In the current rail vehicle field, the cable of the pantograph, which is usually mounted on the roof of the vehicle, needs to be taken from the two-position end to the one-position end across the distance of one vehicle. Such a routing method results in an excessively long routing path, difficulty in routing, heavy weight of the cable, and high cost. Moreover, the high-voltage cable passes through the lower part of the pantograph due to the wiring mode, and carbon powder falling off during the operation of the pantograph is easy to damage the cable. In view of this, a redesign of the wiring layout of the high voltage cable on the roof of the rail vehicle is required.

Furthermore, the particular features, structures, materials, or characteristics described may be combined in any suitable manner in any one or more embodiments or examples. Furthermore, various embodiments or examples and features of different embodiments or examples described in this specification can be combined and combined by one skilled in the art without contradiction.
Referring now to fig. 1, an embodiment of the present invention will be described. It should be understood that the following description is only exemplary embodiments of the present invention and does not constitute any particular limitation of the present invention.
It should be noted that the one-position end described herein refers to an end portion of the rail vehicle body on a side close to the rail vehicle head; and the two-position end refers to the end part of the rail vehicle body close to the tail side of the rail vehicle.
As shown in fig. 1, according to a first aspect of an embodiment of the present invention, a rail vehicle roof structure 100 is provided. The rail vehicle roof structure 100 generally includes a pantograph 102, a vacuum interrupter 104, a transient inductor 106, and a voltage transformer 108.
Specifically, the pantograph 102 is mounted on the roof of the rail vehicle, the vacuum circuit breaker 104 is mounted on the roof of the rail vehicle and connected to the pantograph 102, the transient inductor 106 is mounted on the roof of the rail vehicle and connected to the vacuum circuit breaker 104, and the voltage transformer 108 is mounted on the roof of the rail vehicle and connected to the transient inductor 106.
Furthermore, the transient inductance 106 may be located between the voltage transformer 108 and the two-position end 110 of the rail vehicle in the longitudinal direction of the rail vehicle. Furthermore, the transient inductor 106 is connected to a high voltage cable 112, and the high voltage cable 112 is directly taken off the line from the two-position terminal 110.
For a common roof construction of a rail vehicle, a vacuum circuit breaker is generally connected to a voltage transformer. And then the voltage transformer divides the line and is connected with the transient inductor. The high-voltage cable is connected with the transient inductor. When the voltage transformer is separated, the transient inductance is connected, the lightning arrester can be connected, and the lightning arrester is close to the two-position end of the railway vehicle, so that the two-position end does not have enough space for the high-voltage cable to be disconnected. This results in that the high voltage cable connected to the transient inductance can only be run down from the two-terminal to the one-terminal across the distance of one vehicle.
In contrast to the conventional structure in which the vacuum circuit breaker is connected to the voltage transformer, in the rail vehicle roof structure 100 according to the embodiment of the present invention, the vacuum circuit breaker 104 is adjusted to be connected to the transient inductor 106 according to the embodiment of the present invention. In addition, the transient inductor 106 is located between the voltage transformer 108 and the two-position end 110 of the rail vehicle along the longitudinal direction of the rail vehicle, such that the voltage transformer 108 is located outside the area between the transient inductor 106 and the two-position end 110, thereby providing space for the down-line of the high-voltage cable 112. In this way, the high voltage cable 112 can be directly connected to the transient inductor 106 and can be taken off-line directly from the two-position terminal 110 without having to go off-line from the two-position terminal 110 to the one-position terminal across the distance of one vehicle. Therefore, the effects of shortening the wiring path, reducing the weight of the cable and reducing the wiring cost are achieved.
In addition, it is noted herein that in the embodiments described above and below, the adjustment and change of the position of each component still follows the wiring principle and the condition of the insulation gap of each component (i.e., the insulation gap between adjacent live devices is at least 330mm), so that these adjustments do not affect the normal use and operation of each component.
As further shown in fig. 1, the railway vehicle roof structure 100 further comprises a first lightning arrester 114. Specifically, the first lightning arrester 114 is mounted on the roof of the rail vehicle, and the first lightning arrester 114 is connected to the transient inductor 106 and the voltage transformer 108. Further, in the longitudinal direction of the rail vehicle, a first surge arrester 114 is located between the transient inductance 106 and the voltage transformer 108.
Specifically, according to the above-described embodiment, in the conventional railway vehicle roof structure, since the voltage transformer is branched and connected to the lightning arrester in addition to the transient inductance, and the lightning arrester is located near the two-position end of the railway vehicle, there is insufficient down line space at the two-position end.
In the structure provided by the embodiment of the present invention, on the basis of interchanging the positions of the transient inductor 106 and the voltage transformer 108 and adjusting the vacuum circuit breaker 104 to be connected to the transient inductor 106, the present embodiment also adjusts the branching of the existing voltage transformer to be branched by the transient inductor 106, that is, one branching of the transient inductor 106 is branched to be connected to the voltage transformer 108, and the other branching is connected to the high voltage cable 112. Further, in the prior art, the lightning arrester (i.e. the first lightning arrester 114) occupying the two-terminal offline space is adjusted to be connected between the transient inductor 106 and the voltage transformer 108, so that the two-terminal offline space can be sufficiently reserved, and the first lightning arrester 114 can be far away from the two-terminal 110 as far as possible without affecting the functions of the first lightning arrester 114.
Thus, the embodiment of the invention optimizes the arrangement of the roof apparatus. By rearranging the positions of the first lightning arrester 114, the voltage transformer 108 and the transient inductance 106, under the condition of ensuring the wiring principle and the insulation clearance of each component, the voltage transformer 108 and the transient inductance 106 are interchanged, the original branch of the voltage transformer 108 is changed into the branch of the transient inductance 106, the first lightning arrester 114 close to the two-position end 110 is moved to the position between the voltage transformer 108 and the transient inductance 106, and thus the direct offline from the two-position end 110 through the transient inductance 106 can be realized.
With continued reference to fig. 1, in an embodiment of the present invention, the rail vehicle roof structure 100 further includes a first insulator 116. Specifically, the first insulator 116 is connected between the transient inductor 106 and the high voltage cable 112, so that the transient inductor 106 and the high voltage cable 112 can share the first insulator 116.
In the above-described embodiment, the transient inductor 106 and the high-voltage cable 112 share the first insulator 116, so that the supporting insulator of the high-voltage cable 112 can be eliminated. Therefore, under the condition that the high-voltage cable 112 is directly off-line from the two-position end 110 and the installation space and the insulation gap of each device are met, the number of used insulation terminals is not increased, the device arrangement is optimized, and the cable routing path is simplified.
With continued reference to fig. 1, in an embodiment of the present invention, the rail vehicle roof structure 100 further includes a high voltage isolator 118. In particular, the high voltage isolator 118 may be mounted on the roof of a rail vehicle.
Specifically, in order to match the layout of the electrical equipment in the vehicle and optimize the layout of the roof, in an embodiment of the present invention, the high voltage isolation switch 118 may be disposed between the vacuum circuit breaker 104 and the two-position end 110 of the rail vehicle along the longitudinal direction of the rail vehicle. Further, in the embodiment of the present invention, the pantograph 102, the vacuum interrupter 104 and the high voltage disconnector 118 may be sequentially arranged from the one-position end to the two-position end 110 of the rail vehicle along the longitudinal direction of the rail vehicle. Further, in an embodiment of the present invention, the voltage transformer 108, the first surge arrester 114, the transient inductance 106, the first insulator 116 and the high voltage cable 112 can be disposed on the same side of the roof portion of the rail vehicle with respect to the longitudinal centerline of the rail vehicle.
As shown in fig. 1, in the embodiment of the present invention, since the transient inductor 106 needs to be connected with the vacuum circuit breaker 104, the high voltage disconnector 118, the first insulator 116 and the first arrester 114, a transition plate may be disposed on the top of the transient inductor 106. Specifically, the transition plate may further be provided with terminals respectively connected to the vacuum circuit breaker 104, the high voltage disconnector 118, the first insulator 116 and the first arrester 114, so as to realize connection between the transient inductor 106 and the above components.
With continued reference to fig. 1, in an embodiment of the present invention, the rail vehicle roof structure 100 may further include a second insulator 120, a current transformer 122, and a third insulator 124.
Specifically, the second insulator 120, the current transformer 122, and the third insulator 124 may be sequentially connected between the pantograph 102 and the vacuum circuit breaker 104. Further, the second insulator 120, the current transformer 122, and the third insulator 124 can be sequentially arranged from the one-end to the two-end 110 of the rail vehicle in the longitudinal direction of the rail vehicle.
In addition, in the embodiment of the present invention, the railway vehicle roof structure 100 may further include a second lightning arrester 126 and a second voltage transformer 128. Specifically, a second lightning conductor 126 may be connected to the pantograph 102, and a second voltage transformer 128 may be connected to the second lightning conductor 126.
According to the embodiments, the track vehicle roof structure 100 provided by the embodiment of the invention can simplify the routing path without crossing the vehicle. And can reduce cable weight, be favorable to the vehicle to subtract heavy consumption reduction. Furthermore, cable length can be saved, thereby reducing costs.
Furthermore, according to an embodiment of the second aspect of the invention, a rail vehicle body is also provided. The roof of the rail vehicle body is configured as the rail vehicle roof structure 100 described in any of the above. Further, according to an embodiment of the third aspect of the present invention, there is also provided a rail vehicle. The rail vehicle comprises a rail vehicle body as described above.
