Introduction to the internal structure of the rectifier transformer

The core of the rectifier transformer is made of cold-rolled silicon steel sheet. In larger transformers, in order to reduce the no-load loss, the core sheet adopts full oblique joints. The overall structure of the core adopts the imported advanced technology.

The grid-side coils are mostly of continuous structure, the voltage-regulating coils are mostly of layered structure, and the valve-side coils are generally of double-cake structure. Because the electronic computer is used to calculate the electric field and the impact characteristics of the coil, the coil structure has excellent electrical properties. properties and impact strength.

For larger rectifier transformers, the oil tank adopts a foldable structure, which not only beautifies the appearance, but also greatly improves the mechanical strength of the oil tank.

The valve side outlet has both the box top outlet and the box wall outlet, which facilitates the connection with the rectifier.

The outgoing terminal on the valve side of the rectifier transformer adopts epoxy casting to form a low-voltage conductive rod, which makes the transformer beautiful and compact in appearance.

The transformer is equipped with various protection devices such as thermometers, gas relays, voltage releasers, mutual inductors, etc. For high-voltage products, a diaphragm oil conservator is used to ensure the safe and reliable operation of the transformer.
