为了弥补国内电动机保护器行业没有完全模块式产品的空白,给出一种模块式电动机保护器ARD3T的主体、测量模块设计方法.按照功能进行模块划分,各模块利用内部数据总线进行数据传输,通过内部总线进行模块供电.给出主体、测量模块设计方法,典型硬件原理图,指出设计中所要注意的事项.给出各种环境下的测试数据,最后进一步给出了产品采用的抗干扰处理措施,测试结果表明设计的正确性和合理性,产品的设计思想、设计理念更符合未来市场的需求.%To full in the gap that the domestic motor protector industry has not fully modular products, this paper gives the main body and measurement module design method of ARD3T motor protector. ARD3T consists of several modules, which are divided according to the product function. Each module uses internal data bus ro ralize data transmission and power supply. Design methods and typical hardware schematics of the main body and measurement module are proposed, and the precautions in the design are pointed out. Test data under various environments are given, and anti-jamming measures used by the product are provided further at the end of this paper. The test results show the correctness and rationality of the design method. The design concept is more in line with the future needs of the market.
