Description

Technical Field

[0001] The utility model relates to the technical field of power distribution cabinets, in particular to a direct current power distribution cabinet with an electric shock protection function. Background Art

[0002] DC distribution cabinets are divided into power distribution cabinets, lighting distribution cabinets, and metering cabinets. They are the final equipment of the power distribution system. Distribution cabinets are a general term for motor control centers. Distribution cabinets are used in places where the load is relatively dispersed and there are fewer circuits, while motor control centers are used in places where the load is concentrated and there are more circuits. They distribute the power of a circuit of the upper-level distribution equipment to the nearest load. This level of equipment should provide protection, monitoring, and control for the load.

[0003] For the sake of safety, the distribution cabinets used in the prior art are equipped with insulating rods inside for insulation protection. The cabinet itself does not carry current during normal use, but when damaged, it will release voltage to the outside. Or, after long-term use, the equipment and guides of the distribution cabinet will wear out. When the wires inside the distribution cabinet are damaged, leakage may occur in the cabinet, which is very dangerous and reduces the effect of the insulating rods. At this time, if pedestrians and maintenance workers touch the door of the distribution cabinet, there will be a great hidden danger, endangering personal safety. Utility Model Content
