Description

Technical Field

[0001] The utility model relates to the technical field of distribution boxes, in particular to a high and low voltage distribution box. Background Art

[0002] As the name implies, high and low voltage distribution boxes are distribution equipment used for power distribution, control, metering and cable connection in power supply systems. Generally, power supply bureaus and substations use high voltage switch boxes, which are then stepped down by transformers and led out to low voltage distribution boxes on the low voltage side. The low voltage distribution cabinets are then used to distribute electricity to various distribution boards, control boxes, and switch boxes. The equipment inside is a distribution device that is assembled into one by some switches, circuit breakers, fuses, buttons, indicator lights, meters, wires and other protective devices to meet the design functional requirements.

[0003] After searching, a Chinese patent discloses a high and low voltage distribution box (authorization announcement number CN205595651U), which includes a box body, an operating chamber is provided at the front end of the box body, and the operating chamber is a square chamber. A card slot is provided on each side of the inner wall of the square chamber, and a slide slot is provided at the upper and lower ends of the inner wall of the square chamber. A box door is arranged on the front end face of the operating chamber, and the box door seals the entire operating chamber. A slider is installed in the slide slot, and the outer side surface of the slider is flush with the upper and lower end surfaces of the operating chamber. An axial hole is provided on the opposite surfaces of the two sliders, and a rotating shaft is provided at the upper and lower ends of the box door. The rotating shaft is arranged opposite to the axial hole on the slider, and the rotating shaft is arranged in the axial hole. The height of the box door is equal to the height of the operating chamber. Although the patented technology can be opened with a slight push when in use, the position of the two movable door panels relative to the box door can be adjusted to realize maintenance. When the temperature is high, the two movable door panels can also be slightly pushed open to leak a gap for heat dissipation; and the box door of the utility model can be moved left and right in the operating chamber, which is very flexible.

[0004] However, the above device still has some shortcomings in actual use. The most obvious one is that when it is necessary to repair the electronic components in the distribution box, it is necessary to rotate the box door. This setting will prevent the electronic components from being installed within the rotation radius of the box door, otherwise the electronic components will be scratched, and the electronic components will be far away from the operating cavity, requiring staff to lean in for maintenance, which makes it inconvenient for staff to inspect and maintain the electronic components in the distribution box. At the same time, when the temperature in the distribution box is too high, it is necessary to manually push the movable door panel to cool it down. In daily work, the staff cannot sense the temperature in the distribution box in time, and thus cannot dissipate the heat from the distribution box in time, and high temperature can easily damage the electronic components.
