Introduction to the bushing of DC charging pile transformer
The bushing of a DC charging pile transformer is a critical component that primarily serves to connect the transformer's windings to the external circuit and provide insulation and protection. Here is some information about the bushings in transformers for DC charging piles:
Main component
Insulation and Protection
Transformer bushings are typically made of insulating materials such as ceramic or glass, which can withstand high voltages while protecting the windings from environmental influences like humidity, dust, and other contaminants that could damage the windings.
Connecting Windings
Bushing connects the transformer's windings to the external circuit, allowing for the flow of current in and out. They serve as a bridge between the transformer windings and the power grid or other electrical equipment.
Preventing Arcs
During the operation of tap changers, bushings help prevent the generation of arcs, which can damage transformer oil and windings. The design and material of the bushings help to disperse the electric field, reducing the risk of arcing.
Pressure Relief
In some cases, bushings can also act as pressure relief devices, preventing the transformer from being damaged due to excessive internal pressure.
Temperature Monitoring
Some bushing designs include temperature monitoring devices that can monitor the temperature of the transformer oil in real-time, which is crucial for maintaining the proper operation of the transformer and preventing overheating.
In summary, the bushings of a DC charging pile transformer provide not only electrical insulation but also protect the transformer from environmental influences, making them an essential part of ensuring the safe and reliable operation of the transformer.
DC CHARGING PIlE SERIES
DC charging pile is an efficient charging facility for electric vehicles, which uses direct current (DC) to directly charge the vehicle battery, significantly reducing the charging time. Compared with traditional AC charging piles, DC charging piles are able to provide higher power output and can usually charge an EV to 80% of its capacity in 30 minutes, providing users with a convenient charging experience.
