Problems solved by technology
[0002] 110kV and below substations mostly adopt the unattended mode, and the water level information of some underground substations and substation underground cable layers cannot be grasped by operation and maintenance personnel in real time
Although these areas will be equipped with an automatic drainage system, in actual operation, there will still be problems that the accumulated water cannot be discharged in time due to reasons such as the failure of the water pump to start normally.
Since the current automatic drainage system in the unattended substation is not equipped with a condition monitoring system, it cannot be detected and dealt with in time after its failure. safe operation of the equipment, therefore, it is imminent to solve this problem

Embodiment Construction
[0013] A fault alarm device for an automatic drainage system of an unattended substation, comprising a float level sensor 2 arranged in a reservoir 1, the float level sensor is connected to a single-chip microcomputer 3, and receives a start signal of the single-chip microcomputer; the float level sensor Connect with single-chip microcomputer by receiving circuit 4, transmit water level signal to single-chip microcomputer; Single-chip microcomputer is connected with GSM short message warning module 5, sends short message by GSM short message warning module; A voltage stabilizing chip power supply module 6 is connected with single-chip microcomputer;
[0014] When working, the microcontroller is initialized, and then the water level is tested every 5 seconds. If the water level reaches the warning level, it will get a different level than usual. At this time, a text message will be sent, and then the program will enter an endless loop to prevent sending text messages all the time...

The present invention discloses an unattended transformer substation automatic drainage system fault alarm device. The unattended transformer substation automatic drainage system fault alarm device comprises a floating ball liquid level sensor arranged in an impounding reservoir, the floating ball liquid level sensor is connected with a single-chip microcomputer via a reception circuit, receives a starting signal of the single-chip microcomputer and transmits a water level signal to the single-chip microcomputer, the single-chip microcomputer is connected with a GSM short message alarm module, the GSM short message alarm module sends a short message, and a voltage stabilization chip power supply module is connected with the single-chip microcomputer. The unattended transformer substation automatic drainage system fault alarm device of the present invention is reasonable in structure and good in working performance. By a water level sensor, a GSM module uploads a drainage system fault alarm short message to the mobile phones of the operation and maintenance personnel, so that a drainage system fault can be discovered timely, the transformer substation ponding possibility is avoided, the safe and stable operation of the underground equipment is guaranteed, and the reliability of a power grid is improved greatly.
Description
technical field [0001] The invention relates to a failure alarm device for an automatic drainage system of an unattended substation. Background technique [0002] 110kV and below substations mostly adopt the unattended mode, and the water level information of some underground substations and substation underground cable layers cannot be grasped by operation and maintenance personnel in real time. Although these areas will be equipped with an automatic drainage system, in actual operation, there will still be problems that the accumulated water cannot be discharged in time due to reasons such as the failure of the water pump to start normally. Since the current automatic drainage system in the unattended substation is not equipped with a condition monitoring system, it cannot be detected and dealt with in time after its failure. The safe operation of the equipment, therefore, it is imminent to solve this problem. Contents of the invention [0003] The object of the presen...
