In order to solve the above problem, the disaster prevention auxiliary system provided in the embodiment of the present invention may further perform water level detection, and automatically start the drainage device to drain water according to a result of the water level detection. The substation disaster prevention auxiliary system 10 will be further described with reference to the drawings.
Optionally, fig. 3 is a schematic structural diagram of another substation disaster prevention auxiliary system according to an embodiment of the present invention, and on the basis of the foregoing embodiment, referring to fig. 3, the substation disaster prevention auxiliary system 10 further includes a water level detection module 140 and a drainage device 150;
the water level detection module 140 is arranged at a preset height of a cable trench of the transformer substation, the water level detection module 140 is connected with the main control module 120, and the water level detection module 140 is used for outputting a first trigger signal when detecting that the water level of the cable trench reaches or exceeds the preset water level;

Specifically, the cable trench is a necessary place for cables from buildings to various places in the transformer substation, and accumulated water in the cable trench easily causes problems of cable aging, short circuit and the like. This embodiment detects whether ponding in the cable pit has reached or exceeded and predetermines the water level through set up water level detection module 140 in the preset height department of cable pit. The preset height is typically selected as a low lying position of the raceway so that the water level detection module 140 can detect whether water has accumulated in the raceway at a first time. The water level detecting module 140 may be, for example, a water intrusion probe, and when the water level reaches a preset height position, the water intrusion probe outputs a switching value signal, which is the first trigger signal. When receiving the first trigger signal, the main control module 120 outputs a second control signal to instruct the drainage device 150 to perform a corresponding action.
The signal control end of the drainage device 150 is connected to the main control module 120, so that the main control module 120 can output a corresponding control signal to the drainage device 150 according to the current water level condition. Specifically, when the water level detection module 140 outputs the first trigger signal, the main control module 120 determines that the water level in the cable trench has reached or exceeded the set water level, and accumulated water already exists in the cable trench, and the main control module 120 outputs the second control signal to the power unit of the drainage device 150 to control the power unit of the drainage device 150 to drive the drainage device 150 to drain the accumulated water in the cable trench. The drainage device 150 may be, for example, a water pump, which is disposed in the cable trench, and when the accumulated water reaches a set water level, the main control module 120 automatically starts the water pump to drain the accumulated water in the cable trench, so that the possibility of the accumulated water occurring in the transformer substation during heavy rain can be greatly reduced.

For example, when any one of the water intrusion probes outputs a trigger signal, the main control module 120 outputs a second control signal.
Of course, the water level detection module 140 and the drainage device 150 can be arranged at other low-lying positions of the transformer substation, whether accumulated water exists in the low-lying positions or not can be detected, and the accumulated water is drained out through the drainage device 150 at the first time when the accumulated water exists in the low-lying positions, so that the situation that the accumulated water is accumulated more and the normal operation of the transformer substation is endangered is avoided.
