1. Product Overview:
MYN-16A Electrician Skills Training Device is developed according to the Vocational Skills Appraisal Center of the Ministry of Labor and Social Security for the vocational training and skill appraisal of electricians, and is developed in combination with the practical application and development of industry. The electrician skills experimental equipment is suitable for the training and teaching of large and medium-sized colleges and secondary vocational schools, and can also be used as the training and qualification equipment for electrician technicians by enterprises and relevant electrician training and appraisal departments. The equipment is mainly composed of a laboratory table and a mesh board hanging box, and the layout, installation and wiring of the components are all completed by the students themselves, which is conducive to cultivating students' hands-on ability and operation skills.
IIStructural features:This training platform is composed of three parts: the training screen (built-in power supply), the training table, and the training locker. 1. 30mm 60mm forming aluminum profile is used as the main frame material of the equipment; The key parts are connected with triangular ribs reinforced with hexagon screws; It is composed of two 30mm 30mm aluminum alloy profiles and chutes to form a mesh plate fixing mechanism; Below the fixed mechanism is an iron double-station power box, and the layout of each station power box is a power supply protection device, a power supply indication device, and a power supply output in turn; 2. The top of the training table is specially made of 25mm hemp gray high-density laminate edge banding, which effectively improves the insulation level; At least 4 guide wheels are installed at the bottom of the experimental table to facilitate the movement of the training bench; 3. Mesh plate: It is finished by CNC punch, and the mesh distribution is reasonable and uniform. The aperture is unified, and the gas parts that can be installed on it include all kinds of low-voltage electrical. The thickness of the mesh plate is 15mm, size 774*580mm3. Technical indicators:1. Appearance: overall size: 1632mm 700mm 1638mm; 2. The material of the training bench: steel plate, aluminum alloy structure; 3. Power supply: 1) Input: three-phase AC 380V 10% 50Hz three-phase five-wire; 2) Fixed AC output: 2 groups of three-phase five-wire 380V plug-in type, 2 groups of 220V plug-in type. 4. Rectifier diode: Provide four rectifier diodes 1N5408 for energy consumption braking circuit. 5. Adjustable DC output: 0 24V 2A continuously adjustable 2 groups (with pointer voltage, pointer ammeter to monitor power supply changes in real time); 6. Three 75 75W power resistors are provided for various specifications of resistors, which are used for step-down start-up circuits. Provide one of 10 25W power resistors for energy consumption braking circuits. 7. Interface and instrument: 2 pointer voltmeters, monitor the voltage change of the power grid at all times; 8. Protection: The fuse is short-circuit protected, the circuit breaker has overload protection, the leakage switch has the function of leakage protection, and the leakage protection action current is 30mA.
