1.前言随着自动检测技术的发展,各种自动转换电路被广泛地应用,但是在仪器的检测电路中执行机构所需的容量增加了,所以人们对自动转换电路的要求就更高了。我们在设计一台用于东风型内燃机车上的“电压调整器故障检测仪”中的32位自动转换电路时,根据执行机构的需要,选择了几种 1. Introduction With the development of automatic detection technology, a variety of automatic conversion circuits are widely used, but in the detection circuit of the instrument, the required capacity of the actuator is increased, so people are more demanding of automatic conversion circuits. When we designed a 32-bit automatic conversion circuit in the “voltage regulator fault detector” for a DFG diesel locomotive, several types of actuators were selected according to the need of the actuator
