Benefits and Features

Standards

The circuit-breaker switchgear type SIMOPRIME is a factory-assembled, type-tested switchgear for indoor installation according to IEC 62271-200 and VDE 0671-200.

Classification of the SIMOPRIME switchgear according to IEC 62271-200

Design

Compartments
Switching-device compartment

• All switching operations with high-voltage door closed
• Pressure relief upwards
• Panel powder-coated with epoxy resin
• Shutter operating mechanisms separately for
  • Busbar compartment
  • Connection compartment
• Metallic, earthed shutters and partitions ensure partition class PM
• High-voltage door pressure resistant in the event of internal arcs in the panel
• Metallic ducts on the side for laying control cables
• Interlocking between high-voltage door and circuit-breaker truck ensures interlock-based access
• Option: Test sockets for capacitive voltage detecting system

• Switching-device compartment to accommodate components for implementing various panel versions with
  • Vacuum circuit-breaker with or without voltage transformers on the truck
  • Disconnector truck
  • Vacuum-Contactor truck
  • Metering truck

RahimiBusbar compartment

• Pressure relief upwards and through rear pressure relief duct
• Option: Busbar transverse partition between panels
• Busbars made of flat copper, bolted from panel to panel
  • For rated normal currents up to 3600 A
  • Option: Insulated busbars
• Bolted rear and top covers provide tool-based access
• Option: Coupling electrode for capacitive voltage detecting system
• Options: Possibility of installing the following components
  • Voltage transformers
  • Busbar earthing switch
  • Current transformers in the run of busbars
  

Connection compartment

• Pressure relief upwards through rear pressure relief duct
• Suitable for connection of
  • Single-core XLPE cables up to max. 6 x 500 mm2 per phase
  • Three-core XLPE cables up to max. 3 x 300 mm2 per panel
  • Bars made of flat copper with bushings in a floor cover or fully-insulated bars including floor cover
• Shutters to be opened separately to permit cable testing
• Earthing busbar
• Connection from front or rear
• Option: Pressure-resistant floor cover
• Use of ring-core or block-type current transformers
• Bolted rear covers of the connection compartment provide tool-based access for panels with connection from rear
• Interlocked high-voltage door and bolted partitions between connection compartment and switching-device compartment provide interlock- based and tool-based access for panels with connection from front

Low-voltage compartment

• For accommodation of all protection, control, measuring and metering equipment
• Partitioned safe-to-touch from the high-voltage part
• Low-voltage compartment can be removed, bus wires and control cables are plugged in
• Option: Partition between panels

Interlocks

• Interlocking conditions are satisfied according to IEC 62271-200 / VDE 0671-200
• Earthing switch can only be operated with circuit-breaker truck in test position
• Circuit-breaker truck can only be moved with circuit-breaker “OPEN” and earthing switch “OPEN”
• Mechanical coding on the circuit-breaker truck prevents insertion of similar circuit breaker trucks for lower rated normal currents into panels with higher rated normal currents
• Interlocking of high-voltage door against circuit-breaker truck
• The high-voltage door can only be opened when the circuit-breaker truck is in test position
• Option: Electromagnetic interlocks
