Name: SH-ZF07 energy meter wiring simulation system

Functional features

1, can simulate three-phase three-wire, three-phase four-wire high-voltage and low-voltage metering of the scene of various wiring.

2, simulation device according to customer requirements, customized into 1-4 sides.

3, the simulation device is independent of each side, can be 1-4 people at the same time to carry out different operations, do not interfere with each other. Each side can set up different topics, can set up different voltages, currents, phases, can be added at different times to power off, can only open any of the several sides.

4, the software can be alone on a side of the control, you can also control all sides at the same time.

5, each side can hang 1-2 fast mechanical meter, electronic meter, multi-function meter.

6、Each kind of wiring is analyzed according to 2 kinds of unnecessary methods, considering the influence of different reactive power measuring principles on active and reactive power meter measurement of 3-phase 3-wire 60°reactive power meter, 3-phase 4-wire 90°crossing reactive power meter and multi-functional electronic meter when wrong wiring.

Method 1: Analyze according to three-phase three-wire 60° reactive power meter or three-phase four-wire 90° cross-wire reactive power meter when hanging 2 mechanical meters. In particular, the influence of the voltage divider on the active and reactive power meters due to the connection of the reactive power coil across the phase break is taken into account.

Method 2: Analyze the reactive power vector diagram according to the principle of true reactive power (also called calculated reactive power) when hanging a single active mechanical meter, active electronic meter, or multifunction meter.

7、Derive the vector diagrams, split-phase power expressions, combined-phase power expressions (simplified to the simplest form), and corrected coefficient expressions (simplified to the simplest form) for active and reactive meters, with the company's push-down rate reaching 100% and simplification rate reaching 100%.

8、Derive the current phase active meter and reactive meter turntable rotation direction, wrong power value, correct power value, correction coefficient value, and true reactive power value (for comparing true reactive power and cross-line reactive power or 60-degree reactive power).

9、Drawing the wrong wiring vector diagram of active and reactive meters and the correct wiring vector diagram for comparison.

10, the vector diagram can be enlarged to display.

11、Calculate the catch-up power and correction factor.

12、Draw the curve diagram of split-phase power, combined-phase power and correction factor of 0-359°.

13, with a virtual wire checker function, can check the three-phase three-wire and three-phase four-wire wiring errors.

14, the software can be separated from the simulation device used alone, to facilitate students and teachers more convenient to use the software.

15, wiring diagrams and vector diagrams can be saved and printed.

16, simulation device built-in each side of a three-phase volt-ampere meter, the computer can display the actual vector at the end of the table.

17, can automatically determine whether the line is correct.

18, the software has a system question bank, included in the “operation of the power metering device error detection and analysis of wiring” (China Electric Power Press, published by Meng Fanli) in all the examples, and marked the cited chapters and pages, easy for users to access.

19, the software has a user question bank, users can add, modify, delete the title.

20, the program provides a carefully organized, written “simulation wiring training materials”, “instructions for use”, “operation steps”, “analysis”, “simulation fault location map”, “skills competition referee table”, “skills competition rules”, “wiring inspection records”, “on-site inspection records.

21, with voice prompts and voice alarm function.

22, with a countdown function.

23, in the transformer terminal row and the joint junction box in the middle of the increase in metering screen terminal row, imitating the substation metering screen wiring.

24、Comprehensive hidden wire hole design, to ensure that all unused wires are put into the hidden wire hole.

25, the analog device has three communication ports, can be accessed from the bottom of the two sides of the communication line, can also be accessed from the top of the communication line.

26, the computer and the simulation device can be used between the limited communication or wireless communication (to be customized).

27, unique cooling air duct design, each side of just 1 fan, while using temperature control technology, automatic start and stop the fan, so that the noise is minimized.

28、Special power-down and rerouting technology makes the operation safer.

29, unique spare key design, can increase the software and hardware functions as needed.

30, regular software routine upgrade, so that users always want to use the latest software. Simulation device software is free software, users can download, copy, install and use for free, our company regularly releases the latest software to the Internet, so that it is easy for users to upgrade and understand the latest technology of the simulation device.
