The invention is suitable for the technical field of power data processing, and provides a power system database data exception monitoring method and device and electronic equipment, wherein the method comprises the steps of obtaining a to-be-monitored data table in a data table of a power system and a source business system database corresponding to the to-be-monitored data table; determining a business relationship of the to-be-monitored data table according to a source business system database corresponding to the to-be-monitored data table; and according to a preset monitoring condition corresponding to the service relationship with the to-be-monitored data table, monitoring each piece of data in the to-be-monitored data table, and when it is monitored that a certain piece of data in the to-be-monitored data table is abnormal, sending an abnormality prompt message indicating that the piece of data is abnormal to the terminal equipment. According to the invention, the to-be-monitored data table is monitored based on the business relationship of the to-be-monitored data table, the abnormal monitoring result can be obtained in time, and alarm and correction can be carried out based on the abnormal monitoring result, so that the accuracy of the data in the data table in the data-in-station is improved.

The invention discloses an electromechanically-integrated gas density relay and system. The gas density relay comprises a mechanical part and an electronic part. The mechanical part comprises a pressure detector, a temperature compensation element and a signal generator. The electronic part comprises a pressure sensor, a temperature sensor, a microprocessor and a first electronic signal contact. The first electronic signal contact is connected with the signal generator in series or in parallel, or is connected to a control loop corresponding to the signal generator in series or in parallel. The microprocessor is connected with the pressure sensor and the temperature sensor to obtain a pressure value and a temperature value and process the pressure value and the temperature value to obtaina gas density value; the microprocessor is further connected with the electronic signal contact, and when the monitored gas density value is smaller than or larger than a set density value, the microprocessor receives a first notice contact signal output when the first electronic signal contact acts. By means of the gas density relay, the gas density value of electrical equipment can be accuratelymonitored to find gas leakage in time, and thus the safe operation of a power grid is guaranteed.
