Description

Connectors and busbar systems for busbar systems

technical field

The invention relates to a connector suitable for a busbar system and a busbar system. the

Background technique

The electrical distribution system can be configured as a busbar system. Busbar systems are used to transport and distribute electrical energy. Typical tasks of busbar systems are, for example, the connection from transformers to secondary distributors via the main distributor or the feeding of large loads. Usually the busbars of a busbar system are installed in a busbar box which prevents undesired electrical contact between the busbars and the surrounding environment. The busbar boxes usually have taps at which electrical loads and busbars can be contacted and thus fed. the

Up to now, busbar systems have only been able to be extended if already installed parts of the existing busbar system were switched on without load and without voltage before the extension busbar was installed. This is problematic when feeding in sensitive areas, such as computing centers or hospitals, since equipment connected there should not be disconnected from the feeding. For extensions, the last connection elements of conventional busbar systems had to be connected in a load-free and voltage-free manner, so that sensitive areas had to be isolated from the hospital or the computing center had to be shut down in a costly manner. Up to now, busbar systems have therefore only been able to be extended by means of the previous connecting elements or parts thereof when they were out of service. the

The connector suitable for a bus bar system includes two bolted joints and at least two side-by-side, air-insulated bus bars extending along the longitudinal direction, wherein the connector includes a bus bar for connecting to the Two connection positions on the bus bar system, the two connection positions are respectively electrically connected to the bolt connection part. The connector is characterized in that the bus bar has a hook-shaped first notch at the first end, and the notch is configured to receive the bolt of the first bolt connection part, wherein the bus bar is on its The second end portion is electrically connected to the second bolt connection, and wherein the busbar is configured to be between a closed position for electrical connection between the two connection positions and an open position for electrical connection between the two connection positions swing around its second end. the

It is advantageous here that the connector can be installed together when assembling the electrical distribution system and that, when expanding the electrical distribution system, further busbar elements can be connected by means of the connector without the existing distribution system having to be disconnected. run. The connector enables an expansion of the electrical distribution system without the need for a load-free and voltage-free connection of the previous distribution system. The cost of the connector is significantly lower than the cost of shutting down or shutting down the original electrical distribution system. the

The second screw connection can pass through a second slot in the second end of the busbar. The first screw connection can pass through the first slot in a closed position of the electrical connection between two connection positions. the

In another embodiment the connector is mounted in a busbar housing. It is advantageous here that the connector is thus electrically insulated from its surroundings. the

The busbar housing of the connector may include at least one window. It is advantageous here that the operator is able to optimize to control the connector. the

The busbar housing can also comprise at least two openings through which the two screw connections can be screwed or unscrewed. It is advantageous here that, for example, the screw connection can be screwed in the closed position of the electrical connection between two connection points without opening the busbar housing. the

In a further refinement, the connector includes a handle, which is designed such that the busbar can be swiveled therethrough. The handle may be substantially cylindrical in shape, extending at right angles to the busbar and operable at least on one side of the busbar. The handle can also be configured to be operable on both sides of the busbar. the

In a further refinement of the invention, the handle is designed to be latchable in an open position and/or a closed position of the electrical connection between the two connection positions. It is advantageous here to prevent unintentional or unauthorized manipulation of the connector. the

The connector according to the invention can be part of a busbar system comprising two further busbars which are each electrically connected to one of the two connection points. The busbars in the busbar system can be designed as air-insulated and/or as a sandwich system. the
