This electrical switching device, able to be integrated into an electrical traction box including a cooling device of the switching device, includes an electrical assembly provided with an electrical switching element. This switching device also includes a base for receiving the electrical assembly, intended to be positioned between the electrical assembly and the cooling device, and pressing elements for pressing the electrical assembly extending between the support element and the base and configured to exert a bearing force on the base, able to keep the base bearing against the cooling device when the switching device is integrated into the traction box.

A cooling aeraulics device is for cooling an element of a rail vehicle. The aeraulics device is designed to be placed on a roof of the rail vehicle and includes a conduit, which extends substantially longitudinally in relation to the rail vehicle. The conduit includes, successively, a front portion equipped with a front opening for the intake of air, a central portion, in which is housed the element to be cooled, and a rear portion, equipped with a rear opening for the discharge of exhaust air. A surface of a transverse cross-section of the conduit evolves, from the front opening to the rear opening, so as to generate an acceleration of the flow of air in the conduit through the Venturi effect.

A device for insulating an electrically conducting plane having a first electric potential relatively to a second electric potential is provided. The device comprises an insulating substrate including two parallel planar surfaces, a first conducting outer layer and an electrostatic field reducer. The electrostatic field reducer reduces the value of the electrostatic field in a point of the peripheral edge, the reducer includes at least one conducting area distinct from the first outer layer, positioned on the first surface of the insulating substrate and/or in the insulating substrate. The reducer reduces the value of the electrostatic field in this point relative to the value of the electrostatic field in this point in the absence of the conducting area. The conducting area has a potential with a value strictly comprised between the values of the first and second potentials.
