摘要
电能作为一种特殊的商品具有生产与使用同时进行和无实物可见的特性。为使电能在流通环节上不造成无谓的损失,供电企业要做好各方面的管理工作,特别是在防窃电的打击方面。根据众多窃电案例显示,窃电多从计量装置入手,因为计量箱内具隐蔽性,不易被发现。电能表计量电量是由电压、电流、功率因数三要素和时间的乘积决定,因此,改变三要素中的任何一个都可以使电能表慢转、停转、反转。
Energy, as a special merchandise, has features of production and consumption at the same time and invisibility. Power supply enterprises have to manage perfectly in order to avoid the loss of energy in its circulation, especially in preventing energy-pilfered. The cases of energy-pilfering showed that the action of energy- pilfering occurred starts from the measure devices due to uneasy finding in the box. The metering of energy is determined by multiplying voltage, current, power and time for watt- hour meters, thus changing one of the three factors can make watt - hour meters run slowly and reversely or even stop.
