Electrical Installations On Steel Structures – The Drive Station of Large capacity of The Belt Conveyor.

Author of photos and text: Radoje Jankovic.

Practice of electrical installations of low and high voltage for:

– pupils

– students

– technicians

– electricians,

– electrical fitters,

– engineers,

– designers and constructors,

– Professor …

In this photo album I showed dozens of photos of practical implementation of electrical installation on steel structures.

In this case, it is the drive station of belt conveyor with large capacity intended for a new surface mine field “C” in the mining basin “Kolubara” Lazarevac, Serbia.

These are the kind of specific electrical installation, which many do not have opportunities, perhaps never to see or to work on their execution. Although for a professional electrician does not have any specifics; installation as well as all electrical installations. Just a little more or a lot more complicated than the standard electrical wiring in the classic buildings and buildings.

Many, and professors have not seen such an installation let alone worked on them, installed, connected equipment, interrogated, let up, maintain and even rarely any of them that has ever designed.

Such installations are performed highly professional workers, technicians and engineers with extensive work experience. Younger colleagues are experienced with these “wolves electrics” trained and taught the craft to such an installation.

Even in schools and at universities with these and similar installations do not study, and a special problem is that schools and colleges do not send students to practice in enterprises where this type or similar electrical installations are performed, at least to get familiar with the specifics of jobs is working on how to perform them.

Jankovic is a big part of their working life working on editing and execution of many types of electrical installation of the; the ordinary family houses, apartment buildings, industrial buildings, hospitals, schools, large production hall at hydro power plants, diesel power plants, separations materials, concrete factories, cranes, excavators of all types of belt conveyors and spreader devices, drilling towers, oil fields, the separation of oil and gas installations, cathodic protection, small photovoltaic solar power plants, heating plants, technological plants, administrative and factory buildings etc. and so on.

Because of his work in a very different electrical installations Jankovic has a large archive and project documentation with complete calculations, materials specifications, Bill of Quantities work …. and a large number of their own, original photo detail of electrical installation of the execution.

Especially documented his masterful work embodiment thereof.

In this, the first part, I will show only the details with photographs.

Each image shows clearly enough what is necessary to see and even to learn something new. With each picture gives a short description for a clearer perception and understanding of the photos and details on it.

Otherwise, all the equipment is designed for outdoor installation and the most difficult climatic conditions. A climatic conditions in opencast mines are very harsh and extreme, flying to 45 or more degrees Fahrenheit in the winter frosts, snow and temperatures down to minus 20 degrees Celsius.

ELECTRICAL INSTALLATIONS steel structures.

Here we present details erection of electrical installation on steel structures, drive station a large belt conveyor for opencast mining of lignite coal.

In the later parts will be shown in many other details with different electrical equipment and devices both during installation and after completion, as well as details of installation in service after several years.

ELEKTRIČNE INSTALACIJE JAKE STRUJE NA ČELIČNIM KONSTRUKCIJAMA

Autor: Radoje Jankovic.

Praksa izvođenja električnih instalacija niskog i visokog napona za:

– učenike,

– studente,

– tehničare,

– električare,

– elektro montere,

– inženjere,

– projektante i konstruktore,

– profesore …

U ovom foto albumu prikazao sam nekoliko desetina fotografija praktičnog izvođenja električnih instalacija na čeličnim konstrukcijama.

U ovom slučaju, radi se o pogonskoj stanici jednog trakastog transportera velikog kapaciteta namenjenoj za novi površinski kop Polje “C” u Rudarskom basenu “Kolubara” u Lazarevcu.

Ovo su u neku ruku specifične električne instalacije, koje mnogi nemaju mogućnosti, možda nikada da vide ili da rade na njihovom izvođenju. Mada za električara profesionalca nema neke specifičnosti; instalacije kao i sve električne instalacije. Samo malo više ili mnogo komplikovanije od standardnih električnih instalacija u klasičnim zgradama i građevinskim objektima.

Mnogi, i, profesori nisu videli ovakve instalacije a kamo li na njima radili, montirali, povezivali opremu, ispitivali, puštali u pogon, održavali pa i retko koji od njih da ih je ikada projektovao.

Ovakve instalacije izvode visokostručni radnici, tehničari i inženjeri sa velikim radnim iskustvom. Mlađe kolege se uz ove iskusne “vukove elektrike” obučavaju i uče zanatu za ovakve instalacije.

Ni u školama a i na fakultetima sa ovakve i slične instalacije ne izučavaju, a poseban problem je što škole i fakulteti ne šalju učenike i studente na praksu u preduzeća gde se ovaj tip ili sličan električnih instalacija izvode, makar da bi se upoznali sa specifičnostima poslova koji se rade na izvođenju istih.

Janković je veliki deo svog radnog veka radio na montažama i izvođenjima mnogih vrsta električnih isntalacija; na običnim porodičnim kućama, stambenim zgradama, industrijskim halama, bolnicama, školama, velikih proizvodnih hala, na hidro elektrnama, dizel elektranama, separacijama materija, fabrikama betona, kranovima, bagerima svih tipova, trakastih transportera i presipnim uređajima, bušaćim tornjevima, naftnim poljima, separacijama nafte i gasa,

instalacijama katodne zaštite, manjih fotovoltaičnim solarnim elektranama, toplanama, tehnološkim pogonima, administrativnim i fabričkim objektima itd. itd.

Zbog svog rada na veoma različitim električnim instalacijama Janković raspolaže velikom arhivom i projektnom dokumentacijom sa kompletnim proračunima, specifikacijama materijala, predmerima i predračunima radova…. kao i velikim brojem sopstvenih, originalnih fotografija detalja izvođenja električnih isntalacija.

Posebno je dokumentovao svoj majstorski rad na izvođenju istih.

U ovom, PRVOM DELU, prikazaću samo detalje pomoću fotografija.

Svaka slika dovoljno jasno prikazuje sve što je neophodno da se vidi pa i da se nauču nešto novo. Uz svaku sliku dat je kratak opis radi jasnijeg sagledavanja i razumevanja fotografije i detalja na njoj.

Inače sva oprema je predviđena za spoljnu montažu i najteže klimatske uslove. A klimatski uslovi na površinskim kopovima su veoma surovi i ekstremni, leti do 45 pa i više stepeni Celzijusa a zimi mrazevi, sneg, temeprature i do minus 20 stepeni Celzijusa.

ELEKTRIČNE INSTALACIJE NA ČELIČNIM KONSTRUKCIJAMA.

Ovde su prikazani detalji izvodđenja električnih instalacija na čeličnim konstrukcijama, pogonske stanice jednog velikog trakastog transportera za površinski kop uglja lignita.

U kasnijim delovima biće prikazano mnoštvo drugih detalja sa različitom elektro opremom i uređajima kako u toku montaže tako i po završetku, kao i detalje instalacija u eksploataciji posle više godina.
