[0031] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of this application.
[0032] Figure 1This is a schematic diagram of a first grounding device according to an embodiment of this application.
[0033] The mobile overhead contact line intelligent grounding system provided in this embodiment includes at least one grounding device, which, for ease of description, is referred to here as the first grounding device. This mobile overhead contact line intelligent grounding system is used to effectively ground the overhead contact line to ensure the personal safety of operators performing maintenance on the overhead contact line. Figure 1 As shown, the first grounding device 10 includes a grounding switch 11, an observation window 12, a control room 13, and an interface room 14.
[0034] The interface compartment is equipped with a grounding terminal and an input terminal. The grounding terminal is connected to the earth via a ground wire and is also connected to the input terminal. The input terminal is also connected to one end of a grounding switch. One end of the ground wire is connected to the grounding terminal, and the other end is connected to the earth. The specific grounding method can be implemented according to national standards, and this application does not require it.
[0035] The other end of the grounding switch is connected to the contact network via a connecting wire. This grounding switch can receive control signals from the operator, namely grounding control signals and disconnection control signals. When a grounding control signal is received, the grounding switch closes, ensuring proper grounding of the contact network. When a disconnection control signal is received, the grounding switch opens, effectively cutting off the connection between the contact network and the earth, allowing it to operate normally.
[0036] The control room is equipped with multiple control modules, which are mechanically or signal-connected to the grounding switch to control the grounding switch's on or off state.
[0037] The automatic operation module is connected to the remote control system and is used to receive grounding or disconnection commands from the remote control system. Based on the grounding command, it outputs a grounding control signal or a disconnection control signal to the grounding switch. The grounding control signal is used to control the grounding switch to close, and the disconnection control signal is used to control the grounding switch to close.
[0038] The manual operation module generates grounding or disconnection control signals based on user actions. A control button connected to the grounding switch sends grounding or disconnection control signals to the grounding switch. Additionally, the manual operation module includes a manual operation handle connected to the actuating component of the grounding switch, used to close or open the grounding switch based on operator actions.
[0039] Furthermore, multiple control modules also include interlocking modules, which are linked to the automatic operation module and the manual operation module respectively, to achieve interlocking control between the automatic and manual control modules. These interlocking modules ensure that the grounding device is not disconnected when one side is controlling it to ground, thus preventing electric shock accidents caused by human error.
[0040] The control room is also equipped with multiple detection elements, each connected to a corresponding display component. These elements detect one or more operating parameters of the first grounding device and transmit these parameters to the display component for display. The multiple detection elements include some or all of a voltage transformer, current transformer, temperature sensor, humidity sensor, and barometric pressure sensor.
[0041] Multiple display components are arranged behind the observation window. Each display component is used to display at least one operating parameter of the first grounding device, so that the operator can observe and record the operating parameters based on the observation window and understand the operating status of the first grounding device. The operating parameters are voltage, current, temperature, humidity, or air pressure values.
[0042] As can be seen from the above technical solution, this embodiment provides a mobile contact network intelligent grounding system for grounding the contact network based on operator control. The system includes a first grounding device, which comprises a grounding switch, an observation window, a control room, and an interface room. The interface room has a grounding terminal and an input terminal. The grounding terminal is connected to the earth via a ground wire and is also connected to the input terminal, which is connected to one end of the grounding switch. The other end of the grounding switch is connected to the contact network via a connecting wire. Upon receiving a control signal from the operator, the grounding switch closes or opens, thus connecting or disconnecting the contact network from the grounding terminal. The control room has multiple control modules for controlling the connection or disconnection of the grounding switch. Multiple display components are located behind the observation window to display the operating parameters of the first grounding device. This system allows operators to ground the contact network without manual wiring, reducing their workload and improving work efficiency.
[0043] In another specific embodiment of this application, the mobile contact network intelligent grounding system further includes a remote control system 20 and one or more second grounding devices 30. The composition, structure, and function of the second grounding device are the same as those of the first grounding device; the descriptions of the first and second are for simplistic purposes only and do not imply any substantial difference between them.
[0044] The remote control system is connected to the first grounding device and the second grounding device respectively, and is used to send the control signal to the first grounding device and / or the second grounding device. The remote control system includes a host computer 21 and a remote control device 22 connected to the host computer. The remote control device is used to connect to the first grounding device and the second grounding device respectively, and is used to send the control signal to the corresponding first grounding device or the corresponding second grounding device, so that the grounding device that needs to be grounded performs a grounding action.
[0045] The remote control system enables remote operators to operate and monitor multiple grounding devices, thereby better avoiding human error and further improving safety.
[0046] The various embodiments in this specification are described in a progressive manner, with each embodiment focusing on the differences from other embodiments. The same or similar parts between the various embodiments can be referred to each other.
