MVC-type unidirectional servicing assembly camera (medium-voltage camera). Designed for receiving, monitoring and protecting the electrical system from the 6/10 kV side in distribution devices with frequent switching operations. The design excludes the simultaneous execution of conflicting operations.
EDS-manufactured MVC cameras are an elite lineup of Prefabricated chamber of unilateral service , optimized in terms of dimensions, drives, input systems, and protection. In comparison to standard Prefabricated chamber of unilateral service , MVC offers increased reliability, durability, stability of operating parameters, and functional
informativeness. The application of our camera units allows for the elimination of power supply interruptions and the associated losses.
FEATURES OF THE TECHNICAL SOLUTIOMVC-TYPE PREFABRICATED CHAMN
- They are divided into input, linear, sectional, bus bridges and compartments with voltage transformers.
- In the relay compartment, ammeters, secondary circuit equipment, and protection circuitry are located. Electricity meters and meter connection terminals are placed on the doors of the main compartment. Observational windows are provided on the doors inside the chamber for monitoring the condition and operation of disconnect switches.
- In compartments without the use of vacuum circuit breakers and relay systems for power transformer protection, high-voltage fuses are installed.
- High-voltage capacitive voltage indicators and observational windows for monitoring the condition of disconnect switches inside the chamber are installed on cables in the incoming and linear compartments.
- Microprocessor-based protection terminals are used in medium-voltage networks.
- Power supply can be fed from above or below via cables, and the arrangement of busbars can be either above or below.
- The housing structure is fully welded with removable panels.
ADVANTAGES OF OUR SOLUTION
- Arc protection is ensured through compartmentalization, a closed bus system, division of high-voltage device compartments, and a cable compartment. The combination of bus system compartments and secondary circuit compartments when arranged in a row. The sections are combined in a common structure and fully coordinated with each other.
- Grounding disconnect switches with the ability to close the drive when the blades are engaged using a lock, inclusion blocking systems.
- Door locks have been modified to maximize personnel protection in the event of an explosion within the compartment during a short circuit. The mechanism is activated by a special key. Access to the switching operation by unauthorized individuals is prevented. The mechanism does not protrude beyond the dimensions of the chamber, saving space in compact installations.
- A roof is installed above the busbars to protect the working elements of the compartment from heavy contamination.
- Extremely high operational reliability.
OUR CAPABILITIES
- We reduce costs through rational placement of systems in a single enclosure.
- We shorten the lead time for urgent orders through dealer deliveries.
- The products are certified by IEC.
- EDS equipment has successfully passed explosion localization testing at the "VIT" Certification Center (Zaporizhzhia).
