SYSTEM DESCRIPTION

SERVICE & SUPPORT

The low voltage switchgear combination ONS 5.1, made by OHMEGA Energy GmbH, with its comprehensive extension options and fixed-mounted, plug-in and withdrawable technology designs, represents a modern and future-proof solution for a wide variety of application areas.

The modular system design enables diverse combinations for project-specific requirements, configured as type-approved low voltage switchgear combinations in compliance with IEC 61439-1/-2 and EN 61439-1/-2.

The types of panel configurations ensure secure spatial division into busbar, device and cable compartments. The formation of electric arcs is almost completely prevented through constructional features, any arcing faults are spatially restricted through the modular structure and are rapidly eliminated.

It is possible to design the switching panels with an inner subdivision ranging from Form 1 to Form 4 b, where Form 4b offers the maximum operating safety and optimal personal protection for the operating personnel.

MCC FULLY WITHDRAWABLE TECHNOLOGY UP TO 630 A

PRINCIPLE OF SWITCHING

The technical principle behind the contact module with regards to the power contacts is ”switching” and not the standard ”plug-in”. There is no material fatigue as is the case with plug contacts. The main advantages of this system are based on this. The switching contacts of the contact module can contact the distribution bars and the cable connection module in the ”Operation” position when the control plug is extended. The switching contacts of the contact module are pulled back in the ìDisconnectedî position. The fully withdrawable module can then be pulled out of the device compartment.

PROTECTION AGAINST INCORRECT OPERATION

Protection against incorrect operation provided by secure locking mechanisms. For instance, the operating slider for the contact module is mechanically interlocked with the main switch, the contact module can only be switched when load-free. It is not possible to open the switch cabinet module door when the contact module is switched on.

INTELLIGENT CONSTRUCTION

The distribution bar is integrated in the system wall between the device and cable compartments. A design without base points ensures arc fault-protection through the complete insulation and additional subdivision of individual conductors.

Shutters only release the contact surfaces of the distribution bars and the cable connection module for contacting when the fully withdrawable module is pushed in. This ensures IP20 contact protection, irrespective of the module configuration.

The size and function of the fully withdrawable modules can be combined as required according to project requirements. Conversion is possible during ongoing operation without switching off. Two 6 U fully withdrawable modules can be replaced, e.g. by a 12 U fully withdrawable module.

Panel widths (mm) 1000 / 1200 (cable connection compartment 400 / 600 wide)


The busbars or modules are mounted on vertical distribution bars. The outgoing terminals of the power and control cables are connected directly to the devices. Standard types are available for customising the power distribution sectors, e.g. switch variants and Motor Control Center (MCC). Customer-specific modules can be added for special technological requirements.

ADVANTAGES

Flexible, modular design and therefore cost- efficient space utilisation of the outgoing panels

The compensation panels can be expanded by standardised modules with unchoked/choked capacitors and a control module.

The distribution bar is supplied via cable or via direct contacting with the main busbar.

The panels are equipped with a temperature-controlled fan for greater compensation powers. The fan is controlled via the control module.

Optionally, the compensation panels can be designed so that an arc-proof barrier is ensured between the busbar and device compartment.


IN-LINE SWITCH CABINET FOR CUSTOMER-SPECIFIC MODULES

PROPERTIES Type of installation Permanent technology

Power range up to 1600 A

Device brands Freely selectable


Panel widths (mm) 400 / 600 / 800


The switch cabinets for customer-specific designs can be planned and created for special and application areas with a range of design options.

Control panels for measurement and control systems can be easily integrated in the overall system. It is possible to upgrade with 19“ swing frames or use mounting plates for this purpose.

These panels can be equipped for power distribution with e.g. NH and D fuse elements, circuit breakers and other safety and switching devices.

Once again, there are no limits for panel expansion with regards to the applicability of switching devices from all known manufacturers.
