Embodiment 2

[0057]The difference between this embodiment 2 and embodiment 1 is that: the top surface of the isolation section 33 of the same group is recessed inward to form a second groove, the second cover plate extends outward to form a second protrusion, and the second protrusion is adapted to be embedded in the first In two grooves. The second groove can extend along the front-to-rear direction of the isolation section 33 of the same group, and the corresponding second protrusion can extend along the front-to-rear direction of the second cover plate, thereby insulating and isolating the left contact piece 81 and the right contact piece 82, and avoiding creeping. electricity phenomenon occurs. The shape of the second protrusion and the second groove is not limited, as long as a plurality of folded surfaces are formed on the contact surface between the same group of isolation segments 33 and the second cover plate.

[0058] The top surface of the adjacent group of isolation sections 3...

Abstract

The invention provides a static-contact set for a switch machine and an automatic shutter and relates to the technical field of machine electricity. The technical problem is solved that in the prior art, since left and right contact sheets between isolated adjacent electric connectors such as static-contact sets are damp, the creepage phenomenon is generated, and electrical conduction is caused. The static-contact set comprises a bottom shell and a cover plate, and multiple isolated electric connectors are installed in the bottom shell; the cover plate covers the bottom shell, insulation sealing is conducted on the contact face between the cover plate and the bottom shell, and the cover plate is used for making the isolated adjacent electric connectors mutually insulated. The static-contact set is used for the switch machine, the cover plate covers the bottom shell, insulation sealing is conducted on the contact face between the cover plate and the bottom shell, and the situation is avoided that since the isolated adjacent electric connectors are damp, the creepage phenomenon of an electric conduction layer is caused. Accordingly, the isolated adjacent electric connectors such as left and right contact sheets are mutually insulated.

Description

technical field [0001] The invention relates to the field of electromechanical technology, in particular to a static contact group and an automatic switch for a switch machine. Background technique [0002] The switch machine refers to the important railway signal infrastructure equipment used to reliably switch the position of the switch, change the direction of the switch, lock the point rail of the switch, and reflect the position of the switch. According to the action energy and transmission mode, the switch machines can be divided into electric switch machines, electro-hydraulic switch machines and electro-pneumatic switch machines. Among them, the electric switch machine is usually driven by a 380-volt three-phase motor to complete the switching work of the switch. The conversion of the switch is controlled by inserting and pulling out the static contact group of the moving contact group of the automatic switch in the switch machine. Specifically, the automatic switc...
