The relay protection and automation equipment of primary equipment of this voltage class is characterized by: the use of main and backup protection of lines and transformers, the use of circuit breakers with a three-phase and phase-by-phase drive, a variety of connection schemes (two circuit breakers on the connection; with a bypass, sectional or bus-connection switch; bridge circuit in various modifications ) and etc. 330 - 750kV The primary equipment of substations with a voltage of 330-750 kV is intended for the transformation and transmission of electricity over long distances. For relay protection and automation of primary equipment of this voltage class, the following are characteristic: the use of two sets of basic protections, the use of circuit breakers with a phase drive to ensure emergency shutdown and subsequent switching on of one damaged phase of the transmission line, various connection schemes (two circuit breakers on the connection, one-and-a-half, "American" circuits), the need fire extinguishing systems, etc. Emergency automation A series of PA microprocessor cabinets of the SHEE22X type is intended for use as local and general station emergency control systems for substations with a voltage of 110-750 kV. SOPT (Operational DC System) SOPTs are designed to provide power supply to protection terminals, emergency control systems, automated process control systems, emergency lighting units, control circuits for switching devices, automation and signaling in normal modes and for two hours with complete de-energization of the substation's AC auxiliary needs. ShchSN (Auxiliaries) ШСН-0,4 series ШНЭ 8350 are intended for power supply of auxiliary needs of substations and power plants with alternating current voltage of 380 V and frequency of 50 Hz.
