients. However, the SOA
methodology provides no guarantee to clients that the commitment made by a given server will be satisfied. Note that although service providers should have the freedom to specify their own commitments, they must conform to the global constraints imposed at large, and
such conformity must be enforced. Third, when using a composite service, clients indirectly communicate with services via an orchestrator. Such indirect interaction may cause concerns
for both clients and services, but no formal mechanism has been designed to address those concerns. Finally, it is not possible to ensure that coordination between disparate servers—called ”choreography” under SOA— is carried out safely and correctly. The overarching goal of my dissertation is to design a regulatory mechanism to address all these problems in a scalable manner. The mechanism is an extension of Law Governed Interaction (LGI) - a decentralized coordination and control mechanism for distributed systems. We call this mechanism ”LG-SOA”, for Law-Governed-SOA, which enables high expressive power, efficient enforcement, as well as good scalability. We will also present how LG-SOA can be applied to legacy systems. Case studies in the context of enterprise systems demonstrate the flexibility and applicability of this mechanism. Experiments show the overhead introduced by LG-SOA is relatively small, especially in the context of geographically distributed systems
like SOA-based systems. In sum, LGI-SOA is effective and versatile in making SOA-based systems more coherent and trustworthy.Ph. D.Includes bibliographical referencesby Tin La
