JGFT -7900L escalator teaching assessment training device

Product Features

1. Overview:

Elevator electrical skill training assessment test device is used for PLC electrical control teaching and assessment of various majors, technical secondary schools, vocational schools in electrical, automation and related majors, social electrician training, and counties and cities maintenance electrician identification stations (stations) The research and development can be used for classroom demonstration, elevator electrical control principle operation and experimental practice. The training device has set up dozens of circuit faults artificially and concealed. Students can analyze and judge the faults with the help of schematic diagrams, and comprehensively and truly understand the electrical faults of the elevator.

2. Basic configuration of the experimental device

1. AC power supply: provide three-phase five-wire AC power (AC380V) with overcurrent leakage protection measures.

2. Personal safety protection body system: The current-type leakage protection device is installed on the experiment table. If there is leakage in the control circuit or the strong current output circuit, immediately cut off the power to ensure the safety of laboratory personnel and equipment.

3. Experimental bench: There are voltage and current monitoring meters installed on the panel, which can observe the working status of the elevator intuitively in real time, and the elevator shape is realistic; it is completely developed by the elevator that is actually used in industry. The elevator is equipped with a complete and detailed line schematic diagram, which is convenient for analyzing the working principle of the equipment and analyzing and troubleshooting line faults.

4. Fault setting: The panel is equipped with fault switches ranging from 20-28 according to different configurations, and 29-32 are spare switches. It is convenient to randomly set elevator safety line faults during the teaching process and fully meet the needs of changing teaching content.

5. Experimental table: The experimental table is constructed of industrial standard aluminum profiles, and the surface of the profiles is treated with electrical oxidation, which is beautiful and durable. The table top is made of high-density sheet material, which has a solid structure and a beautiful appearance. There are two large drawers for tools and materials.

3. Experimental items and main contents:

1. Familiarize students with the working principle and structural composition of common sidewalk escalators in industry, and the structure and principle of low-voltage electrical appliances.

2. By analyzing the electrical schematic diagram, students can master the safety protection and working form of the elevator through the analysis of the schematic diagram; through analysis and measurement, find out the location of the fault point and deeply understand the operation principle of the elevator.

3, to improve students' practical hands-on analysis ability, and practically improve their skill operation level.

4. Through the analysis and elimination of elevator faults, complete the recognition and understanding of common elevator faults.

5. Through programming the Mitsubishi PLC host, understand the programming principles and methods of the PLC program.

4. Structural characteristics of escalator

1. Structural characteristics

The escalator is an open transportation machine that is driven by electricity and can carry a large number of passengers continuously in a certain direction.

It has the characteristics of compact structure, safety and reliability, simple and convenient installation and maintenance. Therefore, in places with large and concentrated passenger traffic,

Such as stations, docks, shopping malls, etc., are widely used. The escalator has transportation capacity, and all transmission parts are made of metal parts.
