[0002] The distribution room undertakes the important task of transmitting and distributing electric energy in the distribution network, and is an important component connecting the distribution network and users. The stable and reliable operation of the distribution room not only directly affects the operational reliability of the distribution network, but also affects the quality of electricity consumption of users. With the in-depth development of the construction of smart distribution networks, higher requirements are also put forward for the operational reliability and information level of distribution rooms. However, the current level of operation and maintenance management of distribution rooms is relatively low. Therefore, it is necessary to introduce intelligent monitoring systems based on emerging technologies such as the Internet of Things (IoT), big data, and machine learning in distribution rooms to achieve real-time monitoring of the distribution room environment and equipment operating status, deeply explore the value of various monitoring data, reduce the operation and maintenance costs of distribution rooms, and improve the management level of distribution rooms, so as to better cooperate with the construction of smart grids.

[0003] At present, the main problems in the operation and maintenance management of distribution rooms are:

[0004] (1) The environmental monitoring level and monitoring range of the power distribution room are insufficient, making it impossible to conduct effective fault location analysis;

[0005] (2) Inspection of power distribution rooms mainly relies on regular manual inspections, which not only has low work efficiency but also makes it difficult to find problems in a timely manner, and there are blind spots in inspections;

[0006] (3) The distribution rooms are widely distributed and contain a large number of electrical equipment, which poses risks such as electric shock and SF6 poisoning, and it is impossible to issue warnings when there is a threat to personal safety;

[0007] (4) The number of devices in the power distribution room is increasing, and their functions are becoming increasingly complex. The requirements for the number and skills of inspection personnel are getting higher and higher, resulting in increasing labor costs;

[0008] (5) There is a lack of real-time and effective monitoring of equipment status and support for online visualization data, making remote operation impossible and making it difficult to improve the level of automation. Utility Model Content

[0028] In order to make the technical problems to be solved, technical solutions and advantages of the present invention more clear, a detailed description will be given below in conjunction with the accompanying drawings and specific embodiments.

[0029] like Figure 1 As shown, the embodiment of the utility model provides a power distribution room operation and maintenance system based on the Internet of Things, including a power monitoring host 1, an environment monitoring host 2, a security monitoring host 3, a switch 4, a server 5, a monitoring large screen 6, and a mobile monitoring terminal 8. The power monitoring host 1, the environment monitoring host 2, and the security monitoring host 3 are connected to the server 5 through the switch 4, and the server 5 is connected to the monitoring large screen 6 and the mobile monitoring terminal 8;

[0030] like Figure 2As shown, the power monitoring host 1 is connected to the first UPS power supply 11, the temperature sensor 12, the voltage / current detection device 13, the power quality analyzer 14, the power monitoring meter 15, the reactive power compensation device 16, the overcurrent protection device 17, the switch cabinet control device 18, and the microcomputer protection device 19 in communication, and the first UPS power supply 11 is electrically connected to the external power 7;

[0031] like Figure 3 As shown, the environment monitoring host 2 is in communication connection with the second UPS power supply 21, the gas sensor 22, the temperature and humidity sensor 23, the water immersion sensor 24, the fire sensor 25, the fan 26, the air conditioner 27, the water pump 28, and the dehumidifier 29, and the second UPS power supply 21 is electrically connected to the external power 7;

[0032] like Figure 4 As shown, the security monitoring host 3 is communicatively connected to the third UPS power supply 31, the infrared sensor 32, the network high-definition ball camera 33, the network high-definition gun camera 34, the access control controller 35, the positioning module 36, the voice alarm module 37, and the wireless communication module 38, and the third UPS power supply 31 is electrically connected to the external power 7.

[0033] The voltage / current detection device 13 is a voltage transmitter and a current transmitter, which is used to collect the voltage and current of the power equipment in the power distribution room and transmit them to the power monitoring host 1.

[0034] The model of power monitoring instrument 15 is ACR120EL. ACR120EL multi-function network instrument is designed for power monitoring needs of power systems, industrial and mining enterprises, public facilities, and intelligent buildings. It can measure all common power parameters, such as three-phase current, voltage, active and reactive power, electricity, harmonics, etc.

[0035] The reactive power compensation device 16 is of model HZS-BKTBB. The HZS-BKTBB high-voltage indoor frame reactive power compensation device is mainly used for capacitive reactive power compensation and inductive reactive power compensation in the power frequency 10kV (6kV) power system, to adjust and balance the grid voltage, improve the power factor, reduce line loss, improve the quality of electric energy, and give full play to the production efficiency of power generation and power supply equipment.

[0036] The overcurrent protection device 17 is an overvoltage and overcurrent protector. An overcurrent and overvoltage protector is a device that monitors the current and voltage in a circuit by detecting the magnitude of the voltage and current in the circuit. When the current or voltage value exceeds a certain specified range, the circuit components and lines are protected by cutting off the circuit. In the power system, for the safety and stability of the system, it is necessary to protect the electric energy parameters such as current, voltage, and frequency. Traditional relay protection devices have the disadvantages of low accuracy, poor stability and reliability, troublesome setting, and cumbersome installation. Overcurrent and overvoltage protectors, with their great advantages of high integration, high stability, high reliability and high cost performance, have a wide influence and market share in the technical fields of generator, transformer, line protection, etc. The main features are: 1. High precision, stability and good reliability; 2. Centralized control, simple wiring and easy installation; 3. Replace the traditional multiple relay protection mode; 4. With overcurrent, overvoltage and undervoltage protection functions; 5. The protection of current adopts inverse time control; 6. All parameters are password protected to prevent arbitrary modification; 7. Fault indicator light, buzzer alarm, digital display of three-dimensional fault judgment.

[0037] The gas sensor 22 is a SF6+O2 sulfur hexafluoride oxygen dual gas sensor, which is used to monitor the gas conditions in the distribution room. For example, SF6 gas leakage detection sensors are installed in outdoor cable trenches, 35kV box-type distribution devices, 10kV box-type distribution devices, secondary equipment rooms and other areas, and interfaces are set to transmit SF6 gas leakage warning information. When the concentration of SF6 gas exceeds 1000ppm (the upper and lower limits can be set as needed), the system will display information about excessive concentration and issue an alarm. When the oxygen concentration is lower than 18% (the upper and lower limits can be set by yourself), the screen will display a warning message that the concentration is too low and an alarm will be issued.

[0038] The fire sensor 25 includes any one of a smoke sensor, a flame sensor, and a thermistor sensor or a combination thereof, and is used to monitor whether a fire occurs in the power distribution room.

[0039] The wireless communication module 38 is a 5G communication module, which is used to send the monitored security information to the remote monitoring terminal.

[0040] The working principle of the utility model is:

[0041] like Figure 1The utility model shown includes three subsystems: power monitoring, environment monitoring, and security monitoring. The power monitoring host 1, environment monitoring host 2, and security monitoring host are respectively the core. The monitored data is sent to the server through the switch to realize monitoring, and finally the data is displayed on the monitoring screen and the mobile monitoring terminal (such as a mobile phone). At the same time, when necessary, the relevant equipment of the three subsystems of power monitoring, environment monitoring, and security monitoring can be controlled by the mobile monitoring terminal to realize the necessary functions.

[0042] like Figure 2 As shown, the power monitoring subsystem includes a power monitoring host 1 and a first UPS power supply 11 electrically connected thereto, a temperature sensor 12, a voltage / current detection device 13, a power quality analyzer 14, a power monitoring meter 15, a reactive power compensation device 16, an overcurrent protection device 17, a switch cabinet control device 18, and a microcomputer protection device 19 in communication connection. Among them, the temperature sensor is arranged on the power line and important equipment nodes, such as the temperature monitoring of the connection points that are prone to overheating such as the disconnector contacts, the moving and static contacts, the busbar joints, the cable joints and the three-phase windings of the transformer. If the temperature is found to be too high, an early warning can be issued in time. The voltage / current detection device realizes the detection of AC and DC voltage and current, and the power quality analyzer 14, the power monitoring meter 15, the reactive power compensation device 16, the overcurrent protection device 17, the switch cabinet control device 18, and the microcomputer protection device 19 respectively realize their corresponding power monitoring functions, which will not be repeated here.

[0043] like Figure 3 As shown, SF6 gas leakage detection sensors are installed in outdoor cable trenches, 35kV box-type power distribution devices, 10kV box-type power distribution devices, secondary equipment rooms and other areas, and interfaces are set to transmit SF6 gas leakage warning information. When the concentration of SF6 gas exceeds 1000ppm (the upper and lower limits can be set as needed), the system will display the information that the concentration exceeds the standard and issue an alarm. When the oxygen concentration is lower than 18% (the upper and lower limits can be set by yourself), the screen will display a warning message that the concentration is too low and an alarm will be issued.

[0044] Flame sensors, smoke sensors, etc. are placed in outdoor cable trenches, 35kV box-type power distribution devices, 10kV box-type power distribution devices, secondary equipment rooms, etc., and interfaces are reserved for uploading fire alarm warning information. When the environmental monitoring host issues an alarm, the system will automatically start and switch to the camera. If the camera has a preset function, it will automatically turn to the corresponding preset point.

[0045] In order to detect water leakage in the power distribution room in time, water sensors are installed at key locations and under the humidification pipe, dehumidification pipe and main body of the air conditioner. Once a water leak occurs, the sensor will immediately trigger a water leak alarm.

[0046] When the above monitored sensor data is abnormal, you can use your mobile phone for remote operation to control the fan, air conditioner, dehumidifier or water pump. For example, when the temperature and humidity sensor detects that the humidity in the distribution room exceeds the standard, use your mobile phone to remotely start the dehumidifier. When the temperature in the distribution room is abnormal, you can use your mobile phone to remotely adjust the working state of the air conditioner. When harmful gases exceed the safety standard, the fan is automatically started for ventilation. The time for the fan to start and stop can be set every day to ensure that the distribution room is ventilated at least once a day. When a water leak occurs, start the water pump. Through these automatic control devices, ensure that the distribution room always maintains a constant temperature and humidity.

[0047] like Figure 4 As shown in the figure, when the administrator is not present, other personnel need to enter the power distribution room. The administrator can use the mobile phone to remotely open the access control. At the same time, the administrator can also watch the video surveillance of the power distribution room in real time through the mobile phone. When the power distribution room opens the door, it will automatically trigger the camera to take a snapshot (the linkage rules can be configured according to your needs). In this way, the administrator can always know when, where, and who enters and exits the power distribution room. Video surveillance includes using mobile phones for video patrols, viewing videos through mobile phones when alarms occur, and remotely controlling cameras for video surveillance through mobile phones. It can monitor the operating status of each device in the power distribution room, realize remote monitoring, and cooperate with environmental detection to realize automatic preset position control of the camera. Comprehensive monitoring is achieved through the network high-definition ball camera / gun camera arranged at a high altitude. The camera has night vision or fill light function. In addition, when the infrared alarm based on the infrared sensor is triggered, it starts immediately and automatically switches to the camera mode. The monitored video signal is transmitted in real time through the wireless communication module (5G module). When important signals such as firefighting occur, the voice alarm module will automatically start and sound an alarm.

[0048] The above is a preferred embodiment of the present invention. It should be pointed out that, for ordinary technicians in this technical field, several improvements and modifications can be made without departing from the principles of the present invention. These improvements and modifications should also be regarded as the protection scope of the present invention.
