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? ) Y/ @% X9 q7 Z7 `7 Q2 U
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? @4 i9 `. \- b: N4 L
