　　电缆直埋安装时，1-35KV电缆直埋深度不小于0.7m。10KV及以下电缆平行安装时，相互净距不小于0.1m，10-35KV不小于0.25m；交叉安装时距离不小于0.5m。电缆敷设温度不低于0℃，弯曲半径：多芯电缆≥15(D+d)，单芯电缆≥20(D+d)，（D为电缆外径，d为导体外径）。

KA1-2常闭触电断开，使KA2线圈不得电。KA1-3常开闭合，使接触器KM线圈得电，KM-3常开闭合自保。电机启动。，松开按钮SB，看图中各元件动作状况，由于这时接触器KM吸合自保，所以电机连续运行。咱们看图中变化，由于KM吸合，常闭触点KM-1断开，常开触点KM-2闭合。，再次按下SB不松开，由于这时KM-1是断开的，KM-2是闭合的，所以，KA2线圈得电，KA2-1断开，使KA1线圈不能得电。

什么是封锁时间？就是当车辆从厂区内出去时，从光电开关感应到车辆开始，到T2这一时间段内，消毒机不工作，这段时间称之为封锁时间。为了方便说明电路的工作原理，我们来画一下消毒通道、喷雾立柱、感应光电开关的位置等效图，如下图所示。其中小三角代表光电开关，四个小方框代表喷雾立柱。电路的详细工作原理：车辆从大门口进入：光电开关1先感应到车辆，其常开触点闭合，交流接触器KM吸合并自锁，消毒机开始喷雾消毒。因为接触器KM吸合，其常闭触点KM断开，所以光电开关2所在的支路电源被断开，因此中间继电器KA不会吸合，自然也不会影响光电开关1所在的支路。

　　A类阻燃性能优于C类阻燃性能。使用特点额定电压U0/U为450/750V。电缆导体的长期允许工作温度为70℃。电缆的敷设温度不低于0℃。推荐的允许弯曲半径无铠装层的电缆，应不小于电缆外径的6倍。有铠装、铜带屏蔽结构的电缆，应不小于电缆外径的12倍。



RS485 cable transmission distance: 24 awg RS - 485 cable (wire diameter of 0.51 mm), for example, when the data rate to below 90 kbit/S, assuming that allow loss of 6 DBV, the cable length is 1200 m, when the data rate of 600 kbit/S, using 24 awg cable, cable length is 200 m, if using 19 awg cable (wire diameter of 0.91 mm) cable degrees will be able to more than 200 m long; If 28AWG cable is used (line diameter is 0.32mm), the cable length can only be less than 200m.
