Abstract
The utility model discloses a DC1500V third rail mechanical subsection structure which has a third rail arranged along with a circuitry. Mechanical subsections are formed corresponding to the spots on the third rail where mechanical subsections need to be located; mechanical subsections is formed in the form of natural disconnection, and at both side of the fracture the third rail realizes electrical continuity the a wire connecting groupware. The wire connecting groupware is composed of an end angle head, a patch board and a contact wire. The end angle head is positioned on the third rail at both sides of the fracture of the mechanical subsection, the patch board is reliably connected with the third rail, and the contact wire is respectively connected with the patch board on the third rail at both sides of the fracture. With the above structure, the utility model enables the DC1500V third rail power supply system to adapt the practical circuitry better and meet the requirement of maintenance. The utility model also has the advantage of simple structure, reliable installation and easy maintenance.
Description
Technical field
The utility model relates to a kind of mechanical segmental structure that is applicable to subway DC1500V three rail electric power systems.
Background technology
In electric power supply system for subway, as the contact system electric power system, often mechanical segmentation need be set on contact system, to adapt to the actual track situation and to satisfy the maintenance needs.And for the DC1500V third rail system, also should mechanical segmentation be set according to actual track situation and maintenance needs, but because of its electric power supply system for subway for China's initiative, there is no mature experience both at home and abroad can use for reference.
Summary of the invention
The purpose of this utility model is at the problems referred to above, and a kind of later-model DC1500V three trailer tool segmental structures are provided, and it is simple in structure, and is easy for installation, and safeguards easily, can be applicable to the metro construction of China better.
For achieving the above object, the technical solution of the utility model is as follows: DC1500V three trailer tool segmental structures, have three rails that install on a road along the line, on three rails to being formed with mechanical segmentation in requisition for the place that mechanical segmentation is set; Described mechanical segmentation forms with open circuited naturally form, and mechanical segmentation fracture both sides three rails are electrically connected by cable connection assembly.The size of machinery segmentation fracture is determined as the case may be.
Above-mentioned cable connection assembly comprises end bends, cable connection panel and electric connection line, end bends is arranged on three rails of mechanical segmentation fracture both sides, cable connection panel reliably contacts with three rails, and electric connection line is connected with cable connection panel on three rails of fracture both sides respectively.According to the needs increase and decrease electrically connecting clamp of current-carrying capacity and the quantity of electric connection line.
For eliminating the electrocorrosion between copper, the aluminium, above-mentioned cable connection panel is the aluminium cable touch block, and reaching electric connection line is the copper electric connection line, and both connect by the copper-aluminium transition connection terminal.
Above-mentioned cable connection panel is provided with 3 connecting bores, the on-site installation of being more convenient for.
The place that above-mentioned needs are provided with mechanical segmentation comprises track switch, closed guard gate, the anti-place of changing sides in door and the station of flooding.
The utility model makes DC1500V three rail electric power systems adapt to actual track situation and satisfied maintenance needs better by the employing said structure, and simple in structure, installs reliably, is convenient to safeguard.
