吊冰用行车及电动葫芦是冷库制冰车间关键设备之一,行车和电动葫芦安全运行与否,直接关系到制冰车间的产量。我冷库制冰车间行车及电动葫芦的控制线路原采用380V电源:塑壳控制按钮采用上海第一开关厂产品,LA100—6型,其产品说明书“使用范围在额定电压36V,额定控制容量100VA”。但安装至今经多年使用,操作人员在操作按钮时,常常发现按钮严重麻电现象,特别是南方沿海地区有霉雨季节,整台行车都有严重带电情况。行车操作人员为防止触电人身事故,就想办法将按钮用透明塑料袋包缠,严重潮湿时
Hanging ice driving and electric hoist refrigeration plant is one of the key equipment, driving and electric hoist safe operation or not, directly related to the production of ice workshop. I cold storage ice shop and electric hoist control circuit used the original 380V power supply: plastic shell control switch using the first switch plant in Shanghai, LA100-6 type, the product manual “use of the rated voltage of 36V, rated control capacity of 100VA” . However, since the installation has been used for many years, operators often find the buttons are severely tampered with while operating the buttons. In particular, there are moldy rainy seasons in the southern coastal areas, and the entire vehicle has serious electrification. Driving operators to prevent electric shock personal accident, think of a way to button wrapped in transparent plastic bags, severe wet
