24kv Panel Sliding Model

Technical Expertise

The technical knowledge for manufacturing 24kV withdrawable medium-voltage switchgear type AMS has been developed through a joint collaboration between Mehrabad Industrial Company and German specialists, based on the requirements of the IEC62271 standard. It has successfully obtained type-test certification from the ICMET laboratory in Romania.

Features and Benefits

This switchgear offers a diverse range of current and voltage ratings, compact dimensions, and a reinforced structure using DOUBLE BENDING technology. Its ease of operation makes it an ideal choice for various industrial projects, sub-transmission stations, and power plant applications.

Key Components

  • FDV3 Series Withdrawable Breaker:Equipped with a third-generation vacuum breaker with EMBEDDED POLE technology, it allows for interchangeability between similar feeders.
  • High-Speed Ground Switch: The ground switch operates quickly and independently of the operator's speed. It includes a capacitive divider, electrical and mechanical status indicators, and various electrical and mechanical interlocks.

Safety Interlock Systems

The design of the switchgear's interlock systems comprehensively addresses safe operation and equipment protection, ensuring the following:

  • Locked-Closed Prevention: The breaker cannot be moved while in the closed position.
  • Test/Service Positions Only: The breaker can only be connected in the test or service positions.
  • Interlock with Door: The breaker can only be moved from the test to the service position (or vice versa) when the breaker compartment door is closed.
  • Ground Switch Interlock: The breaker cannot be moved from the test to the service position if the ground switch is closed.
  • Service Position Interlock: The ground switch cannot be closed if the breaker is in the service position.
  • Cable Compartment Interlock: The cable compartment door cannot be opened unless the ground switch is closed.
  • Control Connector Interlock: The control connector cannot be detached once the breaker is in the service position.
