Product Description:

Type description

Technical characteristic
1.It accords to the GB1207-1997<voltage transformer> ,IEC186 and IEC60044.
2.This product has the character of limited tightness.All the tightness compartment do not be put into ultraviolet radiation so that we solve the problem of chap of tightness rubber and aging,these product is more reliable and has longer life,we ensure that it can run 20 years without leakage.
3.The porcelain is equipped with irragateing flange.the surface of flange use hot zincification to enhance the wholly mechnism of product and has beautiful outlook.
4.This product is equiped with bellow and is tightnesds completely.
5.With higher accuracy to 0.2,we can reach the requirment of customer with seperatly measuring secondary winding and protection winding.
6.With epoxy secondary terminal board,the product is enhanced secondary insulation and tightness.
7.All the standard comparthent are plated Dakelo.We ensure that the product don't rust for 20 years.
8.The inner structure of this product has changed largly and we solve the problem of old 35KV PT with unreasoned inner structure for the unpassed dielectric loss,This product has low partial discharge and litter dielectric loss with advanced workcraft.
9.The excitaton density of this product is equal or less than 0.7T and has the ability of avoiding ferro-resonance.

Q:What is the M of the transformer capacity MVA?
MVA with a table of his capacity, read: trillion volts in which M with a sign The conversion unit is 1MVA = 1000KVA = 1000000VA
Q:Who knows the density of the transformer oil is how much?
Temperature at 20 ° C: Normal value typical 25 # transformer oil: 895kg / m3 877.6kg / m3 45 # transformer oil: 895kg / m3 879.0kg / m3
Q:Know the rated capacity of the transformer, how to calculate its rated current?
Low-voltage 400V distribution transformer speed calculation: per thousand volts by 1.44A, per thousand kVA of 144 ac current calculation. Formula algorithm: Three-phase transformer current I = Pe / Ue / √3 Single phase transformer current I = Pe / Ue
Q:Is the transformer a power adapter?
It depends on the transformer voltage, current, power and other data can be suitable for your job requirements of a machine. Such as computers
Q:What is the primary side of the transformer
Step-down transformer: primary side of the high-pressure side (primary side) Secondary side refers to the low side (secondary side) Boost transformer: primary side of the low side (primary side) Secondary side refers to the high pressure side (secondary side)
Q:Why is the transformer ah?
The AC power up and down operation. The So as to get the desired AC voltage
Q:What is the meaning of the Y D11 on the transformer?
Transformer Y / D11 Y ----- primary side connection, star type, D secondary side connection, triangle 11 is the primary and secondary side of the phase difference of the side line voltage lag secondary side 330 degrees (or lead 30 degrees).
Q:What does S11-M-500/10 transformer mean?
S represents three phases 11 design number M indicates sealing 500 indicates that the transformer capacity is 500KVA 10 indicates that the rated voltage of the transformer high voltage side is 10KV
Q:220V to 12V transformer L N + V + V on behalf of what? The more detailed the better! Thank you prawn
LN represents the line of fire and zero line, + V is the input and output voltage
Q:Transformer turns around the number and how much V is calculated
Transformer turns around the number and how many V calculation method: 1. Find the number of turns per volt: Number of turns per revolution = 55 / core cross section For example, the core section = 3.5 ╳ 1.6 = 5.6 square centimeters Therefore, the number of turns per revolution = 55 / 5.6 = 9.8 turns
