How to select right transformer for mining industry, instructions by leading transformer manufacturing company
Introduction
Mining industry is
highly important in each country as it contributes in large sums to the
national income. For the mines to work efficiently, they require continuous and
reliable supply of power. They require power for a variety of purposes such as to
power shovels and drills for excavating these products, loading them into enormous
mining trucks, sorting, sifting and crushing ores, heating etc. This fact is
well known by the transformer exporters in India, Rajasthan Powergen.
The Role of
Transformers
For both underground
and surface mining the power centers or load centers are highly important as it
is here that the distribution voltage is made usable by converting into
utilization voltage. This requires careful selection of the right transformer
which can fulfill right safety, reliability and efficiency requirements.
Transformer Losses
Transformer losses
are a transformer operating below its capacity. This can be due to fault or
inefficiencies in the core of the transformer. If the transformer works at 100%
load the amount if loss is nothing but if transformer operates at load below
that, then it seems like waste of energy. These days the load runs between 34
to 50 % of the transformer’s capacity. Thus it becomes imperative to run
transformer at minimal losses as they are the backbone of mining industry.
Liquid Filled and
Dry Transformers: Performance Characteristics
1.Liquid-Filled
Transformers
Liquid-filled
transformers are highly efficient greater overload capability and also have
longer life expectancy. They are smaller in size and because of their better
thermal dissipation characteristics exhibit lower losses.
2. Dry Type
Transformers
Dry type
Transformers utilised for lower ratings and are placed generally placed
indoors. They don't use any kind of flammable material and thus pose no danger
of fire hazard when even used in underground mines.
The Need for
Energy-Efficient Mining
Apart from the need
of energy efficient mining for increasing profits there is the concern of being
environment safety and responsibility also. For this the mining companies are
doing everything like using NEMA-approved transformers and harnessing solar or
wind energy. It is highly crucial to come up with ways and means to utilise
energy by conserving it at the same time.
Energy efficient transformer manufacturers in India, Rajasthan Powergen recognise
the need for energy efficient transformer in the mining industry for the
various applications like auxiliary lighting loads to power for cranes, drag
lines, conveyor belts and other miscellaneous dedicated variable speed drive
applications and for making the mining industry run at minimal cost and maximum
profit.
