In addition, those skilled in the art may combine and combine the different embodiments or examples described in this specification and the features of the different embodiments or examples, without contradiction.

[0045] Combine the following Figure 1-Figure 4 The utility model describes the traction high-voltage box. It is understandable that the operation of a rail train requires the support of multiple electrical devices, such as circuit breakers, controllers, inverters, etc. These electrical devices are distributed at the bottom of the train, and each electrical device is connected to each other or to related devices through interfaces and lines. However, the distributed setting makes the structure of the bottom of the train complex, and the equipment is inconvenient to disassemble and assemble, and difficult to maintain.

[0046] In view of the above problems, a traction high-voltage box 100 according to an embodiment of the utility model includes a box body 110, a plurality of partitions 120, an isolating switch control unit, a circuit breaker unit and a pre-charging unit.

[0047] See also Figure 1 and Figure 2 As shown, specifically, the isolating switch control unit, the circuit breaker unit and the pre-charging unit are all arranged in the box body 110, and the isolating switch control unit, the circuit breaker unit and the pre-charging unit can be connected by copper busbars and cables. The partition 120 is arranged in the box body 110 and connected to the box body 110. The multiple partitions 120 divide the box body 110 into a first chamber 101, a second chamber 102, and a third chamber 103. The first chamber 101, the second chamber 102 and the third chamber 103 are connected in sequence. For example, the partition 120 is provided with a through hole, or the partition 120 and the inner bottom wall of the box body 110 are spaced a certain distance to form a connecting groove to connect the first chamber 101, the second chamber 102 or the third chamber 103. As shown Figure 2 As shown, the box body 110 is roughly in the shape of a rectangular parallelepiped, and two partitions 120 are arranged in the box body 110. The two partitions 120 are arranged at intervals in the length direction of the box body 110, so as to divide the internal space of the box body 110 into a first chamber 101, a second chamber 102 and a third chamber 103.

[0048] The isolating switch control unit is arranged in the first chamber 101, the circuit breaker unit is arranged in the second chamber 102, and the circuit breaker unit is connected to the isolating switch control unit; the pre-charging unit is arranged in the third chamber 103, and the pre-charging unit is connected to the circuit breaker unit and the isolating switch control unit. The isolating switch control unit, the circuit breaker unit and the pre-charging unit are connected by copper bars and cables, and the copper bars can be connected to the partition 120. In this way, the isolating switch control unit, the circuit breaker unit and the pre-charging unit are integrated into the box body 110 to form a whole, so that the bottom of the train car is neater and the bottom layout of the train car is simpler. In addition, without the need to set an interface for each unit separately, the number and type of interfaces of the isolating switch control unit, the circuit breaker unit and the pre-charging unit can be reduced, reducing the difficulty of assembly; at the same time, the length of the connecting cable between the isolating switch control unit, the circuit breaker unit and the pre-charging unit is shortened, which is convenient for wiring.

[0049] A main maintenance door 130 is provided on one side of the box body 110. The main maintenance door 130 is used to maintain the circuit breaker unit and the pre-charging unit with a higher fault frequency. The main maintenance door 130 is connected to the second chamber 102 and the third chamber 103. The technician can access the circuit breaker unit and the pre-charging unit through the main maintenance door 130. By providing the main maintenance door 130 to maintain the units with a higher maintenance frequency, the disassembly and assembly process is simplified and the efficiency is improved. It is understandable that the components included in the disconnector control unit, the circuit breaker unit and the pre-charging unit have different fault occurrence rates due to different loads and manufacturing technologies. The maintenance cycle and maintenance frequency of each component can be obtained based on experience.

[0050] According to the traction high-voltage box 100 of the embodiment of the utility model, by integrating the isolating switch control unit, the circuit breaker unit and the pre-charging unit into the box body 110 to form a whole, the bottom of the train compartment is neater, the layout of the bottom of the train compartment is simpler, the number and type of interfaces of the isolating switch control unit, the circuit breaker unit and the pre-charging unit are reduced, and the difficulty of assembly is reduced; at the same time, the length of the connecting cable between the isolating switch control unit, the circuit breaker unit and the pre-charging unit is shortened, which is convenient for wiring. By setting the main maintenance door 130 on the box body 110 to maintain the units with a high frequency of post-failure maintenance, the process of post-maintenance and disassembly is simplified, and efficiency is improved.

[0051] See also Figure 1 and Figure 3As shown, according to some embodiments of the present invention, the main maintenance door 130 includes a door panel 131 and a connecting buckle 132. One end of the connecting buckle 132 is connected to the box body 110. The connecting buckle 132 can be connected to the box body 110 by screws. The other end of the connecting buckle 132 is connected to the door panel 131. The connecting buckle 132 is rotatable. The door panel 131 can be opened or closed by rotating it, which is convenient for operation. Figure 1 As shown, there are two connecting buckles 132, and both connecting buckles 132 are connected to one side edge of the door panel 131. In some embodiments, a handle 135 is provided on the outer side of the door panel 131 to facilitate moving the door panel 131.

[0052] According to some embodiments of the present invention, the connection buckle 132 includes a fixed seat 133 and a rotating plate 134. The fixed seat 133 is connected to the box body 110, and the fixed seat 133 is provided with a buckle groove 136. The rotating plate 134 is connected to the door panel 131, and the rotating plate 134 is provided with a connecting hole. The rotating plate 134 includes a limit bar, and the limit bar constructs a side edge of the connecting hole. The fixed seat 133 is inserted into the connecting hole, and the limit bar is embedded in the buckle groove 136, and the limit bar can rotate relative to the buckle groove 136. Figure 2 and Figure 3 As shown, both ends of the fixed seat 133 are plate-shaped and fixedly connected to the box body 110, the middle part of the fixed seat 133 is a protruding block, and the buckling groove 136 is arranged on the protruding block; one end of the rotating plate 134 is fixedly connected to the door panel 131, and the other end of the rotating plate 134 is provided with a connecting hole, the limit bar is located at the other end of the rotating plate 134, the protruding block is passed through the connecting hole, and the limit bar is embedded in the buckling groove 136. When the door panel 131 is rotated, the limit bar rotates in the buckling groove 136 to keep the fixed seat 133 connected to the rotating plate 134.

[0053] like Figure 5 As shown, in some embodiments, the width of the opening of the buckle groove 136 is slightly greater than the thickness of the limit strip, and the bottom width of the buckle groove 136 is slightly greater than the width of the limit strip. Figure 5 In the position shown in FIG. 1 , the limit bar is vertically embedded in the buckle groove 136, and the limit bar is located at the opening of the buckle groove 136; when the door panel 131 is rotated to the open state, as shown in FIG. Figure 5 When the middle door panel 131 rotates to a horizontal position, the limit bar moves to the bottom of the buckle slot 136, and the fixing seat 133 remains connected to the rotating plate 134. Figure 5 The door panel 131 is lifted up in the direction shown in the figure to disengage the limiting strip from the buckling groove 136, thereby moving the door panel 131 to be removed for easy operation.

[0054] See also Figure 2As shown, according to some embodiments of the present invention, the outer wall of the box body 110 is provided with a storage groove 111, the storage groove 111 is communicated with the first chamber 101, and the connection end of the disconnector control unit is located in the storage groove 111. The relevant equipment of the train is connected to the connection end of the disconnector control unit, and the storage groove 111 can protect the connection between the connection end and the electrical equipment, and the connection end is arranged in the storage groove 111 of the outer wall of the box body 110 for easy assembly and disassembly or assembly during later maintenance.

[0055] It is understandable that during the maintenance process, train carriages need to be lifted and fixed using specific lifting devices, and moving train carriages requires a large space and is relatively cumbersome. Figure 3 As shown, in some embodiments, the box 110 includes a first plate 116, and the storage slot 111 and the main maintenance door 130 are both located on the first plate 116, so that the storage slot 111 and the main maintenance door 130 are integrated on the same side of the box 110, so that technicians do not need to move multiple times during the maintenance process, which improves efficiency and requires less operating space.

[0056] See also Figure 4 As shown, according to some embodiments of the utility model, the box body 110 also includes a second plate body 117, the second plate body 117 is opposite to the first plate body 116, and a second maintenance door 140 and a third maintenance door 141 are provided on the second plate body 117, the second maintenance door 140 is connected to the second chamber 102 and the third chamber 103, so as to facilitate maintenance of the other side of the circuit breaker unit and the pre-charging unit; the third maintenance door 141 is connected to the first chamber 101, so as to facilitate maintenance of the isolating switch control unit. Among them, the use frequency of the second maintenance door 140 and the third maintenance door 141 is lower than the use frequency of the main maintenance door 130, and the second maintenance door 140 and the third maintenance door 141 can be connected to the second plate body 117 by screws. In this way, the connection ends of the main maintenance door 130 with a higher use frequency and the isolating switch control unit are arranged on the same side, and the second maintenance door 140 and the third maintenance door 141 with a lower use frequency are arranged on the other side of the box body 110, so as to facilitate maintenance, save operation space, and reduce maintenance costs.

Among them, the high-voltage cable is received in one of the first row of wire troughs and the second row of wire troughs, and the low-voltage cable is received in the other of the first row of wire troughs and the second row of wire troughs. In this way, the high-voltage cable can be separated from the low-voltage cable, reducing the interference between the high-voltage cable and the low-voltage cable. It can be understood that the above-mentioned high voltage and low voltage are relative concepts. For example, the voltage at the input end of the isolating switch control unit is higher than the voltage at the output end. The cable connected to the input end is a high-voltage cable, and the cable connected to the output end is a low-voltage cable.

[0058] See also Figure 1 As shown, according to some embodiments of the present invention, a convex shell 112 is provided on the outer wall of one end of the box body 110, and a fourth chamber is constructed in the convex shell 112, and the fourth chamber is connected to the third chamber 103.

The convex shell 112 can be welded to the box body 110, or the convex shell 112 can be integrally formed with the box body 110.

[0059] like Figure 2 As shown, in some embodiments, the box 110 is in a cubic shape, and the box 110 may include a crossbeam 114, and there may be multiple crossbeams 114, and the multiple crossbeams 114 are all located at the edges of the box 110. The multiple crossbeams 114 constitute a frame structure, which plays a role in supporting and improving the strength of the box 110. At least one end of the crossbeam 114 is provided with a connecting portion 115, and the connecting portion 115 is used to connect with the chassis of the train compartment. The connecting portion 115 is arranged on the crossbeam 114 to improve the stability of the installation of the traction high-voltage box 100. For example, the connecting portion 115 can be a connecting through hole, and the connecting portion 115 is connected to the chassis by bolts. The box 110 can also include multiple reinforcing beams, which are connected between two crossbeams 114, and the reinforcing beams play a role of auxiliary support.

The traction high-voltage box 100 is the traction high-voltage box 100 as described above, and the traction high-voltage box 100 is arranged on one side of the chassis. The isolating switch control unit, the circuit breaker unit and the pre-charging unit are integrated into the box body 110 by the traction high-voltage box 100, which simplifies the structure of the chassis, reduces the number and types of interfaces, and reduces the difficulty of assembly; at the same time, the length of the connecting cable between the isolating switch control unit, the circuit breaker unit and the pre-charging unit is shortened, which facilitates wiring.
