Do you know some Functions of the Three-Phase Four-Wire Fee-Controlled Smart Energy Meter?

As a Din Rail Meter Wholesale, share with you.

1. Data wheel display function

The parameter wheel display can be realized. The parameters (not more than 99 items) and time of the wheel display can be set in advance, and the order of the parameter wheel display can also be set arbitrarily. The specific settings are as follows:

Display time per screen: the display time of each item of data in the round display. If this time is set to 0, the energy meter will be processed for 5 seconds.

Number of auto-cycle display screens: The number of screens for the wheel display parameters can be selected as required.

Number of key cycle display screens: The number of key display screens can be selected as required.

Automatically display data items: display data items edited by users as required.

Rotate content settings:

The display code of the automatic cycle display data item includes the identification code and the serial number. The data identification code is the identification code of the DL / 645-2007 communication protocol corresponding to the content to be displayed. The serial number is the data item in its corresponding identification code. Corresponding serial number, when the display code of the automatic cycle display data item is set, the upper 1 byte is the serial number, starting from 00.

2. Button display function

The three-phase four-wire fee-controlled intelligent electric energy meter can realize the key display of parameters by pressing the key display button on the panel. When the key display button of the meter is pressed, the meter enters the key display. If the key is pressed again, the next item of data is displayed. If there is no more key operation, the meter will automatically exit the key display state and enter the wheel display state after 60 seconds.

Up to 99 items can be set for the key display data item, which is the same as the automatic cycle display data item setting.

3. Power-off recording function

Whether to judge whether the power is off depends on 87.Un and 87.01Ib. When the three-phase voltage is lower than the critical voltage of the meter by 60% × Un, and the three-phase current is not greater than Ib × 5%, it is judged as power-off and records The total number of power failures, the time and end time of the last 1 ~ 10 power failures.

Note: (1) The power-down judgment is made regardless of whether the power meter is working normally. If the power meter is working normally, the power-down state needs to last for 15 seconds to start recording the power-down record.

(2) After the electricity meter stops working, use the power meter reading battery to detect the current once, and then no longer use the battery to detect the current until the electricity meter works with voltage, and then judge the end of the power failure.
