资料介绍

根据民用建筑电动机拖动设备的主要类型.解析电动机全压启动的功率与变压器容量的关系.电动机启动方式选择,星-三角降压启动的原理。电压、电流、导线截面的分析;以国标图集控制原理图为例.介绍如何看懂电动机自动控制原理图,如何设计电动机的主回路和自动控制电路。

Based on the main type of the motor drive equipment for civil building, the relation between power for motor full-voltage starting and transformer capacity, and the motor starting mode, as well as the principle, voltage, current, and conductor cross-section for y- /k voltage-reduced start are analyzed; Taking the control schematic diagram in the Atlas of Electrical National Standards as an example, the way to understand the automatic control schematic diagram of motor, and to design the main circuit and automatic control circuit of motor are introduced
