Obviously, the described embodiments are part of the embodiments of the present utility model, rather than all of them. Based on the embodiments in the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.

[0029] In addition, the technical features involved in different implementation manners of the present utility model described below can be combined with each other as long as they do not conflict with each other. The embodiments of the present utility model are described in detail below, and the examples of the embodiments are shown in the accompanying drawings, where the same or similar reference numerals indicate the same or similar elements or elements with the same or similar functions throughout.

[0030] The on - vehicle disconnecting switch is a device used to isolate voltage and transmit current at the same time.

[0031] In this embodiment, since the high - voltage disconnecting switch has an input end and an output end, where the input end is connected to the pipe busbar and the output end is connected to the transformer to transmit the alternating current on the pipe busbar to the transformer.

[0032] In order to prevent the transformer from being impacted by over - voltage during operation, thereby causing equipment damage, a disconnecting switch is installed on the rectifier trolley.

[0033] However, since the disconnecting switch and the transformer are mainly connected by a connection plate, during operation, the connection plate is prone to shaking, so that the connection plate may break, and then the voltage isolation stability of the disconnecting switch is poor.

[0034] Please refer to Figure 1 and Figure 2, one specific embodiment of the present utility model provides a vehicle-mounted disconnect switch to solve the problem of poor isolation voltage stability mentioned above.

[0035] A vehicle-mounted disconnect switch is used for a rectifying trolley. The rectifying trolley includes a transformer 4. There is a connecting plate 13 connected between the vehicle-mounted disconnect switch and the transformer 4. The vehicle-mounted disconnect switch includes: an isolation platform 2, and the isolation platform 2 is provided with a support member 11. The support member 11 is connected to the connecting plate 13 to support the connecting plate 13; a switch assembly 1 is arranged on the isolation platform 2.

[0036] In the present utility model, by installing the support member 11 on the isolation platform 2, the support member 11 supports the connecting plate 13 arranged thereon, so that the support member 11 is not affected by the shaking caused by external conditions, improving the mechanical strength of the vehicle-mounted disconnect switch, and further enhancing the stability of power transmission from the vehicle-mounted disconnect switch to the transformer 4.

[0037] Please refer to Figure 2 and Figure 3 , in one specific embodiment, the support member 11 includes a column 112. Since the support member 11 is arranged on the isolation platform 2, the column 112 is fixed above the isolation platform 2. There are three columns 112 arranged in parallel and at intervals;

[0038] As the simplest form of the support member 11, the column 112 has a simple structure and strong versatility.

[0039] In one specific embodiment, the support member includes: a reinforcement part 111 and a column 112. One side of the reinforcement part 111 is closely attached to the column 112, and both the reinforcement part 111 and the column 112 are fixed on the isolation platform 2. There are three columns 112 and three parts of the reinforcement part 111 arranged in parallel and at intervals;

[0040] As one specific manifestation form of the support member 11, the reinforcement part 111 can provide stronger support force for the column 112.

[0041] Among them, the reinforcement part 111 is a triangular support plate, and one side of the triangular support plate is closely attached to the column 112;

[0042] A triangle has good stability. Therefore, using the triangular support plate as the reinforcement part 111 can have a good supporting effect on the support member 11.

[0043] Optionally, the reinforcement part 111 is any component that can perform secondary reinforcement on the column 112, such as a rectangular support plate or a reinforcing rib.

[0044] Please refer to Figure 2 and Figure 3, in one specific embodiment, the isolation platform 2 includes an extension column 21. The extension part 21 extends outward from the isolation platform 2 and is suspended on the isolation platform 2; the support member 11 is installed on the extension part 21.

[0045] It can be understood that: on the extension part 21, the support member 11 can also be a column 112, or a reinforcing part 111 and a column 112 can be provided simultaneously, or in the form of any functional component of the support connecting plate.

[0046] Please refer to Figure 2 , Figure 3 and Figure 4 , the switch assembly 1 further includes a sleeve assembly 12; the sleeve assembly 12 includes a first sleeve assembly 121. The first sleeve assembly 121 is installed at the top of the support member 11 and is fixedly connected to the support member 11.

[0047] The sleeve assembly 12 is connected between the support member 11 and the connecting plate 13.

[0048] Since the connecting plate 13 is mainly used for transmitting current, the sleeve assembly 12 is made of an insulating material to prevent current from being introduced into the support member 11, thereby causing an electric leakage accident.

[0049] Optionally, the sleeve assembly 12 is a cylinder, and a number of rings are connected around the outside of the cylinder.

[0050] Please refer to Figure 2 , Figure 3 and Figure 4 , the switch assembly 1 further includes: a frame 14, a driving member 15, a telescopic rod 16 and a moving contact 17.

[0051] The frame 14 is fixedly installed on the isolation platform 2. The driving member 15 is arranged at the bottom of the frame 14 and is connected to the telescopic rod 16. A pair of telescopic rods 16 are arranged in parallel above the driving member 15. At the same time, the driving member 15 drives the telescopic rod to move up and down, driving the moving contact 17 to move up and down together.

[0052] One end of each of the two output shafts of the driving member 15 is respectively provided with a telescopic rod 16. The upper end of the telescopic rod 16 is connected to the cross beam at the highest horizontal position. A third sleeve assembly 123 is provided on the cross beam. The top of the third sleeve assembly 123 is provided with a connecting plate 13, and the moving contact 17 is fixed above the connecting plate 13.

[0054] The switch assembly 1 further includes: a second sleeve assembly 122, a third sleeve assembly 123 and a flexible copper strip 19;

[0055] The second sleeve assembly 122 and the third sleeve assembly 123 are connected via a portion of the connecting plate 13 and the soft copper strip 19 .

[0056] In a specific embodiment, the frame 14 is formed by splicing two longitudinal beams, three transverse beams and four vertical beams; one of the transverse beams is installed at the bottom of the frame 14, and a driving member 15 is installed on the transverse beam.

[0057] Among them, the cross beams, longitudinal beams and vertical beams of the frame 14 are all composed of three fixed plates;

[0058] Specifically, two fixed plates are arranged side by side with an interval, and the two sides of the third fixed plate are vertically installed between the two fixed plates arranged side by side, forming an "I" shape. Alternatively, three or more fixed plates can be used for splicing, such as using four fixed plates to form a closed space.

[0059] The second sleeve assembly 122 is on another crossbeam, a connecting plate 13 is provided at the top of the second sleeve assembly 122, a soft copper belt 19 is provided between the second sleeve assembly 122 and the third sleeve assembly 123, and both sides of the soft copper belt 19 are connected to the second sleeve assembly 122 and the third sleeve assembly 123 through the connecting plate 13;

[0061] When it is necessary to draw power, the driving member 15 drives the telescopic rod 16 to move upward, and at the same time drives the moving contact 17 to move upward, so that the moving contact contacts the tube bus (lead out below). After drawing power from the tube bus, the current is transmitted to the transformer 4 through the connecting plate 13 and the soft copper strip 19;

[0062] When the power supply is finished, the driving member 15 drives the telescopic rod 16 to move downward, and at the same time drives the moving contact 17 to move downward, so that the moving contact is disconnected from the tube busbar.

[0063] See also Figure 2 , Figure 3 and Figure 4 The switch assembly 1 also includes a pressure plate 18; the pressure plate 18 is installed at the top and bottom of the connecting plate 13, and is used to abut the connecting plate 13, thereby enhancing the connection stability of the connecting plate 13 and avoiding deviation, and at the same time avoiding current breakdown of the connecting plate 13 due to excessive current.

[0064] In this embodiment, the pressing plates 18 are installed only on the connecting plate 13 where the supporting member 11 is located; at least one pair of pressing plates 18 is installed on the connecting plate 13 .

[0065] Please refer to again Figure 1 In some embodiments of the present utility model, a rectifying trolley is further provided.

The switch assembly 1 is used to contact or disconnect from the pipe busbar and is connected to the transformer 4, so that the on-vehicle disconnecting switch 1 takes power from the pipe busbar and outputs it to the transformer 4.

[0066] After the on-vehicle disconnecting switch contacts the pipe busbar to take power, the on-vehicle disconnecting switch takes power from the pipe busbar and conveys the current to the transformer 4 through a connecting plate 13. By providing the on-vehicle disconnecting switch, a support member 11 is provided on the isolation platform 2 of the on-vehicle disconnecting switch, and a connecting plate 13 is provided on the support member 11. Thus, the support member 11 supports the connecting plate 13, the stability of the on-vehicle disconnecting switch transformer 4 is strong, and the power-taking efficiency of the rectifying trolley is high.
