Embodiment Construction

[0028] Figure 1 to Figure 3 An electrical switching device 1 for high or medium voltage according to the invention is shown in . The electrical switching device 1 comprises a housing 2 made of an electrically conductive material, typically made of a metallic material (metal or alloy). In use, the conductive housing 2 is grounded so that there is no electric field on its outer surface. The conductive housing 2 has the general shape of a cuboid and has a top wall 2a , a bottom wall 2b and side walls 2c , 2d , 2e , 2f which together define a sealed inner space 3 . In said sealed inner space 3 is installed an electrical insulation structure 4 comprising a main pipe 4a and an auxiliary pipe 4b. The main pipe 4a and the auxiliary pipe 4b are rigid. The main pipe 4a extends from the side wall 2c to the opposite side wall 2d in the longitudinal direction of the conductive housing 2 . Each auxiliary pipe 4b extends perpendicularly to the longitudinal direction of the conductive ho...

Abstract

An electrical switching device (1) according to the invention comprises: a conductive enclosure (2); a first insulating tube (4a) located inside the conductive enclosure (2); a switch (8) located inside the first insulating tube (4a); second insulating tubes (4b) located inside the conductive enclosure (2), each second insulating tube (4b) extending in a direction that is different from the direction of the first insulating tube (4a), the inside of each second insulating tube (4b) communicating at one of its two ends with the inside of the first insulating tube (4a), the first insulating tube(4a) and the second insulating tubes (4b) extending along a same plane; and electrical components (15-18), such as electrical conductors (15, 16), an earthing switch (17), a surge arrester and a sensor (18), located inside the second insulating tubes (4b) and electrically connected to the switch (8).

Description

technical field [0001] The present invention relates to an electrical switchgear, in particular a switchgear, suitable for railway applications and generally more suitable for high or medium voltage circuits. Background technique [0002] A switchgear is an electrical device that includes switching and protective components such as circuit breakers, disconnectors, earthing switches, surge arresters, fuses and various related equipment (voltage sensors, current sensors, etc.). For example, switching mechanisms are disclosed in EP 2048682 and EP 1245066 . [0003] Typically, a switchgear includes at least a circuit breaker, a disconnector, and an earthing switch. Its function is to convert, control and protect the circuit in which it is placed. [0004] In the railway sector, switchgear is common in railway substations and on the roofs of train cars. Switchgear mounted on train roofs are exposed to harsh working and environmental conditions, which can affect their operation...
