Product introduction:
Stealing electricity not only causes economic losses to the country and power supply enterprises, but also seriously damages the normal order of power supply and consumption, and even threatens the safe and stable operation of the power grid. The number of low-voltage power users is large and the distribution is wide, and the proportion of households stealing electricity is high, accounting for more than 98% of the total number of households stealing electricity. Therefore, the acts of stealing electricity must be severely cracked down. In view of this, our company has developed a low-voltage platform area on-site batch theft detection instrument, which is divided into hardware platform and software platform. The hardware platform can collect various data of smart electricity meters (hereinafter referred to as "electricity meters") in batches. The software platform can make comprehensive analysis of the collected data and identify the suspected customers of stealing electricity. This method can be used for real-time monitoring of hundreds of users in a certain area, and has the effect of fast, accurate and on-the-spot inspection. It is of great significance for low-voltage inspection of users' power consumption and improvement of economic benefits of power grid.
Product features:
1, mobile, flexible, support two modes of on-site detection and remote online monitoring;
2. Support synchronous operation of multiple diagnostic terminals in one platform area to improve collection rate and data timeliness;
3, support multiple platform area online monitoring, multi-thread data asynchronous transmission;
4. Support batch analysis of big data, accurately judge typical electric theft methods such as wrong wiring method, shunt method, undervoltage method and modification method in meter, generate abnormal analysis results of suspected electric theft, predict electric theft methods, estimate lost electric quantity, and summarize statistical statements of suspected electric theft;
5. Support continuous monitoring and tracking diagnosis of key suspected electric theft households, accumulate relevant electric theft information, obtain more and more evidence for electric theft, provide judgment basis and direction for on-site inspectors to obtain evidence for electric theft, and provide data support for the recovery of electric charges and fines;
6, support the meter reading scheme to customize the configuration of meter data items, such as: communication address, total active energy, three-phase voltage, three-phase current, zero current, loss of voltage, loss of current, open cover record and so on;
7, support suspected electricity theft and meter fault level four warning (red I yellow II blue III brown IV) function, and can automatically warn key suspected customers;
8. Support the independent operation of the diagnostic platform system, which does not conflict with the "use-acquisition" system and has no data association, ensuring the data security;
9. Comprehensive control of line loss in Internet of Things mode has been realized, which fundamentally changes working mode, improves working efficiency, reduces loss and increases efficiency.
