Description

Technical Field

[0001] The utility model relates to the technical field of metering boxes, in particular to a low-voltage embedded metering box. Background Art

[0002] A meter box is a collection of metering instruments and auxiliary equipment necessary for measuring electrical energy, including energy meters, voltage and current transformers and their secondary circuits, energy metering panels, cabinets, and enclosures. Meter boxes can be mounted either suspended or floor-standing. To ensure installation quality, suspended boxes must be secured with built-in expansion bolts. The bolt sizes must meet safety and secure requirements and meet outdoor installation requirements. Its reliability not only impacts the safe, stable, and economical operation of smart grids, but also the reliability and safety of electricity use in every household. However, with the expansion of the Global Energy Internet, metering equipment is being installed in increasingly diverse locations, with increasingly complex geographical environments and increasingly diverse climates. In some regions, especially in harsh climates, metering equipment often malfunctions. Low-voltage meter boxes, as protective enclosures for smart energy meters, data collection terminals, disconnectors, and circuit breakers, are the first line of defense in ensuring fair, impartial, and accurate metering. Their quality and service life require stringent control to ensure truly safe and stable electricity use for users. Therefore, a new low-voltage embedded integrated meter box has been proposed.
