Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of power distribution, and in particular to an intelligent power distribution box. BACKGROUND

[0002] The biggest difference between the intelligent power distribution box and the traditional power distribution box is whether it has the ability of automatic and intelligent monitoring. The traditional power distribution box can only realize the basic on-off control function and cannot monitor the running state of the power equipment in real time and remotely control. When the current, voltage and other data exceed the standard, it cannot send out a warning in time and take measures, resulting in damage to the power equipment and instability of the power system. At the same time, the ordinary power distribution box lacks real-time collection and analysis of power system data, and cannot effectively save energy and optimize management. In contrast, the intelligent power distribution box has strong intelligent control functions in automatic control, real-time power monitoring, remote control, energy saving and optimization.

[0003] However, in the related art, the number of controllable load circuits on the intelligent power distribution box is relatively fixed and cannot be changed, for example, the number of controllable load circuits cannot be increased. After the user purchases the intelligent power distribution box, as the number of power equipment increases, the intelligent power distribution box needs to provide more controllable load circuits to meet the control requirements of more power equipment. However, since the number of load circuits of the current intelligent power distribution box is fixed after leaving the factory, the current power distribution box cannot meet the user's demand for expanding the number of controllable load circuits.

The plurality of second controllable load circuits 23 are electrically connected to the second main circuit 24 respectively. The energy management module 30 is electrically connected to the first load metering board 10, and is used to control the plurality of first controllable load circuits 11. The energy management module 30 is further used to monitor or control the plurality of second controllable load circuits 23 after the first main circuit conducting member 13 and the second main circuit conducting member 21 are connected, and the first signal terminal 14 and the second signal terminal 22 are connected. Wherein, the first load metering board 10 is pre-installed in the smart distribution box 100. The second load metering board 20 is used to expand the number of controllable load circuits of the smart distribution box 100.

[0038] Specifically, the first load metering board 10 can be arranged in the smart distribution box 100 by screwing or clamping, so as to facilitate the installation and disassembly of the first load metering board 10. The first load metering board 10 can include a plurality of first controllable load circuits 11 and a first main circuit 12. The plurality of first controllable load circuits 11 can be respectively arranged on both sides of the first main circuit 12 and electrically connected with the first main circuit 12. The first load metering board 10 can further include a first main circuit conductive piece 13 and a first signal terminal 14. The first main circuit conductive piece 13 can be adapted to the second main circuit conductive piece 21 of the second load metering board 20, so as to realize the electrical connection between the first main circuit 12 and the second main circuit 24 on the second load metering board 20. The first signal terminal 14 can be adapted to the second signal terminal 22 on the second load metering board 20, so that the first load metering board 10 can be communicatively connected with the second load metering board 20. The second load metering board 20 can include a plurality of second controllable load circuits 23 and a second main circuit 24. The plurality of second controllable load circuits 23 can be respectively arranged on both sides of the second main circuit 24 and electrically connected with the second main circuit 24. It should be noted that the plurality of first controllable load circuits 11 can be, for example, 4, 6, 8, or 10, etc., without limitation. The plurality of second controllable load circuits 23 can be, for example, 4, 6, 8, or 10, etc., without limitation.

[0039] The energy management module 30 can be arranged in the smart distribution box 100 by clamping or screwing and located at one end of the first load metering board 10, so as to electrically connect the energy management module 30 with the first load metering board 10, so that the energy management module 30 can be used to control the plurality of first controllable load circuits 11, and to control the plurality of second controllable load circuits 23 after the first main circuit conductive piece 13 and the second main circuit conductive piece 21 are connected, and the first signal terminal 14 and the second signal terminal 22 are connected. That is, the energy management module 30 in the smart distribution box 100 can have the functions of electrical energy distribution and control, overload protection, short circuit protection, leakage protection, remote monitoring and control, electrical energy metering and data analysis, fault diagnosis and alarm, and intelligent management. It should be noted that the energy management module 30 can refer to an Engine Management System (EMS) module.

[0040] Further, the first load metering board 10 can be pre-installed in the smart distribution box 100, and the second load metering board 20 is used to expand the number of controllable load circuits of the smart distribution box 100. That is, the first load metering board 10 can be pre-installed in the smart distribution box 100 when it is factory-finished. After factory-finished, if the number of controllable load circuits on the first load metering board 10 cannot meet the user's needs in actual application, the second load metering board 20 can be installed in the smart distribution box 100 and electrically connected with the first load metering board 10 to expand the number of controllable load circuits in the smart distribution box 100, so that the user can increase the number of controllable load circuits according to the actual application situation to supply power to more loads, meeting the different needs of the user for the number of controllable load circuits of the smart distribution box 100.

[0041] For example, if the number of the first controllable load circuits 11 of the first load metering board 10 pre-installed in the smart distribution box 100 is 8, and the user needs 14 controllable load circuits in actual application, the user can install the second load metering board 20 with 6 controllable load circuits 23 in the smart distribution box 100 and electrically connect the second load metering board 20, so that the number of controllable load circuits in the smart distribution box 100 is expanded from 8 to 14, meeting the needs of the user for the number of controllable load circuits of the smart distribution box 100.

[0042] In this way, the smart distribution box 100 of the embodiment of the present application can expand the second load metering board 20 including a plurality of second controllable load circuits 23 on the basis of pre-installing the first load metering board 10 in the smart distribution box 100 by connecting the second signal terminal 22 of the second load metering board 20 with the first signal terminal 14, so that the user can increase the number of controllable load circuits according to the actual application situation to supply power to more loads, meeting the different needs of the user for the number of controllable load circuits of the smart distribution box 100.

[0043] Please refer to Figure 3 and Figure 5 In some embodiments, the first main circuit conductive member 13 is arranged on the first main circuit 12. The second main circuit conductive member 21 is arranged on the second main circuit 24. After the first main circuit conductive member 13 is connected with the second main circuit conductive member 21, the first main circuit 12 and the second main circuit 24 are conducted.

[0044] Specifically, the first main circuit conductor 13 can be arranged on the first main circuit 12 by way of integral molding, and the second main circuit conductor 21 can also be arranged on the second main circuit 24 by way of integral molding, so as to reduce the production cost. It should be noted that the first main circuit 12 and the second main circuit 24 can both be copper bars. That is, the first main circuit conductor 13 and the second main circuit conductor 21 can be electrical connection ends on the copper bars.

[0045] In one embodiment, as shown in FIG. 1, after the first main circuit conductor 13 is connected with the second main circuit conductor 21, the first main circuit 12 and the second main circuit 24 are made conductive, so as to realize electrical connection between the first load metering board 10 and the second load metering board 20, and further expand the number of controllable load circuits in the intelligent distribution box 100. Figure 5

[0046] In some embodiments, the first main circuit conductor 13 is connected with the second main circuit conductor 21 by screwing or clamping. That is, the first main circuit conductor 13 and the second main circuit conductor 21 can be provided with corresponding screw holes or clamping portions. When the user needs to expand the number of controllable load circuits in the intelligent distribution box 100, the first main circuit conductor 13 can be connected with the second main circuit conductor 21 by screwing through the screw holes or by clamping through the clamping portions, so as to facilitate installation and disassembly of the first main circuit conductor 13 and the second main circuit conductor 21.

[0047] Please refer to Figure 2 , Figure 4 and Figure 5 In some embodiments, the first signal terminal 14 is fixed to the first load metering board 10, and the second signal terminal 22 is fixed to the second load metering board 20.

[0048] ​That is, in one embodiment, the first signal terminal 14 can be arranged on one end of the first load metering board 10 by screwing or welding, so that the first signal terminal 14 is fixedly arranged on the first load metering board 10. The second signal terminal 22 can be arranged on one end of the second load metering board 20 close to the first signal terminal 14 by screwing or welding, so that the second signal terminal 22 is fixedly arranged on the second load metering board 20 while facilitating the connection of the first signal terminal 14 to the second signal terminal 22 by a wire, so that after the connection of the first signal terminal 14 to the second signal terminal 22, the energy management module 30 is communicatively connected to the plurality of second controllable load circuits 23.

[0049] In another embodiment, the first signal terminal 14 can be arranged on one end of the first load metering board 10 by screwing or welding, so that the first signal terminal 14 is fixedly arranged on the first load metering board 10. The second signal terminal 22 can be connected to the second load metering board 20 by a wire, so that the second signal terminal 22 can be flexibly adjusted in position to connect to the first signal terminal 14 according to actual installation needs, so that after the connection of the first signal terminal 14 to the second signal terminal 22, the energy management module 30 is communicatively connected to the plurality of second controllable load circuits 23.

[0050] In yet another embodiment, the second signal terminal 22 can be arranged on one end of the second load metering board 20 by screwing or welding, so that the second signal terminal 22 is fixedly arranged on the second load metering board 20. The first signal terminal 14 can be connected to the first load metering board 10 by a wire, so that the first signal terminal 14 can be flexibly adjusted in position to connect to the second signal terminal 22 according to actual installation needs, so that after the connection of the first signal terminal 14 to the second signal terminal 22, the energy management module 30 is communicatively connected to the plurality of second controllable load circuits 23.

[0051] In this way, the intelligent power distribution box 100 of the embodiments of the present application provides a plurality of installation and connection modes in which the first signal terminal 14 is installed on the first load metering board 10 and the second signal terminal 22 is installed on the second load metering board 20, so that the user can select a more convenient installation and connection mode when expanding the number of controllable load circuits, realize the connection of the first signal terminal 14 to the second signal terminal 22, and ensure that the energy management module 30 is communicatively connected to the plurality of second controllable load circuits 23 while facilitating on-site installation and avoiding excessive and complex operations.

[0052] In addition, as Figure 3As shown, the first signal terminal 14 may include a communication connector 141. The second signal terminal 22 may include a signal line 221 and a terminal 223 disposed on the signal line 221. The signal line 221 can be electrically connected to the communication connector 141 through the terminal 223, thereby ensuring that the energy management module 30 can communicate with multiple second controllable load circuits 23, while facilitating on-site installation without excessive complex operations.

[0053] Please see Figure 2 and Figure 4 In some embodiments, there are two first load metering boards 10 and two first main circuits 12, arranged side-by-side, with the two first load metering boards 10 positioned opposite each other on either side of the two first main circuits 12. There are also two second load metering boards 20 and two second main circuits 24, arranged side-by-side, with the two second load metering boards 20 positioned opposite each other on either side of the two first main circuits 12. That is, the number of first load metering boards 10 can correspond to the number of first main circuits 12, the two first main circuits 12 can be arranged side-by-side, and the two first load metering boards 10 can be positioned opposite each other on either side of the two first main circuits 12, so that the plurality of first controllable load circuits 11 on the first load metering board 10 are respectively electrically connected to the first main circuit 12. The number of second load metering boards 20 can also correspond to the number of second main circuits 24. Two second main circuits 24 can be arranged side by side, and two second load metering boards 20 can be arranged opposite each other on both sides of the two second main circuits 24, so that multiple second controllable load circuits 23 on the second load metering board 20 are electrically connected to the second main circuits 24 respectively.

[0054] In addition, such as Figure 2 As shown, the first load metering board 10 also includes a first conductive element 16, a first bracket 17, and a first current transformer 18 disposed on the first bracket 17. The first conductive element 16 includes a first conductive sheet 161 and a second conductive sheet 163. One end of the first conductive sheet 161 and the second conductive sheet 163 are both disposed on the first load metering board 10. The other end of the first conductive sheet 161 can be electrically connected to the first main circuit 12, and the other end of the second conductive sheet 163 can pass through the first bracket 17 and be connected to the first current transformer 18. It should be noted that the first current transformer 18 can achieve high-precision measurement of the current of the first controllable load circuit 11, enabling the energy management module 30 to more accurately control the first controllable load circuit 11.

[0055] Please see Figure 2 In some embodiments, a receiving space 40 is formed within the intelligent distribution box 100. The first load metering plate 10 is fixedly installed within the receiving space 40 by screwing or snap-fitting. That is, as... Figure 1As shown, the accommodation space 40 can be provided with a mounting portion 41 corresponding to the first load metering plate 10, so that the first load metering plate 10 can be fixedly installed in the accommodation space 40 by the mounting portion 41 in a screwing manner or a clamping manner, to facilitate the installation and disassembly of the first load metering plate 10.

[0056] Please refer to Figure 2 and Figure 3 In some embodiments, the first load metering plate 10 further comprises a first load metering shell 19, which is detachably installed in the accommodation space 40 after being covered on the first load metering plate 10. That is, after the first load metering plate 10 is installed in the accommodation space 40, the first load metering shell 19 can be detachably fixedly installed in the accommodation space 40 in a buckling manner after being covered on the first load metering plate 10, to facilitate the installation and disassembly of the first load metering shell 19, while the first load metering shell 19 can also effectively shield the first load metering plate 10 from dust and other pollutants. It should be noted that the first load metering shell 19 can be made of plastic or metal. That is, when the first load metering shell 19 is made of plastic, the production cost can be reduced. When the first load metering shell 19 is made of metal, for example, aluminum alloy, the service life of the first load metering shell 19 can be prolonged while the weight of the first load metering shell 19 is reduced.

[0057] Please refer to Figure 4 and Figure 6 In some embodiments, the second load metering plate 20 further comprises a second load metering shell 29. The second load metering plate 20 is fixedly installed in the second load metering shell 29 in a screwing or clamping manner. The second load metering shell 29 is detachably installed in the accommodation space 40 and located on one side of the first load metering plate 10. That is, the second load metering plate 20 can be fixedly installed in the second load metering shell 29 in a screwing or clamping manner, so that the second load metering shell 29 can play a role in shielding and protecting the second load metering plate 20. The second load metering shell 29 can be formed with screwing holes or clamping portions. When the second load metering plate 20 is fixedly installed in the second load metering shell 29, the second load metering shell 29 can be detachably installed in the accommodation space 40 in a screwing manner through the screwing holes or in a clamping manner through the clamping portions and located on one side of the first load metering plate 10 (as shown in Figure 5

[0058] ​It should be noted that the second load metering board 20, when arranged in the second load metering shell 29, the second main circuit electrically conductive piece 21 and the second signal terminal 22 can be partially exposed outside the second load metering shell 29, so as to facilitate the connection of the second main circuit electrically conductive piece 21 with the first main circuit electrically conductive piece 13, and the communication connection of the second signal terminal 22 with the first signal terminal 14.

[0059] The accommodation space 40 can further be provided with a limiting part 43. When the second load metering shell 29 is installed in the accommodation space 40, the limiting part can limit the second load metering shell 29, so that the second load metering shell 29 is more firmly installed in the accommodation space 40. The second load metering shell 29 can be made of plastic or metal. That is, when the second load metering board 20 shell is made of plastic, the production cost can be reduced. When the second load metering board 20 shell is made of metal, for example, can be made of aluminum alloy, so as to prolong the service life of the second load metering board 20 shell while reducing the weight of the second load metering board 20 shell.

[0060] In some embodiments, the second load metering shell 29 includes a bottom shell 291 and a cover plate 293. The second load metering board 20 is installed on the bottom shell 291. The cover plate 293 is arranged on the second load metering board 20 and detachably connected with the bottom shell 291.

[0061] Specifically, as shown in Figure 6 The second load metering shell 29 can include a bottom shell 291 and a cover plate 293. The bottom shell 291 can be formed with an installation space 295. The second load metering board 20 can be installed on the bottom shell 291 in the installation space 295 by clamping or screwing. The second load metering board 20 further includes a second electrically conductive piece 26, a second bracket 27 and a second transformer 28 arranged on the second bracket 27. The second electrically conductive piece 26 includes a third electrically conductive piece 261 and a fourth electrically conductive piece 263.

The cover plate 293 can be arranged on the second load metering board 20 and detachably connected with the bottom shell 291 by clamping or screwing, so that the cover plate 293 and the bottom shell 291 cooperate to set the second load metering board 20 in a relatively closed space to protect the second load metering board 20. It should be noted that the second transformer 28 can realize high-precision measurement of the current of the second controllable load circuit 23, so that the energy management module 30 can more accurately control the second controllable load circuit 23. The bottom shell 291 can be provided with heat dissipation holes 297, so that the second load metering board 20 can dissipate heat through the heat dissipation holes 297 when working.

[0062] Please combine Figure 1 , Figure 3 and Figure 7 In some embodiments, a receiving space 40 is formed in the smart distribution box 100. The smart distribution box 100 further comprises an inner door plate 50 and a movable door plate 60. The energy management module 30, the first load metering plate 10 and the second load metering plate 20 are sequentially installed in the receiving space 40. The inner door plate 50 and the movable door plate 60 are sequentially arranged on the receiving space 40 and cover the energy management module 30, the first load metering plate 10 and the second load metering plate 20 installed in the receiving space 40. The inner door plate 50 is provided with a first hole site 51 and a second hole site 53 spaced from the first hole site 51. The first load metering plate 10 further comprises a first circuit breaker 101 exposed from the inner door plate 50 through the first hole site 51. The second load metering plate 20 comprises a second circuit breaker 201 exposed from the inner door plate 50 through the second hole site 53 when the second load metering plate 20 is installed in the receiving space 40.

[0063] Specifically, a receiving space 40 can be formed in the smart distribution box 100. The energy management module 30, the first load metering plate 10 and the second load metering plate 20 can be sequentially installed in the receiving space 40 along the length direction of the smart distribution box 100 in a screwing or clamping manner, so as to facilitate the installation and disassembly of the energy management module 30, the first load metering plate 10 and the second load metering plate 20.

[0064] The smart distribution box 100 can further comprise an inner door plate 50 and a movable door plate 60. After the energy management module 30, the first load metering plate 10 and the second load metering plate 20 are sequentially installed in the receiving space 40, the inner door plate 50 and the movable door plate 60 can be sequentially arranged on the receiving space 40 and cover the energy management module 30, the first load metering plate 10 and the second load metering plate 20 installed in the receiving space 40 in a clamping or screwing manner, so as to protect the energy management module 30, the first load metering plate 10 and the second load metering plate 20 in a relatively closed space, and prevent external dust and other pollutants from polluting the energy management module 30, the first load metering plate 10 and the second load metering plate 20. It should be noted that the inner door plate 50 and the movable door plate 60 can be made of plastic or metal. That is, when the inner door plate 50 and the movable door plate 60 are made of plastic, the production cost can be reduced. When the inner door plate 50 and the movable door plate 60 are made of metal, for example, aluminum alloy, the service life of the inner door plate 50 and the movable door plate 60 can be prolonged, and the weight of the inner door plate 50 and the movable door plate 60 can be reduced.

[0065] As Figure 1 and Figure 8As shown, the inner door plate 50 is provided with a first hole position 51 and a second hole position 53 which is spaced apart from the first hole position 51 by a pre-set distance. The first load metering plate 10 further comprises a first circuit breaker 101. The first circuit breaker 101 can be connected with one end of the second conductive sheet 163 which passes through one end of the first current transformer 18. The first circuit breaker 101 can be exposed from the inner door plate 50 through the first hole position 51, so that the inner door plate 50 can play a role of shielding the first load metering plate 10, and at the same time, it can facilitate the user to control the shutdown of the first circuit breaker 101. The second load metering plate 20 can comprise a second circuit breaker 201, and the second circuit breaker 201 can be connected with one end of the fourth conductive sheet 263 which passes through the second current transformer and extends from the circuit breaker mounting slot 2931 of the second cover plate 293. When the second load metering plate 20 is installed in the accommodation space 40, the second circuit breaker 201 can be exposed from the inner door plate 50 through the second hole position 53, so that the inner door plate 50 can play a role of shielding the second load metering plate 20, and at the same time, it can facilitate the user to control the shutdown of the second circuit breaker 201. It should be noted that the circuit breaker mounting slot 2931 of the second cover plate 293 can be arranged at a position corresponding to the second current transformer 28, so that the fourth conductive sheet 263 can directly extend from the circuit breaker mounting slot 2931 to connect with the second circuit breaker 201 after passing through the second current transformer 28, while also playing a role of limiting the second circuit breaker 201.

[0066] Further, the first hole position 51 and the second hole position 53 can refer to the position where the knock-out hole is arranged, that is, when the first circuit breaker 101 does not pass through the first hole position 51 or the second circuit breaker 201 does not pass through the second hole position 53 to be exposed from the inner door plate 50, the baffle on the first hole position 51 and the second hole position 53 can be in a closed state, and the user can decide to knock down the baffle on several first hole positions 51 or second hole positions 53 to form several knock-out holes according to the actual required controllable load path number. For example, when the user does not need to select the second load metering plate 20 to be installed later, then when installing the intelligent power distribution box 100, only the baffle on the first hole position 51 corresponding to the first load metering plate 10 can be knocked down to form the knock-out hole corresponding to the first circuit breaker 101, while the baffle on the second hole position 53 corresponding to the second load metering plate 20 can be selected to be retained, so as to ensure that the unused second load metering plate 20 will not be polluted by dust and pollutants, and at the same time, it is more beautiful. It should be noted that each first hole position 51 can correspond to one or more first circuit breakers 101, and each second hole position 53 can correspond to one or more second circuit breakers 201, which is not limited herein.

[0067] In some embodiments, the second load metering board 20 is an optional accessory. That is, in the present application, the user can choose whether to install the second load metering board 20 in the intelligent power distribution box 100 according to the actual application needs, so as to increase or reduce the number of controllable load circuits, thereby meeting the different needs of the user for the number of controllable load circuits of the intelligent power distribution box 100.

[0068] The above embodiments only express several embodiments of the present application, which are described in detail and specifically, but cannot be understood as the limitation of the patent scope of the present application. It should be pointed out that for ordinary skilled in the art, without departing from the concept of the present application, several modifications and improvements can be made, which all belong to the protection scope of the present application. Therefore, the protection scope of the patent of the present application should be subject to the appended claims.
