Abstract

The utility model discloses a sand table model for urban rail traffic traction power distribution and an overhead contact system. The sand table model is characterized by comprising a sand table, a subway system model placed on the sand table and an overhead contact system which is connected with the subway system model via a circuit, wherein the subway system model comprises a subway rail, subway stations and subway vehicles placed on the subway rail; the overhead contact system comprises two main substations mutually connected via the circuit, two traction substations and a step-down substation; the subway station adopts a portal structure whose line is provided with devices and various lines such as a section insulator, an overlap, a center anchor section, a feed line, an electric coupler and a return wire, and the signal signs are complete; the overhead contact system is connected with a power supply and can be connected with 12V voltage, and the overhead contact system provides power for the subway vehicles for operation. The sand table model for the urban rail traffic traction power distribution and overhead line system is basically identical with a real object and can be used for teaching; and the teaching quality, the teaching speed and the learning efficiency of the students are greatly improved.

Description

A kind of sand table model that becomes distribution and contact net for the urban track traffic traction

Technical field

The utility model relates to teaching equipment, is specially a kind of sand table model that becomes distribution and contact net for the urban track traffic traction.

Background technology

Along with the progress of society and the development of science and technology, the construction of urban track traffic more and more is general with using, and the professional and technical personnel of urban track traffic also more and more is that society is required, and this just needs us to turn out the professional and technical personnel of a large amount of track traffics.Yet, can only rely on single books teaching to add on the spot training on operation to the professional and technical personnel's of track traffic training now, and the teaching of books can only rely on simple literal and picture to be introduced, when carrying out the books teaching, because of without in kind as reference, so the quality of instruction of books teaching is limited, teaching speed is extremely slow, and student's understanding is also very difficult.

The utility model content

The utility model is to provide a kind of sand table model for urban track traffic traction change distribution and contact net, to solve the shortcoming and deficiency in the above-mentioned background technology.

The technical matters that the utility model solves realizes by the following technical solutions:

A kind of sand table model that becomes distribution and contact net for the urban track traffic traction, be characterised in that, it is by sand table, be positioned over the subway system model on the sand table, consist of by contact net system three parts that circuit is connected with the subway system model, described subway system model is by underground railway track, the subway station, and the railcar that is positioned on the underground railway track forms, contact net system is by passing through interconnective two main transformer stations of circuit, two traction substations and a stepdown substation consist of, portal structure is adopted in described subway station, its circuit is provided with section insulator, overlap, the central anchor joint, feed line, electric connector, equipment and the various circuits such as return wire, marker is complete, described contact net system is connected with power supply, can lead to 12 volts of voltages, railcar is subjected to the electricity operation from contact net system.

Beneficial effect: the utility model is mainly used in introducing standard and the composition of urban track traffic power supply system of electric traction, traction power supply control and operation, the formation of contact net, represent more intuitively real system, the utility model is simple in structure, employing is imparted knowledge to students with essentially identical simulation system in kind and is drilled with the student, has greatly improved quality of instruction, teaching speed and student's learning efficiency.

Embodiment

Below in conjunction with accompanying drawing embodiment of the present utility model is described in detail as follows:

Referring to shown in Figure 1, a kind of sand table model that becomes distribution and contact net for the urban track traffic traction, be characterised in that, it is by sand table 1, be positioned over the subway system model on the sand table, consist of by contact net system three parts that circuit is connected with the subway system model, described subway system model is by underground railway track 2, subway station 4, and the railcar 3 that is positioned on the underground railway track forms, contact net system is by passing through interconnective two main transformer stations 5 of circuit, two traction substations 6 and a stepdown substation 7 consist of, portal structure is adopted in described subway station, its circuit is provided with section insulator, overlap, the central anchor joint, feed line, electric connector, equipment and the various circuits such as return wire, marker is complete, described contact net system is connected with power supply, can lead to 12 volts of voltages, railcar is subjected to the electricity operation from contact net system.

The utility model is mainly realized the analog functuion of traction power supply, realizes the analog simulation of traction power supply, physically adds the return wire mode by electrification power supply direct-furnish and dwindles with certain proportion, represents real system; Can realize the integrated control functions in main transformer station, traction substation, stepdown substation, be convenient to teacher's teaching and student's study rehearsal, greatly improving the quality of teaching is pace of learning.
