程控数字交换机电源系统的特殊性以及在安装设计中的考虑

Power Supply of Program Controlled Digital Exchanger-Specification and Installation Consideration

本文根据程控交换机的数字电路工作速度高及各种集成块均为敏感性元件的特点,从供电体制、配电方式及所需直流总功率三个方面比较程控数字交换机与机电制交换机对电源系统的要求,并对其安装设计中的问题加以探讨。此外,还对铅蓄电池的性能要求、设计选型中应考虑的问题提出了看法。

Consideration is given to the high-speed and sensitive integrated circuit module of program controlled digital exchanger. The comparisons are made of the requisites of power source in terms of power distribution available,feeding system,main features and total power for the program controlled digital exchanger and electro-mechanical exchanger. The installation consideration is presented. Additionally performance specification and design features of lead batteries required are discussed.
