Transformers TSL(Z)

Electrical devices that serve to convert electrical energy from one alternating current system to another without changing the power are called power transformers. They are one of the main elements of electrical installations and electrical networks. Depending on the direction of conversion, transformers are distinguished that step up or step down voltage. Dry transformers of the TSL type are a type of power transformer. They differ from other models by a design feature that involves the use of the natural environment as a cooler. This type of transformer requires minimal financial costs for maintenance, and is also economical and extremely easy to operate. The production of dry transformers has become a modern solution. It allows for the manufacture of a transformer design in which its magnetic system and windings are not immersed in transformer oil or any other liquid dielectric. The Invartrans company manufactures TSL dry transformers, fully adhering to the requirements of supervisory authorities and operating organizations. TSL transformers are most often installed in industrial premises or in public buildings, as they are subject to high requirements for fire safety, environmental friendliness and protection from explosions. This type of transformer is also used near technological sections of chemical, nuclear and metallurgical enterprises. Advantages of dry transformers over oil transformers: 1. Installation of TSL transformers ensures a high level of reliability, which is achieved with the help of a special technological manufacturing process. Dry transformers have the ability to function at the time of voltage overload, increased resistance to shock and alternating current, as well as resistance to pollution and humidity of the environment. 2. Thanks to the use of dry transformers, significant optimization of the operation of the existing electrical network is possible. When operating conditions change, reconfiguration of transformers is carried out as easily as possible. 3. Since the design of the transformer does not assume the presence of oil, this eliminates the possibility of its leakage and subsequent pollution of the environment. When operating TSL transformers, low noise levels are ensured and the emission of caustic and toxic gases into the atmosphere is excluded. 4. Significant space savings, which is achieved due to the compact dimensions of this type of transformers. An enterprise does not need to have a special room to install a TSL transformer. Power range 250-3150 kVA. Nominal voltage of the primary winding HV - 6; 10 kV. Voltage regulation of the PBB from the HV side - ±2x2.5%. Climatic version - U1, U3. Power transformers, three-phase, two-winding with natural oil cooling. Transformers of this type are made in a sealed design with complete filling with oil under vacuum. Temperature changes in the oil volume are compensated by a change in the volume of the corrugated walls of the tank due to their plastic deformation. The advantage of sealed transformers is that the oil has no direct contact with the atmosphere, excluding the ingress of moisture from the environment.
