Transformer accessories are important components that complement the operation and maintenance of transformers. These power transformer accessories are designed to enhance the performance and lifespan of transformers, offering protection against various faults and abnormalities that may occur during operation. Some common transformer accessories include bushings, fans, conservators, tap changers, and cooling systems. Bushings are used to insulate and connect the transformer to the external power lines, while fans and cooling systems help regulate the temperature of the transformer to prevent overheating. Conservators, on the other hand, are used to provide additional oil storage and maintain the oil level within the transformer. Tap changers are important for adjusting the voltage levels of the transformer, ensuring efficient power distribution. Overall, transformer accessories play a crucial role in ensuring the smooth and reliable operation of transformers in various industrial and utility applications.
