Description

Technical Field

[0001] The utility model relates to the technical field of electric power equipment, and more specifically to a sealed explosion-proof distribution box for electric power engineering. Background Art

[0002] The distribution box is an electrical equipment with the characteristics of small size, easy installation, special technical performance, fixed position, unique configuration function, no site restrictions, universal application, stable and reliable operation, high space utilization, small footprint and environmental protection. It is the control center for commanding various components in the power supply line to reasonably distribute electric energy, the control link for reliably receiving upper power supply and correctly feeding load electric energy, and the key to obtaining user satisfaction with power supply quality.

[0003] At present, the small distribution boxes and power socket boxes used in building electrical appliances mainly include PXT(R), DCX(R), XXM(R) and other series, which are relatively good in structural shape, power supply continuity and anti-electric shock measures.

[0004] However, the panels of current sealed explosion-proof distribution boxes, such as the PXT(R) lighting explosion-proof distribution box, are mostly designed as concave-convex covers, with at least 100 fastening screws on the panel surface. Since there is no door on the panel, it is fixed by screws. Therefore, when repairing and replacing components such as circuit breakers or sockets, the panel must be disassembled, which is very inconvenient. Moreover, when the distribution box is embedded in the wall, it is often encountered that the distribution box panel and the wall surface cannot be matched due to the large error between the buried depth of the box body and the thickness of the wall paint. The operating handle of the distribution box with exposed switch handle is retracted into the panel and cannot be operated.

[0005] Therefore, how to provide a sealed explosion-proof distribution box for electric power engineering that can solve the above problems is an issue that technical personnel in this field urgently need to solve. Utility Model Content
