Three - phase dry power transformers with cast resin series TSL, TSZL, TSZLF, TSZL11, TSZLF11, TSDL, TSDZL, TSDZLF, TSDZL11, TSDZLF11 with a system of natural and forced cooling of voltage classes up to 10.5 kV rated for power conversion at a frequency of alternating current 50 Hz. Transformers are designed for indoor operation. Transformers are equipped with self - produced windings. Three - phase dry power transformers with geafol cast insulation with voltage up to 10.5 kV are designed to convert electricity in power grids and consumers of alternating current electricity with a nominal frequency of 50 Hz. Transformers are equipped with self - produced windings, winding material - aluminum. Additionally, the windings are reinforced with fiberglass, which excludes the occurrence of cracks in the epoxy compound even when the transformers are overloaded. Thanks to this insulation, the windings are maintenance - free. To measure and control the temperature, the transformers are equipped with a digital temperature relay TR - 100 with three temperature sensors of the RT100 type built into the LV windings. For special transformers (for powering semiconductor converters, etc. ), and also at the request of the customer, an additional sensor is installed to control the temperature of the magnetic circuit. The temperature relay TP - 100, equipped with an RS - 485 MODBUS RTU interface, is connected to a constant or alternating voltage from 24 to 260 V. When the temperature rises dangerously, the output relay for controlling the alarm circuits is triggered. If the temperature continues to rise and the temperature exceeds the limit, the alarm output relay (transformer trip) will operate. At the request of the customer, other types of temperature control devices can be installed. Transformers TSL, TSDL (without a protective casing) are equipped with temperature sensors with a cable length of ten meters, which allows the thermal protection relay or fan control box for TSDL to be transferred to the enclosing structures or other structural elements of the substation (at a distance of up to six meters) to ensure its safe and convenient maintenance. Other types of thermal protection can be installed at the request of the customer. Transformers TSDL, TSDZL, TSDZLF, TSDZL11, TSDZLF11 are equipped with a forced cooling system consisting of a control box and winding cooling fans. The use of forced ventilation makes it possible to increase the power of dry transformers up to 40% .
