The rectifier transformer is the power transformer of the rectifier equipment.The characteristic of the rectifier equipment is the input current of the original party, and the deputy party outputs DC after the rectification is the original.Change flow is the general term of the three working methods of rectification, reverse flow, and frequency conversion. The rectification is the most widely used.The transformer for the power supply of the rectifier device is called a rectifier transformer.Most of the industrial rectifier power supply is obtained by AC Grid through rectifier transformers and rectifiers.

The role of rectifier transformer
The main purpose of the transformer is the transmission system.A high -voltage electric transmission can not only reduce the cross -area of ??the transmission line, save the introduction of human material materials, but also reduce the power loss of the transmission line.The transformer can also be used to change current, transform impedance, and generating pulse variable flow. It is the general term of the three working methods of rectification, reverse flow, and frequency conversion. The rectification is the most widely used.Another important role is to protect personal safety! Isolation dangerous voltage.Isolation means that the transformers original auxiliary edge around the coil is electrical insulation.The isolation of the transformer is the current of the isolation of the original auxiliary edge around the coil.There are many types of isolation. For common low -voltage transformers, it is mainly to apply insulating paint on the outside of the coil of the metal, and then the original auxiliary edge around the coil around a gate to form a transformer.Many people use the wires used by this transformer to call them "lacquer cables".The reason is that layer of insulation paint.At this time, the original auxiliary side rely on that layer of paint, that is, isolation.Auto -coupled transformers are applied in cases where primary and secondary isolations are required, and have the advantages of small size, small consumables, and high efficiency.
Rectification transformer instructions
The rectifier transformer winding generally uses a copper -conducting winding system. It is divided into a modified winding group, a high -voltage winding rowing winding, rectangular high -voltage winding, and a low -pressure winding.Some also include balanced electrical antibodies or saturated electrical antibody winding.Iron core: The iron core is composed of domestic or imported high -quality cold -rolled -oriented silicon steel sheets. Generally, a full -to -pore -free pulp zone or pull -board structure is adopted.The twelve phase of the single platform can also be used.箱体：由优质钢板焊接而成，分为箱盖式及半钟罩式波纹油箱结构，美观、强度高;中小容量、阀侧出线较少的，采用箱盖式顶部出线;大容量、阀The side line is available on the side of the half -hood.In order to reduce vortex losses, magnetic measures are taken around the side of the valve side.
Principles of rectified transformers working
The rectifier transformer is connected to the AC grid first, and the secondary silicon rectifier is also called the valve side. The waveform of its output is not a sine wave. According to the requirements of the rectifier device, the valve side connection method is different.The general purpose is: electrification or electrolytic, traction, transmission, DC transmission, electroplating and electrical processing, excitation, charging, stringing speed regulatory use and electrostatic dust removal.Simply put, 1) After the transformer lowering the voltage, 2) The rectifier pipe makes the original pure AC power into a smooth or pulse DC power, 3) then appropriately filter through the appropriate capacitor filtering.
Rectifier transformer model
Z-Pinyin is "zheng", which means the meaning of rectification; H-Pinyin is "HE", and the iron core material is an amorphous alloy; S-Pinyin is "SAN", which represents three phases; K-Pinyin is "kang".The meaning of high impedance.Combining together is- "Three-phase High Image UNACO Rectifiers Rectifiers" transformer model has industry standards, the standard number is JB/T3837-1996
