Solving urgent issues of energy saving, we offer a new development - TMG33 transformers with a power of 63 . . . 630 kV · A. This series of transformers was developed in accordance with the standards of PJSC ROSSETI STO 34.01 - 3.2 - 011 - 2017, Power Distribution Transformers 6 - 10 kV with a capacity of 63 - 2500 kV · A. Requirements for the level of idle and short circuit losses. ” The level of idle and short circuit losses in the TMG33 series of transformers corresponds to the energy efficiency class X2K2. The energy efficiency class X2K2 satisfies the requirements of Decree of the Government of the Russian Federation of June 17, 2015 No. 600 “On approval of the list of facilities and technologies that relate to facilities and technologies of high energy efficiency”.
TMG33 three - phase oil transformers are designed to convert electricity in the networks of power systems and electricity consumers in an outdoor or indoor installation of moderate (from plus 40 to minus 45 ° C) or cold (from plus 40 to minus 60 ° C) climates. The environment is non - explosive, does not contain dust in concentrations that reduce the parameters of products in unacceptable limits. Transformers are not designed to work in conditions of shaking, vibration, shock, in a chemically active environment. Installation height above sea level no more than 1000 m.
The low voltage winding of the transformers of this series is not made of aluminum wires, but of aluminum foil, which combines the simplicity of winding with a high level of reliability.
Rated frequency 50 Hz. Voltage regulation is carried out in the range up to ± 5% on a completely disconnected transformer (ПБВ) by switching the branches of the HV winding in steps of 2.5% .
According to GOST 11677, the maximum deviations of the technical parameters of the transformers are: short - circuit voltage ± 10% ; short circuit loss on the main branch + 10% ; loss of idling + 15% ; total weight + 10% .
To control the oil level in the transformers, a float type oil indicator is provided.
To prevent overpressure in the tank, a safety valve is installed in excess of the permissible pressure in the transformers.
To control the internal pressure in the tank and alarm if it exceeds the permissible values in the transformers placed in the room, an electrocontact manovacuum meter is provided for by the customer’s order.
To measure the temperature of the upper layers of oil on the transformer cover, a sleeve is provided for installing a liquid glass thermometer, which transformers are equipped with upon request of the consumer.
To measure the temperature of the upper layers of oil and control external electrical circuits, transformers designed for operation in a room or under a canopy are equipped with a manometric signaling thermometer by order of the consumer.
The neutral inlets and outlets of the LV transformer windings are designed for continuous load with a current equal to 100% of the rated voltage of the LV transformer winding.
Transformers are equipped with transport rollers (63, 100 and 160 kV • A - on request of the consumer) for moving the transformer in the longitudinal and transverse directions.
