Technical Field

[0001] The invention relates to the technical field of emergency power supply access, and in particular to an emergency power supply access box. Background Art

[0002] In today's society, the stability of power supply is crucial to people's production and life. Whether it is industrial production, commercial operations or daily household use, it is inseparable from continuous and reliable electricity. However, due to various unforeseen factors, such as natural disasters, equipment failures, power grid maintenance, etc., power outages occur from time to time.

[0003] In order to cope with these emergencies, emergency power supplies came into being. Existing emergency power supplies often have the defect of low switching efficiency when connected to the system. When the main power fails or is interrupted, the emergency power supply takes a certain amount of time to complete the switch and power the load. During this switching process, serious consequences such as equipment downtime, data loss, and even production interruption may occur.

[0004] Therefore, at present, when power outages are caused by power distribution equipment failure or flooding, the recovery method adopted during emergency repairs is usually to disconnect the fault point or flooding point, and then use a clamp to introduce the circuit into a mobile power supply, which is temporarily powered by the mobile power supply. However, since the fault point in some power rooms may be difficult or impossible to disconnect, and the installation of the clamp is inconvenient, it takes a lot of construction time, resulting in reduced switching power supply efficiency.

[0028] An embodiment of the present invention provides an emergency power supply access box, which is used to solve the technical problem that the fault points in some power rooms may be difficult or impossible to disconnect, the installation of the clamps is inconvenient, etc., which takes up a lot of construction time and leads to reduced switching power supply efficiency.

[0029] In order to make the purpose, features and advantages of the present invention more obvious and easy to understand, the technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the embodiments described below are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0030] See also Figure 1 , Figure 1 A structural block diagram of an emergency power access box provided in an embodiment of the present invention.

[0031] An emergency power access box provided by the present invention comprises at least one power access component 12 and at least one power switching component 13 accommodated in a box body 11 and electrically connected;

[0032] The power access component 12 is connected to different power supplies through two first inlet ports, and is connected to the power circuit 14 and / or the power switching component 13 through a single first outlet port;

[0033] The power switching component 13 is connected to the power circuit 14 and is used to switch the power supply of the power circuit 14 through a switch.

[0034] In this embodiment, the emergency power access box may include a box body 11 and at least one power access component 12 and at least one power switching component 13 accommodated in the box body 11 and electrically connected in sequence. The power access component 12 includes two first incoming ports and a single first outgoing port, the two first incoming ports are respectively connected to different power supplies such as power supply 1 and power supply 2, and the single first outgoing port is connected to a power circuit 14 and / or the power switching component 13 to provide reliable power support for the power circuit 14 or the power switching component 13. The second incoming port of the power switching component 13 can be connected to different power supplies such as power supply 3 and power supply 4, or the power access component 12 can be connected to one of the second incoming ports, such as Figure 1 As shown in the dotted part in the figure, the access connection represented by the dotted part has only a single connection.

[0035] If the power access component 12 is connected to the power switching component 13 through the single-channel first outlet port, the power switching component 13 can be directly connected to the power circuit 14 through a wire or circuit. When any power supply fails or a power outage occurs, the power supply of the power circuit 14 is switched through the switch on the power switching component 13.

[0036] If the power access component 12 is not connected to the power switching component 13 through the single-channel first outlet port, but is directly connected to the power circuit 14, the power switching component 13 is connected as a separate unit of the power circuit 14, and when the power access component 12 can provide power supply, the power switching component 13 can be in a completely disconnected state. If the power supply of the power access component 12 fails or the power is cut off, the power switching component 13 triggers the switch to close and switch the power supply to meet the power demand of the power circuit 14.

[0037] It should be noted that the power supply refers to a device that provides electrical energy to various electrical equipment, which may include but is not limited to AC power supply, backup power supply, renewable energy power supply or emergency power supply vehicle.

[0038] Optionally, the power switching component 13 is an independent functional module of modular design, which is used for parallel connection according to the scale of the power circuit 14 or the power supply.

[0039] like Figure 2As shown, it is a 1+2-bit splicing effect diagram and a 2+2-bit splicing effect diagram of the power switching component 13. In this embodiment, each power switching component 13 is an independent functional module with modular design, which can independently realize the switching of the power supply. Through the modularly designed power switching component 13, it can be based on the scale of the power circuit 14 or the power supply, such as the power equipment associated with the power circuit 14 is a high-load and high-voltage equipment, or the power supply scale of the power supply exceeds the preset size. At this time, by increasing or decreasing the number of modules, the power supply of public power supply circuits of different scales and needs can be quickly switched.

[0040] Each power switching component 13 includes an independent power switching circuit, which can be flexibly configured and expanded.

[0041] Optionally, the cable installation position of the power switching component 13 includes top-in and top-out or bottom-in and bottom-out.

[0042] In this embodiment, the power switching assembly 13 is designed with modular ideas and is splicable. Multiple power switching assemblies 13 can be spliced ​​together to form a larger power rapid switching system. By connecting the control circuits of different power switching assemblies 13, automatic switching and coordinated work between multiple power sources can be achieved. At the same time, considering the installation position of the cable, it can be freely converted to top-in and top-out, or bottom-in and bottom-out, etc., according to on-site demand solutions.

[0043] Optionally, a plurality of the power access components 12 are connected in parallel to the power circuit 14 or the power switching component 13 .

[0044] like Figure 3 As shown, Figure 3 It is a schematic diagram of the appearance structure of the power access component 12. In this embodiment, the red line of the power access component 12 is the live wire, which is connected to the high potential end of the power supply, provides AC voltage and current, and is the main line for transmitting electric energy in the circuit; the blue line is the neutral line, and its main function is to provide a loop so that the current can return to the power supply. Under normal circumstances, the potential of the neutral line is close to the earth potential. The yellow and green two-color lines are ground wires to connect the metal casing of the equipment to the earth. When the equipment has a fault such as leakage, the current can be conducted to the earth to prevent people from electric shock. The line color or purpose can be adjusted according to the actual use scenario of the power switching component 13, and the embodiment of the present invention does not limit this.

[0045] A single power access component 12 can be directly connected to the power circuit 14 and / or the power switching component 13. To increase the access current of the fast access point, multiple power access components 12 can be connected to the power circuit 14 or the power switching component 13 in parallel.

[0046] The maximum carrying current of a single power access component 12 is 630 A. Through the access of the power access component 12, it can withstand a current of 630 A, and the dual circuits can be connected in parallel to 1250 A.

[0047] Optionally, the power access component 12 is also used to loop out from the power circuit 14 to another power circuit 14 or a power receiving point of the power switching component 13 .

[0048] In this embodiment, in order to improve the flexibility of use of the power access component 12, the power access component 12 can be looped out to the next power receiving point that requires emergency power, and the mobile power supply can be easily connected to the public power supply circuit, which can quickly provide reliable power support for mobile devices.

[0049] See also Figure 4 , Figure 4 This is a circuit diagram of the power access component 12. By connecting the emergency mobile power supply to the first incoming line port of the power access component 12, the public power system can provide power energy to the user in a time-sharing manner. When the main power supply fails or the power goes out, the component can quickly connect to the mobile emergency power supply and supply it to the public power system, thus realizing the rapid access of the mobile power supply.

[0050] Optionally, the power switching component 13 includes two second inlet ports, a switch and a single second outlet port connected in sequence by wires;

[0051] The two second line inlet ports are respectively connected to at least two power supplies or the power access component 12 , and the single second line outlet port is connected to the power circuit 14 .

[0052] The two-input and one-output load isolation switch is used as the actuator, and the user's power supply cable is connected to the device. The modular design supports the use of one or two positions in parallel to achieve rapid switching of the public power supply circuit. When the main power supply fails or the power is cut off, the device can quickly connect the mobile emergency power supply to the power supply circuit to ensure the normal supply of public power.

[0053] Wherein, the switching switch is a two-input and one-output load isolation switch.

[0054] like Figure 5As shown, in this embodiment, the load isolation switch is connected to two different power inputs through two second inlet ports, which can usually be from different substations, generators or other power supply equipment. This allows two backup power supplies to be available when the power supply needs to be switched. The load device or power distribution system such as power circuit 141 and power circuit 142 is connected through a single second outlet port to output the selected power to the load. The outlet port usually has the same rated current and voltage level as the inlet port to ensure that power can be transmitted safely. At the same time, switching between the two inlet ports is performed through its switching mechanism, usually manually or electrically operated.

[0055] In addition, the switching mechanism also has a reliable locking function to prevent misoperation and ensure the accuracy of switching.

[0056] Optionally, the power supply includes a main power supply and an emergency power supply;

[0057] Optionally, the switching switch is used to trigger a switching action to switch to the emergency power supply when the main power supply fails or a power outage occurs.

[0058] The embodiment of the present invention provides an emergency power access box, which includes at least one power access component 12 and at least one power switching component 13 accommodated in a box body 11 and electrically connected; the power access component 12 is connected to different power supplies through two first inlet ports, and is connected to a power circuit 14 and / or a power switching component 13 through a single first outlet port; the power switching component 13 is connected to the power circuit 14, and is used to switch the power supply of the power circuit 14 through a switch. In this way, when the public power is interrupted, the backup power supply is quickly started and the power supply is restored, thereby greatly improving the stability and efficiency of the power supply.
