[0045] In order to make the purpose, technical scheme and advantages of the utility model more clear, the following examples further detail the utility model. The pronouns and pronouns about people in the patent application are not limited to specific gender.

[0046] The switch cabinet is an important component device in the power system, and mainly functions to open and close, control and protect the electrical equipment in the process of power generation, power transmission, power distribution and power conversion in the power system. At present, the intelligent demand of the switch cabinet is more and more popular, and it is necessary to set an acquisition device in the switch cabinet. The acquisition device can be used to collect data of the switch cabinet, such as temperature, humidity, voltage and current of the switch cabinet. The acquisition device can also be used to receive control information to control other components, such as temperature, humidity, voltage or current in the switch cabinet.

[0047] For the convenience of description, the switch cabinet provided with the "gateway device" is referred to as "switch cabinet" below.

[0048] As shown in Figure 1 The structure of the switch cabinet according to the utility model. The switch cabinet will be divided into four independent compartments by the partition, which are busbar room 1, cable room 2, handcart room 3 and low-voltage room 4. The acquisition device (not shown in the figure) is used to collect data of the switch cabinet, and the communication protocols of at least two acquisition devices are different. The switch cabinet also includes a gateway device 5 located in the low-voltage room 4, and the gateway device 5 is used to obtain data of each acquisition device. The gateway is also used to communicate with the external control system to send the obtained data to the control system and receive the control information of the control system to send to the corresponding control device.

[0049] The collection device described above can be located in the same switch cabinet as the gateway device 5, or can be located in a different switch cabinet from the gateway device 5. For example, part of the plurality of collection devices are located in the same switch cabinet as the gateway device 5, and the other part of the collection devices are distributed in other switch cabinets, or all of the plurality of collection devices are located in the same switch cabinet as the gateway device 5, which is not limited herein, and the collection device collects data of the switch cabinet. For the same type of collection device, it can communicate with the gateway device 5 in a wireless communication manner, or it can communicate with the gateway device 5 in a wired communication manner. In the case of using a wired communication manner, the same type of collection device can be connected together first and then connected to the gateway device 5, for example, the temperature and humidity controllers in different switch cabinets can be connected to the same communication bus, and then connected to the gateway device 5 through the communication bus, or the collection devices using the same communication protocol can be connected to the same communication bus first and then connected to the gateway device 5. In this way, the gateway device 5 can set fewer physical interfaces to communicate with multiple collection devices or control devices, which is beneficial to the miniaturization of the gateway device 5.

[0050] Each collection device can include at least one of the following devices: an angular velocity sensor, a temperature and humidity controller, a lightning arrester monitor, a wireless temperature sensor, and an environmental temperature and humidity sensor. Of course, it can also be other collection devices capable of communication, which is not limited herein. Accordingly, the data of the switch cabinet herein includes operating data of the switch cabinet, environmental data, etc. Each collection device can include multiple devices of the same type or multiple devices of different types, which is not limited herein. The gateway device 5 can communicate with each collection device to obtain the data of the switch cabinet obtained by each collection device. The gateway device 5 can communicate with each collection device using different communication protocols, for example, the gateway device 5 has multiple communication interfaces and can communicate in a wired manner through different communication protocols. The gateway device 5 can communicate with the collection device, the control system or the control device in a wireless communication manner using different communication protocols. The gateway device 5 can also communicate with the control system, which is equivalent to a relay station for sending the obtained data to the control system. The control system sends a control command to the control device according to the received data. The control command can also be transmitted through the gateway device 5. The control device and the collection device can be the same device, for example, a temperature and humidity controller, which can collect data of the operating environment of the switch cabinet and trigger the corresponding heater or humidifier to work. Of course, the control device and the collection device can be different devices, which is not limited herein. The control device can be arranged in the switch cabinet.

[0051] The control system or the control device herein can also be of different communication protocols, and the gateway device 5 can communicate with these control systems or control devices.

[0052] The gateway device 5 is, for example, an IOT2050 device, which can not only apply MODBUS RTU, MODBUS TCP, IEC61850, OPC UA Pub / sub and other local communications, but also support various local MODBUS intelligent devices, and can be connected to a cloud-deployed platform. Of course, the gateway device 5 can also be other types of devices, as long as it has the corresponding communication functions described above, and details are not repeated here. How the gateway device 5 communicates with the collection device, the control system or the control device is a prior art, and details are not repeated here.

[0053] The aforementioned remote control system is, for example, a cloud platform application or a local application, for example, a local or cloud platform mobile APP and web application, an energy management system or a resource management system, etc. The remote control system can be used to query corresponding data and issue corresponding control commands.

[0054] In addition, the gateway device 5 can also be configured with an HMI (Human Machine Interface), so that the user can configure the gateway device 5 according to the human-machine interface, for example, input the identification number of the collection device to inform the gateway device 5 which data of the collection device needs to be collected. How to configure it is a prior art, and details are not repeated here.

[0055] According to the switch cabinet of the utility model, through setting gateway device 5 in it, and the gateway device 5 can communicate with the collection device of different protocol, like this, can give user's great choice space. The gateway device 5 is arranged in the low-voltage chamber 4, not only convenient for the installation of gateway device 5, and will not cause the influence to other chamber parts.

[0056] As an example, as shown in Figure 2 and Figure 3 The gateway device 5 includes a device body 51 and a wireless communicator 52. The device body 51 has a USB interface 511, and the wireless communicator 52 can be inserted into the USB interface 511. Such a connection method is simple and fast, and the split setting mode is conducive to the installation of the gateway device 5 in the switch cabinet. The device body 51 includes a shell and internal components such as various communication boards, and the wireless communicator 52 is used to communicate with external devices wirelessly. Figure 2The diagram shows two USB ports 511, which can be further configured according to actual needs. As another example, the gateway device 5 also includes an antenna 53, which can be connected to the end of the wireless communicator 52 furthest from the USB ports 511. The antenna 53 enhances the power of the wireless communicator 52, enabling data acquisition devices, control systems, or control devices located far from the gateway device 5 to communicate with it, thus improving communication stability and reliability. This split-type gateway device 5 allows users to choose whether or not to install the antenna 53 based on their actual needs.

[0057] As an example, in addition to the USB interface 511, the device body 51 also includes at least one of the following interfaces:

[0058] Video interface 512;

[0059] Ethernet interface 513;

[0060] COM interface (serial communication interface) 514.

[0061] like Figure 2 As shown, these interfaces can all be located on one side of the device body 51 for easy cable routing. Figure 2 The diagram shows two Ethernet interfaces 513, two USB interfaces 511, one video interface 512, and one COM interface 514. The Ethernet interface 513 is used to connect a network cable, the video interface 512 is used to connect an external display device, such as an HMI (not shown in the diagram), and the COM interface 514 is connected to a data acquisition device that communicates via a serial communication protocol. Figure 2 The diagram also shows a power interface 515 for connecting an external power module 8 to provide power to the gateway device 5.

[0062] like Figure 3As shown, in addition to the gateway device 5, the low-voltage chamber 4 also includes a miniature circuit breaker 6, an electric controller 7, a power module 8 and a terminal groove 9. The gateway device 5, the miniature circuit breaker 6, the electric controller 7 and the power module 8 are arranged side by side in sequence, and the terminal groove 9 is located below the gateway device 5, the miniature circuit breaker 6, the electric controller 7 and the power module 8. Of course, the terminal groove 9 can also be located at the side of the gateway device 5, the miniature circuit breaker 6, the electric controller 7 and the power module 8, and the specific arrangement can be selected according to actual needs, which is not limited herein. The miniature circuit breaker 6 is used to control the electrical circuit, and there can be multiple miniature circuit breakers 6. The electric controller 7 is used to control the electrically-driven in-out of the handcart chamber 3 or to control the electrically-driven opening or closing of the grounding switch of the cable chamber. The terminal groove 9 is used to connect the wiring of the control components in the switch cabinet. The power module 8 can supply power to the gateway device 5 or other components. For example, the power module 8 is a DC 24V power supply. Figure 3 As can be seen, the interface of the gateway device 5 is upward, i.e., away from the side of the terminal groove 9. The gateway device 5 is attached to the terminal groove 9 to leave a corresponding installation space for the wireless communicator 52 and the antenna 53. Due to the limited space of the low-voltage chamber 4, such an arrangement enables the gateway device 5 to be placed in the low-voltage chamber 4.

[0063] The handcart chamber 3 of the switch cabinet includes a circuit breaker and an aviation plug, which can connect components on the electrical circuit of the circuit breaker to communicate with other components. The circuit breaker has an operating shaft that can rotate with the movable contact on the circuit breaker to close or open the circuit. As an example, the collection device is an angular velocity sensor fixed to the operating shaft. The angular velocity sensor is connected to the aviation plug and transmits data to the gateway device 5 through the aviation plug. In this way, the control system can obtain the angle of rotation of the operating shaft and further analyze the position of the circuit breaker, etc.

[0064] As an example, the collection device can be a temperature and humidity controller, which can be arranged on the door of the low-voltage chamber 4. The temperature and humidity controller is used to detect the working environment of the switch cabinet, such as temperature and humidity, and trigger corresponding components to adjust the working environment of the switch cabinet according to the detection results. The gateway device 5 can obtain real-time data of the temperature and humidity controller and send it to the control system.

[0065] As another example, the collection device can be a lightning arrester monitor, which is connected in series with the lightning arrester in the cable chamber 2. The lightning arrester monitor is used to monitor the working state of the lightning arrester, such as monitoring the current or voltage of the lightning arrester, and recording the number of times and leakage current of the lightning arrester. The gateway device 5 can obtain real-time data of the lightning arrester monitor and send it to the control system for analysis.

[0066] As a further example, the collection device can be a wireless temperature sensor or an environmental temperature and humidity sensor. The wireless temperature sensor can be arranged at a position where temperature needs to be monitored, for example, at a copper bar joint. Correspondingly, the environmental temperature and humidity sensor can also be arranged at a position where temperature and humidity needs to be monitored. The details are not described herein. The gateway device 5 can acquire the data and send it to the control system for analysis.

[0067] If a plurality of collection devices include a plurality of target devices of the same type that communicate using a physical bus, such as temperature and humidity controllers or arrester monitoring devices, the target devices can be connected, and the connected bus can be connected to the port corresponding to the physical bus of the gateway device 5. Here, the physical bus means that the target device is connected to the gateway device 5 by wire. In this way, the number of interfaces of the gateway device 5 is reduced, which facilitates the miniaturization of the gateway device 5 and facilitates placement in the switch cabinet.

[0068] The utility model also provides a switchgear group cabinet, the switchgear group cabinet includes the switchgear of any preceding embodiment and a plurality of other switchgears, at least one other switchgear includes collection device, gateway device 5 can receive the data of collection device in each other switchgear. The type of other switchgears here can be the same as the aforementioned switchgear, or it can be a switchgear of a different type. In practical applications, multiple switchgears are usually used in combination. For the sake of convenience in description, the switchgears that are not provided with gateway devices 5 are referred to as "other switchgears", and the switchgears are usually arranged side by side, and the two adjacent switchgears are connected by conductors. In this way, for a switchgear group cabinet, only one switchgear provided with a gateway device 5 is needed to achieve the acquisition of the data of the collection devices of each switchgear, such as through wireless transmission or through wired transmission. For wired transmission, the collection devices using the same communication protocol can be connected together and then connected to the gateway device 5, or the gateway device 5 can be connected through a switch, which is not limited.

[0069] The switchgears and the other switchgears are arranged side by side, and the switchgear is located at the middle position of the plurality of other switchgears. For example, if the number of other switchgears is even, the switchgear is located at the middle position, and if the number of other switchgears is odd, the switchgear can be located at the adjacent position of the middle other switchgear. Such an arrangement facilitates the gateway device 5 to acquire the data of the collection devices in the other switchgears.

[0070] The above is only a preferred embodiment of the utility model, and is not used to limit the utility model. Any modification, equivalent replacement, improvement, etc. made within the spirit and principles of the utility model shall be included in the protection scope of the utility model.
