Technical Field
The invention belongs to the technical field of electric power, and particularly relates to a switching-on and switching-off control system of an electric energy meter and a control method thereof.
Background
With the acceleration of life rhythm and the development of technology, the electric energy metering and charging gradually develop towards time-sharing sectional charging and prepayment. In prepaid usage scenarios, it may happen that the user load is disconnected when the prepaid charge is consumed. In the process, people often do not pay the remaining electricity charge of the user because of work, and therefore the electricity is sometimes cut off and the reason is not known. Meanwhile, when the power is cut off, the load current of a user is possibly larger when the user is in a peak period of the power load, and the impact on the user and equipment is larger if the user trips in the situation. Meanwhile, in the metering process, metering inaccuracy sometimes occurs. Based on the situation, the invention provides the switching-on and switching-off control strategy and method for the electric energy meter.

3. when the pre-stored cost is lower than 0, the system is about to trip and cut off the power, but before the system is tripped and cut off the power, the system can automatically detect the state of the system, the state detection judges the state of the system by detecting the position of a trip switch, when the switch is in a closed state and the voltage of the system is collected to be a normal value, the default is that the system is in a closed state, and at the moment, the switch can be tripped. When the tripping switch position is detected to be in an open state or the tripping switch is in a closed state but the detected voltage is 0, no tripping action is generated. On the contrary, if the user causes the tripping operation outage because of the arrearage after, the user pays the fee again after, the system can automatically close a floodgate, the floodgate also satisfies certain condition, its condition is: the trip switch is in the off position and the system voltage is normal before it can be switched on. The implementation of the measures ensures the accuracy of tripping and closing of the system;
4. when the system is tripped due to defaulting, in order to ensure the safety of tripping and reduce the system impact, the tripping action is related to the load value carried by the system, when the load value of the system is less than a certain value, the tripping action is sent, and when the load value is more than the certain value, the system can not send the tripping action.
