Wechat paid the electricity bill, why can't I get the text message?

Electricity, that is, electricity. It is the electricity cost consumed by an enterprise, unit and individual in a certain period of time.

No matter whether users actually use electricity or not, they need to bear the electricity bill. Among the production costs of electric power enterprises, there are some costs that do not change with the power generation and supply, such as the maintenance and depreciation of fixed assets, which are called fixed costs; The other part is the cost that changes with the change of power generation and supply, such as the cost of power generation fuel consumed, which is called variable cost. It is a common method in the world to divide the electricity charges charged by power companies into basic electricity charges and electricity charges, and compensate the above two costs respectively. This method is called two-part electricity price. It is beneficial for users to bear the cost of power generation and power supply fairly and reasonably, and promote users to improve the power load rate, thus reducing the cost of power generation and power supply and the total electricity price level of power enterprises.

There are two ways to calculate the basic electricity charge, one is based on the maximum electricity demand, and the other is based on the capacity. China implements two-part electricity price for users whose electricity consumption is above 3 15kv a.

Electricity charge calculated according to actual electricity consumption. Electricity price is used to compensate the variable cost of power enterprises with the change of power generation and power supply. For small users such as residents, the electricity fee is all the electricity fees that should be paid; For users who implement the two-part electricity price, the electricity price is only a part of the electricity payable, and the basic electricity price is the total electricity payable. The electricity charge is calculated according to the reading of the active electric energy meter in the charging electric energy metering device installed by the electric power enterprise at the user's place.

Because the watt-hour meter count is a cumulative value, it should be the difference between the final reading and the initial reading when calculating the electricity consumption in the specified period. When installing current transformer and voltage transformer in electric energy metering device, they should be multiplied by the ratio of current transformer and voltage transformer respectively. The transformation ratio of current transformer (or voltage transformer) is the ratio of rated current (or voltage) of primary winding and secondary winding of current transformer (or voltage transformer).
