2021 Good Quality Auto Repair Professional Teaching Equipment - Comprehensive training device for microcomputer protection of power system – Zhiyang Beifang

Comprehensive training device for microcomputer protection of power system

Type: BF-HYDLS-02A

1. Rated voltage: three-phase five-wire～380V±10% 50Hz

2. Working environment: the ambient temperature range is -5℃～+40℃, relative humidity＜85% (25℃), altitude＜4000m

3. Rated capacity: 3.0kVA

4. Dimensions: 1240mm×500mm×2000mm

Feature

1. The core equipment of the training device-microcomputer line measurement and control device, microcomputer transformer measurement and control device, and a physical simulation primary system, so that students can intuitively understand the changes in power parameters when various short-circuit faults occur in the power system.

The training device has an upgrade interface, and users can expand the relay protection and secondary circuit training projects based on the simulated primary system.
2. Communication network: The training device has an RS-485 bus interface, which can realize the power system SCADA based on the microcomputer measurement and control device.

3. Laboratory remote management system software (in order to avoid intellectual property disputes, the bidding site needs to provide computer software copyright certificates and demonstration videos)

The system integrates the remote laboratory bench power management system, and monitors the power switch status of the student laboratory bench through mobile phone or other mobile terminal system monitoring; individually turns on and off the student laboratory bench power supply; fully turns on or all off the laboratory bench power supply function; regularly turns on and off the power supply function .
