Description

Hybrid power supply bus, bus plate and power supply system Technical Field The invention relates to a hybrid power bus, a bus plate and a power supply system, which can provide selection of back power supply while various electric devices are installed on the front surface. Background A power supply system for distributing power among electrical devices is typically installed in a control cabinet. Examples of electrical devices include switching means and switching elements, such as contactors, fuse elements or even display units, which may for example indicate the operational status of a downstream electrical utility. The control cabinet has a limited internal space and is therefore costly, especially in areas where the user can install electrical equipment. In a conventional control cabinet, the power feed of the power supply is performed by a power supply module arranged on the front side of the bus bar. The disadvantage of this design is that the space required for the front side power module cannot be used for other busbar components. EP 4 184 A1 describes a back-side power supply module for a distribution busbar system. Disclosure of Invention The object of the present invention is to improve existing power supply systems, in particular in terms of flexibility and compatibility of use, simplicity of design and operational performance. The above-mentioned problems are solved by the subject matter of the independent claims. Thus, according to a first aspect of the present invention, there is provided a hybrid power bus comprising: a first type of connection portion having a plurality of regularly arranged sockets for receiving electrical and/or mechanical interfaces of electrical devices of a first connection type from the front face of the power bus bar by selection (in particular, arbitrary selection) of (at least) the sockets; A second type of connection portion having a front contact portion located on the front side of the power bus bar and a rear engagement portion facing away from the front contact portion, a first electrical and/or mechanical interface for an electrical device of a second connection type engaging the rear engagement portion while a second electrical and/or mechanical interface thereof contacts the front contact area, and A rear power coupling portion extending from the second type connection portion and facing away from the front face of the power bus bar for receiving a feed-in current at the rear face of the power bus bar for powering the power bus bar and/or for providing a feed-out current at the rear face of the power bus bar. The electrical device of the first connection type and/or the electrical device of the second connection type may be any of a fuse holder, a fuse switch disconnector, a fused switch disconnector, an adapter for an MCB or an MCCB or a motor starter or contactor, a power supply, a motor starter, a surge protector and other electrical and/or electronic devices. The term "hybrid power bus" or "hybrid bus" refers to the compatibility of a power bus with electrical devices of a first connection type and with electrical devices of a second connection type, as opposed to a conventional "non-hybrid" power bus that is configured to be compatible with only one or the other if an adapter is not used. The electrical and/or mechanical interface for receiving an electrical device of the first connection type by selection of (at least) slots refers to the fact that typically each electrical device (e.g. an adapter, a switching element, etc.) will occupy only some of the slots, the main purpose of the bus bar being to provide power to a plurality of devices. It should be appreciated that in general, any electrical device may be installed with any slot chosen. In some variations, it is preferred that the front face (or: mounting side, or: mounting surface) of the power bus be as regular as possible, thereby providing the user with maximum flexibility as to where to mount which electrical devices. The front face is so designated because typically the power bus bar (e.g., within the bus bar plate) will be mounted with its back face on a wall or mounting plane and its front face on the front face, with user access to mount and dismount electrical equipment. With respect to the electrical device of the second connection type, it should be understood that when such a device is mounted to the power bus, the first electrical and/or mechanical interface and the second electrical and/or mechanical interface of the same device simultaneously contact the front contact portion and the rear engagement portion, respectively. In general, any of the first and/or second mechanical interfaces may be electrical and mechanical, purely electrical or purely mechanical, although typically at least one interface of any device will have at least electrical functionality. An electrical interface (or: an interface with electrical functionality) means that the interface is capable of receiving el
