Description

Technical Field

[0001] This invention relates to the field of uninterrupted meter replacement technology, and in particular to an uninterrupted meter replacement device for end users in a park. Background Technology

[0002] The power supply business environment is an important indicator for power supply companies. Reducing power outage time for customers is a crucial part of improving the power supply business environment and also a significant factor affecting customer service satisfaction. Power outages in the marketing field are mainly caused by meter capacity expansion, metering device failure, meter repair, and batch meter replacement. All of these power outages revolve around metering devices. Therefore, how to reduce power outage time for customers in the marketing field and improve their sense of access to electricity has become an important issue.

[0003] For the upgrading and transformation of industrial parks, and the implementation of meter reading for end-user enterprises within the parks, power supply companies have found in their daily operation and maintenance management that most of the electricity users after meter reading was implemented are small and micro enterprises. The electricity consumption characteristics of these small and micro enterprises are large loads and rapid fluctuations. Power supply companies frequently receive requests from these customers to increase their electricity capacity. Currently, capacity increases and meter replacements are all done through power outages. Power outages of 2-5 hours cause inconvenience to customers' production. Therefore, the development of uninterrupted meter replacement devices for end-user enterprises in industrial parks has become an urgent issue that needs to be addressed.

[0004] Traditional uninterruptible meter replacement devices on the market have the following drawbacks: Traditional devices are generally used for residential meter replacements, such as the "contactless meter replacement handheld box." These devices primarily construct a power bypass at the meter box's inlet and outlet switches, capable of handling 12 amps of operating current. During meter replacement, residents no longer need to turn off high-power appliances, achieving "high load, truly seamless" operation. They can also monitor voltage, current, and contact temperature in real time, reflecting whether wiring is correct and the circuit is safe. Furthermore, they have built-in protection components that can replace air switches for short-circuit tripping, ensuring the safety of residents' electricity use during meter replacement. However, these devices cannot currently handle high-current loads, and they cannot continue to collect and measure customer electricity consumption during the replacement process, resulting in power loss for the power company during the replacement period. Summary of the Invention

[0005] The purpose of this invention is to propose an uninterrupted meter replacement device for end users in a park, which solves the technical problems of how to reduce energy loss and achieve high current flow during meter replacement.
