product details
The dry type transformer produced by the company has been proved to be reliable in operation and has reached the national advanced level.This series of products adopt foreign advanced manufacturing technology,design drawings and technical documents complete,correct,clear,advanced production equipment,stable manufacturing process,complete measurement means,for the production of high-quality products to provide a solid guarantee.
SCB10 epoxy resin cast dry type transformer is manufactured according to the standard"dry type power transformer".In addition to the advanced process structure,resistance to short circuit,high level of shock,but also with resistance,moisture,dust,noise and low characteristics,can be deep load center.Widely used in high-rise buildings,airports,stations,docks,power plants,substations,etc.Especially suitable for flammable,explosive and other places with high fire requirements for installation and use.
The standard transformer produced by the company is without shell,and the protection grade is IP00.If the customer needs,the shell with the protection grade of IP20 and IP23 can be provided.The shell can be made of ordinary steel plate,stainless steel plate,aluminum alloy and other materials according to customers'requirements,and treated with acid pickling,phosphating,plastic spraying and so on.Temperature control display instrument and load recording instrument are installed on the low-voltage side of the shell,which is convenient for users to observe and safe and reliable.
Ii.Model and meaning
Iii.Performance and characteristics
High quality cold-rolled silicon steel sheet is selected as the core material,and the structure adopts 45-degree stepped full oblique joint,which is solidified in one,so as to improve the magnetic flux distribution at the joint,reduce the vibration energy of the core,and effectively reduce the no-load loss,no-load current and core noise.
The high-voltage coil is made of high-quality f-grade insulation channel wire and internationally advanced insulation material.The coil with large capacity is equipped with heat dissipation air duct along the axis.The structure has good resistance to current shock,temperature change,cracking and excellent heat dissipation performance.
The multi-stage segmental cylinder structure is adopted,which has strong over voltage capacity and very low partial discharge level.After vacuum drying,the casting and curing process of the coil are completed in accordance with the pre-compiled process curve.Precise process control ensures that the coil has no pores and holes.
Low voltage coils,adopting the foil structure can effectively solve the low voltage large current coil wire wound ampere-turns imbalance,in the form of foil coil at the same time there is no axial axial spiral Angle,number of turns and effectively eliminate the short circuit of transformer axial force,ensures that the current density inside the coil can freely according to the high voltage coil load distribution along the axial adjustment,reduced low-pressure sudden short circuit when the radial force.After winding,the end of the coil is sealed and cured by resin,avoiding the entry of various foreign matter and moisture.
Low loss,air loss and negative loss are all lower than national standard.Especially suitable for metallurgical,chemical and other high energy consumption manufacturing customers.
Low noise,far lower than GB and IEC standards,ISO14001 environmental protection system certification.Especially suitable for residential areas,hotels,schools and other places with high quiet requirements.
High reliability,good resistance to short circuit and 20%long-term overload.Especially suitable for high reliability requirements of power supply,such as hospitals,mines,factories,etc.
Good moisture-proof performance,can operate normally in humid environment.
Compact structure,small footprint;Easy installation,real maintenance free.
