Company "Prisma Electric" made cabinets of relay protection of the reconstructed 330 kV substation
"Prisma Electric" took part in the reconstruction of the substation at 330 kV, in which specialists modernized relay control circuit.
Purpose of electrical cabinets–control of one (DCC1) or two (DCC2) disconnectors. The control cabinets are used for one single-pole disconnectors’ actuator: DCC1 sequentially opens and closes each of the three phases of the disconnector, DCC2 provides three-phase control for two disconnectors, simultaneously disconnecting and closing all phases switch.
Electric cabinets purposed for connecting secondary circuits ofoutdoor switchgear 35-750kV. In the cabinets are installedcircuit breakers forsupply and sectioning of blocking circuits. Clamps quantity – 120.
SHC-1 and SHC-2 is designed for heating circuit breakers and its drives with power of heaters up to 10kW on phase while simultaneously switched off drive and tanks.SHC-2 is designed for heating circuit breakers and its drives with power of heaters more than 10kW, also for feeding motor drives of circuit breakers and switchgears.
