Lions Baseball Cap

Lions Baseball Cap -

One characteristic of all transformers, regardless of size, style, or construction, is that when energized, they create losses in the circuit.

Some of these losses are from energizing the core and creating a magnet field, and some losses are resistive losses (I2R) from load currents flowing in the conductors of windings.

Both types manifest themselves in the form of heat, and heat is the number one enemy of insulation material.

The task for transformer designers is thus to allow transformers to dissipate excess heat and thereby ensure longer insulation life.

For air cooled transformers this is accomplished by providing adequate ventilation and cooling ducts in the coils. Where Lions Baseball Cap there is not enough air flow, fans are added to increase heat transfer away from magnetic elements and vulnerable dialectic insulating components.

For liquid filled transformers the approach is similar. Cooling ducts in the coils must be in sufficient number and size to allow dielectric fluid to flow through the coils to remove heat. This fluid can move by simple convection, or it can be "force cooled" by pumping fluid.

Additionally, the tank surface must be large enough to transfer Lions Baseball Cap heat away from the fluid by a combination of conduction, convection, and radiation. As transformers get larger, tank surface area becomes a constraint, and external radiators are added to Lions Baseball Cap increase the surface area for heat transfer. To maximize this process, cooling fans can be added to expedite the heat removal through radiators.
