Description

Technical Field

[0001] This invention belongs to the field of high-voltage equipment line switching technology, specifically relating to an intelligent distribution cabinet. Background Technology

[0002] When providing power, reliability and safety are key considerations.

[0003] In certain specific situations, high-voltage equipment requires switching between two control modes or, in order to ensure the normal operation of the equipment, a redundant control mode is required. Therefore, this invention provides an intelligent distribution cabinet to economically and reliably achieve backup and switching of its control power supply. Summary of the Invention

[0004] In view of the shortcomings of existing technologies, the purpose of this invention is to provide an intelligent distribution cabinet that adopts an integrated cabinet design, reduces the construction period, and meets the requirements of high-voltage equipment that needs to switch between two control modes or have redundant control.

[0005] To achieve the above-mentioned technical objectives, the technical solution adopted by the present invention is as follows: A smart distribution cabinet includes internally installed... Busbar, connected to the power input terminal. The first load switch is located on the main line and determines the on / off state of the main line, which connects the electrical load end and the bus outlet end. The second load switch is located on the standby line and determines the on / off state of the standby line, which connects the electrical load end and the bus outlet end. The RTU unit is used to control the status of the first load switch and the second load switch.

[0006] The core idea of ​​this invention is one incoming line and two outgoing lines. One incoming line is connected to the power input terminal, and the two outgoing lines are connected to the electrical load terminal, thereby realizing the division of one high-voltage incoming line into two incoming lines. Among them, one incoming line refers to the incoming line of the power supply formed by connecting the busbar and the power input terminal; Two outgoing lines refer to the main line and the backup line supplying power to the high-voltage equipment that serves as the electrical load. When a fault occurs on the main line, the RTU unit communicates with the remote control system to report the fault information. The remote control system receives the signal, analyzes and judges it, and then automatically disconnects the first load switch on the main line and closes the second load switch on the backup line through the RTU unit, thereby realizing intelligent switching of power lines and achieving the branch line function.

[0007] In some optional instances, the first load switch and the second load switch are not simultaneously closed, thus avoiding the simultaneous connection of the main line and the backup line.

[0008] In some optional examples, the cabinet includes a cabinet body and a cabinet door. When the cabinet door is in the open state, both the first load switch and the second load switch are in the off state, thus preventing safety accidents when the cabinet door is open and improving safety.

[0009] In some optional examples, the cabinet is provided with a low-voltage chamber, a busbar chamber, and a cable chamber, and the cabinet door is provided with an observation window for observing the cable chamber; the RTU unit is located in the low-voltage chamber, and the first load switch, the second load switch, and the busbar are all located in the busbar chamber; the cable chamber is provided with inlet terminals and outlet terminals. In this way, functional zoning is achieved through different chambers, the observation window is used to observe the cable chamber without opening the cabinet door, and the inlet and outlet terminals facilitate cable entry and exit wiring.

[0010] In some optional instances, a display controller is also included to display various information and provide a medium for inputting manual control information, ensuring the operation of the first load switch and the second load switch under special circumstances.

[0011] In some optional instances, indicator lights are also included to indicate whether the primary and backup lines are operational. These indicator lights convey the working status of the primary and backup lines to staff visually through light signals.

[0012] In some optional instances, the intelligent distribution cabinet itself is powered by a DC system or UPS power supply, which is provided externally to ensure the safe and stable operation of the intelligent distribution cabinet.

[0013] The beneficial effects of this invention are: 1. Meet the requirements of high-voltage equipment that necessitates switching between two control modes or has redundant control; 2. It enables remote automatic switching, reducing the potential dangers associated with manual switching; 3. It adopts a cabinet design, which takes up little floor space. Attached Figure Description

[0016] like Figure 1 , 2 As shown in Figure 3, this embodiment provides an intelligent distribution cabinet, including a cabinet body 1 and a cabinet door 7, and a [missing information - likely a device or component] disposed inside the cabinet body 1. Busbar, connected to the power input terminal. The first load switch 4 is located on the main line 2 and determines the on / off state of the main line 2. The main line 2 connects the electrical load end and the bus outlet end. The second load switch 5 is located on the standby line 3 and determines the on / off state of the standby line 3. The standby line 3 connects the electrical load end and the bus outlet end. RTU unit 6 is used to control the status of the first load switch 4 and the second load switch 5; The first load switch 4 and the second load switch 5 are not in the closed state at the same time; When cabinet door 7 is open, both the first load switch 4 and the second load switch 5 are in the off state.

[0017] In this embodiment, the busbar is connected to the power input terminal, allowing electrical energy to enter the interior. The first load switch 4 and the second load switch 5 selectively determine whether the path of the electrical energy is the main line 2 or the backup line 3. The main line 2 and the backup line 3 output power to the high-voltage equipment that serves as the electrical load terminal. When a fault occurs on one side of the main line 2, the RTU unit 6 communicates with the remote control system and reports the fault information. The remote control system receives the signal and, after analysis and judgment, automatically disconnects the first load switch 4 on the main line 2 and closes the second load switch 5 on the backup line 3 through the RTU unit 6, thereby realizing intelligent switching of power lines and achieving the line splitting function. The first load switch 4 and the second load switch 5 are not in the closed state at the same time to avoid the main line 2 and the backup line 3 being connected at the same time. When the cabinet door 7 is opened, the first load switch 4 and the second load switch 5 cannot be closed, which can ensure safe use. This invention meets the requirements of high-voltage equipment that needs to switch between two control modes or has redundant control; it can realize remote automatic switching, reducing the dangers that may be caused by manual switching; and it adopts the cabinet type, which has a small footprint.
