The lead seal of electric energy meter plays a vital role in the work of electric power measurement and management, which is mainly embodied in the following aspects:

Ensure the accuracy of measurement

As an instrument for measuring electric energy, the reading accuracy of electric energy meter is directly related to the fairness of electric power transaction and the economic interests of users. As a physical sealing means, lead seal can prevent non-professional people from unauthorized changes or adjustments to the meter, so as to ensure the accuracy of the meter. Once the watt-hour meter is sealed, except for the professional seal clamp mold, other personnel can not open at will, which provides a solid barrier for the accuracy of the meter measurement.

Second, to prevent electricity theft

Stealing Electricity is a great challenge in power management, which not only damages the economic interests of power enterprises, but also disturbs the normal order of power market. The use of electric energy meter seal can effectively prevent users or other illegal elements through changing the internal components of electric energy meter, tamper with wiring and other ways to steal electricity. The integrity and uniqueness of the lead seal make any illegal changes to the meter can be found and traced in time, so as to deter and prevent the theft of electricity.

III. Maintaining the order of the electricity market

Power Market is a complex and huge system, which needs to rely on various regulations and technical means to maintain its normal operation. As an important link in power metering management, the sealing of electric energy meter is of great significance for maintaining the order of power market. It ensures the transparency and fairness of electric power transaction, protects the legitimate rights and interests of electric power enterprises and users, and promotes the healthy development of electric power market.

Fourth, improve the efficiency of management

In power metering management, the use of lead seals can also significantly improve management efficiency. On the one hand, the integrity and uniqueness of lead seals make it easy for power companies to identify which meters have been illegally altered, thus quickly locating the problem and taking appropriate measures; on the other hand, through regular inspection and replacement of lead seals, power companies can find and solve the problems of energy meters in time to avoid metering errors and management loopholes caused by energy meter failure.

Promoting technological innovation

With the development of science and Technology and the development of power market, the lead sealing technology of electric energy meter is also being innovated and perfected. For example, the lead seals of modern electric energy meters are increasingly made of environmentally friendly materials such as plastics, which are convenient to use and reduce environmental pollution; Some advanced electric meter seals also built-in RFID chips and other intelligent components, which can achieve remote monitoring and data analysis of electric meter functions. These technical innovations not only improve the practicability and reliability of electric energy meter seal, but also bring more convenience and possibility for electric power metering management.

Detailed mechanism of action

Sealing process: the watt-hour meter will go through strict inspection and sealing before leaving the factory to ensure the accuracy of measurement. The power supply company will check the integrity of the lead seal when installing the power meter, and seal it again after the installation to ensure that it is not illegally altered.

Type and specification of lead seal: There are many kinds of specifications of lead seal for electric meter, such as square, circle, snap type, etc. . At the same time, the seal will be printed with a unique code segment to ensure its uniqueness.

Material and performance: the lead seal of modern electric meter is made of environment-friendly materials such as PC polycarbonate, which has high anti-radiation, acid and alkali resistance. These materials not only improve the durability of lead seals but also reduce environmental pollution.

Anti-counterfeiting and traceability: each meter sealed with a unique code number so that any illegal changes to the meter can be found and traced in time. Customers can also print their name LOGO and code on the seal to increase security.
