In this state, the electric power required for the electric vehicle to pass through the platform in the station is provided with the safety protection device for the special high voltage tram line transmission line in the subway platform and the subway platform, which is normally supplied from the electric power collector for safe operation. There is a purpose.

With respect to the configuration and operation of the present invention will be described in detail the kind of embodiment as follows.

In applying the safety protection device to the extra-high-voltage tramline, the ruled line constructed on the upper part of the tramline by the hanger 7 as shown in the first perspective view of Fig. 1-1 and the exploded perspective view of Fig. 1-2. Injection molding designed to meet the specifications using materials with moderate strength, with excellent electrical insulation and electrostatic shielding effect, and flexible material, but not abrasion, in the extra-high voltage catenary transmission line restrained by (39). In forming an efficient structure of the safety cover 9 injection molded into a mold,

Connection pins (47) connected to the lower side of both sides of the insertion hole (20) formed by opening the lower surface of the safety cover (9) and the insertion groove (23) therein so as to be inserted into the extra-high voltage tram line (3) The insertion hole 45 of the protruding portion 25 is formed in the configuration characterized in that each groove 10 is formed along the both sides of the outside.

When connecting the safety cover (9) manufactured by injection molding as described above, the connecting fixing pin 47 is inserted into the insertion hole 45 of the connecting fixing pin and the connecting bolt insertion hole 15 is punched in the connecting metal piece. (13) is inserted into the grooves 10 formed on both outer sides of the safety cover 9, and the fastening bolt 17 is inserted into the fastening bolt insertion hole 15 of the connecting metal piece 13 to fix the safety cover 9. It is to be connected to the connection to the grounding 19.

In addition, in order to connect the safety cover 9 to the position where the support hanger 7 of the tramline protrudes and the connection intersection point of the tramline transmission line 3 to the left and right, a hanger hole 27 is formed on the upper ends of both ends. It is characterized by inserting the connecting metal piece 13 into the groove 10 formed on both sides of the outer side and fastening it with a fastening bolt 17, thereby providing a safety protection device that exerts an electric insulation and an electrostatic shielding effect on all sections of the station in history. This is about safety protection device of special high voltage tram line transmission line in electric train and subway platform that can prevent electric shock accident and power failure accident in advance.

In detail the operation of the first embodiment of the present invention, Figures 1-3-A is a cross-sectional perspective view of the main faucet state, Figures 1-3-B is a cross-sectional perspective view of the uneven part, faucet state, Figure 1-4 1-5 is a perspective view showing the bottom perspective view, and since 25,000 volts of extra-high voltage alternating current is being transmitted to the extra-high voltage line transmission line 3, it is mounted on the upper portion of the electric vehicle 37. The electric current collector 33 is connected to the extra-high-voltage tramline transmission line 3 and slides to receive power and receive power to the high-voltage incoming line 35 so that electric power is supplied to the electric vehicle 37. will be.

At this time, the electric power collector 33 of the electric vehicle 37 is pushed up by the strong pressure to push up the well so that the contact with the extra-high voltage transmission line (3), the safety cover (9) is pushed upwards, at this time The moving range that is pushed up is protruded on both sides of the lower inner side and stopped at the position where the protruding portion 25 is in contact with the lower side of the extra-high voltage line transmission line 3, so that the power collector 33 is contacted at an appropriate pressure. The electric vehicle 37 can be operated by receiving power power.

In this way, after the electric vehicle 37 safely passes through the platform, the safety cover 9 pushed up to the upper part of the high-voltage tram line 3 is lowered again by the passage of the electric power collector 33 and By performing electrical insulation and electrostatic shielding function between the facility and the ground, it will act to prevent electric shock accidents and sudden power failure accidents.

Referring to the drawings, a second embodiment in which the safety protection device is applied to a high-pressure "T" shaped busbar transmission line 5 is illustrated in the perspective view of Fig. 2-1 and the exploded perspective view of Fig. 2-2. In the case where the transmission line 5 in the form of a "T" busbar is mounted under the high-pressure suspension insulator 30 mounted on the structure installed above the ceiling of the platform in the subway station,

As in the first embodiment, the safety cover 9 having excellent electrical insulation and electrostatic shielding effects can be easily inserted into the transmission line 5 having a "T" shaped busbar. The inner side of the lower surface of the inner surface formed in the form of easy to insert and insert the "T" shaped busbar transmission line 5 in the insertion hole 20 and the insertion groove 23 inside the lower surface by inserting the lower surface The insertion hole 45 of the fixing pin 47 is connected to the protruding portion 25 is formed in the configuration characterized in that each groove 10 is formed along the both sides of the outside.

Therefore, the method and components of connecting the safety cover to each other are the same as in the first embodiment, and the action and effect according to the material and configuration are also the same. Therefore, there may be a change in the simple structure belonging to the basic components of the present invention described above and the effects and effects thereof.

Despite the fact that there are 25,000 volts of alternating current (ACV) in the high-voltage tramline transmission lines and high-voltage "T" busbar-type transmission lines installed by processing in the platform sections of the existing railway and subway stations, Only insulators are installed as a measure for electrical insulation between

As attention is always required for the safe operation of electric vehicles, the present invention provides a special high-voltage catenary transmission line by inserting a safety cover designed in a special structure as a material having good effect of electric insulation and electrostatic shielding. When the electric vehicle passes through the station, the safety cover is pushed up by the strong rising pressure of the power collector, so that the power collector is continuously connected to the power line.
