transformer

Iron core: It is the core skeleton of a transformer, consisting of iron core columns and iron yokes. It is generally made of cold-rolled silicon steel plates with high conductivity and low specific energy consumption. Common forms of iron core laminations include strip iron row laminations and involute iron cores. The cross-section of the iron core columns can be square, rectangular, or trapezoidal.

Winding: also known as a coil, is the part of a transformer that conducts current. It is usually made up of insulated copper or aluminum wires wound together, and can be divided into concentric and overlapping types according to its shape and structure. Concentric windings include cylindrical, segmented, spiral, and continuous types, while overlapping windings are also known as cake windings.

Other Accessory

Oil tank: Used to hold transformer oil, it plays a role in insulation and heat dissipation. Transformers with medium capacity or above generally adopt a sealed oil tank structure.

Safe airway: also known as explosion-proof tube, when the internal pressure of the transformer is too high, it can divert the oil and gas generated by gasification to prevent damage to the oil tank.

Gas relay: It is a protective device for transformers. When abnormal conditions occur inside the transformer, such as high temperature or pressure imbalance causing oil volatilization and decomposition or generating impact oil flow, the relay contacts will actuate, issuing an alarm signal or tripping the transformer.

Tap changer and tap changer: Tap changers are used to adjust the turns ratio of the primary and secondary windings. Tap changers are divided into on load voltage regulation and no-load voltage regulation. By connecting to different tap changers, the turns of the primary winding can be changed to regulate the output voltage of the transformer.

Insulation sleeve: used to lead high-voltage leads out of transformers, providing insulation protection and fixing the leads.
