BeditionMainly for troubleshooting and installing meters and power on training cabinets. Installation, wiring, and debugging of different collection networking methods between concentrators, collectors, and energy meters, as well as installation, wiring, and debugging of the total leakage protection circuit breaker in the substation area. Troubleshooting of electricity information collection, line loss analysis, leakage fault investigation, etc.

II Functional Features

device configuration3A single-phase voltage regulator that can adjust different output voltages as needed, with a range of adjustment0V-250VThe output voltage can be monitored based on the digital voltmeter configured by the device.

device configuration3A current adjustment rotation can be used to adjust different output currents according to needs, with a current adjustment range of1A,1.5A.2.5AThe output current can be monitored based on the digital ammeter configured by the device.

AeditionMain functions:

1) Suitable for training, technical assessment, and technical appraisal of low-voltage single and three-phase metering user meter wiring process;

2) Suitable for training, technical assessment, and technical appraisal on the wiring process of replacing three-phase four wire energy meters with three single-phase meters;

3) Suitable for training, technical assessment, and technical appraisal of the wiring process of Y - △ starting control circuit for three-phase asynchronous motors;

4) Suitable for training, technical assessment, and technical appraisal of the wiring process for the forward and reverse starting control circuit of three-phase asynchronous motors;

5) Suitable for training, technical assessment, and technical appraisal of single-phase residential lighting circuit wiring process;

6) Suitable for wiring process training, technical assessment, and technical appraisal of the inching and self-locking control circuits of three-phase asynchronous motors;

7) Suitable for installation training of PLC controlled three-phase motor starting control circuit;

8) The device can meet the installation training of concentrators, collectors, and energy meters, and can also meet the communication wiring training between the three, including carrier communication and RS485 communication wiring.

BeditionMain functions:

1) In order to avoid short circuits caused by improper operation by students, all circuits of the cabinet are now connected according to the on-site wiring method. In principle, students are not allowed to perform wiring operations on the meter and general protection parts. When conducting the meter installation and power connection training project on side B, it is necessary to replace the operation panel module on side B;

2) The fault simulation module is suitable for demonstrating the faults of power leakage protection devices. It can set a leakage current of 0-250mA and a fineness of 1mA to meet the tripping simulation of various types of total leakage protection devices. It enables students to master the debugging and testing of leakage protection devices, and to judge and troubleshoot leakage faults;

3) Can simulate the fault phenomenon of the total leakage protector tripping due to the damage and refusal to trip of the three-phase user leakage switch;

4) Can simulate the fault phenomenon of the total leakage protector tripping due to the damage and refusal to trip of the single-phase user leakage switch;

5) It can simulate the fault phenomenon of the main leakage protector tripping due to the zero line crossing of the main leakage protector;

6) Can simulate power supply faults such as phase failure and phase loss in the main protection incoming line;

7) It can simulate the phenomenon where the current of the user meter in the substation area is less than the total current of the substation area due to line loss;

8) Can achieve common on-site faults such as voltage phase failure and current short circuit in three-phase energy meters;

9) It can achieve common faults such as single-phase energy meter diversion, electricity theft, and abnormal power consumption of one fire and one ground;

10) It can simulate common faults such as terminal voltage phase failure, current short circuit, and reverse polarity of current;

11) Can simulate common faults such as RS485 disconnection A, disconnection B, and A/B reversal between the collector and the energy meter;

12) The set fault can be manually restored through the configured fault recovery line.
