General electrician training assessment device

The electrician training and assessment device is in accordance with the content requirements of "Worker Technical Grade Standards" and "Professional Skill Appraisal Standards" issued by the Ministry of Labor and Social Security. A new generation of training, theoretical verification, and practical ability designed based on the actual situation of electrician training assessment. Appraisal and identification in one multifunctional device. The entire equipment. The entire equipment is based on a standard power distribution cabinet, which makes reasonable use of the double-sided space of the cabinet. Scientifically arrange electrical appliances and supporting experimental equipment. It can meet the practical operation items of electric drag control and lighting circuit in electrician assessment and appraisal. Proven by Shenzhen Skills Training Appraisal Center many times. The cabinet is reasonably designed. Convenient operation. One cabinet is multi-purpose, and all electrical contacts have been connected to the large terminal block. Therefore reduce material consumption. Extended service life. This set of equipment is suitable for all labor occupation skills appraisal departments, and at the same time it is suitable for electricians in major technical schools, technical schools, and vocational schools. The teaching and experiment of electric drag. ( Teaching Equipment | Teaching Instruments )
The structure and electrical configuration technology training cabinet is designed and manufactured according to the standard electrical control cabinet (specification: 700x450x1 700mm). It uses a double-sided space position, and the cabinet is equipped with a single electromechanical meter required to complete various lighting circuits. Fluorescent lamp, incandescent lamp, single switch, double switch. Socket, etc. And all kinds of low-voltage electrical appliances needed for electrical control, such as earth leakage circuit breakers, fuses, travel switches. Contactor, time switch. Voltmeters, ammeters and electricity meters. In order to extend the service life of the circuit, the contacts of all electrical appliances are first connected to the terminal block, and then students are connected to the terminal block for durability. The training cabinet is also equipped with two auxiliary motors. Various experiments can be performed with this motor support.
