When the data is abnormal, the main control circuit board 2 controls the alarm light 5 to flash.

[0026] After adopting the above structure, first, the monitoring system includes a monitoring column 1 and a liquid level buoy collector 7, and the liquid level buoy collector 7 is used to be placed in a water seal well 9 and / or an accident oil pool 10 and / or a total outlet, so that the status information of the oil leakage can be collected by the liquid level buoy collector 7, so as to provide further protection. The monitoring column 1 is provided with a main control circuit board 2, a data display terminal 3, a wireless transmission terminal 4, a power supply system and an alarm light 5, wherein the components are electrically connected to provide a complete monitoring system, so that real-time monitoring can be carried out and the monitoring data can be transmitted. The main control circuit board 2 and the liquid level buoy collector 7 are electrically connected or wirelessly connected. The network connection enables the main control circuit board 2 to obtain the information collected by the liquid level buoy collector 7 and process the collected data. The main control circuit board 2 transmits the data collected by the liquid level buoy collector 7 to the operator's mobile terminal through the wireless transmission terminal 4, so that the operator can monitor the liquid level data of the water seal well 9, the accident oil pool 10 and the main outlet in real time at a long distance, which is convenient for the operator to perform real-time monitoring. The collected data is displayed through the data display terminal 3, so that the operator can see the monitoring data on the monitoring column 1. When the data is abnormal, the main control circuit board 2 controls the alarm light 5 to flash, reminding the operator that the data is abnormal and issuing a danger warning.

[0027] Secondly, through the monitoring system, operators can monitor whether there is oil leakage, so that oil leakage accidents can be handled quickly and timely to prevent oil pollution. When oil leaks, the real-time status of the oil can be monitored to prevent the oil from being in a dangerous state and causing further harm. By monitoring the data of the water seal well 9, the accident oil pool 10 and the main discharge port, the entire substation can be monitored throughout the process to fully ensure safety.

[0028] Based on the above structure, the prior art uses a water seal well 9 to extinguish the burning oil. The monitoring system can monitor whether the water volume in the water seal well 9 is in a normal state and whether the oil therein is in a high-temperature ignition state. Therefore, when the monitoring data is abnormal, it can be handled in time to prevent further harm.

[0029] In order to enable the liquid level buoy collector 7 to collect data, Figure 3 As shown, the preferred liquid surface buoy collector 7 of the present invention is provided with a water-oil density sensor, a conductivity sensor and a temperature sensor, wherein the water-oil density can be obtained by the water-oil density sensor, thereby obtaining the volume of leaked oil, and when the leaked oil is too much, the operator can deal with it in time; the conductivity sensor can be used to obtain the conductivity of the oil to prevent the operator from contacting and causing danger; the temperature sensor can be used to obtain the liquid temperature, thereby obtaining whether the oil is in a flammable state or a high-temperature flammable state, so that the operator can deal with it in time when the oil is on fire.

[0030] In order to collect more sufficient data, the present invention preferably comprises a liquid surface buoy collector 7 including a water surface collection part, a water collection part and an underwater collection part. With this structure, the surface, water and underwater data can be collected simultaneously, and the real-time status of the oil can be analyzed simultaneously by combining the data from different parts, thus avoiding the error caused by a single collection and making the collected data more accurate.

[0031] In order to monitor external sounds, the present invention preferably monitors that the column 1 includes a noise monitor, and the noise monitor includes a noise sensor. The decibel size is measured by the noise sensor, and the data is processed by the main control circuit board 2 and transmitted to the operator's mobile terminal through the wireless transmission device 4. By monitoring the noise, it is possible to monitor whether an explosion or the like occurs when oil leaks, and to take further protective measures so that timely handling can be carried out when danger occurs.

[0032] In order to monitor the external temperature and humidity, the present invention preferably monitors that the column 1 includes a temperature and humidity monitor, and the humidity monitor includes a temperature sensor and a humidity sensor. The temperature and humidity of the external environment are measured by the temperature sensor and the humidity sensor, and the state of the oil is fully analyzed in combination with the data of the external environment, so that the dangerous situation can be comprehensively analyzed to provide further protection.

[0033] In order to be able to observe the position of the liquid level, the present invention preferably includes a monitoring column 1 including a liquid level monitor 6. The main control circuit board 2 and the liquid level monitor 6 are electrically connected. The liquid level buoy collector 7 transmits the position information of the water surface to the main control circuit board 2. The main control circuit board 2 processes the water level information and controls the displayed liquid level in the liquid level monitor 6 to drop, so that the changes in the liquid level can be seen more intuitively, so that the operating personnel can observe the changes in the liquid level in the water seal well 9 through the liquid level monitor 6 of the monitoring column 1, thereby knowing whether the water volume in the water seal well 9 is sufficient and whether the oil is excessive when the oil is discharged into the water seal well 9, and then further protection work can be done.

[0034] In order to make the main control circuit board 2 resistant to lightning strikes, the present invention preferably uses a lightning-resistant circuit board for the main control circuit board 2. Since the monitoring column 1 is located in a complex outdoor environment, and the main control circuit board 2 is the hub for controlling the entire monitoring system, a lightning-resistant circuit board is used so that the main control circuit board 2 can resist lightning strikes, thereby extending its service life.

[0035] In order to utilize solar energy, the present invention preferably adopts solar energy to power the power supply system in the main control circuit board 2, and a solar circuit board is provided on the monitoring column 1, so that solar energy can be used for power supply, thereby saving electricity. In the prior art, oil leakage is usually caused by an accident in the transformer. When a power outage is caused by oil leakage in the transformer in the substation, the monitoring system can still work normally.

[0036] In order to optimize the wireless transmission terminal, the present invention preferably uses the wireless transmission terminal 4 in the main control circuit board 2 as a loRaWAN wireless transmission terminal. The loRaWAN wireless transmission terminal has many advantages such as wide coverage, many connectable terminals and strong penetration, and is suitable for the complex environment of substations. Among them, the loRaWAN wireless transmission terminal adopts the LoRaWAN protocol. The LoRaWAN protocol is optimized for low-power, battery-powered sensors and includes terminal nodes of different levels to optimize the balance between network delay and battery life.

This embodiment mainly includes an oil storage pit 8, a water seal well 9, an accident oil pool 10, a rainwater well 11, a main drain and an oil leakage monitoring system. The accident oil pool structure discharges the liquid through the main drain. When the transformer in the substation leaks oil, the burning oil is extinguished by the water in the water seal well 9, and then discharged into the accident oil pool 10 for oil-water separation. After the oil and water are separated in the accident oil pool 10, the water is discharged into the rainwater well 11, and the oil is stored in the accident oil pool 10 for recycling.
