What are the defects of prepaid watt-hour meter? Seek an answer

The prepaid watt-hour meter is written by computer, which reduces human factors, and users can know their electricity consumption at any time, so that users can use electricity with confidence and understand electricity. Prepaid watt-hour meter can recover funds in time, plug loopholes, reduce the formation of enterprise arrears, put an end to electricity loss and reduce business risks.

The power consumption of prepaid watt-hour meter itself is below 0.8W, and the metering accuracy is above Grade 2. Even if the load is small, there will be counting pulses to measure. However, the power consumption of mechanical instruments is above 1.2W, and the measurement accuracy is poor. When the load is small, the instrument will not move. The line loss can be greatly reduced by using prepaid electric meters. For example, a village in Linzhang County installed 175 prepaid electricity meter. During the installation process, more than 30 backward meters such as DD28 10 were eliminated, and more than 30 meters were found to be inaccurate after inspection. Before installation, the low-voltage line loss of the village was 14%, and after installation, the line loss decreased to about 7%.

Shortcomings and deficiencies in the use of prepaid watt-hour meters. The software is not unified. At present, one electricity meter manufacturer has one charging system, which cannot be networked for unified management. If it is to be unified, it needs the cooperation of various manufacturers, but the cooperation of manufacturers is not realistic. Because the software is not uniform, each manufacturer has a set of electricity sales system. If the system is upgraded or fails, the maintenance and management of the system depends on the manufacturer, and the work of the power sector is very passive.

The function is defective, the user of single-row display watt-hour meter can't see the meter code, and the double-row display watt-hour meter may lose the counting pulse under heavy load, which leads to the inconsistency between the counter and the electronic display.

Because the purchase of watt-hour meters is a personal investment, the power sector has no financial subsidy, so it can only be purchased by watt-hour meter manufacturers in conjunction with the village Committee and sign a supply contract with the village.

Now, because the prepaid watt-hour meter is a set of systems in one factory and lacks unified management software, it is suggested that the competent department of electric power unify the software interface and norms for network management. Because the promotion of prepaid watt-hour meters is purchased by users, in order to strengthen the promotion, it is suggested that the competent department of electric power should give some subsidies in terms of funds. At the same time, we should strengthen the training management of prepaid watt-hour meters, formulate relevant policies and measures, increase inspection equipment and strengthen the verification of watt-hour meters.
