Problems solved by technology

[0004] Now, given the constraints of field installations, the scheme is not entirely satisfactory
In fact, it is often difficult to assemble the rear of the panel at the installation site, mainly because of inaccessibility, so that installers sometimes tend to reduce the use of nuts and bolts
As a result, the performance of the electrical cabinet is no longer guaranteed (especially in the case of internal arcing)

Embodiment Construction

[0046] Throughout the description, it should be noted that the terms "front", "rear", "top", "bottom", "vertical" and "horizontal" are to be understood as considering the position of the electrical cabinet 2 of the switchboard 10 on the floor during installation. The usual positioning on .

[0047] Also, it should be noted that in Figure 1-3 and 5-7A, the axis H represents the horizontal axis and the axis V represents the vertical axis.

[0048] refer to figure 1 , shows a switchboard 10 comprising four electrical cabinets 2 assembled by means of the assembly system 1 according to the invention.

[0049] According to the invention, the assembly system 1 comprises four metal rear fixing plates 3 . Each rear fixing plate 3 is fixed to the rear side 5 a of the rear portion 2 a of each electrical cabinet 2 .

[0050] Furthermore, each rear fixing plate 3 extends vertically along the rear side 5a of the corresponding electrical cabinet's rear portion 2a and has a substantially C...

Abstract

The invention relates to a system (1) for assembling electrical cabinets (2) in a switchboard (10), comprising: a fixing ring (6) extending vertically along the rear side (5a) of each electrical cabinet; one or several Assembly rails (4), each assembly rail comprising a vertically extending insertion opening (7), each assembly rail designed to slide vertically along the group formed by the engagement of the two fixing rings of two adjacent electrical cabinets , the two fixing rings (6) are located in the insertion opening.

Description

technical field [0001] The invention relates to the field of electrical cabinets for switchboards, and in particular to solutions for connecting such electrical cabinets to one another. [0002] The invention relates more particularly to electrical cabinets in the form of modular units with fixed or removable equipment insulated by air or gas inside a metal housing. Such a unit or cabinet can be used, for example, to form a high voltage section of an HV / LV distribution station as well as a high voltage transmission or distribution station. In this application, the term "high voltage" (HV) refers to voltages greater than 1000 volts. Background technique [0003] Traditionally, the assembly of electrical cabinets to each other in a switchboard is generally done by using nuts and bolts. [0004] Now, given the constraints of field installations, this solution is not entirely satisfactory. In fact, it is often difficult to assemble the rear of the panel at the installation si...
