Description

External protection device for power distribution cabinet

Technical Field

The utility model relates to an external protection device for a power distribution cabinet, belonging to the technical field of power distribution box equipment.

Background Art

The power distribution cabinet, also known as the distribution box, is centrally installed in the enterprise's substation to distribute electric energy to the lower-level power distribution equipment in different locations. It is a general term for the motor control center and is divided into power distribution cabinets, lighting distribution cabinets, and metering cabinets. It is the final equipment of the power distribution system. The power distribution cabinet is used in places where the load is relatively dispersed and there are fewer circuits. It distributes the electric energy of a circuit of the upper-level power distribution equipment to the nearest load and provides protection, monitoring and control for the load. Therefore, a complete set of switches, instruments and other equipment is centrally installed in the power distribution cabinet.

The patent document with application number CN202220086316.7 discloses an outdoor protective distribution cabinet with an anti-collision device on the outside, including a protective device, a first distribution cabinet shell, a supporting device, a second distribution cabinet shell and a connecting slot, wherein the first distribution cabinet shell and the second distribution cabinet shell are slidably connected at the center of the upper end surface of the supporting device, and the first distribution cabinet shell and the second distribution cabinet shell are slidably connected. The utility model provides a protective device, and the six groups of connecting springs and limit clamps inside the protective device can perform sufficient protective operations when the outside of the protective sleeve is impacted. At the same time, since the bottom of the protective sleeve is rotatably connected to the supporting device, the protective sleeve can remove the impact force by elastic rotation, and the connecting bottom plate can provide sufficient elastic twisting force for the unloading of the protective sleeve, thereby maximizing the protection performance of the distribution cabinet.

Although the above patent can remove the impact force through elastic rotation, greatly improving the protection performance of the distribution cabinet, the overall structure is relatively complex, the production is difficult, and the overall closed setting has poor heat dissipation and poses a safety hazard.

In summary, the existing technology obviously has inconveniences and defects in practical use, so it is necessary to improve it.
