Background

The rapid development of electric power construction is promoted by national economy development, and the perfection of the power utilization information acquisition system promotes the perfection of line loss refining management work. According to statistics, electricity stealing behaviors are the main reason of non-technical line loss, but electricity stealing phenomena can not be effectively restrained for a long time, and some illegal enterprises achieve the purpose of paying less electricity charges by means of counting less or even not counting electricity, so that a large amount of national electric energy loss and national property loss are caused. However, with the development of the technology, the electricity stealing means has the characteristics of concealment, diversification, rapidness and high technology, and especially in the situation that the special large users steal electricity, many users have concealed electricity stealing means and high technology content, and the conventional electricity inspection means is difficult to be effective. And the threat is brought to national property and national safety power utilization. In order to search for electricity stealing events of users, incoming line current of the users, current before an ammeter and current after the ammeter need to be collected and compared, but the existing electricity stealing prevention monitoring device generally adopts a box-type structure and is inconvenient to install.
