Description
Technical Field
[0001] This invention relates to the field of uninterrupted power meter replacement technology, and in particular to a portable uninterrupted power meter replacement device. 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] In implementing meter reading for end-user businesses in industrial parks, power supply companies have found in their daily operation and maintenance that most of the users are small and micro-sized enterprises (SMEs). These SMEs typically have high and rapidly fluctuating electricity loads, leading to frequent requests for capacity increases from them. Currently, capacity increases and meter replacements all involve power outages. These 2-5 hour outages cause significant inconvenience to customers' production. Therefore, the development of uninterrupted meter replacement devices for end-user businesses 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 in residential meter replacements, such as the "contactless meter replacement handheld box." These devices primarily construct a power bypass from the meter box's inlet and outlet switches, capable of handling 12 amps of operating current. During meter replacement, residents no longer need to shut down 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, leading to power loss for the power company. Generally, meter replacement requires a power outage for the customer, which severely impacts their normal production electricity needs. If the meter's inlet and outlet switches are directly short-circuited for replacement, while the customer's electricity supply is guaranteed, the electricity cannot be measured accurately and in a timely manner, resulting in power loss for the power company.
