detailed description

In order to make the object, technical solution and advantages of the present invention clearer, the present invention will be further described in detail below in conjunction with the accompanying drawings.

As shown in FIG. 1 , an operation method for a power consumption detection device of an electric meter provided by Embodiment 1 of the present invention, the method includes:

Step S101, displaying one or more automatic meter calculation modes and their corresponding trigger areas, the automatic meter calculation modes include single-phase meter calculation mode and three-phase meter calculation mode;

Step S102, when the selection command sent by the user to the trigger area of a certain automatic entry calculation mode is obtained, the selected automatic entry calculation mode is executed, and after entering the selected automatic entry calculation mode, the user According to the corresponding data entered, the theoretical value and the actual value of the electric meter per revolution are obtained and compared, and the current health status of the rotation number of the electric meter is judged according to the comparison result; wherein, the health status includes fast, normal and Slow.

The specific process is that two automatic calculation modes can be entered respectively according to the user's selection, and the current health status of the rotation number of the electric meter can be judged.

The first automatic calculation mode is the single-phase meter calculation mode. When the selection command sent by the user to the trigger area of the single-phase meter calculation mode is obtained, the single-phase meter calculation mode is executed, and after entering the single-phase meter calculation mode, Obtain the current value, voltage value and ammeter constant entered by the user, obtain the theoretical value T of the ammeter per revolution, and obtain the revolution number entered by the user, and obtain the actual value K of the ammeter per revolution according to the start time and end time of the record; and Compare the obtained theoretical value T of the meter per revolution with the actual value K of the meter per revolution, and judge the current health status of the meter's revolutions based on the comparison results. Wherein, the theoretical value T=3600/current value/voltage value/meter constant for each revolution of the electric meter. As an example, select the current change is relatively small, measure the current value, voltage value, and ammeter constant value of the single-phase meter measured on site, manually input into the calculation mode of the single-phase meter, click the calculation button, the information of the single-phase meter is calculated and output single-phase The theoretical value of the time per revolution (pulse) of the phase meter. The input parameters include: current (A, default 5A), voltage (V, default 0.22kV), meter constant (C, default 800). The output items include: the theoretical value (T) of the time spent per revolution (pulse) of the meter, and the judgment result of the speed of the meter (very fast, normal, and slow).

The second automatic calculation mode is the three-phase meter calculation mode: when the selection command sent by the user to the trigger area of the three-phase meter calculation mode is obtained, the three-phase meter calculation mode is executed, and after entering the three-phase meter calculation mode, Display the input current value mode and its corresponding trigger area; among them, the input current mode includes primary current value and secondary current value;

When the selection command issued by the user for the trigger area of a certain input current value mode is obtained, the input current value mode is executed, and after entering the input current value mode, the corresponding data entered by the user is obtained to obtain the theoretical value T of the meter per turn. , and obtain the number of revolutions entered by the user, and obtain the actual value K of the meter per revolution according to the start time and end time of the record; and

Compare the obtained theoretical value T of the meter per revolution with the actual value K of the meter per revolution, and judge the current health status of the meter's revolutions based on the comparison results.

According to the field environment, what is actually measured is the primary current value. Therefore, when the selection command issued by the user for the trigger area of the primary current value is obtained, the primary current value is executed. After entering the primary current value, the user-entered multiplier, triple Phase current value, voltage value, ammeter constant and power factor to obtain the theoretical value T of the ammeter per revolution, and obtain the number of revolutions entered by the user, and obtain the actual value K of the ammeter per revolution according to the start time and end time of the record; and Compare the obtained theoretical value T of the meter per revolution with the actual value K of the meter per revolution, and judge the current health status of the meter's revolutions based on the comparison results. Among them, the theoretical value T=3600*3*multiplier/sum of three-phase current values/voltage value/meter constant/1.732/power factor per revolution of the meter. As an example, according to the input selection current change is relatively small, measure the current value, voltage value, multiplier, ammeter constant value of the three-phase meter measured on site, manually input the primary current value in the three-phase meter calculation mode, click the calculation button , The three-phase meter information calculates and outputs the theoretical value of the time per revolution (pulse) of the single three-phase meter. The input parameters include: multiplier (default 5), three-phase current (A, default 5A), voltage (V, default 0.4kV), meter constant (C, default 800), power factor (default 0.9). The output items include: the theoretical value (T) of the time spent per revolution (pulse) of the meter, and the judgment result of the speed of the meter (very fast, normal, and slow).

According to the on-site environment, the primary current value cannot be measured, and only the secondary current value can be measured actually. Therefore, when the selection command issued by the user for the trigger area of the secondary current value is obtained, the secondary current value is executed and waits to enter After the secondary current value, get the three-phase current value, voltage value, meter constant and power factor entered by the user, get the theoretical value T of the meter per revolution, and obtain the revolution number entered by the user, according to the start time and end time of the record , to obtain the actual value K of the electric meter per revolution; and compare the obtained theoretical value T of the electric meter per revolution with the actual value K of the electric meter per revolution, and judge the current health status of the electric meter revolution according to the comparison result. Among them, the theoretical value T=3600*3/sum of three-phase current values/voltage value/meter constant/1.732/power factor per revolution of the meter. It should be noted that the difference between the input information of the secondary current value and the primary current value is that the primary current value has a multiplier, while the secondary current value does not.

In the above two automatic calculation modes, when the actual value K≤0.9*theoretical value T of the meter per revolution, it is judged that the revolution of the meter is too fast; when 0.9*the theoretical value T of the meter per revolution<the theoretical value T of the meter per revolution When the actual value K<1.1*the theoretical value T of the meter per revolution, it is judged that the revolution of the meter is normal; when the actual value of the meter per revolution K≥1.1*the theoretical value T of the meter per revolution, it is judged that the revolution of the meter is slow.

Step S103, displaying the meter alarm type judgment mode and its corresponding trigger area, when the selection instruction sent by the user to the trigger area of the meter alarm type judgment mode is obtained, the selected meter alarm type judgment mode is executed, and waiting After entering the meter alarm type judgment mode, one or more alarm messages and their corresponding trigger areas are displayed, and when the selection instruction issued by the user for the trigger areas of the alarm information is obtained again, the corresponding alarm information is displayed.

Specifically, according to the different information prompted by the meter dial, the user can select the trigger area corresponding to the same information display on the device, trigger the selected trigger area, and obtain a graphic description of the state of the meter or the type of failure. It can be understood that the meter alarm type judgment mode is used to guide and know the information currently prompted by the meter through graphic descriptions when the user cannot determine the information prompted by the dial of the current meter.

It should be noted that the trigger area includes but not limited to executable buttons, links, etc. When the trigger area is a button, it can be a virtual button or a physical button.
