Abstract

The invention provides a mechanical-electrical integrated power distribution cabinet protective heat dissipation device, and belongs to the technical field of mechanical-electrical integration. The device comprises a protective box and a heat dissipation device. The heat dissipation device is symmetrically arranged in the left-and-right direction about the protective box. The heat dissipation device is connected to the inner wall of the protective box through upper and lower brackets. Multiple uniformly distributed heat dissipation holes are arranged on the side wall of the protective box corresponding to the heat dissipation device. The protective box is arranged outside the power distribution cabinet. When the protective box is impacted by a foreign object, the impact force first acts onthe first shock absorbing box and then is transmitted to the second connecting shaft and buffered by the second spring to eliminate the damage effect caused by the impact. Meanwhile, the damage effect caused by the side impact can be eliminated by the first spring so as to have the characteristics of good protective effect and high practicability; and when the protection box body is impacted by the foreign object, the impact force is transmitted to the second connecting shaft to be buffered by the second spring; air circulation is accelerated by the heat dissipation device and heat dissipation of the power distribution cabinet can be facilitated; and the heat dissipation holes are inclined downward from the inner wall of the protective box to the outside so as to effectively prevent dustfrom entering the power distribution cabinet.

Description

technical field [0001] The invention relates to an electromechanical integration device, in particular to a protective heat dissipation device for an electromechanical integration power distribution cabinet. Background technique [0002] Power distribution cabinets (boxes), as electromechanical integration equipment, power distribution cabinets (boxes), lighting distribution cabinets (boxes), and metering cabinets (boxes), are the final equipment of the power distribution system. The power distribution cabinet is a general term for the motor control center. The power distribution cabinet is used in the occasions where the load is relatively scattered and there are few circuits; the motor control center is used in the occasions where the load is concentrated and there are many circuits. They distribute the electric energy of a certain circuit of the upper-level power distribution equipment to the nearest load. This level of equipment shall provide protection, monitoring and...
