[0005] The technical solution for realizing this utility model is as follows:

[0006] The locomotive-specific single-phase inverter power supply includes a housing consisting of a base plate, a top cover, and four side plates. A main control board mounting bracket within the housing divides the interior into upper and lower cavities. One end of the lower cavity integrates a toroidal transformer and an inductor assembly, while the other end houses a capacitor assembly and a filter. An air switch and a lamp panel assembly are mounted on the upper cavity above the capacitor assembly. The lamp panel assembly includes an inverted U-shaped bracket and several LED lamp holders mounted on the top surface of the bracket.

[0007] The capacitor assembly includes two sets of heat sinks arranged in parallel on the base plate. Each set of heat sinks includes two heat sinks. One set of heat sinks is equipped with an absorption capacitor, which is connected to the capacitor above it through a copper strip. The two heat sinks in the other set are connected by a copper strip, and the copper strip is equipped with a non-inductive capacitor.

[0008] Mounting feet are provided on the front and rear sides of the base plate; the mounting feet are L-shaped and each end is provided with a sealing plate with through holes.

[0009] The top cover has mounting holes at positions corresponding to the LED lamp holders for the LED lamp holders to pass through and install; the bottom surface of the bracket has LED lamp holder nuts.

[0010] The top cover of the LED lamp holder is provided with an open cover.

[0011] Two cooling fans are arranged opposite each other on the side plate of the housing near the capacitor assembly. The cooling fans are connected to the outside through a through hole. A hollowed-out wind baffle is installed on the through hole, and two V-shaped brackets are arranged opposite each other on the wind baffle.

[0012] By adopting the above technical solution, the internal cavity of the housing is divided into two parts, making the structure more compact; the toroidal transformer, inductor, filter, capacitor and other components are placed in the lower cavity and combined with the heat dissipation structure to facilitate heat dissipation; the circuit breaker and lamp panel assembly are placed in the upper cavity, with the lamp panel assembly closely attached to the top cover and extending out of the top cover for easy observation by the operator.

[0020] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of this utility model. All other embodiments obtained by those skilled in the art based on the described embodiments of this utility model without creative effort are within the scope of protection of this utility model.

[0021] See Figure 1The diagram illustrates the structure of this application. A locomotive-specific single-phase inverter power supply includes a housing formed by a base plate 1, a top cover 2, and four side plates 3. A main control board mounting bracket 4 divides the housing's interior into upper and lower cavities. One end of the lower cavity integrates a toroidal transformer 5 and an inductor assembly 6, while the other end houses a capacitor assembly 7 and a filter 8. An air switch 10 and a lamp panel assembly 11 are mounted on the upper cavity above the capacitor assembly. The lamp panel assembly includes an inverted U-shaped bracket 11.1 and several LED lamp holders mounted on the top surface of the bracket. By dividing the housing's interior into two parts, the structure is more compact. Placing the toroidal transformer, inductor, filter, and capacitor 16 in the lower cavity, along with a heat dissipation structure, facilitates heat dissipation. The air switch 10 and lamp panel assembly are placed in the upper cavity, with the lamp panel assembly closely attached to the top cover and extending beyond it for easy observation by the operator.

[0022] The capacitor assembly includes two sets of heat sinks arranged in parallel on the base plate. Each set of heat sinks includes two heat sinks 12. One set of heat sinks is equipped with an absorption capacitor 13, which is connected to the capacitor above it via a copper strip. The two heat sinks in the other set are connected by a copper strip, and a non-inductive capacitor 15 is mounted on the copper strip. The capacitor assembly has a compact structure and is easy to install due to the combination of the heat sinks and the copper strip.

[0023] Mounting feet 17 are provided on the front and rear sides of the base plate; the mounting feet are L-shaped and each end is provided with a sealing plate 18 with through holes. The mounting feet fix the entire housing, and the sealing plates are provided to assist in the installation of the inverter.

[0024] The top cover has mounting holes at positions corresponding to the LED lamp holders for the LED lamp holders 11.2 to pass through and be installed; the bottom surface of the bracket has LED lamp holder nuts. The LED lamps are exposed for easy observation and operation. The nuts are installed in reverse, which does not affect the overall aesthetics and facilitates subsequent disassembly and assembly.

[0025] The top cover of the LED lamp holder is equipped with an open cover 9. This provides dust and ash protection.

[0026] Two cooling fans 11.3 are positioned opposite each other on the side panel of the housing near the capacitor assembly. These fans are connected to the outside environment through through holes. A perforated baffle plate 11.4 is installed on the through holes, and two V-shaped brackets are positioned opposite each other on the baffle plate. The heat sink and cooling fans work together to reduce the heat at the capacitor assembly, and the V-shaped brackets assist in the installation of the baffle plate.
