在农业排灌、农副产品加工等作业中,如果电路发生漏电故障,不仅浪费能源,增加农业排灌、农副产品加工的成本,而且很不安全,易造成人身伤亡和火灾事故.因此,一旦电路发生漏电故障,工作人员必须及时进行检查和维修.1.电路漏电故障的现象电路发生漏电故障后,主要表现为用电度数比正常时高、建筑物带电、电动机发热等. In the agricultural irrigation and drainage, agricultural and sideline products processing and other operations, if the circuit leakage fault occurs, not only a waste of energy, increase agricultural irrigation and drainage, agricultural and sideline products processing costs, but also very unsafe, easy to cause personal injury and fire accidents. Failure, the staff must be timely inspection and maintenance .1 circuit leakage fault phenomenon circuit leakage fault occurs, the main performance for the electricity than the normal high, building charged, motor fever and so on.
