Abstract

An electrical practice training device comprises a power source, a controller, a sampling unit, a driving unit, a three-phase alternating-current input, a contactor, an on-off control unit, a practice training unit, a terminal strip, a practice training circuit connecting line, a communication interface, a computer and an indication element. By means of different wiring schemes, inching and self-locking control and positive and reverse rotation control of three-phase asynchronous motors can be completed, and start and stop sequence control, pole-changing speed control, remote and local control, plug braking control and dynamic braking control of the two motors are completed, so that convenience is brought to electrical practice training, and hand operation capability of students can be improved.

Description

technical field [0001] The invention relates to a teaching and training device, in particular to an electrical training device for students majoring in mechatronics and electrical automation in vocational colleges, and belongs to the field of electrical technology. Background technique [0002] Higher vocational colleges aim at cultivating practical, technical and skilled professionals who have certain theoretical knowledge and strong practical ability, and are oriented to grassroots, production, service and management front-line professional positions. Applied talents of high technology should enable students to have the necessary theoretical knowledge and scientific and cultural foundation, master the main technology proficiently, focus on practical application, and focus on the comprehensive application of relevant knowledge. In order to cultivate the hands-on ability of students in higher vocational colleges, combined with the courses they have learned, the school needs ...
