Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of low-voltage distribution equipment in electrical engineering, and in particular to a low-voltage distribution box. BACKGROUND

[0002] With the development of modern industry and construction, the demand for electricity is increasing, and safe and efficient power distribution has become the focus of attention. Although the traditional low-voltage distribution box meets the basic power distribution function, it is relatively backward in intelligent management, fault detection and elimination, and cannot adapt to the rapidly changing power environment and the demand for technological progress. In recent years, the construction of smart grid has promoted the upgrading of power distribution system, especially in improving energy efficiency, enhancing safety, and realizing remote monitoring, which has set higher standards.

[0003] The low-voltage distribution box commonly seen in the market is packaged with a metal shell, and various low-voltage circuit breakers, contactors, thermal relays and other elements are integrated inside to complete the functions of circuit connection, disconnection and overload protection. In order to deal with extreme situations such as short circuit, a fuse is usually provided as the last line of defense. However, these traditional designs have some limitations. First, most distribution boxes do not have self-diagnosis capabilities, making it difficult to quickly locate the problem when a fault occurs. Second, maintenance and repair are not convenient, especially in the case of dense wiring, it is extremely difficult to find line abnormalities. Finally, there is a lack of effective energy consumption monitoring mechanism, which is not conducive to fine management and energy saving.

[0004] The design of the existing low-voltage distribution box does not fully consider the future development trend, especially in terms of intelligence and networking, which is obviously lagging behind and cannot meet the higher requirements of modern buildings for power distribution facilities. In addition, the traditional products have a large volume and occupy more space, which does not conform to the current compact building design concept. Moreover, most products do not take adequate protective measures to resist the impact of external harsh conditions, such as moisture and high temperature, which easily damages them, reducing their service life and operational stability.
