附件附件中有完整图文描述~~~~~ 加热管 温控器设计 单相机器，带plug，也不是全极断开。 如图， 1. 我们的机器用一个EGO的毛细管温控器加在加热管的一端非正常测试做干烧时，可以满足19.4和19.5的要求吗？ 2. 如果不可以的话，我们EGO有3 poles的型号，我将2极接在加热管的两端可以满足吗？
8 E, e/ i- i5 i; I- S三相器具，固定接线，不带插头；开关控制接触器可以全极断开 如图 一个EGO，有3poles，分别接到三根加热管的一端。 这样应该可以避开19.5的测试，但是19.4的可以满足吗？ 如果不行，可以采取什么样的方法来解决这个问题？ . W! S/ {* J% S+ l6 V
