四、电控柜的安装条件
1、环境条件
1.1、环境温度:要求在-10℃~40℃的范围内,如果环境温度为40℃~50℃,就采取强制通风措施,以利散热;
1.2、相对湿度:在环境温度为40℃时度不超过50%RH,在环境温度为20℃时度不超过90%RH;
1.3、空气条件:空气中不得含有过量尘埃、酸盐、有腐蚀性、导电性、爆炸性气体;
1.4、振动条件:安装在振动小于5.9米/秒2(0.6g)的场所;
1.5、安装倾斜度:电控柜(台)应垂直安装 ,倾斜度不超过5%;
1.6、海拔高度:低于海拔2000米,海拔超过2000米应降额使用.
2、电源条件:
2.1、用户要具有380V/220V三相五相制交流电源,频率50Hz,电压波动≤10%;
2.2、用户供电功率要≥1.5电机功率之和;
2.3、用户供电线路电线电力密度取值要≤2.5 A/1mm2(铜芯线)
五、系统的日常维护
系统在使用过程中要定期进行保养和维护,以保证设备能长期正常和可靠运行.
1、日常检查
1.1、有无异常声音,异常气味。
1.2、电线接头处是否有烧焦或电线破损。
1.3、各接线螺钉有无松动。
1.4、指示灯是否完好。
2、定期检查
2.1、检查各接触器、继电器触点有无烧焦现象。
2.2、各显示、控制仪表是否准确可靠。
2.3、各设备电机和机械结构动作是否正常。
2.4、清扫控制柜内灰尘,清除电器外壳表面尘埃,保持良好的绝缘。
2.5、清扫断路器和接触器灭弧室内壁和栅片上的金属颗粒和黑烟尘。
2.6、各台水泵要轮流使用,否则水泵因长期不用容易锈死。

Four,give or get an electric shock a gearing condition of control the cabinet
1,environment condition
1.1,environment temperature:Request in the - 10 ℃ scopes with 40 s,if environment temperature's ising 40 s is 50 ℃s,adopt compulsorily well ventilated measure,for the convenience of spread hot;
1.2,relative humidity:The degree isn't more than 50% RHs when the environment temperature is 40 ℃ ,degree when the environment temperature is 20 ℃ not more than 90% RHs;
1.3,air condition:Can not imply the surfeit dust,sour salt and have the causticity,electrical conductivity,explosion the air in the air;
1.4,vibrate a condition:Install is vibrate less than 5.9 meters/ per second 2(0.6 gs) places;
1.5,install an inclination degree:The electricity controls a cabinet(set) in response to the perpendicular gearing and tilt to one side a degree not more than 5%;
1.6,elevation height:Low is 2000 meters at the elevation,elevation more than 2000 meters should decline a sum usage.
2,power supply condition:
2.1,the customer have to have a 380 Vs/220 Vs three mutually five mutually make AC power,the frequency 50 Hzs,electric voltage motion ≤ 10%;
2.2,customer the power supply power want ≥ 1.5 electrical engineering powerses with;
2.3,customer the electric wire electric power of the power supply circuit the density take a value to want the ≤ 2.5 As/1 mm 2(copper Xin line)
Five,the daily maintenance of system
The system is in the process of use in want to be periodically carry on maintain to circulate by promising that the equipments can be normal over a long period of time and credibility with maintenance.
