Description

TECHNICAL AREA

The invention relates to the support and insulation of conductive busbars that transmit electrical current in low-voltage power distribution boards.

The invention relates in particular to ensuring better absorption of static and dynamic loads by means of support by an insulator which surrounds conductive busbars from four sides, and also relates to the modular design of a busbar support insulator by constructing holding parts so that they are separated from height parts .

CURRENT PRIOR ART

Currently, conductive busbars are supported in current applications of parts made from non-conductive materials. There are too many types of applications. In some applications, all poles that conduct electricity are supported by a single insulator, in some cases a separate insulator is used for each pole. In some applications, insulators used for support vary depending on the size of the conductor, while in other applications a single type of insulator is used for all sizes. The cost of insulators, which vary according to the size of the conductor, can be high because they require too many different models.

The utility model with the application number TR2013 / 10658 relates to a busbar support insulator of a single type that does not vary depending on the dimensions of the conductor. This method reduces costs, but insulators of this type can only be used on the bottom and top of the conductor (no connecting part between bottom and top), and therefore the resistance is lower compared to other insulators. Furthermore, in this type of insulators, when the lower and upper parts are started to be firmly connected, the insulator tends to bend, and therefore a conductor cannot be sufficiently fixed in the middle of the successive conductors, and also Insulators deformed due to over tightening.

The utility model with the application number CN206820323 relates to a plan for placing busbars in a power distribution panel. This application is developing a solution to support busbars, but no solution to the durability of supports is offered.

The utility model with the title "Main Switch gear assembly system and procedure" and the number TR2012 / 11390 contains the following statement in summary: A vacuum-insulated main switch and main switch elements activated for it are equipped with a mechanically isolating rigid support arrangement without reinforcing or isolating winding against axial loads equipped for use with vacuum isolators. An insulating housing made of elastomer and / or the support arrangement is in contact with the outside of the insulator. A system and procedures for mounting the main switch are provided.

Furthermore, in current applications, isolators are designed so that they only support a conductive busbar and isolate them from a cross member where it is attached. No solution is proposed to isolate the start and end points of a conductive busbar at the beginning and end of the board from the board.

In summary, there have been developments in busbar supports and therefore new embodiments are needed which overcome the above drawbacks and offer solutions to existing systems.

PURPOSE OF THE INVENTION

The present invention relates to a modular busbar support insulator that meets the above-mentioned requirements, overcoming all of the disadvantages and providing some additional advantages.

The primary purpose of the invention is to provide a modular system for supporting conductors. An insulator that surrounds a conductor from four sides is modularly designed in such a way that holding parts and height parts are separated. Support of the conductor can thus be ensured by using different height parts or different holders if the size of the conductive busbar changes. In this way, a single product for busbars of different sizes can offer a more economical solution.

To make supports more durable, metal profiles are provided between brackets and height parts. Therefore, the connection between the bracket parts and the height parts is very stable, and the system integrity is ensured. The resistance of the supports to static and dynamic loads is also increased.

According to the invention, the busbar holder parts and height parts have channels for inserting insulating curtains to isolate start and end points of busbars from the panel. Insulating curtains are inserted into these channels and a dangerous approach of the busbar to the side surface of the panel is prevented.

The structural and characteristic features and all advantages of the invention can be better understood from the figures mentioned below and the description given with reference to the figures. Therefore, the evaluation should be based on the figures and taking into account the detailed description.

The holder parts ( 1 ) ensure alignment of the ladder at fixed positions and fastening it. There are busbar housings ( 8th ) are provided, which face each other on mutually facing surfaces of holder parts ( 1 ) and wherever conductors are to be arranged. Height parts ( 2nd ) that are selected so that they match the height of the busbar housings ( 8th ) to be used, are between the holder parts ( 1 ) arranged. Support housing ( 7 ) are opposite each other on the two facing surfaces of holder parts ( 1 ) arranged. Height support parts ( 3rd ) in cylindrical form in the support housings ( 7 ) by passing through the height parts ( 2nd ) are inserted through and fix holder parts ( 1 ) to each other.

A holder part ( 1 ) selected that is suitable for the type and size of the conductor to be used. If required, holder shapes ( 4th ) that match the types and sizes of the conductor to be used in the holder part ( 1 ) used. Then the height part ( 2nd ), which is required according to the types and sizes of the conductor to be used, and selected on the modular holder part 1 ) put on.
