At the same time, an external environment analysis module and an electrical parameter analysis module are set in the remote control platform. The external environment analysis module and the electrical parameter analysis module are used to analyze the data detected by the information acquisition unit to determine whether there is an abnormality in the isolating switch. If it is determined that the isolating switch is abnormal, a control signal is generated to remotely control the isolating switch;

Finally, the feedback unit can monitor the duration of the intelligent controller executing the autonomous control signal and the control signal, as well as the opening and closing status of the isolating switch after the execution signal, and the monitoring results can be fed back to the remote monitoring platform, so that the staff can understand the control status of the isolating switch in time.

[0081] It should be noted that the communication unit includes 4G / 5G / NB-IOT / Zigbee, relying on the intelligent control system of the 220kV disconnector. The transmission network is selected according to the communication rate, communication distance, communication protocol, installation flexibility, work efficiency, economy and environmental requirements, making data transmission more flexible.

[0082] The information collection unit includes:

[0083] Electrical parameter acquisition module, used for:

[0084] Deploy corresponding monitoring equipment on the power supply line of the disconnector, detect the voltage and current of the power supply line through the deployed monitoring equipment, generate voltage data and current data, and finally obtain the electrical parameters of the power supply line;

[0085] Environmental information acquisition module, used for:

[0086] Corresponding monitoring equipment is deployed on the power supply line of the isolating switch. The temperature and humidity of the environment around the isolating switch are detected by the deployed monitoring equipment to generate temperature data and humidity data, and finally obtain environmental information about the isolating switch;

[0090] Voltage sensors for:

[0091] Automatically detect the voltage signal in the power supply line and generate voltage data;

[0092] Current sensors for:

[0093] Automatically detect current changes in the power supply line and generate current data;

[0095] Detect temperature changes around the disconnector in real time and generate temperature data;

[0096] Humidity sensors for:

[0097] Detect humidity changes in the environment around the disconnector in real time and generate humidity data.

[0098] The technical effect of the above content is: during the operation of the isolating switch, there are some common faults, such as: current and voltage problems in the power supply line of the isolating switch, and temperature and humidity problems in the environment around the isolating switch. When the above problems occur, it is easy to affect the normal operation of the isolating switch. The electrical parameter acquisition module deploys voltage sensors and current sensors on the power supply line to detect the voltage and current of the power supply line, thereby generating voltage data and current data, and then obtaining relevant electrical parameters of the power supply line. The environmental information acquisition module deploys temperature sensors and humidity sensors around the isolating switch, which can detect the temperature and humidity of the environment around the isolating switch, thereby generating temperature data and humidity data, and then obtaining environmental information around the isolating switch. By acquiring the above data, some common faults of the isolating switch can be analyzed to ensure safe and reliable operation of the power system.

[0099] Remote control platform, including:

[0100] Autonomous control module for:

[0101] Autonomously generate autonomous control signals to remotely control the disconnector;

[0102] External environment analysis module, used for:

[0103] Compare and analyze the temperature and humidity data with the preset thresholds to determine whether there are abnormalities in the temperature and humidity of the environment around the disconnector;

[0104] Among them, the temperature standard range of the isolating switch is 40℃-65℃;

[0105] The relative humidity of the disconnector is 50% to 90%;

[0106] Electrical parameter analysis module for:

[0107] Analyze the changes in voltage and current data to determine whether there are any abnormalities in the power supply line of the isolation switch;

[0108] Fault control module for:

[0109] According to the analysis results of the external environment analysis module and the electrical parameter analysis module, a control signal is generated to remotely control the isolating switch.

[0110] Fault warning module, used for:

[0111] When the fault control module generates a control signal, a warning notification is issued, and the analysis results of the external environment analysis module and the electrical parameter analysis module are displayed.

[0112] The fault control module specifically performs the following processes:

[0113] If the analysis result of the external environment analysis module determines that there is an abnormality in the isolating switch, a control signal is generated to control the isolating switch to open;

[0114] If the analysis result of the electrical parameter analysis module determines that the isolating switch is abnormal, a control signal is generated to control the isolating switch to open;

[0115] Wherein, if one or more of the analysis results are abnormal, a control signal is immediately generated;

[0116] When the abnormality of the isolating switch is resolved, a control signal is generated to control the isolating switch to perform a closing action.

[0117] The technical effect of the above content is: the remote control platform can autonomously control the isolating switch or control it according to the fault situation. When no fault is detected, the staff can autonomously generate autonomous control signals through the autonomous control module to control the opening and closing actions of the isolating switch, thereby realizing remote control of the isolating switch, or analyzing the detection data of the power supply line and the surrounding environment of the isolating switch obtained by the information acquisition unit, and comparing and analyzing the temperature data and humidity data with the pre-set thresholds through the external environment analysis module to analyze whether the temperature and humidity exceed the standard range. If the temperature and humidity do not exceed the standard range, it is judged that the surrounding environment of the isolating switch is normal. If one or all of the temperature and humidity exceed the standard range, it is judged that the temperature and humidity of the surrounding environment of the isolating switch are abnormal. The electrical parameter analysis module can analyze the changes in voltage data and current data to analyze whether the voltage and current meet the power supply line standards. If the voltage and current meet the standards, then It is determined that the voltage and current of the power supply line of the isolating switch are normal. If one or all of the voltage and current do not meet the standards, it is determined that the voltage and current of the power supply line are abnormal. According to the above analysis results, when there is an abnormal situation, a control signal is generated by the fault control module and transmitted to the intelligent controller by the communication unit, so that the intelligent controller controls the opening action of the isolating switch according to the autonomous control signal and the control signal. It should be noted that when the isolating switch is analyzed to be abnormal and the control signal is generated by the fault control module, an early warning notification will be issued through the fault early warning module to remind the staff to pay attention to the failure of the isolating switch, so as to take relevant measures to solve the failure of the isolating switch in time. After the fault is eliminated, a control signal is generated to control the isolating switch to close the switch. Through the above process, the isolating switch can be remotely controlled, and the possible faults can be predicted by real-time detection of the isolating switch, so as to control the isolating switch in time to avoid power accidents.

[0118] Feedback unit, comprising:

[0119] Control execution feedback module, used to:

[0120] Monitor in real time the duration of the intelligent controller executing the autonomous control signal and the control signal, determine whether the intelligent actuator executes the autonomous control signal and the control signal in a timely manner according to the monitored execution duration, and feed back the monitoring results to the remote control platform through the communication unit;

[0121] Switch status feedback module for:

[0122] After the intelligent controller executes the autonomous control signal and the control signal, the opening and closing status of the disconnector is monitored in real time. Through monitoring, it is determined whether the disconnector correctly executes the opening and closing actions of the autonomous control signal and the control signal, and the monitoring results are fed back to the remote control platform through the communication unit.

[0123] The technical effect of the above content is: the feedback unit can feedback the execution effect of the isolating switch to the remote control platform by controlling the execution feedback module and the switch status feedback module. The execution feedback module can monitor the duration of the intelligent controller executing the autonomous control signal and the control signal, so as to determine whether the intelligent controller has timed out the control. At the same time, the switch status feedback module can monitor the opening and closing status of the isolating switch, so as to determine whether the isolating switch performs the corresponding opening and closing actions according to the autonomous control signal and the control signal. The above monitoring results will be fed back to the remote monitoring platform so that the staff can understand the control status of the isolating switch in a timely manner.

[0124] Control execution feedback module, including:

[0125] Feedback information receiving module, used for:

[0126] The intelligent controller generates known feedback information after receiving the autonomous control signal and the control signal, and stops sending the autonomous control signal and the control signal;

[0127] Monitoring duration module, used for:

[0128] Monitor the duration of generating known feedback information, where the monitoring duration ranges from 0min to 5min.

[0129] The switch status feedback module specifically performs the following process:

[0130] Deploy electrical parameter detection instruments on the disconnector;

[0131] Measure the electrical parameters of the disconnect switch through the deployed electrical parameter detection instruments;

[0132] Compare the measured electrical parameters with the standard values ​​when the disconnector is closed;

[0133] If the electrical parameters meet the standards, the isolating switch is in the closed state, otherwise, the isolating switch is in the open state.

[0134] The technical effect of the above content is: after the intelligent controller receives the autonomous control signal and the control signal, the feedback information receiving module will generate known feedback information. The known feedback information is used to indicate that the intelligent controller has received the autonomous control signal and the control signal and made corresponding control. The control execution feedback module stops sending the autonomous control signal and the control signal to the intelligent controller after receiving the known feedback information. The generation time of the known feedback information can be detected by the monitoring time module. If the monitoring time exceeds 0min-5min, it means that the intelligent controller has failed to execute the corresponding control in time, and it is necessary to immediately feedback to the remote control platform to ensure timely control of the isolating switch. Control is performed to improve the reliability and responsiveness of the system, and the switch status feedback module measures the electrical parameters of the disconnector through the deployed electrical parameter detection instrument, and compares the measured electrical parameters with the standard values ​​when the disconnector is closed to determine whether the detected electrical parameters meet the standards. If so, the disconnector is in the closed state, otherwise, the disconnector is in the open state. In this way, the status of the disconnector can be monitored, and the monitoring results will also be fed back to the remote control platform so that the staff can promptly understand whether the disconnector performs the corresponding opening and closing actions according to the autonomous control signal and the control signal, thereby further improving the reliability and responsiveness of the system.

[0135] Working principle: The remote control platform can control the isolating switch autonomously or according to the fault situation. When no fault is detected, the staff can autonomously generate autonomous control signals through the autonomous control module to control the opening and closing actions of the isolating switch, or analyze the detection data of the power supply line and the surrounding environment of the isolating switch obtained by the information acquisition unit to determine whether there is an abnormality in the isolating switch. When the isolating switch is judged to be abnormal, a control signal is generated to remotely control the isolating switch. Through the above process, the isolating switch can be remotely controlled, and the isolating switch can be detected in real time, and possible faults can be predicted so as to be timely Control the isolating switch to avoid power accidents. The feedback unit can feedback the execution effect of the isolating switch to the remote control platform through the control execution feedback module and the switch status feedback module. The execution feedback module can monitor the duration of the intelligent controller executing the autonomous control signal and the control signal, so as to determine whether the intelligent controller has timed out. At the same time, the switch status feedback module can monitor the opening and closing status of the isolating switch, so as to determine whether the isolating switch executes the corresponding opening and closing actions according to the autonomous control signal and the control signal. The above monitoring results will be fed back to the remote monitoring platform so that the staff can understand the control status of the isolating switch in time.
