And, the theoretical basis of the temperature rise measurement of the binding post of this table is carried out to the inside temperature sensor of electric energy meter: according to a heat conduction formula followed by a heat conduction mode:wherein Q is heat flow, lambda is heat conductivity coefficient of the material, and the parameter representing the heat transfer performance of the materialNumber Ac represents the cross-sectional area, L is the heat transfer distance; delta T is the heat transfer temperature difference and the negative sign indicates that the direction of heat transfer is opposite to the direction of temperature rise.

And 220, determining the average temperature, the temperature change rate and the temperature fluctuation range of the electric energy meter corresponding to the temperature data according to the temperature data.
Wherein the average temperature (T M ) The average temperature value over a certain period of time may be an arithmetic average of temperature data of N sampling points. Rate of temperature change (T) R ) For the change rate of the temperature in the adjacent time interval, the calculation method is the ratio of the temperature difference value of two adjacent sampling moments to the sampling period.
