The dehydrating breather type L is used to dry the intake air of transformers.
If the operating temperature of the transformer drops, air will be sucked in through the oil container, cleaned of dirt particles and subsequently dried by the silica gel inside the assembly groups B1 and B2 (optional).
The oil trap prevents any permanent contact between the silica gel and the moist ambient air and also filters the inflowing air. If the temperature rises, air is expelled from the conservator and flows through the transformer dehydrating breather type L in the opposite direction. The size of the dehydrating breather which has to be used depends on the oil volume and the frequency of the air exchange.
During the breathing cycle of a transformer, it is crucial to prevent atmospheric moisture from entering the transformer, which can contaminate the oil and cause damage over time to internal parts. The transformer windings are insulated with cellulose paper and fully submerged in insulating oil, both of which have very high dielectric strengths. When the insulating oil becomes contaminated with moisture, it can cause a number of issues inside the transformer. These include, but are not limited to, decrease in the dielectric strength of the oil and cellulose, accelerated breakdown of the insulating cellulose paper increasing the risk of partial discharge, increased risk of bubble formations at higher temperatures, and the condensation or accumulation of this moisture during cooling which can cause corrosion inside the tank leading to further problems.
Transformer dehydrating breather type L consists of at least one upper part (B1) and the oil trap (OV). Depending on the requirements, further intermediate parts (B2) can be added which are filled with 1.2 kg of silica gel each.Upon requestthe connection parts are available in A4 stainless steel.
We also offer transformer dehydrating breathers as corrosion resistant version with aluminium housing as well UV-resistant C5-M powder coating. For more detailed benefits, kindly refer to benefits at a glance below.
Under normal transformer operating conditions, insulating oil temperature regularly changes with fluctuations in load and ambient conditions. During heavy loading conditions, the oil temperature rises, which causes an increase in oil volume inside the transformer. On the contrary, under light loading conditions, oil temperature cools causing a decrease in oil volume. In a conservator-style transformer, this movement of the oil level causes what is referred to as the transformer “breathing” cycle, as air is brought into the tank and then expelled again later.
