PPA ENERGO s.r.o.

PPA ENERGO s.r.o. is the largest subsidiary of the PPA CONTROL holding. It is mainly focuses on nuclear power engineering. Currently, it is largely contributing to the completion of Mochovce nuclear power plant - EMO 3 and 4.

Focus of activity

It offers comprehensive services in the area of: Automated control systems, field instrumentation and electric systems for conventional and nuclear power engineering, which can be divided into the following categories:

Production of switchboards

  • 0.4KV LV SMO switchboards (Rittal, Sarel, Profiline, Schrack boxes)
  • 0.4 KV LV switchboards for nuclear power plants (SMO-S, SBO, NRS-S)
  • RVB modular switchboards with sliding blocks (Logstrup boxes)
  • System switchboards for control systems, servers and PCs
  • Industrial and data communications switchboards

 

  • Compensation switchboards
  • Wall-mounted NRS and NRS-P switchboards
  • Control room panels and desks
  • Traffic signs

Modular RVB switchboards can be used mainly in applications with continuous operation or in places where maximum emphasis is put on the system functionality with the shortest possible time of removing any eventual faults, without shutting down the entire switchboard.

Use of RVB switchboards:

  • Power engineering (also with the need for increased resistance to seismic events)
  • Industry
  • Technological equipment of buildings
  • Food and chemical industries

Safety:  

  • system of protection against electric arc (exhaust flaps over the main bus system, exhaust of gas from fixed and withdrawable units, partitions between fields, additional locks on doors and so on),
  • blocking of withdrawable modules against pull-out in the switched-on state,
  • test positions of modules
  • internal protection of switchboard even in the removal of withdrawable units is IP20,
  • internal segregation

Electrical parameters:

Rated operating voltage (Ue) 690 V AC
Rated insulation voltage (Ui) 1,000 V
Rated frequency 40-60 Hz
Main horizontal buses
Rated current (In) 8,500 A
Rated short-time current (Icw) up to 130 kA/1 sec.
