Description

Technical Field

[0001] The present invention belongs to the technical field of power distribution equipment, and in particular relates to an intelligent power distribution cabinet and an intelligent power distribution method. Background Art

[0002] The intelligent distribution cabinet integrates advanced sensor technology, communication technology and intelligent control algorithms. It can monitor parameters such as current, voltage, power and so on in real time, realize remote control and fault warning, effectively improve the stability and safety of the distribution system and reduce operation and maintenance costs.

[0003] At present, when the power distribution cabinet is working, it usually monitors the current, voltage and other parameters of each branch circuit in real time, and automatically adjusts the current distributed to each branch circuit when the load is detected to be overloaded, such as a monitoring method, device and power distribution cabinet of an intelligent power distribution cabinet disclosed in patent publication number CN116760197B;

[0004] When the distribution cabinet monitors the current and other parameters of each branch circuit, it is necessary to compare the monitored branch circuit parameters with the preset threshold parameters. When the monitored parameters exceed the threshold, some unnecessary branch circuits (such as air-conditioning systems, etc.) are disconnected to relieve the grid load and give priority to ensuring the normal operation of core equipment. However, the method of monitoring parameters and comparing them with preset parameters involves the conversion of multiple parameters, signal output, data comparison, etc., and the process is relatively complicated. In addition, the load threshold of the distribution cabinet is usually pre-set, but when the ambient temperature is high in summer, the temperature increase will increase the resistance of the cable conductor, affecting the load capacity of the grid. If it is still operated according to the preset load threshold, it may cause the distribution cabinet to be overloaded and increase the probability of line damage. Summary of the invention

[0018] S5. After the current data monitored by the current monitoring module electrically connected to each main branch module and received by the control module decreases, the control module controls each sub-branch circuit to be powered on again. If the control module receives the closing electrical signal of the electromagnetic switch again, the control module repeats step S4.

[0019] Compared with the existing technology, the advantages of an intelligent power distribution cabinet and an intelligent power distribution method are:

[0020] 1.

By taking into account the impact of the increase in ambient temperature on the load capacity of the power grid, the overload of the power grid can be accurately and effectively avoided, and the probability of circuit damage can be reduced.

[0021] 2.

[0022] 3. Through the cooperation of the gate valve, diversion hole, normally closed solenoid valve, installation sleeve and flow meter, based on the overload operation time of the distribution cabinet, when the overload times exceed the threshold, a maintenance signal can be automatically sent to the staff through the control module to avoid the normal operation of the distribution cabinet being affected by the overload operation time.

[0033] A current regulating mechanism 11 is installed on the side wall of each insulating plate 9, and each current regulating mechanism 11 includes a conductive strip 111 fixedly inserted into the side wall of the insulating plate 9. An insulating block 112 is integrally formed at the top of the magnetic isolation square tube 8 located on one side of the insulating plate 9, and a conductive block 113 is fixedly installed on the side wall of the insulating block 112. The conductive block 113 is in sliding contact with the side wall of the conductive strip 111, and an insulating elastic member is provided at the connection between the conductive block 113 and the insulating block 112 to ensure stable contact between the conductive block 113 and the conductive strip 111 and reduce the impact of wear.

[0034] A temperature regulating mechanism 12 is installed on the top of the cabinet 1, and an electromagnetic switch 13 is installed on the temperature regulating mechanism 12. The temperature regulating mechanism 12 includes an insulating support plate 121 fixedly installed on the top of the cabinet 1, and a thermistor 122 is fixedly plugged into the top of the insulating support plate 121. The electromagnetic switch 13 is fixedly arranged at the bottom of the insulating support plate 121. A plurality of conductive blocks 113 and conductive strips 111 are connected in series with the thermistor 122 and the electromagnetic switch 13. When the temperature of the thermistor 122 increases, its own resistance decreases.

[0035] Each current regulating mechanism 11 and temperature regulating mechanism 12 is connected in series with the electromagnetic switch 13. The cabinet 1 and the hollow plate 7 are jointly equipped with an air intake and heat dissipation mechanism 14. The air intake and heat dissipation mechanism 14 includes a mounting frame 141 fixedly mounted on the lower end of the outer wall of the cabinet 1, and a heat dissipation fan 142 is fixedly mounted inside the mounting frame 141. The cabinet 1 and the side wall of the hollow plate 7 are jointly provided with an air intake hole 143. The air outlet end of the heat dissipation fan 142 is connected to the hollow plate 7 through the air intake hole 143. The top of the hollow plate 7 is located above each insulating plate 9 and is provided with a plurality of conical holes 144. The upper end of the side wall of the cabinet 1 is provided with a plurality of heat dissipation holes 145. The air intake end of the heat dissipation fan 142 is installed with a filter screen, a moisture absorbent and other components (not shown in the figure) for reducing the intake of dust and moisture.

[0036] Each insulating plate 9 is equipped with a ventilation adjustment mechanism 15, and each ventilation adjustment mechanism 15 includes a conical plug 151 fixedly arranged on the top of each insulating plate 9, and the conical plug 151 is used to seal the conical hole 144 on the same side. A plurality of connecting frames 152 are fixedly installed inside the hollow plate 7, and a pressure switch 153 is fixedly installed at the end of each connecting frame 152. The moving contact of the pressure switch 153 is against the side wall of the connecting frame 152. The control module 6 adjusts the output power of the cooling fan 142 according to the number of disconnections of the pressure switch 153. The cooling fan 142 can be frequency-controlled. When the control module 6 receives one less closed electrical signal from the pressure switch 153, it will control the output power of the cooling fan 142 to increase by one gear.

[0037] A gate valve 16 is installed inside the hollow plate 7 near one side of the heat dissipation fan 142, and each magnetic isolation square tube 8 is arranged on one side of the gate valve 16. A diverter hole 17 is opened at the top of the hollow plate 7 between the gate valve 16 and the air inlet 143, and a normally closed solenoid valve 18 is installed inside the diverter hole 17. A mounting sleeve 19 connected to the diverter hole 17 is fixedly installed on the top of the hollow plate 7, and a flow meter 20 is fixedly installed on the side wall of the mounting sleeve 19. The detection end of the flow meter 20 is located directly above the diverter hole 17. The electromagnetic switch 13 is electrically connected to the normally closed solenoid valve 18, the gate valve 16 and the flow meter 20 through the control module 6. The flow meter 20 can measure the air passing through and transmit an electrical signal to the control module 6 after the measured flow reaches the set value. This is an existing mature technology, so it will not be elaborated here.

[0038] The operating principle of the present invention is now described as follows: the main incoming line module 2 is connected to the external power supply grid, and each main branch module 3 and each sub-branch module 4 are connected to the main incoming line module 2, and each current monitoring module 5 is connected to the corresponding main branch module 3 and sub-branch module 4, and then some non-essential equipment that can be disconnected when the main incoming line module 2 is overloaded (such as air-conditioning system, which will not affect the operation of core equipment after disconnection) is connected to the sub-branch module 4, and each core equipment (equipment that needs to be prioritized when the main incoming line module 2 is overloaded, such as servers, etc.) is connected to the main branch module 3, and the control module 6 is connected to each current monitoring module 5, the main branch module 3, and the sub-branch module 4;

[0039] Start the control module 6. When each terminal device uses electricity, each current monitoring module 5 can monitor the current output by each main branch module 3 and each sub-branch module 4. The control module 6 reduces the current monitored by each current monitoring module 5 in proportion (the proportion is set according to each terminal device connected to the main branch module 3 and the sub-branch module 4, usually 10:1) and then passes it into the corresponding electromagnetic strip 101. After the electromagnetic strip 101 is energized, it will generate magnetic attraction, thereby adsorbing the corresponding iron strip 103 to drive the magnetic isolation plate 102 and the insulating plate 9 to move downward. At this time, the contact position between the conductive strip 111 on the insulating plate 9 and the conductive block 113 on the same side moves upward relatively, thereby reducing the conductive strip 111 on the insulating plate 9. The length of the connection loop between the thermistor 122, the conductive strip 111, the conductive block 113 and the electromagnetic switch 13 is reduced, thereby reducing the overall resistance of the connection loop between the thermistor 122, the conductive strip 111, the conductive block 113 and the electromagnetic switch 13. If the power consumption of each terminal device exceeds the load, the downward movement distance of the conductive strip 111 corresponding to each terminal device that is using power is relatively large. At this time, when the overall resistance of the connection loop between the thermistor 122, the conductive strip 111, the conductive block 113 and the electromagnetic switch 13 drops below the threshold value (10 ohms), since the resistance drops below the threshold value, the current flowing into the electromagnetic switch 13 is large enough, so the moving contact of the electromagnetic switch 13 It will be magnetically closed immediately, and after receiving the closing electrical signal of the electromagnetic switch 13, the control module 6 will control the terminal devices electrically connected to the sub-branch module 4 to stop working in turn. Since some of the terminal devices connected to the sub-branch module 4 stop running or the operating power is reduced, the current output by the sub-branch module 4 is reduced. At this time, the current passed through the electromagnetic strip 101 corresponding to the sub-branch module 4 is synchronously reduced. Therefore, under the action of the spring 104, the magnetic isolation plate 102 and the insulating plate 9 on this side drive the conductive strip 111 to move back to its position, thereby making the connection circuit of the thermistor 122, the conductive strip 111, the conductive block 113 and the electromagnetic switch 13 complete. The body resistance becomes larger. When the resistance is higher than the threshold value, the current passed into the electromagnetic switch 13 is not enough to make the electromagnetic switch 13 magnetically close its own moving contact. At this time, the electrical signal of the electromagnetic switch 13 received by the control module 6 is disconnected, and then the control module 6 stops the action of stopping or reducing the power supply to the secondary branch module 4. Since the power consumption of the secondary branch module 4 is reduced, the operating load of the main incoming line module 2 becomes smaller, thereby avoiding the overload operation of the main incoming line module 2 and ensuring the stable operation of important equipment in each core. At the same time, after receiving the closing electrical signal of the electromagnetic switch 13, the control module 6 will send an alarm prompt information to the remote terminal through its own alarm module;

[0040] At the same time, if the ambient temperature is high, the resistance of the circuit inside the cabinet 1 increases. At this time, due to the high ambient temperature, the temperature at the thermistor 122 (the effective temperature detected by the thermistor 122 is between -10°C and 120°C. Within this temperature range, the resistance of the thermistor 122 decreases as the temperature increases) will also increase, thereby reducing the resistance of the thermistor 122. Therefore, when the ambient temperature is high, the overall resistance of the connection loop of the thermistor 122, the conductive strip 111, the conductive block 113 and the electromagnetic switch 13 will also decrease. Therefore, under the same power consumption, the electromagnetic switch 13 will be magnetically closed in advance when the ambient temperature is high, thereby avoiding the main incoming line module 2 from overloading when the ambient temperature is high.

[0041] After the current data monitored by the current monitoring module 5 electrically connected to each main branch module 3 received by the control module 6 decreases, the control module 6 controls each sub-branch circuit to be powered on again. If the control module 6 receives the closing electrical signal of the electromagnetic switch 13 again, the control module 6 repeats the steps of controlling each terminal device electrically connected to the sub-branch module 4 to stop working in sequence.

[0042] After the control module 6 is started, if a terminal device uses electricity, the electromagnetic strip 101 at this location will cooperate with the iron strip 103 to attract the insulating plate 9 at this location and drive the connecting frame 152 on the same side to move downward. When the connecting frame 152 moves downward and separates from the pressure switch 153 on this side, the moving contact of the pressure switch 153 on this side will immediately rebound and reset under the action of its own elastic element. At this time, the connection circuit between the control module 6 and the pressure switch 153 is in a disconnected state, so the control module 6 will lose the closing electrical signal of the pressure switch 153. At this time, the control module 6 will immediately control the cooling fan 142 to start working, and as the number of terminal devices using electricity increases, the number of connecting racks 152 that move downward increases. At this time, the control module 6 will lose more closing electrical signals of the pressure switches 153, and each time the control module 6 loses a closing electrical signal of a pressure switch 153, it will control the output power of the cooling fan 142 to increase by one gear, that is, when the control module 6 only loses a closing electrical signal of the pressure switch 153, the control module 6 controls the cooling fan 142 to increase by one gear. When the cooling fan 142 is working, the output power of the cooling fan 142 is the lowest. If the control module 6 loses all the closing electrical signals of the pressure switch 153, the control module 6 controls the cooling fan 142 to work at the highest gear. At this time, the output power of the cooling fan 142 is the largest. When the cooling fan 142 is working, it will convey airflow to the inside of the hollow plate 7 through the air inlet 143, and the airflow will be discharged through the conical hole 144 of the downward movement of the connecting frame 152. Since only the terminal equipment uses electricity, the connecting frame 152 on this side will move downward, so the air The airflow will dissipate heat for the main branch module 3 and the secondary branch module 4 corresponding to the terminal device that consumes electricity. Secondly, the greater the power consumption of the terminal device, the greater the downward movement distance of the connecting frame 152 at the corresponding position. At this time, the opening degree of the conical hole 144 on this side is greater, so more airflow will be discharged from the conical hole 144 here, so that the main branch module 3 and the secondary branch module 4 with large power consumption can be dissipated. Therefore, the heat dissipation airflow can be reasonably distributed and utilized, so that the heat in various areas inside the cabinet 1 can be dissipated in time;

[0043] At the same time, when the control module 6 receives the closing electrical signal of the electromagnetic switch 13, it means that the main incoming line module 2, the main branch module 3, the secondary branch module 4, etc. are all working under a large load state. After multiple load operations, the cables and other devices at the positions of the main incoming line module 2, the main branch module 3, the secondary branch module 4, etc. may be damaged (such as aging). Therefore, each time the control module 6 receives the closing electrical signal of the electromagnetic switch 13, it will control the gate valve 16 and the normally closed electromagnetic valve 18 to work until the closing electrical signal of the electromagnetic switch 13 received by the control module 6 disappears. When the gate valve 16 and the normally closed electromagnetic valve 18 are working, the airflow delivered by the heat dissipation fan 142 will be discharged through the diversion hole 17 and the installation sleeve 19. At this time, the airflow will pass through the flow meter 20, and the flow meter 20 can measure the air flow passing through. After the air flow measured by the flow meter 20 reaches the set value, it will output an electrical signal to the control module 6. Subsequently, the control module 6 will send an alarm signal to the remote terminal through its own alarm module, thereby reminding the staff to perform maintenance on the inside of the cabinet 1 in time.

[0044] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principle of the present invention should be included in the protection scope of the present invention.
