Technical Field

The invention relates to a pressure balancing device for busbars used in power distribution systems.

In particular, the invention relates to a pressure balancing device used in electrical distribution systems known as busbar to prevent deformation and to provide a homogeneous contact pressure when exposed to the torque forces applied during the mounting of the conductive bars in the housing to the additional connecting module.

Background of the Invention

In today's energy distribution systems, modular compact conductors called busbar are used. Each conductor called busbar is more preferred because it has structures with a high current carrying capacity.

Electrical distribution and transport systems known as busbar are modular. Each busbar module is attached to the end of the line according to the route of the electrical line and forms the electric transport line. The modules are connected to each other by means of the so-called additional module.

The busbar add-on module connects the conductor rods in the busbar modules electrically and mechanically to each other and allows the line to continue.

When the additional module is attached to said conductive bars, the tightening torque applied to each of the conductive bars is attempted to be compressed in each additional module. Initially, the conductive bars located in the cavities of the additional connection module begin to generate contact pressure to provide more compression and electrical conduction. However, the conductive bars are forced to deform with this compression and some of the applied compressive force is expended for deformation.

Therefore, the applied torque force is converted into contact pressure with a great loss. In particular, there are extra differences between the outer conductor bars and the inner parts resulting from the sequence. This leads to different and insufficient contact pressure in each contact housing of the assembled supplementary module. This prevents an ideal and healthy addition.

In the literature in the Chinese patent application CN106299751 , the invention provides a connecting device for insulating pipe type busbar ends. The device is a pressing plate device arranged between the insulating tube type busbars and arranged between the insulating tube type busbars, which comprises a ferrule used to meet the electrical property of the connection of the insulating tube type busbar ends two insulating tube-type busbar inserts and rings in a plane-plane contact or in a tube expander which flexes two insulating tube-type busbar ends. The insulation and electrical protectors of the joints of the insulating pipe type busbar are carried out on the shrinkage. By means of the pressing plate, the plane-plane connection of the isolation pipe-type busbar ends is performed and the contact area is increased. With the pipe expansion device, the connection of the insulation pipe type busbar ends is made and the corresponding contact pressure is increased. Breaking, internal connection and external connection are avoided.

In the said application, an insulating device for connecting the busbar ends is provided in an additional connecting device.

Again in the literature, the Chinese patent application CN204118632 states that a A busbar line bending unit joining connector can change directions when a busbar line unit is installed, and a combined insulating plate, an additional fixture, a copper rod and a right-angled steel clamp plate the occlusion of the holes. The isosceles triangular arrangement, wherein an additional linkage copper bar results in the current carrying portion allowing the temperature rise to pass. The two right angle sides of the right angular isosceles form a direction in which the busbar line unit is blocked at a right angle; a transient bolt is used and a disc spring pad pressure plate, a disc spring pad and a combined steel clamp plate can firmly press and secure the additional connecting copper rod with a busbar of the busbar line unit.

In the said application, the common connector assembly used at the twist points in the busbar units is described.

For the reasons mentioned above, there is a need for a new pressure balancing apparatus for busbars.

Purpose of the Invention

The object of the invention is to provide a new pressure balancing device which eliminates the existing disadvantages.

Another object of the invention is to provide a structure for the deformation of the busbar systems when the conductor bars are subjected to the torque forces applied during the assembly of the additional module.

Another object of the invention is to provide a structure that provides a homogeneous contact pressure in busbar systems.

Another object of the invention is to provide a structure that prevents the deformation of the conductors by allowing the deforming structures to act as a damper.

Another object of the invention is to provide a structure that minimizes the power losses on the conductor bars.

In this detailed description, innovation according to the invention is explained by examples which will not have any limiting effect on a better understanding of the subject.

The invention is a pressure balancing device to prevent deformation of the compressive strain of the conductive bars (1.1) located in the busbar module body (1.2) together with compression during assembly on the additional connecting module (3) in electrical distribution systems known as busbar; characterized in that comprises a pressure balancing apparatus (2) which is mounted on two open ends of said busbar module body (1.2) and prevent deformation due to displacement force (S) caused by additional module mounting torque (Q) and additional module mounting force (F) applied on said conductor rods (1.1) and providing a homogeneous contact pressure.

The pressure balancing device according to invention consists of main parts that; the busbar module (1 ) used in the electrical distribution systems known as busbar, the conductive bars (1.1 ), which are the part of the busbar module (1 ) providing the energy transmission, and the busbar module body (1.2) which protects the conductive bars (1.1 ) from external influences, a pressure balancing apparatus (2) which is mounted on two open ends of said busbar module body (1.2) and prevent deformation due to displacement force (S) caused by additional module mounting torque (Q) and additional module mounting force (F) applied on said conductor rods (1.1 ) and providing a homogeneous contact pressure, the flexing module (2.1 ) having a flexible structure, which is positioned on said pressure balancing apparatus (2) and prevents the formation of pressure on the conductive bars (1.1 ) by taking on said displacement force (S), additional connecting module (3) for connecting the said busbar modules (1 ) together with said conductor guide holes (2.2) positioned on said pressure balancing apparatus (2), which allow said conductive bars (1.1 ) to easily enter said pressure balancing apparatus (2). The additional module mounting force (F), which occurs when connecting said busbar modules (1 ) to each other via an additional connection module (3), provides the additional module mounting torque (Q). Said additional module mounting torque (Q) leads to the formation of displacement force (S) on the conductive bars (1.1).

The flexing module (2.1 ) located on the pressure balancing apparatus (2) according to the invention prevents the compression of the conductive bars (1.1 ) by taking the displacement force (S) on the conductive bars (1.1 ). Said flexing module (2.1 ) has a flexible structure. Said flexing module (2.1 ) absorbs the displacement force (S) by providing a spring-like extension.

In this way, it is prevented that the conductive bars (1.1) are deformed by being compressed.
