Description
Technical Field
The utility model relates to a transformer technical field that adjusts the temperature specifically is a forced-ventilated formula transformer attemperator.
Background
A Transformer (Transformer) is a device that changes an alternating-current voltage by using the principle of electromagnetic induction, and main components are a primary coil, a secondary coil, and an iron core (magnetic core). The main functions are as follows: voltage transformation, current transformation, impedance transformation, isolation, voltage stabilization (magnetic saturation transformer), and the like. According to the application, the method can be divided into: power transformers and special transformers (furnace transformers, rectification transformers, power frequency test transformers, voltage regulators, mining transformers, audio transformers, intermediate frequency transformers, high frequency transformers, impact transformers, instrument transformers, electronic transformers, reactors, mutual inductors, etc.). Transformers generally use an iron core made of silicon steel as a main magnetic circuit. Thus, the magnetic field in the coil can be more concentrated, and the transformer is more compact. The core of the power transformer must be designed to prevent saturation of the magnetic circuit, and sometimes some air gaps are designed in the magnetic circuit to reduce saturation. The actually used transformer iron core is formed by laminating silicon steel sheets with very thin and large resistance. This reduces the losses and heat generation associated with each layer of eddy current. Power transformers and audio circuits have similarities. Typical laminated cores are generally in the shape of E and I letters, called "EI transformers". One problem with such cores is that residual magnetism is maintained in the core after a power failure. When energized again, the residual magnetism causes the core to temporarily saturate. For some transformers with capacities in excess of hundreds of watts, the inrush current can cause the main fuse to blow if no current limiting circuit is used. More seriously, for large power transformers, the inrush current can cause deformation and damage to the primary winding. The transformer is unfavorable when the temperature is too high and too low during operation, and the transformer life-span is influenced to the temperature is too low, and when the temperature is too high, transformer efficiency reduces. The existing cooling device for the transformer, particularly the dry-type transformer, is simple, most of the cooling devices utilize natural wind for cooling, and the cooling device cannot control the air flow distribution and achieve the aim of temperature control.
