Description

With the rapid development of the national economy and smart grid, coupled with the rising of the real estate industry, there are more and more supporting substations. In order to save precious land resources, it is no longer possible to build substations that need to occupy additional land on the outdoor surface. To meet the demand, these substation equipment are more designed as compact underground arrangements. Especially in areas with high population density, substations with this "full underground" structure form occupy a huge proportion.

However, since the underground substation itself is installed underground, water leakage often occurs whenever it rains, especially in severe weather conditions such as heavy rain, typhoon, and flood disasters, and the degree of water seepage is particularly serious. If the water leakage phenomenon is not treated in time, the water level will rise rapidly due to the water seepage cannot be discharged naturally, causing equipment failure. In recent years, there have been several cases of water leakage in underground substations, some of which were even completely submerged, and the power transmission and distribution equipment was scrapped, causing heavy losses. Therefore, water leakage has become an important unsafe condition for the safe operation of underground substations. one of the factors.

And in order to prevent the underground substation from causing damage to the power transmission and distribution equipment of the underground substation due to water leakage, the method used for the water leakage in the prior art is manual inspection, and due to the lack of necessary Monitoring means, in order to prevent accidents, the operating personnel have to check the underground substations in the jurisdiction one by one every heavy rainy day. Even if all the operating personnel are dispatched and exhausted by this manual inspection method, it is still difficult to make a timely response to the occurrence of water leakage. Effective processing, and the manual inspection method still has the problem of missed detection and false detection caused by the different detection levels of operators.

To sum up, there is an urgent need for a monitoring device that can continuously monitor the leakage of underground substations continuously. The relevant information is transmitted to the relevant staff, so that they can "perceive" the water leakage situation of the substation in time, so as to respond quickly to the clear target. Eliminate the leaking water before it causes equipment failure. The monitoring device is of great significance to eliminate the safety hazard caused by the leaking water in the underground substation, ensure the safe operation of the substation, and improve the reliability of power supply.

A remote monitoring device for leaking water in an underground substation of the present invention, the specific steps of use are as follows:

1). When water leakage occurs in underground substation 1, the water level first touches the lower early warning sensor A1, and the early warning sensor sends an early warning signal to the monitoring and judgment module A3. At this time, the monitoring and judgment module retains its early warning signal command and does not act temporarily;

2). When the water leakage phenomenon causes the ground water level of underground substation 1 to continue to rise to the alarm sensor A2, the alarm sensor sends an alarm signal to the monitoring and judgment module A3. At this time, the monitoring and judgment module first monitors the signal sending status of the early warning sensor A1, If both the early warning sensor and the alarm sensor are in the signal sending state, the monitoring and judging module judges that water leakage has occurred, and immediately sends an alarm signal to the data acquisition and processing component B, and the data acquisition and processing component performs digital filtering through its digital filtering module B1 process, filter out interference data and invalid data, and then send the signal data to the alarm judgment module B3 after the inspection of the digital validity check module B2, and finally the message generation module B4 converts the correct signal data sent by the alarm judgment module into In the form of a message, it is sent to the subsequent communication module C;

4). In the above step 1), if the monitoring and judgment module A3 detects the warning signal sent by the warning sensor A1 within the preset length of time, but the warning sensor A2 does not send out a signal, it is judged as mild Leaking water (in this embodiment, the preset time period is 1 hour), at this time, the monitoring and judgment module skips the judgment condition of the alarm sensor A2, and directly sends an early warning signal to the data collection and processing component B, requiring the staff to go to investigate and deal with ;

The data acquisition and processing component B has two sets of signal processing modes, which are the alarm signal processing mode and the early warning signal processing mode.

5). In the above step 2), when the monitoring and judgment module A3 receives the alarm signal from the alarm sensor A2 and checks the signal transmission status of the early warning sensor A1, if the early warning sensor is not in the early warning signal transmission status, it will be judged as a false alarm , without subsequent processing.
