Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. The components of the embodiments of this utility model described and shown in the accompanying drawings can generally be arranged and designed in various different configurations.

[0017] like Figure 1 , Figure 2 As shown, this utility model provides one embodiment: a sulfur hexafluoride gas data monitoring system, comprising: a control module, a sensor network, a communication module, a power supply module, and a monitoring center; the sensor network is wirelessly connected to the control module via the communication module, the control module is wirelessly connected to the monitoring center via the communication module, and the power supply module is electrically connected to the control module; wherein, the power supply module comprises: a solar panel, a charging controller, a battery, a DC-DC converter, an AC power supply device, an AC-DC adapter, and a switching relay; the solar panel is electrically connected to the charging controller, the charging controller is electrically connected to the battery, the battery is electrically connected to the DC-DC converter, the AC power supply device is electrically connected to the AC-DC adapter, the DC-DC converter and the AC-DC adapter are respectively electrically connected to the switching relay, and the switching relay is electrically connected to the control module.

[0018] In this embodiment, a sensor network collects sulfur hexafluoride gas monitoring data, such as temperature, pressure, humidity, and gas concentration, and transmits it wirelessly to the control module. The communication module transmits the data collected by the sensor network to the control module. The control module receives the data from the sensor network and sends the processed data to the monitoring center via the communication module. The monitoring center receives the data from the control module and monitors the sulfur hexafluoride gas status in real time, enabling staff to promptly identify problems and take appropriate measures. The power module provides the system with the necessary power. Solar panels convert solar energy into electrical energy, which is stored in a battery, via a charge controller. A DC-DC converter converts the electrical energy into the DC power required by the system. A mains power supply and an AC-DC adapter serve as backup power. A switching relay switches to battery power in case of a mains power outage.

[0020] The sulfur hexafluoride (SF6) gas is mainly used as an insulating medium in the high-voltage switch equipment in the hydropower station. Monitoring the properties of SF6 gas is crucial to ensure the safety and efficiency of the operation of the equipment, therefore, the sulfur hexafluoride gas sensor is installed near the high-voltage switch equipment in this embodiment, to monitor the SF6 gas leakage in real time, and ensure that the gas concentration of sulfur hexafluoride is within a safe range. It can be understood that the safe range here can be a specific threshold value, which is set to 1000 ppm here, and in fact can be adjusted as needed, that is, the fixed value stored in the data storage as described below. When the concentration value exceeds this value, an alarm is triggered.

[0021] Further, the sensor network comprises: a gas pressure sensor fixedly installed in the pressure container of the sulfur hexafluoride gas device of the hydropower station, used for detecting the pressure change of the sulfur hexafluoride gas in the pressure container, and the gas pressure sensor is wirelessly connected to the control module through the communication module.

[0022] The SF6 gas storage container is used to store SF6 gas, so as to supply SF6 gas to the high-voltage switch equipment when needed, for insulation and operation, therefore, the gas pressure sensor is arranged on the pressure container of the SF6 gas device in this embodiment, to determine the SF6 gas pressure by measuring the difference from a known standard pressure, so as to monitor the pressure of the SF6 gas, and ensure that the gas pressure is within a safe range for the operation of the equipment. Similarly, the safe range here is the preset value as described above, which is set to 5 bar here.

[0023] Further, the sensor network comprises: a temperature sensor fixedly installed at the sulfur hexafluoride gas device and the high-voltage switch equipment of the hydropower station, used for detecting the ambient temperature of the sulfur hexafluoride gas device and the high-voltage switch equipment of the hydropower station, and the temperature sensor is wirelessly connected to the control module through the communication module.

[0024] Temperature changes can affect the pressure and insulation performance of SF6 gas, therefore, the temperature sensor is arranged at the sulfur hexafluoride gas device and the high-voltage switch equipment of the hydropower station in this embodiment, to monitor the temperature of the SF6 gas and its surrounding environment. Here, the preset value of the temperature is 60 degrees Celsius.

[0025] Further, the sensor network comprises a humidity sensor fixedly installed at the SF6 gas device and high-voltage switch equipment of the hydropower station, for detecting the ambient humidity of the SF6 gas device and high-voltage switch equipment of the hydropower station, and the humidity sensor is wirelessly connected to the control module through the communication module.

[0026] Since the insulation performance of SF6 gas will be reduced due to excessive humidity, it is important to monitor the ambient humidity, and the humidity sensor is arranged at the SF6 gas device and high-voltage switch equipment of the hydropower station to monitor the moisture content in the SF6 gas, and the preset humidity value is 80%.

[0027] In the embodiment, the monitoring center comprises a display module, specifically an LCD liquid crystal display screen, for displaying the data detected by the sensor network.

[0028] More specifically, the monitoring center further comprises an alarm module and a data storage, and the data storage is pre-stored with threshold values of the detection data of the sensor network, and the alarm module is used for alarming the detection data exceeding the threshold values.
