单片机数字油流继电器的设计与标定

The Design and Standardization of the Digital Oil Flowing Relay Controlled by Monolithic Computer

油流继电器是大型电力变压器冷却循环系统的重要部件。目前采用的油流继电器多为机械档板式,由于测量精度低,且不能与主控制室进行通讯,急待更新换代。为此研究设计了单片机数字油流计电器。本文介绍了其工作原理。

The oil flowing relay is the important prot of the cooling system of power transformer.At the moment,the mechanic oil flowing relay is mostly used with lower accuracy and no communication with control-room.It is necessary that the digital oil flowing relay be controlled by monolithic computer instead of the mechanic one.In this poper,the principle and the design method as well as the standardization of the digital oil flowing relay were introduced.
