Integrated multifunctional power distribution box

Abstract

This invention relates to the field of power distribution box technology, and discloses an integrated multifunctional power distribution box, including an upper box above ground and a lower box underground, with adjacent ends of the upper and lower boxes connected. The upper box has an electrical cavity for installing electrical components, which is sealed by a door during use. A transfer mechanism is included to handle different external and internal conditions of the power distribution box during use. By adding and setting a vacuum arc-extinguishing mechanism, when the power distribution box is used in a high-altitude environment, this mechanism not only improves the insulation performance of the electrical cavity through vacuum treatment, suppressing faults such as corona discharge and flashover that are prone to occur in high-altitude environments, and preventing arc generation in advance, but also quickly captures arc flash signals, pushes the arc away from the contacts and confines it to a designated area through magnetic field control, and achieves rapid arc extinguishing in conjunction with an arc-extinguishing grid.
