JG-104B mesh-type electrician, electronic skills and process training assessment device
JG-104B mesh-type electrical and electronic skills and process training assessment device :
JG-104C mesh-type electrician skills and process training assessment device (double-sided, four-group type): ( teaching equipment | teaching instrument )
I. Overview: The training device is mainly composed of training table, component storage cabinet, and mesh plate. Operators arrange, install, and route components and components according to the training lines, and approach industrial sites, which is conducive to training students' practical ability and operation skills. The training project can be determined by itself, and the corresponding components are selected according to the selected project. It is an ideal assessment equipment for students' training and electrician certification in colleges, vocational schools, technical and training institutions. Second, characteristics: 1. Electrical control circuit components are installed on the mesh plate, easy to operate, flexible, fast replacement, easy to expand functions or carry out new training projects. 2. The operation console can be put into use with only three-phase four-wire AC power, with a small footprint, saving space and reducing management staff and infrastructure investment. 3. It is equipped with a voltage-type current-type leakage protector, and a single-chip microcomputer automatically monitors the training device for overload or short-circuit. Once it occurs, it can automatically cut off the power. After troubleshooting, the working power can be restarted. To ensure the safety of facilities and operators. Each power output has a monitoring function, and each measuring instrument also has a reliable protection function. 4. The training platform is of four groups, each station is equipped with independent electrician instrument and power supply, and the four stations are trained simultaneously without interference. 3. Technical performance: 1. Working power: Three-phase four-wire (or three-phase five-wire) ~ 380V ± 5% 50Hz 2. Temperature: -10 ℃ ~ 40 ℃, relative humidity <85% (25 ℃) 3. Device Capacity: <1.5KVA 4. Weight: 200Kg 5. Dimensions: 1500mm × 1400mm × 1700mm 4. Training equipment 1.Each side is equipped with start, stop and emergency stop functions. The single-chip computer monitors the overload and short-circuit function of the training platform throughout the whole process. When there is a situation, it can automatically cut off the working power. After the fault is reset, the power can be restarted to ensure the safety of the equipment and the operator. 2. Each station is provided with a main power switch with leakage protection function. When the leakage current reaches 30mA, the protection device will act. 3. Provide single-phase and three-phase sockets for each group. 4. One DC stabilized power supply for each station: voltage 0-30V, current 3A, built-in relay automatic shifting, multi-turn potentiometer continuous adjustment, easy to use, and indicated by digital meter. Voltage stability <10 -2, load stability <10 -2, ripple voltage <5Mv. 5. Each station is equipped with 3 AC 5A ammeters with accuracy of 1.5. 6.Each station is equipped with intelligent power and power factor. Table 1 is only designed by a 24-bit dedicated DSP, a 16-bit high-precision AD converter and a high-speed MPU unit. The key-control and digital display windows are used to realize the man-machine dialogue function control mode . The software adopts RTOS design ideas, and is equipped with PC monitoring software to strengthen analysis capabilities. Can measure the power and power factor of the circuit. The power measurement accuracy is 1.0, the power factor measurement range is 0.3-1.0, the voltage and current ranges are 450V and 5A, and the load can be automatically determined (inductive display "L", capacitive display "C", pure resistance is not displayed), and Store measurement data for review at any time. 7, training table: iron double-layer matte dense grain spray structure, desktop is fire-resistant, waterproof, wear-resistant high-density board, and equipped with component storage cabinets and drawers.
