DETAILED DESCRIPTION

[0025] The detailed description of the drawings is intended as an illustration of the current embodiment of the present application, and is not intended to represent the only form in which the present application can be implemented. It should be understood that the same or equivalent functions can be accomplished by different embodiments intended to be included in the spirit and scope of the present application.

[0026] See also Figures 1 to 4 The embodiment of the present invention provides a low-voltage bypass power generation quick access branch box, comprising:

[0027] The incoming line socket access port is used to connect the power supply vehicle and realize quick connection through the quick connection plug; specifically, the incoming line socket access port is an interface of the branch box, which is used to connect the power supply vehicle. By using the quick connection plug, the power supply vehicle and the branch box can be quickly connected, thereby simplifying the wiring process and improving the efficiency and safety of wiring.

[0028] The outlet socket access port is used to connect the low-voltage switch and realizes quick connection through the quick connection plug; specifically, the outlet socket access port is another interface of the branch box, which is used to connect the low-voltage switch. The quick connection plug is also used to make the connection with the low-voltage switch faster and more convenient.

[0029] The three-phase busbar and the N-phase busbar are used to connect the incoming socket access port and the outgoing socket access port, and the surfaces of the three-phase busbar and the N-phase busbar are tin-plated; specifically, the three-phase busbar and the N-phase busbar are conductive components inside the branch box, which are used to connect the incoming socket access port and the outgoing socket access port. The surfaces of the three-phase busbar and the N-phase busbar are tin-plated, which helps to improve their conductivity and reduce resistance, while also preventing oxidation and extending their service life.

[0030] The circuit breaker is arranged on the three-phase busbar and is used to automatically cut off the current after the current exceeds the trip setting; specifically, the circuit breaker is installed on the three-phase busbar, and its function is to automatically cut off the current when the current in the circuit exceeds the preset safety value, thereby protecting the circuit and equipment from overload damage and improving the safety of the system.

[0031] The grounding terminal is used for grounding the right side of the branch box; specifically, the grounding terminal is located on the right side of the branch box and is used to ground the branch box. Grounding is an important measure for electrical safety, which can prevent electrical equipment from being energized due to leakage and ensure the safety of operators.

[0032] The three-phase incoming power indicator light is used to determine the access status of the power incoming and outgoing lines; specifically, the three-phase incoming power indicator light is an indicator device used to display whether the incoming and outgoing lines of the power have been correctly connected. By observing the status of the indicator light, the operator can quickly determine whether the power connection is successful.

[0033] The digital display is used to display the values ​​of working current and voltage, so that operators can monitor the operating status of the power system in real time, facilitating power management and maintenance.

[0034] The casters, including two universal wheels and two wheels with locking mechanisms, are used to realize the movement of the branch box; specifically, the universal wheels provide flexible steering capabilities, while the wheels with locking mechanisms can be locked when the position of the branch box needs to be fixed to prevent movement.

[0035] In summary, the embodiments of the present invention provide a low-voltage bypass power generation quick access branch box with compact structure, easy operation and high safety, which is particularly suitable for occasions where power needs to be deployed quickly, such as construction sites, emergency power supply, etc.

[0036] Furthermore, the incoming line socket access port includes a three-phase incoming line socket access port and an N-phase incoming line socket access port, and the outgoing line socket access port includes a three-phase outgoing line socket access port and an N-phase outgoing line socket access port. The three-phase incoming line socket access port, the N-phase incoming line socket access port, the three-phase outgoing line socket access port and the N-phase outgoing line socket access port are all provided with a quick access device, and a quick connection with the power supply vehicle and the low-voltage switch is achieved through a quick connection plug.

[0037] Specifically, the three-phase incoming socket access port and the N-phase incoming socket access port are respectively used to connect the three-phase power supply and neutral line of the power supply vehicle. This design can ensure that the phase of the power supply is connected correctly, thereby ensuring the normal operation of the power system; the three-phase outgoing socket access port and the N-phase outgoing socket access port are respectively used to connect to the three-phase power supply and neutral line of the low-voltage switch. This design also ensures the correct phase of the output power supply, which facilitates the access and use of downstream equipment.

[0038] The above four ports (three-phase incoming socket access port, N-phase incoming socket access port, three-phase outgoing socket access port and N-phase outgoing socket access port) are equipped with quick access devices, which usually refer to specially designed sockets and plugs, which can achieve quick connection and disconnection without complicated wiring operations; the quick connection plug is matched with the above-mentioned quick access device to achieve quick connection between the power supply vehicle and the low-voltage switch and branch box; the quick connection plug has the following advantages: only simple insertion and removal actions are required to complete the connection or disconnection; the design ensures the stability of the connection and reduces failures caused by poor connection; the quick connection plug usually has safety features such as anti-misinsertion and anti-falling, which reduces operational risks; in situations where the power supply needs to be frequently connected or disconnected, the quick connection plug can greatly improve work efficiency.

[0039] Through this design, the low-voltage bypass power generation quick access branch box of the embodiment of the present invention can be quickly put into use in emergency or temporary power supply situations, while ensuring the accuracy and safety of wiring.

[0040] Furthermore, the incoming line socket access port is linked to the micro switch group. When the external incoming line connector is inserted into the incoming line socket access port, the micro switch group is automatically started to light up or go out the three-phase incoming line power indicator light to directly reflect the corresponding wiring connection status and the opening and closing status of the circuit breaker.

[0041] Specifically, the incoming line socket access port is linked to the micro switch group: this means that when an external incoming line connector (for example, the power output plug of a power supply vehicle) is inserted into the incoming line socket access port, this action will trigger the micro switch group through some mechanical or electronic linkage device; a micro switch is a small switch that can open or close a circuit when subjected to slight physical contact or action; in the present invention, the micro switch group is used to control the lighting or extinguishing of the three-phase incoming line power indicator light; when the incoming line connector is inserted into the incoming line socket access port, the linkage mechanism will automatically start the micro switch group without the need for additional manual operation; this design improves operational convenience and reduces the possibility of human operational errors.

[0042] The three-phase incoming power indicator light is a visual indicator device on the branch box, which is used to display the power status of the three-phase incoming line; when the micro switch group is activated, the indicator light will light up or go out according to the state of the switch; when the three-phase incoming power indicator light is on, it means that the incoming line connector has been successfully inserted, the connection between the incoming line socket access port and the power supply vehicle is connected, and the circuit breaker is in the closed state, and the current can flow normally; when the three-phase incoming power indicator light is off, it may mean that the incoming line connector is not inserted or has been unplugged, or the circuit breaker has tripped due to overload or other reasons, cutting off the current.

[0043] Through the design of such linkage connection and indicator light, the embodiment of the present invention provides an intuitive feedback mechanism, so that the operator can quickly determine the connection status of the power supply and the opening and closing status of the circuit breaker, thereby improving the operational safety and maintenance efficiency of the power system.

[0044] Furthermore, the digital display is also used to store the values ​​of the working current and voltage, so as to facilitate the query and analysis of the power supply situation.

[0045] Specifically, the digital display meter of the present embodiment can display the current and voltage values ​​of the power system in real time, and provide the operator with instant power parameter information; the digital display meter of the present embodiment also has a storage function, and can record the current and voltage values ​​within a certain period of time, and these data can be used for subsequent query and analysis; the operator can query the historical recorded current and voltage data through the digital display meter to understand the operation status of the power system in the past period of time; by analyzing the stored data, the operator can identify the use pattern of the power system, potential problems or abnormal conditions, such as current fluctuations, voltage instability, etc.

[0046] By analyzing the stored data, the performance of the power system can be better monitored, potential problems can be discovered and resolved in a timely manner, thereby reducing failures and downtime; understanding power usage can help optimize power resource allocation, improve energy efficiency, and reduce operating costs; by analyzing current and voltage data, it can ensure that the power system operates within a safe parameter range to prevent overload and other potential safety risks; the stored data can provide decision support for management, such as when considering system upgrades or expansions, it can serve as an important reference. The above disclosure is only a preferred embodiment of the present invention, and of course it cannot be used to limit the scope of the rights of the present invention. Therefore, equivalent changes made in accordance with the claims of the present invention are still within the scope covered by the present invention.
