Embodiment 1
[0079] The sensor device control method for power metering provided by the embodiment of the present invention is as follows: figure 1 As shown, as a preferred embodiment, the data analysis method provided by the embodiment of the present invention is as follows:
[0080] (1) Calculate the line voltage transformer voltage through the statistical program, and record the historical 30-day data sampled at a period of 5 minutes in the created database data.
[0081] (2) Do the average number sequence for the statistical array, which adopts the following formula:
[0082] Average sequence=[actual value (phase a)+actual value (phase b)+actual value (phase c)] / 3.
[0083] (3) Calculate the degree of three-phase deviation
[0084] Phase A deviation = actual value (phase a) - average sequence.
[0085] Phase B deviation = actual value (phase b) - average sequence.

Abstract
The invention belongs to the technical field of electric power measurement, and discloses a sensor device for electric power measurement and a control method. The control method comprises the steps of: detecting current and voltage data by means of current and voltage detectors; detecting temperature and humidity data by means of temperature and humidity sensors; performing infrared detection by using an infrared detector; setting electric power metering parameters, and setting normal threshold ranges of temperature, humidity and infrared radiation quantity; when the temperature, humidity andinfrared radiation quantity exceeds preset threshold values, performing corresponding adjustment by means of a pressure regulator, a heat dissipation device and a dehumidification device; analyzing power data by using an analysis program; and sharing the power data by means of a sharing program. The sensor device can monitor environmental data of the device in real time, avoids abnormality of thedevice caused by over-high temperature and humidity, can automatically adjust the environmental temperature and humidity data to ensure stable operation of the device, and can automatically alarm andinterrupt when encountering abnormality, and guarantees the operation safety of the device.
Description
technical field [0001] The invention belongs to the technical field of power metering, and in particular relates to a sensor device and a control method for power metering. Background technique [0002] Electricity is an energy source powered by electrical energy. The transmission of electric energy, together with transformation, distribution and consumption, constitutes the overall function of the power system. Through power transmission, power plants and load centers that are far apart (up to thousands of kilometers) are connected, so that the development and utilization of electric energy go beyond geographical restrictions. Compared with the transmission of other energy sources (such as coal transportation, oil transportation, etc.), power transmission has small loss, high efficiency, flexibility and convenience, easy regulation, and less environmental pollution; power transmission can also connect power plants at different locations, and implement peak-valley adjust. ...
