The control and protection cabinet is designed to install temperature measuring devices, control electric motors of cooling fans of the M / D type of power transformers, connect built-in current transformers and process protection sensors of transformer equipment of voltage class up to 1150 kV to relay protection and automation circuits (RZiA) monitoring systems or ACS TP of an energy facility.
The main functions of PCC:
- protection of each electric motor against short circuits, overloads, operation at high and low voltage, open circuit, asymmetry and violation of the phase sequence;
- transformer cooling system control;
- failure alarm of any fan motor;
- the ability to turn off the fan motors;
- connecting a backup power source to the PCC;
- microclimate maintenance in PCC;
- lighting in PCC;
- switching of wired cable communication lines with the equipment of relay protection and automation equipment, monitoring systems or process control systems.
