|NT828安装注意事项(Installation precautions)
探测器电源线不小于2x 1.5mm.以上线路检查完毕并确认布线满足要求后,首先将模块通电,等待传感器稳定,报警器进行信号采集后,进行模块回路信息设置,额定报警值设置,对模块的各项功能进行测试;  配线应整齐,避免交叉,并应固定牢靠;    

 

|NT828试验设备(Test equipment)
每一个设备出厂前都会经过一整套完整的试验流程以保证它的品质:
--Step 1--静电放电发生器
--Step 2--多功能抗干扰测试
--Step 3--可程式恒温湿试验机
--Step 4--老温老化房
--Step 5--初校验台
--Step 6--复校验台
--Step 7--电能走字台

 Every equipment will go through a complete set of test process before leing the factory to ensure its quality
--Step 1 -- electrostatic discharge generator

 |NT828相关电工知识(Relevant electrical knowledge)

  各个省的用电分时划分,虽然有些不同。但大同小异下面就以安徽省为例说明(一)居民生活用电:一般情况下,居民生活用电的划分,划分为两个时段:(1)平时段;一共14个小时;即上午08:00点到晚间22:00点。  电流强度越大越容易致命;持续时间越长越可能死亡。对不同强度电流的反应大致如下:8-10mA:手主动摆脱电极已有困难,指关节有剧痛感。20-25mA:手迅速麻痹...触电的致命因素及触电致死的原因触电以后致死的*主要的原因是心室纤颤。  所以,应选用同等或大一号截面的铜导线与刀闸连接,然后铝导线再与铜导线连接,连接长度不小于铝导线直径的10倍,*用粘性胶带缠绕绝缘。经过以上的安装处理,闸刀的使用寿命可比原来提高2~4倍。作者单位:河北省宁晋县电力局配变C相为什么易烧毁吴业勇每年都有很多的配变被烧坏,其中C相烧坏的比例很大。
