Description

Technical Field

[0001] The utility model relates to the structure of a mobile power supply vehicle, specifically a three-in-one transformer cabin used for the power supply vehicle. Background Art

[0002] In recent years, many important facilities have increasingly higher requirements for power supply reliability. Once the power supply system suddenly fails and the power supply is interrupted, it will cause significant losses. Therefore, emergency power supply vehicles with power supply guarantee functions are becoming more and more widely used.

[0003] Existing emergency power supply vehicles consist of a generator compartment and a transformer compartment. The transformer compartment and the equipment installed within it are primarily used to rectify the electricity obtained from the grid. This rectified energy is then used to charge mobile energy storage devices. These existing transformer compartments are relatively simple in function, providing only one of the following: low-voltage grid connection, medium-voltage grid connection, and complete power transformation and distribution. Therefore, improvements are necessary. Utility Model Content

The power conversion device 42 includes a low-voltage grid-connected device 421, a medium-voltage grid-connected device 422, a ring network cabinet and a mobile box transformer device arranged in parallel with each other.

[0020] During actual operation, the power conversion device 42 is mainly used to rectify the electric energy obtained from the grid side, and the rectified electric energy is used to charge the mobile energy storage device; when the mobile power supply vehicle moves to the power load that requires emergency power replenishment, the electric energy output by the mobile energy storage device is inverted to provide emergency power replenishment for the power load on the grid side; after the low-voltage grid-connected equipment 421, the medium-voltage grid-connected equipment 422, the ring network cabinet and the mobile box transformer equipment are integrated on the power conversion device 42 at the same time, this application integrates low-voltage grid-connected function, medium-voltage grid-connected function, power distribution protection function and complete power transformation and distribution function, etc., making this application more powerful and more convenient to use.

[0021] The low-voltage grid-connected equipment 421 includes a low-voltage primary grid-connected equipment and / or a low-voltage secondary grid-connected equipment, and the medium-voltage grid-connected equipment 422 includes a medium-voltage primary grid-connected equipment and / or a medium-voltage secondary grid-connected equipment. In this way, the present application can simultaneously realize the low-voltage primary grid-connected function, the low-voltage secondary grid-connected function, the medium-voltage primary grid-connected function, and the medium-voltage secondary grid-connected function, thus making the present application more convenient to use.

In addition to the transformer cabin 4, the vehicle's body 1 also includes a soundproofing cabin 2 and a generator cabin 3. These three cabins are arranged sequentially from the front to the rear of the vehicle. The soundproofing cabin 2 and the equipment installed therein primarily provide sound insulation and waterproofing, while the generator cabin 3 and the equipment installed therein primarily provide power generation.

[0027] Preferably, a third silencer assembly 5 can be installed between the generator compartment 3 and the transformer compartment 4 to reduce noise within the transformer compartment 4. When the power supply vehicle is a high-power vehicle, the third silencer assembly 5 includes two spaced roller shutters 36. A transformer mounted on the floor of the vehicle body 1 is located between the two roller shutters 36 to allow the power conversion device 42 to output a better voltage. When the power supply vehicle is a low-power vehicle, the third silencer assembly 5 is a soundproofing wall 52 composed of multiple soundproofing panels 51. The soundproofing wall 52 is located between the generator compartment 3 and the transformer compartment 4. The soundproofing panels 51 have an inverted V-shaped cross-section along the vertical direction to effectively reduce noise from the transformer compartment 4.
