The high-voltage cathodic protection unit UKZV is created to receive three-phase current energy with a frequency of 50 Hz at a nominal voltage of 6 (10) kV, transform it into a nominal voltage of 0.23 (0.4) kV and distribute it over power grids. with solidly grounded neutral for cathodic protection converters and automatic reinforced drainage stations
Purpose
A high voltage cathodic protection unit UKZV (MEKhZV) is used to prevent damage of underground metal structures by galvanic corrosion. Power transmission lines with a voltage of 6, 10 kV and a frequency of 50 Hz are used as a power supply for the MEKhZV module. The equipment is connected by means of air disconnectors and inlets.
It complies with the requirements of GOST 14693, GOST 1516.1, GOST 1516.2, GOST R 51321.1, OTT-29.100.99-KTN-035-19, TU 27.12.31-090-73892839-2018 and design documentation for the device production.
The device is manufactured in U (moderate), UKhL (moderately cold climate) (Khl- cold climate) climatic versions on the basis of GOST requirements. It is intended 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.
Additionally, at the customer's request, the UKZV can be equipped with a telemechanic system, alarm devices (door opening sensors connected or not connected to the telemechanic system), joint protection units BSZ (Diode Resistive Units BDR (M)), Emergency Redundancy Units BAR, Heavy-Duty Drainage Protection Devices (SAUD), heating systems and other equipment.
The total power of the transformer rectifier and other low-voltage equipment located in the device shell shall not exceed the rated power of the high-voltage power transformer.
The UKZV is completed with a single-phase transformer of the OMP or OMG type. At the request of the Customer, the device can be equipped with a three-phase transformer of the oil-filled waterproofed type. The device has the ability to manually and automatically control the protective potential.
Depending on the seismicity of the location area, they can be manufactured in three versions:
- earthquake-resistant (С);
- increased earthquake-resistant (IER) for areas with seismicity up to 10 degrees inclusive.
