The terminal cabinet is designed for the installation of dial thermometers, the connection of built-in current transformers and sensors for technological protection of transformer equipment of voltage class up to 1150 kV to relay protection and automation circuits (REE) monitoring systems or process control systems of an energy facility.
TK corresponds to climatic modification U, placement category 1 according to GOST 15150-69 and GOST 15543.1-89. The climatic version of the internal equipment corresponds to the UHL version, placement category 3.1 according to GOST 15150-69 and GOST 15543.1-89.
The main functions of the bar:
- indication of oil temperature and power transformer windings;
- switching of wired cable communication lines with the equipment of relay protection and automation equipment, monitoring systems or process control systems;
- microclimate maintenance in the bar;
- lighting in the bar.
