Description

USE OF MULTI-LAYER FLEXIBLE BAR PER PHASE AS CONDUCTOR FOR

POWER DISTRIBUTION

FIELD OF INVENTION

The invention relates to the use of multi-layer flexible bar per phase as conductor in prefabricated and modular busbar systems which are designed for the distribution and transport of electric power and In which low-medium voltage electrical distribution is carried out

STATE OF THE ART

Section of conductor and problem of cost relating thereto. Current-carrying capacity of the rigid bar conductors used in standard busbar energy distribution systems is lower than flexible bars. The leading cause of this difference is related to a condition which is known as skin and proximity effect (the fact that electrons do not use the section effectively due to their easier movement on the nearsurface area of the conductor as compared to nucleus) in the literature of electricity transmission. In that case, it is required to utilize larger sections in rigid bars than flexible bars to conduct electric power in same amperage which also increases the cost of conductor.

Another problem arising out of the large sections of conductor is related to the installation of end products on-site. Due to the fact that bar weights are above the weights that mounting operators can carry in busbar systems with rigid bar conductive materia! at high amperage, it creates difficulties in mounting and cost increase such as utilization of another machine or equipment.

Failure to obtain requested amperage with a single busbar box. As conductor sections enlarge in rigid-conductor busbar systems at high amperages, the sizes of busbar boxes exceed the acceptable and applicable values if the value exceed a certain amperage, it is only possible to obtain requested amperage by combining the busbar boxes. The larger busbar boxers increases the loss of volume in the areas where mounting process will be applied.

Due to the large size of busbar bars, the cost of product shipment is increasing,

The low current-carrying capacity of the rigid busbars used In standard busbar systems causes the increase of conductor section variances in amperage changes as well as increase the range of products, it also makes the standardization of product range difficult,

For the same reason, increase in the diversity of products means the increase in the inventory costs of the ma nufacturer.

The low switching, seismic and physical impact resistance of rigid bards are another important drawbacks of the currently existing standard busbar systems.

TR2013/i4804 Adjustable busbar suspension apparatus relates to a suspension apparatus involving a main body, rod assembly and binrak line so as to support, suspend and easily mount the busbars designed for electricity distribution at multistorey buildings and industrial facilities.

TR2G15/H978 Fiug-in type busbar; it is a busbar used for the protection of conductors in electricity transmission systems wherein horizontal body of busbar consists of a housing for integration with vertical body as well as a threaded part allowing the vertical body to engage in the said housing.

DESCRIPTION OF THE INVENTION

The said invention relates to the use of multi-layer flexible bar per phase as conductor in busbar energy distribution which has been developed so as to eliminate above-mentioned disadvantages and provide advantages for the technical field. One objective of the invention is to reduce the cost of conductor by enabling the reduction of conductor sections by 10-50% which are used for the busbar energy distribution. The reduction in conductor sections also enables the decrease in the weights of busbar boxes thereby producing easily mountable products on-site whose mounting costs are tower than busbar systems with standard rigid bars.

The reduction in the size of conductor sections enab!es the decrease of the sizes and weights of the finished products thereby facilitating the transport of end products.

The reduction in conductor sections enables significant volume gain in the areas where the said product is being used.

Thanks to the use of multi-layer flexible bar per phase, it is possible to reach upper amperage limits of busbar energy distribution systems with standard rigid bar by using 1^st or 2^nd type busbar boxes. Reduction of product types makes the standardization easier for different areas (planning, production and safes).

Reduction of product types also enables the reduction in inventory costs, Thanks to the invention, amperage increase may be possible with the small changes in conductor sections while it may be possible only with the increase of the amount of multi-layer flexible bars.

In this way, the production of multi-layer flexible bars per phase and mounting process of the products are easier than standard busbar systems by 50%. The section advantage of the mu!ti-iayer flexible bar system enables the upper amperage limit of invention to easily exceed the upper amperage limits of the busbar systems with standard rigid bars. Thanks to the demountable structure of the system connections, maintenance and repair time is short and they can be repaired and subject to maintenance works in the area where they have been installed.

The preferred embodiments of the invention relating to use of multi-layer flexible bar per phase as conductor in busbar energy distribution within the detailed description are non-limiting descriptions and intended only for the better understanding of the invention.

The main difference is that power transmission is carried out by means of multilayer flexible bare instead of the standard rigid bare in the busbar energy distribution systems

For the busbar systems with standard rigid bar, the products are manufactured in series between the certain amperage intervals because change in conductor sizes are great while the amperage increases (for example; one series up to 250 amperes, another series up to 800 series.) Because of the fact that it is possible to obtain higher amperages with the smaller conductor sections of the busbar system with multi-layer flexible bar per phase, variation in conductor section and number of variation is very rare and so it is possible to achieve large amperage intervals within the same series (similar product group). While it is possible to increase amperages by means of adding flexible bar in our busbar system with multi-layer flexible bar per phase, it may be generally possible with the change of section for the busbar systems with standard rigid bar,

One of the main differences of the invention is that all connections are demountable type.
