电机变频调速就地控制箱的改进方法及结构

Improvement method and structure of variable frequency speed regulation local control box of motor

Abstract

The invention discloses an improvement method and a device of a variable frequency speed regulation local control box of a motor. The method comprises the step of additionally arranging a selective switch and a rotary potentiometer on the local control box, wherein the selective switch is used for selecting a speed regulation position, namely selecting remote speed regulation or local speed regulation. The method makes full use of a use function of a standard interface of a frequency converter, and a local speed regulation controller is provided. According to the method, remote or local speed regulation control can be selected on site, so that speed regulation control is more flexible, and the method is applicable to all occasions with frequency converter use in a plant. The method can be realized by hardly increasing investment, has considerable flexibility and economy, and plays popularization significance.
本发明公开了一种电机变频调速就地控制箱的改进方法及装置。该方法是在就地控制箱上增设了一个选择开关和一个旋转电位器。新增选择开关为调速位置选择,即选择远程调速或选择本地调速;本发明充分利用了变频器标准接口的使用功能,提供一个本地调速的控制器。本发明可以在现场选择采用远程或本地进行调速控制,使调速控制更加灵活,适用于工厂中所有使用变频器的场合。本发明几乎不用增加什么投资就可以实现,具有相当的灵活性、经济性,有值得推广的意义。
