Embodiment Construction

[0024] Such as figure 1 As shown, a medium voltage (MV) distribution substation 1 is installed between an input 2 of the power system and at least one customer feeder 3 supplying different loads. The current interruption and / or earthing function is performed specifically with respect to each mains phase A, B and C at the location of the substation 1 . Other functions can be added, in particular the measurement of different parameters can be added.

[0025] The substation 1 thus comprises several types of units associated with each other. Modular systems are known, in which each functional unit comprises means for performing at least one function and can be associated with another functional unit of the same or a different type in order to form an assembly as best as possible to the user's requirements: cf. SM6 from Schneider Electric.

[0026] The functional unit 4 of the MV substation 1 comprises an enclosure, usually made of metal, containing at least one electrical devic...

Abstract

The connector (250) has a portion including an outer shell (252) made of rigid material around deformable material. An interface arranged between the deformable material and the shell is sealed. Thickness of the deformable material is increased according to a constant slope (alpha) between two ends of the portion while excluding a connection zone (260) that is adjacent to a connection part (212) of another portion. Thickness of an elastomeric material of the latter portion is increased according to a slope, which is four times that of the constant slope.

Description

technical field [0001] The invention relates to a simplified connection between a switching unit and a customer connection interface in a medium voltage distribution station. In particular, the invention relates to an element comprising an end piece as a connection interface, designed to emerge from a medium-voltage substation, and a connection device designed to be fitted on an electrical switching unit of the substation. The connector comprises a portion of deformable material overmolded on the current conductors, which enables an electrical connection to be obtained by contact between flat surfaces inside the substation. At least at the height of the exposed portion, the rigid housing enables a durable connection to be obtained via the cable. Background technique [0002] In electrical installations, especially in medium voltage MV substations (sometimes also called high voltage HVA), i.e. around 1 to 52kV or 75kV, the different switch units for breaking current and / or m...
