The YBPX-DJF101 three-phase electric energy meter wiring simulation device consists of a simulation metering cabinet, computer simulation system control software, communication converter, fault simulator, electric energy meter, etc. Under the control of a PC, it is possible to intelligently simulate various wiring modes of three-phase three wire and three-phase four wire metering devices, and display relevant information of various wiring modes through a computer window.

The function of simulating wiring for different energy meters: it can simulate the joint wiring simulation of electronic, mechanical active and reactive energy meters and the wiring simulation of electronic multifunctional meters;

Wiring functions with different arrangements and combinations: three-phase three wire connection via PT and CT (CT four wire system); Three phase three wire connection via PT and CT (CT simplified wire system); Three phase four wire connection via PT and CT (CT six wire system); Three phase four wire connection via PT and CT (CT simplified wire system); Three phase four wire connection via CT (CT six wire system); Three phase four wire direct connection; Implement TV and TA grounding and ungrounded simulation tests;

The device is designed to mimic the structure of a measuring cabinet, with three operating surfaces A, B, and C. Each surface is completely independent and uses an independent programmable three-phase power supply, independent simulation circuit, and independent communication circuit to ensure that each surface can be used independently. Any operator error on one surface will not affect the operation of other personnel. If there is a voltage short circuit or current open circuit on any surface, the other surfaces can work normally.

Automatic drawing and calculation function: It can automatically draw actual wiring diagrams and vector diagrams based on the selected combination of wiring elements; Can automatically calculate the active power expression and reactive power expression for each wiring combination; Automatically calculate the active power correction coefficient, correction rate, recovery power, and reactive power correction coefficient, correction rate, and recovery power for each wiring combination; Capable of automatically calculating the actual demand of a multifunctional energy meter for each wiring combination;

The function of changing incorrect wiring: On each panel, there is a dedicated energy meter tail junction box and TV for changing wiring TA wiring terminal block; For incorrect wiring test questions with TV, TA short circuit and open circuit, the wiring can be corrected through a dedicated "restore button";

The function of intelligent analysis of wiring process and results: After setting the wrong wiring, the computer can automatically display the measured vector diagram of the wrong wiring, the theoretical vector diagram of the wrong wiring, the measured vector diagram of the correct wiring, the joint wiring diagram of the wrong wiring, the expression of the wrong power, the voltage and current connection method, the correction factor, etc; During the process of changing wiring, the vector diagram can be displayed in real-time; After changing the wiring, the computer can automatically display the corrected voltage, current, and phase values, and can automatically draw the phasor diagram, wiring diagram, power expression, and correction coefficient after changing the wiring, which is convenient for teachers to judge;

Test question bank function: Provide a test question bank that meets the national requirements for electrical skills training and assessment standards. The test question bank is divided into four fixed forms: junior, intermediate, senior, and technician. Different types of extended test question banks that meet one's own requirements can be established, which can be edited and modified; You can freely select or combine test questions from existing question banks. Test questions can be combined to set query conditions and automatically memorized for easy management, querying, modification, deletion, and printing;

Query, assessment, statistics, and printing functions: You can search based on any of the candidate's affiliation, name, admission ticket number, or teacher name; Exam papers can be printed, including information such as candidate's affiliation, name, admission ticket number, score, answer time, set time, wiring method for each question, vector diagram, power formula, candidate's modified wiring method, vector diagram, power formula, correct wiring method, vector diagram, power formula, correction factor, examiner's name and date, final score, etc;

Test data analysis function: Based on the data tested at the work site, the computer intelligently provides all possible results of incorrect wiring, and automatically draws phasor diagrams, wiring diagrams, correction factors, and recovery power; Capable of calculating the amount of power to be recovered based on the data tested at the work site;

Automatic alarm function: When the current circuit is open or the voltage is short circuited, the system will alarm, save the alarm record, and automatically enter the safety protection state;

Memory function: The computer can automatically detect the number of alarms for memory voltage and current;

Voice automatic prompt function: used to provide voice prompts for "start, incorrect operation, last 5 minutes, end, etc.";

Automatic wiring check function: It can automatically check whether the wiring on each side of the simulation measuring cabinet has been restored correctly. If the restoration is incorrect, it must provide a possible error prompt;

The function of analyzing the operating status of the meter;

The ability to combine different faults in software and simulate the function of primary and secondary disconnection of high-voltage voltage transformers.

The YBPX-DJF101 three-phase energy meter wiring simulation device intelligently simulates various wiring methods of three-phase three wire and three-phase four wire energy meters through the use of computer mathematical models and logical operations, meeting the requirements of metrological verification, meter installation and connection, electricity inspection, and skill training and assessment for operation personnel in the power sector.
