SCBH15 Series

Amorphous Alloy Core Dry-type Transformer





SCBH15 series amorphous alloy core dry type transformer is an efficient and energy savingnew type distribution transformer. It is acombination of technologies of amorphous alloy transformer and cast resin dry typetransformer and has the advantages of oil free, flame retardant,self extinguish, resistant to moisture, anti-cracking, free maintenance, and especiallylow no load loss. It has been widely used in railway, airport,station, high building, business center, and industrial and miningenterprises. It is particular well suited to inflammable andexplosive places.


Characteristics

●Low loss

Especially no load loss, 75% lower than ordinarytransformer at the same capacity, drastically reducingits operating cost and has obvious effect on energy-saving.


●Strong anti-short circuit capacity

Three-phase five-limb structure and frameprotection structure around iron core effectively ensure the capability of anti-short circuit.


● Low noise

The combination of reasonable design and carefultechnique makes the noise of products lower than the requirement of nationalstandard JB/10088.


● Highhumidity proof  

HV&LV coils arevacuum epoxy cast resin, can be operated in 100% relative humidityand other harsh environment.


● Low temperature rise

Coils adopt thin resin structurewithout cracking and have strong ability for heatdissipation and overload.


● Flame resistance, self-extinguishment, explosion proof and no pollutionto environment

Glass fiber and other insulating materials used in coilsare self-extinguish and can not cause fire hazard because of electric arcproduced by short circuit.

Q:What is the role of the pebbles in the transformer base
Accident oil pool. Linyi pebble production base. Specializing in the production and sale of transformers mats pebbles.
Q:Transformer input power how to ask?
Transformer calculates power factor If the capacity of the power transformer is denoted by S, the output active power is expressed by P, then the power factor cosa = P / S.
Q:What is the meaning of the transformer capacity unit KVA?
KVA for apparent power, its size and power factor! For example: power factor cosΦ = 0.8 active power P = 1Kw Then tgΦ = 0.75, so the square of the apparent power S = the square of P + the square of P * tgΦ When the power factor is 1, 1KVA = 1KW
Q:What are the transformer capacity?
Transformer capacity has the following (unit kVA): 10 20 30 50 80 100 125 160 200 250 315 500 630 800 1000 1250 1600 2500 and so on
Q:S11-1250kVA transformer oil capacity how much
S11-1250kVA transformer oil capacity is 550kg, the pressure of the relevant information will be marked on the nameplate, the nameplate has the relevant parameters.
Q:From the variable ratio to determine whether the transformer is boost or buck
High pressure to low pressure is the buck, and vice versa is boosted. That is, the input transformer is a high voltage, the output is a low voltage is a low voltage.
Q:How to use the experimental method to determine the transformer iron consumption and copper consumption
Is it in the motor experiment? The power measured by the no-load experiment is iron loss, and the power measured by the short-circuit experiment is copper consumption.
Q:Proteus transformer how to adjust the parameters, the 220V into 14V output.
Transformer parameter setting method is: 1, the calculation: According to the ideal transformer primary turns ratio ratio n1 / n2 = V1 / V2 = 220/14 ≈ 15.7,              Let the primary winding sense L1 = 1H, then the secondary winding inductance L2 = 1 / (15.7 ^ 2) ≈ 0.00406H,
Q:How to increase the transformer output current
2, Transformer (Transformer) is the use of electromagnetic induction to change the principle of AC voltage device, the main components are primary coil, secondary coil and core (core). The main functions are: voltage conversion, current conversion, impedance conversion, isolation, voltage regulator (magnetic saturation transformer) and so on. According to the purpose can be divided into: power transformers and special transformers (electric furnace change, rectifier, frequency test transformer, voltage regulator, mine transformer, audio transformers, IF transformers, high-frequency transformers, impact transformers, instrument transformers, electronic transformers , Reactors, transformers, etc.). Circuit symbols commonly used as the beginning of the number. Example: T01, T201 and so on.
Q:Three-phase transformer how four ways to connect it?
Three-phase transformer solution Yy Dd Yd Dy these four connections each connection there are many connections such as Yy-10 According to the original side of the different phase has a different solution, and whether the grounding (N) connection is also different
