[0044] In the power management system, the power distribution cabinet can receive external power and distribute it according to the power-consuming equipment. When the power distribution cabinet is in use, the input element needs to receive external current and transmit it to the output element. Therefore, the maintenance personnel need to adjust the parameters of the power distribution cabinet or adjust the on and off of the input circuit according to the use requirements. However, in traditional power distribution cabinets, the installation positions of various input elements and various output elements are relatively scattered, which makes the location of the control switch relatively scattered, requiring maintenance personnel to use more complicated operations.

[0045] In view of this, the present application proposes a power distribution cabinet, which aims to solve the problem that the installation positions of various input components and various output components in traditional power distribution cabinets are relatively scattered, which leads to the relatively scattered positions of control switches, requiring maintenance personnel to use more complicated operations. Figures 1 to 5 are structural schematic diagrams of an embodiment of the power distribution cabinet proposed in the present application.

[0046] Please refer to Figure 1. The power distribution cabinet 100 proposed in this application includes a cabinet 1, an input module 2, an output module 3, a display module 4 and a monitoring module. An installation chamber 11 is provided inside the cabinet 1, and the input module 2 is installed in the installation chamber 11. The input module 2 is used to access external current. The output module 3 is installed in the installation chamber 11, and the output module 3 is connected to the input module 2 to output the current connected to the input module 2 to the outside world. The display module 4 is installed in the installation chamber 11, and the monitoring module is installed in the installation chamber 11. The monitoring module is electrically connected to the input module 2, the output module 3 and the display module 4 respectively. The monitoring module is used to monitor the current parameters of the input module 2 and the output module 3, and transmit the acquired current parameters to the display module 4 for display. Among them, the first direction M is the direction from the top of the cabinet 1 to the bottom of the cabinet 1, and the input module 2, the display module 4 and the output module 3 are arranged in the installation chamber 11 in sequence along the first direction M.

[0047] In the present application, the first direction M is a relative direction, and the first direction M can be set as a direction from the top of the cabinet 1 to the bottom of the cabinet 1 .

[0048] In the technical solution of the present application, each component in the power distribution cabinet 100 is modularly arranged. The power distribution cabinet 100 may specifically include an input module 2, an output module 3, a display module 4 and a monitoring module. The power distribution cabinet 100 can actually install the input module 2, the output module 3, the display module 4 and the monitoring module through the cabinet body 1, so that the installation of each component is more orderly. In addition, the input module 2, the display module 4 and the output module 3 are sequentially arranged in the installation chamber 11 along the first direction M, so that the position of the control switch corresponding to the input module 2 is relatively neat, which is convenient for maintenance personnel to use. In addition, the output interface corresponding to the output module 3 is also relatively neat, which is more convenient for the use of external equipment, and the display module 4 is located in the middle of the cabinet body 1, which is also convenient for maintenance personnel to observe.

[0049] In addition, when installing the power distribution cabinet 100, each component needs to be installed on the corresponding module first. After each module is installed, each module is installed at the corresponding position in the cabinet body 1, so that the installation and maintenance of each module are more convenient.

[0050] In some embodiments, the monitoring module includes a first monitor electrically connected to the input module 2, a second monitor electrically connected to the output module 3, and a controller electrically connected to the display module 4. The first monitor is configured to monitor a first power parameter of the input module 2, and the second monitor is configured to monitor a second power parameter of the output module 3. The controller is used to control the display module 4 to display the first power parameter and the second power parameter.

[0051] The monitoring part monitors the first electrical quantity parameter of the input module 2 through the first monitor, and monitors the second electrical quantity parameter of the output module 3 through the second monitor, so as to promptly prompt the maintenance personnel when an abnormality occurs in the input module 2 and the output module 3. In fact, the functions that the input module 2 and the output module 3 are responsible for are different when in use, so the first electrical quantity parameter is not the same as the second electrical quantity parameter. Specifically, the first electrical quantity parameter may include phase voltage, line voltage, current, temperature, neutral voltage, current imbalance, active power, reactive power, apparent power, power factor, frequency, bidirectional active and reactive electric energy, voltage / current total harmonic distortion rate and sub-harmonic content rate, circuit breaker status, lightning arrester status, etc. The second electrical quantity parameter may include voltage, current, micro-break opening and closing status, power, electric energy, demand, extreme value, harmonics, etc., and the first electrical quantity parameter and the second electrical quantity parameter can be adjusted according to actual needs.

[0052] Referring to FIGS. 2 to 5 , in some embodiments, the installation chamber 11 includes a first chamber 111, a second chamber 112, and a third chamber 113 that are sequentially connected along a first direction M, the input module 2 is installed in the first chamber 111, the display module 4 is disposed in the second chamber 112, and the output module 3 is disposed in the third chamber 113. The first monitor is installed in the first chamber 111 or the second chamber 112, and the second monitor is installed in the third chamber 113.

[0053] Specifically, the installation chamber 11 installs the input module 2 through the first chamber 111, the display module 4 through the second chamber 112, and the output module 3 through the third chamber 113. In addition, the specific structure of the first chamber 111 corresponds to the input module 2, the specific structure of the second chamber 112 corresponds to the display module 4, and the specific structure of the third chamber 113 corresponds to the output module 3, so that the input module 2, the display module 4 and the output module 3 are installed more smoothly.

[0054] Please refer to Figures 3 and 4. In some embodiments, the distribution cabinet 100 also includes strong wires and weak wires for connecting the input module 2 and the output module 3. The distribution cabinet 100 also includes a strong wire binding rack for installing the strong wires and a weak wire binding rack for installing the weak wires, and the strong wire binding rack 12 and the weak wire binding rack 13 are spaced apart so that the strong wires and the weak wires are spaced apart.

[0055] In specific applications, the strong wires of the power distribution cabinet 100 will power high-power devices, and the weak wires will power low-power devices. During power transportation, the strong wires and the weak wires may interfere with each other. In the present application, the power distribution cabinet 100 installs the strong wires through a strong wire binding rack, and installs the weak wires through a weak wire binding rack. Therefore, the power distribution cabinet 100 arranges the strong wire binding rack 12 and the weak wire binding rack 13 at intervals, so that the strong wires and the weak wires are arranged at intervals, thereby reducing the mutual interference between the strong wires and the weak wires.

[0056] In some embodiments, the input module 2 includes an input module 2 panel and a surge protector connected in parallel with the input module 2 panel. When the power distribution cabinet 100 is in normal use, the impedance of the surge protector will be very high, which makes the circuit where the surge protector is located similar to a circuit breaker, so that the circuit can normally supply power to the electrical devices. The voltage in the circuit will fluctuate. When the voltage exceeds the preset value, the resistance of the surge protector will drop sharply, so that the circuit where the surge protector is located becomes a passage, so that at least part of the current flows into the circuit where the surge protector is located, and flows into the ground after passing through the surge protector, avoiding damage to the electrical devices.

[0057] Please refer to FIG. 1 . In some embodiments, three output modules 3 are sequentially arranged along the first direction M, and each output module 3 is provided with 12 to 16 output terminals. In order to meet more output requirements, the power distribution cabinet 100 can be provided with three output modules 3. Specifically, in some embodiments of the present application, each output module 3 is provided with 12 to 16 output terminals, and each output terminal can be connected to an external line respectively. In fact, the number of output modules 3 can be adjusted according to actual needs, and the number of output terminals provided for each output module 3 can also be adjusted according to actual needs. For example, in one embodiment of the present application, the output module 3 is provided with 14 output terminals.

[0058] In some embodiments, the power distribution cabinet 100 further includes a main copper bar electrically connected to the input module 2, the main copper bar is located between the input module 2 and the output module 3, and is arranged along a first direction M toward the output module 3, so that the cables on the main copper bar can extend along the first direction M toward the output module 3, and be electrically connected to the output module 3. The first direction M is the relative direction of the output module 3 and the input module 2, and the main copper bar is arranged toward the first direction M, so that the wires connecting the input module 2 and the output module 3 can move directly along the first direction M, avoiding unnecessary detours of the wires, reducing consumables, and reducing the difficulty of installation.

[0059] In actual application, the positions of the input wires of the power distribution cabinet 100 may be different, and the positions of the output wires may also be different, which may result in the input wires and the output wires needing to extend out of the cabinet 1 and then detour a certain distance before they can be connected to the external wires, resulting in unnecessary consumables. Therefore, in some embodiments, the power distribution cabinet 100 is further provided with a plurality of input auxiliary copper bars and a plurality of output auxiliary copper bars for connecting with external cables, and a portion of the plurality of input auxiliary copper bars and the plurality of output auxiliary copper bars are arranged on one side of the installation chamber 11 in the first direction M, and the other portion is arranged on the other side of the installation chamber 11 in the first direction M.

[0060] Therefore, the power distribution cabinet 100 can have outgoing and incoming lines on both sides of the cabinet body 1, thereby making the wiring of the power distribution cabinet 100 more reasonable and reducing unnecessary consumption. In addition, the structure of the input auxiliary copper bar and the output auxiliary copper bar can be arranged according to the internal space of the cabinet body 1, thereby making the installation of the input auxiliary copper bar and the output auxiliary copper bar more convenient.

[0061] Please refer to Figures 1 and 5. In some embodiments, the display module 4 includes a display 41 and an alarm connected to each other. The display 41 is used to receive and display the current parameter transmitted by the monitoring module. The alarm is configured to alarm when the current parameter transmitted by the monitoring module exceeds a preset range. The display module 4 displays the current parameters of the input module 2 and the output module 3 through the display 41, and alarms when the current parameter exceeds the preset range through the alarm, thereby making the use of the power distribution cabinet 100 more intuitive and simple.

[0062] The present application also proposes a power management system, including the power distribution cabinet 100 as described in any of the above embodiments. The power management system can make its own installation and maintenance easier through the above power distribution cabinet 100, and can also make the operation easier and convenient for maintenance personnel. In addition, the power management system can make the line design more reasonable and reduce unnecessary material consumption through the above power distribution cabinet 100.

[0063] The technical features of the above-described embodiments may be arbitrarily combined. To make the description concise, not all possible combinations of the technical features in the above-described embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0064] The above-described embodiments only express several implementation methods of the present application, and the descriptions thereof are relatively specific and detailed, but they cannot be construed as limiting the scope of the patent application. It should be pointed out that, for a person of ordinary skill in the art, several variations and improvements can be made without departing from the concept of the present application, and these all belong to the protection scope of the present application. Therefore, the protection scope of the patent application shall be subject to the attached claims.
