Description

Technical area

The present invention relates to a kit for the assembly of main frames of circuit breakers with different sizes, in particular of circuit breakers of the extendable type in the medium voltage range.

State of the art

Circuit-breakers are provided with a main frame supporting the electrical equipment suitable for implementing the functions performed by the circuit-breaker itself. The main frame of the circuit breaker may have different sizes and / or shapes depending on the characteristics of the circuit breaker.

1 shows three examples of a main frame for three different power switches according to the prior art. The three frames 101 ', 101 "and 101'" have different sizes and shapes. Each of these frames has a first side wall 102 ', 102 ", 102"', a second side wall 103 ', 103 ", 103'", and a plurality of connectors 104 ', 104 ", 104'", which typically weld together are. In the first place, the three frames 101 ', 101 ", 101'" differ from each other in terms of the sizes of the connecting elements 104 ', 104 ", 104'", but the respective first 102 ', 102 ", 102'" and second differ Side walls 103 ', 103 ", 103'" also in shape and size from each other.

Therefore, for each size of the circuit breaker different side and connecting walls are needed, this means high manufacturing, transportation and storage costs.

Short Summary

Therefore, it is the object of the present invention to provide a kit for the assembly of main frames of circuit breakers of different sizes and / or shapes, to make it possible to simplify the manufacturing, transportation and storage processes, thereby enabling the associated costs reduce.

These and other objects are met by a kit for the assembly of main frames of circuit breakers of different sizes according to claim 1.

Detailed description

Referring to 2 to 3 denotes reference numeral 3 a circuit breaker and reference numerals 5 denotes a control console. The circuit breaker 3 may be, for example, of an extendible type and in the control console 5 be accommodated. For example, the circuit breaker 3 a slide rail 4 have, for example, wheels 7 along a connecting / disconnecting direction CD from an extended position with respect to the control panel 5 ( 1a ), in which movable contacts 2 of the circuit breaker 3 from the respective stationary contacts 6 the control console 5 are separated, to a Einbringungsstellung in the control console 5 ( 1b ), in which the moving contacts 2 with the respective stationary contact 6 are connected, is movable.

The extraction position corresponds to a mechanical and electrical separation position, while the insertion position corresponds to a mechanical and electrical connection position.

At the in 2 to 3 embodiment shown are the power switch 3 and the control console 5 of a Mehrphasenart, in particular three-phase. Therefore, each of them has three pairs of corresponding terminals. However, according to alternative embodiments, the power switch 3 and the control console 5 in this case, each of them has a single pair of corresponding terminals.

The contact elements 1 can with any of the moving contacts 2 be connected and are configured to work with the stationary contacts 6 the control console 5 to be engaged. According to the illustrated embodiment, the contact elements 1 of the tulip type. Alternatively, they can be of a different type, for example, you can be of the pliers type.

The circuit breaker 3 has a main frame 8th carrying the components mentioned above and also all the instruments and equipment needed for its operation. The frame 8th can be according to the size of the load switch 3 show different sizes and / or shapes. A kit according to the present invention allows the frames 8th and consequently the circuit breakers 3 different size, to assemble.

4 to 5 Figure 3 shows three examples of a main frame of three different circuit breakers obtained by the kit according to the invention. The three frames 8th' . 8th" , 8 '"show different sizes and shapes Each of these frames has a first side wall respectively 9 ' . 9 " , 9 "'and a second side wall 10 ' . 10 " , 10 "'on and one or more fasteners 11 ' . 11 " , 11 '"inserted between the side walls 11 ' . 11 " , 11 '"differ from each other, in particular they differ in their sizes and / or their shape, since they are intended to form a frame of a circuit breaker of a certain size., Opposite are the first side walls 9 ' . 9 " , 9 '"all identical to each other, accordingly, the second side walls 10 ' . 10 " '10''are identical to each other and each of them is shaped to engage with each of the fasteners 11 ' . 11 " , 11 '"can be connected, regardless of their arrangement 8th' . 8th" 8 '' of another frame of a different size only by its connecting element, which is specific to the size, while the first and second side walls are equally associated with each frame of each size.

In the kit according to the invention, the first side walls, the second side walls and the connecting elements are provided separately from each other, then they are mounted depending on the desired size of the main frame. For example, the connecting elements connecting flanges 12 have, to which the side walls lie directly, which may therefore be connected by connecting elements and / or welded.

According to a possible embodiment, the first side walls are 9 ' . 9 " , 9 '"and the second side walls 10 ' . 10 " , 10 '"plate-shaped, so that they can be stored and transported in an overlapping state.

According to one embodiment, the first side walls 9 ' . 9 " , 9 '"and the second side walls 10 ' . 10 " In other words, in the kit according to the invention, the side walls can be applied independently from one side or from another side of the connecting elements, thus further simplifying the manufacturing process as well as the transportation and assembly.

Preferably, the connecting elements 9 ' . 9 " , 9 '"of any size are shaped such that they are stackable respectively, which reduces the storage and transport volume and thus the associated costs.

According to one embodiment, the kit of the invention may comprise reinforcing ribs (not shown in the drawings) which are attached to the frame to stiffen it when it is mounted.

To the described embodiments of the kit according to the invention, one of ordinary skill in the art, to meet any particular needs, may make various additions, modifications, or substitutions of components with other functional equivalents without departing from the scope of the appended claims.
