Abstract
A power supply three rail protecting device is characterized by mainly being composed of an insulating upper cover plate, an insulating side cover plate and a support, wherein the support is arranged on sleepers, the insulating upper cover plate and the insulating side cover plate are arranged on the support, and an insulator is arranged on the support. The protecting device is arranged on rail sleepers and arranged on the outer side of travelling rails, is safe in insulation, simple in structure, convenient to install and maintain, solid, endurable and low in cost, is a convenient and practical high-voltage power supply protecting device, greatly avoids potential safety hazards of traditional city railway vehicle debugging, prevents rainwater from corroding power supply three rails, and reduces the maintenance workload of the power supply three rails.
Description
Technical field
The utility model relates to a kind of subway car three rail fender guards of powering.
Background technology
In the past, subway car three rails of powering are naked form, while carrying out the debugging of subway vehicle, power three rails with DC high-voltage, not only bring personal safety hidden danger to commissioning staff, simultaneously also because of power three gauges from car body close to, if there are the conductive bodies such as plain conductor, by car body or its equipment and power supply, three rails are short connects together, and will cause vehicle or its equipment damage; In addition, there is corrosion hidden danger in rainwater sky in power supply three rails, will normally be subject to electricity and maintaining to bring certain influence to vehicle, exists and be subject to electric bad problem, and existing other foreign material to fall on power supply three rails will normally be subject to electricity to bring corresponding potential safety hazard to vehicle simultaneously.
Utility model content
Technical problem to be solved in the utility model is to overcome the power supply safety hidden danger that existing power supply three rails exist and the problem such as bad of powering, thereby provides a kind of safe, reliable, simple in structure and can reduce the fender guard of the three rail line service amounts of power supply.
For solving the problems of the technologies described above; the utility model provides a kind of power supply three rail fender guards, it is characterized in that: be mainly made up of insulation upper cover plate, insulation sides cover plate and support, support is arranged on sleeper; insulation upper cover plate and insulation sides cover plate are rack-mount, and insulator is installed on support.
The utility model fender guard is arranged on track sleeper; and in the outside of rail; insulation safety, simple in structure, installation and easy to maintenance, durable, with low cost; it is a kind of convenient and practical high voltage supply fender guard; greatly avoid the potential safety hazard of subway vehicle debugging in the past; this fender guard avoids rain erosion to arrive power supply three rails simultaneously, has also reduced power supply three rail maintenance workloads.
Brief description of the drawings
Fig. 1 is structural representation of the present utility model.
Detailed description of the invention
With reference to Fig. 1; the utility model is arranged on power supply three rail 3 sides and top and parallel with power supply three rails; and in the outside of rail 2; it is made up of the upper cover plate 9 that insulate, insulation sides cover plate 8, support 6; support is arranged on sleeper 1 by two bracket fixing bolts 5; insulation sides cover plate is rack-mount by insulation sides cover plate bolt of rear end plate 7; insulation upper cover plate is also rack-mount by insulation upper cover plate bolt of rear end plate 10; insulator 4 is installed on support; three rail three faces that make to power are protected, vehicle Supply Security while improving the debugging of subway car.
