What are traction transformers?
Traction transformers are specialized transformers designed for use in railway and tram systems. Their main function is to convert high voltage electrical energy from the network into a lower voltage suitable for the traction systems that drive electric trains or trams. Traction transformers are designed to withstand the harsh operating conditions typical of railway environments, such as vibration, shock and extreme temperatures, ensuring reliable performance and safety.
A traction transformer is a type of transformer used specifically in the railway industry to provide electrical power to locomotives and electric trains. It steps down the high voltage of the electrical supply network to the lower voltage required for the train’s traction motors and other systems. These transformers are usually installed in traction substations along railway tracks, where they play a crucial role in ensuring a stable and efficient supply of electricity for train operations.
A traction electrical substation is an installation that converts high voltage electrical energy from the main electricity network into lower voltages suitable for rail or tram systems. It houses traction transformers as well as other equipment such as circuit breakers, switchgear and control systems. The substation ensures that electrical energy is supplied reliably and efficiently to the traction network, thus enabling the operation of electric trains or trams.
Transformers are electrical devices used to change voltage levels in alternating current (AC) circuits through electromagnetic induction. They can increase (raise) or decrease (lower) the voltage between circuits while maintaining the same frequency. Transformers are used in a wide range of applications, including power distribution, voltage regulation and electrical insulation, to ensure that electrical energy is transmitted and used efficiently through the various stages of electrical systems.
What is a traction transformer?
There are several types of transformers, including:
Step-up transformers: increase the voltage from the primary winding to the secondary winding.
What is a traction electrical substation?
Step-down transformers: Decrease the voltage from the primary winding to the secondary winding.
Isolation transformers: provide electrical isolation between circuits while maintaining the same voltage.
Autotransformers: Use a single winding to serve as both primary and secondary, with a variable tap to adjust the voltage.
Toroidal transformers: feature a donut-shaped core to reduce electromagnetic interference and a compact design.
Power Transformers: Used in high voltage applications for power transmission and distribution.
Distribution Transformers: Used to step down voltage for safe delivery to end users in residential or commercial areas.
Welding Transformers: Used specifically in welding applications to provide appropriate voltage and current for welding processes.
