Description

Technical Field

[0001] The utility model relates to the technical field of traction systems, in particular to an SPS power converter for a traction system, which simplifies existing work processes and improves work efficiency. Background Art

[0002] After the traction system is replaced by domestic power, the electrical debugging part of the existing vehicle static debugging cannot use the workshop power supply due to the incompatibility of the workshop power supply. In order not to affect the vehicle debugging cycle and ensure the vehicle delivery time, it is necessary to first charge the battery off the vehicle to ensure that the pantograph debugging work can be completed under battery power. However, even if the battery is charged using a battery charger and discharger, it still faces the risk of battery depletion during pantograph debugging. Once the battery is depleted, it needs to be removed from the vehicle, charged using a battery charger, and then reinstalled, and this process is repeated until the pantograph debugging is completed. This results in an extension of the vehicle debugging cycle and a delay in vehicle delivery. Therefore, the current debugging process brings uncertainty to the vehicle debugging cycle and vehicle delivery time, and the process is complex and inefficient. Summary of the Invention

[0003] The purpose of the present invention is to overcome the defect of the debugging process in the above-mentioned prior art that brings uncertainty to the vehicle debugging cycle and vehicle delivery time, and to provide a traction system SPS power converter, thereby simplifying the existing workflow and improving work efficiency.

[0004] To achieve the above-mentioned purpose, the utility model adopts the following technical solutions: a traction system SPS power converter, the plug end of the converter is connected to the socket box through a bellows, and is connected to the socket end through the socket box, X1 is the workshop power socket, X2 is the workshop power plug, X1:1 is connected to the workshop power 110VDC+ output, X1:2 provides +110V to the peripheral contactor, X1:3 is the negative line of the peripheral contactor, X1:A is the workshop power input, X2:A is the workshop power output, X2:1 is connected to the workshop power contactor coil, X2:2 is short-circuited with X2:4 on the plug with a short-circuit wire, and the vehicle is prohibited from moving when the peripheral is charging, X2:3 is the negative line of the peripheral contactor, X2:4 is short-circuited with X2:2 on the plug with a short-circuit wire, and the vehicle is prohibited from moving when the peripheral is charging, and X2:5 provides +110V to the peripheral contactor.

[0005] Preferably, the left side of the socket box is a socket installation panel for the workshop power supply, the front side is a wire outlet, the wire outlet is connected to the bellows connector, and the right side is a detachable inspection panel.

[0006] Preferably, the overall length of the converter is 20M.

[0007] Preferably, the overall size of the socket box is 200mm*200mm*200mm, and the material is stainless steel.

[0008] Preferably, the inspection panel, the socket installation panel and the wire outlet all use silicone rubber sealing rings.

[0009] Compared with existing technologies, this utility model has the following beneficial effects: It provides a power adapter for the localized replacement workshop of the traction system. This allows the localized replacement traction system vehicle to utilize the original subway vehicle workshop power supply to complete the high-voltage power supply to the vehicle without raising the pantograph, and perform the live portion of the vehicle static commissioning. Using the technical solution of this application, the live portion of the vehicle static commissioning is reduced from five days to two days, a significant improvement.

Obviously, the described embodiments are only some embodiments of the present invention, not all embodiments. Generally, the components of the embodiments of the present invention described and shown in the drawings herein can be arranged and designed in various different configurations.

[0015] like Figure 1 and Figure 2Figure 1 shows a traction system SPS power converter. Basic requirements for the converter: The converter is 20 meters long. The outgoing wires from the converter's plug end are connected to the socket box via a corrugated conduit, and then to the socket end via the socket box. In the figure, X1 represents the workshop power socket; X2 represents the workshop power plug; the inner dashed box represents the socket box, and the outer dashed box represents the converter itself. (X1:1 connects to the 110VDC + output of the workshop power supply. X1:2 provides +110V to the peripheral contactor. X1:3 is the negative line of the peripheral contactor. X1:A is the workshop power input. X2:A is the workshop power output. X2:1 connects to the workshop power contactor coil. X2:2 is short-circuited with X2:4 on the plug with a short-circuit wire. The train is prohibited from moving during peripheral charging. X2:3 is the negative line of the peripheral contactor. X2:4 is short-circuited with X2:2 on the plug with a short-circuit wire.
