Low Voltage Distribution Cabinet
Intended Use
The PSS-LVDC Low Voltage Distribution Cabinet is designed to receive three-phase electrical energy with a frequency of 50 Hz at a nominal voltage of 0.23 (0.4) kV and distribute it in electrical networks with a solidly grounded neutral to transformer rectifiers and automatic reinforced drainage stations to protect metal structures from corrosion.
The PSS-LVDC provides voltage transmission of 0.23 or 0.4 (± 10%) kV for cathodic transformer rectifiers (TRU) and other additional equipment. The device provides placement of composite equipment: transformer rectifiers with up to six stations and other low-voltage equipment - joint protection units, diode resistive units up to five pieces, and drainage protection devices up to five pieces at the customer's request. The device has the ability to manually and automatically control the protective potential.
Additionally, at the request of the customer, the Low Voltage Distribution Cabinet can be equipped with a telemechanic system, alarm devices (door opening sensors connected or not connected to the telemechanic system), emergency redundancy units BAR, heating systems and other equipment.
The device is manufactured in moderate, moderately cold climate and cold climatic versions. It is designed for permanent outdoor installation. The use of the unit contributes to the reliable stable operation of the equipment, regardless of the influence of atmospheric and climatic factors.
Depending on the seismicity of the location area, they can be manufactured in three versions:
- Non-earthquake-resistant (С0)
- Earthquake-resistant for areas with seismicity up to 6 degrees inclusive
- Earthquake-resistant (С) for areas with seismicity from 6 to 9 degrees inclusive
- Increased earthquake-resistant (IER) for areas with seismicity up to 10 degrees inclusive
