I Product overview

the installation and commissioning training device of modern electrical control system is a product developed according to the requirements of the Ministry of education "revitalization of the 21st century vocational education curriculum reform and textbook construction planning", combined with the actual production and the skill requirements of vocational posts, and in accordance with the teaching and training requirements of vocational schools. The training and assessment equipment is suitable for the installation and maintenance of electromechanical equipment, the application of electromechanical technology, electrical operation and control, the application of electrical technology and the application and maintenance of electronic and electrical appliances in higher vocational schools and secondary vocational schools, as well as non electrical majors such as electrotechnics, basic skills of electrotechnics, Electrotechnical measurement and instrumentation, motor and electrical control, motor control circuit "Electric drive control circuit" and other related professional modules of vocational ability teaching and training

II. Structural composition

as the advanced training of maintenance electricians involves a wide range of professional contents and great technological leap forward, the existing equipment for teaching, training and assessment of maintenance electricians adopts a variety of special equipment combination assessment forms, (for example, power electronic examination equipment, machine tool electrical examination equipment, PLC equipment, etc., have large investment costs, many professional training and examination points, inconvenient to use, long examination preparation time, occupy many examination Resources, and are not conducive to the use of the environment with limited floor area.

the equipment takes the standard power distribution cabinet as the main cabinet, makes reasonable use of the double-sided space of the cabinet body, and scientifically arranges electrical appliances and supporting experimental equipment. The purpose of this utility model is to Overcome the shortcomings of the above existing technologies, and provide an innovative technical scheme with small floor area, reasonable layout, compact structure, complete functions and improved assessment efficiency

this kind of maintenance electrician teaching cabinet type practical training and assessment device consists of a cabinet frame, an observation window, an instrument operation panel, an electrical system, and a motor unit. The said electrical system consists of a number of parts arranged longitudinally on the front and rear panels, including the touch screen part, the PLC host part, the frequency converter part, the power electronics part, the DC power supply part, Zheng 1ren, etc. using hydrogel (poly (b hydroxyethyl methacrylate HEMA) as the material, The hydrogel soft prosthesis consists of electric drive and relay control part, motor shaft power, torque, speed measurement part, AC and DC voltage, current, single and three-phase AC energy, AC power, power factor measurement part, etc

the panel is equipped with operation buttons, and various low-voltage electrical appliances required to complete the motor control circuit are installed inside, such as leakage circuit breaker, fuse, current transformer, contactor, intermediate relay, thermal relay, travel switch button, transfer switch, voltmeter, ammeter, watt hour meter, etc. in order to prolong the service life of electrical appliances, the contacts of each electrical appliance are connected to the terminal first, and then connected on the terminal for operation, For durability

it is designed according to the electrical control cabinet on the production site, and the components are equipped according to the control circuit commonly used in production practice. The selected components are the same as the components actually used in production and life, creating a working situation, and the practical training is the same as the actual working process of production. The skill training obtained is comprehensive, and the professional knowledge and skills mastered are solid, which has a good training effect on students' professional ability

it is equipped with leakage protection, overload and circuit protection to ensure personal safety and equipment use safety. It has been proved by the practice of the appraisal center for many times that it is an ideal vocational education training equipment
