Description

High-temperature-resistant and dustproof box structure for subway one-way conduction device

Technical Field

The utility model relates to a stray current corrodes protection field, concretely relates to an anti high temperature and dirt-proof box structure for subway one-way conduction device.

Background

With the development of science and technology and urbanization, rail transit (subway and light rail) with large traffic volume plays an increasingly important role in cities, and becomes an indispensable part in the life of urban people.

Because the ballast track beds are adopted in the parking lot and the vehicle section, the leakage resistance of the steel rail to the ground is lower than that of the integral track bed on the positive line, and if the track adopts the form of direct full-line communication, the leakage of a large stray current can be caused even if no locomotive runs in the weak insulation area. Therefore, in order to ensure that the positive current does not leak into the ground through the steel rail in the field section, an insulating joint and a common subway one-way conduction device are usually arranged on the steel rail at the boundary point of the ballast track bed and the whole track bed in the entrance section (field). However, although the way of insulation joint plus one-way conduction can relieve the stray current leakage of the section, due to the reverse cut-off function of the subway one-way conduction device, the traction backflow can only flow back to the traction substation from one side of the rail, and the one-way backflow way can cause sudden changes in the voltage and current at the contact position of the train and the steel rail at the moment when the subway passes through the insulation joint, thereby generating high-strength electric arcs and causing the rail potential to rise, and particularly when a locomotive passes through the insulation joint in a regenerative braking way, the arcing phenomenon is more serious due to the change of the current direction. The burning of the insulation joint can have serious consequences, and firstly, the insulation joint is difficult to replace after being burnt, the maintenance time is long, and the normal operation of the train is influenced. And secondly, when the insulation joint is subjected to arc discharge and burnt, the steel rail can be burnt, so that the unevenness of the steel rail is caused, and the driving safety is influenced when the train runs at high speed. The rising of the track potential can not only endanger the safety of passengers, but also increase the leakage of stray current and generate electrochemical corrosion on the peripheral metal structure, thereby causing economic loss and potential safety hazard.

In order to suppress arcing and a rise in track potential when a train enters (exits) the insulation section, the voltage difference between the rails at the two ends of the insulation section should be eliminated so as to be lower than the arcing voltage. The subway one-way conduction device can inhibit the phenomena of electric arc ignition and track potential rise when a train enters (exits) an insulation section. However, a high-power subway one-way conduction device usually needs to work for a long time, which can cause electronic components inside the subway one-way conduction device to generate a large amount of heat energy, and further cause the internal temperature to rise. Excessive temperatures can affect the stability of the device. In addition, along with the increase of subway one-way conduction device live time, the dust has the thermovent to enter into the electrical cabinet structure, deposits in electronic components's surface, because moisture is great in the dust under the humid environment, consequently can make electronic components take place to corrode under the long-term effect, and then shortens electrical components's life. The existing subway one-way conduction device is complex in structure, and in case of failure, the maintenance difficulty is high, and great economic loss can be caused.
