Description

Technical Field

[0001] Embodiments of the present disclosure relate to an electrical system for a mobile power generation device and a mobile power generation device. Background Art

[0002] With the development of the power industry, there are more and more equipment driven by electricity and power consumption scenarios. Generally, electricity is provided by fixed power plants and power grids; however, due to various reasons, fixed power plants and power grids cannot meet the power demands of users. For example, when the grid capacity is insufficient or the power generation of a fixed power plant is insufficient due to maintenance, faults, lack of fuel, etc., the power demand may exceed the grid capacity or the power generation of the fixed power plant, resulting in power outages. For another example, when natural disasters such as typhoons and earthquakes damage the power grid or power equipment, power outages and other situations will occur. For another example, in some construction sites and mine shaft scenarios without a power grid, the power demand cannot be met or the cost of laying a power grid is relatively high.

[0003] On the other hand, a mobile power generation device is a power generation device that can be moved or transported. Therefore, the mobile power generation device can be transported to various scenarios with insufficient power or no power, thereby meeting the power demands of users. Summary of the Invention

[0004] Embodiments of the present disclosure provide an electrical system for a mobile power generation device and a mobile power generation device. By setting the first output terminal of the generator switch cabinet at the bottom of the electrical cabin, and the first output terminal can be electrically connected to an external load through a connection conductor via a first hollow portion on a first bottom plate, the first output terminal can be connected to the external load through the connection conductor by utilizing the distance between the electrical cabin on the transportation means and the ground. Moreover, since the first output terminal of the generator switch cabinet is set at the bottom of the electrical cabin, the space occupied by the first output terminal in the electrical cabin can be reduced, and further the space or volume of the electrical cabin can be reduced. Thus, the electrical system can reduce the size of the electrical system and the difficulties of installation, maintenance, and repair of the electrical system by optimizing the layout of the electrical system, so that the mobile power generation device adopting the electrical system can meet various transportation requirements while having a relatively high power generation capacity, and can also improve the utilization efficiency of the mobile power generation device.

[0031] To make the objectives, technical solutions, and advantages of the embodiments of the present disclosure clearer, the technical solutions of the embodiments of the present disclosure will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present disclosure. Obviously, the described embodiments are some, but not all, of the embodiments of the present disclosure.

The terms "first", "second" and similar words used in this disclosure do not denote any order, quantity or importance, but are only used to distinguish different components.

[0033] Currently, mobile power generation devices can be transported to various scenarios with insufficient power or no power, thereby meeting the power needs of users. However, the transportation tools for high-power mobile power generation devices are relatively large in size. Due to the limitations of road natural conditions or the requirements of road regulations, the relatively large-sized transportation tools may not be able to smoothly and quickly transport the mobile power generation devices to the areas where users are located. Thus, the size of the transportation tool has also become one of the main factors restricting the power generation capacity of mobile power generation devices. By making the layout of each component and system in the mobile power generation device more compact, the size of the transportation tool can be reduced, thereby meeting the transportation requirements in various situations while increasing the power generation capacity.

[0034] The inventors of this application have thought that in addition to the layout of the prime mover, generator and various auxiliary devices that can be optimized, the size and layout of the electrical system of the mobile power generation device can also be optimized, thereby reducing the size of the transportation tool for the mobile power generation device. On the other hand, when the mobile power generation device is transported to the designated scenario, the installation, repair and maintenance of the electrical system of the mobile power generation device are also relatively complex, thus reducing the usage efficiency of the mobile power generation device.

[0035] Based on this, the embodiments of the present disclosure provide an electrical system for a mobile power generation device and a mobile power generation device. The mobile power generation device includes a transportation vehicle and a generator; the electrical system includes: an electrical cabin disposed on the transportation vehicle; and a generator switch cabinet located within the electrical cabin and including generator switchgear configured to connect or disconnect the generator of the mobile power generation device from an external load. The generator switch cabinet further includes a first output terminal configured to be electrically connected to the external load through a connection conductor. The first output terminal includes a power connection terminal or a connector; the electrical cabin includes a first bottom plate on which the generator switch cabinet is disposed. The first bottom plate includes a first hollow portion, and the orthographic projection of the generator switch cabinet on the first bottom plate at least partially overlaps with the first hollow portion. The electrical system can electrically connect the first output terminal of the generator switch cabinet to the external load through the first hollow portion on the first bottom plate by disposing the first output terminal of the generator switch cabinet at the bottom of the electrical cabin, so that the first output terminal can be connected to the external load through the connection conductor by utilizing the distance between the electrical cabin on the transportation vehicle and the ground. Moreover, since the first output terminal of the generator switch cabinet is disposed at the bottom of the electrical cabin, the space occupied by the first output terminal in the electrical cabin can be reduced, and thus the space or volume of the electrical cabin can be reduced. Therefore, the electrical system can reduce the size of the electrical system and the difficulty of installation, inspection, and maintenance of the electrical system by optimizing the layout of the electrical system, so that the mobile power generation device adopting the electrical system can meet various transportation requirements while having a high power generation capacity, and can also improve the use efficiency of the mobile power generation device.

[0036] Next, the electrical system for a mobile power generation device and the mobile power generation device provided by the embodiments of the present disclosure will be described in detail with reference to the accompanying drawings.

[0037] An embodiment of the present disclosure provides an electrical system for a mobile power generation device. Figure 1 Schematic diagram of a mobile power generation device provided by an embodiment of the present disclosure; Figure 2 Planar schematic diagram of an electrical system for a mobile power generation device provided by an embodiment of the present disclosure; Figure 3 Side schematic diagram of an electrical system for a mobile power generation device provided by an embodiment of the present disclosure; Figure 4A and Figure 4B For an electrical cabin provided by an embodiment of the present disclosure at Figure 3 Bottom schematic diagram at the position of the dashed box AA in.

[0038] As shown in Figure 1 and Figure 2As shown, the mobile power generation device 200 includes a transportation vehicle 210 and a generator 220; the generator 220 can be used for power generation, and the transportation vehicle 210 can be used to carry and transport the generator 220 and the electrical system 100 for the mobile power generation device 200. The electrical system 100 includes an electrical cabin 110 and a generator switch cabinet 120; the electrical cabin 110 is arranged on the transportation vehicle 210, and the generator switch cabinet 120 is located within the electrical cabin 110 and includes generator switchgear 121; the generator switchgear 121 is used to connect or disconnect the generator 220 of the mobile power generation device 200 from an external load.

[0039] As Figure 3 shown, the generator switch cabinet 120 further includes a first output terminal 122; the first output terminal 122 is configured to be electrically connected to an external load through a connection conductor 301. The first output terminal 122 can be a terminal or a connector; the electrical cabin 110 includes a first bottom plate 111, and the generator switch cabinet 120 is arranged on the first bottom plate 111. For example, the generator switch cabinet 120 can be fixed on the first bottom plate 111.

[0040] As Figure 3 and Figure 4A shown, the first bottom plate 111 includes a first hollowed-out portion 1111, and the orthographic projection of the generator switch cabinet 120 on the first bottom plate 111 at least partially overlaps with the first hollowed-out portion 1111. That is to say, the generator switch cabinet 120 is arranged at the position where the first hollowed-out portion 1111 is located, and the first output terminal 122 can be exposed from the first bottom plate 111 through the first hollowed-out portion 1111 or can be located above the first hollowed-out portion 1111, and the connection conductor passes through the first hollowed-out portion 1111 to be connected to the first output terminal 122.

[0041] In the electrical system for a mobile power generation device provided in the embodiments of the present disclosure, since the electrical cabin 110 is arranged on the transportation vehicle 210, and there is a certain distance between the bearing surface or the girder of the transportation vehicle 210 and the ground, the electrical system 100 realizes the connection of the first output terminal 122 to an external load through the connection conductor 301 by arranging the first output terminal 122 of the generator switch cabinet 120 at the bottom of the electrical cabin 110, so as to utilize the distance between the electrical cabin 110 on the transportation vehicle 210 and the ground.

[0042] On the one hand, when the first output terminal of the generator switch cabinet is arranged on the side of the electrical cabin, the first output terminal will occupy a large space in the electrical cabin in consideration of factors such as the bending radius and safety spacing of the connecting conductor 301. However, the electrical system 100 provided in the embodiment of the present disclosure can reduce the space occupied by the first output terminal 122 in the electrical cabin 110 by arranging the first output terminal 122 of the generator switch cabinet 120 at the bottom of the electrical cabin 110, thereby reducing the space or volume of the electrical cabin 110.

[0043] On the other hand, when the first output terminal of the generator switch cabinet is set on the side of the electrical cabin, since there is a certain distance between the bearing surface or the bottom of the beam of the transport vehicle and the ground (for example, about 1.5 meters), the output terminal and the metal part of the transport vehicle 210 need to ensure a sufficient safety distance, so the position of the first output terminal may be high, and the installer needs a climbing tool to connect the connecting conductor to the first output terminal, resulting in low installation efficiency; and the climbing tool needs to be transported together, which increases the volume and weight of the mobile power generation device. However, since the distance between the bearing surface or the beam of the transport vehicle and the ground is just convenient for the installer to operate, the electrical system provided in the embodiment of the present disclosure uses the distance between the electrical cabin 110 on the transport vehicle 210 and the ground to realize the connection of the first output terminal 122 to the external load through the connecting conductor 301, thereby improving the installation efficiency. In addition, when inspection and maintenance are required, the inspection efficiency and maintenance efficiency of the electrical system can also be improved.

[0044] In summary, the electrical system can reduce the size of the electrical system and reduce the difficulty of installation, inspection and maintenance of the electrical system by optimizing the layout of the electrical system, so that the mobile power generation device using the electrical system can meet various transportation requirements while having a higher power generation capacity, and can also improve the use efficiency of the mobile power generation device.

[0045] In some examples, such as Figure 3 As shown, since the generator switch cabinet 120 is disposed on the first base plate 111 , the first output terminal 122 is also located at the bottom of the generator switch cabinet 120 .

[0046] In some examples, such as Figure 3 As shown, the first output terminal 122 may include a connector, so that it can be more convenient to connect to an external load. Of course, the first output terminal 122 may also include a connection terminal instead of a connector.

[0047] In some examples, such as Figure 3 , Figure 4A and Figure 4BAs shown, the electrical cabin 110 further includes a second bottom plate 112. The second bottom plate 112 is located on the side of the first bottom plate 111 away from the generator switch cabinet 120. The second bottom plate 112 includes a second hollow portion 1122. The orthographic projection of the first hollow portion 1111 on the second bottom plate 112 falls within the second hollow portion 1122. The electrical cabin 110 further includes a first cover plate 1125, which is movably connected to the second bottom plate 112 and covers the second hollow portion 1122. Thus, when the mobile power generation device is in transportation, as Figure 4B shown, the first cover plate 1125 can be in a closed state, covering the second hollow portion 1122, thereby preventing sundries such as water vapor and dust from entering the electrical cabin 110 or between the first bottom plate 111 and the second bottom plate 112; and when the mobile power generation device is transported to the designated position, as Figure 4A shown, the installer can open or move the first cover plate 1125, and connect the first output terminal 122 to the connection conductor through the second hollow portion 1122, so as to be connected to an external load.

[0048] In some examples, as Figure 3 shown, the second bottom plate 112 includes a central region 1120 and an edge portion 1121 located at the edge of the central region 1120. The central region 1120 of the second bottom plate 112 is spaced apart from the first bottom plate 111, and the edge portion 1121 of the second bottom plate 112 is fixedly connected to the edge of the first bottom plate 111.

[0049] In some examples, as Figure 3 and Figure 4A shown, the first output terminal 122 includes at least one power connection terminal 1220. The first bottom plate 111 includes at least one first hollow portion 1111, which is correspondingly arranged with at least one power connection terminal 1220; the second bottom plate 112 includes a second hollow portion 1122, and the orthographic projections of the first hollow portions 1111 on the second bottom plate 112 all fall within the second hollow portion 1122. That is to say, the size of the second hollow portion 1122 is larger, so as to facilitate the installer to install.

[0050] For example, as Figure 4A shown, the planar shape of each power connection terminal 1220 can be circular or rectangular, the planar shape of the first hollow portion 1111 can be circular or rectangular, and the planar shape of the second hollow portion 1122 can be rectangular. Of course, the embodiments of the present disclosure include but are not limited to this, and the planar shapes of the first hollow portion and the second hollow portion can be set according to actual needs.

[0051] In some examples, as Figure 4B shown, the first edge 1125A of the first cover plate 1125 is hinged to the second edge 1122A of the second hollow portion 1122. The first cover plate 1125 is configured to flip along the first edge 1125A, so as to facilitate the installer to operate.

[0052] For example, the above-mentioned hinge can be realized by hinge means such as a pivot shaft, a hinge chain, etc., and the embodiments of the present disclosure do not make specific limitations here. For example, the first cover plate can be connected to the second hollow part in other forms, and the first cover plate can move or fold relative to the second edge, so as to achieve the effect of opening the first cover plate.

[0053] In some examples, such as Figure 1 and Figure 2 As shown, the mobile power generation device 200 further includes a generator cabin 230. The electrical cabin 110 is adjacent to the generator cabin 230 and shares the first side plate 114; that is to say, the electrical cabin 110 and the generator cabin 230 are connected, and only one first side plate 114 is provided between the electrical cabin 110 and the generator cabin 230 for separation.

[0054] Figure 5 For Figure 2 an enlarged schematic view of the electrical system shown at the position of the dashed box BB. As Figure 2 and Figure 5 As shown, the generator switch cabinet 120 includes a first maintenance opening 123; the above-mentioned first side plate 114 includes a first opening 1141, the first opening 1141 is correspondingly arranged with the first maintenance opening 123, the orthographic projection of the first maintenance opening 123 on the first side plate 114 overlaps at least partially with the first opening 1141, and is configured to enable personnel to perform maintenance on the generator switch equipment 121 in the generator switch cabinet 120 through the first opening 1141 and the first maintenance opening 123. Therefore, the first opening 1141 and the first maintenance opening 123 have a certain area, and the overlapping area between the first opening 1141 and the first maintenance opening 123 is also relatively large (the overlapping area is more than 80% of the first maintenance opening 123), or even completely overlaps, so that personnel can enter. The electrical system 100 further includes a first maintenance partition 131, which is detachably installed on the first side plate 114 and blocks the first opening 1141.

[0055] Generally, since the equipment in the generator switch cabinet needs to be maintained, the generator switch cabinet needs to be provided with a maintenance entrance (whose function is similar to the first maintenance opening) and a maintenance door located on the maintenance entrance, and a maintenance passage for personnel to enter and exit also needs to be left outside the generator switch cabinet, thus occupying a relatively large space in the electrical cabin.

[0056] In the electrical system 100 provided in this example, the orthographic projection of the first maintenance opening 123 on the first side plate 114 at least partially overlaps with the first opening 1141, and the first maintenance partition 131 is detachably mounted on the first side plate 114 and covers the first opening 1141. Thus, when the mobile power generation device is operating normally, the first maintenance partition 131 can cover the first opening 1141, separating the electrical cabin 110 and the generator cabin 230, and at the same time realizing the separation and sealing of the electrical cabin 110 and the generator cabin 230. For example, an air conditioner can be installed in the electrical cabin 110 to control the temperature of the electrical cabin 110 between 25 degrees Celsius and 35 degrees Celsius, thereby providing favorable conditions for the heat dissipation and safe operation of the electrical equipment within the electrical cabin 110. When the mobile power generation device is being maintained or installed, personnel can utilize the maintenance space of the generator cabin 230 to enter the generator switch cabinet 120 from the generator cabin 230 and perform maintenance on the generator switch equipment 121 in the generator switch cabinet 120. Therefore, the electrical system 100 provided in this example can further reduce the volume or size of the electrical cabin 110, making the layout more compact, so that the mobile power generation device using this electrical system can meet various transportation requirements while having a high power generation capacity, and can also improve the utilization efficiency of the mobile power generation device.

[0057] It should be noted that since the shape of the generator 220 is usually irregular, and considering requirements such as safety, maintenance, wiring, air intake, and ventilation, the volume of the generator cabin 230 itself is much larger than the volume of the generator 220, so there is a relatively large maintenance space.

[0058] For example, as Figure 5 shown, the first maintenance partition 131 can be detachably mounted on the first side plate 114 by screws 1315 and cover the first opening 1141. Of course, the embodiments of the present disclosure include but are not limited to this, and the first maintenance partition can also be detachably mounted on the first side plate by other means.

[0059] In some examples, such as Figure 2As shown, the electrical system 100 may further include: a neutral point equipment cabinet 140, which is located within the electrical cabin 110 and includes a neutral point equipment 141. The neutral point equipment 141 is configured to be connected to the neutral point of the generator 220. The neutral point equipment cabinet 140 includes a second maintenance opening 143. The first side plate 114 includes a second opening 1142, which is correspondingly arranged with the second maintenance opening 143. The orthographic projection of the second maintenance opening 143 on the first side plate 114 at least partially overlaps with the second opening 1142. Similarly, the second opening 1142 and the second maintenance opening 143 are also configured to allow personnel to access the neutral point equipment 141 in the neutral point equipment cabinet 140 through the second opening 1142 and the second maintenance opening 143. Therefore, the second opening 1142 and the second maintenance opening 143 have a certain area, and the overlapping area between the second opening 1142 and the second maintenance opening 143 is also relatively large (the overlapping area is more than 80% of the second maintenance opening 143), or even completely overlaps, so that personnel can enter. The electrical system 100 further includes a second maintenance partition 132, which is detachably installed on the first side plate 114 and blocks the second opening 1142.

[0060] In the electrical system 100 provided in this example, the orthographic projection of the second maintenance opening 143 on the first side plate 114 at least partially overlaps with the second opening 1142, and the second maintenance partition 132 is detachably installed on the first side plate 114 and blocks the second opening 1142. Thus, when the mobile power generation device is operating normally, the second maintenance partition 132 can block the second opening 1142, separating the electrical cabin 110 and the generator cabin 230, and at the same time realizing the separation and sealing of the electrical cabin 110 and the generator cabin 230. When the mobile power generation device is being maintained or installed, personnel can utilize the maintenance space of the generator cabin 230 to enter the neutral point equipment cabinet 140 from the generator cabin 230 and perform maintenance on the neutral point equipment 141 in the neutral point equipment cabinet 140. Therefore, the electrical system 100 provided in this example can further reduce the volume or size of the electrical cabin 110, making the layout more compact, so that the mobile power generation device using this electrical system can meet various transportation requirements while having a high power generation capacity, and can also improve the use efficiency of the mobile power generation device.

[0061] In some examples, such as Figure 2As shown, the electrical system 100 further includes a starting equipment cabinet 150, which is located within the electrical cabin 110 and includes starting equipment 151 configured to start the prime mover 240. The first side plate 114 further includes a main body portion 1143 located between the first opening 1141 and the second opening 1142. The starting equipment cabinet 150 is disposed between the generator switch cabinet 120 and the neutral point equipment cabinet 140 and is adjacent to the main body portion 1143 of the first side plate 114.

[0062] Figure 6A and Figure 6B is an enlarged schematic view of the electrical cabin at the dashed box CC in Figure 3 provided by an embodiment of the present disclosure.

[0063] In some examples, as Figure 3 、 Figure 6A and Figure 6B shown, the electrical system 100 further includes an auxiliary power distribution cabinet 165, which is located within the electrical cabin 110 and includes auxiliary power distribution equipment 166 configured to supply power to auxiliary equipment; the auxiliary power distribution cabinet 165 further includes a second output terminal 1652 configured to be connected to the auxiliary equipment, and the second output terminal 1652 may include a terminal or a connector; the first bottom plate 111 includes a third hollow portion 1113, and the orthographic projection of the auxiliary power distribution cabinet 165 on the first bottom plate 111 at least partially overlaps with the third hollow portion 1113. That is to say, similar to the first output terminal 122, the second output terminal 1652 is also located at the bottom of the auxiliary power distribution cabinet 165 and can be connected to the auxiliary equipment through a connecting conductor 302.

[0064] In the electrical system for a mobile power generation device provided by the embodiments of the present disclosure, since the electrical cabin 110 is disposed on the transportation vehicle 210 and there is a certain distance between the bearing surface or the girder of the transportation vehicle 210 and the ground, the electrical system 100 can utilize the distance between the electrical cabin 110 on the transportation vehicle 210 and the ground to connect the second output terminal 1652 to the auxiliary equipment through the connecting conductor 302 by disposing the second output terminal 1652 of the auxiliary power distribution cabinet 165 at the bottom of the electrical cabin 110.

[0065] On the one hand, when the second output terminal of the auxiliary power distribution cabinet is disposed on the side of the electrical cabin, considering factors such as the bending radius and safety distance of the connecting conductor, the second output terminal will occupy a relatively large space within the electrical cabin. However, in the electrical system 100 provided by the embodiments of the present disclosure, by disposing the second output terminal 1652 of the auxiliary power distribution cabinet 165 at the bottom of the electrical cabin 110, the space occupied by the second output terminal 1652 in the electrical cabin 110 can be reduced, and thus the space or volume of the electrical cabin 110 can be reduced.

[0066] On the other hand, when the second output terminal of the auxiliary power distribution cabinet is set on the side of the electrical cabin, since there is a certain distance between the bearing surface or beam of the transport vehicle and the ground (for example, about 1.5 meters), the position of the second output terminal may be relatively high, and the installer needs a climbing tool to connect the connecting conductor to the second output terminal, resulting in low installation efficiency; and the climbing tool needs to be transported together, which increases the volume and weight of the mobile power generation device. However, since the distance between the bearing surface or beam of the transport vehicle and the ground is just convenient for the installer to operate, the electrical system provided in the embodiment of the present disclosure utilizes the distance between the electrical cabin 110 on the transport vehicle 210 and the ground to realize the connection of the second output terminal 1652 with the auxiliary equipment through the connecting conductor 302, thereby improving the installation efficiency. In addition, when inspection and maintenance are required, the inspection efficiency and maintenance efficiency of the electrical system can also be improved.

[0067] In some examples, such as Figure 3 , Figure 6A and Figure 6B As shown, the electrical cabin 110 further includes a second bottom plate 112, which is located on a side of the first bottom plate 111 away from the auxiliary power distribution cabinet 165, and the second bottom plate 112 includes a fourth hollow portion 1124, and the orthographic projection of the third hollow portion 1113 on the second bottom plate 112 falls into the fourth hollow portion 1124; the electrical cabin 110 may further include a second cover plate 1126, which is detachably connected to the second bottom plate 112 and covers the fourth hollow portion 1124. Therefore, when the mobile power generation device is being transported, Figure 6B As shown, the second cover plate 1126 can be in a closed state, covering the fourth hollow portion 1124, thereby preventing moisture, dust and other debris from entering the electrical cabin 110 or between the first bottom plate 111 and the second bottom plate 112; and when the mobile power generation device is transported to a designated location, such as Figure 6A As shown, the installer can open the second cover plate 1126 and connect the second output terminal 1652 to the connecting conductor through the fourth hollow portion 1124, thereby connecting to the auxiliary equipment.

[0068] In some examples, such as Figure 6A As shown, similarly, the second output terminal 1652 includes at least one power connection terminal 16520, the first bottom plate 111 includes a plurality of third hollow portions 1113, which are arranged one by one corresponding to the at least one power connection terminal 16520; the second bottom plate 112 includes a fourth hollow portion 1124, and the orthographic projections of the plurality of third hollow portions 1113 on the second bottom plate 112 all fall within the fourth hollow portion 1124. In other words, the size of the fourth hollow portion 1124 is relatively large, so that it is convenient for the installer to install.

[0069] For example, Figure 6AAs shown, the planar shape of each power connection terminal 16520 can be circular, the planar shape of the third hollow portion 1113 can be circular or rectangular, and the planar shape of the fourth hollow portion 1124 can be rectangular. Of course, the embodiments of the present disclosure include but are not limited to this, and the planar shapes of the third hollow portion and the fourth hollow portion can be set according to actual needs.

[0070] In some examples, as Figure 6B shown, the third edge 1126A of the second cover plate 1126 is hinged to the fourth edge 1124A of the fourth hollow portion 1124, and the second cover plate 1126 is configured to flip along the third edge 1126A, so as to facilitate the operation of the installer.

[0071] For example, the above-mentioned hinge can be realized by hinge methods such as a pivot shaft and a hinge chain, and the embodiments of the present disclosure do not make specific limitations here.

[0072] For example, the second cover plate can also be connected to the fourth hollow portion in other forms, and the second cover plate can be moved or folded relative to the fourth edge, so as to achieve the effect of opening the second cover plate.

[0073] In some examples, as Figure 2 shown, the electrical system 100 further includes an auxiliary power conversion cabinet 160. The auxiliary power conversion cabinet 160 is located within the electrical cabin 110 and includes auxiliary power conversion equipment 161. The auxiliary power conversion equipment 161 is configured to convert the first voltage output by the generator 220 into a second voltage. The electrical system 100 further includes an auxiliary power conversion switch device 162, which is located in the auxiliary power conversion equipment cabinet 160 and is configured to turn on or off the auxiliary power conversion equipment 161. Thus, after the auxiliary power conversion equipment 161 is configured to convert the first voltage output by the generator 220 into a second voltage, it can supply power to other auxiliary devices; and the auxiliary power conversion switch device 162 can turn on or off the auxiliary power conversion equipment 161. And since both the auxiliary power conversion equipment 161 and the auxiliary power conversion switch device 162 are arranged in the auxiliary power conversion cabinet 160, there is no need to separately set up a cabinet for placing the auxiliary power conversion switch, so as to improve the integration degree of the electrical cabin and reduce the volume of the electrical cabin.

[0074] In some examples, the auxiliary power conversion equipment 161 and the auxiliary power conversion switch device 162 are arranged in sequence in the auxiliary power conversion cabinet 160 in a direction perpendicular to the first bottom plate 111; the auxiliary power conversion equipment 161 is arranged below the auxiliary power conversion switch device 162, that is, the auxiliary power conversion equipment 161 is located on the side of the auxiliary power conversion switch device 162 close to the first bottom plate 111. Thus, although the height of the auxiliary power conversion cabinet 160 may increase, the area occupied by the auxiliary power conversion cabinet 160 remains unchanged, so as to achieve the improvement of the integration degree of the electrical cabin and the reduction of the volume of the electrical cabin.

[0075] For example, the output of the auxiliary power conversion device 161 can be connected to the auxiliary power distribution device 166 through a wire, so as to provide a power supply with a second voltage to the auxiliary devices through the auxiliary power distribution device 166.

[0076] In some examples, the auxiliary power conversion device 161 may include a transformer, and the first voltage is greater than the second voltage. For example, the first voltage may be 10KV - 20KV, and the second voltage may be 200V - 500V.

[0077] In some examples, as Figure 2 shown, the electrical system 100 further includes: an uninterruptible power supply cabinet 170, which is located within the electrical cabin 110 and includes an uninterruptible power supply device 171. The electrical system 100 further includes a storage battery 172, which is located within the uninterruptible power supply cabinet 170. Thus, the electrical system 100 integrates the uninterruptible power supply device 171 and the storage battery 172 in the same uninterruptible power supply cabinet 170, so that there is no need to separately set up a cabinet for placing the storage battery, thereby improving the integration degree of the electrical cabin and reducing the volume of the electrical cabin.

[0078] For example, the above-mentioned uninterruptible power supply device 171 can be an AC or DC uninterruptible power supply device. The uninterruptible power supply device 171 can provide power to the control devices, protection devices, etc. of the generator and the prime mover (such as a turbine engine) through the power distribution device 178, so as to control and protect the generator and the prime mover when the starting power supply and the power supply of the above-mentioned second voltage disappear.

[0079] In some examples, as Figure 1 and Figure 2 shown, the mobile power generation device 200 includes a prime mover 240; the electrical system 100 further includes: a generator control and protection cabinet 180 and a prime mover control and protection cabinet 190; the generator control and protection cabinet 180 is located within the electrical cabin 110 and includes a generator control and protection device 181, and the generator control and protection device 181 is configured to control and protect the generator 220; the prime mover control and protection cabinet 190 is located within the electrical cabin 110 and includes a prime mover control and protection device 191, and the prime mover control and protection device 191 is configured to control and protect the prime mover 240.

[0080] In some examples, as Figure 1 and Figure 2As shown, the electrical system 100 may further include: a satellite time synchronization device 182, a generator grid connection control device 183, and a closed-circuit television device 184. On the one hand, the satellite time synchronization device 182 can be used for time synchronization of the generator control and protection device 181 and the prime mover control and protection cabinet 190, facilitating the operation personnel to perform data analysis on the operating conditions and faults of the generator 200; the generator grid connection control device 183 can be used to parallel the generator 220 with other generators or connect it to the power grid in parallel; the closed-circuit television device 184 can be used for remote monitoring of the operating conditions and environmental conditions of the mobile power generation device or the devices outside the mobile power generation device.

[0081] For example, the above-mentioned satellite time synchronization device 182 can be a GPS time synchronization device or a Beidou time synchronization device; in addition, the above-mentioned satellite time synchronization device 182 can adopt hard-wired time synchronization or network time synchronization.

[0082] In some examples, as Figure 1 and Figure 2 shown, the mobile power generation device 200 includes a prime mover cabin 250, and the prime mover 240 is located in the prime mover cabin 250; the electrical system 100 further includes: a prime mover data acquisition box 195, configured to detect and display the operating parameters of the prime mover 240, and the prime mover data acquisition box 195 is disposed adjacent to the prime mover 240, for example, located within the prime mover cabin 240. Thus, the prime mover data acquisition module originally arranged in the electrical cabin 110 can be moved to the prime mover cabin 240, thereby reducing the volume of the electrical cabin 110.

[0083] An embodiment of the present disclosure also provides a mobile power generation device. Figure 1 It is a schematic diagram of a mobile power generation device provided by an embodiment of the present disclosure. As Figure 1 shown, the mobile power generation device 200 includes a transportation vehicle 210, a generator 220, and an electrical system 100. The generator 220 is located on the transportation vehicle 210, and the electrical system 100 is the electrical system of any one of the above. Thus, since the electrical system 100 reduces the size of the electrical system 100 and the difficulty of installation, overhaul, and maintenance of the electrical system 100 by optimizing the layout of the electrical system 100, the mobile power generation device 200 adopting the electrical system 100 can meet various transportation requirements while having a high power generation capacity, and can also improve the use efficiency of the mobile power generation device.

[0084] In some examples, as Figure 1As shown, the mobile power generation device 200 further includes a generator cabin 230, a prime mover cabin 250, and a prime mover 240; the generator cabin 230 is adjacent to the electrical cabin 110; the prime mover cabin 250 is located on the side of the generator cabin 230 away from the electrical cabin 110; the prime mover 240 is located within the prime mover cabin 250 and is configured to convert the chemical energy of fuel into mechanical energy; the prime mover 240 is connected to the generator 220, and the generator 220 is configured to convert the mechanical energy output by the prime mover 240 into electrical energy.

[0085] In some examples, the prime mover 240 includes a turbine engine, which not only has the advantages of small volume, light weight, high power density, etc., but also can use natural gas and wellhead gas as fuel, having greater economic and environmental benefits.
