What are TMH Transformers: Features and Advantages

TMH transformers are high-efficiency three-phase oil transformers with two windings that provide on-load voltage regulation (OLC) with an accuracy of ±4x2.5%. They are designed for applications with maximum input voltages up to 110 kV and capacities from 1000 kVA to 6300 kVA. These transformers are ideal for industrial and distribution networks, providing efficient power transmission with minimal losses.

TMN transformers have natural oil cooling, which ensures durability and reliable operation under various climatic conditions. They are equipped with modern voltage regulators and can be used in regions with temperatures from -50°C to +40°C. Such devices ensure stable operation of power grids and guarantee high efficiency throughout their entire service life.

General characteristics of Transformer TMN

TMN transformer is a highly efficient three-phase oil transformer with natural cooling, designed for electric energy conversion (voltage reduction or increase) in electrical networks with a frequency of 50 Hz. It provides stable power supply for industrial and distribution networks, guaranteeing reliable operation even in difficult conditions.

Operating conditions of the TMH Transformer

The TMH transformer is designed to operate over a wide temperature range, which allows it to be used in various climatic conditions. The optimum ambient temperature for its operation is from -40°C to +40°C, while the range can be extended to -50°C for operation in colder regions. These transformers are ideal for operation in areas with moderately cold climates and guarantee stable operation even at extreme low temperatures.

  • Installation height: up to 1000 meters above sea level.
  • Environment: it is recommended to avoid operation in areas with conductive dust, aggressive gases or chemically active substances.
  • Vibration and shock: TMH transformers are not designed to operate under severe vibration or shock loads.

Design and features of TMN Transformer

TMN transformer consists of high quality components that ensure durability and high efficiency of the device:

  • Case: made of welded metal construction with elliptical or rectangular shape. Strong connections and tightness are achieved by using oil-resistant rubber products.
  • Magnetic system: made of cold-rolled electrical steel, which minimizes energy losses and increases the reliability of the transformer.
  • Windings: High and low voltage windings are made as block coils of copper or aluminum, which ensures excellent conductivity and durability.
  • Cooling: natural oil cooling, which reduces operating costs and extends transformer life.

Construction and device features

  • Magnetic system: The transformer is equipped with flat layers of magnetic elements made of cold rolled electrical steel, which helps to minimize losses and increase the efficiency of the device.
  • Windings: The winding design includes several layers with an annular cylindrical connection for the high voltage winding. It is important to note that special regulation coils are provided to control the voltage under load.
  • Overload and short-circuit stability: TMN transformer has a high resistance to overloads and short circuits, which ensures its safety and reliability.
  • Housing construction: The transformer has a robust design with a hermetically sealed enclosure that can withstand up to 35 kPa of overpressure.

Standards and certification

The TMN transformer complies with international quality standards including GOST, CE and UL. It is certified for GOST 15150 climatic conditions, categories U1 and UHL1, which allows its use in various temperature and operating conditions. This guarantees high quality and compliance with strict international requirements.

Main parameters of the Transformer TMN:

  • PowerFrom 1000 kVA to 6300 kVA.
  • Voltage: high - 6 kV, 10 kV, 20 kV, 35 kV, 110 kV; low - 0.4 kV, 0.69 kV, 3.15 kV, 6.3 kV, 10.5 kV.
  • Defense: protection class IP00.

TMH transformer is a reliable solution for ensuring stable and efficient power supply in industry and distribution networks, as well as in other areas where high quality power conversion devices are required.

Operating principle of the TMH transformer

The TMN transformer operates on the basis of the principle of electromagnetic induction. Voltage is transferred between the two windings by means of a magnetic field, which allows to change its characteristics depending on the required network parameters. This process makes it possible to effectively increase or decrease the voltage, which is important for ensuring stable power supply in distribution and industrial networks.

The main components of the TMH transformer:

  • Case: is made of welded metal construction, which ensures rigidity and tightness of the unit. Strong connections prevent oil leakage and increase the service life of the unit.
  • Magnetic system: is made of cold-rolled electrical steel, which minimizes energy losses and contributes to high operating efficiency.
  • Windings: The high-voltage and low-voltage windings are in the form of block coils made of copper or aluminum. They provide excellent conductivity and durability.
  • Oil tank: hermetically sealed design that protects the transformer oil from external contaminants and increases the reliability of the device.
  • Terminals: are used to connect the transformer to the electrical network, providing reliable current input and output.
  • Instrumentation: to monitor the transformer status, which allows timely detection of possible malfunctions and prevention of breakdowns.
