在高温持久蠕变试验中,为要得到一个正确的性能数据,温度只允许在一个很狭窄的范围内变动。因此,高温持久蠕变试验要求高精度的温度控制调节设备。本文主要介绍在高温持久蠕变试验中,采用上海自动化仪表六厂生产的DWT-702温度自动控制器的粗浅认识,供大家参考。点是要求可控硅的反向耐压在600伏特以上,而且串并联的方式本身就要消耗一定的功率. DVVT一702通魔控制.简介该控制器由毫伏定值器、微伏放大器、P.1.D.调节器和可控硅触发器等部分组成(图1).高温炉炉脸
In a high-temperature, long-lasting creep test, the temperature is only allowed to vary within a very narrow range in order to obtain a correct performance data. Therefore, high-temperature creep test requires high-precision temperature control equipment. This article mainly introduces the superficial understanding of the DWT-702 temperature automatic controller produced by Shanghai Automation Instrumentation No. 6 Plant for long-term creep test at high temperature for your reference. The point is to require SCR reverse voltage withstand above 600 volts, and the series-parallel manner itself consumes a certain amount of power. DVVT a 702-pass control. Introduction The controller consists of millivolt value, microvolt amplifier , P.1.D regulator and thyristor trigger and other components (Figure 1). High-temperature furnace face
