  有的交流双束电梯采用继电器控制,器件多,控制结构复杂,接触式触点可靠性差。 Some interchange twin bunchs of elevators and adopt the RC , and the component are much , and the control structure is complex , and the contact style tip dependability is bad 。
   交流调速电梯早期大多数是分立元件控制。 The exchange shifts the rapid elevator early phase bulk are that the discrete component is dominateeed 。
   许多原器件，例如可控硅的原器件，当时的技术不好，制造质量不稳定。 Much original component ，For instance original component of silicon controlled rectifier ，The technique at that time is not good ，The tabrication quality is not steadyd 。
   当时制造的直流电的调速电梯基本上是发电机拖动，使用噪音大。 The rapid elevator of the direct current manufacture at that time accent is that the dynamo drags haul essentially ，The use noise is greatly 。
   机械式选层器由于磨擦，容易导致触头磨损而出现接触不良。 The mechanical type chooses the tier utensil thanks to the rub ，Cause easily the contact finger to wear and tear and has ariseed loose contact 。
   分立元件在继电器的控制下，故障率很高 The discrete component is living , and relay control is geted off ，Therefore block leading is very tall 。
