What Are The Main Reasons Why The Outdoor Busbar Joint Of The Transformer Is Prone To Heating?

The main reasons why the outdoor busbar joint of the transformer is prone to heating include the following:

High ambient temperature: In a high temperature environment, the outdoor busbar joint is exposed to direct sunlight, which makes it difficult to dissipate heat and is prone to overheating.

Poor joint quality: Poor joint quality and poor contact can easily cause excessive resistance and generate a lot of heat energy, which can lead to joint overheating.

Excessive current load: If the current load is too large, the resistance at the joint is likely to increase, which will in turn generate a lot of heat energy.

Equipment aging: After long-term use, the outdoor busbar joint may have corrosion, aging and other problems, which can easily cause poor contact and excessive heat.

Natural environment erosion: The outdoor busbar is often eroded by wind, rain, snow, sun, freezing, etc. These factors will accelerate the oxidation, corrosion and damage of the busbar joint, causing the joint contact resistance to increase and the temperature to rise.

 

Methods to prevent and solve the heating of the outdoor busbar joint include:

Select materials with excellent electrical conductivity and high temperature resistance as joint materials.

Increase the heat dissipation area and cool the surrounding environment of the outdoor busbar joint.
‌Strengthen the repair and maintenance of the joints, conduct regular inspections, and avoid problems such as poor contact. ‌ ‌According to the characteristics of the equipment, reasonably select the current load to avoid excessive heat energy caused by excessive current. ‌ ‌Replace or repair the busbar joints that are seriously aged in time to ensure the safe operation of the equipment. ‌
