MOSEC switchgear is a factory-assembled, typetested, three-phase, metalenclosed, indoor switchgear according to IEC 60 298 and VDE 0670 part 6 for single busbars systems.

Technical data:

• Rated voltages up to 24 kV
• Rated short-time withstand current up to 25 kA
• Rated normal current of feeders
  
  • Up to 630 A, e.g. for ring-main, metering and circuit-breaker panels
  • Up to 1250 A, for circuit-breaker and bus sectionalizer panels
• Rated normal current of busbar up to 1250 A

Typical uses

SIMOSEC switchgear is used for power distribution in distribution systems with feeder currents up to 630A.
Modular space-saving design allows use in

• Substations, customer transfer substations, distribution substations and switching substations of power supply and public utilities
• Public buildings, such as high-rise buildings, railway stations, hospitals
• Industrial plants

Typical examples

• Wind power stations
• High-rise buildings
• Airports
• Underground railway stations
• Sewage treatment plants
• Port facilities
• Traction power supply systems
• Automobile industry
• Petroleum industry
• Chemical industry
• Unit-type heating power stations
• Textile, paper and food industry
• Emergency power supply installation

Modular design

• Individual panels, for free combination and extension
• Option: Low-voltage compartments can be supplied in two overall heights

Technical features

• Gas-insulated, maintenancefree switching functions for the three-position switch
• Three-pole primary enclosure
• Phases arranged one behind the other
• No cross-insulation between phases
• Air-insulated busbar and cable connection system
• Three-position switch, metalenclosed, with air-insulated primary terminals and gasinsulated switching functions
• Vacuum circuit-breaker 3AH5, metal-enclosed, up to 630 A, fixed-mounted in gas-insulated switchgear vessel
• Vacuum circuit-breaker 3AH6, air-insulated, up to 630 A, easy to remove after loosening the fixing bolts.
• Hermetically-sealed by welding, stainless-steel switchgear vessel,

-    For switching devices
-    With welded-in bushings (for electrical connections and mechanical components)

• Pressure relief

-    To the rear and upwards
-    Separately for each compartment

• Air-insulated cable connection system for conventional cable sealing ends
• Three-phase current transformer, factory-assembled on the feeder bushings
• Integrated low-voltage niche (standard) for installation of, e.g.

-    Terminals, MCBs, pushbuttons
-    Protection devices
-    Option: Top-mounted low voltage compartment
-    Option: Panel heating for severe ambient conditions, e.g. condensation

Personal safety

• All switching operations can be performed with closed panel front • Metal-enclosed LSC 2 A or LSC 2 B panels
• HV HRC fuses and cable sealing ends are only accessible when the outgoing feeders are earthed
• Logical mechanical interlocking
• Capacitive voltage detection system for verification of safe isolation from supply
• Earthing of outgoing feeders by means of make-proof earthing switches

 

Busbar compartment

• Busbar
• Insulating cap (e.g. for Ur > 17.5 kV) on busbar
• Bushing-type insulator for busbar

Security of operation

• Components, e.g. operating mechanisms, three-position switches, vacuum circuitbreakers proven for years
• Panels (metal compartmentalization (metal-clad) between busbar and switching device and between switching device and cable connection compartment)
• panels with metal compartmentalization between switching device and Cable compartment
• Three-position switch metal enclosed with gas-insulated switching functions

-    Welded sealed-for-life switchgear vessel
-    No cross-insulation between phases
-    With welded-in bushings for cable connection, busbar and operating mechanism

• Switch operating mechanisms outside switchgear vessel
• Maintenance-free operating mechanism parts VDE0670 part I1000/IEC60694
• Mechanical switch position indications integrated in mimic diagram
