The aforesaid guarantees, the high quality and safety of the switchgear while maintaining competitive pricing of the final product. Concurrently the Management of the Company is planning to expand the licensing agreement to include new typical product lines.

The SIVACON switchboard is a type – tested (TTA) low-voltage switchboard, which can be used as a main or alternatively as a distribution switchboard of electrical energy. The SIVACON switchboard is a product of SIEMENS Corporation and Regula Kosice – Joint Stock Company, subsequent to purchase of the license, acts as a “SIVACON Technology Partner”. Because the switchboard can be part of various technological processes (generation of heat, steam, electrical energy; production of steel, glass, chemicals; extraction of gas, coal and etc.), it is therefore considered as a Class “A” electrical equipment.

Modular Technology

Each SIVACON is grouped from standardized and type marked modules. All modules comply with Siemens construction specifications.

The modular technology facilitates optimal adaptation of SIVACON to any requirements.

Standard horizontal busbars are located on the top of the cubicle.

Depending upon requirements it is possible to separate functional units (form 1 to 4 in accordance with IEC 60439-1).

Instrumentation compartments are sufficiently deep.
It is possible to mount the switchboard on the wall or as free standing.
Cables and busbars can be lead-in from the top or from the bottom.
Cable tray compartments are located, either in the front or the back.
Good access to busbars is assured.

Frame and Covers

The frame consists from solid steel plate sections, which are joined together. Dimensionally exact and solid SIVACON frame is available, either, in bolted or welded versions. The frame is perforated by series of 25 mm holes to facilitate individual installation.
The door system is flexible for all needs.
Opening angle of the doors is up to 180°.
Spring-loaded locks safely protect the door from accidental or unintentional opening.
The upper covers are designed with the possibility of pressure release.

Surface finish:

There are options of powder layer, wet coating or galvanic metal plating.

Type- tested switchboard (TTA)

SIVACON is a type-tested switchboard (TTA). Its physical characteristics were designed in the rest laboratory for normal running conditions and for faulty situations. Final type testing provide the highest operating comfort and with optimal personal safety.
SIVACON has been verification tested in accordance with IEC 60439-1, DIN EN 60439-1 (VDE 0660 part 500):

Type testing:

  • Temperature increase limits verified by tests
  • Dielectric property verification by tests
  • Resistance against shorting verified by tests
  • Effective connection between unprotected conductive parts of the assembly verified by control or by measuring resistance
  • Resistance of the protective circuit against shorting verified by testing
  • Verification of tolerance and distances
  • Degree of protection verification

Each and every switchboard undergoes a usual running test prior to delivery:

  • Assembly check-up, including distribution and if necessary also production tests
  • Dielectric tests
  • Checking of the safety measures and electric connections of protective circuits

Safety requirements for SIVACON switchboards are guaranteed by series of details such as:

  • During the construction of withdrawable circuit breaker any running faults are solved by exact shaping of mechanical guides and locks
  • Use of only a few and particularly high quality materials (for example for busbar brackets, reinforcements and etc.)
  • Safe and dependable disconnection after between 70 ms and 100 ms, even in situation when a high time lag of 400 ms is set. This is achieved through 3WN disconnecter with regulation of short term grading
  • Computerized configuration assures trouble free selection and arrangement of items
  • Effective quality control

Proposal and production of SIVACON switchboards in CAE – CAD regime

Proposal and production of SIVACON 8PT switchboards has a huge support from the SIMARIS SIVACON software. The program works on the basis of a dialog between the executor and offered options for solution. The forerunner to the actual proposal by means of SIMARIS SIVACON is the evaluation of customer requirements in accordance with the following:

  • initial output of the equipment and the manner of feeding, and
  • character of exits, for example main lead-out for feeding of the sub-switchboard, motor lead-out or customer solved lead-out with given required output.

Based on the carried out order evaluation, SIMARIS SIVACON facilitates the following:

  • switchboard selection base don required output and current, instrumentation selection and type-tested modules, and
  • placement of modules into individual fields of the switchboard.

Subsequent to processing of the given data, the program makes available the following documentation:

  • frontal view of the switchboard with relevant number of fields including their setting, whereas there is also a possibility of processing the said in AutoCad program, and
  • bills of quantities for the mechanical construction of the switchboard, consisting from the frame and covers.

SIMARIS SIVACOM also provides cost calculation, by exploitation of its own data base regarding to production and erection costs and also makes it possible to transpose cost data of electrical instruments from other manufacturers.

 

Production of Modules and Dividing Interfaces

  • module production for cubicles of transmission relays
  • development and production dividers for solution of communication problems between various control systems.
