我校于90年根据现有设备,因陋就简,修旧利废,自己动手改造现有电源.实现了电源的直接供电。经过几年实践证明,这种供电方法简易可行,使用安全可靠、方便、实用,又便于维修,受到上课师生的欢迎,为此,特向读者介绍这方面做法,以供参考。具体做法如下:一、地面敷线设计图(以24组为例) 说明:1、粗线为高压敷线,橡套或塑套导线载≥20A。2、细线为低压敷线,橡套或塑套导线载
Our school in 90 years based on existing equipment, due to simple, repair old waste, do it yourself transform the existing power supply to achieve a direct power supply. After several years of practice proved that this power supply method is simple and feasible, the use of safe and reliable, convenient, practical, and easy maintenance, teachers and students welcomed by the class, for which, especially for readers to introduce this approach for reference. Specific practices are as follows: First, the design of the ground wire layout (24 groups as an example) Description: 1, the thick line for the high voltage wiring, rubber or plastic sheath wire load ≥ 20A. 2, thin line for the low-voltage wiring, rubber or plastic sets of wire load
