USE/ADVANTAGE - Allows number of 220V loads to be connected to split 380V supply.

Description

The invention relates to an electrical installation system for home and workplace electrification.

So far it has been common practice for house electrification the electrical lines in plaster in the Pipes to be installed in building walls and then by many connection points from the cabling to the individual Pantographs. This wiring is labor-intensive and expensive. By the predetermined Connection points is often a later rewiring for desired sockets, light or device connections not possible or only with great difficulty.

Furthermore, in many recent times, is on or in the Wall and / or ceiling surfaces defined cable channels worked in the pantograph (sockets, switches u. Like.) are used, which with busbars in the Cable channels interacting adapters power supply receive. But this also includes cabling work required and a later change of pantograph or laying over multiple levels is difficult. Especially This disadvantage often occurs in offices, in department stores or Wholesale markets, in which there is a renovation from time to time takes place and here, despite the cable ducts a complex and manual routing and cabling is required.  

Workplace electrification continues to exist Disadvantages of the ever increasing power consumption and too little Electricity feed. Especially in offices where everyone Workplace with several electrical devices, such as computers, electric typewriters, electric calculators, etc. is equipped, can with the usual 220 V supply current-carrying phase can only be loaded up to about 3000 watts, so that the capacity for several connected in series Devices are not enough.

This would require a 380 V supply; is there however for the laying of the electrical lines and their Splitting into the normal 220 V circuits a specialist required what a time and costly assembly results. Also in the case of a work conversion or a later one Retrofitting to other power consumer devices is in turn a specialist is required.

The object of the invention is therefore an installation system for home and workplace electrification, in simple, inexpensive and low workload requiring a versatile, variable and anytime changeable and interchangeable laying, arrangement and Connection of power take-off points within one and several Allows level without electrical wiring work and versatile and also assembled by non-specialists and changed or converted and retrofitted as required can.

This object is achieved by the characterizing Features of claim 1 solved; who adhere to it subsequent sub-claims contain advantageous and beneficial further training in task solving.

The electrical installation system according to the invention works for a variety of electricity consumers with a distribution box, in  which is a 380 V power supply that the live phases in the distribution box of three 220 V Circuits are split and prewired. The Electricity is taken from each of the three pantographs Distribution box through coded connectors and has each 220 V circuit has its own coded socket, in which is just the special counterpart in the form of a plug Power take-off line fits, so that a phase confusion is excluded.

The 380 V split into three 220 V circuits with the coded plug-in connection results in a distinctive Power distribution system in which short circuits or missing Electricity consumption can be excluded. Even if one of the three 220 V circuits carry the other two circuits continue electricity.

The 380 V feed has a power draw for many connected electricity consumers created and is thus optimal for home and workplace electrification, because through splitting and pre-wiring and coded Plug connection a conversion and retrofitting without the help of a Expert can be done in a short time.

Furthermore, switches can be placed in the three 220 V circuits use that as manual or remote and contactless operable on and off switches, as timers, as Signal switch in the event of a circuit failure and much more can be trained.

An installation system is also part of EP 0 140 079 Intermediate plugs, installation box, assembled Cables with three- and five-phase plugs and flexible Connection lines for a variable installation design known.  

However, this system does not work with one Power supply splitting and not with a coded Plug connection, but with this system the electrical lines measured by a specialist and A suitable connector for the phase to be used are provided and attached; this is for the easy one and also by non-specialists at the Desired workplace retrofitting and retrofitting not suitable and can also be used for Phase determination errors occur. This well-known system does not result in effectiveness in the decrease in electricity consumption as the inventive idea in the characterizing part of the present Claim.

The electrical installation system according to the invention works continue with pre-wired socket boxes, pre-assembled electrical connecting cables and pre-assembled electrical distribution blocks and is on / in a rail system from in or on building walls fixable mounting rails or cable ducts adaptable and here within one or more levels.

The single or multi-pole, one or more circuits containing, pre-wired socket boxes and the Prefabricated connection cables have coded, interacting connectors, avoiding a Phase reversal only electrical in a phase-appropriate manner can be connected together, which is a big one electrical safety guaranteed.

The size of the electrification network to be created and the Number of power supply points used (socket boxes) is arbitrary and the cable connection can be five-pin or are split into three poles by a socket box to the other socket box or from a distribution block several pantographs (e.g. computer devices).  

The entire system can be assembled without screws in which the socket boxes and distribution blocks in / on the Cable channels are determined by the electrification network and the electrical connection through the coded Plug connection between connection cables and socket boxes or distribution blocks, so that this system from everyone Layers can be created electrically safely.

Furthermore, through pre-assembled components and commercially available cable ducts or mounting rails a large Variation in the arrangement of the power take-off points, at any time any change of location, retrofitting or conversion in simple and quick way possible.

The socket box is only in the cable channel to the other desired position set or one or more additional Socket boxes are inserted into the cable duct and then the socket box connection is made by longer or shorter, pre-assembled connecting cables in screwless Wise. All cabling work is eliminated.

Also normal socket boxes are due to the phase coding compatible with other socket boxes, so that a normal box can be exchanged for a special box.

This system also includes the arrangement of control lines possible for circuits.

This very simple and variable and because of the pre-assembled components and omitted Cabling work cheaper and in the shortest possible time Installation system that can be created or converted and retrofitted comparable to a normal house electrical system, but has it has a higher utility value.  

The system can be used in normal households, buildings, offices, installed in workshops on / in the existing walls are and is also for furniture and partition wall assembly in Living and working spaces, department stores, in schools, laboratories, Clinics, hospitals and municipal buildings in can be used economically and can be created efficiently.
