Description

Technical Field

[0002] Electricity metering equipment is a measuring instrument that records the amount of electricity used by users. It is a basic tool for measuring electricity. The management of electricity metering equipment is the primary task of the power grid system to ensure the safe operation and accurate measurement of metering equipment. It is a key link in power marketing and an important means to prevent electricity theft. At present, electricity metering equipment still uses traditional lead seals as the first line of defense against electricity theft. However, traditional seals are simple and can only provide a simple protective function for electricity metering equipment on the surface. They are easy to imitate and open. It is difficult to distinguish the authenticity of simple lead seal codes, QR codes, bar codes, etc., and they can no longer meet the current needs of preventing electricity theft. Traditional lead seals have management loopholes such as multiple departments and multiple personnel, lack of digital information management methods, incomplete metering equipment ledgers, non-standard formats, and inadequate or untimely personnel inspections. In addition, manual inspection records are filled out with sloppy handwriting and difficult to save, and various statistical reports need to be manually entered after inspection, which increases repetitive work and is prone to errors, seriously affecting the operation of business census, inspection, metering equipment rotation and other work. At the same time, since construction personnel from external units have a large number of lead seals, there is a situation where new lead seals are installed after assisting in electricity theft, which brings great safety hazards to power metering equipment. Therefore, it is very necessary to provide an intelligent anti-theft lead seal for power metering equipment that can effectively protect power metering equipment, eliminate safety hazards of metering equipment, prevent the occurrence of electricity theft, and effectively improve the operation and maintenance management efficiency of metering equipment, and is easy to manage and reusable.
