Description

Technical Field

[0001] The invention relates to the field of power emergency repair, in particular to a plug-in generator quick access box and a system thereof. Background Art

[0002] At present, with the continuous improvement of social development, users' perception of electricity quality has also increased. When carrying out planned power maintenance operations or power outages caused by emergency repairs, it is necessary to ensure power supply to important places, special locations or some users. The power supply is generally guaranteed by connecting generators or power generation vehicles to the electrical equipment through the connection of generators or power generation vehicles to transmit electricity to them.

[0003] In the process of connecting the power supply, many uncertain factors may lead to prolonged power supply time; for example, when implementing power supply guarantee measures in some substations that are not equipped with low-voltage integrated distribution boxes or low-voltage switches, it is necessary not only to select a suitable deployment location, but also to ensure that the generator or generator vehicle will not be damaged due to excessive regional power load; at the same time, omissions in material selection may also cause on-site staff to have to travel back and forth between the unit and the construction site due to lack of necessary tools, which often results in a waste of 1 to 3 hours of time, especially on lines in rural and remote areas, this problem is more prominent; due to technical limitations, the power supply reliability indicators in these areas are affected, which in turn has a greater negative impact on customer satisfaction. Summary of the invention

[0004] Therefore, the technical problem to be solved by the present invention is that the existing power supply process takes a long time and has a significant negative impact on user satisfaction.

[0005] The above technical problem is solved by the following technical solution: The present invention proposes a plug-in generator quick access box, which includes a control cabinet, a self-adjusting air switch installed inside the control cabinet, an input interface connected to the self-adjusting air switch through a first copper busbar, an adjustment button for controlling the opening and closing of the self-adjusting air switch, an output interface connected to the self-adjusting air switch through a second copper busbar, and a mutual inductor arranged between the second copper busbar and the output interface;

[0010] The adjustment button can be adjusted to a corresponding gear position according to the amount of current, and a passage can be formed after the gear position is confirmed.

[0011] In a preferred embodiment of the plug-in generator quick access box of the present invention: the mutual inductor is arranged on a side close to the output interface;

[0012] The mutual inductor can help detect abnormal conditions and trigger corresponding protection actions to prevent damage to equipment or lines.

[0013] The beneficial effects of the present invention are as follows: the plug-in generator quick access box has the dual advantages of fixed installation or flexible movement, is easy to operate, safe and reliable, and cost-effective; the application of this equipment avoids the problem of temporarily finding a power connection point every time the power supply is guaranteed, and in areas where there is no low-voltage integrated distribution box or low-voltage air switch, there is no need to find a matching switch for protection and disconnection operations, and at the same time, it also reduces the time wasted on going back and forth between the site and the unit due to missing tools.

[0014] In addition, the technical problem to be solved by the present invention is: how to select an appropriate access branch according to the load of the user equipment.

[0015] The above technical problem is solved by the following technical solution: The present invention proposes a system for a plug-in generator quick access box, which includes a control unit, which evaluates the current demand and selects a suitable switch capacity to meet the requirements of the user equipment;

[0016] The self-adjusting air switches are available in different models of 100A, 200A, 400A and 630A;

[0017] Each group of self-regulating air switches of different capacities is connected in series selectively to ensure that only one switch suitable for the current user's equipment is involved in the circuit operation at a time.

[0018] In a preferred embodiment of the system of the plug-in generator quick access box of the present invention: the mutual inductor is connected in series on the current path from the self-regulating air switch to the output interface;

[0019] The secondary side of the transformer outputs a small current signal, which is connected to the control unit in the access box through a signal line.

[0027] In order to enable those skilled in the art to better understand the present invention, the present invention is further described in detail below in conjunction with specific implementation methods and drawings.

[0028] The terms used in the present invention are those general terms currently widely used in the art in consideration of the functions of the present invention, but these terms may vary according to the intention of a person of ordinary skill in the art, precedents, or new technologies in the art. In addition, specific terms may be selected by the applicant, and in this case, their detailed meanings will be described in the detailed description of the present invention. Therefore, the terms used in the specification should not be understood as simple names, but rather as a general description based on the meaning of the terms and the present invention.

[0029] Reference Figure 1 to Figure 3The present embodiment provides a plug-in generator quick access box, including a control cabinet 1, a self-regulating air switch 2 installed inside the control cabinet 1, an input interface 4 connected to the self-regulating air switch 2 through a first copper busbar 3, an adjustment button 5 for controlling the opening and closing of the self-regulating air switch 2, an output interface 8 connected to the self-regulating air switch 2 through a second copper busbar 6, and a mutual inductor 7 arranged between the second copper busbar 6 and the output interface 8; the self-regulating air switch 2 can be automatically disconnected according to the load amount to ensure circuit safety.

[0030] In this embodiment, the interior of the control cabinet 1 is a hollow structure, and the control cabinet 1 includes a cabinet body and a cabinet door; the interior of the counter is a hollow structure, and the control cabinet 1 is a rectangular structure; the side wall of the control cabinet 1 is provided with an input interface 4, and the input interface 4 extends to the interior of the control cabinet 1, and the input interface 4 is connected to the self-regulating air switch 2 through the first copper bus 3.

[0031] It should be noted that the input interface 4 can be connected to the generator via a connecting wire, so that the generator can transmit electricity to the inside of the access box via the connecting wire.

[0032] Furthermore, the self-regulating air switch 2 plays a key protective role in the power supply circuit and can automatically cut off the current when the load is too large, thereby preventing the line and equipment from being damaged.

[0033] Specifically, when the current in the circuit exceeds the preset safety threshold, the self-adjusting air switch will respond quickly and automatically disconnect the circuit to avoid problems such as overheating of wires, damage to insulation materials, or equipment failure due to overload.

[0034] It should be noted that the first copper bar 3 and the second copper bar 6 are both made of brass, which has good electrical conductivity and can ensure stability during power transmission.

[0035] It should be noted that the transformer 7 is installed on the circuit close to the user equipment side, and is mainly used for current measurement and protection functions; the transformer can convert the large current in the main circuit into a smaller secondary current at a certain ratio, so that ordinary measuring instruments such as ammeters, power meters, etc. can safely handle large current values ​​that originally exceed their range.

[0036] Specifically, transformers provide a way to monitor the current in a high-voltage circuit while maintaining the safety of the low-voltage side and avoiding the dangers of direct contact with the high voltage.

[0037] It should be noted that the output interface 8 is connected to the user device via a connecting line, and one end of the connecting line can be quickly connected to the output interface 8 by plugging; so that a connection can be quickly established between the access box and the user device, thereby shortening the time to build the line.

[0038] During use, when power supply is needed, the generator connection line is connected to the input interface, and the load end is also connected to the output interface 8 through the connection line. After the power plug is inserted into the box, the power end of the access box is automatically adjusted to the air switch position of the corresponding model through the operation screen control to carry out power supply work. The whole process is expected to take 10 to 15 minutes to complete; thereby shortening the working time and completing the power supply quickly.

[0039] As an optional embodiment, the input interface 4 includes a power access port, which is connected to the generator via a connecting wire adapted to the power access port, thereby enabling the generator to be quickly connected to the access box.

[0040] In this embodiment, the input interface 4 is connected to the connecting line in a quick-release manner. During the connection process, the plug head of the connecting line is inserted into the input interface 4, and then the other end of the connecting line is connected to the generator, so that the line connection can be quickly completed.

[0041] Specifically, the design of the power access port matches the connecting wire plug head to ensure that the generator can be quickly and safely connected to the access box; through this adaptive design, users can easily achieve efficient connection between the generator and the access box, thereby simplifying the power supply operation process and improving response speed.

[0042] In one embodiment provided in the present application, the output interface 8 includes a power output interface, which is connected to the user equipment via a connecting wire adapted to the power output interface, thereby enabling the user equipment to be quickly connected to the access box.

[0043] It should be noted that the input interface 8 is connected to the user equipment through an adapted connecting wire, and the connecting wire is equipped with a plug head matching the input interface 8, which can be quickly and safely connected to the output interface 8 of the access box. This design ensures the convenience, stability and reliability of the connection during the power supply process, and greatly improves the operational efficiency of the power supply.

[0044] In some embodiments, the self-adjusting air switch 2 is divided into multiple groups, and each group corresponds to a different gear; the adjustment button 5 can be adjusted to the corresponding gear according to the current, and a passage can be formed after the gear is confirmed.

[0045] In this embodiment, the opening and closing states of multiple groups of self-adjusting air switches 2 can be controlled by adjusting buttons, thereby achieving control of different gears and purposes, so that during the equipment adjustment process, the corresponding gear can be accurately selected according to the needs of the user's equipment.

[0046] Specifically, the self-regulating air switch is divided into multiple gear groups, each group corresponds to a specific current capacity. The adjustment button 5 allows the user to accurately select the corresponding gear according to the real-time current; once the gear is selected and confirmed, the corresponding self-regulating air switch will automatically close to ensure the safe connection of the circuit and provide a stable and controlled power transmission path.

[0047] As an optional embodiment, the mutual inductor 7 is arranged on a side close to the output interface 8; the mutual inductor 7 can help detect abnormal conditions and trigger corresponding protection actions to prevent damage to equipment or lines.

[0048] It should be noted that the transformer 7 is installed near the output interface 8 and is used to monitor the current situation in real time; when an abnormal current is detected, the transformer can trigger a corresponding protection mechanism and take protective actions in time to prevent damage to the equipment or line.

[0049] Specifically, the transformer 7 is arranged near the output interface 8 and is responsible for real-time monitoring of the current condition; once an abnormal current, such as overload or short circuit, is detected, the transformer will immediately trigger the protection mechanism and automatically perform the protection action to effectively prevent damage to the equipment and lines and ensure the safe operation of the power system.

[0050] Reference Figure 4 and Figure 5 This embodiment provides a system for a plug-in generator quick access box, including a control unit, which evaluates current demand and selects a suitable switch capacity to meet the requirements of user equipment; the self-regulating air switches 2 are switches of different models of 100A, 200A, 400A and 630A; each group of self-regulating air switches of different capacities are connected in series selectively to ensure that only one switch suitable for the current user equipment participates in the circuit operation at a time.

[0051] It should be noted that the control unit is preferably a microcontroller; it is responsible for real-time monitoring and evaluation of the current demand of the user equipment; it obtains current data through the mutual inductor 7 and other sensors, and determines the current capacity required currently based on these data.

[0052] Furthermore, based on the evaluation results, the control unit will select the most appropriate self-regulating air switch capacity to meet the requirements of the user's equipment. The access box is equipped with four different types of self-regulating air switches: 100A, 200A, 400A and 630A to adapt to different load conditions.

[0053] In this embodiment, each group of self-regulating air switches of different capacities are connected in series in a selective manner; this means that at the same time point, only one switch that best suits the current load conditions will be activated and participate in the circuit operation, while other unselected switches remain disconnected, waiting to be activated when needed next time.

[0054] Specifically, this design ensures that only one switch suitable for the current user device is involved in the circuit operation at a time, avoiding the complexity and potential risks of multiple switches working at the same time, and improving the safety and reliability of the system.

[0055] During use, when the user presses the start button on the operation screen, the signal is transmitted to the control unit; the control unit monitors the current situation in the current circuit through the mutual inductor, and according to the detected current demand, the control unit selects an appropriate self-regulating air switch capacity. Once the appropriate switch position is determined, the control unit issues a command to connect the corresponding air switch to the main circuit, forming a complete current path from the power side to the load side; if an overload or other abnormal situation is detected, the control unit will command the corresponding air switch to automatically trip and cut off the power supply to protect the equipment and lines; the status information of the self-regulating air switch is returned to the control unit through the feedback line, ensuring that the control system always understands the current working status and can make timely adjustments.

[0056] In summary, the control unit is not only responsible for evaluating the current demand and selecting the appropriate switch capacity, but also manages each group of self-regulating air switches of different capacities by selective series connection, ensuring that only one switch suitable for the current user's equipment is involved in the circuit operation at a time, thereby providing efficient, safe and reliable power supply.

[0057] As an optional embodiment, the transformer 7 is connected in series on the current path from the self-regulating air switch 2 to the output interface 8; the secondary side of the transformer 7 outputs a small current signal, and the signal is connected to the control unit in the access box through a signal line.

[0058] It should be noted that the transformer 7 is connected in series on the current path between the self-regulating air switch 2 and the output interface 8 for real-time monitoring of the current condition; the secondary side of the transformer outputs a small current signal, which is transmitted to the control unit in the access box through a dedicated signal line for precise current monitoring and protection control.

[0059] The transformer 7 is connected in series in the current path between the self-regulating air switch 2 and the output interface 8, and is responsible for real-time monitoring of current changes; the secondary side of the transformer outputs a small current signal, which is transmitted to the control unit in the access box through a dedicated signal line, ensuring that the control system can accurately obtain current data and achieve efficient monitoring and protection functions.

[0060] Finally, it should be pointed out that the methods and devices described in detail above are only embodiments, and those skilled in the art can modify these embodiments in different ways without departing from the scope of the present invention.
