The terminal cabinet is designed for installation of pointer thermometers, connection of built-in current transformers and process protection sensors of transformer equipment of voltage class up to 1150 kV to relay protection and automation (RP&A) circuits of monitoring systems or APCS of power facility.
The cubicle corresponds to climatic modification Y, placement category 1 according to GOST 15150-69 and 15543.1-89. Climatic modification of the internal equipment corresponds to the execution "UHL", placement category 3.1 according to GOST 15150-69 and 15543.1-89 national standard.
Main functions of the EA:
- indication of values of oil and power transformer winding temperature;
- switching of wire cable lines with equipment of relay protection, monitoring systems or automatic process control system;
- Auxiliary room climate;
- lighting in control cabinets.
