The inverter is widely used in the starting and speed regulation system of AC motors. It has the advantages of small starting current, smooth speed regulation, large speed -specific ratio, stable operation, and energy saving. Metallurgical industry, various fan, water pump, lifting machinery, production machinery and many other fields. "Three -phase asynchronous motor inverter starting and speed adjustment tr--ning cabinet" is to meet the needs of the installation, commissioning, and m--ntenance of motor startup and speed regulation equipment in various industries in the society. Combining electrical electrical categories of vocational colleges and universities "Electrician Technology", "Motor Drag and Control", "Inverter Speed Regulation Technology", "Electrical Control Technology" and other courses were developed by related majors. The tr--ning and assessment equipment of relevant units such as (He) and other related units is also a tr--ning equipment for electrical related majors in vocational colleges.

2. Features

1. The standard power distribution cabinet is used as the m--n cabinet, which controls the use of reasonable, small area, and beautiful appearance.

2. Control cabinet's device selection, installation, wiring and other strict accordance with the "electrical equipment safety design guidance", "insulation coordination of equipment in the low -voltage system", "the color of the wire in the set set of electronics" Design of relevant national standards such as rotation direction ". The devices used are well -known brands at home and abroad, and the quality of the product is guaranteed.

3. Using industrial inverters, and the YPF series inverter speed adjustment three -phase asynchronous motor as the control object, close to the industrial scene.

4. Provide various protection functions, which are safe and reliable in tr--ning.

3. Technical performance

1. Input voltage: three -phase and four lines (or three -phase and five lines) ~ 380V ± 10%50Hz

2. Working environment: temperature -5 ℃ ～+40 ℃ relative humidity <85%(25 ℃) altitude <2000M

3. Device capacity: <4KVA

Fourth, system equipment

The real tr--ning cabinet is m--nly composed of cabinets, electrical rooms, general inverters, signal sources, and three -phase asynchronous motors of the three -phase electrical motor.

1. Cabinet

The cabinet is a double -layer sub -light -densely pattern spraying structure, double -sided cabinet door design, cold -rolled steel plate, strong and strong. There is an in -line terminal, out -of -line holes, and grounding signs in the interior. The control cabinet also has four universal wheels and four fixed adjustment mechanisms.
