Elevator electrical control training device

1. The model elevator has 4 floors and 4 stations. It consists of analogytic road frame, car, p--r, dictation machine, elevator door, door motor, out -of -floor call box, and m--n safety devices. The fixed setting is set on the side of the experimental table. The internal demand of analogyard frame is configured to detect floor sensors, flat layers (similar to actual elevators), etc. Its wiring terminals are cited to the inserted holes of the simulated manhole frame. The manhole frame uses metal materials as the m--n bracket, and organic glass is closed.

The device adopts a desktop structure, and the active drawer electrical board is set. Each layer drawer board is equipped with a public wiring board (bus -type wiring method, the number of bus connection points must reach 120 points), and the industrial tank ch--n connection is used between the drawer electrical board. The drawer panel connection uses a real elevator multi -core accompanying cable.

2. Model elevator drag system

The model elevator drag system is fixed on the experimental table, consisting of three -phase AC motors, reducers, fuses, heating relays, phase sequences and disconnecting relays, and AC contactors used for positive and reverse control. 380V.

3. Elevator door control system

The elevator door control system consists of the switching door control circuit and door speed adjustment circuit. The door motor is fixed on the analog manhole frame, and the DC 24V is powered. Control in relay and use independent hanging boards, which can achieve manual or automatic control of the door.

1. The characteristics of the product:

 

The experimental table has more comprehensive safety protection measures and more complete functions. The center of the experimental table is equipped with a universal circuit board, and the circuit board is injected into injection. The surface cloth has porous into a set of connecting jacks. The component box is freely inserted into an experimental circuit. The intuitiveness is good. Component symbols, clear and beautiful lines. The box body and the lid adopt a more scientific card structure, which is convenient for m--ntenance and disassembly. The components are placed in the left and right cabinets under the experimental table, which greatly improves the level of management and the degree of planning, which greatly reduces the preparation of teachers' experiment.
