潜水泵的电动机与泵体联接成一体,抽水时全部浸在水里。如果绝缘不良,就会漏电。去年我县有位青年,因抗旱用潜水泵抽水,未先切断电源就下水检查水泵,因漏电造成了触电事故。这个教训应深切记取。为了做到潜水泵的安全使用,要做到下面几点: 1.使用前应该用500伏摇表摇测,要求电动机的绝缘不应小于0.5兆欧。如果电源距水泵使用地点较远,电缆的截面应选择大一号的,以防电压降得太大。电缆接头尽可能减少,若用两根电缆延长接线,要用插座连接,如一时急用又无插头和插座,要用绝缘胶布包扎好,并做好危险标记,决不能在接头处只包扎绝缘带或黑胶布,就抛在河塘 Submersible pump motor connected with the pump body into one, all immersed in water pumping. If the insulation is poor, it will leak. Last year, a young man in my county, due to drought with the submersible pump, did not cut off the power before the water pump, due to leakage caused by electric shock. This lesson should be deeply remembered. In order to achieve the safe use of submersible pumps, to achieve the following points: 1 should be used before 500 V shake shake test, the motor insulation requirements should not be less than 0.5 megohm. If the power supply is far away from the pump, the cross-section of the cable should be chosen as larger one to prevent the voltage from dropping too much. Cable joints as much as possible, if the two cables to extend the connection, to use the socket connection, such as a temporary emergency with no plug and socket, to be wrapped with insulating tape, and do a good job of marking the danger, Or vinyl tape, throw in the river pond
