Railway balance traction transformer
|
| Railway balance traction transformer is the main transformer in the traction substation of railway electrification.It can suit for traction electrification performance characters,such as short-time serious over-load,3-phase unbalanced load,frequent close to earth short-circuit,etc.It has the distinguishing features of low loss,high mechanical strength,simple constructure,convenient manufacture.Because of traction transformer's long working in no-load condition,the proportion of no-load loss to load loss is selected reasonable in order to be in transformer economic performance during designing. |

YN.A connection traction transformer |
The transformer series is the main transformer in the traction substation of railway electrification.It transformers 110kV directly to 27.5kV,and connects to the traction network to supply power for electric traction locomotive.Transformer,whose rated power is 10~63MVA,can suit for traction electrification performance characteristics,such as short-time serious over-load,3-phase unbalanced load,frequent close to earth short-circuit,etc.Its main performance features:1.primary 3-phase currents are always balanced system and have no zero-sequence current,so as to eliminate negative sequence component and harmony wave component,and also raise electrification quality,reduce harm to electric equipment.2.Primary 3-phase power is equal to secondary 2-phase power,utilization ratio of transformer power is 100%,so as to reduce production costs raise economic efficiency of electric railway.

Vv connection traction transformer |
Vv connection traction transformer is a new product developed by our company for the needs of the market and enterprise development.It can raise utilization ratio of transformer power,decrease transformer volume,reduce transformer loss production costs.Because the active part of transformer is composed of two single-phase active parts,it is easy to take steps to improve and strengthen the ability of withstanding short-circuit.
main usage: Fitting for electric railway BT supply power. |

Single phase traction transformer |
| Single traction transformer utilization ratio of power is 100%,higher than Ynd11 transformer,so as to save a lot of performing costs.Its constructure is simpler than 3-leg core,one-phase coils are assemblied seperately into two legs of core in order to cut half down ampere-turns and strengthen the ability of withstanding short-circuit.Users can select rated power of single traction transformer reasonable according to the actual load,so as to aviod waste of transformer power.The products have low noise,low temperature-rise,high ability of over-load and long life. |
