Amount, the coolant that can be flowed by water cooled path takes away, and makes the transformator can long term maintenance cold operation, it is ensured that product life-time service
Reliability.And, secondary coil uses pipeline configuration, decreases the use of conductor material, makes the weight of transformer body more
Few, contribute to realizing the lightweight of product.
The armature winding of this transformator is made up of several primary coils.For ensureing the coolant energy of water cooled path flowing
Fully taking away the heat of armature winding and secondary windings, the cross section of this primary coil can be rectangular, and the cross section of secondary coil can be in
Rectangle, and primary coil is distributed in distance with secondary coil so that the surface of secondary coil can to greatest extent with primary line
The surface of circle contacts, in order to heat taken away by coolant.
For ensureing the sealing in water-cooled path, transformer body can use the mode of overall injecting glue encapsulation to realize sealing, i.e.
Iron core, armature winding, secondary windings and related components are arranged in cavity, and output unit is arranged on the top of cavity
After, inject fluid sealant toward cavity so that it is form overall structure, thus ensure the sealing in water-cooled path, it is achieved electricity separation.
For obtaining variations in temperature during transformer body work, the flow of the coolant in adjustment water-cooled path, chamber in real time
Internal it is provided with temperature-sensing probe.The working power that temperature-sensing probe is connected to the external world by wire is connected, and obtains transformator in real time
The variations in temperature of main body, in order to user according to the range of temperature of transformer body, adjusts coolant in water-cooled path
Flow, it is ensured that transformator long term maintenance cold operation.
The present invention has heat dispersion excellence, overall operation temperature rise is low, good reliability, noise are little, water-cooled path seal
The advantages such as excellent, product weight is light.
